OMG!!!! How does this not have more reviews?! It just doesn't get any easier or better than this! We used fresh rosemary, but other than that followed the recipe. I will probably never make a pork tenderloin any other way! I was nervous about not adding any liquid...but the other reviewers were right! None needed! There was so much juice when it was done! I made gravy by thickening the juices first with about 2 tsp cornstarch mixed into tablespoon of water. It was kind of salty and I wanted more gravy anyways to go with our mashed potatoes, so I added about 3/4 of a cup of milk and another 2 tsp cornstarch mixed into a tblsp of water...let it boil until it was thickened...and it was PERFECT!! I cannot get over how tender the meat turned out--it just fell apart and flaked so easily! I may do this method with just salt and pepper in the future to use with some BBQ sauce to make BBQ pork. Have no doubts...try this recipe! You will love it!!!!

Hey! I just wanted to give an up date. I made this again but with Lipton's mushroom onion soup mix and it is FANTASTIC!!!!! I waited the four hours like in the recipe. still well worth the wait!

So easy! I had a 2.25lb loin - put it in for 65 min covered, 15 uncovered and dried mine out a bit, but the flavors was plenty and good for my first try cooking this type of meat! Thanks for this recipe. The only thing I plan to change in the future is my cook time. Saved
