What can I say? When it comes to foil packet dinners, I’m a fan. Just in time for grilling season, my garlicky skillet steak bites and potatoes inspired this foil packet version. These garlic steak and potatoes foil packets are an easy dinner to make on the grill, over a campfire, or even in the oven on a rainy day. It’s a flavorful, hearty meal with juicy hunks of sirloin steak and tender seasoned potatoes, cooked all at once, ready to pair with your favorite summer sides.

Why I Love This Steak and Potatoes Foil Pack Recipe

  • Quick. Cooking your meat and potatoes together in foil is fast and easy. Have dinner ready in a flash with next to no cleanup (my favorite part!).
  • Flavor-packed. The garlic and herb marinade in this recipe is next-level delicious and brings out the savory flavors of the steak. 
  • Customizable. There are endless ways to turn your steak bites and potatoes into a well-balanced meal. Change up the marinade, add some veggies, or serve your foil packs with your favorite sides. See later on for ideas.
  • Cook anywhere. Make your steak and potato foil packets ahead and take them to go. You can cook them over a grill in the Great Outdoors, or in the oven. This “hobo dinner” is convenient and packed with flavor!

Ingredients You’ll Need

You don’t need a ton of ingredients to make these tasty steak and potato foil packs. Just a few essential fridge and pantry items that I outline below.

  • Steak: I tested this steak and potato foil pack recipe with flank steak, ribeye, and top sirloin. While this recipe worked with all of them, top sirloin is my first choice for foil packets. It’s lean, flavorful, and stays tender when cooked using this method. 
  • Potatoes: Baby Yukon gold potatoes are my favorite because you don’t need to peel them. Another waxy potato, like red potatoes or fingerling potatoes, will also work.
  • Garlic and Herbs: We season the meat and potatoes with freshly minced garlic and a combination of dried thyme, rosemary, salt, and pepper. Feel free to substitute fresh versions of the herbs instead.

How to Grill Steak and Potatoes In Foil

Before we take these foils to the grill, you’ll need to chop up the steak and potatoes and get those babies marinating. Here’s how easily these foil packets come together:

  • Marinate the steak and potatoes. Combine the steak bites and chopped potatoes in a bowl with the garlic, herbs, and a couple of generous glugs of olive oil. If time allows, let the meat and potatoes marinate in the fridge for 30 minutes. Remember to take the steak and taters out about 15 minutes before you grill them, to take the chill off.
  • Assemble the foil packets. Cut four large sheets of foil from your roll. Add the marinated steak and potatoes to the center of each foil sheet. To make your foil packs, bring two sides together, wrap the foil up tightly, and finally roll up the ends to seal.
  • Grill. Grill the foil packets on high for 10 minutes per side. Remember to flip! Once your potatoes and steak are tender, you’re ready to serve. See below for some of my favorite serving suggestions.

Oven Method

This outdoorsy dinner is easy to take indoors if the weather is uncooperative or if you don’t feel like grilling. To make this recipe in the oven instead, bake your foil packets at 450ºF for 15-20 minutes. I include detailed instructions in the recipe card.

Should I Parboil the Potatoes?

Potatoes take longer to cook than steak. This leaves two options: the first is to cut your potatoes up small enough to cook through in the suggested cooking time. The second option is to precook or parboil your potatoes. If you’re not pressed for time, parboiling is the recommended option.

Parboiling is easy to do by boiling your whole potatoes in water for about 5 minutes, then draining them and cutting them up as directed. See the recipe card notes for details.

Recipe Tips

  • Rare or medium-rare. The larger the pieces, the rarer your meat will be. This way, the steak is also less likely to be cooked before the potatoes. If you prefer your steak well-done, cut it into 1-inch cubes.
  • Use sturdy foil. We’ve found that heavy-duty foil holds up best when cooking foil packet dinners on the grill or over an open fire. You can also use a double layer of regular foil if needed.
  • Browning. Once the steak and potatoes are cooked, open up the foil and place the packets under the broiler to char the steak a bit. Make sure that you don’t leave them unattended, as the tops can burn easily!
  • If your steak cooks before the potatoes are done, do not worry. This can sometimes happen depending on the type/size of potatoes or whether you parboil them or not. To fix this, carefully open the packets and transfer the steak to a plate to rest (you can cover the steak with a new sheet of foil to keep it warm). Close the foil packets and return the potatoes to the grill until they’re done.
  • Be careful when opening the foil packets. A lot of steam builds up inside the foil in the heat, which we love, because it keeps things juicy. But this also means there are a lot of hot liquids in there. For this reason, never open or eat a foil packet in your lap. Make sure it’s on a level surface.
  • Make ahead. Marinate the potatoes and steak bites in advance, or assemble the foil packs up to 6 hours before cooking. Keep the packets refrigerated or chilled in the cooler until you’re ready to cook.

Variation Ideas

  • Marinade. Change things up and borrow the soy and citrus marinade from my steak and potatoes skillet with vegetables.
  • Add-Ins. Crumbled bacon is an easy way to add flavor to steak and potatoes. Or, grate on some fresh cheddar, Pepper Jack, or parmesan cheese to melt inside the packets. 
  • Seasonings. You can season your foil packets however you’d like. Try Cajun spice or Jamaican jerk seasoning for a spicy kick, or another herb blend. Homemade fajita seasoning would also be delicious.
  • Vegetables. Choose veggies with similar cooking times to cook inside your steak and potatoes foil packets. Chopped bell peppers, onions, green beans, or broccoli are all great options.

Serving Suggestions

Savory steak and potato foil packets were made for summer dinners. They’re wonderful to prepare for backyard barbecues, camping, or just an easy weeknight meal. One of our go-to BBQ sides, creamy coleslaw is quick and easy. It’s great to make ahead for camping, too. You can’t go wrong with a refreshing broccoli apple salad or a tangy and crunchy tomato and cucumber salad. While the grill is hot, pair your steak and potatoes with grilled zucchini or grilled corn. Or, try these cheesy grilled asparagus foil packs.

Storing and Reheating Leftovers

  • Once cooled, discard the foil and store any leftover steak and potatoes in an airtight container. Leftovers can be kept in the fridge for up to 5 days, or in the freezer for up to 3 months. Thaw the steak and potatoes in the fridge before reheating.
  • The best way to reheat leftover steak and potatoes is in a covered skillet over medium-low heat until everything is warmed through.

Potatoes take longer to cook than steak. For that reason, I have a couple of suggestions:
  • Precook or parboil the potatoes. To parboil small potatoes, you’ll need to place the potatoes in a pot with cold water and bring to a boil. Turn down heat to a simmer and cook for about 5 minutes. Drain and let cool for a minute or two, then cut and continue with the recipe.
  • OR, don’t precook the potatoes, but cut them up to about 1-inch cubes. Also try using mini Yukon gold potatoes because they work best with the cooking time.
  • For a rare or medium-rare steak, I suggest cutting the steak into larger pieces because, as stated before, the potatoes need more time to cook. If you like a well done steak, cut the steak into 1-inch pieces.
