Instructions

  1. Step 1: Preheat oven to 425°F. Rub 1.5 lbs pork tenderloin with 2 tbsp olive oil, 1 tbsp chopped fresh rosemary, 1 tbsp chopped fresh thyme, 4 minced garlic cloves, 1 tsp salt, and 1/2 tsp black pepper evenly.
  2. Step 2: Place the pork on a roasting pan and roast for 20-25 minutes until the internal temperature reaches 145°F and the exterior is golden brown. Remove and let rest for 10 minutes.
  3. Step 3: While the pork rests, in a small saucepan over medium heat, combine 1/2 cup chicken broth, 3 tbsp Dijon mustard, and 1/2 cup heavy cream. Stir continuously until the sauce thickens slightly, about 5 minutes.
  4. Step 4: Remove the sauce from heat and whisk in 1 tbsp butter until smooth and glossy.
  5. Step 5: Slice the pork tenderloin and serve drizzled with the garlic mustard sauce.
