Juicy grilled tenderloin sits atop crisp baguette slices, finished with a luxurious Béarnaise sauce made from scratch.

Ingredients
4 slices beef tenderloin (about 1 lb center-cut)
1 French baguette, sliced into ½-inch rounds
2 tablespoons olive oil
1 teaspoon kosher salt
1 teaspoon freshly cracked black pepper
3 large egg yolks
2 tablespoons white wine vinegar
1 small shallot, finely chopped
1 tablespoon fresh tarragon, chopped (divided)
½ cup unsalted butter, melted
1 tablespoon chopped fresh chives (for garnish, optional)
Instructions
1. Pat the beef tenderloin dry and season with salt and black pepper.
2. Heat grill or cast iron pan over medium-high heat. Sear tenderloin for 3–4 minutes per side until medium-rare. Remove and rest for 10 minutes.
3. While the beef rests, slice the baguette into ½-inch rounds. Brush both sides with olive oil. Toast under broiler or in toaster oven until golden and crisp (2–3 minutes per side).
4. To make Béarnaise: Combine vinegar, chopped shallots, and half the tarragon in a small saucepan. Simmer until reduced by half. Strain and cool slightly.
5. Whisk egg yolks with the vinegar reduction over low heat. Slowly add melted butter while whisking constantly until thickened. Stir in remaining tarragon.
6. Thinly slice the rested tenderloin. Place a slice of beef on each toasted baguette round.
7. Spoon warm Béarnaise sauce over each crostini and garnish with chopped chives.
8. Serve immediately while warm or at room temperature.
Notes
For best results, use a meat thermometer to ensure medium-rare beef (about 130°F internal temperature).
Béarnaise sauce can be kept warm over a double boiler, but avoid overheating or it may split.
Assemble just before serving to preserve crostini crunch.
