Can I prepare foil packets ahead of time?
Yes. Assemble packets up to 4 hours ahead, refrigerate, then grill when ready. Add an extra 2–3 minutes to grilling time if packets are cold.
What temperature and time should I grill these?
Grill over medium heat (about 400°F) for 15–20 minutes, depending on your grill. Potatoes should be fork-tender and beef cooked through.
Can I use a different cheese?
Yes. Cheddar, American, or Monterey Jack work well. Use the same 2-cup amount and add in the last 3–5 minutes of cooking so it melts.
How do I prevent the foil from tearing?
Use heavy-duty foil or double-layer regular foil. Place vegetables and patty in center, fold edges tightly but not so hard you puncture it, and seal all seams.
Can I make these in the oven instead?
Yes. Bake on a sheet pan at 400°F for 25–30 minutes until potatoes are tender and beef is cooked through.
