Ingredients Notes For Garlic Butter Steak and Potato Foil Packets:

  • Steak: Choose a tender cut like sirloin or ribeye, cut into bite-sized pieces for even cooking.
  • Potatoes: Baby potatoes or diced regular potatoes work best, ensuring they cook through evenly.
  • Garlic Butter: A mix of melted butter, minced garlic, and herbs for drizzling over the steak and potatoes before sealing the packets.
  • Seasonings: Salt, pepper, and your choice of dried herbs (like rosemary, thyme, or oregano) to taste.
  • Vegetables: Optional additions like sliced onions, bell peppers, or mushrooms can add flavor and variety.

Recipe Steps:

  1. Prep Ingredients: Preheat your grill to medium-high heat or your oven to 425°F (220°C). Cut steak and potatoes into bite-sized pieces. Mix the melted butter with minced garlic and herbs.
  2. Assemble Packets: Tear off 4 large sheets of aluminum foil. Divide the steak and potatoes evenly among the sheets, placing them in the center. Drizzle with the garlic butter mixture and season with salt and pepper. If using additional vegetables, add them now.
  3. Seal Packets: Fold the foil over the ingredients, sealing the edges tightly to form a packet. Ensure there’s a little space inside for steam to circulate.
  4. Cook: Place the foil packets on the grill or in the oven. Cook for about 20-25 minutes, or until the steak is cooked to your liking and the potatoes are tender.
  5. Serve: Carefully open the packets (watch out for steam) and serve immediately. Garnish with fresh herbs if desired.

Storage Options:

  • Prep Ahead: Assemble the foil packets ahead of time and store them in the refrigerator for up to a day before cooking.
  • Leftovers: Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave.
