Ingredients Breakdown

This recipe makes 6 crostini, perfect for a small gathering or appetizer course.

For the Crostini

• 1 loaf Baguette or gluten-free baguette
• 2 tablespoons Olive oil, for brushing

For the Beef

• 2 pieces Beef tenderloin filets, 2-inch thick
• 1 teaspoon Kosher salt
• 1 teaspoon Fresh ground black pepper

For the Sauce

• 1 package Béarnaise sauce mix or homemade Béarnaise sauce

For Garnishing

• 2 tablespoons Fresh chives (or fresh parsley as an alternative)

Tools & Equipment Needed

• Grill
• Baking sheet
• Meat thermometer
• Knife and cutting board
• Brush for olive oil
• Small bowl or container for Béarnaise sauce

Step-by-Step Instructions

Step 1: Prepare the Beef

Remove the beef tenderloin filets from the refrigerator 30 minutes before grilling. This helps ensure even cooking and prevents a cold center.

Step 2: Preheat the Grill

Set your grill to medium-high heat, approximately 350–375°F. This is perfect for grilling the crostini first and then searing the beef.

Step 3: Prepare the Crostini

Slice the baguette at a 45-degree angle into ½-inch thick pieces. Brush each slice lightly with olive oil.

Grill the baguette slices for 1–2 minutes per side until lightly toasted. You want them crisp but not burnt—this will give a perfect base for the beef and sauce.

Step 4: Sear the Beef

Turn your grill to high heat, around 450–475°F, for searing the beef.

Season the beef tenderloin filets generously with kosher salt and freshly ground black pepper.

Grill each filet for 3–5 minutes per side, or until the internal temperature reaches 125°F for medium-rare. Adjust time slightly for desired doneness.

Pro Tip: Use a meat thermometer to ensure perfect results; overcooking can compromise tenderness.

Step 5: Rest the Beef

Remove the beef from the grill and let it rest for 10 minutes. This allows the juices to redistribute, keeping the meat tender and juicy.

Step 6: Prepare Béarnaise Sauce

While the beef rests, prepare the Béarnaise sauce according to package instructions, or make a homemade version if preferred. Keep warm until ready to serve.

Step 7: Assemble the Crostini

Slice the rested beef thinly and layer it on the toasted crostini slices.

Drizzle each crostini with Béarnaise sauce and garnish with fresh chives or parsley.

Step 8: Serve and Enjoy

Serve immediately while the crostini are crisp and the beef is warm. This elegant presentation will impress your guests and makes for a visually stunning appetizer.

Tips & Variations

• Bread Options: Use a gluten-free baguette for a gluten-sensitive crowd or sourdough for a tangier flavor.
• Béarnaise Alternatives: Hollandaise, garlic aioli, or a simple mustard cream sauce work as well.
• Beef Doneness: Adjust grilling time for medium or medium-well preferences; 125°F internal temp is ideal for medium-rare.
• Garnish Ideas: Microgreens or thinly sliced radish add color and texture.
• Make Ahead: Slice the crostini and prep the sauce in advance for quick assembly.

Flavor Profile & Pairings

The combination of flavors in this crostini is elegant and well-balanced:

• Tender, Juicy Beef: Rich and meaty, melts in your mouth.
• Crisp Crostini: Provides the perfect crunch to contrast the tender beef.
• Silky Béarnaise Sauce: Adds richness and a subtle tang from tarragon (if homemade).
• Fresh Herbs: Chives or parsley add a bright finish.
