Ingredients:
For the Beef Wellington:
- 1.5 lbs beef tenderloin (center-cut fillet, about 6 inches long)
- 2 tbsp olive oil (for searing)
- Salt and pepper (to taste)
For the Mushroom Duxelles:
- 8 oz mushrooms (finely chopped)
- 2 cloves garlic (minced)
- 2 tbsp butter
- 1 tbsp fresh thyme (chopped)
- Salt and pepper (to taste)
For the Prosciutto Wrap:
- 6-8 slices of prosciutto (thinly sliced)
- 2 tbsp Dijon mustard
For the Keto Pastry:
- 1 ¾ cups almond flour
- 1 tbsp coconut flour
- 1 tsp xanthan gum
- 2 large eggs
- 1 cup mozzarella cheese (shredded)
- 2 tbsp cream cheese
- 1 tbsp butter (melted, for brushing)
Instructions:
1. Prepare the Beef:
- Preheat the oven to 400°F (200°C).
- Season the beef tenderloin generously with salt and pepper.
- Heat olive oil in a skillet over medium-high heat. Sear the beef on all sides for about 2 minutes per side until browned. Set aside to cool.
2. Mushroom Duxelles:
- In the same skillet, melt butter and add the finely chopped mushrooms, garlic, thyme, salt, and pepper.
- Cook on medium heat until the mixture becomes dry and all moisture evaporates (about 5-7 minutes). Set aside to cool.
3. Prosciutto Wrap:
- Lay out a sheet of plastic wrap. Overlap the prosciutto slices to form a layer large enough to wrap the beef.
- Spread the cooled mushroom duxelles evenly over the prosciutto.
- Brush the beef with Dijon mustard and place it in the center of the prosciutto layer.
- Using the plastic wrap, tightly roll the prosciutto around the beef and mushroom mixture. Chill in the fridge for 20-30 minutes.
4. Keto Pastry:
- In a microwave-safe bowl, melt the mozzarella cheese and cream cheese together in 30-second intervals, stirring in between until smooth.
- In a separate bowl, combine almond flour, coconut flour, xanthan gum, and eggs.
- Add the melted cheese mixture to the flour mixture and knead until a dough forms.
- Roll out the dough between two sheets of parchment paper to form a rectangle large enough to wrap the beef.
5. Assembly:
- Remove the beef from the fridge and unwrap the plastic. Place the wrapped beef in the center of the keto dough.
- Carefully wrap the dough around the beef, sealing the edges.
- Place the wrapped beef on a parchment-lined baking sheet. Brush the dough with melted butter for a golden finish.
6. Baking:
- Bake in the preheated oven for 25-30 minutes or until the pastry is golden brown and the beef reaches your preferred level of doneness (125°F for medium-rare).
- Let it rest for 10 minutes before slicing and serving.
