Creating Garlic Steak and Potato Foil Packs is simple, and following these steps will guarantee delicious results:

1. Preheat Oven or Grill: If you are using an oven, preheat it to 400°F (200°C). If grilling, prepare the grill for medium-high heat.

2. Prepare the Ingredients: In a large bowl, combine the flank steak, halved potatoes, minced garlic, olive oil, salt, black pepper, paprika, rosemary, and thyme. Toss until everything is evenly coated.

3. Cut the Foil: Tear off sheets of aluminum foil, about 12×18 inches in size. This will be enough to fold over and seal the ingredients.

4. Divide the Mixture: Place an equal portion of the steak and potato mixture in the center of each foil sheet.

5. Seal the Packets: Fold the sides of the foil over the ingredients and crimp them tightly to ensure no steam escapes.

6. Cooking Options:
– Oven: Place the foil packs on a baking sheet and bake for 35-40 minutes or until the steak is cooked to your liking and potatoes are tender.
– Grill: Place the foil packs directly on the grill and cook for the same amount of time.

7. Carefully Open: After cooking, carefully open the foil packs, avoiding steam burns.

8. Garnish and Serve: Sprinkle fresh parsley over the contents before serving for a touch of flavor and color.
