Ingredients

For the Steak and Potatoes:

  • 2 lbs (900g) flank steak, cut into strips

  • 2 lbs (900g) baby Yukon potatoes, washed and quartered

  • 2 tablespoons fresh parsley, finely chopped

  • 1/2 cup butter, melted

  • 4 cloves garlic, finely minced

  • 1 teaspoon Italian seasoning

  • Juice of 1/2 lemon

  • 1 teaspoon crushed red chili pepper flakes (optional)

  • 1 teaspoon salt and freshly cracked pepper, to taste

  • 1 tablespoon grated parmesan, for garnish

For the Steak Marinade:

  • 2/3 cup low-sodium soy sauce (or coconut amino)

  • 1/4 cup olive oil

  • 1 tablespoon hot sauce (optional, Sriracha works well)

  • 1 small crumbled bouillon cube (optional)

Directions

  1. Prepare the Marinade:
    In a bowl or Ziploc bag, combine soy sauce, hot sauce, olive oil, and the optional bouillon cube. Add the steak strips and mix to coat. Let marinate in the refrigerator for at least 30 minutes (or up to overnight).

  2. Prepare the Garlic Butter Sauce:
    In a small bowl, combine melted butter, lemon juice, fresh parsley, minced garlic, Italian seasoning, and crushed red chili pepper flakes (if using). Mix well and set aside.

  3. Assemble the Foil Packs:
    Preheat your oven to 430°F (220°C). Tear four 15-inch (40 cm) pieces of heavy-duty foil.
    Divide the marinated steak strips and quartered potatoes evenly onto the foil sheets. Drizzle the garlic butter sauce generously over the steak and potatoes. Season with salt and pepper.

  4. Seal and Cook:
    Fold the sides of the foil over the steak and potatoes, pressing tightly to seal the packets. Place the foil packs on a baking sheet or tray and bake for 20-25 minutes.
    For extra flavor, you can open the foil packs carefully and broil for 3-4 minutes to get a slight char.

  5. Serve:
    Open the foil packs, sprinkle with grated parmesan, and garnish with additional fresh parsley. Serve warm and enjoy!

Why Garlic Butter Steak & Potato Foil Packs are Perfect for Any Occasion

One of the standout features of Garlic Butter Steak & Potato Foil Packs is their versatility. This recipe is adaptable for any cooking method—whether you’re cooking in the oven, on the grill, or even over a campfire, the result is the same: tender, flavorful steak and crispy potatoes wrapped in savory garlic butter. The foil packs keep the ingredients sealed in, ensuring the flavors meld together and that the steak remains juicy while the potatoes develop a crisp, caramelized edge.

The ease of preparation also makes this dish an excellent choice for any meal occasion. Whether it’s a busy weeknight or a casual weekend BBQ, Garlic Butter Steak & Potato Foil Packs are incredibly simple to assemble. All you need to do is prepare the marinade for the steak, toss the potatoes in the garlic butter sauce, and assemble the packs. From there, it’s just a matter of cooking them to perfection. The simplicity of the recipe means you can focus on other parts of your meal or simply enjoy your time outdoors while the foil packs cook.

The foil pack method also means minimal clean-up. Once the meal is cooked, you simply open the foil, enjoy the food, and discard the used foil. This makes it a great option for those who want a stress-free meal without a pile of dirty dishes afterward.

The Flavor Profile of Garlic Butter Steak & Potato Foil Packs

The flavor profile of Garlic Butter Steak & Potato Foil Packs is a harmonious blend of savory, tangy, and aromatic elements. The marinade for the steak combines soy sauce, olive oil, and hot sauce (optional), providing a rich, umami base that enhances the natural flavors of the meat. Soy sauce lends a salty, savory depth, while olive oil helps to tenderize the steak and keep it juicy.

