How to Make Grilled Steak and Potato Foil Packs Recipe
Step 1: Preheat and Prepare the Ingredients
Start by heating your grill to medium-high temperature to get that perfect sear and even cooking. While that’s warming up, toss the cubed steak, potatoes, bell pepper, and red onion into a large mixing bowl. This forms the base of your foil packs.
Step 2: Mix the Marinade
In a smaller bowl, whisk together olive oil, Worcestershire sauce, minced garlic, thyme, rosemary, salt, and black pepper. This marinade is the secret sauce that transforms these simple ingredients into something incredibly flavorful, infusing the meat and vegetables with a beautiful herbal and savory character.
Step 3: Combine and Toss
Pour the marinade over the steak and vegetable mixture, then toss everything together gently but thoroughly. The goal is for every cube of steak and piece of veggie to be evenly coated, ensuring consistent, savory bites in every foil packet.
Step 4: Assemble the Foil Packs
Divide the mixture evenly onto four large sheets of heavy-duty aluminum foil. Neatly fold and seal the foil around the food, creating tight packets. This technique locks in steam and heat, helping the potatoes cook through and the steak stay juicy without drying out.
Step 5: Grill to Perfection
Place the foil packets on the grill and cook for 15 to 20 minutes, turning once halfway through. This turning step ensures even cooking and browning on all sides. You’ll know it’s ready when the potatoes are tender and the steak is cooked to your preferred doneness.
Step 6: Add Cheese and Garnish
Carefully open each foil pack and, if you’re going for extra indulgence, sprinkle shredded cheddar cheese over the hot steak and potatoes. Close the packs just enough to let the cheese melt beautifully within 1 to 2 minutes. Finish with a sprinkle of chopped fresh parsley for a fresh, colorful touch.
How to Serve Grilled Steak and Potato Foil Packs Recipe

Garnishes
Fresh parsley is a fantastic simple garnish that brings brightness and a touch of herbal freshness, but you can also experiment with a dollop of sour cream or a sprinkle of green onions to add layers of creamy and sharp flavors that complement the grilled meat and tender potatoes perfectly.
Side Dishes
Since the foil packs are already packed with hearty veggies and starch, light sides work best. Consider serving with a crisp garden salad or grilled asparagus for some green crunch. A tangy coleslaw is another excellent option that adds contrast to the smoky, savory packets.
Creative Ways to Present
If you’re hosting a casual cookout, serve the foil packs right on colorful plates with a simple side salad to keep things easy and convivial. For a more elegant setup, open the packs tableside to release that irresistible aroma, garnishing with fresh herbs and a drizzle of balsamic glaze to amp up sophistication.
Make Ahead and Storage
Storing Leftovers
Leftover grilled steak and potato foil packs keep incredibly well in an airtight container in the refrigerator for up to 3 days. The flavors meld beautifully overnight, often tasting even better the next day.
Freezing
To freeze, assemble the foil packs but skip grilling them first. Wrap tightly and place in the freezer for up to 2 months. When you’re ready to enjoy, simply grill or bake from frozen, adding a bit of extra time to ensure everything is heated through.
Reheating
Reheat leftover or thawed foil packs by wrapping them in foil and placing them on a grill or in a preheated oven at 350°F until warmed through. This helps retain the juicy texture and delicious flavors without drying anything out.
FAQs
Can I use other types of steak for this recipe?
Absolutely! While sirloin is great for its balance of tenderness and price, you can use ribeye or flank steak. Just remember to adjust the cooking time slightly depending on thickness and cut to avoid overcooking.
Is it possible to make this recipe vegetarian?
Yes! Simply swap the steak for hearty vegetables like portobello mushrooms, zucchini, or even plant-based meat substitutes. The potatoes and seasonings will still make the foil packs flavorful and satisfying.
How do I ensure the potatoes cook thoroughly?
Cut the baby potatoes into small, evenly-sized halves or quarters so they cook at the same rate as the steak. Wrapping tightly in foil helps steam them, but you can also parboil them briefly if you’re worried about cooking time.
Can I prepare the packs indoors without a grill?
Definitely. You can bake the foil packs in a preheated oven at 425°F for 20 to 25 minutes, which delivers tender steak and potatoes without the need for outdoor grilling.
What sides pair best with the Grilled Steak and Potato Foil Packs Recipe?
Since the foil packs are hearty, lighter sides like a fresh salad, steamed green beans, or grilled corn work beautifully. For a more indulgent meal, creamy coleslaw or crusty bread can complement the dish nicely.
