Ingredients You’ll Need
· 2 lbs ground beef (80/20 or 85/15 works best)
· ½ cup breadcrumbs
· 1 large egg
· 1 packet (1 oz) dry onion soup mix, divided
· ¼ cup whole milk
· 1 teaspoon garlic powder
· ½ teaspoon black pepper
· 8 oz sliced mushrooms (white or cremini)
· 1 can (10.5 oz) cream of mushroom soup
· 1 cup beef broth
· 1 tablespoon Worcestershire sauce
· 2 tablespoons cornstarch + 3 tablespoons cold water (for slurry)
· Fresh parsley, chopped, for garnish
· Optional: 1 small onion, sliced; 4 slices Swiss cheese
Step-by-Step Instructions
- Make the Patties: In a large bowl, combine the ground beef, breadcrumbs, egg, half of the onion soup mix, milk, garlic powder, and black pepper. Mix gently until just combined—do not overmix.
- Shape: Shape the mixture into 4–6 equal oval patties, about ½-inch thick. Press a slight indentation in the center of each.
- Layer the Slow Cooker: Place the patties in the bottom of the slow cooker. Scatter the sliced mushrooms (and sliced onion, if using) over the top. Sprinkle the remaining onion soup mix over the mushrooms.
- Make the Gravy: In a medium bowl, whisk together the cream of mushroom soup, beef broth, and Worcestershire sauce. Pour evenly over the patties and mushrooms.
- Cook Low and Slow: Cover and cook on LOW for 5–6 hours or on HIGH for 3–4 hours, until the patties are cooked through (internal temperature of 160°F) and tender.
- Thicken the Gravy: Remove the patties and set aside. In a small bowl, whisk the cornstarch with cold water to make a slurry. Stir the slurry into the slow cooker juices. Turn to HIGH and cook for 15–20 minutes, until the gravy thickens.
- Optional Cheese: If using Swiss cheese, place a slice on each patty and return to the slow cooker for the last 5 minutes, until melted.
- Serve: Return the patties to the gravy, spoon some over the top, garnish with fresh parsley, and serve hot over mashed potatoes, egg noodles, or rice.
Tips for the Best Slow Cooker Hamburger Steaks
· Don’t Overmix: Mix the meat mixture just until combined. Overmixing makes the patties tough.
· Use 80/20 Ground Beef: A little fat keeps the patties juicy and flavorful.
· Sear First (Optional): For extra depth, sear the patties in a hot skillet for 2–3 minutes per side before adding to the slow cooker.
· Thicken at the End: The gravy will be thin after cooking. The cornstarch slurry is essential for a rich, glossy sauce.
· Check Temperature: Ground beef should reach 160°F. Slow cookers vary, so check at the minimum time.
· Make It a Meal: Serve with mashed potatoes and green beans for a complete comfort food dinner.
Variations & Substitutions
· Turkey or Chicken: Substitute ground turkey or chicken for a lighter option.
· Mushroom Swiss: Top each patty with Swiss cheese and extra mushrooms.
· Onion Gravy: Add sliced onions and use onion soup mix for a classic flavor.
· Spicy: Add red pepper flakes or diced jalapeños to the meat mixture.
· Gluten-Free: Use gluten-free breadcrumbs, gluten-free onion soup mix, gluten-free cream of mushroom soup, and gluten-free beef broth.
· Low-Carb: Serve over cauliflower rice or zucchini noodles.
