Step‑by‑Step Instructions for Grilled Beef Tenderloin Crostini
Step 1: Prep Beef
Remove your beef tenderloin filets from the refrigerator and let them rest on the counter for 30 minutes prior to grilling. This step ensures even cooking throughout the meat, allowing the flavors to develop beautifully while you get everything else ready for your Grilled Beef Tenderloin Crostini.
Step 2: Prep Grill
Preheat your grill to medium-high heat, aiming for a temperature between 350 to 375°F. This hot grill is crucial for achieving the perfect sear on your beef tenderloin, enhancing its natural flavors. Ensure the grill grates are clean and well-oiled to prevent sticking.
Step 3: Prepare Baguette
While the grill heats, slice your baguette at a 45-degree angle into ½-inch thick pieces. This angle creates a larger surface area for toasting. Brush both sides of the slices generously with olive oil, which will help achieve that golden, crispy texture when grilled.
Step 4: Toast Baguette
Place the baguette slices onto the grill and toast for 1-2 minutes on each side until they are lightly golden and crisp. Keep a close eye on them to prevent burning, as this step is essential for creating the base of your Grilled Beef Tenderloin Crostini that complements the juicy beef perfectly.
Step 5: Increase Heat
Once the baguette is toasted, turn the grill up to high, reaching temperatures of 450-475°F. This higher heat is pivotal for searing the beef tenderloin, locking in those mouthwatering flavors while creating a delicious crust that contrasts the tender interior.
Step 6: Season & Grill Beef
Generously season the beef filets on both sides with kosher salt and fresh ground pepper. Grill the filets for approximately 3-5 minutes on each side. Use a meat thermometer to check for an internal temperature of 125°F for medium-rare; this ensures your beef tenderloin is perfectly cooked to enhance your crostini.
Step 7: Rest Meat
After grilling, remove the beef tenderloin from the grill and let it rest on a plate for 10 minutes. This resting period allows the juices to redistribute within the meat, resulting in even more tenderness and flavor when you assemble the Grilled Beef Tenderloin Crostini.
Step 8: Prepare Sauce
While the beef is resting, prepare your Béarnaise sauce according to the package instructions or your homemade recipe. The creamy sauce adds an exquisite richness to your crostini, so ensure it’s ready to drizzle over the beef once assembled.
Step 9: Assemble Crostini
To assemble your delicious Grilled Beef Tenderloin Crostini, layer slices of the grilled beef tenderloin atop the toasted baguette pieces. Generously drizzle the Béarnaise sauce over the top, and finish with a sprinkle of fresh chives or parsley for a vibrant and flavorful garnish.

How to Store and Freeze Grilled Beef Tenderloin Crostini
- Room Temperature: Assemble crostini just before serving to keep the baguette crisp, as leftovers will lose texture.
- Fridge: Store any uneaten grilled beef and Béarnaise sauce separately in airtight containers for up to 3 days, reheating gently before serving.
- Freezer: It’s best to freeze only the grilled beef; wrap it tightly in plastic wrap and aluminum foil for up to 3 months. Thaw in the fridge before reheating.
- Reheating: For the best results, reheat the beef in a skillet over low heat or in the oven, ensuring it’s warmed through without drying out for your Grilled Beef Tenderloin Crostini.
Make Ahead Options
These Grilled Beef Tenderloin Crostini are perfect for meal prep enthusiasts looking to save time on busy weeknights! You can prepare the Béarnaise sauce up to 3 days in advance and store it in the refrigerator; just reheat gently before serving to ensure it remains creamy and flavorful. Additionally, the baguette slices can be toasted up to 12 hours ahead and kept in an airtight container to maintain their crispness. When you’re ready to serve, simply grill the seasoned beef for 3-5 minutes per side until it reaches your desired doneness, assemble the crostini with the prepared components, and enjoy this gourmet treat that feels fresh and delicious!
