This easy Crockpot Salisbury Steak is a true winner! Juicy, flavorful ground beef patties cook slowly with mushrooms and onions in a savory gravy. In just a few simple steps and the convenience of your slow cooker, you'll have a hearty and satisfying dinner with little effort on your part.
Place the sliced mushrooms and onions in the bottom of a 6-quart slow cooker.
In a large bowl, add all ingredients for the steaks. Mix until combined, and try not to over-mix. Form into six patties and brown over medium-high heat in a skillet for 2-3 minutes on each side.
Place steaks on top of mushrooms and onions.
Add beef broth, gravy mix, ketchup, mustard, black pepper, and garlic in a medium bowl. Whisk until well combined and pour over steaks.
Cover and cook on high for 2-3 hours or low for 5-6 hours.
In a small bowl, whisk cornstarch and water together. Remove steaks and set aside. Pour cornstarch slurry into the gravy and whisk until well combined. Add steaks back into the sauce and cook for ten minutes or until the gravy thickens.
Sever over mashed potatoes or rice and enjoy!
Notes
In case the gravy becomes too thin, you have the option to thicken it by making an extra slurry using cornstarch. Begin by carefully pouring the slurry into the slow cooker while stirring thoroughly. Allow it to cook for an additional 10 minutes, or until the gravy reaches the desired thickness. If necessary, you can repeat this procedure, gradually adding small amounts of slurry at a time until you achieve the desired consistency.
Although the recipe specifies brown mushrooms, you can opt for alternative mushroom varieties like cremini, white button mushrooms, or even portobello mushrooms to enhance the robustness of the flavor.
