Ingredients

• 1 pound ground beef
• 1 small onion, diced
• 2 cups diced potatoes
• 1 can condensed cream of mushroom soup
• 1 cup beef broth
• 1 cup shredded cheddar cheese
• 1 teaspoon garlic powder
• ½ teaspoon paprika
• Salt and black pepper, to taste

How to Make Slow Cooker Casserole

1. Brown the Beef

Heat a large skillet over medium heat. Add the ground beef and diced onion.

Cook until the beef is browned and the onion is softened. Drain excess grease.

2. Layer the Ingredients

Place the diced potatoes in the bottom of the slow cooker.

Add the browned beef and onion mixture.

In a bowl, stir together the cream of mushroom soup, beef broth, garlic powder, paprika, salt, and black pepper. Pour the mixture over the beef and potatoes.

3. Slow Cook

Cover and cook on LOW for 5–6 hours or HIGH for 2½–3½ hours, until the potatoes are tender and the casserole is hot throughout.

4. Add the Cheese

Sprinkle the shredded cheddar cheese over the top during the final 15–20 minutes of cooking.

Cover again and allow the cheese to melt completely.

5. Serve

Spoon the hot casserole into rustic bowls and serve immediately.

For extra flavor, garnish with sliced green onions or a little freshly ground black pepper.

Tips for the Best Slow Cooker Casserole

Cut the potatoes into evenly sized pieces so they cook at the same rate.

Browning the ground beef first gives the casserole better flavor and prevents excess grease from collecting in the slow cooker.

Keep the lid closed as much as possible while cooking. Frequent opening allows heat to escape and can extend the cooking time.

For a creamier casserole, stir gently just before serving to combine the sauce with the potatoes and beef.

Easy Variations

You can add frozen peas, corn, carrots, mushrooms, or green beans for extra vegetables.

Ground turkey can replace the beef for a lighter variation.

Try Monterey Jack or Colby cheese instead of cheddar for a different flavor.

What to Serve With Slow Cooker Casserole

This hearty casserole can be served on its own, but it also pairs nicely with green salad, steamed vegetables, dinner rolls, cornbread, or roasted broccoli.

A warm crusty roll is perfect for soaking up the creamy sauce.

How to Store Leftovers

Transfer cooled leftovers to an airtight container and refrigerate for up to 3–4 days.

Reheat individual portions in the microwave or warm gently in a covered skillet.

If the casserole becomes dry after refrigeration, add a small splash of beef broth before reheating.

Frequently Asked Questions
