Can I use a different kind of ground meat?

Yes! Ground turkey or chicken works, but you may want to add a little extra seasoning and a drizzle of oil since they’re leaner. The magic of Mushroom And Swiss Burger Foil Packets is that the steam helps keep things moist, but lean meats appreciate a little support.

How do I keep potatoes from being undercooked?

Slice them thin (think: coin-sized and not chunky), and consider giving them a quick soak in cold water if prepping ahead. Dry them well before adding so they roast-steam instead of turning soggy.

Can I prep these ahead of time?

You sure can. Assemble the packets, refrigerate, and cook within 24 hours for best texture. If you’re using potatoes, keep them soaked separately, then add right before cooking.

How do I store leftovers?

Let everything cool, then store in an airtight container in the fridge for up to 3 days . Reheat in the oven (covered) or microwave gently. The mushrooms and onions usually taste even better the next day—like they had time to think about how delicious they are.

Can I cook Mushroom And Swiss Burger Foil Packets on a campfire?

Yes! Place packets on hot coals (not direct flames) and cook, turning occasionally. Timing varies, but start checking around 20–25 minutes .

Cook Mode Prevent your screen from going dark

Instructions

Preheat oven to 400°F (200°C) or heat grill to medium-high.
In a mixing bowl, combine ground beef, garlic powder, salt, and pepper. Mix just until combined.
Lay out 4 sheets of foil. Divide beef mixture evenly and shape into thick patties in the center of each sheet.
Place one slice of Swiss cheese on each patty.
Top with mushrooms, onions, and bell peppers.
Toss optional vegetables with olive oil, salt, and pepper. Add around or on top of patties.
Fold foil tightly to seal each packet, leaving a little space inside for steam circulation.
Place packets on a baking sheet (for oven) or directly on grill grates.
Cook for about 25 minutes, or until burgers reach 160°F internally and vegetables are tender.
Carefully open packets (steam will escape) and serve hot.

Notes

Slice potatoes thin to ensure even cooking.

For extra flavor, add a splash of Worcestershire sauce to the beef mixture.

You can prep the packets up to 24 hours in advance and refrigerate before cooking.

Double-wrap packets if grilling to prevent leaks.

Leaner beef may cook slightly faster and be less juicy.
