Delicious Salisbury Steak Meatballs Recipe You Have to Try

First, mix together the ground beef, breadcrumbs, egg, mustard, ketchup, Worcestershire sauce, salt, and pepper in a large bowl. Once everything is well combined, roll the mixture into meatballs.

In a large skillet, heat the olive oil over medium-high heat. Add the meatballs and cook until they are browned on all sides, about 8-10 minutes. Once browned, remove the meatballs from the skillet and set them aside.

Now it’s time to make the rich and savory onion gravy.

In the same skillet, add sliced onions and cook until they are soft and golden brown, about 5-7 minutes. Sprinkle flour over the onions and cook for 1-2 minutes, stirring constantly.
