Pork Tenderloin
Sear all sides, then roast 425°F, 15-20 min to 145°F.
Cylindrical shape needs oven’s even radiant heat after searing. Stovetop alone can’t cook a cylinder evenly.
Step-by-Step
1. Trim silver skin (slippery membrane on surface).
2. Pat dry. Season all over.
3. Heat oven-safe pan over med-high.
4. Sear all sides — roll it with tongs (2 min per 'side', about 6-8 min total).
5. Transfer to 425°F oven.
6. Roast 15-20 min.
7. Pull at 140°F.
8. Rest 5-10 min. Slice into medallions.
Size & Portion Guide
Small tenderloin (3/4 lb): 12-15 min in oven after sear.
Standard (1-1.25 lb): 15-20 min.
Large (1.5 lb): 18-22 min.
Cut in half if too long for pan.
Medallions (pre-sliced 1 inch): stovetop only, 3-4 min/side.
Roast without sear (less flavorful but simpler).

Any oven-safe heavy pan. Or sear in whatever pan you have, then transfer to a sheet pan for the oven portion.
