Tip: you can find full list of ingredients and measurements in the recipe card below
Instructions
Preheat your oven to 425°F if baking, or preheat your grill to high heat.
In a large mixing bowl, combine the steak chunks, baby potatoes, garlic, olive oil, Italian seasoning, onion powder, salt, and pepper. Toss until everything is evenly coated.
Divide the steak and potato mixture among four 12×12-inch sheets of aluminum foil. Wrap each tightly to seal into a packet.
For grilling: Place packets on the hot grill for about 10 minutes per side.
For oven baking: Arrange packets on a baking sheet and bake for 20–25 minutes, or until steak and potatoes are cooked through.
Open foil carefully to avoid steam. Garnish with chopped parsley and serve hot.
Variations
Add chopped bell peppers, mushrooms, or onions for extra flavor and color
Swap the Italian seasoning for Cajun, taco seasoning, or smoked paprika
Top with shredded cheddar or mozzarella before sealing the packets for a melty finish
Use sweet potatoes or cauliflower florets instead of yellow potatoes for variety
Swap sirloin for chicken breast or tofu for a different protein option
Heating & Storage
Store leftovers in the foil packets or transfer to an airtight container. Keep refrigerated for up to 3 days. To reheat, place foil packets back in the oven at 350°F for about 10–15 minutes or heat in a skillet with a splash of water or broth. Foil packets can also be frozen for up to 3 months; thaw overnight before reheating.
Frequently Asked Questions
How long should I cook foil packets in the oven?
Bake for about 20 to 25 minutes at 425°F, depending on your desired steak doneness and potato size.
Can I use a different cut of steak?
Yes. Flank steak, ribeye, or strip steak all work well. Just make sure they’re cut into bite-sized chunks.
Do I need to pre-boil the potatoes?
No. Just cut them small (about 1 to 2 inches), and they’ll cook through in the foil.
Can I prepare the packets ahead of time?
Yes. Assemble and refrigerate them for up to 24 hours before cooking. Add 3 to 5 minutes to the total cooking time if starting from cold.
Are foil packets safe for grilling?
Yes. Use heavy-duty foil to prevent tears and leaks, especially when placing directly on high heat.
What can I serve with these steak foil packets?
A simple salad, garlic bread, or grilled corn works perfectly on the side.
Can I make this spicy?
Absolutely. Add red pepper flakes, cayenne, or your favorite hot sauce to the seasoning mix.
Is this recipe kid-friendly?
Very. You can easily tone down the seasonings and cut everything small for easy bites.
Can I cook these in the oven without foil?
You can bake everything in a covered casserole dish, but the sealed foil method locks in the most flavor and moisture.
Can I make this for a crowd?
Yes. Just scale up the recipe and prepare more packets. Great for parties or group grilling.
