Elk often dries out and becomes bland when it is over cooked. Making sous vide elk tenderloin means it is always perfectly cooked and incredibly juicy.

Combining the sous vide elk with a flavorful blackening rub and sweet potato mash rounds out the dish and introduces amazing flavors that still allow the elk to shine through.

Cooking Instructions for Sous Vide Blackened Elk Tenderloin with Sweet Potato Mash

For the Elk

Pre-heat a sous vide bath to 130°F (54.4°C).

Season the tenderloin with half of the blackened seasoning.

Place the elk, thyme sprigs, and olive oil in a vacuum bag or ziploc and place into the water bath for 4 hours.

For the Sweet Potato Mash

In a large pot, boil the potatoes until tender, about 30 minutes. Drain and mash with a masher, stick blender, or food processor. 

Stir in the butter, cream, syrup, vanilla extract, and spices and mix well. Taste for seasoning and add more if necessary. 

Serve garnished with a sprig of rosemary.

To Finish

Remove the meat from the bag and dry it with paper towels. Season with the remainder of the blackened seasoning. 

Heat the grapeseed oil over medium high heat. When the oil is smoking hot, sear the elk on all sides until a crust forms, about 1 minute per side. Allow to rest 5 minutes before slicing.
