Ingredients
Scale
- 2 lbs center-cut beef tenderloin
- 1½ tsp coarse salt
- ½ tsp ground black pepper
- 2 Tbsp avocado oil
- 2 Tbsp unsalted butter
- 1½ Tbsp prepared horseradish
- 1½ Tbsp spicy brown mustard
- 1 lb finely chopped mushrooms
- ¼ cup finely chopped onion
- 2 medium shallots, finely chopped
- 2 garlic cloves, minced
- 1 tsp dried thyme
- 1 Tbsp Worcestershire sauce
- 6 slices prosciutto
- ½ cup unsalted butter, melted (for dough)
- 2 large eggs (for dough)
- 1 cup finely milled almond flour (or sunflower seed flour)
- ½ cup coconut flour
- ½ tsp salt
- 2 cups shredded mozzarella cheese
- 1 egg (for egg wash)
- 1 Tbsp water (for egg wash)
Instructions
- Mix almond flour, coconut flour, and salt. Add melted butter and eggs, mix well. Melt mozzarella and knead in until cohesive. Chill 20 minutes.
- Trim and tie beef tenderloin, season with salt and pepper. Sear on all sides in hot avocado oil. Let cool.
- In same skillet, melt butter. Add onion, garlic, shallots, thyme, Worcestershire sauce, and mushrooms. Cook until moisture evaporates. Cool completely.
- Mix horseradish and mustard, spread over cooled beef. Layer prosciutto and mushroom mixture on plastic wrap, place beef in center, roll tightly, and chill for 20 minutes.
- Roll dough to ¼-inch thick between parchment. Unwrap beef and place in center of dough. Brush edges with egg wash, fold and seal dough. Chill for 15 minutes.
- Place seam-side down on lined baking sheet. Brush with egg wash, score top, and sprinkle with coarse salt. Bake at 400°F for 30–35 minutes or until crust is golden and internal temp is 125–130°F. Rest 10 minutes before slicing.
Notes
Chill the dough for easier handling. Be sure to fully cook out mushroom moisture to avoid soggy crust. Use a meat thermometer for best results. Let rest before slicing.
