👩🍳 Instructions
1️⃣ Prepare the patties
- In a bowl, mix ground beef with salt, pepper, garlic powder, and Worcestershire sauce.
- Form into 4 equal patties (slightly wider than your buns).
2️⃣ Prep the foil packets
- Tear 4 large sheets of heavy-duty aluminum foil.
- Lightly grease each sheet.
- Place one patty in the center of each.
- Top with mushrooms and onions.
- Add a small pat of butter or drizzle olive oil over veggies.
3️⃣ Seal tightly
- Fold foil over and crimp edges to seal completely (keep some space inside for steam).
4️⃣ Cook
- Grill: Medium heat (400°F) for 15–18 minutes.
- Oven: 375°F (190°C) for 20–25 minutes.
- Campfire: Place on hot coals for about 15–20 minutes.
(Internal temp should reach 160°F / 71°C.)
5️⃣ Add cheese
- Carefully open foil (watch steam).
- Place Swiss cheese on each patty.
- Reseal loosely and cook 1–2 more minutes until melted.
6️⃣ Serve
- Place on toasted buns with your favorite toppings.
🔥 Pro Tips
- Add a splash of beef broth inside the packet for extra juiciness.
- For a richer flavor, sauté mushrooms in butter first.
- Want it low-carb? Skip the bun and serve over lettuce or cauliflower mash.
