Ingredients
  

  • 2 pounds steak cubed (sirloin or your favorite cut): Trim sinew for tender bites.
  • 2 pounds red potatoes cut into bite-size pieces: Par cook for about 5 minutes.
  • 2 jalapenos finely chopped: Adjust quantity for desired heat; remove seeds for less spice.
  • 6 tablespoons butter salted, softened: Forms the base of the garlic butter sauce.
  • 2 tablespoons parsley chopped: Adds freshness and color.
  • 2 teaspoons salt: Essential for seasoning.
  • 2 teaspoons black pepper: Adds a bit of heat and depth.
  • 2 teaspoons granulated garlic: Enhances the garlic flavor.
  • 1 tablespoon Worcestershire sauce: Adds umami and depth.
  • 4 sprigs rosemary about 2 inches in length: Optional; adds a fragrant, earthy aroma.

Instructions
 

  • Cube the steak into bite-size pieces, trimming any sinew. Cut the red potatoes into bite-size pieces and par cook them for 5 minutes.
  • Lay out four 14x18-inch pieces of aluminum foil. Divide the steak and potatoes evenly among the foil sheets.
  • Sprinkle chopped jalapenos over the steak and potatoes. Adjust the amount based on your spice preference.
  • In a small bowl, whisk together softened butter, chopped parsley, salt, pepper, granulated garlic, and Worcestershire sauce. Divide the mixture among the foil packs, spooning it over the steak and potatoes.
  • Place a sprig of rosemary on top of each foil pack. Fold the edges of the foil to create sealed packets.
  • For oven cooking, preheat to 375°F (190°C) and bake for 25-30 minutes. For grilling, preheat to 400°F (200°C) and grill for 15-20 minutes.
  • Check for doneness by carefully opening one packet. Cook an additional 5-7 minutes if needed for well-done steak.
  • Serve the foil packs directly from the foil or transfer to plates. Garnish with additional parsley if desired.

Notes

  • Vegetable Additions: Add mushrooms, bell peppers, or onions. Par cook root vegetables like carrots with the potatoes.
  • Spice Levels: Adjust the heat by adding more or fewer jalapenos.
  • Different Herbs: Substitute rosemary with thyme or oregano.
  • Healthier Options: Use less butter or olive oil instead, and swap red potatoes for sweet potatoes.
  • Storage and Reheating: Store leftovers in an airtight container for up to 3 days. Reheat in the oven or microwave.
