For Grilling:
Place the foil packets directly on the preheated grill grates.
Cook for 10 to 12 minutes per side, turning once halfway through. Total cook time will be about 20 to 25 minutes, depending on the size of the steak cubes and how well done you prefer your meat.
For Oven Baking:
Place the packets on a baking sheet to catch any drips.
Bake at 425°F (220°C) for 20 to 25 minutes, then open one packet carefully to check for doneness.
If the potatoes are tender and the steak is cooked to your liking, they are ready. For a more caramelized finish, open the packets slightly and broil for 2–3 minutes.
For Campfire Cooking:
Place packets on the hot embers (not directly on flames) and cook for 20–25 minutes, flipping halfway through.
Use tongs to handle and check the packets.
Step 7: Finish and Serve
Carefully open each foil packet (use caution as the steam will be very hot).
Drizzle with extra melted butter or garlic butter if desired.
Sprinkle with fresh parsley and a squeeze of lemon juice for brightness.
Serve directly in the foil for easy cleanup, or transfer to plates for a more formal presentation.
Tips and Variations
Choosing the Steak: Sirloin, ribeye, or strip steak work best because they stay tender and juicy even when cooked in foil. Avoid lean cuts like round or flank, which can become tough.
Add Vegetables: You can include sliced bell peppers, mushrooms, or green beans for extra color and nutrition. Add them raw along with the steak and potatoes.
Cheesy Option: After cooking, sprinkle freshly grated Parmesan or shredded cheddar over the top and let it melt into the hot food.
Herb Substitutions: Try swapping Italian seasoning for Cajun spice, steak seasoning, or a mix of rosemary and thyme for a more earthy flavor.
Make Ahead: Assemble the packets up to one day in advance and refrigerate. Cook directly from the refrigerator, adding an extra few minutes to the cooking time.
Crispier Potatoes: For a crisp texture, open the foil packets for the last 5 minutes of cooking and broil or increase the grill heat slightly.
Serving Suggestions
Garlic Steak and Potato Foil Packets can be served as a complete meal, but you can also add:
A side salad with vinaigrette or coleslaw for freshness
Grilled corn on the cob or asparagus
Warm bread or dinner rolls to soak up the garlic butter
A glass of red wine or iced tea for pairing
This recipe is flexible, making it perfect for weeknight dinners, camping trips, or outdoor cookouts. The individual packets make serving easy and help keep cleanup minimal.
Storage and Reheating
Refrigerate leftovers in airtight containers for up to 3 days.
To reheat, place the foil packet back in the oven at 350°F (175°C) for 10–15 minutes or until warmed through.
You can also reheat the contents in a skillet over medium heat with a little butter to restore moisture.
Avoid microwaving in foil; transfer to a microwave-safe dish first.
Notes
Cooking times can vary depending on the thickness of the steak and the size of the potato pieces. For best results, aim for an internal temperature of 135°F (57°C) for medium-rare or 145°F (63°C) for medium steak. Always allow the packets to rest for a few minutes before opening so the juices redistribute and the flavors deepen.
