Garnish: thinly sliced red radish, flaked sea salt, and fresh tarragon sprigs
Instructions
Preheat oven to 350°.
Sprinkle fillet with salt and pepper. Let stand at room temperature for 30 minutes. Pat beef dry.
In a small stainless-steel skillet, heat oil over medium-high heat. Once hot, add fillet. Cook until browned, approximately 1 minute per side. Add butter and smashed garlic. Carefully tilt pan forward so butter pools. Using a large spoon, baste fillet with pooled butter for 2 minutes.
Place skillet with fillet in oven, baking until a meat thermometer inserted in thickest part of fillet registers 130°, 3 to 4 minutes. Transfer fillet to a cutting board, and let rest for 10 minutes. Using a sharp slicing knife, slice fillet very thinly against the grain.
Line a large rimmed baking sheet with parchment paper.
Using a 2¼-inch fluted square cutter, cut 12 squares from frozen bread slices. Place bread squares in a single layer on prepared baking sheet. Cover with damp paper towels, and let thaw slightly.
Bake bread squares until lightly golden and toasted, 4 to 5 minutes per side. Let cool completely.
In a small bowl, stir together mayonnaise, tarragon, capers, lemon juice, mustard, and grated garlic to make an aïoli. Spread approximately 1 teaspoon aïoli into a circle onto each bread square. Top with rolled beef slices.
Garnish with radish slices, sea salt, and tarragon, if desired.
