Prepare the Ingredients:
Slice potatoes, carrots, and onions evenly so they cook at the same rate. Divide the meat into equal portions if making individual packets.
Assemble the Foil Packets:
Lay out large sheets of foil. Layer potatoes first, then carrots and onions. Place meat on top and season generously with salt, pepper, and optional spices. Add butter or oil for moisture.
Seal the Packets:
Fold foil tightly around the ingredients, sealing edges well while leaving a little space inside for steam to circulate.
Cook the Hobo Dinner:
Oven: Bake at 375°F (190°C) for 45–60 minutes
Grill: Cook over medium heat for 40–50 minutes, turning once
Campfire: Place on hot coals and cook until vegetables are tender and meat is cooked through
Add Cheese (Optional):
Open packets during the last 5 minutes, sprinkle cheese on top, and reseal loosely to melt.
Rest & Serve:
Let packets rest for a few minutes before opening. Serve directly from foil or plate carefully.
