Step‑by‑Step Instructions for Grilled Beef Tenderloin Crostini with Creamy Béarnaise Sauce
Step 1: Prep Beef
Remove the beef tenderloin filets from the refrigerator 30 minutes before cooking; this allows for even cooking. While the beef warms up, pat it dry with paper towels to ensure a good sear on the grill. This step is crucial for achieving a beautifully grilled flavor for your crostini.
Step 2: Prep Grill
Preheat your grill to medium-high heat, ideally between 350-375°F. Make sure the grill grates are clean and lightly oiled to prevent sticking. A well-prepared grill will give your beef tenderloin the perfect smoky char, elevating these crostini to gourmet status.
Step 3: Prepare Baguette
While the grill is heating, slice the baguette diagonally into ½ inch pieces. Brush both sides of these slices generously with olive oil to enhance flavor and crispiness. This preparation will create that perfect crunchy base for your Grilled Beef Tenderloin Crostini.
Step 4: Toast Baguette
Once the grill reaches the desired temperature, place the baguette slices on the grill. Toast them for about 1-2 minutes on each side until they are lightly golden and crispy. Keep a close eye on them to prevent burning, and sprinkle with a pinch of salt once removed to amplify their savory taste.
Step 5: Grill Beef
Increase the grill temperature to high, around 450-475°F. Season the beef tenderloin filets with kosher salt and fresh ground pepper, ensuring an even coating. Grill for about 3-5 minutes on each side until the internal temperature reaches 125°F for perfect medium-rare. This will create those tantalizing flavors ideal for your crostini.
Step 6: Rest Meat
After grilling, remove the beef filets from the heat and let them rest for 10 minutes. This resting period is vital as it allows the juices to redistribute, resulting in a tender, juicy bite. Meanwhile, you can prepare your Béarnaise sauce to serve alongside the crispy crostini.
Step 7: Prepare Sauce
While the beef is resting, make the Béarnaise sauce according to the package instructions. This creamy, herb-infused sauce is the star of the dish and complements the grilled beef beautifully. If you’re feeling ambitious, a homemade blend takes these crostini to an even more delectable level.
Step 8: Assemble Crostini
To create the perfect Grilled Beef Tenderloin Crostini, layer slices of the rested beef on top of the toasted baguette. Drizzle with the creamy Béarnaise sauce and garnish with fresh chives for a vibrant pop of color. Serve immediately to ensure that every bite of this gourmet appetizer is enjoyed at its best.

Expert Tips for Grilled Beef Tenderloin
-
Temperature Matters: Use a meat thermometer to ensure your beef tenderloin reaches an internal temperature of 125°F for perfectly medium-rare crostini.
-
Toast to Perfection: Always toast your baguette slices until golden brown; under-toasting can result in sogginess when assembling the crostini.
-
Let It Rest: Never skip the resting period for the beef after grilling; it helps retain the juices, ensuring a tender bite for your grilled beef tenderloin.
-
Sauce Smoothness: If using homemade Béarnaise sauce, reheat it gently before serving to maintain a smooth texture; avoid overcooking.
-
Experiment Wisely: Feel free to try protein swaps, but remember that each has a unique cooking time; adjust as needed for the best results.

Make Ahead Options
These delightful Grilled Beef Tenderloin Crostini with Béarnaise Sauce are perfect for meal prep enthusiasts! You can prepare the baguette slices and toast them up to 12 hours in advance, ensuring they stay crispy by storing them in an airtight container at room temperature.
