Ingredients You’ll Need for Instant Pot Mississippi Pot Roast

The beauty of Instant Pot Mississippi Pot Roast lies in its simplicity. With just a handful of ingredients, you can create a melt-in-your-mouth dish that’s full of flavor. Here’s a breakdown of what you’ll need to make this mouthwatering roast:

The Key Ingredients: Chuck Roast, Ranch, and Au Jus Mix

At the heart of this dish is the chuck roast, which is a cut of beef known for its tenderness and flavor when cooked slowly. The marbling in chuck roast breaks down during cooking, ensuring that the meat is juicy and fork-tender. You can also use other cuts of beef like brisket or round roast, but the chuck roast is generally considered the best choice for Mississippi Pot Roast.

Next, we have the ranch dressing mix. This seasoning mix adds a creamy, herby flavor that pairs perfectly with the beef, giving the roast a deliciously tangy kick. If you prefer to avoid store-bought packets, you can make your own homemade ranch seasoning using ingredients like dried dill, garlic powder, onion powder, and parsley.

The au jus gravy mix is another essential ingredient that contributes depth to the flavor profile of the dish. This savory packet seasoning adds a rich, beefy taste to the pot roast, creating a comforting gravy-like sauce that coats the meat. The combination of ranch seasoning and au jus gravy mix is what gives the Mississippi Pot Roast its signature flavor.

Pepperoncini Peppers: The Secret to Flavor

One of the key distinguishing features of Mississippi Pot Roast is the inclusion of pepperoncini peppers. These mild, tangy peppers add just the right amount of heat and acidity to balance the richness of the roast and the seasoning mix. The juice from the pepperoncini also infuses the meat with additional flavor, ensuring that every bite is bursting with zesty goodness.

The pepperoncini peppers provide a gentle, tangy kick without overwhelming the dish, making them perfect for those who like a little spice but not too much heat. If you prefer more spice, you can add extra pepperoncini or even swap in banana peppers for a different flavor.

Optional Additions: Beef Broth and Seasonings

While the Instant Pot will do most of the work, some optional ingredients can enhance the flavor and texture of your Mississippi Pot Roast. Beef broth can be added to the pot for extra moisture and a more robust flavor. If you want your roast to be extra juicy, consider adding a cup of beef broth. If you don’t have broth on hand, water can work as a substitute.

For those who like to adjust the seasoning to their tastes, you can also add freshly ground black pepper and salt to enhance the flavor further. If you enjoy extra garlic flavor, a sprinkle of garlic powder or some minced garlic can add depth.

Some variations of Mississippi Pot Roast also include onion powder, parsley, or dried thyme for additional flavor complexity. These ingredients are entirely optional, but they can make your roast even more flavorful if you’re looking to customize the dish.

Choosing the Right Cut of Beef for Pot Roast

While the chuck roast is the most recommended cut, choosing the right beef cut for your roast can make a big difference in tenderness and taste. Chuck roast is perfect for braising and pressure cooking, as it breaks down beautifully in the Instant Pot and becomes incredibly tender. If you prefer leaner cuts, you might opt for round roast, but be mindful that it may not be as tender without extended cooking time.

Whichever cut you choose, look for well-marbled beef to ensure the roast stays juicy throughout the cooking process. The fat will melt during cooking, infusing the meat with flavor and helping to create a moist, melt-in-your-mouth texture.

By focusing on these core ingredients—chuck roast, ranch seasoning, au jus gravy mix, and pepperoncini peppers—Instant Pot Mississippi Pot Roast comes together with ease. The optional additions allow you to customize the dish to your preferences, while the key ingredients work in harmony to create a flavorful, tender roast that everyone will enjoy. With just a few simple ingredients, you’ll have a comforting, crowd-pleasing meal ready in no time.

Making the best Instant Pot Mississippi Pot Roast is simpler than you might think, thanks to the magic of the Instant Pot. This section will walk you through each step to ensure that your roast turns out perfectly tender, flavorful, and full of mouthwatering goodness. Let’s break it down:

1. Preparing and Searing the Chuck Roast

The first step in making a perfect Mississippi Pot Roast is to prepare the chuck roast. Start by trimming off any excess fat from the roast, but leave a little fat on to ensure the roast stays moist during the cooking process. While this step is optional, it’s worth noting that searing the roast before pressure cooking can significantly enhance the flavor by creating a rich, caramelized crust on the outside.

To sear the roast, set your Instant Pot to the “Sauté” function and add a tablespoon of olive oil. Once the oil is hot, place the roast in the pot and sear it on all sides for about 3-4 minutes each, until it has a golden-brown crust. Searing not only helps lock in the juices but also adds depth to the flavor of your roast. Once seared, remove the roast from the Instant Pot and set it aside.

