This easy beef and potato casserole is the kind of dinner that saves a hectic weeknight. It’s hearty, cheesy, and comes together fast.

Last Tuesday, my kid actually asked for seconds — that rarely happens. Here’s why this recipe works: it uses simple pantry ingredients, layers them in one dish, and bakes up golden and bubbly in under an hour.

Why You’ll Love This Easy Beef and Potato Casserole

• No pre-cooking the potatoes — just slice them thin and they cook right in the oven. So easy.
• The ground beef gets seasoned with garlic, onion, and paprika, so every bite is savory and warm.
• You can swap in whatever cheese you have on hand — cheddar, mozzarella, or a mix.
• It’s forgiving: if you’re short on time, use frozen hash browns instead of fresh potatoes.

Ingredients for This Easy Beef and Potato Casserole

• 1 lb (450g) ground beef
• 1 medium onion, diced
• 2 cloves garlic, minced
• 1 tsp paprika
• 1/2 tsp salt
• 1/4 tsp black pepper
• 3 medium Yukon Gold or Russet potatoes, thinly sliced (about 1/8-inch thick)
• 1 can (10.5 oz) cream of mushroom soup
• 1/2 cup milk
• 1 cup shredded cheddar cheese
• 1/4 cup chopped fresh parsley (optional, for garnish)

Note: For an even quicker easy beef and potato casserole, use frozen hash browns — no slicing needed. Just thaw and pat dry first.

How to Make This Easy Beef and Potato Casserole

1. Preheat oven to 375°F. In a large skillet, cook the ground beef over medium-high heat until browned, breaking it up with a spoon — about 5 minutes. The sizzle means it’s getting that deep flavor. Drain off excess fat.
2. Add the onion and garlic to the skillet. Cook until softened, about 3 minutes. Stir in paprika, salt, and pepper. This easy beef and potato casserole starts building layers of flavor right here.
3. In a small bowl, whisk together the cream of mushroom soup and milk until smooth. Set aside.
4. Grease a 9×13-inch baking dish. Layer half the potato slices on the bottom, overlapping slightly. Spread the beef mixture evenly over the potatoes. Pour half the soup mixture over the beef.
5. Layer the remaining potato slices on top. Pour the rest of the soup mixture over everything. Sprinkle with shredded cheddar cheese. Cover with foil and bake for 25 minutes. The smell filling your kitchen is the first sign it’s working.
6. Remove foil and bake another 10-15 minutes, until the cheese is bubbly and golden, and the potatoes are tender when pierced with a fork. Let rest 5 minutes before serving. This easy beef and potato casserole needs that little rest to set up.

Tips and Variations for This Easy Beef and Potato Casserole

• Make ahead: Assemble the casserole up to the baking step, cover, and refrigerate for up to 24 hours. Add 10 minutes to the covered bake time.
• Storage: Leftovers keep in the fridge for 3-4 days. Reheat in the microwave or a 350°F oven until hot.
• Variation: Swap the cream of mushroom for cream of chicken soup. Or add a handful of frozen peas between the layers for a pop of green.
• Serving suggestion: A simple green salad with lemon vinaigrette cuts through the richness perfectly. For more hearty ideas, check out Cozy Creamy Cowboy Soup with Ground Beef — 45-Minute Weeknight Wonder.
