Garlic Steak & Potato Foil Packets

Servings: 4

Prep Time: 15 minutes

Cook Time: 30-35 minutes

Total Time: 45-50 minutes


  • 1.5 pounds sirloin steak, cut into 1-inch cubes
  • 1 pound baby potatoes, quartered
  • 3 tablespoons olive oil
  • 4 tablespoons unsalted butter, melted
  • 4 cloves garlic, minced
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • Salt and pepper to taste
  • Fresh parsley, chopped (for garnish)


Step 1: Preheat and Prep

Preheat your grill to medium-high heat or your oven to 425°F (220°C). Cut four large pieces of aluminum foil, each about 12×18 inches, and set them aside.

Step 2: Prepare the Ingredients

In a large bowl, combine the steak cubes and quartered baby potatoes. Drizzle with olive oil, then add minced garlic, dried thyme, dried rosemary, salt, and pepper. Toss to coat everything evenly.

Step 3: Assemble the Packets

Divide the steak and potato mixture evenly among the four pieces of aluminum foil. Drizzle the melted butter over the top of each packet. Fold the foil over the steak and potatoes, sealing the edges tightly to create a packet.

Step 4: Cook the Packets

Grill Method: Place the foil packets on the preheated grill, cooking for about 10-15 minutes on each side, or until the steak is cooked to your desired level of doneness and the potatoes are tender.

Oven Method: Place the foil packets on a baking sheet and bake in the preheated oven for 30-35 minutes, or until the steak is cooked through and the potatoes are tender.

Step 5: Serve

Carefully open the foil packets, allowing the steam to escape. Sprinkle fresh parsley over the top for a burst of color and freshness. Serve the packets directly on plates or transfer the contents to a serving dish. Enjoy!

Variations & Tips


  1. Vegetable Additions: Add in vegetables like bell peppers, onions, or zucchini for extra flavor and nutrition.
  2. Cheese Finish: Sprinkle some shredded cheese, such as Parmesan or cheddar, over the hot packets before serving.
  3. Spice it Up: Add a pinch of red pepper flakes or a dash of hot sauce for a spicy kick.


  1. Even Cooking: Make sure to cut the steak and potatoes into similar-sized pieces for even cooking.
  2. Seal Tightly: Ensure the foil packets are sealed well to trap steam and keep the juices inside, which will result in tender steak and potatoes.
  3. Rest Time: Allow the packets to rest for a couple of minutes after cooking before opening to let the flavors meld together.


Can I use a different cut of steak?

Yes, you can use other tender cuts of steak like ribeye or New York strip. Just make sure to cut them into bite-sized pieces for even cooking.

Can I prepare the foil packets in advance?

Absolutely! You can assemble the foil packets a few hours ahead and store them in the refrigerator. Just bring them to room temperature before cooking.

What if I don’t have fresh garlic?

You can substitute fresh garlic with 1 teaspoon of garlic powder if needed. However, fresh garlic will provide the best flavor.

Can I cook these foil packets in the oven?

Yes, if you prefer or if the weather doesn’t permit grilling, you can bake the foil packets in the oven at 425°F (220°C) for 30-35 minutes.

How do I store leftovers?

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through.
