Ingredients
Method
Preparation
- Season the beef tenderloin with salt and pepper.
- Sear the beef in olive oil until nicely browned on all sides, then brush it with dijon mustard.
Make the Duxelles
- In a food processor, combine cleaned mushrooms, garlic, shallots, and thyme.
- Sauté the mixture in butter and oil until all the moisture evaporates and it’s beautifully fragrant. Season with salt and pepper.
Assemble
- Lay out the prosciutto, spread the mushroom mixture on top, then place the beef.
- Roll everything in puff pastry and brush with beaten egg. Sprinkle with sea salt before baking until golden brown.
Notes
Use a meat thermometer for perfect medium-rare beef. Chill pastry for a fluffier bake. Don't skip seasoning each layer for maximum flavor.
