First thing, ensure your venison roast is at room temperature. If using a venison loin or backstrap, trim any excess fat.
Place the venison in a vacuum seal bag or a ziplock bag using the water displacement method. If adding herbs or spices like juniper berries, do so before sealing.
Set your sous vide cooker to the desired temperature. For medium-rare venison, 130°F is ideal; however, for our recipe, we're aiming for a level of doneness akin to medium, hence the 150°F setting.
Place your sealed bag in the water bath. Ensure it's fully submerged. For a 2lb roast, a minimum of 6 hours is needed.
After the sous vide cook, remove the venison from the bag. Pat it dry with a paper towel to ensure proper searing.
Heat a very hot cast iron pan with a little oil or butter.
Sear each side of the venison roast for 30 seconds to a minute over medium-high heat. This step adds a delicious crust to the tender meat.
Let the roast rest for a few minutes, then slice against the grain.
Serve with sides like roasted vegetables or perhaps a red wine sauce.
