How Long To Cook Pork Tenderloin?

How long do you cook pork tenderloin by method?

Timing depends on size and method. Standard pork tenderloin weighs 1-1.5 pounds. Oven baking at 400°F (205°C): 20-27 minutes; check at 20. Oven baking at 425°F: 18-22 minutes. Sear-then-oven method (best): pan-sear 6-8 min in cast iron; transfer to 400°F oven for 10-15 min. Grilling over medium-high heat: 12-15 minutes; turn every 3-4 minutes; do not close lid to prevent flare-up. Air frying at 400°F: 20-25 minutes; flip halfway. Roasting on vegetables: 25-30 min at 400°F. Slow cooker: 3-4 hours on low; produces different texture (falling apart tender). Instant Pot: 12-15 minutes high pressure + broil for crust. Sous vide: 1-2 hours at 140°F then hot sear. Stuffed pork tenderloin: add 5-10 minutes to any method; check stuffing temp. Frozen pork tenderloin (not recommended): thaw first for best results. The 145°F (63°C) internal temperature is per USDA (revised from 160°F in 2011). Old recipes calling for 160°F+ produce dry tenderloin.

How do you cook pork tenderloin properly?

Sear-then-oven method produces best results. Step 1: pat tenderloin completely dry (essential for good sear). Step 2: trim silverskin (the shiny white membrane) - it's tough and doesn't render. Step 3: season generously with salt, pepper, and any spices (garlic powder, paprika, herbs). Step 4: heat cast iron pan over medium-high with oil until shimmering. Step 5: sear tenderloin on all sides (top, bottom, sides) - about 6-8 minutes total for good crust. Step 6: transfer skillet to preheated 400°F oven; roast 10-15 minutes until internal temp reaches 140°F. Step 7: check temperature; remove at 140°F (carryover brings to 145). Step 8: rest 5-10 minutes tented with foil. Step 9: slice into medallions against the grain. For marinated tenderloin: marinate 1-4 hours; balsamic, teriyaki, honey-mustard all work well. Don't overcook - lean meat dries in minutes past 145°F. The sear step is essential for great crust.

How do you know when tenderloin is done?

Internal temperature is the gold standard. Use an instant-read thermometer in the thickest part; 145°F (63°C) is USDA food safety minimum with 3-min rest; can remove at 140°F as carryover finishes cooking. Visual cues: exterior deeply golden-brown; slight pink blush in center is acceptable and desirable at 145°F; deep pink means undercooked; gray-white throughout means overcooked. Texture: firm but slightly yielding when pressed; rock-hard means overcooked. Don't undercook below 140°F final. Don't overcook past 155°F - dry, tough tenderloin results; the difference between juicy and dry is 10°F. Modern pork guidance changed in 2011 - the 160°F rule from older cookbooks is outdated. A slight blush of pink is fine at 145°F. The sweet spot: 140-145°F internal with browned crust and slight pink center. After cooking: rest 5-10 minutes tented with foil; juices redistribute; slicing hot loses juices.

Tips for perfect pork tenderloin?

Several techniques produce restaurant-quality results. Trim the silverskin: essential; it's tough and doesn't render. Pat very dry: for great sear. Sear before roasting: builds flavor and crust. Cook to 145°F (not higher): trust the thermometer. Rest 5-10 minutes: essential for juicy medallions.
