Preheat oven to 350F.
Place the roast, fat side up, in a roasting pan on top of a wire rack.
Pour the avocado oil on the roast.
Next, combine the salt, pepper, garlic powder, thyme and rosemary in a bowl and mix well. Spread this mixture all over the entire roast.
Bake at 350F for 2 hours, or until the internal temperature of the roast reaches 120-125 degrees F for medium rare.
Transfer the meat to a platter, cover with foil and let it rest for 15-20 minutes before serving.
