How to Make Grilled Steak and Potato Foil Packs Recipe
Step 1: Prepare Your Cooking Environment
Start by heating your grill to medium-high or preheating your oven to 425 degrees Fahrenheit (220 degrees Celsius). This ensures your steak and potatoes cook evenly and develop those irresistible roasted flavors.
Step 2: Combine Steak and Potatoes
In a generously sized bowl, toss together the sirloin steak pieces and quartered baby potatoes. This is where your future meal starts coming to life as these ingredients mingle.
Step 3: Season Everything Thoroughly
Add the olive oil, minced garlic, onion powder, paprika, salt, and pepper to the bowl. Toss everything together carefully until each chunk of steak and potato is evenly coated. This seasoning blend is the heart of your foil packs, delivering bold flavor in every bite.
Step 4: Assemble the Foil Packs
Divide your steak and potatoes equally among the four foil sheets. Fold the foil tightly around the ingredients to create sealed packets that trap heat and steam, helping to tenderize the steak and soften the potatoes beautifully.
Step 5: Cook to Perfection
Place the foil packs directly on your grill grates and cook for about 10 to 12 minutes per side. Using an oven? Bake the foil packets for 20 to 25 minutes. Keep an eye out for tender potatoes and steak cooked just the way you like it.
Step 6: Finish and Garnish
Carefully open your foil packets — steam will escape quickly, so go slow! Sprinkle chopped fresh parsley over the top for a burst of color and a fresh, herbaceous note that complements the rich flavors inside.
How to Serve Grilled Steak and Potato Foil Packs Recipe

Garnishes
Aside from fresh parsley, feel free to add a squeeze of lemon juice or a dollop of sour cream to brighten the dish. A sprinkle of shredded cheese or some chopped green onions also works wonders to elevate each bite.
Side Dishes
These foil packs are a meal on their own but pairing them with a crisp garden salad, grilled seasonal vegetables, or a refreshing cucumber yogurt sauce makes dinner feel even more special and balanced.
Creative Ways to Present
Serve the foil packs directly on individual plates for a rustic vibe or carefully unwrap them tableside to release mouthwatering aromas and add a fun, interactive element to your meal. For gatherings, you can set a buffet-style station where everyone assembles their own foil pack before cooking.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers, store them in airtight containers in the refrigerator. They’ll keep well for up to three days, making them perfect for quick lunches or reheated dinners during a busy week.
Freezing
You can freeze uncooked foil packs for up to one month. Just prepare and seal the packs tightly, then place them in a freezer-safe bag. Thaw overnight in the refrigerator before grilling or baking.
Reheating
Reheat leftovers by wrapping them in foil and warming on a grill or in the oven at 350 degrees Fahrenheit until heated through, about 10-15 minutes. This helps maintain moisture and flavor without drying out the steak or potatoes.
FAQs
Can I use other types of steak for this recipe?
Absolutely! While sirloin is great for its balance of tenderness and flavor, cuts like ribeye or strip steak work well too. Just keep pieces roughly the same size to ensure even cooking.
What if I don’t have a grill? Can I cook this entirely in the oven?
Yes! The foil packs adapt perfectly to oven cooking. Bake them at 425 degrees Fahrenheit for about 20-25 minutes, turning once midway if you want even cooking, just like on the grill.
Are there any tips for making sure the potatoes cook through?
Use baby potatoes or quarter larger ones to speed up cooking. Also, cutting them into similar sizes and coating well with oil helps them become tender without burning.
Can I add vegetables to the foil packs?
Definitely! Bell peppers, onions, mushrooms, or zucchini make great additions. Just chop them into bite-sized pieces so everything cooks evenly.
How can I tell when the steak is done?
Cooking times may vary based on your grill heat and steak thickness. For medium-rare, aim for about 10-12 minutes per side on the grill. Using a meat thermometer and checking for 135°F internal temperature can guarantee perfect doneness.

Ingredients
Steak and Potatoes

- 3 tablespoons olive oil
- 4 cloves garlic, minced
- 1 teaspoon onion powder
- 1 teaspoon paprika
- Salt and pepper, to taste
- Fresh parsley, chopped (for garnish)
- 4 large sheets of aluminum foil
Instructions
- Preheat the Grill or Oven. Preheat your grill to medium-high heat or your oven to 425°F (220°C) to ensure it is hot enough for cooking the foil packs evenly.
- Combine Steak and Potatoes. In a large bowl, place the sirloin steak pieces and quartered baby potatoes, preparing them for seasoning.
- Add Seasonings. Drizzle the olive oil over the steak and potatoes. Add minced garlic, onion powder, paprika, salt, and pepper. Toss all ingredients thoroughly to coat everything evenly with the seasoning mixture.
- Prepare Foil Packs. Divide the seasoned steak and potatoes evenly onto the four large sheets of aluminum foil. Fold and seal the foil tightly around the contents to form sealed packets, which will help steam and cook the food while trapping flavors.
