Method
- Place the frozen meatballs in the slow cooker.
- Add the sliced onions and mushrooms over the meatballs.
- In a bowl, whisk together the beef broth, onion soup mix, brown gravy mix, and Worcestershire sauce until well combined.
- Pour the sauce mixture evenly over the meatballs.
- Cover and cook on low for 5 to 6 hours or on high for 2 1/2 to 3 hours, until the meatballs are hot and the onions are tender.
- About 20 minutes before serving, mix the cornstarch and cold water in a small bowl to make a slurry.
- Stir the slurry and butter into the slow cooker, then cover and cook on high for 15 to 20 minutes, or until the gravy thickens.
- Taste and season with salt and black pepper if needed.
- Serve the Salisbury steak meatballs and gravy over mashed potatoes or egg noodles.
Notes
For extra flavor, brown the onions in a skillet before adding them to the slow cooker. If you prefer a thicker gravy, let the sauce cook uncovered for the last 10 minutes after adding the slurry.
