Our Smoked Beef Tenderloin with Horseradish Butter is an exceptional meal. It’s easy to prepare and has an inherently rich and savory flavor, enhanced by low and slow heat. Seasoned simply with salt and pepper, this tenderloin gets a spicy finish with horseradish compound butter, flavored with shallots, garlic and lemon to up the flavor profile.About the cut: The beef tenderloin is an oblong muscle that extends along the rear portion of the spine, from about the hip bone to the thirteenth rib. It doesn't get much exercise and is encased in a thick layer of crumbly fat, which makes the meat especially tender.We made this recipe on the Highland Offset Smoker, but you can make it on your smoker.