2. Adding the Seasonings and Ingredients

With the roast seared and set aside, it’s time to prepare the Instant Pot to cook the roast. Start by adding the ranch dressing mix and au jus gravy mix directly into the Instant Pot. You’ll also want to add a few of the pepperoncini peppers, along with some of their juice, to give the dish that signature tangy, zesty flavor.

To intensify the flavor, pour in about 1 cup of beef broth (or water if you prefer) into the pot, ensuring that it covers the bottom. This will help prevent the roast from burning and create a flavorful cooking liquid that transforms into a rich gravy. If you like a stronger pepper flavor, feel free to add more pepperoncini peppers at this stage.

3. Setting the Instant Pot for Perfect Results

Now that all your ingredients are in place, return the seared chuck roast to the Instant Pot, nestling it into the liquid and seasoning mixture. For even cooking, ensure the roast is mostly submerged in the flavorful broth.

Secure the lid on the Instant Pot and make sure the valve is set to “Sealing”. Set the Instant Pot to “Pressure Cook” (or “Manual”) on high for 60-75 minutes depending on the size of your roast. For a 3-4 lb roast, 60 minutes should be sufficient. If you’re cooking a larger roast, you may need to adjust the time by 10-15 minutes.

Once the cooking time is complete, let the Instant Pot naturally release pressure for about 10 minutes before switching the valve to “Venting” to release the remaining pressure. This step ensures that your roast stays tender and juicy.

4. Tips for Achieving the Perfect Tenderness

After the pressure has fully released, carefully remove the roast from the Instant Pot and transfer it to a cutting board. The meat should be so tender that it falls apart easily with a fork. If you want to shred the roast for sandwiches or serving over mashed potatoes, use two forks to pull the beef apart into bite-sized pieces. You can also serve the roast in larger chunks, depending on your preference.

At this point, you can also use the remaining cooking liquid in the Instant Pot to create a rich, flavorful gravy. Simply select the “Sauté” function again and let the sauce simmer for a few minutes until it thickens to your desired consistency. If you want a thicker gravy, you can whisk in a little cornstarch or flour slurry to achieve the perfect texture.

Tips for Success:

  • Do not skip the searing step if you can help it. It adds so much flavor to the roast that it’s worth the extra time.
  • Customize the pepper heat by adding more or fewer pepperoncini peppers based on your spice tolerance.
  • If you prefer a saucy roast, you can always add more beef broth or water during the cooking process.
  • Double the recipe if you’re cooking for a larger crowd—just ensure the roast fits comfortably in your Instant Pot.

By following these steps, you’ll have a tender, flavorful Mississippi Pot Roast that’s ready to impress everyone at your table. The Instant Pot makes it easy to achieve perfect results every time, and the added benefit of minimal hands-on time means you can relax while the pressure cooker works its magic. Enjoy the savory goodness and make this your go-to recipe for busy weeknights or weekend feasts!

How to Serve Your Mississippi Pot Roast

Once your Instant Pot Mississippi Pot Roast is perfectly cooked, it’s time to serve it up! This flavorful roast is incredibly versatile and can be paired with a variety of sides, transforming it into a hearty meal that everyone will enjoy. Here are some delicious and creative ways to serve your Mississippi Pot Roast:

1. Over Mashed Potatoes or Rice: The Classic Choice

One of the most popular ways to serve Mississippi Pot Roast is over a bed of creamy mashed potatoes or fluffy rice. The rich, savory gravy from the roast complements the soft texture of mashed potatoes, creating a comforting and satisfying meal. The potatoes absorb the flavors of the roast and gravy, making each bite even more indulgent.

  • Mashed Potatoes: For the ultimate creamy experience, make mashed potatoes with butter, cream, and a touch of garlic. The smooth texture will soak up the savory sauce, and the richness pairs perfectly with the tangy kick of the pepperoncini peppers.
  • Rice: For a lighter option, serve your Mississippi Pot Roast over white or brown rice. The rice will absorb the flavorful juices, offering a deliciously simple base for the roast. If you want to make it extra special, try serving it over seasoned rice, like garlic rice or rice pilaf, to complement the roast’s bold flavors.

2. Serve It on Sandwich Buns for a Hearty Meal

Mississippi Pot Roast is also fantastic as a roast beef sandwich. After shredding the roast, pile it high on a soft sandwich bun, and spoon some of the flavorful gravy over the top. This makes for a perfect, handheld meal, and it’s an easy way to serve the roast for lunch or a casual dinner.

