Pork tenderloin baked under a thick sauce of cream of mushroom soup, sour cream and dry onion soup mix. No searing: the sauce turns into a rich, savory gravy in the oven.
Cream of chicken soup works in place of cream of mushroom. Thinner tenderloins finish closer to 15 minutes uncovered; thicker ones need the full 25, so check with a meat thermometer.
