Optional Add-Ins

You can easily customize these packets with:

  • Sliced mushrooms
  • Bell peppers
  • Zucchini
  • Cherry tomatoes
  • Green beans
  • Shredded Parmesan
  • Crushed red pepper flakes
  • Worcestershire sauce
  • Fresh rosemary or thyme

What Kind of Steak Should You Use?

For foil packs, I like a tender steak that can be cut into bite-sized pieces.

Sirloin is a great choice because it's flavorful, widely available, and works well for this type of recipe.

You could also use:

  • Ribeye
  • New York strip
  • Tenderloin
  • Top sirloin

I wouldn't spend a fortune on an expensive steak here.

Once it's cut into pieces and cooked with garlic butter, potatoes, and seasonings, a good sirloin can make a fantastic dinner.

What Kind of Potatoes Work Best?

Small potatoes are especially convenient because they cook relatively quickly.

Baby Yukon Gold potatoes are one of my favorites because they have a creamy interior and buttery flavor.

Red potatoes also work beautifully.

If you're using larger potatoes, cut them into smaller pieces so they have enough time to become tender.

The important thing is to keep the potato pieces relatively similar in size.

That way, you don't end up with some pieces perfectly cooked while others are still rock hard.

Tools You'll Need

You don't need much equipment for this recipe.

  • Large mixing bowl
  • Sharp knife
  • Cutting board
  • Measuring spoons
  • Heavy-duty aluminum foil
  • Baking sheet
  • Tongs or a spatula

A baking sheet is important because it gives the foil packets a sturdy surface and catches any accidental leaks.

How to Make Steak and Potato Foil Packs

Step 1: Preheat the Oven

Preheat your oven to 425°F (220°C).

This higher temperature helps the potatoes roast nicely while the steak cooks.

Step 2: Prepare the Potatoes

Wash the potatoes well and cut them into halves or bite-sized pieces.

If you're using larger potatoes, cut them into roughly 1-inch chunks.

Try to keep the pieces similar in size.

Step 3: Prepare the Steak

Trim away any large pieces of excess fat and cut the steak into approximately 1-inch cubes.

Don't make the pieces too tiny.

Small pieces can cook very quickly and become dry before the potatoes are tender.

Step 4: Make the Garlic Butter

In a small bowl, combine:

  • Melted butter
  • Minced garlic
  • Italian seasoning
  • Smoked paprika
  • Salt
  • Black pepper
  • Olive oil

Give everything a good stir.

Already smells amazing, doesn't it?

Step 5: Season the Steak and Potatoes

Place the steak, potatoes, and onion in a large bowl.

Pour the garlic-butter mixture over everything and toss until the ingredients are evenly coated.

This is where you want to make sure every potato gets a little of that seasoned butter.

Step 6: Prepare the Foil

Tear off four large sheets of heavy-duty aluminum foil.

For easier handling, you can double-layer the foil.

Divide the steak and potato mixture evenly among the foil sheets, placing everything in the center.

Step 7: Fold the Packets

Bring the long sides of the foil together over the food.

Fold and seal them securely.

Then fold the shorter ends inward.

You want the packets sealed enough to hold in the butter and steam, but leave a little room inside for the hot air to circulate.

Step 8: Place on a Baking Sheet

Transfer the packets to a baking sheet.

Carefully place them seam-side up.

Step 9: Bake

Bake for approximately 30–40 minutes, depending on the size of your potato pieces and steak chunks.

The potatoes should be tender when pierced with a fork.

The steak should reach a safe internal temperature appropriate for your preferred doneness and the cut being used. For whole cuts of beef, the USDA minimum safe temperature is 145°F (63°C) followed by a three-minute rest.

If you prefer your steak more well done, you can cook it longer.

Step 10: Open Carefully

This part is important.

When you open the foil packets, hot steam will escape.

Open them carefully and keep your hands and face away from the initial burst of steam.

Sprinkle the finished packets with fresh parsley.

And then prepare yourself for the smell.

Seriously.

Should You Parboil the Potatoes First?

You don't have to, but it's an option.

If you're worried about the potatoes taking longer than the steak, you can partially cook them before assembling the packets.

Boil the potato pieces for about 5–7 minutes, then drain them well.

This gives them a head start and can shorten the oven time.

I usually skip this step because one of the reasons I love foil packs is keeping things simple!

How to Make Steak and Potato Foil Packs on the Grill

These are fantastic on the grill, too.

