Ingredients
For the Hamburger Steaks
- 1.5 lbs (680g) lean ground beef
- 1 large (approx. 200g) yellow onion, thinly sliced
- 8 oz (225g) fresh mushrooms, sliced (optional)
- 1 tsp (5g) garlic powder
- 1 tsp (5g) onion powder
- ½ tsp (2.5g) salt, or to taste
- ¼ tsp (1.25g) black pepper, or to taste
For the Gravy
- 1 (10.5 oz / 298g) can cream of mushroom soup (condensed)
- 1 cup (240ml) beef broth
- 1 tbsp (15ml) Worcestershire sauce
- ½ tsp (2.5g) garlic powder
- ½ tsp (2.5g) onion powder
- Salt and black pepper to taste
Optional for Thickening Gravy
- 1-2 tbsp (8-16g) cornstarch mixed with 2-3 tbsp (30-45ml) cold water (cornstarch slurry)
Equipment: Heavy-duty aluminum foil
Ingredient Notes
- Ground Beef: Using lean ground beef (85/15 or 90/10) helps prevent the patties from becoming too greasy in the foil packets. If you use a higher fat content, you might want to drain some excess fat after cooking, though the foil often contains it well.
- Cream of Mushroom Soup: This forms the base of our classic, creamy gravy. You can substitute cream of chicken or cream of celery soup for a different flavor profile, but cream of mushroom offers that traditional Salisbury steak essence.
- Beef Broth: Use a good quality beef broth or stock for the best flavor. Low-sodium options allow you to control the salt content more easily.
- Worcestershire Sauce: This adds a crucial umami depth to the gravy, enhancing the beefy flavor. Donore is a great alternative if you don’t have it.
- Vegetables: Onions and mushrooms are traditional, but feel free to add other quick-cooking vegetables like bell peppers or thin potato slices if desired.
Equipment You’ll Need
- 6-quart or larger slow cooker
- Large mixing bowl
- Measuring cups and spoons
- Heavy-duty aluminum foil
How to Make Slow Cooker Foil Packet Hamburger Steaks
Making these easy slow cooker foil packet hamburger steaks is a breeze. Follow these steps for a delicious, comforting meal.

Step 1: Prepare the Hamburger Patties
- In a large bowl, gently combine the ground beef with 1 tsp garlic powder, 1 tsp onion powder, ½ tsp salt, and ¼ tsp black pepper. Be careful not to overmix, as this can make the patties tough.
- Divide the seasoned beef into 4-6 equal portions, depending on your desired serving size. Shape each portion into an oval or round patty, about ¾-inch (2 cm) thick. Make them slightly flatter and wider than you’d think, as they will shrink a bit during cooking.
Step 2: Assemble the Gravy
- In a separate medium bowl, whisk together the condensed cream of mushroom soup, beef broth, Worcestershire sauce, ½ tsp garlic powder, and ½ tsp onion powder until smooth.
- Season the gravy mixture with additional salt and pepper to taste.

Step 3: Create the Foil Packets
- Tear off 4-6 sheets of heavy-duty aluminum foil, each about 18 inches (45 cm) long. For extra security, you can use two layers of foil per packet.
- Place one prepared hamburger patty in the center of each foil sheet.
- Top each patty generously with sliced onions and optional sliced mushrooms.
- Pour an equal amount of the prepared gravy mixture over each patty and vegetables.
- Carefully bring the edges of the foil together over the ingredients and crimp tightly to seal the packets, creating a secure pouch. Ensure no gaps for steam or liquid to escape.

