Ingredients

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

Recipe Instructions

Step 1

Preheat the oven to 425 degrees F (220 degrees C).

Step 2

Trim silver skin from pork tenderloins; pat dry using paper towels. Rub 2 teaspoons vegetable oil over tenderloins, then rub with sea salt.

Step 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.

Step 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.

Step 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.

Step 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.

Step 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.

Step 8

Slice pork and serve over apple mixture.
