This Crock Pot Potato Pizza Casserole is a comforting, flavor-packed meal. Layers of seasoned browned ground beef, sliced potatoes, and an Italian-style tomato-cheese sauce topped with melted cheese make it a family favorite.
This Potato Pizza Bake recipe comes from an old-fashioned, handwritten collection that I’ve used for more than 25 years. I first tried it at a childhood friend’s house shortly after getting married, and it quickly became a go-to for busy weeknights and relaxed weekend dinners alike.
You can prepare it the traditional way in the oven at 375°F for about an hour, or set it and forget it in the crockpot so your home fills with delicious aromas all day. I personally prefer the slow-cooker method for its convenience and the way the flavors meld over a long, gentle cook.
How to Make Potato Pizza Bake in the Crockpot
Ingredients needed for this potato pizza casserole recipe:
In addition to 1 1/2 pounds ground beef (not pictured), you’ll need the following ingredients:
- 4 cups thinly sliced potatoes (Russet or Yukon Gold work well)
- 1 medium onion, diced
- 1 can cheddar cheese soup
- 1 15-ounce can tomato sauce
- 1 soup can of milk (use the empty soup can to measure)
- 1/2 cup shredded Parmesan cheese (or 1/2 cup dried)
- 6 slices mozzarella cheese
- 1 teaspoon salt
- 1/8 teaspoon black pepper
- 1 teaspoon sugar
- 1/2 teaspoon oregano
1. Layer the potatoes and onion in the bottom of the crockpot.
Use thin, even slices so the potatoes cook through during the slow-cooking time. Arrange the onion evenly over the potatoes for a balanced flavor throughout the dish.
2. Brown and drain the ground beef, then layer it over the potatoes.
Cook the beef until no longer pink, drain excess fat, and spread it in an even layer over the vegetables. Season the meat lightly as it cooks to build extra flavor.
3. Mix and pour the sauce over the layers: soup, tomato sauce, milk, and spices.
In a bowl, combine the cheddar cheese soup, tomato sauce, measured milk, sugar, salt, pepper, and oregano. Stir until smooth, then pour the mixture evenly over the layered potatoes and beef.
4. Cover and cook on low for 8 hours or high for 4 hours.
For best results, cook on low for 8 hours to allow the flavors to fully develop and the potatoes to become tender without breaking down. If you’re short on time, cook on high for about 4 hours. I often start on high until it’s bubbly, then switch to low until dinner.
5. Add cheeses and finish before serving.
Once the casserole is cooked, sprinkle the Parmesan over the top and arrange the mozzarella slices across the surface. Replace the lid and let the cheese melt for a few minutes. If you prefer a browned top, you can transfer the crockpot insert to a preheated oven under the broiler for 2–3 minutes—watch closely to prevent burning.
If you want to amplify the inviting aroma, set your bread machine to finish just as dinner is ready and serve warm homemade bread alongside the casserole. Add a simple green salad for a complete, satisfying meal.
Tips, Variations, and Storage
- Substitutions: If you don’t have cheddar cheese soup, a can of cream soup (cheddar or mushroom) or a simple homemade white sauce can work. Adjust seasonings to taste.
- Potato type: Yukon Gold gives a creamier texture; Russet holds its shape well. Slice evenly for even cooking.
- Add-ins: Bell peppers, sliced mushrooms, or cooked sausage can be layered with the beef for extra flavor.
- Make-ahead: Assemble in the crockpot insert the night before, refrigerate, and cook the next day. Allow extra cook time if the ingredients go into the cooker straight from the fridge.
- Leftovers: Store covered in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through.
- Yield: This recipe serves about 10–12 people as originally noted—great for family dinners or small gatherings.
