3-Step Execution Protocol

Preheat & Prep

Preheat oven to 400°F (204°C). Arrange pork tenderloin (whole, 1.25 lb) (1.25 lb whole pork tenderloin, trimmed of silver skin, tucked at the thin tail, placed diagonally on pan) on a parchment-lined sheet pan in a single layer. Spray lightly with high-smoke-point oil.

Cook & Flip

Cook for 20–25 mins. Flip at the 12-minute mark for even browning.

Check & Rest

Golden brown roasted exterior, firm to touch with slight give, reads 140°F at center pulling to 145°F. Confirm internal temperature reaches 140°F (pull) → 145°F (63°C) medium after 5-min rest. Rest for 5 minutes before serving.

Pro Tip: Tuck the narrow tail under and tie with butcher twine so the roast cooks uniformly from end to end without drying.
