Instructions

  1. Step 1: Preheat oven to 425°F. Rub 1.5 lbs pork tenderloin all over with 2 tbsp olive oil, 1 tbsp fresh thyme, 1 tbsp chopped rosemary, 3 minced garlic cloves, 1 tsp salt, and 1/2 tsp black pepper.
  2. Step 2: Place the pork on a roasting pan and roast in the oven for 20-25 minutes, turning once halfway, until internal temperature reaches 145°F. Remove from oven and let rest for 10 minutes.
  3. Step 3: While the pork rests, pour 1/2 cup dry white wine into a skillet over medium heat, scraping up browned bits from the roasting pan. Bring to a simmer and reduce by half, about 3-4 minutes.
  4. Step 4: Reduce heat to low and whisk in 2 tbsp Dijon mustard, 1/4 cup heavy cream, and 1 tbsp butter until sauce is smooth and thickened. Slice the pork and serve drizzled with the mustard sauce.
