  • 1 tsp onion powder

How to Make Mushroom and Swiss Burger Foil Packets

Step 1: Preheat and Prepare

Preheat your grill to medium-high heat (400°F / 200°C) or your oven to 375°F (190°C).
Tear off 4 large sheets of heavy-duty aluminum foil and lightly spray with nonstick cooking spray.

Step 2: Shape the Patties

In a bowl, mix ground beef, salt, pepper, garlic powder, and onion powder.
Form into 4 equal patties, about ½ inch thick.

Step 3: Cook the Mushrooms

In a small pan, melt butter and sauté mushrooms (and onions if using) for about 5 minutes, until golden. Stir in Worcestershire sauce and cook for 1 more minute.

Step 4: Assemble the Packets

Place one burger patty in the center of each foil sheet. Top with sautéed mushrooms and a slice of Swiss cheese.
Fold the foil over to create a sealed packet.

Step 5: Cook

  • On the grill: Cook for 12–15 minutes, flipping halfway through.
  • In the oven: Bake for 20–25 minutes on a baking sheet.

Step 6: Serve and Enjoy

Carefully open the foil (watch for steam!) and garnish with parsley.
Serve as is, or on a toasted bun with your favorite condiments.


Tips for Perfect Foil Packet Burgers

  • Use heavy-duty foil to avoid tearing.
  • Add veggies: Bell peppers or sliced zucchini pair beautifully.
  • Make it creamy: Add a spoonful of sour cream or a drizzle of mushroom sauce before sealing.
  • Go low-carb: Skip the bun and enjoy straight from the foil!
