Ingredients

 For the Burger Packets:

• 1 lb ground beef (form into 4 burger patties)
• Salt & black pepper, to taste
• 1 tsp garlic powder
• 4 slices Swiss cheese
• 1 cup mushrooms, sliced
• 1 tbsp butter
• 1 red bell pepper, sliced into rings
• 1 lb baby potatoes, halved
• 1 tbsp olive oil
• 1 tbsp fresh parsley, chopped (for garnish)
• Optional: 1 clove garlic, minced (for added flavor in mushrooms or potatoes)

Instructions

Step 1: Preheat Your Grill or Oven

• Preheat your grill or oven to 400°F (200°C).

Step 2: Sauté the Mushrooms

• In a small skillet over medium heat, melt 1 tablespoon butter.
• Add sliced mushrooms (and minced garlic if using).
• Sauté for 5–6 minutes, or until mushrooms are golden brown and tender.
• Remove from heat and set aside.

Time: 6 minutes

Step 3: Prep the Potatoes

• In a mixing bowl, toss halved baby potatoes with 1 tbsp olive oil, garlic powder, salt, and pepper.
• Make sure potatoes are well coated. This will help them crisp and soften nicely during cooking.

Time: 3 minutes

Step 4: Assemble the Foil Packets

• Lay out 4 large sheets of heavy-duty foil (about 12×12 inches each).
• In the center of each sheet, place a ring of red bell pepper.
• On top of the pepper ring, place a seasoned ground beef patty (lightly seasoned with salt and pepper).
• Spoon some of the sautéed mushrooms over each patty.
• Top each with a slice of Swiss cheese.
• Arrange a portion of the seasoned baby potatoes around the patty in each packet.

Time: 5 minutes

Step 5: Seal and Cook

• Fold each foil packet tightly: bring the sides up and over the contents, sealing edges to trap steam inside.
• Place on the grill or in the preheated oven and cook for 25–30 minutes, or until:
  • The potatoes are fork-tender
  • The burger patties are fully cooked (160°F internal temp)

Time: 25–30 minutes

Step 6: Serve and Garnish

• Carefully open each foil packet — be cautious of hot steam.
• Sprinkle with fresh chopped parsley before serving.
• Serve right in the foil for easy cleanup, or plate with additional toppings like mustard, pickles, or extra cheese if desired.

Serving Suggestions

• Enjoy with a side of corn on the cob or grilled asparagus.
• Serve with crusty bread or a fresh summer salad.
• Perfect for camping, backyard BBQs, or a no-fuss weeknight dinner.
