Say goodbye to dry pork. This easy Reverse Sear Pork Tenderloin recipe guarantees a perfectly tender, juicy center with a gorgeous, buttery herb sauce.
Dry Brine: Pat the pork tenderloin dry with paper towels. Sprinkle generously with the brown sugar, 1 ½ teaspoons of kosher salt, and black pepper. Place the tenderloin on a wire rack set inside a rimmed baking sheet. Refrigerate, uncovered, for at least 2 hours (or up to 24 hours).
1 pound pork tenderloin, 2 Tablespoon brown sugar, 1 ½ teaspoon kosher salt, ½ teaspoon ground black pepper
Prep & Preheat: Remove the pork tenderloin from the refrigerator and let it sit at room temperature for 30 to 45 minutes to take the chill off. Meanwhile, preheat your oven to 250°F.
Caramelize the Onions: Add 1 Tablespoon olive oil to a large skillet and add onions. Add the granulated sugar and ½ teaspoon of salt. Cook over medium heat, stirring frequently, until the onions are tender, deeply browned, and caramelized. Set aside when deeply caramelized leaving oil behind in the skillet.
1 medium Vidalia onion, 1 Tablespoon Olive Oil, 1 teaspoon granulated sugar, ½ teaspoon kosher salt
Slow Roast: Bake the tenderloin for about 30 minutes, or until the internal thermometer registers 110°F to 120°F. Note: Start checking after 20 minutes to prevent overcooking. Remove the baking sheet from the oven.
Sear & Baste: Heat the remaining 2 Tablespoons of olive oil in the same skillet as the onions over medium-high heat until very hot and just starting to smoke.
2 Tablespoon Olive Oil
Place the tenderloin in the hot skillet and sear until beautifully browned, about 1 ½ minutes. Flip. Immediately add the butter and fresh sage leaves to the pan. Tilt the skillet slightly and use a large spoon to continuously baste the tenderloin with the foaming sage butter for another 1 ½ minutes. Internal temperature should be 143℉.
2 Tablespoon butter, 4 to 6 fresh sage leaves
Rest the Meat: Remove the tenderloin from the skillet and transfer to a cutting board or warm plate. Allow it to rest for 3 to 5 minutes. Internal temperature will continue to rise to 140℉
Serve: Slice the juicy tenderloin and top generously with the savory caramelized onions.
Notes
