Perfect Roasted Pork Tenderloin Recipe With Apples

Steps:

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

Steps:

• Preheat oven to 450°F. Season pork with salt and pepper.
• Heat 2 tablespoons oil in large nonstick ovenproof skillet over medium-high heat. Add pork and sear until all sides are brown, turning occasionally, about 5 minutes. Transfer pork to plate. Cool slightly. Spread mustard over top and sides of pork; press fennel seeds into mustard. Add remaining 1 tablespoon oil to skillet. Add onion slices and apples; sauté over medium heat until golden, about 5 minutes. Spread evenly in skillet and sprinkle with salt and pepper. Place pork atop apple-onion mixture.
• Transfer skillet to oven and roast until apple-onion mixture is soft and brown and meat thermometer inserted into center of pork registers 150°F, about 15 minutes. Transfer pork to platter and tent with foil. Let stand 5 minutes.
• Meanwhile, pour white wine over apple-onion mixture in skillet. Stir mixture over high heat until slightly reduced, about 2 minutes. Cut pork on diagonal into 1/2-inch-thick slices. Spoon apple-onion mixture onto plates. Top with pork and serve.
