Ingredients
- Penne Pasta: Regular penne, whole wheat, and gluten-free would all work well for this pizza casserole in the Crock Pot. You could also use rotini noodles or another pasta shape. Be sure to only cook them to al dente.
- Lean Ground Beef: Lean ground beef (either 90/10 or 85/15) is best for this recipe so that it’s not too greasy. You’ll drain it before adding it to the casserole.
- Yellow Onion and Minced Garlic: Fresh onion and garlic add tons of savory flavor to this dish.
- Marinara Sauce: You’re going to add two jars of marinara sauce to this pizza crockpot casserole. It gives the dish classic tomato flavor.
- Diced Tomatoes: You can use regular or fire-roasted tomatoes. They’re flavorful, but not too spicy.
- Italian Seasoning: The blend of basil, oregano, rosemary, and thyme brings out all the classic pizza flavors. Some Italian seasonings also include garlic powder, parsley, crushed red pepper, or sage.
- Shredded Mozzarella Cheese: Mozzarella is the classic cheese to use on pizza but you could also use creamy cheeses like Parmesan, Provolone, Cheddar, Gouda, Ricotta, Fontina, Gorgonzola, and Gruyere instead.
- Pepperoni: Pepperoni is a sausage made with pork, beef, or turkey seasoned with chili peppers, paprika, garlic, and other spices. You can find mild or spicier versions depending on what you prefer.

Variations
- Add Your Favorite Pizza Toppings: Crunchy cut up green or red bell peppers, mushrooms, and olives go well in this dish.
- Gluten-Free: Look for gluten-free penne to easily make this recipe gluten-free for those who have allergies or sensitivities.
- Change the Sauce: There are so many flavor varieties in marinara sauce. Mix it up with a basil, garlic, or a cheesy variety.
- Use Italian Sausage: Instead of ground beef, swap in Italian sausage for more heat and spice. Or do half beef and half Italian sausage.
- Vegetarian Version: If you want a lighter, meat-free version of the recipe, leave out the ground beef and pepperoni and use more veggies like mushrooms, bell peppers, and any other veggies you like on veggie pizza.
How to Make Pizza Casserole in the Crock Pot
Making Crock Pot Pizza Casserole from scratch is easier than you might think! Here’s how to do it in just 6 simple steps.
- Step 1: Cook the Pasta. Cook the penne pasta to al dente using the directions on the package. Drain and set it aside.
- Step 2: Cook the Beef and Onions. Add the ground beef and sliced onion to a large skillet. Cook over high heat until the meat is browned and the onions are soft. Drain any excess grease.
- Step 3: Get the Sauce Ready in the Slow Cooker. I recommend using a 6-quart slow cooker. Add the marinara sauce, diced tomatoes, garlic, Italian seasoning, and black pepper. Mix everything together.
- Step 4: Add Everything In. Put in the pasta, ground beef mixture, 1 cup of mozzarella cheese, and pepperoni. Mix well.
- Step 5: Cover and Cook. Cook on low for 3-4 hours. When the pizza casserole is done cooking, top with the remaining cheese and let it cook a few more minutes until the cheese has melted.
- Step 6: Serve. Garnish with fresh parsley or parmesan cheese and enjoy!
Hint: Cooking the Pasta
You’ll want to cook the pasta before adding it to the slow cooker and layering in the casserole. But be careful to only boil it to al dente, otherwise it can get soggy in the casserole!
Expert Tips
- Storing and Reheating: Leftovers keep in an airtight container in the fridge for up to 3 days, or frozen for up to 3 months. Reheat the dish in the microwave on medium heat for 30-60 second intervals until it is heated through.
- Nonstick Spray: For an easier cleanup, spray the inside of the Crock Pot with nonstick spray or use a Crock Pot liner.
- Cook on Low: Cooking this dish on high or for longer than 4 hours may cause it to burn. I recommend only using the low setting on your slow cooker for this one.
- Serve Hot: I don’t recommend leaving the Crock Pot on the warm setting for a long time (like if you’re serving this at a party and guests might want to have seconds). The pasta continues to soak up the sauce and this could lead to the pasta becoming mushy.
Serving Suggestions
This Crock Pot Pizza Casserole is a hit with the whole family and makes for a great potluck dish. We also love making this one for meal trains if someone is recovering from an illness or has just had a baby. It’s so simple to make and easy for them to heat up.
- Garnish with fresh chopped parsley for a pop of green color. Serve with garlic bread and a side salad.
- This makes a delicious lunch the next day as the flavors have time to marinate and meld together. Sprinkle some extra parmesan cheese on top when you serve the leftovers.
- If you love spicy pizza, add a little crushed red pepper or a few pepperoncini peppers on top.
- Hosting a crowd? Have Italian night and make this dish along with slow cooker chicken parmesan and meatball soup.

Recipe FAQs
