Creating Garlic Steak and Potato Foil Packs is simple when you follow these steps:

1. Preheat Oven or Grill: Preheat your oven to 400°F (200°C) or prepare a grill for medium-high heat.
2. Prepare Foil Sheets: Cut large sheets of aluminum foil, about 18 inches long, placing each sheet on a flat surface.
3. Season the Steak: In a bowl, combine the olive oil, minced garlic, paprika, salt, pepper, and Italian herbs. Mix thoroughly.
4. Coat the Steak: Add the flank steak to the bowl, ensuring it’s evenly coated with the marinade. Let it sit for a few minutes.
5. Assemble the Packs: In the center of each foil sheet, place a portion of the diced potatoes. Top with the marinated steak.
6. Seal the Foil Packs: Fold the sides of the foil over the potatoes and steak, creating a sealed pouch. Make sure they are tightly packed to keep the juices from leaking.
7. Cook: Place the foil packs on a baking sheet if using the oven, or directly on the grill. Cook for 30–35 minutes, or until the steak reaches your desired level of doneness and the potatoes are tender.
8. Check for Doneness: After cooking, carefully open one pack to check if the steak and potatoes are cooked to your liking. If needed, reseal and cook for an additional 5–10 minutes.
9. Serve: Once cooked, carefully unwrap the packs to avoid steam. Garnish with fresh parsley before serving.
