Preheat oven to 500 degrees Fahrenheit.
Set venison roast in roasting pan. Use paper towels to dry it. (Throw away paper towels.)
Pour olive oil over the roast. Be sure it is completely covered so there is a thin layer of olive oil over it.
Sprinkle nutmeg, garlic power, kosher salt, and pepper all over the roast. Use more spices and salt if the amount is not enough to cover the roast.
Put roast in oven and turn down to 350 degrees Fahrenheit.
Roast for 18 to 20 minutes per pound for medium rare. Roast longer until desired doneness. Use a cooking thermometer and cooks until the meat registers an internal temperature of 165 degrees Fahrenheit throughout to remove all pink and chance of bacterial infection.
Remove from oven and let sit 5 minutes. Carve and enjoy.
