Ingredients
Method
- Melt the butter in a large skillet over medium heat. Whisk in the flour and cook for 2 minutes, stirring constantly. Slowly whisk in the beef broth, then add the soup, Worcestershire, Dijon, garlic powder, onion powder, and black pepper. Whisk until smooth and slightly thickened, about 1 minute.
- Place the frozen meatballs in a 4- to 6-quart slow cooker. Pour the sauce over them and stir gently. Cover and cook on LOW for 6 to 8 hours or on HIGH for 3 to 4 hours, until the meatballs are hot through and the sauce is bubbling.
- Remove ½ cup of hot liquid from the slow cooker and whisk with the sour cream in a small bowl. Pour the mixture back into the cooker and stir until creamy. Cook uncovered on LOW for 5 minutes to warm through.
- Spoon the meatballs and gravy over egg noodles or mashed potatoes, garnish with parsley, and serve hot.
Notes
If you like a thicker gravy, whisk 1 tablespoon cornstarch with 2 tablespoons cold water and stir it into the slow cooker during the last 10 minutes, leaving the lid off. The sauce will also continue to thicken as it sits for a moment after serving.
