Ingredients
- 1 lb ground beef (80/20 recommended)
- 1 tsp garlic powder
- 0.5 tsp salt
- 0.5 tsp black pepper
- 8 oz cremini or button mushrooms, sliced

Instructions
- Step 1: In a mixing bowl, combine the ground beef, garlic powder, salt, and black pepper until evenly mixed.
- Step 2: Lay out a sheet of nonstick foil and place an even portion of the beef mixture in the center. Shape it into a patty, avoiding flattening it too much to keep it juicy.
- Step 3: Place a slice of Swiss cheese on top of the patty. Layer the mushrooms, onions, and bell peppers over the cheese.
- Step 4: If using, toss the optional vegetables with a drizzle of olive oil and a pinch of salt, then add them on top of the meat and veggies in the foil.
- Step 5: Fold the foil tightly around the ingredients to seal each packet securely.
- Step 6: Place the foil packets on a medium-high grill or in a preheated oven at 400°F (200°C).
- Step 7: Cook for approximately 25 minutes or until the burger is cooked through and the vegetables are tender.
- Step 8: Carefully open the packets, watching for escaping steam, and serve hot.
Tips & Variations
- For extra flavor, mix chopped fresh herbs like thyme or parsley into the beef before shaping the patties.
- Use cheddar or provolone if you prefer a different cheese instead of Swiss.
- Try adding a splash of Worcestershire sauce or soy sauce to the meat mixture for a savory boost.
- If grilling, place packets over indirect heat to avoid flare-ups and ensure even cooking.
Storage
Store any leftover burger foil packets in an airtight container in the refrigerator for up to 3 days. To reheat, remove from foil and warm in a skillet over medium heat or use a microwave until hot throughout. Avoid reheating in foil to prevent metal hazards.

FAQs
Can I prepare these foil packets ahead of time?
Yes, you can assemble the foil packets a few hours in advance and keep them refrigerated until ready to cook. Add fresh cheese just before cooking to prevent it from melting prematurely.
Can I use a different type of meat?
Absolutely. Ground turkey, chicken, or even plant-based meat alternatives work well. Adjust cooking times as needed based on the meat used.

Instructions
- Prepare the Meat Mixture: In a mixing bowl, combine the ground beef, garlic powder, salt, and black pepper thoroughly to evenly distribute the seasonings.
- Form Patties on Foil: Lay out a sheet of nonstick foil and place a portion of the beef mixture in the center. Shape it gently into a patty without flattening too much to retain juiciness.
- Add Cheese and Vegetables: Top each patty with a slice of Swiss cheese. Then layer mushrooms, sliced onions, and bell peppers evenly over the cheese.
- Prepare Optional Vegetables: If using optional vegetables, drizzle them with olive oil and season as desired, then add them on top of or alongside the burger ingredients in the foil.
- Seal Foil Packets: Fold the foil tightly around the ingredients to seal completely, ensuring no steam escapes during cooking.
- Cook the Packets: Place the sealed foil packets on a medium-high grill or in a preheated oven at 400°F (200°C). Cook for about 25 minutes, or until the beef is fully cooked and vegetables are tender.
- Serve: Carefully open the foil packets to avoid escaping steam and serve the burgers hot for the best flavor and juiciness.
Notes
- You can adjust the fat content of the ground beef to your preference, but an 80/20 ratio is recommended for juiciness.
- Soaking potatoes or sweet potatoes in cold water before cooking helps remove excess starch and improves texture.
- If grilling, ensure the grill heat is medium-high and the foil packets are sealed tightly to prevent flare-ups.
- The recipe is versatile with optional vegetables; feel free to swap in your favorites for a personalized touch.
- Use nonstick foil to prevent sticking and ease cleanup.
