This pork loin recipe is perfect for a special occasion or a family dinner. The mustard and herb crust adds a tangy and flavorful touch to the pork. Start by blending Dijon mustard, garlic, thyme, rosemary, salt, and pepper in the food processor. Rub the mixture all over the pork loin and let it marinate for at least an hour. Preheat the oven to 375°F and roast the pork loin for about 45 minutes or until the internal temperature reaches 145°F. Let it rest for 10 minutes before slicing and serving.
