Made with tender rigatoni pasta, seasoned ground beef, rich marinara sauce, and plenty of melted mozzarella cheese, this hearty crockpot pasta recipe delivers all the flavors of a traditional baked pasta dish with much less effort.

What makes this easy slow cooker rigatoni recipe so convenient is that the dry pasta cooks right in the crockpot alongside the beef and tomato sauce.

After a few hours of slow cooking, the rigatoni becomes tender and absorbs the delicious flavors of the sauce, while the melted mozzarella creates a wonderfully cheesy finish.

Ingredients

• 1 pound dry rigatoni pasta
• 1 pound ground beef
• 1 jar (24 ounces) marinara sauce
• 3 cups water
• 2 cups shredded mozzarella cheese

Instructions

1. Brown the ground beef: Heat a skillet over medium heat. Add the ground beef and cook, breaking it into small crumbles, until completely browned. Drain any excess grease.
2. Combine the ingredients: Add the dry rigatoni directly to your slow cooker. Pour in the browned ground beef, marinara sauce, and water. Stir everything together until the pasta is evenly coated and mostly submerged in the liquid.
3. Slow cook the pasta: Cover and cook on LOW for 2 1/2 to 3 hours, stirring once or twice if necessary. Check the pasta toward the end of cooking to make sure it is tender and most of the liquid has been absorbed.
4. Add the mozzarella: Sprinkle the shredded mozzarella evenly over the cooked rigatoni. Cover and continue cooking for another 10 to 15 minutes, until the cheese melts into a delicious, gooey layer.
5. Serve and enjoy: Spoon the cheesy slow cooker rigatoni into serving bowls while hot. Enjoy with garlic bread or your favorite vegetable side dish.

Variations and Helpful Cooking Tips

1. Use Italian sausage instead of ground beef

For a richer and more robust flavor, replace the ground beef with mild Italian-style beef or turkey sausage. Brown it before adding it to the slow cooker.

2. Add extra Italian seasoning

If you enjoy a more flavorful tomato sauce, add garlic powder, dried oregano, Italian seasoning, or freshly ground black pepper. These simple additions complement the marinara sauce beautifully.

3. Check the pasta before the cooking time ends

Slow cookers can cook at different temperatures. Start checking the rigatoni around the 2 1/2-hour mark. Avoid overcooking, as pasta can become too soft if left in the slow cooker for too long.

4. Adjust the liquid if necessary

The pasta should remain mostly submerged during cooking. If the mixture looks too dry before the rigatoni is tender, add a little hot water. If excess liquid remains, allow it to cook uncovered briefly before adding the cheese.

5. Make it extra cheesy

Mozzarella creates a wonderfully stretchy topping, but you can also add grated Parmesan for a deeper, savory flavor. A combination of both cheeses makes this crockpot pasta even more delicious.

6. Add vegetables for extra flavor

Chopped bell peppers, sautéed mushrooms, fresh spinach, or zucchini are excellent additions. They bring extra color, flavor, and variety to this hearty pasta dinner.

7. Make a vegetarian version

Skip the ground beef and use a vegetable-based marinara sauce. Add mushrooms, spinach, or zucchini for a delicious meatless slow cooker rigatoni.

What to Serve with Slow Cooker Rigatoni

This cheesy ground beef rigatoni is filling enough to serve on its own, but a few simple sides can make dinner even better:

• Garlic bread or toasted Italian bread.
• Fresh garden salad with a light vinaigrette.
• Steamed green beans or broccoli.
• Roasted zucchini or carrots.
• Extra grated Parmesan cheese for serving.

Frequently Asked Questions

Can I put dry rigatoni directly into the slow cooker?

Yes! This recipe is designed to cook dry rigatoni directly in the slow cooker. The pasta absorbs moisture from the marinara sauce and water as it cooks. Make sure it is mostly submerged to help it cook evenly.

Do I need to cook the ground beef first?

Yes. Brown the ground beef in a skillet before adding it to the slow cooker. This improves its flavor and allows you to drain away excess grease.

How do I prevent rigatoni from becoming mushy?

Avoid cooking the pasta longer than necessary. Start checking for tenderness around 2 1/2 hours, since slow cooker temperatures can vary. Serve once the pasta is tender.

Can I prepare this recipe ahead of time?

You can brown the ground beef and refrigerate it in an airtight container ahead of time. For the best pasta texture, combine the ingredients shortly before cooking rather than leaving dry pasta soaking in the sauce overnight.

How do I store leftovers?

Allow the rigatoni to cool, then transfer it to an airtight container. Refrigerate for up to 3 to 4 days. Reheat individual portions in the microwave with a small splash of water to loosen the sauce.

Can I freeze leftover slow cooker rigatoni?

Yes. Store cooled portions in freezer-safe containers for up to 2 months for best quality. Thaw overnight in the refrigerator and reheat thoroughly. Keep in mind that the pasta may become softer after freezing.
