Roasted Pork Tenderloin with Fresh Plum Sauce
Description
This pork tenderloin with plum sauce is Chef John's one-pan recipe featuring caramelized red onions and shallots with balsamic vinegar and thyme.
Ingredients
•
1 tablespoon vegetable oil
•
1 pork tenderloin
•
salt and ground black pepper to taste
•
1 red onion, sliced
•
2 shallots, sliced
•
3 fresh thyme sprigs, or more to taste
•
2 firm plums, pitted and each cut into 4 wedges
•
1 cup water
•
1 tablespoon balsamic vinegar
•
1 teaspoon cold butter
Directions
1
Preheat the oven to 400 degrees F (200 degrees C).
2
Heat oil in a large, oven-proof skillet over medium-high heat. Generously season pork tenderloin with salt and black pepper. Cook tenderloin in hot oil until browned on all sides, 2 to 4 minutes per side. Transfer tenderloin to a plate and set aside.
3
Sauté onion and a pinch of salt in drippings in the skillet until onion begins to soften, 3 to 5 minutes. Add shallots; reduce heat to medium. Cook and stir until onion and shallots are golden brown and caramelized, about 10 minutes.
4
Stir thyme into onion mixture, then place tenderloin on top. Set plums, skin-side down, around tenderloin. Transfer the skillet to the preheated oven.
5
Cook until pork is slightly pink in the center, about 20 minutes. An instant-read thermometer inserted into the center should read at least 145 degrees F (63 degrees C). Transfer pork and plums to a clean plate; cover with aluminum foil to keep warm.
6
Place the skillet over medium-high heat. Pour water and vinegar into onion mixture. Bring to a boil while scraping the browned bits of food off of the bottom of the pan with a wooden spoon. Cook and stir until liquid is reduced by half, 5 to 10 minutes. Remove from heat. Whisk in cold butter until melted and sauce is shiny.

Pour sauce over sliced pork and plums to serve.
