In a small bowl add the olive oil, salt, pepper, garlic, thyme, rosemary, and red pepper flakes and mix until combined.
Rub the mixture all over the roast even underneath. Place roast fat side up on a rack in a roasting pan.
Place the roasting pan in the center of the oven and bake for 30 minutes. Then reduce the heat to 375 and roast for an additional 1 hour. Or until the internal temperature reaches 145 degrees. Remove pork loin and transfer to a platter. Let rest 15 minutes before slicing.
Place roasting pan on the stovetop and add the wine or chicken stock and whisk to loosen any brown bits of flavor. Let simmer for 3-4 minutes.
Slice the pork and serve with pan juices.
Notes
You can substitute the fresh herbs for dried but use about 3/4 teaspoon of dried. Dried herbs are a lot more concentrated than fresh herbs.If you get a larger roast the cooking time will be extended.
