Add all of the ingredients together in a zip-top bag or bowl with a lid and mariante for at least 4 hours, but up to overnight in the fridge.
Once marinaded, remove the venison from the marinade and fridge and allow it to come to room temperature on a paper towel while you preheat the grill. Pat it dry well to remove a lot of the excess.
Preheat to grill to medium-high, about 450-500F.
When the grill is hot, directly lay the venison on the grates and cook until the internal temperature reaches about 117-122F if you’re looking for medium rare. Cook times vary due to the thickness of the backstrap/loin due to the size of your animal so it’s best to cook to temperature, not set time.
Let the meat rest for a least 10 minutes before slicing and serving. I usually add fresh cracked pepper and flakey salt before serving. Enjoy!
