Ingredients

For the Steak & Potatoes:

1.5 lbs top sirloin steak, cut into 1-inch cubes (or ribeye for extra flavor)
1 lb baby Yukon Gold potatoes, halved (no peeling needed!)
1 medium yellow onion, thinly sliced
1 tbsp minced garlic (or 2 tbsp if you love garlic!)
1 tbsp olive oil
2 tbsp unsalted butter, cubed
1 tbsp Italian seasoning
1 tsp kosher salt
½ tsp black pepper
2 tbsp fresh parsley, chopped (for garnish)

Optional Add-Ins:

Crispy bacon bits (because bacon makes everything better!)
Shredded cheddar cheese (melted over the top = heaven)
Asparagus or green beans (for an extra veggie boost)

How to Make Garlic Butter Steak & Potato Foil Packets

1. Par-Boil the Potatoes (Don’t Skip This!)

Bring a large pot of salted water to a boil.
Add the potatoes and cook for 5 minutes. They should be slightly tender but still firm.
Drain immediately and let cool—don’t rinse (the starch helps with crispiness).

2. Toss Everything Together

In a large mixing bowl, combine the steak, potatoes, onion, garlic, olive oil, Italian seasoning, salt, and pepper.
Toss well to coat everything evenly.

3. Assemble the Foil Packets

Tear 4 large sheets of heavy-duty aluminum foil (about 12×12 inches).
Divide the steak and potato mixture evenly between the foil sheets.
Top each portion with butter cubes for that rich, garlicky goodness.

4. Seal the Packets

Fold the foil over the ingredients, crimping the edges tightly to form a sealed packet.
Double-fold the edges to lock in steam—think of it like wrapping a burrito!

Cooking Methods

🔥 Grill / Campfire:

Preheat grill to 400°F (medium-high heat).
Place packets directly on the grates and cook for 8 minutes per side (16 minutes total).
Campfire Tip: Nestle packets in hot coals (not flames) for 15-20 minutes.

🔥 Oven:

Preheat to 425°F. Place packets on a baking sheet.
Bake for 20 minutes. For a charred finish, open packets and broil for 1-2 minutes.

Pro Tips for the Best Foil Packets

✔️ Par-Boil the Potatoes – This ensures they cook evenly with the steak.
✔️ Use Heavy-Duty Foil – Prevents leaks, especially over an open flame.
✔️ Let Packets Rest – After cooking, let them sit 2-3 minutes before opening (to avoid steam burns!).
✔️ Check the Steak Temp – Use a meat thermometer; steak should hit 145°F for medium.

FAQs

💬 Can I prep these ahead?
Yes! Assemble packets and refrigerate up to 6 hours before cooking—great for meal prep or camping trips.

💬 My potatoes are still hard. What now?
Remove the steak, reseal the packet, and cook the potatoes longer until tender.

💬 Can I use frozen steak?
Thaw it first! Frozen steak releases excess moisture, making the packets soggy.

Serving Ideas

🥖 Garlic Bread – Because more garlic is always a good idea.
