🕒 Prep Time: 15 minutes | Cook Time: 3–4 hours (low) | Total Time: 3 hrs 15 min
Ingredients
- 1 lb ground beef (or Italian sausage, crumbled)
- 1 medium onion, diced
- 2 cloves garlic, minced
- 1 jar (24 oz) marinara or pizza sauce
- 1 can (15 oz) diced tomatoes, drained
- 2 tsp Italian seasoning
- 12 oz rotini or penne pasta (uncooked)
- 2 cups shredded mozzarella cheese
- 1 cup shredded cheddar cheese
- 1 cup sliced pepperoni
- 1 bell pepper, diced (optional)
- 1 cup sliced mushrooms (optional)
- 1/2 cup black olives, sliced
- 2 tbsp olive oil
- Salt & pepper to taste
- Fresh basil or parsley, for garnish
Step-by-Step Instructions
- Brown the Meat:
In a large skillet, heat olive oil over medium-high. Add ground beef (or sausage), onion, and garlic. Cook until browned and fragrant. Season lightly with salt and pepper. Drain excess fat. - Build the Sauce:
Add marinara sauce, diced tomatoes, and Italian seasoning to the skillet. Stir everything together to create a rich, pizza-style sauce. Let it simmer for 3–5 minutes. - Layer in the Crock Pot:
Spray the slow cooker with nonstick spray. Spread a thin layer of sauce on the bottom, then add half the uncooked pasta. Top with more sauce, a sprinkle of mozzarella, and a few slices of pepperoni. Repeat the layers until all ingredients are used, finishing with cheese on top. - Customize with Toppings:
Add your favorite pizza toppings — bell peppers, mushrooms, and olives. This step makes the casserole feel like a true “supreme pizza” in casserole form. - Slow Cook:
Cover and cook on low for 3–4 hours (or high for 2 hours). The pasta will absorb the sauce and become tender while the cheese melts into gooey perfection. - Final Melt:
During the last 10 minutes, sprinkle the remaining mozzarella and cheddar over the top. Cover again until melted. - Serve & Garnish:
Scoop into bowls or plates, garnish with fresh basil or parsley, and serve with garlic breadsticks for the ultimate pizza night!
Pro Tips for Success
- Pasta Trick: Keep pasta slightly undercooked if boiling ahead — it will continue cooking in the sauce.
- Make It Healthier: Swap ground beef for ground turkey or chicken, and use whole wheat or gluten-free pasta.
- Storage & Meal Prep: Store leftovers in an airtight container for up to 4 days. It reheats beautifully in the microwave or oven.