Preheat your grill to medium-high heat.

Place the sealed foil packets directly on the grill grates and cook for approximately 20–30 minutes, turning the packets carefully about halfway through.

Cooking time will vary depending on your grill, the size of the steak pieces, and the potatoes.

Always check the steak and potatoes before serving.

Can You Make These Over a Campfire?

Absolutely.

That's one of the reasons foil packet dinners are such a camping favorite.

For campfire cooking, use heavy-duty foil and consider doubling the layers.

Place the packets over hot coals rather than directly into large flames.

Rotate them carefully during cooking so the food cooks evenly.

Because campfire heat can vary dramatically, check the potatoes for tenderness and the steak for doneness rather than relying only on the clock.

Easy Variations

Cheesy Steak and Potato Foil Packs

Add shredded cheddar or Monterey Jack during the final few minutes of cooking.

The cheese melts into all those buttery steak juices.

It's ridiculously good.

Garlic Parmesan Steak and Potatoes

Add extra minced garlic and sprinkle Parmesan over the finished packets.

A little fresh parsley on top makes them look restaurant-worthy.

Steak and Mushroom Foil Packs

Add sliced mushrooms before sealing the packets.

The mushrooms become tender and soak up the garlic butter.

Spicy Steak Foil Packs

Add:

  • Red pepper flakes
  • Cajun seasoning
  • A pinch of cayenne

You can also drizzle the finished packets with your favorite hot sauce.

Steak, Potato, and Vegetable Foil Packs

Add chopped bell peppers, zucchini, green beans, or broccoli.

Just be mindful of how quickly each vegetable cooks.

Cut denser vegetables smaller so everything finishes at roughly the same time.

What to Serve With Steak and Potato Foil Packs

Honestly, these are pretty filling on their own.

But if you're serving them for a larger dinner, here are a few easy sides:

  • Green salad
  • Garlic bread
  • Steamed green beans
  • Roasted asparagus
  • Corn on the cob
  • Dinner rolls
  • Coleslaw
  • Grilled vegetables

And don't forget a little sauce!

A spoonful of garlic butter, steak sauce, or creamy horseradish sauce can be delicious with the finished steak.

My Best Tips for Perfect Foil Packs

Cut Everything Similar in Size

This might be the most important tip.

If one potato is the size of a golf ball and another is a tiny cube, they're not going to finish at the same time.

Keep your pieces relatively uniform.

Don't Overcrowd the Packets

Give the ingredients a little breathing room.

Overpacking can make the food steam rather than roast, and it can increase cooking time.

Use Heavy-Duty Foil

Regular foil can tear more easily, especially when you're moving a hot packet.

Heavy-duty foil or a double layer is much easier to work with.

Don't Open the Packets Constantly

Every time you open the foil, you're letting heat and steam escape.

Try to leave them closed until you're ready to check for doneness.

Rest the Steak

Once the packets are opened, let the steak rest for a few minutes before serving.

This gives you a chance to garnish everything and lets the juices settle.

Check Doneness With a Thermometer

A thermometer is much more reliable than guessing from cooking time alone.

Steak size, potato size, oven temperature, and the type of beef can all affect how quickly the food cooks.

Can I Make Steak and Potato Foil Packs Ahead of Time?

Yes!

You can assemble the packets several hours ahead and refrigerate them until you're ready to cook.

Keep the uncooked packets refrigerated and don't leave raw steak sitting at room temperature while you wait.

When you're ready to cook, place the packets on a baking sheet and proceed with the recipe.

If the packets are very cold from the refrigerator, they may need additional cooking time.

How to Store Leftovers

Allow leftovers to cool promptly and transfer them to airtight containers.

Refrigerate within 2 hours and use within about 3–4 days.

For reheating, a skillet or oven can help bring back some of the roasted texture.

The microwave works, too, although the potatoes may become softer.

If you're reheating steak, avoid overcooking it because it can become chewy.

Can You Freeze Steak and Potato Foil Packs?

You can freeze cooked steak and potatoes, although the potatoes may change texture after freezing and thawing.

For the best quality, cool the food promptly, transfer it to airtight freezer-safe packaging, and label it with the date.

Thaw in the refrigerator before reheating.

Frequently Asked Questions

What steak is best for steak and potato foil packs?

Sirloin is an excellent choice because it's flavorful and works well when cut into bite-sized pieces. Ribeye, New York strip, and other tender beef cuts can also work.