  • Add Cheese: Top your sandwich with a slice of provolone or mozzarella for a melty, gooey addition that elevates the flavor profile.
  • Pickles or Jalapeños: For a zesty twist, consider adding a few extra pickled pepperoncini or jalapeños to the sandwich for more tang and heat. You can also add some creamy coleslaw or a handful of crispy lettuce for crunch.

3. Pairing with Vegetables for a Complete Meal

Mississippi Pot Roast is already packed with flavor, but pairing it with a side of vegetables makes for a balanced and complete meal. The roast’s richness is offset by the freshness and lightness of vegetables, making each bite more exciting. Here are some great options to pair with your roast:

  • Roasted Vegetables: Roasted carrots, potatoes, and parsnips are a great complement to the pot roast. The caramelization from roasting enhances the natural sweetness of the vegetables, providing a perfect contrast to the savory beef. You can even toss the vegetables in some of the cooking juices for extra flavor.
  • Green Beans: Lightly sautéed or steamed green beans are another excellent option. Their fresh, crisp texture provides a delightful contrast to the tender roast. You can also try sautéing green beans with garlic and olive oil to add more flavor.
  • Brussels Sprouts: Roasted or sautéed Brussels sprouts with a touch of balsamic vinegar pair beautifully with the richness of the Mississippi Pot Roast. The slightly bitter flavor of Brussels sprouts complements the sweetness and tang of the roast’s gravy.

4. Leftover Ideas: Make It Into a Soup or Stew

Mississippi Pot Roast is perfect for leftovers and can be transformed into a delicious new meal the next day. After enjoying the roast, use the remaining meat and gravy to create a flavorful beef stew or soup.

  • Beef Stew: Shred the leftover roast and simmer it with diced vegetables like carrots, celery, and potatoes in the leftover gravy. Add a bit more broth to create a rich, hearty stew. Season with additional herbs or spices to taste.
  • Soup: For a lighter version, add the leftover beef and gravy to a pot with some beef broth and diced vegetables, like onions, carrots, and tomatoes, for a comforting soup. You can also throw in some noodles or rice for a complete meal.

5. Serving with a Side Salad for Balance

If you’re looking for a lighter side dish to balance the richness of the Mississippi Pot Roast, a fresh side salad is a great choice. A crisp, vibrant salad helps cut through the fattiness of the roast and adds a refreshing contrast.

  • Mixed Greens: A simple salad with mixed greens, cherry tomatoes, cucumbers, and a tangy vinaigrette works wonderfully. The acidity from the dressing will provide a nice contrast to the savory, tangy flavors of the roast.
  • Coleslaw: If you’re serving the roast on sandwiches, a side of creamy coleslaw is a fantastic option. The crunchiness of the slaw complements the tender roast, and the tanginess of the dressing pairs well with the roast’s bold flavors.

Additional Serving Tips:

  • Garnish: For added flair, garnish your dish with freshly chopped parsley or green onions. This adds a pop of color and freshness to the plate.
  • Gravy: Don’t forget to serve the extra gravy from the Instant Pot alongside your roast. You can drizzle it over your mashed potatoes, rice, or even the sandwich for an added boost of flavor.
  • Side Dips: If you’re serving the roast on sandwiches, consider offering dipping sauces on the side—something like horseradish sauce or a creamy ranch dip to complement the flavor.

Serving your Instant Pot Mississippi Pot Roast is all about balance and creativity. Whether you keep it traditional with mashed potatoes, try it as a sandwich, or pair it with fresh veggies, this roast will always be a crowd-pleaser. And with leftovers, the possibilities for transforming the dish into something new and equally delicious are endless. Enjoy the versatility of this recipe, and have fun experimenting with your favorite sides!

FAQs about Instant Pot Mississippi Pot Roast

Instant Pot Mississippi Pot Roast is a simple, flavorful dish, but you may have some questions about how to make it or adjust it to suit your preferences. Here are some frequently asked questions (FAQs) to help guide you as you cook this delicious roast.

1. Can I Use a Slow Cooker Instead of an Instant Pot?

Yes, you can absolutely make Mississippi Pot Roast in a slow cooker instead of an Instant Pot. While the Instant Pot uses pressure cooking to significantly reduce cooking time, the slow cooker offers a more hands-off, slow-cooked approach that results in tender, fall-apart meat.

  • Slow Cooker Method: To adapt the recipe, simply sear the roast in a skillet before adding it to your slow cooker (this step is optional but recommended for extra flavor). Add all the ingredients as you would for the Instant Pot, then cook on low for 7-8 hours or high for 4-5 hours, depending on the size of the roast. The result will be a wonderfully tender roast with the same rich, savory flavors.

