Slow Cooker Beef and Potatoes Casserole

Slow Cooker Beef and Potatoes Casserole is the ultimate one-pot comfort meal, tender ground beef, thin-sliced potatoes, and melted cheese layered together in a creamy, seasoned sauce. It’s a cozy, filling casserole that’s perfect for busy weeknights or cold-weather weekends. The slow cooker does all the work, transforming basic ingredients into a hearty dish full of flavor with little effort. No need to brown the beef separately or pre-cook the potatoes, just layer everything in the crockpot and let it simmer into cheesy, savory perfection.

Ingredients

  • 1½ pounds lean ground beef
  • 1 small onion, finely chopped
  • 3 cloves garlic, minced
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 1 teaspoon paprika
  • 1 teaspoon dried parsley
  • ½ teaspoon onion powder
  • ½ teaspoon garlic powder
  • ¼ teaspoon crushed red pepper flakes (optional)
  • 5 cups thinly sliced russet potatoes (about 4 medium potatoes)
  • 1 can (10.5 oz) cream of mushroom soup
  • 1 cup sour cream
  • ½ cup milk
  • 2 cups shredded cheddar cheese, divided
  • Nonstick spray or butter for greasing slow cooker
  • Chopped fresh parsley or green onions for garnish (optional)

Preparation

Step 1: Lightly grease the inside of a 6-quart slow cooker with nonstick spray or butter.

Step 2: In a medium bowl, mix the ground beef, chopped onion, minced garlic, salt, pepper, paprika, parsley, onion powder, and garlic powder. No need to pre-cook the beef; it will cook thoroughly in the slow cooker.

Step 3: In another bowl, whisk together the cream of mushroom soup, sour cream, and milk until smooth and well combined.

Step 4: Arrange a layer of sliced potatoes on the bottom of the slow cooker. Spoon and spread a portion of the ground beef mixture over the potatoes. Drizzle with a few spoonfuls of the creamy soup mixture and sprinkle with some shredded cheddar cheese.

Step 5: Repeat the layers, potatoes, beef, creamy sauce, cheese, until all ingredients are used up, finishing with a generous layer of cheese on top.

Step 6: Cover and cook on low for 6–7 hours or on high for 3½–4 hours, until the potatoes are tender and the casserole is bubbly.

Step 7: Turn off the heat and let the casserole rest for 10 minutes before serving. Garnish with fresh chopped parsley or green onions if desired.

Variation

  • Use ground turkey or ground chicken as a leaner alternative to beef.
  • Add a layer of frozen mixed vegetables or sliced mushrooms for more texture and nutrients.
  • Swap the cream of mushroom soup for cream of chicken or cream of cheddar for a different flavor profile.
  • Try pepper jack or mozzarella cheese instead of cheddar for a new cheesy twist.
  • For a smoky flavor, add ½ teaspoon liquid smoke or a dash of smoked paprika.

Cooking Note

Thinly slicing the potatoes is key to even, thorough cooking in the slow cooker. Use a mandoline slicer or a sharp knife to get uniform pieces. If you prefer a crispier top layer, transfer the finished casserole to an oven-safe dish and broil for 2–3 minutes to brown the cheese. Always let the casserole sit for a few minutes after cooking to thicken slightly and make serving easier.

Serving Suggestions

This casserole is a full meal on its own, but it pairs well with simple sides like steamed green beans, buttered corn, or a fresh green salad. For a heartier dinner, serve with a slice of crusty bread or warm dinner rolls. It also makes great leftovers, just reheat in the microwave or oven for a quick, satisfying lunch the next day.

Tips

  • Don’t skip greasing the crockpot, it prevents sticking and makes cleanup easier.
  • You can layer raw or lightly browned beef; if using fattier beef, consider browning and draining excess fat first.
  • Avoid lifting the lid during cooking, it slows the process by releasing heat.
  • For a creamier texture, use heavy cream instead of milk.
  • Shred cheese from a block for better melting and less oil compared to pre-shredded bags.
