  • 1 pound ground Italian sausage – spicy or sweet, based on your preference

  • 1 small onion, diced – sweet or yellow onion works best

  • 3 (14-ounce) jars pizza sauce – or about 5 1/4 cups of your favorite sauce

  • 1 tablespoon olive oil – optional, for sautéing

  • Cooking spray – to prevent sticking

Step-by-Step Directions

Let’s walk through the process of making this pizza casserole in your Crock Pot from start to finish.

Stage 1: Cook the Pasta

  1. Bring a large pot of salted water to a boil.

  2. Add rigatoni pasta and cook according to package directions until just al dente.

  3. Drain immediately and toss lightly with olive oil to prevent sticking.

  4. Set aside to cool while you prepare the meat mixture.

Tip: Don’t overcook the pasta since it will continue to cook slightly in the Crock Pot.

Stage 2: Prepare the Meat Sauce

  1. Heat a large skillet over medium-high heat.

  2. Add ground beef and ground Italian sausage, breaking them up with a wooden spoon.

  3. Cook until browned and no longer pink, about 7–8 minutes.

  4. Add diced onion and sauté until softened, about 3–4 minutes.

  5. Stir in minced garlic and cook for another 30 seconds until fragrant.

  6. Add pepperoni slices and stir them in to combine.

  7. Turn off heat and drain excess grease from the meat mixture.

Stage 3: Mix Sauce and Combine

  1. Transfer the cooked meat mixture to a large mixing bowl.

  2. Pour in all three jars of pizza sauce and stir until well combined.

  3. Fold in the cooked rigatoni pasta until it’s fully coated with the meat sauce.

Stage 4: Layer in the Crock Pot

  1. Spray a 6-quart or larger Crock Pot with non-stick cooking spray.

  2. Spread half of the meat and pasta mixture evenly in the bottom of the Crock Pot.

  3. Sprinkle half of the shredded mozzarella cheese over the top.

  4. Add the remaining pasta mixture and top with the rest of the cheese.

  5. (Optional) Top with additional pepperoni slices for presentation and added flavor.

Stage 5: Slow Cook

  1. Cover the Crock Pot and cook on LOW for 3–4 hours or until the cheese is melted and bubbling around the edges.

  2. Avoid opening the lid during the cooking time unless absolutely necessary, as it will release valuable heat.

Stage 6: Serve and Enjoy

  1. Once done, turn off the Crock Pot and let the casserole rest for 5–10 minutes.

  2. Spoon generous portions onto plates or bowls.

  3. Garnish with chopped fresh parsley for a pop of color.

  4. Pair with a side salad or garlic bread, and enjoy!

Tips and Tricks for Perfect Crock Pot Pizza Casserole

1. Use Quality Sauce

The sauce is one of the key flavor components. Use a good-quality pizza or marinara sauce for the best result. Feel free to make your own if you have a favorite homemade version.

2. Add More Toppings

You can add mushrooms, olives, green peppers, or even pineapple to mimic your favorite pizza toppings. Just sauté them with the meat mixture or layer them before the cheese.

3. Avoid Overcooking

While Crock Pots are forgiving, overcooking can make pasta mushy. Stick to the recommended low setting for 3–4 hours.

4. Cheese Choices

Try a blend of mozzarella, provolone, and Parmesan for a deeper cheesy flavor. Freshly shredded cheese melts smoother than pre-shredded.

5. Make it Vegetarian

Swap the meats for sautéed mushrooms, zucchini, and bell peppers. Use vegetarian sausage crumbles for added protein.

6. Make-Ahead Instructions

  • Assemble the casserole up to a day ahead and store in the fridge.

  • You can also freeze individual portions after cooking for up to 3 months.

7. Reheating

Reheat leftovers in the microwave or oven. Avoid reheating in the Crock Pot as it may dry out the casserole.

What to Serve With Crock Pot Pizza Casserole

This dish is rich and filling, but pairs beautifully with lighter sides. Here are a few ideas:

  • Caesar or garden salad

  • Steamed green beans or broccoli

  • Roasted Brussels sprouts

  • A chilled glass of iced tea or red wine

FAQs

Can I use a different pasta?

Can I make this spicier?

Yes! Let it cool completely, then freeze in individual airtight containers. Thaw overnight and reheat in the oven or microwave.
