Exact Ingredients List
Here’s what you’ll need to make this yummy Crockpot pizza casserole:
- 16 oz rigatoni pasta
- 1 tablespoon olive oil
- 1 pound ground beef
- 1 small onion, diced
- 1 bell pepper, diced
- 1/2 teaspoon garlic powder
- 1/2 teaspoon dried oregano
- 1/2 teaspoon dried basil
You’ll also want to grab these items:
- 1/4 teaspoon crushed red pepper flakes (skip if you don’t like heat)
- Salt and pepper to taste
- 3 cups pizza sauce
- 1 can (14 oz) diced tomatoes, drained
- 1 package (6 oz) pepperoni slices
- 3 cups shredded mozzarella cheese
For extra cheesiness, add:
- 1 cup shredded cheddar cheese
Make sure you have all these ingredients before you start cooking. It’s always a good idea to check your pantry and fridge first!

Instructions
Cook the pasta until it’s al dente, about 2 minutes less than the package says. Drain and set aside.
Brown the ground beef with onions and peppers in a skillet. Add spices and cook for another minute or two.
Spray your Crockpot with cooking spray. Layer ingredients in this order:
- Half the pasta
- Half the meat mixture
- Half the sauce and tomatoes
- Half the pepperoni
- Half the cheese
Repeat the layers with remaining ingredients.
Set your Crockpot to low and cook for 3-4 hours. The cheese should be melted and bubbly when it’s done.
Don’t overcook, or your pasta might get mushy. Once everything is hot and the cheese is gooey, it’s ready to serve!
You can customize this recipe by adding your favorite pizza toppings. Try mushrooms, olives, or sausage for extra flavor.

Remember, cooking times may vary slightly with different ingredients, so keep an eye on your casserole.

Tips, Tricks & Storing
Cook the pasta slightly less than usual to prevent it from getting mushy in the slow cooker. Aim for about 2 minutes less than the package directions suggest.
For extra flavor, try using Italian sausage instead of ground beef. You can also mix in some cooked bacon bits for a smoky twist.
Don’t open the lid too often while cooking. Each time you do, it adds about 15-20 minutes to the cooking time.
To make this dish lower in carbs, swap out the pasta for cauliflower florets. Cook them separately and add them in the last 30 minutes of cooking.
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave or oven until hot throughout.
You can freeze portions for up to 3 months. Thaw overnight in the fridge before reheating.
For a fun twist, serve with garlic bread on the side for dipping. It’s a great way to soak up any extra sauce!
If you like a crispy top, transfer the casserole to a baking dish after cooking. Sprinkle with extra cheese and broil for 2-3 minutes until golden and bubbly.
