3-Step Execution Protocol

Preheat & Prep

Preheat oven to 400°F (204°C). Prepare pork tenderloin (whole roast) (1-1.25 lb whole pork tenderloin, trimmed of silver skin, seared in skillet first then oven-finished in baking dish). Spray lightly with high-smoke-point oil.

Cook & Flip

Cook for 18–22 mins. Flip at the 10-minute mark for even browning.

Check & Rest

Caramelized golden-brown exterior, firm with gentle spring, reads 140°F at thickest point carrying over 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.

Verification Basis & Testing Rig

USDA FSIS Safe Cooking of Whole Pork (145°F + 3 min rest); National Pork Board Oven Roasting Specs.

Pro Tip: Remove from the oven at 140°F; carryover cooking will raise the internal temperature to the USDA safe 145°F while preserving blush-pink juiciness.
