This easy slow cooker spaghetti sauce is a vegetable-packed meat sauce made from scratch. Perfect for busy weeknights and freezer-friendly batch cooking. Set it and forget it!
Brown the ground beef in a large skillet over medium heat until cooked through. Drain any excess fat and set aside.
Add the browned beef, crushed tomatoes, onion, celery, carrots, garlic, parsley, basil, oregano, nutmeg, red wine, salt, and pepper to the slow cooker.
Use a wooden spoon to break up the meat and stir until everything is mixed thoroughly.
Cover and cook on low for 6 to 7 hours or on high for 3 hours, stirring once or twice during cooking if you can. For a thicker sauce, remove the lid for the last 30 minutes.
Taste and adjust salt and pepper. Serve hot over your favourite cooked pasta and top with fresh grated Parmesan and a sprinkle of parsley.
