Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Pat dry 2 lbs pork loin roast and rub all over with 3 tbsp olive oil, 4 minced garlic cloves, 2 tbsp chopped fresh thyme, 1 tbsp chopped fresh rosemary, 1 tsp salt, and 1/2 tsp black pepper.
  2. Step 2: Place the pork loin on a rack in a roasting pan and roast in the preheated oven for 45-50 minutes, or until an internal temperature of 145°F is reached, turning once halfway through cooking.
  3. Step 3: Remove the pork from the pan and let it rest covered loosely with foil for 10 minutes.
  4. Step 4: Meanwhile, place the roasting pan over medium heat on the stovetop. Add 1/2 cup dry white wine and 1/2 cup chicken broth, scraping up browned bits with a wooden spoon. Simmer for 3-4 minutes until reduced by half.
  5. Step 5: Whisk in 2 tbsp whole grain mustard until the sauce thickens and coats the back of a spoon. Slice the pork and serve drizzled with the mustard pan sauce.
