Ingredients
Core Ingredients
1 pound rigatoni pasta, or penne, rotini, or ziti
1 pound lean ground beef
1 pound ground Italian sausage, sweet or spicy
1 small sweet onion, diced
4 cloves garlic, minced
3 jars (14 ounces each) pizza sauce, about 42 ounces total
16 ounces shredded mozzarella cheese, about 4 cups
1 package (3.5 to 8 ounces) sliced pepperoni
Seasonings & Optional Add-ins
2 teaspoons Italian seasoning
Salt and black pepper, to taste
Chopped fresh parsley or basil, optional for garnish
Instructions
Cook the Meat
Heat a large skillet over medium-high heat. Add the ground beef and Italian sausage and cook for about 7–10 minutes, breaking the meat apart with a wooden spoon as it cooks.
Continue cooking until the beef and sausage are browned and no longer pink. Drain excess grease carefully, then return the meat to the skillet.
Add the Onion and Garlic
Add the diced sweet onion to the cooked meat and sauté for about 3–4 minutes, until it begins to soften.
Stir in the minced garlic and cook for another 30–60 seconds, just until fragrant. Be careful not to burn the garlic.
Season the meat mixture with Italian seasoning, along with a small amount of salt and black pepper.
Prepare the Pasta
Cook the rigatoni in a large pot of salted water according to the package directions, but stop cooking about 2 minutes before the recommended time. The pasta should remain slightly firm because it will continue cooking in the Crock Pot.
Drain the pasta well. Avoid overcooking it at this stage, as fully cooked pasta can become too soft during slow cooking.
Layer the Casserole
Lightly grease the inside of a large Crock Pot or slow cooker.
Add a layer of the cooked pasta, followed by some of the cooked beef and sausage mixture, pizza sauce, mozzarella, and pepperoni.
Continue layering until the ingredients are used. Try to finish with a generous layer of mozzarella and pepperoni on top.
Slow Cook
Cover the Crock Pot with the lid and cook on Low for approximately 3–4 hours.
Because slow cookers vary in temperature, begin checking the casserole around the 3-hour mark. The casserole is ready when the cheese is fully melted, the sauce is hot and bubbling around the edges, and the pasta is tender but not mushy.
Avoid cooking much longer than necessary because the pasta can become overly soft.
Finish and Serve
Turn off the slow cooker and allow the casserole to rest uncovered for about 5–10 minutes. This gives the sauce time to settle and makes the casserole easier to serve.
Garnish with chopped fresh parsley or basil if desired. Serve hot with garlic bread, a green salad, or your favorite pizza-style side.
Tips
Do Not Overcook the Pasta
Cooking the pasta slightly less than package directions is one of the most important steps. It gives the pasta enough structure to hold up during slow cooking.
Brown the Meat First
Always brown the beef and sausage before adding them to the Crock Pot. This improves the flavor and allows excess grease to be removed before assembling the casserole.
Use Plenty of Sauce
The pasta absorbs some of the sauce as it cooks. Using the full amount of pizza sauce helps keep the casserole moist and flavorful.
Layer the Cheese
Adding mozzarella throughout the casserole ensures that every serving gets plenty of melted, cheesy goodness instead of leaving all the cheese on the top.
Do Not Keep Opening the Lid
Try to keep the Crock Pot covered while cooking. Each time the lid is removed, heat escapes and the cooking process can be delayed.
Watch the Cooking Time
Slow cookers can vary significantly. Check the casserole near the lower end of the cooking time and stop cooking once the pasta is tender and the cheese is melted.
Let It Rest Before Serving
A short resting period helps the casserole thicken slightly, making it easier to scoop and serve without becoming runny.
Use a Nonstick Liner if Desired
A slow cooker liner can make cleanup much easier, especially when working with a cheesy tomato-based casserole.
Variations
Make It Spicy
Use spicy Italian sausage, spicy pepperoni, or add crushed red pepper flakes to the meat mixture for extra heat.
Add More Pizza Toppings
Stir in sliced mushrooms, diced bell peppers, black olives, banana peppers, or jalapeños. Cook vegetables that release a lot of moisture briefly before adding them.
Try Different Cheese
Mozzarella is classic, but you can add provolone, Parmesan, cheddar, or a pizza cheese blend for additional flavor.
Use Turkey or Chicken
Ground turkey or ground chicken can replace the ground beef. Pair them with chicken Italian sausage or turkey sausage for a lighter variation.
Make a Supreme Pizza Version
Add mushrooms, bell peppers, onions, olives, and pepperoni to create a slow cooker casserole inspired by a supreme pizza.
Use Different Pasta Shapes
Rigatoni works especially well because its ridges hold onto the sauce, but penne, rotini, ziti, or another short pasta can also be used.
Add Fresh Herbs
Fresh basil, parsley, or oregano added just before serving gives the rich casserole a fresh finish.
Make Individual Portions
Spoon the finished casserole into oven-safe bowls and top with extra mozzarella and pepperoni. Broil briefly until the cheese bubbles for a restaurant-style presentation.
Q&A
Can I put uncooked pasta directly into the Crock Pot?
For this recipe, partially cooking the pasta first is recommended. It helps prevent the pasta from becoming unevenly cooked or absorbing too much liquid.
Can I make this casserole ahead of time?
Yes. The meat mixture can be cooked ahead and refrigerated. You can also assemble the ingredients before cooking, then refrigerate the prepared components until you are ready to cook.
Can I use a different type of pasta?
Yes. Penne, rotini, ziti, or other short pasta shapes are good substitutes for rigatoni.
Can I use only ground beef?
Yes. You can replace the Italian sausage with additional ground beef, although the casserole will have a less pronounced Italian sausage flavor.
How do I store leftovers?
Allow the casserole to cool, then transfer it to an airtight container and refrigerate for up to 3–4 days.
Can I freeze Crock Pot Pizza Casserole?
Yes. Portion the cooled casserole into freezer-safe containers and freeze. Thaw it in the refrigerator before reheating for the best texture.
How do I reheat leftovers?
Reheat individual portions in the microwave until hot, or warm larger portions gently in a covered oven-safe dish. Add a little extra pizza sauce if the pasta has absorbed too much moisture.
What should I serve with pizza casserole?
Garlic bread, breadsticks, Caesar salad, roasted vegetables, or a simple green salad all make excellent sides.
