Ingredients

• Spaghetti: Regular dried spaghetti works best in this recipe. Breaking it in half makes it easier to stir and serve from the slow cooker.
• Cheddar Cheese: Use freshly shredded cheese for the best melting qualities. Pre-shredded cheese contains anti-caking agents that can affect the creamy texture.
• Pasta Sauce: Choose your favorite jarred pasta sauce as the foundation for flavor. Marinara, tomato and basil, or even roasted garlic varieties all work wonderfully.
• Ground Meat: Ground beef provides classic flavor, but ground turkey is a leaner alternative. Make sure to drain excess fat before adding to the slow cooker.

Variations

Vegetarian Version

Skip the meat completely and add 2 cups of chopped vegetables like bell peppers, zucchini, and mushrooms instead. You can also add a can of drained and rinsed beans for protein.

Spicy Cheesy Spaghetti

Add red pepper flakes or diced jalapeños to the sauce mixture before cooking. Using pepper jack cheese instead of or along with the cheddar will also give it a nice kick.

Italian Upgrade

Enhance the Italian flavors by using Italian sausage instead of ground beef, adding a tablespoon of Italian seasoning, and topping with a mixture of mozzarella and parmesan cheese instead of cheddar.

How to Make the Recipe

Step 1: Brown the Meat

In a skillet over medium heat, cook the ground beef or turkey until it’s no longer pink, breaking it up with a wooden spoon as it cooks. Drain any excess fat completely to prevent greasiness in the final dish.

Step 2: Combine Ingredients

Add the cooked meat to your slow cooker along with the pasta sauce and half of the shredded cheddar cheese. Stir everything together until well combined, creating a rich base for your pasta.

Step 3: Add Spaghetti

Break the spaghetti in half and add it to the slow cooker, stirring carefully to coat all the pasta with sauce. Make sure all the pasta is submerged in the sauce mixture to ensure even cooking.

Step 4: Slow Cook

Cover the slow cooker and cook on low heat for 2-3 hours. Check and stir occasionally (about every 30-45 minutes) to prevent sticking and to make sure the pasta cooks evenly.

Step 5: Add Cheese Topping

When the pasta is tender, sprinkle the remaining cheddar cheese over the top. Cover and cook for an additional 15 minutes until the cheese is fully melted and gooey.

Tips for Making the Recipe

• Don’t overcook the pasta – start checking for doneness around the 2-hour mark as slow cookers can vary in temperature
• Stir occasionally during cooking to prevent the pasta from sticking together or to the sides of the slow cooker
• Spray your slow cooker with non-stick cooking spray before adding ingredients for easier cleanup
• For best texture, serve immediately after the final cheese has melted
• If the mixture seems dry during cooking, add a splash of water or chicken broth
• For extra flavor, sauté the meat with diced onions and minced garlic before adding to the slow cooker

How to Serve

Serve this cheesy spaghetti hot from the slow cooker with a sprinkle of fresh herbs like basil or parsley on top. Pair with a simple green salad and garlic bread for a complete meal. For a restaurant-style presentation, serve the spaghetti with extra grated parmesan cheese, red pepper flakes, and a drizzle of olive oil available for guests to customize their portions.

Make Ahead

This recipe is perfect for meal prep and can be approached in several ways. You can brown the meat up to 2 days ahead and store it in the refrigerator until needed. The entire dish can be fully cooked and refrigerated for up to 3 days – simply reheat portions in the microwave with a splash of water to revive the sauce. For freezing, cool the cooked spaghetti completely, portion into freezer-safe containers, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

FAQs

Can I use other types of pasta instead of spaghetti?

Yes, you can substitute other pasta shapes like penne, rotini, or fusilli. Shorter pasta shapes don’t need to be broken and may cook more evenly in the slow cooker.

Why is my pasta mushy?

Pasta can become mushy if cooked too long in the slow cooker. Make sure to check it at the 2-hour mark and turn off the heat once it reaches al dente texture.

Can I add vegetables to this recipe?

Absolutely! Add vegetables like diced bell peppers, mushrooms, or spinach. Heartier vegetables can go in at the beginning, while quick-cooking ones like spinach should be added in the last 30 minutes.

Can I make this in an Instant Pot instead?

Yes, this recipe can be adapted for an Instant Pot. Brown the meat using the sauté function, add remaining ingredients except the final cup of cheese, and cook on high pressure for about 5 minutes with a quick release. Stir well, add the remaining cheese, and let it melt with the lid on.
