Make the Slow Cooker Salisbury Steak Meatballs (frozen Meatballs) Recipe for an easy, savory weeknight dinner with rich gravy and tender meatballs.
Give your slow cooker a quick spray of nonstick cooking spray so the meatballs and gravy release easily once done; this little step saves cleanup and helps the caramelized bits slide free when you serve. Keep the insert on the White Quartz while you work so everything stays tidy and ready for the next move, then close the lid until you add the meatballs.
Pour the entire bag of frozen meatballs into the slow cooker insert straight from the freezer — no thawing needed. Arrange them so they sit in an even layer; they’ll warm and cook evenly during the long, gentle braise and won’t clump together if given a little space.
In a mixing bowl whisk together the beef broth, brown gravy mix, onion soup mix, ketchup, and Worcestershire sauce until perfectly smooth and glossy. Pour this savory mixture evenly over the frozen meatballs and stir gently so each sphere gets a light coat of seasoning before the slow cook begins. This is the moment when the raw, individual components become a single braising liquid that will flavor the meatballs from the inside out.

Cover the slow cooker and set it to LOW, then let the dish cook for 5 to 6 hours. During this quiet interval the meatballs gently knit with the gravy, transforming from firm frozen spheres into tender, flavor-soaked bites; the liquid reduces slightly and deepens in color as the umami components marry.
When the cook time is up, whisk the cornstarch and cold water until smooth to make a slurry, then stir it into the crockpot. Let the pot continue on LOW for about 10 minutes until the gravy thickens and becomes glossy, clinging to the meatballs in a viscous, saucy blanket that will cling to noodles or mash.

Spoon the Salisbury steak meatballs and plenty of warm, glossy gravy over a bed of pillowy mashed potatoes or buttered egg noodles. Finish with a scattering of finely chopped parsley for a fresh green pop and serve while steaming hot — this cozy, home-style plate is made for digging into on a chilly evening.
