Ingredients
Here’s everything you’ll need:
-
6 medium russet potatoes, peeled and thinly sliced
-
2 cups shredded cheddar cheese
-
1 cup heavy cream
-
1 cup milk
-
2 tablespoons unsalted butter
-
1 teaspoon garlic powder
-
1 teaspoon onion powder
-
Salt and black pepper, to taste
-
1 cup breadcrumbs
-
1/4 cup grated Parmesan cheese
Step-by-Step Instructions
Follow these easy steps for a deliciously creamy and cheesy potato casserole:
Step 1 – Preheat and Prep
Preheat your oven to 375°F (190°C).
Grease a disposable aluminum tray or 9×13-inch baking dish with butter to prevent sticking.
Step 2 – Layer the Potatoes
Arrange half of the thinly sliced potatoes in the bottom of the dish, overlapping the slices slightly like shingles for even cooking.
Step 3 – Make the Cream Sauce
In a small saucepan over medium-low heat:
-
Combine 1 cup heavy cream, 1 cup milk, 1 teaspoon garlic powder, 1 teaspoon onion powder, salt, and pepper.
-
Stir gently and warm until heated through, but do not let it boil.
Tip: Warming the cream mixture helps it soak into the potatoes evenly.
Step 4 – Build Layers
Pour half of the warm cream mixture evenly over the potato layer.
Sprinkle 1 cup of shredded cheddar cheese over the top.
Add the remaining potato slices in a second layer.
Top with the rest of the cream mixture and remaining 1 cup of cheddar cheese.
Step 5 – Add the Topping
In a small bowl, mix:
-
1 cup breadcrumbs
-
1/4 cup grated Parmesan cheese
Sprinkle this mixture evenly over the top layer of cheese.
Dot with small pieces of the 2 tablespoons butter for extra richness.
Step 6 – Bake Covered
Cover the dish tightly with aluminum foil.
Bake in the preheated oven for 45 minutes to allow the potatoes to soften.
Step 7 – Bake Uncovered
Remove the foil.
Bake for another 15–20 minutes, or until:
-
The topping is golden brown
-
The potatoes are fork-tender
-
The casserole is bubbling at the edges
Step 8 – Rest and Serve
Allow the casserole to cool for 5–10 minutes so it sets slightly and is easier to serve.
Scoop onto plates and enjoy warm!
Variations & Tips

Substitute sweet potatoes for a naturally sweeter, nutrient-packed casserole.
Gluten-Free:
Use gluten-free breadcrumbs or skip the breadcrumb topping altogether.
Make Ahead:
Assemble the casserole a day ahead, cover, and refrigerate. Bake just before serving, adding 5–10 minutes to the baking time if chilled.

Frequently Asked Questions
Can I freeze this potato casserole?

How do I reheat leftovers?
Cover the casserole with foil and reheat in a 350°F (175°C) oven for 15–20 minutes, or until warmed through.
