Ingredients
For the Burger Patties
- 1 lb ground beef (or turkey/chicken for a lighter option)
- 1 tablespoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
For the Toppings
- 1 cup sliced mushrooms

For Assembly
- 1 tablespoon olive oil (for greasing the foil)
- Fresh parsley, chopped (optional for garnish)
- Heavy-duty aluminum foil (enough for 4 packets)
How to Make Mushroom and Swiss Burger Foil Packets
Step 1: Prepare the Burger Patties
In a large bowl, combine the ground beef with Worcestershire sauce, garlic powder, salt, and black pepper. Mix gently but thoroughly. Divide this mixture into four equal portions and shape each portion into a patty.
Step 2: Prepare the Foil
Tear off four large pieces of aluminum foil, each about 12 inches long. Lightly coat the center of each piece with olive oil to prevent sticking during cooking.
Step 3: Assemble the Packets
Place one burger patty in the center of each piece of foil. Top each patty with a generous handful of sliced mushrooms. Add one slice of Swiss cheese on top of each burger.
Step 4: Seal the Packets
Fold the sides of the foil over each burger along with its toppings. Roll up the edges tightly to create sealed packets that trap in moisture and flavor.
Step 5: Grill or Bake the Packets
Preheat your grill to medium-high heat or set your oven to 400°F (200°C). If grilling, place the packets directly on the grill grates and cook for about 15-20 minutes, flipping halfway through. If baking, arrange them on a baking sheet and bake in your preheated oven for 20-25 minutes.
Step 6: Check Doneness
After cooking for 15-20 minutes on the grill or 20-25 minutes in the oven, carefully open one packet to ensure that the burger is fully cooked. Close it back up if more time is needed.
Step 7: Serve
Once cooked through, remove the packets from your grill or oven. Allow them to cool slightly before unwrapping carefully. Garnish with fresh parsley if desired and serve immediately for an unforgettable meal!
