Ingredients You’ll Need

It’s almost hard to believe how a simple list of ingredients can come together and deliver such bold, satisfying flavors! Each item in this lineup plays an important role in making your Garlic Butter Steak and Potato Foil Packets a guaranteed hit, from juicy steak to aromatic herbs.

Steak (1 ½ pounds, sirloin recommended): Sirloin is tender and quick-cooking, but you can use your favorite cut for this recipe.
Baby potatoes (1 pound, cut into ½-inch pieces): These add a buttery, creamy texture and cook perfectly alongside the steak.
Onion (1, peeled, halved, and thinly sliced): Sweet onion slices melt into the packet, enhancing all the flavors.
Olive oil (1 tablespoon): Just a touch helps everything caramelize beautifully and keeps the steak juicy.
Fresh parsley (2 tablespoons, chopped): Parsley brightens things up and adds a fresh pop.
Minced garlic (1 tablespoon or more): Garlic brings all the classic aroma and punch—feel free to go heavy-handed!
Italian seasoning (1 tablespoon): This blend of herbs adds depth and ties all the flavors together.
Salt and pepper (to taste): Essential for bringing out the best in both steak and potatoes.
Butter (2 tablespoons, cubed): Butter melts into the entire packet, bathing everything in richness.

How to Make Garlic Butter Steak and Potato Foil Packets

Step 1: Par-boil the Potatoes

Start with the potatoes—a little pre-cooking goes a long way! Par-boiling helps guarantee that your potatoes turn out soft and fluffy inside, even as they crisp up around the edges in the oven or on the grill.

Step 2: Cool Before Handling

After draining your par-boiled potatoes, give them a few minutes to cool. You want them to be cool enough so you can toss them easily without burning your fingers!

Step 3: Prep and Cut the Steak

Slice your steak into sturdy chunks—think about 2.5–3 inches for well done, a little bigger (3–4 inches) for medium, or go even larger for medium rare. This step lets you control your preferred doneness and ensures everything cooks evenly in your Garlic Butter Steak and Potato Foil Packets.

Step 4: Combine Everything in a Bowl

In a large bowl, toss the steak, cooled potatoes, onion, olive oil, parsley, garlic, Italian seasoning, and a good pinch of salt and pepper. This is your moment to make sure every bite gets plenty of flavor!

Step 5: Assemble the Foil Packets

Spread out four large pieces of aluminum foil (about 12×12 inches each). Divide the steak and potato mixture evenly among them, piling it right in the center. Drop cubes of butter over each pile—these will melt into gorgeous, garlicky pools.

Step 6: Seal the Packets

Fold up each foil square around the steak and potatoes, crimping the edges tightly to make sure nothing leaks. The tight seal is what traps all those irresistible flavors inside!

Step 7: Cook – Grill or Oven Method

Time to cook your Garlic Butter Steak and Potato Foil Packets! On a hot grill (or even over campfire coals), cook for 8–10 minutes on each side until the potatoes are fork-tender and the steak is cooked to your liking. For oven baking, set the temperature to 425°F and bake for about 20 minutes. If you love a little caramelized char, unwrap the packets and broil for a minute or two at the end.

How to Serve Garlic Butter Steak and Potato Foil Packets

Garnishes

Right before serving, open each foil packet carefully so the steam escapes away from you. Sprinkle with extra chopped fresh parsley, a pinch of coarse salt, and maybe even a little freshly grated Parmesan for the ultimate finishing touch.

Side Dishes

These packets are a meal in themselves, but you can pair Garlic Butter Steak and Potato Foil Packets with a crisp green salad or some crusty bread to soak up any pooled garlic butter. If you want something veggie-focused, steamed green beans or roasted asparagus complement this dish beautifully.

Creative Ways to Present

For casual gatherings, bring the sealed foil packets straight to the table—everyone loves unwrapping their own! For a more polished dinner, slide the contents onto plates and drizzle with the buttery juices. You can even serve straight from the grill at a backyard picnic for that irresistible smoky aroma.

Make Ahead and Storage

Storing Leftovers

Let the Garlic Butter Steak and Potato Foil Packets cool completely, then transfer the contents to an airtight container. Refrigerate for up to three days. The flavors really meld together, so leftovers taste just as dreamy the next day!

Freezing

If you want to get ahead on meal prep, assemble the raw packets and freeze them before cooking. When ready to enjoy, thaw overnight in the fridge, then cook as usual. Avoid freezing cooked potatoes, as the texture can change.

Reheating

For best results, reheat leftovers gently in a covered skillet over medium-low heat, adding a splash of water or broth to keep things moist. You can also reheat in the oven—wrap in foil and bake at 350°F until warmed through.

FAQs

Can I use a different cut of steak?

Absolutely! Sirloin is my favorite for Garlic Butter Steak and Potato Foil Packets because it’s tender and not overly fatty, but ribeye, strip, or even filet also work well—just adjust cooking time as needed.

Do I have to par-boil the potatoes?

While you technically can skip this step, par-boiling ensures perfectly tender potatoes—otherwise, they may end up undercooked while the steak finishes quickly.

Can I make these foil packets in advance?

You sure can! Assemble your packets (leave out the butter until just before cooking), seal, and refrigerate for up to 24 hours until you’re ready to grill or bake.

Are Garlic Butter Steak and Potato Foil Packets gluten-free?

Yes, as long as you double-check that your seasonings and butter are gluten-free, this recipe is naturally gluten-free—delicious and inclusive!

What’s the best way to keep the packets from leaking?

Use heavy-duty aluminum foil and make sure to crimp the edges tightly. Double-wrapping with a second layer of foil also works wonders, especially if you’re cooking over an open fire.

Final Thoughts

If you’re looking for a fun, easy dinner that guarantees big smiles and even bigger flavors, you just can’t go wrong with Garlic Butter Steak and Potato Foil Packets. They’re a breeze to assemble and a joy to eat—so go ahead and treat yourself to this savory, no-fuss favorite!
