Ingredients
You’ll need:
- 2 lbs lean sirloin steak, trimmed and cut into 2-inch chunks
- 1 lb baby yellow potatoes, halved or quartered
- 1 Tbsp minced garlic (more if you love garlic!)
- 2 tsp Italian seasoning (or a mix of oregano, thyme & parsley)
- 1 tsp onion powder
- 3 Tbsp olive oil
- Salt & freshly ground black pepper, to taste
- Fresh parsley, chopped (for garnish, optional)
(Optional: 1 Tbsp melted butter or a squeeze of lemon for finishing)
Instructions
1️⃣ Prep the Ingredients
Preheat your grill to medium-high heat (around 425°F) or your oven to 400°F (200°C).
Wash and halve your baby potatoes, then cut the steak into even 2-inch cubes so everything cooks evenly.
2️⃣ Season Everything
In a large bowl, toss the steak and potatoes with olive oil, garlic, Italian seasoning, onion powder, salt, and pepper until well-coated.
3️⃣ Assemble the Foil Packets
Tear 4 large sheets of heavy-duty aluminum foil (about 12x18 inches).
Divide the steak and potato mixture evenly between them. Fold up the sides and seal tightly to create packets.
4️⃣ Cook to Perfection
- Grill: Place packets seam-side up and cook 8–10 minutes per side, until steak is browned and potatoes are tender.
- Oven: Place on a baking sheet and bake 20–25 minutes, flipping once halfway through.
5️⃣ Serve & Garnish
Carefully open each packet (watch for steam!). Sprinkle with fresh parsley, drizzle with melted butter or lemon juice, and serve immediately.
Tips for Success
🌿 Use sirloin or ribeye for the most tender, juicy steak bites.
🥔 Parboil potatoes for 5 minutes before baking if they’re extra large — they’ll finish evenly with the steak.
🔥 Don’t overcrowd the foil — air circulation helps everything brown beautifully.
🧄 Add a pat of garlic butter inside each packet before sealing for extra richness.
