Ingredients

2 pounds lean sirloin steak, trimmed of excess fat and cut into 2-inch chunks
1 pound baby yellow potatoes, halved or quartered depending on size
3 tablespoons olive oil
1 tablespoon minced garlic (adjust to taste)
2 teaspoons Italian seasoning
- or a blend of dried oregano, thyme, and parsley
1 teaspoon onion powder
Salt and freshly ground black pepper, to taste

Step-by-Step Instructions

1. Preparation

If you are baking the foil packets, preheat your oven to 425°F (220°C).
If grilling, preheat your grill to high heat and lightly oil the grates to prevent sticking.

2. Mix and Season

In a large mixing bowl, combine the steak chunks and baby potatoes. Drizzle with olive oil, then add the minced garlic, Italian seasoning, onion powder, salt, and freshly ground black pepper.

Toss gently until all ingredients are evenly coated with the oil and seasonings. This step ensures that every bite is flavorful.

For even deeper flavor, you can allow the mixture to marinate for 15–30 minutes, though it is not required.

3. Assemble the Foil Packets

Lay out four large aluminum foil sheets, approximately 12×12 inches each, on a flat surface.

Evenly divide the steak and potato mixture among the foil sheets, placing it in the center of each one. Fold the foil over the contents and seal the edges tightly to form secure packets. Make sure there are no gaps to prevent juices from leaking out during cooking.

Cooking Methods

Grilling Instructions

Place the sealed foil packets directly over high heat on the grill.
Grill for approximately 10 minutes per side, flipping once.
Cooking time may vary depending on grill temperature and how well done you like your steak.
Carefully remove the packets from the grill and let them rest for 5 minutes before opening.

Oven Baking Instructions

Place the foil packets on a baking sheet.
Bake in the preheated oven at 425°F (220°C) for 25–30 minutes, or until the potatoes are fork-tender and the steak is cooked to your preferred doneness.
For a lightly browned finish, carefully open the packets and broil for 2–3 minutes.

Serving Ideas

These steak and potato foil packets are delicious on their own, but you can elevate them even more with:

Fresh chopped parsley or thyme
A small pat of garlic butter
Grated Parmesan cheese
A squeeze of fresh lemon juice

Serve with a simple green salad, roasted vegetables, or crusty bread for a complete meal.

Helpful Tips and Variations

Cut steak and potatoes into similar-sized pieces for even cooking.
Add mushrooms, bell peppers, onions, or green beans for extra vegetables.
Swap sirloin for ribeye or strip steak for a richer flavor.
Add crushed red pepper flakes for a spicy kick.
Always open foil packets carefully to avoid hot steam burns.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheat in the oven at 350°F (175°C) or in a skillet over medium heat until warmed through.
