Make dinner completely effortless with these juicy steak and potato foil packs! Loaded with garlic butter and roasted to perfection on the grill or in the oven.
Preheat the grill to medium high heat (about 400°F) or preheat the oven to 425°F. Cut 4 large sheets (about 12 x 12 inches) of heavy duty aluminum foil.
In a large mixing bowl, add the cubed sirloin steak, halved baby potatoes, and chopped yellow onion.
Add the olive oil and season with garlic powder, onion powder, dried thyme, kosher salt, and black pepper. Toss well to combine.
Divide the seasoned steak and potato mixture equally among the 4 squares of foil, making a pile in the center of each square.
Top each pile with 1 tablespoon (1 slice) of butter.
Lift the two longest opposite sides of the foil over the food. Fold the edges over several times to seal the foil, leaving a little room for the steam to build inside. Roll the remaining two open sides of the foil tightly to seal the packet completely.
Grill the foil packs or place them on a baking sheet in the oven. Cook for 20 to 25 minutes, or until the potatoes are fork-tender.
Carefully remove from the heat and let sit for 5 minutes.
Carefully open the foil packets with a fork to release the steam. Garnish with fresh parsley and serve immediately.
