Ingredients Notes

The beauty of this recipe lies in its simple, yet high-impact ingredients. Each one plays a key role in delivering flavor and texture.

Steak: I recommend using sirloin or ribeye, as they stay juicy and tender inside the foil. If you prefer a leaner option, flank steak works well too, but be sure to slice it thinly for even cooking.

Potatoes: Small Yukon gold or red potatoes are ideal since they have a creamy texture and hold their shape well. Cut them into bite-sized pieces so they cook at the same rate as the steak.

Garlic Butter Sauce: Melted butter infused with fresh minced garlic and a touch of Italian seasoning creates the ultimate savory coating for the steak and potatoes.

Vegetables: While optional, sliced bell peppers, onions, or mushrooms can add a delicious extra layer of flavor and texture.

Foil: Heavy-duty foil is best for this recipe to prevent tearing and ensure even cooking.

How To Make This Garlic Steak & Potato Foil Packets Recipe

Making these foil packets couldn’t be easier! Here’s how to do it step by step.

Start by preheating your grill to medium heat (about 400°F) or your oven to 425°F. If you're cooking over a campfire, wait until the flames die down and you have glowing embers.

Next, prepare the steak and potatoes. Cut the steak into 1-inch cubes and the potatoes into small, even-sized pieces. This ensures that everything cooks at the same rate.

In a mixing bowl, toss the steak and potatoes with melted garlic butter, salt, black pepper, and Italian seasoning. If adding veggies, mix them in now to coat them with all that delicious flavor.

Lay out four large sheets of foil and divide the mixture evenly among them. Fold up the edges and seal the packets tightly, ensuring no juices escape while cooking.

Place the foil packets on the grill or in the oven and cook for 20-25 minutes, flipping halfway through if grilling. You’ll know they’re done when the potatoes are fork-tender and the steak reaches your desired doneness.

Carefully open the foil packets (watch out for steam!) and garnish with fresh parsley or grated Parmesan cheese for an extra touch of flavor.

Storage Options

If you have leftovers, you can store them in an airtight container in the refrigerator for up to 3 days. The steak and potatoes reheat well in the oven at 350°F for 10-15 minutes, or you can warm them up in a skillet over medium heat with a little extra butter.

Freezing is possible, but the potatoes may become a bit softer upon reheating. If freezing, store the cooked foil packets in freezer-safe bags for up to 2 months, and thaw overnight in the fridge before reheating.

Variations and Substitutions

The versatility of this recipe allows for endless possibilities. Here are a few ways to make it your own:

Change Up the Protein – Swap the steak for chicken, shrimp, or sausage to create a completely different meal while keeping the same easy prep method.

Add More Veggies – Try adding zucchini, asparagus, or cherry tomatoes for extra freshness and color.

Make It Spicy – Toss in a pinch of red pepper flakes or Cajun seasoning for a little heat.

Go Low-Carb – Substitute the potatoes with cauliflower florets to keep it keto-friendly without sacrificing flavor.
