Preheat your oven to 425°F.
Pat the pork tenderloin completely dry with paper towels. Rub 2 tbsp olive oil evenly over all sides of the pork.
Combine 1 tbsp rosemary, 1 tbsp thyme, 2 tsp garlic, 1 tsp salt, and 1/2 tsp pepper in a small bowl.
Press the herb mixture firmly onto the pork’s surface.
Heat an oven-safe skillet over medium-high heat for 2 minutes. Sear the pork for 2 minutes per side until golden brown. Transfer the skillet directly to the preheated oven.
Roast for 15-18 minutes until the internal temperature reaches 145°F.
Remove the pork from the skillet and let it rest on a cutting board for 5 minutes.
Return the skillet to medium heat and pour in 1/4 cup white wine.
Scrape the browned bits from the pan bottom with a wooden spoon.
Add 1/2 cup chicken broth and 1 tbsp Dijon mustard to the skillet.
Simmer the sauce for 3 minutes until slightly reduced.
Whisk in 2 tbsp butter until the sauce becomes glossy.
Slice the pork into 1-inch thick medallions against the grain. Drizzle the warm pan sauce over the sliced pork.