2. How Can I Make This Recipe Spicier?

If you enjoy a little more heat in your Mississippi Pot Roast, there are several ways to increase the spiciness:

  • Extra Pepperoncini: Add more pepperoncini peppers to the roast. The pepperoncini peppers are mild but provide a tangy kick, and extra peppers will enhance that flavor without being overwhelmingly spicy.
  • Add Hot Peppers: For a more noticeable spice, you can include jalapeños or banana peppers. Slice them and add them to the pot for an extra layer of heat. You can also add a pinch of cayenne pepper or crushed red pepper flakes to kick up the spice level.
  • Hot Sauce: If you like a vinegary heat, consider adding a few dashes of your favorite hot sauce. This can complement the tanginess of the pepperoncini and add a deeper, spicier profile.

3. Can I Freeze Leftovers?

Yes, Mississippi Pot Roast makes fantastic leftovers, and you can easily freeze it for later use. Here’s how to store it:

  • Freezing the Roast: Allow the cooked roast to cool completely before transferring it into an airtight container or heavy-duty freezer bag. Be sure to include some of the gravy as well, as it helps keep the meat moist when reheated. Label the container with the date so you can keep track of its freshness.
  • Reheating: When ready to eat, you can reheat the roast in the Instant Pot, a slow cooker, or even on the stove. If reheating in the Instant Pot, use the “Sauté” function and stir occasionally until heated through. If using a slow cooker, set it on low for 2-3 hours until the roast is hot and tender again.

Frozen leftovers can last up to 3 months, but for the best flavor and texture, try to consume them within 1-2 months.

4. How Long Should I Cook the Roast for Best Results?

The cooking time for Instant Pot Mississippi Pot Roast can vary depending on the size of your roast, but generally, you’ll want to cook it for 60-75 minutes at high pressure.

  • 3-4 lb Roast: For a roast that’s around 3-4 pounds, set your Instant Pot to 60 minutes. This should be enough to break down the tough fibers and create a tender, juicy roast.
  • 5 lb Roast or Larger: If your roast is on the larger side (5 lbs or more), consider increasing the cooking time to about 75 minutes. For a roast that is particularly thick or tough, you may need to cook it for up to 90 minutes to ensure it reaches the desired tenderness.

After the cooking time is complete, let the Instant Pot naturally release pressure for at least 10 minutes to prevent the roast from drying out.

5. Can I Use Other Cuts of Beef for This Recipe?

While chuck roast is the traditional cut for Mississippi Pot Roast due to its tenderness and marbling, you can substitute it with other cuts of beef, although the results may vary slightly:

  • Brisket: This cut works well, especially if you enjoy a beefier flavor. You may need to cook it a little longer since brisket is often tougher than chuck roast, but it will still turn out tender and flavorful.
  • Round Roast: A round roast is leaner than chuck roast, so while it will cook up nicely, it may not be as tender and juicy without a longer cooking time. If using round roast, try adding a little extra broth or seasoning to help keep it moist.
  • Rump Roast: Another good substitute, though it can be a bit leaner than chuck roast. It can still become tender with the right cooking time, but be mindful of the cooking time to avoid drying it out.

While these cuts can be used, chuck roast remains the top choice for its balance of tenderness and flavor.

6. Can I Make This Recipe Without Ranch Dressing Mix?

Yes, you can make Mississippi Pot Roast without the ranch dressing mix if you prefer a homemade version or if you’re avoiding packaged ingredients.

  • Homemade Ranch Seasoning: Create your own ranch seasoning by combining dried dill, onion powder, garlic powder, dried parsley, salt, and black pepper. A general ratio is 1 tablespoon each of dill, onion powder, and garlic powder, and 1 teaspoon of salt and pepper. This homemade version will provide the same creamy, herby flavor without the need for a pre-made mix.
  • Alternative Seasonings: If you don’t want to make ranch seasoning, you can substitute with other seasonings like Italian seasoning, onion soup mix, or beef bouillon granules for a different flavor profile.

7. Can I Make This Recipe Gluten-Free?

Yes, Instant Pot Mississippi Pot Roast can easily be made gluten-free with a few simple swaps:

  • Ranch Dressing: Check the ingredients of your ranch dressing mix to ensure it doesn’t contain any gluten. There are many gluten-free ranch seasoning options available, or you can make your own homemade ranch seasoning as described above.
  • Au Jus Gravy Mix: Traditional au jus gravy mixes often contain gluten, so look for a gluten-free au jus mix at the store or make your own from scratch using beef broth and seasonings.

With these swaps, you can enjoy a delicious gluten-free version of this recipe without sacrificing any flavor.
