Ingredients You’ll Need
This recipe keeps things simple but packed with flavor. You probably already have most of these ingredients sitting in your kitchen right now.
Steak
- 1½ pounds sirloin steak, cut into bite-sized pieces
Sirloin is my favorite cut for foil packets because it stays tender while cooking fast. Plus, it gives you that steakhouse flavor without spending ribeye money. Win-win.
Potatoes
- 1 pound baby potatoes, cut into ½-inch pieces
Baby potatoes cook evenly and get wonderfully soft inside the packets. I usually halve or quarter them depending on size.
Onion
- 1 onion, peeled, halved, and thinly sliced
The onions melt into the garlic butter while cooking. Seriously, don’t skip them.
Olive Oil
- 1 tablespoon olive oil
This helps coat the potatoes and steak while adding a little richness.
Fresh Parsley
- 2 tablespoons chopped fresh parsley
Fresh parsley adds color and freshness that balances the butter beautifully.
Garlic
- 1 tablespoon minced garlic
You can absolutely add more garlic if you’re a garlic lover. I usually do because, well… garlic makes everything better.
Italian Seasoning
- 1 tablespoon Italian seasoning
This gives the packets that cozy herb flavor that tastes amazing with steak and potatoes.
Salt and Pepper
- Salt and pepper to taste
Don’t be shy here. Potatoes need seasoning.
Butter
- 2 tablespoons butter, cubed
This is where the magic happens. The butter melts into everything and creates the most delicious sauce right inside the foil.
How to Make Garlic Butter Steak and Potato Foil Packets
One of the best things about this recipe is how easy it is. No fancy cooking skills needed.
Step 1: Preheat Your Oven or Grill
- Oven: 425°F
- Grill: Medium-high heat
High heat helps the potatoes cook faster while giving the steak great texture.
Step 2: Prepare the Steak and Potatoes
In a large bowl, combine:
- Steak pieces
- Potatoes
- Sliced onions
- Olive oil
- Garlic
- Italian seasoning
- Salt
- Pepper
- Parsley
Mix everything together until evenly coated.
Honestly, this is the point where it already smells amazing.
Step 3: Assemble the Foil Packets
Lay out large sheets of heavy-duty foil.
Divide the steak and potato mixture evenly among the foil sheets. Top each packet with cubes of butter.
Fold the foil tightly around the ingredients so the steam stays trapped inside.
Quick tip — double-wrap the packets if you’re grilling. It helps avoid leaks and burned edges.
Step 4: Cook the Packets
Oven Method
Place the foil packets on a baking sheet and bake for about 25 to 30 minutes.
Grill Method
Place packets directly on the grill and cook for 20 to 25 minutes, flipping once halfway through.
Cooking times can vary a little depending on how large your potato pieces are. Smaller cuts cook faster.
Step 5: Carefully Open and Serve
Be careful opening the packets because the steam gets HOT. Like, “ouch, why did I put my face there?” hot.
Sprinkle extra parsley on top if you want that restaurant-style look.
Serve immediately while everything is buttery and sizzling.
What Makes This Recipe So Good
There’s something about garlic butter mixed with steak juices that turns simple ingredients into a restaurant-quality dinner.
The potatoes absorb all those savory flavors while the onions become soft and sweet. Meanwhile, the steak stays juicy because the foil locks in moisture.
Honestly, every bite tastes cozy and satisfying.
Best Steak Cuts for Foil Packets
Sirloin works beautifully here, but you’ve got options.
Great Steak Choices
- Sirloin
- Ribeye
- New York strip

I usually avoid super lean cuts because they can dry out faster in foil packets.
Tips for Tender Steak Every Time
A few small tricks make a huge difference.
Cut Steak Evenly
Uniform pieces cook evenly and prevent chewy bites.
Don’t Overcook
Steak keeps cooking slightly after removing from heat.
Use Heavy-Duty Foil
Thin foil tears easily and can leak those buttery juices everywhere.
Cut Potatoes Small
This helps them cook fully before the steak gets overdone.
Delicious Add-Ins
Honestly, foil packet dinners are super flexible.
You can toss in:
- Mushrooms
- Bell peppers
- Zucchini
- Corn
- Red pepper flakes
- Shredded parmesan cheese
My cousin added bacon once and everybody lost their minds over it.
Can You Make These Ahead of Time?
Absolutely.
You can assemble the foil packets up to 24 hours ahead and keep them refrigerated until ready to cook.
That makes this recipe fantastic for:
- Busy weeknights
- Camping trips
- Tailgating
- Backyard cookouts
- Meal prep
How to Store Leftovers
If you somehow end up with leftovers — which honestly rarely happens in my house — here’s how to store them.
Refrigerator
Store in an airtight container for up to 3 days.
Reheating
Reheat in the oven at 350°F or warm gently in a skillet.
Microwaving works too, but the potatoes stay crispier in the oven.
