Creating Garlic Steak and Potato Foil Packs is straightforward if you follow these step-by-step instructions:

1. Preheat Your Grill or Oven: If cooking on a grill, preheat it to medium-high heat. For the oven, preheat it to 400°F (200°C).

2. Prepare the Foil: Cut four large pieces of heavy-duty aluminum foil, about 12-18 inches each.

3. Slice the Steak: Cut the steak into bite-sized pieces for quicker cooking.

4. Combine Ingredients: In a large bowl, toss the steak pieces, halved baby potatoes, minced garlic, olive oil, rosemary, thyme, and season with salt and pepper.

5. Assemble the Foil Packs: Divide the steak and potato mixture among the four pieces of foil. Fold the foil over to create sealed packets, pinching the edges tightly to prevent leakage.

6. Cook the Packs: Place the foil packs on the grill or in the oven. Cook for 20-25 minutes, or until the steak is cooked to your desired doneness and the potatoes are tender.

7. Check for Doneness: Carefully open one foil pack to check if the potatoes are fork-tender and the steak is cooked through.

8. Serve: Remove the foil packs from the grill or oven and let them cool for a minute. Then, carefully open them, allowing the steam to escape.

9. Garnish: If desired, sprinkle fresh chopped parsley over the top before serving.
