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.
