Ingredients
- 1 pound lean ground beef
- 1 package (16 ounces) rotini pasta
- 1 jar (24 ounces) pizza sauce
- 2 cups shredded mozzarella cheese
- 1 cup sliced pepperoni
Instructions
Step 1: Brown the Ground Beef
Heat a large skillet over medium heat. Add the ground beef and cook until browned, breaking it into small pieces as it cooks.
Drain excess grease thoroughly. Do not add raw ground beef directly to the slow cooker.
Step 2: Prepare the Slow Cooker
Lightly grease the inside of a 6-quart slow cooker.
Spread a small amount of pizza sauce across the bottom to help prevent sticking.
Step 3: Add the Pasta and Sauce
Add the uncooked rotini pasta, browned ground beef, and remaining pizza sauce to the slow cooker.
Pour in 2 cups of water and stir gently until the pasta is evenly coated and mostly covered with liquid.
Step 4: Slow Cook
Cover and cook on HIGH for approximately 2–3 hours or LOW for 4–5 hours.
Cooking time will vary depending on the slow cooker. Stir once or twice during cooking if possible. Check the pasta toward the end and stop cooking when it is tender but still holds its shape.
Step 5: Add the Pepperoni
About 20 minutes before serving, stir in the sliced pepperoni.
Reserve a few slices to arrange over the top if desired.
Step 6: Add the Mozzarella
Sprinkle the shredded mozzarella evenly over the pasta mixture.
Cover and cook for another 10–15 minutes, or until the cheese is melted and bubbly.
Step 7: Serve
Turn off the slow cooker and let the casserole rest for about 5 minutes. Spoon into bowls and serve warm.
Tips for the Best Pizza Pasta Casserole
- Brown the beef first: This improves flavor and helps remove excess grease.
- Use rotini: Its twists hold the sauce beautifully.
- Check the pasta early: Slow cookers vary, and pasta can become mushy if overcooked.
- Keep the pasta covered with liquid: This helps it cook evenly.
- Add cheese near the end: This keeps the mozzarella creamy and prevents it from overcooking.
- Avoid frequent lid lifting: Each time the lid is removed, heat escapes and cooking slows down.
Optional Variations
The five core ingredients create the basic recipe. These optional additions can customize the casserole:
- Supreme pizza style: Add diced bell peppers, mushrooms, or black olives.
- Spicy version: Use spicy pepperoni or add red pepper flakes.
- Extra cheesy: Add a little grated Parmesan before serving.
- Sausage pizza flavor: Replace some or all of the ground beef with Italian sausage.
- Vegetarian option: Omit the beef and pepperoni and add extra vegetables.
What to Serve with Pizza Pasta Casserole
This hearty casserole is delicious on its own, but it also pairs well with:
- Garlic bread
- Caesar salad
- Steamed green beans
- Roasted broccoli
- Fresh garden salad
- Garlic-roasted vegetables
For a family-style dinner, serve the casserole with warm garlic bread and a simple green salad.
Make-Ahead Instructions
For easier preparation, brown the ground beef a day ahead and refrigerate it in an airtight container.
You can also measure the sauce and prepare the pepperoni in advance. For the best pasta texture, combine the ingredients and cook shortly before serving rather than leaving uncooked pasta soaking in sauce overnight.
Storage Instructions
Store leftover casserole in an airtight container in the refrigerator for up to 3–4 days.
To reheat, add a small splash of water or broth and warm gently in the microwave or in a covered saucepan over low heat.
For freezing, cool completely and divide into individual portions. Freeze in airtight containers for up to 2 months. Thaw overnight in the refrigerator before reheating. The pasta may soften slightly after freezing.
Frequently Asked Questions
Can I put uncooked pasta in the slow cooker?
Yes. This recipe is designed for uncooked rotini. The pasta cooks directly in the sauce and added water. Make sure there is enough liquid and check it regularly near the end of cooking.
Do I need to boil the pasta first?
No. The rotini goes directly into the slow cooker, making preparation easier and reducing the number of dishes.
Can I use a different pasta shape?
Yes. Penne, medium shells, or fusilli can work. Cooking times may vary depending on the shape and thickness.
Why is my pasta too soft?
It may have cooked too long. Slow cookers vary, so begin checking the pasta before the suggested cooking time is finished. Switch off the slow cooker as soon as the pasta is tender.
Can I use turkey instead of ground beef?
Yes. Ground turkey is a suitable substitute. Brown it thoroughly before adding it to the slow cooker.
Can I double this recipe?
You can, provided your slow cooker is large enough. Do not fill it beyond its recommended capacity, and check the pasta carefully because a larger batch may cook differently.
