Ingredients
2 lbs ground beef (900 g)
1/2 cup breadcrumbs
1 egg
1 small onion, finely chopped
2 cups sliced mushrooms
2 cups beef broth
1 packet brown gravy mix
1 tablespoon Worcestershire sauce
1 teaspoon garlic powder
Salt and black pepper to taste
1 tablespoon ketchup (optional)
1 tablespoon cornstarch mixed with 2 tablespoons cold water (optional, for thickening)
Instructions
Make the patties: Combine ground beef, breadcrumbs, egg, chopped onion, garlic powder, salt, and pepper. Shape into 6 oval patties.
Prepare the gravy: Mix beef broth, brown gravy mix, Worcestershire sauce, and ketchup in a bowl.
Layer the ingredients: Place the patties in the slow cooker. Add the sliced mushrooms and pour the gravy mixture over them.
Slow cook: Cover and cook on LOW for 5–6 hours or HIGH for 3–4 hours, until the beef reaches a safe internal temperature of 160°F (71°C).
Thicken the gravy: If needed, stir in the cornstarch slurry during the final 15–20 minutes.
Serve: Spoon the rich mushroom gravy over the patties and serve with mashed potatoes, rice, or steamed vegetables.
