Ingredients You’ll Need
To make this delicious pizza casserole, gather these simple ingredients:
- 1 pound rigatoni pasta
- 1 pound lean ground beef
- 1 pound ground Italian sausage (sweet or spicy)
- 1 small sweet onion, diced
- 1 (3.5-ounce) package pepperoni slices
- 4 cloves garlic, minced
- 3 (14-ounce) jars pizza sauce
- 16-ounce bag shredded mozzarella cheese
- Chopped parsley, for garnish (optional)

Step-by-Step Instructions
1. Cook the Pasta
Start by boiling the rigatoni pasta according to the package instructions until al dente. Drain and set aside. The pasta will continue to cook in the slow cooker, so slightly undercooking it is best to prevent mushiness.
2. Brown the Meats
In a large skillet over medium heat, sauté the diced onion until translucent (about 3-4 minutes). Add the ground beef and Italian sausage, breaking them up as they cook. Cook until fully browned and no longer pink. Drain any excess fat.
3. Sauté the Garlic
Add the minced garlic to the meat mixture and cook for an additional minute until fragrant. Stir well to distribute the flavors.
4. Combine with Sauce
Pour in the pizza sauce and stir, ensuring the meat mixture is evenly coated. Let it simmer for a couple of minutes to absorb the flavors.
5. Layer the Casserole
In a 6-quart slow cooker, layer as follows:
- Half of the cooked rigatoni
- Half of the meat sauce mixture
- Half of the pepperoni slices
- Half of the shredded mozzarella cheese
Repeat the layers with the remaining ingredients.
6. Cook in the Crock Pot
Cover the slow cooker and cook on low for 2-3 hours, or until the cheese is melted and bubbly.
7. Garnish and Serve
Once cooked, garnish with chopped parsley if desired. Serve warm and enjoy!
Tips for the Best Crock Pot Pizza Casserole

- Cheese Variations: Try a mix of mozzarella, provolone, and Parmesan for a richer cheese pull.
