What Kind of Potatoes Work Best for This Casserole?

Russet potatoes are your best bet here. Their starchiness allows them to soften beautifully without turning mushy, and they absorb the creamy sauce perfectly. If you prefer a waxier texture, Yukon Gold potatoes are another great option, offering a buttery flavor and rich texture.

How To Make the Hearty Beef and Potato Casserole

Step 1: Cook the Beef Mixture

In a large skillet over medium heat, cook 1 lb of ground beef with 1 diced yellow onion until the beef is browned and the onion is soft, about 6–7 minutes. Add 2 cloves minced garlic, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and 1/2 teaspoon paprika. Cook for another minute, then remove from heat.

Step 2: Prepare the Cream Sauce

In a saucepan, melt 3 tablespoons butter over medium heat. Whisk in 3 tablespoons all-purpose flour and cook for 1 minute to form a roux. Slowly add 2 cups of whole milk, whisking constantly to avoid lumps. Simmer until thickened, then stir in 1 1/2 cups shredded cheddar cheese until melted and smooth.

Step 3: Layer the Casserole

Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. Spread a thin layer of sauce on the bottom. Layer half the thinly sliced russet potatoes (about 3 medium potatoes), followed by half the beef mixture and more sauce. Repeat the layers and finish with remaining sauce and a sprinkle of cheese on top.

Step 4: Bake Until Golden and Tender

Cover with foil and bake for 45 minutes. Uncover and bake an additional 20 minutes until the top is golden and bubbling. Let it sit for 10 minutes before serving. Garnish with chopped fresh parsley if desired.

Frequently Asked Questions

Can I add vegetables to the layers?
Absolutely. Sautéed mushrooms, spinach, or steamed green beans make great additions.

How do I slice the potatoes evenly?
Use a mandoline slicer for uniform thin slices. Aim for 1/8 inch thickness so they cook evenly.

Can I make this casserole ahead of time?
Yes, assemble it up to a day in advance, cover tightly, and refrigerate. Bake when ready.

What cheeses work besides cheddar?
Mozzarella adds gooeyness, Gruyère adds nuttiness, and Monterey Jack offers a mild melt.
