Prep Time: 45 mins • Cook Time: 20 mins • Makes: 24 bites
INGREDIENTS
- 1 tablespoon + 1 teaspoon olive oil
- 2 lbs beef tenderloin
- 1 tsp each coarse salt and freshly ground black pepper
- 2 tablespoons butter
- 6 slices prosciutto, diced
- 2 ½ cups cremini or button mushrooms, finely chopped
- 1 shallot minced
- 1 tablespoon fresh thyme chopped
- 1 tablespoon Dijon mustard
- 1 package frozen puff pastry thawed (2 sheets)
- 1 large egg, beaten
- Coarse salt for sprinkling, optional
DIRECTIONS
- Preheat oven to 400°F.
- Take the puff pastry out of the freezer one hour before starting to thaw.
- Trim and cut beef tenderloin into 24 1-inch pieces.
- Season the beef pieces with salt and pepper. Heat 1 tablespoon of oil in a large skillet or cast iron pan over medium-high heat. Sear one side of the beef pieces and quickly flip to brown the other side (about 1 minute total). Remove the pieces and set them aside to cool while preparing the filling.
- Melt butter and the remaining 1 tsp. of oil in the same skillet over medium-high heat. Add prosciutto pieces and cook until fat has rendered and pieces are crispy and brown. Add in mushrooms and minced shallot. Reduce heat to medium and sauté for about 8 to 10 minutes, stirring frequently.
- Stir in fresh thyme. Remove from heat and pat away any excess liquid. Stir in 1 tablespoon of Dijon mustard. Allow to cool while prepping puff pastry.
- On a lightly floured surface, unfold defrosted puff pastry. Using a rolling pin, roll the pastry to a 12-by-16-inch rectangle. Cut into 12 equal squares by cutting 4 long strips, then cutting each strip crosswise 3 times.
- Place a small amount of the mushroom mixture (known as duxelles) into the center of each square. Top each square with a piece of the steak. Fold the puff pastry up and over the steak, totally encasing the steak and mushroom mixture inside. Place on the prepared baking sheet with the smooth side facing upwards. Repeat with the remaining pastry, duxelles, and steak. Cut 2-3 small slits across the top of each pastry.
- Brush with egg wash and sprinkle with coarse salt.
- Bake for 15-18 minutes, or until golden brown.
- Serve with Creamy Horseradish & Mustard Dip.
