This slow cooker spaghetti sauce simmers to perfection for rich tomato flavor infused with ground beef and warm Italian spices — a true comfort food classic that's simple to prepare.
Heat a large skillet over medium heat and brown the ground chuck. Drain excess fat.
Add diced onion and minced garlic to the skillet and cook until soft, about 5 minutes.
Transfer the beef, onion, and garlic mixture to the slow cooker.
Stir in crushed tomatoes, tomato paste, tomato sauce, and sugar until combined.
Add basil, Italian seasoning, salt, pepper, and Worcestershire sauce. Stir well.
Cover and cook on low for 8 hours. Stir and serve over cooked pasta.
Notes
For quicker results, cook on high for 3 to 4 hours, but low and slow is best for flavor. Store leftovers in airtight containers and refrigerate or freeze for later use.
