Make the Gravy Whisk the beef broth, Worcestershire sauce, ketchup and water in a bowl. Add the gravy mix packet and onion soup mix packet, mixing until well combined. That makes for a deep and flavorful sauce without a ton of seasoning.
Combine in the Slow Cooker – Add the frozen meatballs to the slow cooker, and pour over the mixing bowl of prepared gravy. Gently stir to coat all the meatballs.
Slow Cook – Cover and cook on low for 4-5 hours or high for 2-3 hours, during which time the meatballs will soak up the savory flavors. Stir and break well to mix and cook evenly.
Thicken and Serve — 30 minutes before serving: In a very small bowl, combine cornstarch with a bright splash of water to form a slurry, then stir into slow cooker’s gravy, to thicken consistency. When the sauce is at a desired consistency.
NOTES
For Over-Thickening – if the gravy is too thick, add a bit more beef broth or water to achieve your desired consistency. Adding liquid gradually preserves the hearty flavor and keeps it from getting sloppy.
Deepen the Flavor — For a more bruise-in-your-face, homemade flavor, stir in a splash of Worcestershire sauce or a teaspoon of Dijon mustard to the gravy. “Just a pinch of paprika or smoked paprika can also add a nice gentle warmth and depth of flavor to the dish.”
