Meat-Lover's Slow Cooker Spaghetti Sauce

Step 1

Heat olive oil in a skillet over medium heat; cook and stir onions and Italian sausage until the sausage is browned, about 10 minutes. Transfer the sausage and onions to a slow cooker. In the same skillet, cook and stir the ground beef, Italian seasoning, 1 teaspoon of garlic powder, and marjoram, breaking the meat up as it cooks, until the meat is browned, about 10 minutes. Transfer the ground beef into the slow cooker.

Step 2

Stir in the tomato sauce, tomato paste, diced tomatoes, stewed tomatoes, thyme, basil, oregano, and 2 teaspoons of garlic powder. Set the cooker on Low, and cook the sauce for 8 hours. About 15 minutes before serving, stir in the sugar. Serve hot.
