Steak and Potatoes in Foil Packet: Tender Grill-Packed Dinner

If you love camping, cooking in foil is one of the easiest and most satisfying ways to make dinner. These Steak in Foil Packets are perfect for the campsite: tender yellow potatoes, onions, mushrooms and garlicky butter-soaked beef combine into a classic steak-and-potatoes meal that everyone will enjoy.

What is Steak in Foil Packets?

Foil-wrapped campfire meals are a time-tested way to cook over an open flame with minimal fuss and cleanup. When you prep foil packets in advance and keep them chilled, you simply toss them on the coals or a grill when it’s time to eat. Each packet can be customized, which makes this method ideal for families or picky eaters.

Steak in Foil Packets literally means steak, potatoes and vegetables wrapped in heavy-duty aluminum foil and cooked together. Cut the steak into roughly 1-inch pieces so it heats quickly and can be eaten straight from the packet. Add potatoes, bell peppers, green beans or any vegetables you like. These packets are hearty on their own or pair beautifully with seafood foil packs for a surf-and-turf camp meal.

Ingredients Needed

• Idaho Dutch Yellow potatoes — tender and hold up well in foil
• Onion — sliced thin
• Mushrooms — sliced
• Garlic — fresh or dried
• Cooking oil — your preferred oil
• Salt
• Thyme
• Paprika — smoked paprika adds depth
• Steak seasoning
• Sirloin steak — or substitute London broil
• Butter — for richness and moisture
• Parmesan cheese — grated
• Parsley — freshly minced for garnish

How to Make Steak and Potatoes in Foil

Begin by prepping all the fillings. Dice the potatoes and slice the vegetables so pieces are similar in size for even cooking. Combine potatoes, mushrooms and onions in a bowl, drizzle with oil and toss with salt, thyme, paprika and steak seasoning.

Lay out 12-inch sections of heavy-duty foil. Divide the potato mixture across the foil sheets, then place the steak pieces on top and add a pat of butter to each packet. The butter melts during cooking, keeping the steak and vegetables moist.

How to Make Steak Foil Packs

Fold the foil around the ingredients and crimp the edges to create a sealed packet.

Place the packets on a grill grate or at the edge of a campfire, using indirect heat if possible. Cook until potatoes are fork-tender and the steak reaches your preferred doneness — about 135°F for medium-rare. Rotate the packets occasionally to ensure even cooking.

Foil packets lock in moisture, which keeps the steak juicy and prevents potatoes from drying out. If you change oils or fats, account for that in the total moisture and seasoning.

With the packets sealed and the fire ready, cooking is simple. Keep an eye on the coals and adjust placement as needed so the packets don’t scorch.

What to Serve with Steak and Potatoes

Steak and potatoes are a versatile base. Add mushrooms, Yukon gold potatoes, green beans, sweet potatoes, asparagus or seafood to the packets. You can also serve them alongside a simple salad or crusty bread for a fuller meal.

Leftovers and Reheating

Store leftover packets in the refrigerator by re-rolling the foil or placing packets into an airtight container. Reheat over a flame for best texture, or use a microwave when convenient. Reheating over coals or a grill restores some of the campfire flavor.

Notes

Cut potatoes into equal portions so they cook evenly.

If you don’t have fresh garlic, 1 teaspoon dried garlic (divided) works fine.

Substitute or add umami-rich seasonings like shiitake mushroom powder or a bold spice blend for extra depth of flavor.
