Why You’ll Love This Hearty Beef and Potato Casserole

This recipe is a classic for a reason. The combination of ground beef and potatoes creates a cozy, no-fuss dinner that even picky eaters go for. The casserole is easy to assemble, budget-friendly, and great for making ahead. Plus, it uses pantry staples, making it an ideal dish for busy nights.

The cheesy topping adds a comforting finish while the meat and potatoes underneath become tender and flavorful as they bake. You don’t need to be a pro in the kitchen to nail this one—it’s simple, reliable, and endlessly adaptable.

What Kind of Potatoes Work Best?

You want potatoes that hold their shape without getting too mushy. Yukon Gold or red potatoes are excellent choices here. They become tender while still keeping structure, so you get distinct layers instead of a mashed texture. Russet potatoes will work too but tend to soften more and may blend into the casserole more like a bake.

Ingredients for the Hearty Beef and Potato Casserole

The magic of this casserole lies in how these humble ingredients come together to create something greater than the sum of their parts. Nothing fancy here—just wholesome ingredients that build deep flavor with little effort.

Ground beef: Rich and hearty, this forms the base of the casserole and brings savory depth.
Potatoes: Sliced thin, they soak up the juices and soften beautifully during baking.
Onion: A sautéed onion adds a mellow sweetness and a savory foundation to the meat.
Garlic: Just a touch, minced finely, enhances the flavor without overpowering.
Cheddar cheese: Melted over the top, it adds that gooey, golden finish everyone craves.
Cream of mushroom soup: This brings creamy cohesion to the layers and helps keep everything moist.
Milk: Thins out the soup just enough for perfect spreading and baking.
Salt and pepper: Basic seasonings that help all the other flavors shine.

How To Make the Hearty Beef and Potato Casserole

Step 1: Prepare the Beef Mixture

In a large skillet over medium heat, cook the ground beef until no longer pink, breaking it up as it browns. Add the chopped onion and cook for another 3 to 4 minutes until the onion softens. Stir in the minced garlic, season with salt and pepper, and cook for another minute. Drain excess fat.

Step 2: Slice the Potatoes

Wash and peel your potatoes, then slice them into thin, even rounds. A mandoline helps, but a sharp knife will work just as well. Aim for slices about 1/8-inch thick so they cook evenly.

Step 3: Layer the Casserole

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Start by spreading half of the sliced potatoes in the bottom. Add half of the beef mixture on top. Repeat the layers once more with the remaining potatoes and beef.

Step 4: Mix the Sauce

In a small bowl, whisk together the cream of mushroom soup and milk until smooth. Pour this mixture evenly over the layered beef and potatoes.

Step 5: Bake and Add Cheese

Cover the casserole with foil and bake for 60 minutes. Then uncover, sprinkle shredded cheddar cheese on top, and return to the oven for 15 to 20 more minutes, or until the cheese is melted and bubbly.
