Ingredients
- 1 lb pork tenderloin
- 2 tbsp olive oil
- 1 tbsp fresh thyme leaves
- 1 tbsp fresh rosemary, chopped
- 2 cloves garlic cloves, minced
- 1 tsp salt
- 0.5 tsp black pepper
- 0.5 cup dry white wine
- 2 tbsp Dijon mustard
- 1 tbsp unsalted butter
Instructions
- Step 1: Preheat oven to 400°F. Pat dry 1 lb pork tenderloin and rub it all over with 2 tbsp olive oil, 1 tbsp fresh thyme leaves, 1 tbsp chopped fresh rosemary, 2 minced garlic cloves, 1 tsp salt, and 0.5 tsp black pepper.
- Step 2: Heat an oven-safe skillet over medium-high heat. Add the pork tenderloin and sear on all sides for about 2 minutes per side until golden brown and crusty.
- Step 3: Transfer the skillet to the preheated oven and roast the pork for 15-18 minutes until the internal temperature reaches 145°F for medium-rare.
- Step 4: Remove pork to a cutting board to rest for 5 minutes. Meanwhile, place the skillet back on medium heat and add 0.5 cup dry white wine, scraping up browned bits from the pan. Simmer for 3-4 minutes until reduced by half.
- Step 5: Whisk in 2 tbsp Dijon mustard and 1 tbsp unsalted butter, stirring until the sauce thickens slightly and becomes glossy. Slice the pork and serve drizzled with the mustard pan sauce.
