Whisk oil, Worcestershire sauce, crushed garlic cloves, sea salt, and black pepper in a small bowl or measuring cup.
Thaw venison backstraps the pat dry with paper towels. Add to a shallow dish and drizzle with marinade until submerged. Cover with Saran Wrap or foil, then marinate for 4 or more hours.
Backstraps Cooking Instructions
Heat a cast iron skillet over medium high heat until smoking hot. Add a tablespoon or two of tallow, or other fat.
Place 2 to 4 marinated steaks (depending on pan and steak size) and sear for 1 to 2 minutes per side. Tent steaks with foil and allow to rest for at least 5 minutes. This allows the juices to redistribute throughout the steaks.
Notes
Backstrap is one of the most tender cuts of meat. You don't want to overcook it. You want to aim for rare to medium rare. If using a meat thermometer, remove the steaks from the pan when they reach 125-130F.
I like to add venison backstrap and this marinade to a ziplock bag and freeze them together so that when I feel like eating venison, all I have to do is thaw and cook it.
Backstrap can also be prepared on a grill, or in the oven, as long as it's cooked using high heat and only for a few minutes per side.
Leftover backstrap can be stored in an airtight container in the refrigerator for up to 3 to 5 days.
