Step-by-Step Instructions
(Simple—but don’t skip the foil seal!)
1. Prep & Preheat
Heat your oven to 400°F (200°C).
Line a rimmed baking sheet with foil for easy cleanup.
Tear off 4 large sheets of heavy-duty foil (about 12×18 inches). Lightly spray the center of each with nonstick spray (optional but helpful for release).
2. Divide & Layer
Evenly divide ingredients among the 4 foil sheets:
→ ¼ of the potatoes
→ ¼ of the onions
→ ¼ of the beef slices
Drizzle each portion with ¾ tbsp olive oil and sprinkle with ½ tsp steak seasoning. Add a pinch of salt/pepper if needed.
3. Wrap Tightly
Bring up the long sides of the foil and fold together tightly to seal.
Fold the short ends inward to create fully enclosed, leak-proof packets.
Key: A tight seal traps steam—the secret to tender beef and perfectly cooked potatoes.
4. Bake Until Tender
Place packets on the baking sheet.
Bake for 35–40 minutes, until potatoes are fork-tender and beef is cooked through.
Don’t peek! Steam is essential—open only when ready to serve.
5. Rest & Serve
Let packets rest for 5 minutes (they’ll be molten hot!).
Carefully open—watch for rising steam—and serve directly from the foil for rustic charm.

Frequently Asked Questions
Can I use chicken or pork?
Yes! Substitute with thinly sliced chicken breast or pork tenderloin—adjust cook time as needed.
Do I need heavy-duty foil?
Highly recommended. Regular foil may tear, causing leaks and dry spots.
Can I prep ahead?
Assemble packets (unbaked), refrigerate for up to 24 hours. Add 5 minutes to bake time.
Why not stir during baking?
The sealed environment creates a mini steam oven—no stirring needed!
