Servings: 6
Prep Time: 10 minutes
Cook Time: 2–3 hours

Ingredients

• 1 pound thick, sturdy pasta such as rigatoni
• 1 jar (24 ounces) savory tomato pasta sauce
• 1 can (14.5 ounces) diced tomatoes, undrained
• 2 cups shredded mozzarella cheese
• 1 cup water

How to Make Slow Cooker Pasta

1. Lightly coat the inside of your slow cooker with cooking spray for easier cleanup.
2. Add the tomato pasta sauce, undrained diced tomatoes, and water. Stir until well combined.
3. Add the dry rigatoni and mix thoroughly, making sure the pasta is coated with the sauce and mostly submerged.
4. Cover and cook on LOW for 2 to 3 hours, stirring once or twice if your slow cooker tends to run hot. Cook until the pasta is tender and most of the liquid has been absorbed.
5. Sprinkle the shredded mozzarella evenly over the pasta. Cover and cook for another 10 to 15 minutes, or until the cheese is completely melted.
6. Gently stir and serve hot.

Tips for the Best Crockpot Pasta

Choose sturdy pasta. Rigatoni and other thick pasta shapes hold their texture better during slow cooking. Avoid very thin pasta, which can become overly soft.

Check early. Slow cooker temperatures vary, so begin checking the pasta around the 2-hour mark. Overcooking can make the pasta mushy.

Add a little water if needed. If the sauce becomes too thick before the pasta is fully tender, stir in a small splash of water.

Boost the flavor. Dried oregano, basil, garlic powder, black pepper, or red pepper flakes can add extra flavor without complicating the recipe.

Make it extra cheesy. For a richer finish, use a combination of mozzarella and Parmesan cheese.

Easy Variations

Slow Cooker Beef Pasta: Add cooked and drained ground beef for a hearty beef-and-pasta dinner.

Chicken Pasta: Stir in cooked shredded rotisserie chicken for an easy chicken pasta variation.

Italian Sausage Pasta: Add cooked crumbled Italian sausage for a richer, more savory flavor.

Vegetable Pasta: Add chopped bell peppers, mushrooms, spinach, or zucchini for an easy way to include more vegetables.

What to Serve With Crockpot Pasta

Turn this easy slow cooker pasta into a complete family dinner by serving it with a crisp green salad, roasted vegetables, or warm garlic bread. A little grated Parmesan and fresh parsley on top also gives each serving a restaurant-style finish.

Frequently Asked Questions

Can you cook dry pasta in a slow cooker?
Yes. Sturdy pasta such as rigatoni can be cooked directly in the slow cooker when there is enough liquid. Keep an eye on the cooking time because pasta can become soft quickly.

Can I use another type of pasta?
Yes, but choose a sturdy shape such as penne, ziti, or rigatoni. Cooking times may vary depending on the pasta shape.

Can I add meat?
Absolutely. Cooked ground beef, Italian sausage, or shredded chicken are excellent additions. Make sure meat is fully cooked before adding it.

Can I make this pasta ahead of time?
It is best served soon after cooking because the pasta continues absorbing sauce as it sits. If reheating leftovers, add a small splash of water or extra sauce to loosen them.
