How Long to Cook Whole Pork Tenderloin (1–1.25 lb) in the grill
Specification: 1–1.25 lb tenderloin, silverskin trimmed off, dry-brined 1 hour with kosher salt
3-Step Execution Protocol
Preheat grill to Two-zone: 500°F direct sear + 400°F indirect finish. Clean and oil grates. Prepare whole pork tenderloin (1–1.25 lb) (1–1.25 lb tenderloin, silverskin trimmed off, dry-brined 1 hour with kosher salt).
Cook for 18–22 mins (sear all four sides, then indirect to temp). Flip at the 4-minute mark for even browning.
A whisper of pink at the exact centre when sliced; juice runs clear-pink, not red. Confirm internal temperature reaches 142°F pull → 145°F after a 5-minute rest (USDA safe minimum for whole pork with the 3-minute rest rule). Rest for 5 minutes before serving.
USDA FSIS 145°F safe minimum for whole pork cuts with a 3-minute rest (revised 2011 guidance); two-zone tenderloin method as published in the Weber Grill Guide and Cook's Illustrated.
