Preheat the oven to 350°F. Combine all the spices in a small bowl. Add the olive oil and whisk or stir well to combine. Allow this mixture to rest for 15 minutes. It will thicken to a paste-like consistency.
Line a small baking sheet with foil and place a wire rack over it. Rinse the roast and pat dry. Rub the spice mixture all over the roast, completely covering all sides with spices.
Roast for 60-90 minutes. Remove from the oven when the meat reaches an internal temperature of 145 degrees. Let the roast rest 15 minutes before slicing.
