How to Make Slow Cooker One Pot Spaghetti

Step 1: Brown the Ground Beef

In a large skillet over medium-high heat, cook the ground beef until browned and no longer pink, breaking it apart with a spoon as it cooks. Drain any excess grease.

Step 2: Add Ingredients to the Slow Cooker

Transfer the cooked beef to the slow cooker. Add the marinara sauce, beef broth, and Italian seasoning. Stir until fully combined.

Step 3: Slow Cook the Sauce

Cover and cook on LOW for 3 to 4 hours or HIGH for 1 1/2 to 2 hours so the flavors can develop.

Step 4: Add the Spaghetti

About 45 to 60 minutes before serving, stir the sauce mixture and add the dry spaghetti. Press the noodles down into the liquid so they are mostly submerged.

Step 5: Finish Cooking

Cover and cook on HIGH for 30 to 45 minutes, stirring once or twice, until the pasta is tender and coated in sauce.

Step 6: Adjust and Serve

Stir everything together well before serving. If the sauce is too thick, add a splash of broth or water. Serve hot with grated Parmesan cheese or red pepper flakes if desired.

Pro Tips for the Best Slow Cooker Spaghetti

• Browning the beef first adds better flavor and texture.
• Break the spaghetti in half so it cooks evenly in the slow cooker.
• Stir the pasta once or twice while cooking to prevent sticking.
• Add extra broth if your slow cooker runs hot.
• Check the pasta early the first time you make it to avoid overcooking.

Easy Variations

• Stir in shredded mozzarella cheese for a cheesy version.
• Add chopped vegetables like carrots, spinach, or bell peppers.
• Use ground turkey or chicken instead of beef.
• Swap half the beef for Italian sausage for richer flavor.
• Add crushed red pepper flakes for a spicy kick.

Serving Suggestions

Serve this cozy spaghetti dinner with garlic bread, crusty bread, or a fresh green salad tossed with Italian dressing. Roasted broccoli, green beans, or zucchini also make easy side dishes that balance the richness of the sauce.

Set out bowls of grated Parmesan cheese, mozzarella, or fresh herbs so everyone can customize their own plate.

Storage and Reheating Tips

Store leftovers in an airtight container in the refrigerator for up to 4 days. The pasta will absorb more sauce as it sits, so add a splash of broth or water before reheating.

Reheat gently on the stovetop or in the microwave until warmed through.
