Ingredients

• 2 , 1 1/2 pound
• 2 teaspoons vegetable oil
• 1 teaspoon sea salt
• 2 tablespoons vegetable oil , divided, or more as needed
• 3 medium Granny Smith apples - peeled , cored, and sliced into eighths
• 2 medium sweet onions , sliced vertically
• 3 teaspoons chopped fresh thyme , divided
• 0.25 teaspoons ground black pepper , or to taste
• 1 tablespoon Dijon mustard
• 1 cup chicken stock
• 1 tablespoon butter

Instructions

1. 1 Preheat the oven to 425 degrees F (220 degrees C).
2. 2 Trim silver skin from pork tenderloins; pat dry using paper towels. Rub 2 teaspoons vegetable oil over tenderloins, then rub with sea salt.
3. 3 Heat 1 tablespoon vegetable oil in a large, oven-proof skillet over medium heat until it shimmers. Cook tenderloins in hot oil, rotating to brown all sides, about 10 minutes. Transfer pork to a large plate.
4. 4 Add remaining 1 tablespoon vegetable oil to any drippings in the skillet. Cook apples and onions in hot oil, stirring occasionally, until onions turn translucent, about 5 minutes; add more oil if the skillet gets dry. Season with 1 teaspoon thyme and black pepper; stir gently to combine. Remove from heat.
5. 5 Use a pastry brush to spread Dijon mustard evenly over tenderloins. Sprinkle with remaining 2 teaspoons thyme. Nestle tenderloins into the skillet with apple mixture.
6. 6 Roast, uncovered, in the preheated oven until an instant-read thermometer inserted into the center of tenderloins reads at least 145 degrees F (63 degrees C), about 15 minutes. Remove the skillet from the oven and transfer pork to a large platter. Cover with aluminum foil and let rest.
7. 7 Meanwhile, pour chicken stock into a saucepan and cook over medium-high heat until reduced by half, 8 to 10 minutes. Pour into the skillet with apple mixture. Cook over medium-high heat until boiling, about 5 minutes; stir in butter until melted.
8. 8 Slice pork and serve over apple mixture.
