Grilled steak, potato, and mushroom foil packs are filled with tender cuts of ribeye steak, slices of yellow or red potatoes, and mushrooms with lots of flavor! Perfect for camping!

These steak foil packs are amazing for camping out, but they can also just as easily be made at home during the week.
Especially if you’re a planner and want to make them the day before so that you can easily toss them on the grill the next day.
Another great camping recipe is my grilled chicken & asparagus foil packs or cast-iron skillet flank steak to make on a grill or open fire.

How to Make Steak, Potato, and Mushroom Foil Packs
It’s all in the prep!
Slice the steak into ½″ strips against the grain or in 2″ pieces (whichever you prefer), slice the potatoes and mushrooms, then place it all in a bowl.
In another bowl, add all of the seasoned butter ingredients and whisk it together. Then add it to the steak bowl, stir to combine.
The seasoned butter is thick and can be hard to stir, but the idea is that it is spread all over the steak and veggies so that when it cooks it melts over them.
Lay out six 12″x12″ pieces of foil. Divide the steak and veggies evenly onto each.
Wrap the sides around it and be sure nothing can leak out while it’s cooking.
Heat the grill to a high heat around 425 degrees Fahrenheit.
Once the grill is up to temperature, place foil packets on the grill for 6 minutes, flip, and cook an additional 6 minutes. Be careful while flipping so that the foil packs do not come undone.

Are far ahead could they be made or can they be froze and cooked later.
I recommend making them ahead no more than 3 days as uncooked steak does not last very long in the refrigerator.
I do not recommend freezing them withe the potatoes because they do not thaw very well after being frozen. They contain a lot of water and when they thaw this causes the potatoes to become mushy and grainy.
Would I put these packets in a 425’ oven for 12 min.? Do I need to turn them in the oven?
Hi Jackie,
If you plan to cook the foil packets in the oven I recommend 425 degrees for 20-25 minutes. They take just a little longer than a grill and do not require flipping.
