Traeger Beef Wellington Recipe

Beef Wellington is a timeless dish, renowned for its flavors and textures. Quality ingredients really matter for this one: beef tenderloin, flavorful duxelles made from a variety of mushrooms, and the delicate crunch of puff pastry. Cooking it on a pellet grill like the Traeger adds a subtle smokiness from the wood fire flavor, taking the meal to a whole new level.

Cooking Methods: The Pellet Grill Advantage

The use of a pellet grill introduces a unique flavor to the Beef Wellington that can’t be replicated in a conventional oven. The grill’s consistent temperature control ensures the beef is cooked evenly while the puff pastry gets to that perfect golden-brown crust. If you don’t have a pellet grill, you can still make this in your oven, which is the traditional way to prepare Beef Wellington. In this recipe, we’re using the Traeger as a big, wood-fired outdoor oven, so the times and temperatures transfer between methods.

Why you’ll love this dish…

  • Elegant Presentation: The finished dish is visually stunning with its golden pastry and succulent beef.
  • Unique Flavor: Cooking on a pellet grill adds a wood-fired flavor that enhances the overall taste.
  • Versatility: Easily adapted for various dietary preferences or cooking methods.
  • Bold Flavor: The combination of tender beef, rich mushrooms, and a touch of smoke makes every bite unforgettable.

When you say cook on a pellet grill, do you mean smoke? I have a Traeger pellet smoker, I can only smoke on mine, not grill without the smoke.

You can grill and smoke on the Traeger. If you are cooking above about 300°, whatever you are cooking won't really get much smoke. You'll be able to tell it was cooked over wood fire, for sure, but it won't be "smoked". It is all about temperatures. We often use our Traeger as a big outdoor oven. It is very versatile.
