  • Separate and spread out 4 12x12 sheets of aluminum foil. Divide the steak and potato mixture evenly out onto the center of each foil sheet. Wrap the foil up tightly around the contents of the packets, seal them well.
  • Over high heat, grill the foil packets for 10-12 minutes. Flip and grill an additional 10-12 minutes.
  • Open the packets, let them cook an extra two minutes, and garnish with the fresh thyme leaves, serving immediately.

Notes

  • Want a more complete dinner? You can add some fresh broccoli florets or some freshly snapped green beans. They’ll sauté up nicely while absorbing all the flavor.
  • You could also add sliced onions and peppers or sliced mushrooms to these packets as well for more veggie action.
  • Feel free to adjust the seasoning to suit your tastes.
  • Don't skip parboiling the potatoes. Parboiling them makes sure they will cook enough to be done at the same time as the steak.
