Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 1.5 pounds ground beef
• 1 medium onion, finely diced
• 3 garlic cloves, minced
• 1 teaspoon smoked paprika
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 4 to 5 medium potatoes (Yukon Gold or russet), thinly sliced
• 1 cup beef broth
• 1 can (10.5 ounces) cream of mushroom soup
• 1 cup sour cream
• 1 cup shredded cheddar cheese
• 1/2 cup shredded mozzarella cheese

Directions

Start by heating a large skillet over medium heat. Add the ground beef and cook until fully browned, breaking it into small pieces as it cooks. Once the meat is nearly done, add the diced onion and minced garlic. Cook for an additional 2 to 3 minutes until the onion softens and becomes fragrant.

Season the beef mixture with smoked paprika, garlic powder, onion powder, salt, and black pepper. Stir well to evenly distribute the seasoning, then drain any excess fat.

Lightly grease the inside of a slow cooker. Wash and thinly slice the potatoes into even rounds so they cook uniformly.

In a bowl, mix together the cream of mushroom soup, sour cream, and beef broth until smooth and creamy.

Begin layering the casserole in the slow cooker. Spread a thin layer of the sauce on the bottom. Add half of the sliced potatoes, followed by half of the cooked beef mixture. Spoon some sauce over the beef and sprinkle a portion of the cheddar cheese.

Repeat the layers with the remaining potatoes, beef, and sauce. Finish by topping with the remaining cheddar cheese and all of the mozzarella cheese.

Cover and cook on low for 4 to 6 hours or on high for 2 to 3 hours, until the potatoes are soft and fully cooked.

Let the casserole rest for about 10 minutes before serving to allow it to set properly.

Variations

You can replace ground beef with ground turkey for a lighter version. Adding vegetables such as peas, carrots, or bell peppers can increase nutrition and color.

For a spicier version, include chili powder or chopped green chilies in the beef mixture. If you prefer a richer flavor, use a mix of cheddar, mozzarella, and Monterey Jack cheese.

Sweet potatoes can also be used instead of regular potatoes for a slightly sweeter taste and added nutrients.

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Make sure the casserole is fully cooled before storing.

To reheat, place a portion in the microwave and heat for 1 to 2 minutes until warm. You can also reheat it in the oven at 350°F for about 15 minutes for a firmer texture.

For freezing, place cooled portions in airtight containers and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
