  • In a large mixing bowl, add ground beef, Panko bread crumb, egg, ketchup, mustard powder, Worcestershire sauce, steak seasoning, black pepper, onion powder and salt.
  • Knead until completely combined and form into medium sized meatballs. For this recipe, I just use ½ cup spoon and mold the meat into meatballs.
  • Heat a large skillet or dutch over medium heat. Add the meatballs and gently move around the pan to brown. Transfer the meatballs to the slow cooker.
  • Using the same skillet, add butter and cook onions for about 3-4 minutes until softened. Transfer them to the slow cooker.
  • Add mushrooms, ketchup, broth and Worcestershire sauce into the slow cooker and cook for about 2-3 hours on high or 4-5 hours on low.
  • In a small bowl, beat cornstarch and cold water. Quickly stir and pour the mixture into slow cooker and increase the heat to high until the sauce is thicken. Cook for about 5-10 minutes. Serve with Idaho Spuds VeggieMash and chopped parsley.
