✔ Ingredients (Serves 12-16 crostini) :

For the Beef Tenderloin:

  • 1 lb (450g) beef tenderloin, trimmed

  • 1 tsp sea salt

  • 1 tsp freshly cracked black pepper

  • 2 tbsp olive oil

  • 2 sprigs fresh rosemary (or 1 tsp dried)

  • 2 sprigs fresh thyme

For the Béarnaise Sauce:

  • 3 large egg yolks

  • ½ cup (1 stick) unsalted butter, melted

  • 1 tbsp white wine vinegar

  • 1 tbsp fresh tarragon, finely chopped

  • 1 tsp shallot, minced

  • ¼ tsp salt

  • ¼ tsp black pepper

For the Crostini:

  • 1 French baguette, sliced into ½-inch pieces

  • 2 tbsp olive oil

  • ¼ tsp sea salt

Garnish (optional):

  • Microgreens or fresh parsley

  • Lemon zest

✔ Directions :

1. Prepare the Beef Tenderloin:

  • Let the beef sit at room temperature for 30 minutes. Pat dry and season with salt and pepper.

  • Heat olive oil in a grill pan or skillet over medium-high heat. Add rosemary and thyme, then sear the beef for 3–4 minutes per side for medium-rare (internal temp: 130°F). Rest for 10 minutes before slicing thinly.

2. Make the Béarnaise Sauce:

  • In a blender, combine egg yolks, vinegar, shallot, and tarragon. Blend until smooth.

  • With the blender running, slowly drizzle in melted butter until emulsified. Season with salt and pepper. Keep warm in a heatproof bowl over simmering water.

3. Toast the Crostini:

Preheat the oven to 375°F. Brush baguette slices with olive oil, sprinkle with salt, and bake for 8–10 minutes until golden and crisp.

4. Assemble:

  • Top each crostini with a slice of beef. Drizzle with béarnaise sauce and garnish with herbs or lemon zest. Serve immediately.

How To Make Grilled Beef Tenderloin Crostini with Béarnaise Sauce

✔ Frequently Asked Questions :

  1. Can I substitute dried tarragon for fresh?
    Yes, but use ⅓ the amount (1 tsp dried = 1 tbsp fresh). Fresh tarragon offers a brighter flavor.

  2. Can I make the béarnaise sauce ahead?
    Prepare it 1 hour in advance and keep warm. Reheat gently to avoid curdling.

  3. What wine pairs well with this dish?
    A dry white wine like Sauvignon Blanc complements the béarnaise’s acidity.

  4. How do I prevent overcooking the beef?
    Use a meat thermometer and remove it at 125°F—it’ll rise to 130°F while resting.

  5. Can I use gluten-free bread?
    Absolutely! Opt for a crusty gluten-free baguette for the crostini.

✔ Tools You’ll Need :

  • Grill pan or cast-iron skillet

  • Meat thermometer

  • Blender or immersion blender
