Ingredients You’ll Need

• 3 lbs russet potatoes, peeled and thinly sliced
• 2 cups heavy cream
• 1 cup whole milk
• 2 cups shredded cheddar cheese
• 1 cup shredded Monterey Jack cheese
• 1/2 cup grated Parmesan
• 3 tbsp butter
• 3 cloves garlic, minced
• 1 tsp salt
• 1/2 tsp black pepper
• 1/4 tsp nutmeg (optional)
• Fresh parsley for garnish

Chef notes:

• Fresh garlic = bigger flavor.
• Thin slices cook evenly.
• Use unsalted butter to control salt.
• Grate cheese fresh if possible.
• Nutmeg is subtle; try a pinch first.
  Also, this gratin pairs nicely with seafood, like Ruth’s Chris crab cakes, if you want to dress up the meal.

How to Make It

1. First, preheat the oven to 350°F (175°C). Get your baking dish ready and butter the bottom so potatoes don’t stick.
2. Then, layer the thinly sliced potatoes in a large baking dish, overlapping slightly; they should look like fish scales.
3. Meanwhile, whisk heavy cream, whole milk, minced garlic, salt, pepper, and nutmeg in a bowl until smooth and fragrant.
4. Next, pour the cream mixture evenly over the potatoes so the layers soak through; press down gently to settle them.
5. After that, sprinkle the cheddar, Monterey Jack, and Parmesan across the top and dot with butter; the cheese will melt into a lovely crust.
6. Cover the dish with foil and bake for 40 minutes; steam will help the potatoes cook through.
7. Then remove the foil and bake another 10–15 minutes until the top is golden, bubbly, and edges show a little brown. You’ll smell an inviting toasty note.
8. Finally, let the gratin rest for a few minutes so it sets; run a knife around the edge, slice, and garnish with fresh parsley before serving.

Done looks like a bubbling, golden surface with tender slices that hold shape when lifted.

Kitchen Tips (From My Kitchen)

1. Time-saver: Slice potatoes on a mandoline for uniform pieces and quicker assembly.
2. Common mistake + fix: If the top browns too fast, tent foil loosely and continue baking so the center finishes without burning.
3. Simple variation: Stir in a teaspoon of Dijon mustard or sprinkle thyme for a bright lift.

Serving Ideas

• Holiday side: Serve with roasted beef and green beans for an elegant plate.
• Weeknight comfort: Pair with a simple green salad and roasted chicken.
• Brunch idea: Cut squares and serve alongside eggs and smoked salmon.
• For a casual dinner, add crusty bread and a lemony slaw. Also try pairing with sausage with potatoes and green beans for a hearty spread.

Optional garnish: chopped parsley or chives, and an extra sprinkle of Parmesan.

Storing & Leftovers

• Fridge: Store in an airtight container up to 3–4 days.
• Freezer: Freeze portions in a sealed container for up to 2 months; thaw overnight before reheating.
• Reheat: Warm in a 350°F oven covered for 15–20 minutes to protect texture and crisp the top briefly.

Leftover idea: Turn slices into a breakfast bowl with a fried egg and hot sauce.

FAQs

Q: Can I make this ahead?
A: Yes. Assemble, cover, and refrigerate up to 24 hours; bake as directed, adding a few extra minutes if cold.

Q: What can I substitute for heavy cream?
A: You can use half-and-half mixed with a little butter, but expect a slightly lighter finish.

Q: How do I know it’s done?
A: The potatoes should be tender when pierced with a knife, and the top will be golden and bubbling. Expect a set center that holds when sliced.

Q: Can I freeze Ruth’s Chris Gratin Potatoes?
A: You can freeze baked portions, though texture is best when reheated gently; freeze only if needed.
