Chicken and Broccoli Casserole Recipe – Cozy, Cheesy, and Simple

Ingredients You’ll Need

• 2 cups cooked chicken, shredded or diced
• 2 cups cooked rice
• 2 cups broccoli florets (fresh or frozen)
• 1 can (10.5 oz) cream of chicken soup
• 1 cup sour cream
• 1½ cups shredded cheddar cheese, divided
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• Salt and pepper to taste

Chef notes:

• Use rotisserie chicken for speed.
• Fresh garlic = bigger flavor (optional).
• Frozen broccoli thaws quickly under hot water.
• Choose sharp cheddar for more bite.

How to Make It

1. First, preheat the oven to 350°F (175°C). Grease a medium casserole dish.
2. Next, toss the cooked chicken and cooked rice into a large bowl. Add broccoli florets.
3. Then stir in the cream of chicken soup and sour cream until the mixture looks creamy and even.
4. Meanwhile, fold in 1 cup of the shredded cheddar, garlic powder, onion powder, salt, and pepper. Mix until everything is coated.
5. Now transfer the mixture to your greased casserole dish and smooth the top with a spoon. Sprinkle the remaining ½ cup of cheddar evenly over the top.
6. Bake for 30 minutes, until cheese bubbles and edges turn golden. You’ll smell the cheese and see small browned spots.
7. Finally, let it cool for 5 minutes so the casserole firms up. Serve warm and enjoy the melty texture.

For a helpful riff on rice ratios, I sometimes glance at a chicken broccoli rice casserole when I want more or less rice.

Kitchen Tips (From My Kitchen)

1. Time-saver: Use rotisserie chicken and frozen broccoli to cut prep to 10 minutes.
2. Common mistake + fix: If the casserole turns watery, bake uncovered longer to evaporate extra liquid.
3. Simple variation: Stir in 1 teaspoon Dijon mustard or a pinch of smoked paprika for depth.

Serving Ideas

• Weeknight dinner: Pair with a simple green salad and crusty bread.
• Brunch: Serve alongside roasted tomatoes and a poached egg.
• Holiday side: Make in a smaller dish as a warm buffet option.
  Garnish with chopped parsley or extra cracked pepper for a bright finish. Also, try a squeeze of lemon if broccoli tastes dull.

Include a taste-boosting nod to comfort by serving with my take on a ranch chicken and rice casserole as a companion dish for bigger crowds.

Storing & Leftovers

• Fridge: Store covered up to 3–4 days.
• Freezer: Freeze in portions up to 3 months; thaw overnight in fridge.
• Reheat: Warm in the oven at 325°F for 15–20 minutes to keep texture firm.

Leftover idea: Turn slices into a hearty sandwich with extra cheddar and a smear of mustard.

FAQs

Q: Can I make this ahead?
A: Yes. Assemble it, cover, and refrigerate overnight. Then bake as directed; add 5–10 minutes if cold.

Q: What can I swap for rice?
A: Try quinoa or small pasta like orzo. For a lower-carb option, use cauliflower rice. This keeps the idea of Chicken and Broccoli Casserole but shifts the base.

Q: How do I know it’s done?
A: The cheese should bubble and brown slightly. The center should feel set when you nudge the dish.

Q: Can I freeze it?
A: Yes. Freeze before baking in a foil dish, then bake from frozen but add 10–20 minutes to the time.

Final Thoughts

This Chicken and Broccoli Casserole is the kind of meal I turn to when I want simple comfort that still impresses. It’s forgiving, quick, and packed with familiar flavors, so tweak it and make it yours. I hope you enjoy it as much as my family does—especially on slow, cozy evenings when you need a warm, filling dish like Chicken and Broccoli Casserole.
