These slow cooker Salisbury steak meatballs are rich, savory, and ultra delicious. Frozen meatballs are cooked until soft and tender, teamed up with a hearty mushroom gravy, and served with some rice or mashed potatoes. If you’ve been craving something wholesome and delicious, but affordable and low-effort, this easy recipe ticks all those boxes.
Place the sliced mushrooms and onions in the bottom of a 6-quart crock pot. Then pour frozen meatballs over the top.
Add beef broth, gravy mix, Worcestershire sauce, ketchup, mustard, black pepper, and garlic in a medium bowl. Whisk until well combined and pour over meatballs.
Cover and cook on high for 2-3 hours or low for 5-6 hours.
In a small bowl, whisk cornstarch and water together. Pour over the meatballs and mix until well combined. Cook for ten minutes or until the gravy thickens.
Serve over rice or mashed potatoes, and enjoy!
Notes
Want to have a chunkier mushroom gravy? Slice the mushrooms thicker.
Swap the frozen meatballs with plant-based meatballs or a combination of lentils and mushrooms to try a vegetarian or vegan version of the dish. Remember that each of these will take considerably less time to cook.
To enhance the flavor and depth of the gravy, add a splash of red wine or add some beef bouillon granules into the mix.
Don’t have the brown gravy mix the recipe calls for? Use some beef bouillon or beef broth along with some cornstarch and spices like onion and garlic powder and some paprika to make your own homemade version.
