🍔 Mushroom & Swiss Burger Foil Packets
🛒 Ingredients (Serves 2–4)
For the burgers:
- 1 lb (450 g) ground beef (80/20 for juiciness)
- ½ tsp garlic powder
- ½ tsp onion powder
- ½ tsp salt
- ¼ tsp black pepper
For the mushrooms & veggies:
- 1 cup mushrooms, sliced (button or cremini)
- 1 small onion, thinly sliced
- 1 tbsp butter or olive oil
- Salt and pepper to taste
Other ingredients:
- 4 slices Swiss cheese
- 2–4 burger buns (optional, serve on the side or toast in foil)
- Fresh parsley or thyme for garnish (optional)
Foil & assembly:
- 4 large pieces of aluminum foil (one per burger or 2 per packet for sharing)
👩🍳 Instructions
1. Prepare the burgers
- In a bowl, combine ground beef with garlic powder, onion powder, salt, and pepper.
- Form into 4 evenly sized patties.
2. Cook the mushrooms & onions
- In a skillet, melt butter over medium heat.
- Sauté mushrooms and onions until soft and golden (~5–7 minutes). Season lightly with salt and pepper.
- Remove from heat.
3. Assemble the foil packets
- Place each burger patty in the center of a large piece of foil.
- Top with sautéed mushrooms and onions.
- Place a slice of Swiss cheese on top of each burger.
- Fold the foil around the burger to make a sealed packet.
4. Cook
- Grill method: Preheat grill to medium-high. Place packets on the grill for 12–15 minutes, flipping halfway through.
- Oven method: Preheat oven to 400°F (200°C). Bake packets on a baking sheet for 15–20 minutes.
- Campfire method: Place packets on hot coals for 10–15 minutes, rotating occasionally.
5. Serve
- Carefully open foil (steam will escape!) and serve burgers on buns or on their own.
- Garnish with fresh parsley or thyme if desired.
⭐ Tips & Variations
- Add a slice of crispy bacon in the packet for extra flavor.
- For a cheesier version, mix Swiss with cheddar or Gruyère.
- You can throw in sliced bell peppers or zucchini for extra veggies.
- Use parchment paper inside foil for easier cleanup.
If you want, I can also give a one-pan skillet version that mimics the foil packet style without needing aluminum foil — quicker for weeknight dinners.
