The Ingredients

This recipe uses simple, affordable ingredients that come together beautifully.

1 pound ground beef – 80/20 for the best flavor.
1 medium onion, finely chopped – For savory depth.
1 jar (24 ounces) pasta sauce – For tang and richness.
8 ounces egg noodles, uncooked – For tender, satisfying pasta.
1 cup shredded mozzarella cheese – For a gooey, melted topping.

Step-by-Step Instructions

Step 1: Brown the Beef and Onion

In a skillet over medium heat, cook the ground beef and chopped onion until the beef is browned and the onion is soft. Drain off any excess grease.

Pro Tip: Break the beef into small, even crumbles for even distribution.

Step 2: Add to the Slow Cooker

Spoon the beef and onion mixture into the slow cooker, then stir in the pasta sauce until everything is evenly coated.

Pro Tip: Stir well to ensure the beef is evenly coated in the sauce.

Step 3: Cook Low and Slow

Cover and cook on low for 3 hours so the flavors can blend together.

Pro Tip: Don’t lift the lid! Every time you open the slow cooker, you lose heat and add cooking time.

Step 4: Add the Noodles

Stir in the uncooked egg noodles, cover again, and cook on high for 20 to 30 minutes, or until the noodles are tender. If the mixture seems too thick, add a small splash of water.

Pro Tip: Stir once or twice to prevent the noodles from sticking together.

Step 5: Add the Cheese

Sprinkle the mozzarella cheese over the top, cover, and let it sit for 5 to 10 minutes until the cheese melts. Give it a gentle stir if you like a creamier finish, then serve hot.

Pro Tip: Serve with crusty bread and a simple green salad for a complete meal.

Add noodles at the end. They cook quickly and absorb the sauce.
Stir once or twice. Prevents the noodles from sticking.
