Step‑by‑Step Instructions for Grilled Beef Tenderloin Crostini
Step 1: Prep Beef
Begin by taking the beef tenderloin filets out of the refrigerator and allowing them to sit at room temperature for 30 minutes. This step is crucial for achieving even cooking. While the beef warms up, you can get everything else ready, creating an efficient workflow for the Grilled Beef Tenderloin Crostini.
Step 2: Prep Grill
Next, preheat your grill to a medium-high heat, reaching between 350-375°F. Use a grill thermometer to ensure perfect temperature. With the grill warming up, you’ll be ready to cook the beef to tender perfection in no time.
Step 3: Prepare Baguette
While your grill heats up, slice the baguette at a 45-degree angle into ½ inch thick pieces. This angle not only enhances the presentation but also provides a larger surface for toasting. Brush both sides of each slice generously with olive oil to ensure a delightful crispness.
Step 4: Toast Baguette
Place the sliced baguette on the preheated grill and toast for 1-2 minutes on each side, until they turn golden brown and slightly crispy. Keep an eye on them, as they can burn quickly. Once toasted, sprinkle a light pinch of kosher salt over the slices to elevate the flavor.
Step 5: Grill Beef
Increase the grill’s heat to high, aiming for a sizzling 450-475°F. Season the beef tenderloin generously with kosher salt and fresh ground pepper. Grill the beef for 3-5 minutes per side, using a meat thermometer to check for an internal temperature of 125°F for medium-rare, ensuring juicy, rich bites for your Grilled Beef Tenderloin Crostini.
Step 6: Rest Beef
Once grilled to perfection, transfer the beef tenderloin filets to a cutting board and let them rest for 10 minutes. This resting period allows the juices to redistribute, ensuring each slice is tender and moist. While the beef rests, you can prepare your Béarnaise sauce.
Step 7: Prepare Sauce
During the beef’s resting time, prepare the Béarnaise sauce according to the package instructions or your homemade recipe. This rich, creamy sauce will complement the flavors of the tenderloin beautifully. Make sure to have everything ready for the final assembly of your Grilled Beef Tenderloin Crostini!
Step 8: Assemble Crostini
To assemble the crostini, place a slice of grilled beef on top of each toasted baguette piece. Drizzle the creamy Béarnaise sauce generously over the beef. Finish off the dish by garnishing with freshly chopped chives or parsley for a touch of color and flavor. Serve immediately for the best experience!

Expert Tips for Grilled Beef Tenderloin Crostini
- Perfectly Toasted Baguette: Ensure your baguette slices are toasted until golden brown for that satisfying crunch. Undercooking can lead to a soggy base.
