Equipment

- Frying pan
- Food processor
- Parchment paper
- Baking sheet
Ingredients
Beef Tenderloin
- 2 lbs beef tenderloin at room temperature
- Salt and pepper to taste
- 2 tbsp olive oil
Mushroom Duxelles
- 1 lb button mushrooms finely chopped
- 2 shallots minced
- 4 cloves garlic minced
- 1 tbsp fresh thyme leaves
- 2 tbsp unsalted butter
Keto Pastry
- 1 ½ cups almond flour
- ¼ cup coconut flour
- 1 tsp xanthan gum
- ½ tsp salt
- ½ cup unsalted butter chilled and diced
- 1 large egg beaten
Instructions
- Preheat your oven to 400°F (200°C). Season the beef tenderloin generously with salt and pepper. Heat olive oil in a frying pan over high heat. Sear the beef on all sides until browned, about 2 minutes per side. Remove from heat and let cool.
- In a food processor, pulse the mushrooms, shallots, garlic, and thyme until finely chopped. Melt butter in a pan over medium heat, add the mushroom mixture, and sauté until the water evaporates and the mixture becomes paste-like, about 10 minutes. Season with salt and pepper, then remove from heat and let cool.
- In a mixing bowl, combine almond flour, coconut flour, xanthan gum, and salt. Cut in the chilled butter until the mixture resembles coarse crumbs. Add the beaten egg and mix until a dough forms. Roll out the dough between two sheets of parchment paper to a size that will wrap around the beef.
- Spread the mushroom duxelles evenly over the keto pastry, leaving a margin at the edges. Place the cooled beef tenderloin in the center and wrap the pastry around the beef, sealing the edges. Turn it seam side down on a baking sheet lined with parchment paper.
- Bake in the preheated oven for 25 to 30 minutes or until the pastry is golden brown and the beef reaches your desired level of doneness (135°F for medium-rare). Let the Beef Wellington rest for 10 minutes before slicing.
- Cut the Keto Beef Wellington into slices and serve immediately. Enjoy your luxurious, low-carb feast!
Notes
Ensure the beef is at room temperature before searing to ensure even cooking. Resting time for the meat is crucial for retaining juices.