Step 4: Slow Cook the Hamburger Steaks
- Place the sealed foil packets directly into the bottom of your slow cooker. Stack them if necessary, but try to keep them in a single layer for even cooking if possible.
- Cover the slow cooker with its lid.
- Cook on LOW for 4-6 hours or on HIGH for 2-3 hours, or until the hamburger steaks are cooked through and tender. The internal temperature of the beef should reach 160°F (71°C).
Step 5: Serve and Enjoy
- Carefully remove the hot foil packets from the slow cooker using tongs.
- Open each packet with caution, as steam will escape.
- Serve the tender hamburger steaks with the rich gravy and vegetables. If you prefer a thicker gravy, transfer the gravy from the packets to a small saucepan, bring to a simmer, and whisk in the cornstarch slurry (1-2 tbsp cornstarch mixed with 2-3 tbsp cold water) until thickened to your liking.
Pro Tips for the Best Results
- Use Heavy-Duty Foil: This is crucial to prevent tearing and leakage. If you only have regular foil, use two layers per packet for added strength.
- Don’t Overmix the Beef: Overworking ground beef can lead to tough patties. Mix just until ingredients are combined.
- Seal Packets Tightly: A good seal ensures that all the moisture and flavor stay inside, resulting in incredibly tender and juicy steaks and a rich gravy.
- Consider Browning Patties (Optional): For an extra layer of flavor and a slightly firmer texture, quickly sear the patties in a hot skillet for 1-2 minutes per side before placing them in the foil packets. This step is entirely optional but adds depth.
- Adjust Gravy Consistency: If you like a very thick gravy, use the cornstarch slurry method mentioned in the instructions. You can also simply reduce the broth slightly if you prefer a thicker sauce without extra steps.
- Let Them Rest: Although they’re slow-cooked, letting the steaks rest in their gravy for a few minutes after opening the packets allows the juices to redistribute, ensuring maximum tenderness.
- Don’t Forget the Veggies: The onions and mushrooms not only add flavor but also become incredibly tender and sweet as they cook in the gravy.
Common Mistakes to Avoid
- Using Thin Foil: This can lead to tears and gravy leakage, making a mess and drying out your steaks.
- Not Sealing Packets Properly: If steam escapes, your steaks can dry out, and the gravy won’t be as rich. Ensure all edges are tightly crimped.
- Overcrowding the Slow Cooker: While stacking is sometimes necessary, try not to pack the slow cooker too tightly, as this can lead to uneven cooking.
- Under-Seasoning: Don’t be shy with the salt and pepper for the beef and gravy. Taste the gravy mixture before sealing packets and adjust as needed.
- Opening Packets Too Early: Resist the temptation to peek! The sealed environment is key to tender results.
Variations & Substitutions
- Add Potatoes: For a complete meal in one packet, add thinly sliced or diced potatoes (about 1/2-inch cubes) to the foil packets alongside the beef and onions. They will cook tenderly in the gravy.
- Cheesy Topping: In the last 15-30 minutes of cooking, you can carefully open the packets and sprinkle some shredded cheddar or provolone cheese over the hamburger steaks before resealing for a cheesy finish.
- Different Soups: While cream of mushroom is classic, cream of onion or cream of celery soup can be used for a slightly different flavor profile.
- Spice It Up: Add a pinch of red pepper flakes, smoked paprika, or a dash of hot sauce to the gravy for a bit of heat or smoky flavor.
- Fresh Herbs: Stir in some fresh chopped parsley, thyme, or rosemary into the gravy mixture for an aromatic boost.
- Bell Peppers: Add thinly sliced bell peppers (any color) for extra color and a mild, sweet flavor.

- Freezer: For longer storage, transfer the cooked steaks and gravy to freezer-safe containers or bags. They can be frozen for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating:
- Microwave: Reheat individual portions in the microwave until heated through, stirring the gravy occasionally.
- Stovetop: Gently reheat the steaks and gravy in a saucepan over medium-low heat, adding a splash of beef broth or water if the gravy is too thick.
- Oven: Place the steaks and gravy in an oven-safe dish, cover loosely with foil, and reheat at 300°F (150°C) until warmed through.
FAQ
Can I use ground turkey instead of ground beef?
Yes, you can use ground turkey, but be aware that it’s leaner and might result in slightly less tender patties. You may want to add a bit of olive oil or butter to the packets to prevent them from drying out, and adjust seasonings as needed.
Do I have to use foil packets? Can I just put everything directly in the slow cooker?
While you can technically cook everything directly in the slow cooker, the foil packets are key to this recipe’s appeal. They lock in moisture, create individual servings with their own gravy, and significantly reduce cleanup. Without them, the gravy might thin out more, and the patties could break apart more easily.
How do I make the gravy thicker?
After cooking, if you desire a thicker gravy, carefully pour the gravy from the packets into a small saucepan. Bring it to a gentle simmer over medium heat. In a separate small bowl, whisk together 1-2 tablespoons of cornstarch with 2-3 tablespoons of cold water until smooth (a slurry). Slowly whisk the slurry into the simmering gravy and cook for 1-2 minutes, stirring constantly, until thickened to your desired consistency.
Can I add vegetables other than onions and mushrooms?
Absolutely! Thinly sliced bell peppers, carrots, or even small chunks of potatoes work well. Just ensure they are cut into small pieces so they cook through at the same rate as the hamburger steaks.
How long do leftovers last in the refrigerator?
Properly stored in an airtight container, leftovers will stay fresh in the refrigerator for 3 to 4 days.
Can I prepare this recipe ahead of time?
You can assemble the foil packets up to 24 hours in advance and store them in the refrigerator. Then, simply place them in the slow cooker and cook as directed when ready.
