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.
2 cans (15 ounces each) tomato sauce – For a rich, tangy sauce.
8 ounces dry tubular pasta (such as rigatoni, ziti, or penne) – For a hearty, satisfying base.

Step-by-Step Instructions

Step 1: Brown the Beef and Onion

In a skillet over medium heat, cook the ground beef and chopped onion together 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: Transfer to the Slow Cooker

Transfer the beef and onion mixture to the slow cooker and stir in the tomato sauce.

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 4 to 5 hours so the flavors can meld and the sauce can deepen.

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

Step 4: Cook the Pasta

About 20 minutes before serving, cook the pasta in salted boiling water until just tender. Drain well.

Pro Tip: Cook the pasta just until al dente—it will continue to soften when stirred into the hot sauce.

Step 5: Combine and Serve

Stir the drained pasta into the sauce, cover, and let it sit on warm for 10 to 15 minutes so the pasta can absorb some of the flavor. Spoon into bowls and serve hot.

Pro Tip: Serve with crusty bread and a sprinkle of Parmesan for a complete meal.
