Ingredients You’ll Need

The beauty of this Ground Beef and Potatoes Casserole is that every ingredient pulls its weight to build layers of flavor, texture, and color. This is straightforward comfort food, but a few simple tips will make your casserole shine.

Ground beef: Go for 80/20 beef for juicy, flavorful results without excess grease.
Onion: Diced small, onion adds subtle sweetness that balances the richness of the beef.
Garlic: Minced fresh garlic infuses every bite with savory depth—don’t skip it!
Salt: Essential for seasoning the beef and potatoes evenly.

How to Make Ground Beef and Potatoes Casserole

Step 1: Prep Your Oven and Dish

Start by preheating your oven to 375°F (190°C) so it’s perfectly hot when your casserole is ready to go in. Lightly grease a 9×13-inch baking dish with nonstick spray or a dab of butter. This small step ensures your casserole comes out without any sticky, cheesy mess left behind.

Step 2: Sauté the Onions and Garlic

In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté for 2–3 minutes until it softens and turns translucent—it should smell delicious already! Toss in the minced garlic and stir for another 30 seconds, just until fragrant but not browned.

Step 3: Brown the Beef

Add the ground beef directly into the skillet with the softened onions and garlic. Break the meat up with a spoon and cook until it’s deeply browned with crispy edges. Drain off any extra grease, then season the mixture generously with salt, pepper, paprika, and dried thyme for bold, balanced flavor in every forkful.

Step 4: Mix the Creamy Sauce

In a small bowl, whisk together the cream of mushroom soup, whole milk, and sour cream until you have a smooth, creamy sauce. This blend melts into the potatoes and beef as the casserole bakes, turning everything rich and luscious with minimal effort.

Step 5: Layer the Casserole

Now for the fun part! Spread half of the sliced potatoes in the bottom of your prepared baking dish, creating an even layer. Top with half the savory beef mixture, then sprinkle on 1/2 cup of cheddar cheese. Drizzle half of the soup mixture over the top. Repeat these layers once more using the remaining ingredients, and finish with all that glorious cheddar cheese.

Step 6: Bake and Finish

Cover your casserole tightly with aluminum foil and bake for 45 minutes. This allows everything to steam and meld together. After that, remove the foil and bake uncovered for another 15–20 minutes, until the potatoes are fork-tender and the cheese is bubbly and golden. Let your Ground Beef and Potatoes Casserole rest for at least 10 minutes to firm up—those cheesy, creamy layers are worth the wait! Just before serving, scatter chopped parsley across the top for a pop of color.

How to Serve Ground Beef and Potatoes Casserole

Garnishes

A simple garnish of chopped fresh parsley instantly brightens up the casserole and adds extra fresh flavor. If you’re feeling adventurous, try a dusting of smoked paprika or a few sliced scallions for color and zest. A handful of crispy fried onions are also delightful sprinkled on just before serving.

Side Dishes

This casserole is hearty on its own, but it truly shines alongside simple sides. Pair it with a crisp green salad or roasted vegetables to lighten up your plate. Warm dinner rolls or crusty bread are perfect for soaking up every last bit of that creamy sauce, and classic coleslaw brings a nice crunch that balances the richness.

Creative Ways to Present

If you’re hosting guests or looking to change things up, consider baking your Ground Beef and Potatoes Casserole in individual ramekins or small baking dishes for a personal touch. For a weeknight shortcut, scoop a portion over steamed green beans or serve atop a bed of wilted spinach for extra veggies and color.

Make Ahead and Storage

Storing Leftovers

Leftover Ground Beef and Potatoes Casserole tastes just as wonderful the next day. Simply let it cool, then cover the baking dish tightly or transfer to an airtight container. Store in the refrigerator for up to 4 days—just reheat and enjoy for an effortless meal.

Freezing

This casserole freezes beautifully. Let it cool completely, then wrap the dish in plastic wrap and foil (or slice into portions and use airtight containers). It will keep well in your freezer for up to 2 months. When you’re ready for a comforting dinner, thaw it overnight in the fridge.

Reheating

To reheat, cover the casserole with foil and warm in a 350°F (175°C) oven until heated through, about 20 to 30 minutes. Individual portions can also be microwaved in a pinch, just be sure to cover to retain moisture and heat in quick bursts to keep the cheese creamy.

FAQs

Can I substitute other types of potatoes?

Absolutely! Yukon Golds are an excellent swap for russets, and they don’t even need peeling. For an extra rustic touch and extra fiber, you can also use red potatoes, just be sure to slice them thin for best results.

What other cheeses work well in this casserole?

Feel free to try Monterey Jack, mozzarella, or a blend of cheeses for a gooier or slightly different flavor. Pepperjack can add a subtle kick if your family enjoys a bit of spice!

Can I add vegetables to the Ground Beef and Potatoes Casserole?

Yes! Stir in a handful of frozen peas or corn with the beef mixture, or layer in thin-sliced bell peppers or spinach for even more color and nutrition. This recipe is very flexible.

Is it possible to prepare the casserole ahead of time?

You sure can! Assemble the casserole and cover tightly. Chill in the fridge for up to 24 hours, then simply bake as directed when you’re ready—add a few extra minutes to the baking time if it’s cold from the fridge.

What’s the best way to make this casserole gluten-free?

To make your Ground Beef and Potatoes Casserole gluten-free, use a gluten-free cream of mushroom soup, or make your own béchamel sauce. Double-check your dried seasonings and cheeses to make sure there are no hidden sources of gluten.
