Crock Pot Pizza Casserole vs. Traditional Baked Pizza Casserole
If you’re torn between making a baked pizza casserole or using your slow cooker, here’s how they stack up:
Crock Pot Pizza Casserole
- Hands-Off Cooking: Just layer the ingredients and let the slow cooker do the work—no need to babysit the oven.
- Moist and Saucy: The slow cooker locks in moisture, making this version extra gooey and flavorful.
- Great for Make-Ahead: Start it earlier in the day and have dinner ready when you are—perfect for busy weekdays.
- Flexible Timing: Cooks on low for several hours, which gives you wiggle room with your schedule.
Traditional Baked Pizza Casserole
- Faster Overall: Typically ready in under an hour from start to finish.
- Crispier Edges: The oven can give you those crispy cheese edges and more texture.
- Last-Minute Friendly: Ideal if you forgot to plan ahead but still want a hearty dinner.
- More Browning: Baking allows toppings and cheese to brown and bubble for that classic pizza appeal.
Bottom Line:
Use the crock pot when you want a set-it-and-forget-it dinner that’s cozy and comforting. Choose the baked method when you’re short on time and craving a slightly crispier bite.
What Is This Casserole Exactly?

It’s perfect for feeding a crowd or meal-prepping for the week, and you can totally customize the toppings to match your favorite pizza combos.

FAQ
Can I use ground beef instead of sausage?
Absolutely! You can sub in ground beef or even ground turkey. Just make sure to season it well and cook it fully before layering.
What pasta works best?
Rotini, penne, or elbow pasta all work great. Just be sure to cook it slightly underdone to avoid mushy noodles.
Can I make this vegetarian?
Yes! Just skip the sausage and pepperoni and add veggies like mushrooms, spinach, and olives.
Do I need to cook the pasta first?
Yes, partially cook the pasta (about 2 minutes shy of al dente) so it finishes cooking perfectly in the slow cooker without turning too soft.
How spicy is it?
Totally up to you! Skip the crushed red pepper and use mild sausage for a tame version, or amp it up with hot sausage and extra red pepper flakes.
Can I bake this in the oven instead?
Sure! Assemble in a casserole dish and bake covered at 350°F for about 30–35 minutes, uncover for the last 10 to let the cheese get bubbly and golden.
Low-Carb or Gluten-Free Swaps
Looking to lighten things up or avoid gluten? You can easily swap the pasta for cooked spaghetti squash, zucchini noodles, or your favorite gluten-free rotini. Just reduce the cook time slightly if using cooked veggies to prevent mushiness.
Budget-Friendly Tips
This recipe is already a money-saver, but here are a few ways to stretch it even further! Use store-brand pasta sauce and shredded cheese, and look for family packs of Italian sausage or ground beef. Got leftover deli meats like pepperoni or ham? Toss them in—nothing goes to waste!
How to Reheat Without Drying Out
The key to reheating this casserole is moisture. For the microwave, cover your serving with a damp paper towel and heat in 30-second bursts. In the oven, cover with foil and bake at 325°F for 15–20 minutes. Want a little crisp? Air fry at 350°F for 5–6 minutes.
Turn It Into a Freezer Meal Kit
To make this ahead, cook your meat and mix it with the sauce and seasonings. Freeze the meat mixture in one bag, the cheese in another, and the uncooked pasta in a third (or include a box of it). When ready to cook, just thaw, layer in your crockpot, and go!
Why the Crock Pot is Perfect for Pasta-Based Dishes
Slow cookers are a game-changer for pasta casseroles. They gently meld all the flavors together and keep everything tender without drying out like the oven sometimes can. Plus, you can set it and forget it—no need to babysit boiling water or preheat an oven!
Make It a Party Hit (Tips for Doubling the Recipe)
Feeding a crowd? This recipe doubles beautifully—just layer it into a large 7 or 8-quart slow cooker. You can even prepare two smaller batches in separate slow cookers if needed. Want a little DIY fun? Set out small bowls of extra toppings (more cheese, pepperoni, olives) and let guests customize their bowls before serving!
Final Thoughts
If you love pizza and pasta (and who doesn’t?), this Slow Cooker Pizza Casserole will be your new weeknight staple. It’s hearty, full of flavor, and endlessly customizable. Best of all, you just layer and let the slow cooker do the work. Whether you’re serving picky eaters or feeding a party crowd, this one’s a guaranteed win. Load it up, plug it in, and enjoy the smell of dinner coming together while you relax.

Slow Cooker Pizza Casserole
Ingredients
- 12 ounces pasta elbow or rotini, cooked until almost al dente
- 1 table olive oil
- 1 pound Italian sausage mild or hot
- 1 cup yellow onion diced
- 3 cloves garlic minced
- 28 ounces of pizza sauce
- 1/2 teaspoon crushed red pepper flakes
- 1 teaspoon Italian seasoning
- 1/2 teaspoon smoked paprika
- 1 green bell pepper chopped
- 1 red bell pepper chopped
- 2 cups shredded mozzarella cheese
- 1 cup shredded provolone cheese
- 1/2 cup pepperoni
Instructions
- Cook the pasta according to the package directions but remove it slightly before al dente, about 2 minutes, so the pasta is slightly underdone.
- Heat the olive oil in a large skillet over medium heat. Add the Italian sausage and brown on both sides, breaking it up into smaller pieces. In the last 3 minutes add the onions until they soften slightly. Then add in the garlic at the last minute. The sausage does not need to be fully cooked.
- Add the red pepper flakes, Italian seasoning and smoked paprika to the pizza sauce and stir until combined. Pour about a third of the sauce to the bottom of the slow cooker, spreading it out evenly.
- Next add about a third of the pasta over the sauce, then add a third of the sausage and onions. Sprinkle about a third of the red and green peppers over the sausage.
- Next add a third of the mozzarella and provolone cheeses, followed by some pepperoni layered over the top. Continue the same steps 2 more times until you are out of ingredients.
- Secure the slow cooker lid and cook for 2 hours on high or 3-4 hours on low. The cheese will be really melted and bubbly. Serve and enjoy.
