These Garlic Butter Steak and Potato Foil Packets are an easy family dinner recipe for summer. Cook them on the grill/campfire or in the oven or Air Fryer!
Ingredients
- ▢1 ½ pounds steak sirloin is my favorite cut here
- ▢1 pound baby potatoes cut into ½ inch pieces (halving or quartering usually does it for me)
- ▢1 onion peeled, halved and then thinly sliced
- ▢1 tablespoon olive oil
- ▢2 tablespoons chopped fresh parsley
- ▢1 tablespoon minced garlic or more to taste
- ▢1 tablespoon Italian seasoning
- ▢salt and pepper to taste
- ▢2 tablespoons butter cubed
Instructions
Par-boil the potatoes (highly recommended):
- Place the sliced potatoes in a pot of boiling, salted water and cook for 5 minutes. Drain immediately and place in a large bowl. Allow to sit until cool enough to handle, about 10 minutes.
Make the foil packets:
- Prep the steak: Cut the steak into pieces (2.5 – 3 inches for well done, 3 – 4 inches for medium, 5 inches for rarer steak). Marinate it if you like.
- Combine ingredients: Place the steak, potatoes, onion, olive oil, parsley, garlic, Italian seasoning, salt and pepper in a large bowl and toss well.
- Assemble foil packets: Set out 4 pieces of aluminum foil, at least 12×12 inches. Evenly divide the steak and potatoes between the middles of the foil sheets. Top with butter cubes, then fold the foil over the steak and potatoes and seal well.
- On the grill/fire: On a HOT grill, cook the foil packets for 8-10 minutes per side, or until the potatoes are tender (exact grilling time can vary depending on type of foil used, exact oven temperature, size of steak, etc.! I recommend an oven thermometer to check on the steak after about 10 minutes to gauge how much longer it will need!)If you’re cooking the packets on a fire without a grilling rack, place them on a 2-inch bed of coal.
- In the oven: Bake the steak foil packets at 425°F for around 20 minutes, or until done to your liking (exact baking time can vary depending on type of foil used, exact oven temperature, size of steak, etc.! I recommend an oven thermometer to check on the steak after about 15 minutes to gauge how much longer it will need!). If you want a char on the steaks, open the packets and broil for 1-2 minutes at the end.
- Careful when opening the packets – hot steam and juices ahead!
