Description

How to make Juicy Grilled Beef Tenderloin Crostini with tender beef, crispy crostini, and rich béarnaise that will impress your guests.

Ingredients

Scale
  • Base & Main Components:
  • 2–3 pounds beef tenderloin, center-cut, trimmed
  • 1 large baguette, preferably day-old
  • 1 cup (2 sticks) unsalted butter, cold and cubed
  • 4 large egg yolks
  • 2 large shallots, finely minced
  • 1/4 cup white wine vinegar
  • Flavor Builders:
  • 3 tablespoons fresh tarragon, finely chopped, plus more for garnish
  • 2 tablespoons fresh parsley, finely chopped
  • 2 tablespoons extra virgin olive oil, plus more for brushing
  • 1 teaspoon Dijon mustard
  • Seasonings & Spices:
  • 1 tablespoon kosher salt, plus more to taste
  • 1 teaspoon freshly ground black pepper, plus more to taste
  • Pinch of cayenne pepper (optional)
  • Finishing & Toppings:
  • 2 tablespoons fresh chives, finely snipped
  • 1 teaspoon fresh lemon juice

Instructions

  1. Prep Béarnaise Base: Mince shallots, tarragon, vinegar, and black pepper; reduce until almost dry. Slice baguette for crostini, brush with olive oil. This sets up the critical béarnaise and crostini foundation for your Juicy Grilled Beef Tenderloin Crostini.
  2. Season Beef: Pat beef tenderloin dry, rub with olive oil, salt, and pepper. Meanwhile, set up a double boiler for your béarnaise. Whisk egg yolks into the cooled shallot reduction over low heat until thickened.
  3. Emulsify Béarnaise: Slowly whisk cold, cubed butter into the egg yolk mixture, bit by bit, maintaining a steady emulsion. Remove from heat, stir in Dijon, tarragon, chives, lemon juice, and cayenne, keeping it warm for your Juicy Grilled Beef Tenderloin Crostini.
  4. Grill Beef & Toast: Grill beef tenderloin over medium-high heat to desired doneness (125-130°F for medium-rare), about 20-25 minutes. Toast baguette slices until golden and crisp, about 5-7 minutes. Let beef rest for 10 minutes.
  5. Slice Beef: Once rested, thinly slice the grilled beef tenderloin against the grain. This ensures maximum tenderness and juiciness for your crostini. Prepare these perfect slices for your Juicy Grilled Beef Tenderloin Crostini With Béarnaise.
  6. Assemble Crostini: Spoon a dollop of creamy béarnaise onto each toasted crostini. Top with a slice of the juicy grilled beef tenderloin. Arrange them beautifully on a serving platter, preparing for the final presentation.
  7. Garnish & Serve: Garnish your stunning Juicy Grilled Beef Tenderloin Crostini With Béarnaise with fresh tarragon and chives. Serve immediately to capture the perfect blend of tender beef, crispy bread, and rich sauce. Guests will love it!

Notes

Whisk cold butter slowly into béarnaise base to prevent breaking; a delicate emulsion is key.

Store leftover beef and béarnaise separately in airtight containers in the refrigerator for up to 3-4 days.

Substitute sirloin or flank steak for tenderloin if desired, slicing thinly against the grain for tenderness.

Serve immediately after assembly, garnished with fresh herbs, for optimal tenderness and crispness.

Prepare béarnaise base and grill beef up to a day ahead, storing separately; assemble just before serving.
