🛒 Ingredients
For the Hamburger Steaks
- 2 lbs ground beef (80/20 works best)
- 1 large egg
- ½ cup breadcrumbs (or crushed crackers)
- 1 tablespoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon smoked paprika (optional)
For the Gravy & Base
- 1 large onion, thinly sliced
- 8 oz mushrooms, sliced (button or cremini)
- 2 cups beef broth
- 1 can (10.5 oz) cream of mushroom soup
- 2 tablespoons Worcestershire sauce
- 1 teaspoon garlic powder
- ½ teaspoon black pepper
- 2 tablespoons cornstarch + 2 tablespoons cold water (for thickening, optional)
- Fresh parsley, chopped (for garnish)
Optional for Serving
- Mashed potatoes
- Egg noodles
- White rice
- Extra gravy on the side
👩🍳 Instructions
- Make the Patties
In a large bowl, combine ground beef, egg, breadcrumbs, Worcestershire sauce, garlic powder, onion powder, salt, black pepper, and smoked paprika. Mix gently with your hands until just combined — don’t overmix or the patties will be tough. Form into 6–8 oval or round patties about ¾-inch thick. - Layer the Slow Cooker
Place the sliced onions in an even layer on the bottom of a 6-quart slow cooker. Arrange the raw hamburger patties on top of the onions in a single layer (it’s okay if they overlap slightly). - Make the Gravy
In a medium bowl, whisk together the beef broth, cream of mushroom soup, Worcestershire sauce, garlic powder, and black pepper until smooth. Stir in the sliced mushrooms. Pour the gravy mixture evenly over the patties, making sure everything is coated. - Cook
Cover and cook on Low for 5–6 hours or on High for 3–3½ hours, until the patties are cooked through and tender. - Thicken the Gravy (Optional)
If you prefer a thicker gravy, mix the cornstarch with cold water to make a slurry. Remove the patties to a plate, stir the slurry into the slow cooker, and cook on High for 10–15 minutes until thickened. Return the patties to the gravy. - Serve
Spoon the hamburger steaks and generous amounts of mushroom gravy over mashed potatoes, egg noodles, or rice. Garnish with chopped fresh parsley.
🔥 Tips for the Best Results
- Don’t overwork the meat mixture — gentle mixing keeps the patties tender.
- 80/20 ground beef gives the best flavor and juiciness. Leaner beef can turn out drier.
- For extra flavor, you can quickly sear the patties in a hot skillet before adding them to the slow cooker (optional but delicious).
- Cream of mushroom soup creates a creamy gravy with almost no effort. You can use cream of onion or golden mushroom soup as a variation.
- The onions on the bottom create a flavorful base and prevent the patties from sticking.
- Leftovers reheat beautifully and taste even better the next day.
🍗 Easy Flavor Variations
🧅 French Onion Style
Swap the cream of mushroom soup for cream of onion soup and add a splash of white wine or extra Worcestershire.
🌶️ Spicy Kick
Add ½ teaspoon cayenne or a few dashes of hot sauce to the gravy, and mix a little chili powder into the patties.
🧄 Garlic Butter Version
Stir 2–3 tablespoons of butter and extra minced garlic into the gravy during the last 30 minutes of cooking.
🍄 Extra Mushroom
Double the mushrooms and use a mix of cremini and shiitake for deeper flavor.
🍽️ Serving Ideas

💡 Frequently Asked Questions
Can I use frozen patties?
Yes, but add an extra 30–60 minutes to the cook time and make sure they reach a safe internal temperature.
Can I make this without cream of mushroom soup?
Yes. Use 2 extra cups of beef broth + ½ cup heavy cream or half-and-half, and thicken with the cornstarch slurry at the end.
Do I need to brown the patties first?
No, it’s not required. The slow cooker method works great with raw patties. Searing is optional for extra flavor and color.
Can I cook this on High the whole time?
Yes — 3 to 3½ hours on High works well if you’re short on time.
🥡 Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
Reheat gently on the stove or in the microwave with a splash of broth to loosen the gravy. You can also freeze cooked patties with gravy for up to 2 months.