The garlic butter sauce is where the dish really shines, with minced garlic, Italian seasoning, and fresh parsley creating a fragrant, herby base that pairs perfectly with both the steak and the potatoes. The addition of lemon juice adds a zesty, refreshing contrast to the richness of the butter, while the crushed red chili pepper flakes (if used) offer a subtle heat that makes the dish even more exciting. The sprinkle of Parmesan at the end adds a sharp, nutty flavor that rounds out the dish beautifully, providing a satisfying finish.

The combination of crispy potatoes, savory steak, and the rich garlic butter sauce creates a well-balanced dish that appeals to a wide range of tastes. The slight tang of lemon and the warmth of the chili flakes elevate the flavor profile, while the fresh parsley brings brightness and a pop of color. Every bite is full of flavor, and the tenderness of the steak paired with the crispy potatoes makes for a delicious and satisfying meal.

The Benefits of Cooking with Flank Steak and Potatoes

Flank steak is an excellent choice for this recipe because it’s lean yet flavorful, and it cooks quickly, making it ideal for foil pack meals. Flank steak is a relatively affordable cut of beef, making it a great option for families or those on a budget. When marinated properly, flank steak becomes tender and absorbs all the flavors of the marinade, which helps enhance the dish’s overall taste.

The potatoes used in this recipe are baby Yukon gold potatoes, which are known for their creamy texture and slightly sweet flavor. They cook perfectly alongside the steak, absorbing the garlic butter sauce while developing a golden, crispy crust. Yukon gold potatoes have a natural waxiness that helps them retain moisture and crisp up nicely when roasted, creating the perfect contrast to the tender steak.

Together, the flank steak and potatoes create a hearty, satisfying meal that provides a balanced source of protein and carbohydrates, making it a great option for those looking for a filling yet healthy meal.

How to Customize Garlic Butter Steak & Potato Foil Packs

One of the best things about Garlic Butter Steak & Potato Foil Packs is their adaptability. You can easily modify this recipe to suit your tastes or dietary preferences. For those who prefer a spicier dish, you can increase the amount of hot sauce in the marinade or add more crushed red chili flakes to the garlic butter sauce. For a smoky flavor, consider adding a teaspoon of smoked paprika to the garlic butter mixture.

If you’re looking for a vegetarian version, you can replace the steak with hearty vegetables like portobello mushrooms, zucchini, or bell peppers. These vegetables will absorb the garlic butter sauce just like the steak, providing a savory base while maintaining a lighter profile. You can also add other vegetables like onions, carrots, or Brussels sprouts to the foil packs to increase the dish’s nutritional value and add more depth of flavor.

To make the dish even healthier, you can substitute the butter with olive oil or use a lighter alternative like avocado oil. This will provide a different flavor profile while still keeping the dish flavorful and satisfying.

Cooking Garlic Butter Steak & Potato Foil Packs on the Grill

One of the standout features of this recipe is that it can be cooked on the grill, making it a perfect option for BBQs or summer cookouts. Grilling the foil packs adds a smoky flavor to the meat and potatoes, enhancing the overall taste and making the dish even more flavorful. When cooking on the grill, be sure to keep an eye on the temperature to avoid overcooking the meat or burning the potatoes. Medium heat is ideal, as it allows the food to cook through without getting too charred on the outside.

Grilling also adds a beautiful sear to the steak, which can create an additional layer of flavor and texture. If you prefer a slightly crispy exterior on your steak, you can open the foil packs during the last few minutes of grilling to allow the steak to get a bit of char.

Making Garlic Butter Steak & Potato Foil Packs for Meal Prep

Garlic Butter Steak & Potato Foil Packs are also great for meal prep. You can prepare the foil packs in advance, store them in the refrigerator, and cook them when you’re ready to eat. The potatoes and steak will stay fresh and flavorful in the fridge for up to two days. This makes them a perfect option for busy individuals who need a quick, easy, and delicious meal that can be prepared ahead of time.

For those looking to save even more time, you can make the foil packs in bulk, store them in the freezer, and cook them directly from frozen. Just be sure to allow for a slightly longer cooking time if you’re cooking from frozen, but the results will be just as tasty and satisfying.
