Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. In a small bowl, mix 3 tbsp Dijon mustard, 2 tbsp fresh thyme leaves, 4 minced garlic cloves, 2 tbsp olive oil, 1 1/2 tsp salt, and 1 tsp black pepper to create the glaze.
  2. Step 2: Place 3 lbs boneless pork loin roast on a roasting rack in a shallow pan. Brush the mustard-thyme glaze all over the pork, coating evenly.
  3. Step 3: Roast uncovered in the oven for 50-60 minutes, basting every 15 minutes with pan juices. When internal temperature reaches 145°F, remove pork and let rest for 10 minutes.
  4. Step 4: Meanwhile, place the roasting pan with pan drippings over medium heat on stovetop. Add 1/2 cup chicken broth and simmer for 5 minutes until reduced slightly to make a simple pan sauce. Slice pork loin and serve drizzled with the sauce.
