How to Make Slow-Cooker Pizza Casserole
Cook the Pasta: Begin by boiling the rigatoni according to the package instructions until al dente. Once cooked, drain the pasta and set it aside to cool slightly.
Sauté the Meat: In a skillet, brown the ground beef along with the chopped onion over medium heat. Cook until the meat is no longer pink and the onions are translucent. Drain any excess fat for a healthier dish.
Combine Ingredients: In your trusty 5-quart slow cooker, mix together the drained pasta, beef mixture, shredded mozzarella cheese, pizza sauce, cream of mushroom soup, and sliced pepperoni. Stir until all ingredients are well combined.
Slow Cook: Cover the slow cooker and set it to low. Let it cook for 2-3 hours, or until everything is heated through and the flavors meld beautifully.
Serve and Garnish: Once done, serve warm and top with freshly chopped basil or arugula for that burst of freshness!
Optional: Add crushed red pepper flakes for a spicy kick!

How to Store and Freeze Slow-Cooker Pizza Casserole
- Fridge: Store leftovers in airtight containers for up to 4 days. Make sure to let the casserole cool completely before sealing to maintain freshness.
- Freezer: For longer storage, freeze in containers for up to 3 months. Leave space at the top of the container, as the casserole may expand when frozen.
- Reheating: Reheat in the oven at 350°F (175°C) for about 20-25 minutes, or in the microwave until heated through. Adding a splash of water can help maintain moisture.
- Thawing: When ready to enjoy, thaw in the fridge overnight before reheating for best results. The Slow-Cooker Pizza Casserole will still be delicious and comforting!
Expert Tips for Slow-Cooker Pizza Casserole
Cook Pasta Al Dente: Ensure the rigatoni is cooked just until al dente before mixing. Overcooking the pasta can make it mushy in the slow cooker.
Brown the Meat Well: Sauté the beef and onion until fully browned to develop rich flavors. Undercooked meat may lead to an unappetizing texture.
Preheat Your Slow Cooker: For best results, preheat your slow cooker for about 15 minutes before adding the ingredients. This reduces total cooking time and enhances flavor blending.
Adjust Liquids as Needed: If using a larger slow cooker, consider reducing the cooking liquid slightly to prevent excess moisture in your Slow-Cooker Pizza Casserole.
Garnish for Freshness: Add freshly chopped basil or arugula just before serving to elevate the dish with a fresh burst of flavor and color.

Coleslaw: A tangy coleslaw brings a refreshing crunch, enhancing the comfort food experience with its crisp texture and zesty flavor.
