Step‑by‑Step Instructions for Grilled Beef Tenderloin Crostini with Béarnaise
Step 1: Prepare the Beef
Remove your beef tenderloin filets from the refrigerator and let them sit at room temperature for about 30 minutes. This step is key for even cooking. Meanwhile, you can gather your ingredients and ensure your grill is clean and ready for the delicious grilled beef tenderloin crostini.
Step 2: Preheat the Grill
Set your grill to medium-high heat, around 350-375°F. This temperature will create the perfect environment for toasting the baguette. While the grill heats, it’s a good time to slice your baguette to the desired thickness and prepare for the next steps in creating the grilled beef tenderloin crostini with béarnaise.
Step 3: Slice and Brush the Baguette
Slice the baguette into ½-inch thick pieces at a 45-degree angle to enhance its presentation. Next, brush each slice with a generous amount of olive oil, ensuring they are well-coated to prevent them from drying out during grilling. This preparation will result in a deliciously crispy base for your crostini.
Step 4: Toast the Baguette
Place the oiled baguette slices on the grill for about 1-2 minutes per side, watching closely for a golden brown color that indicates they are ready to flip. Once toasted, remove them from the grill and sprinkle lightly with kosher salt for added flavor. These crispy pieces will be the perfect vessel for your beef tenderloin.
Step 5: Increase the Grill Heat
Once the baguette slices are toasted, turn the grill heat up to high, reaching about 450-475°F. This higher temperature is essential for searing the beef tenderloin, which gives it a delicious crust while keeping the inside tender and juicy. Prepare your seasonings while the grill heats up.
Step 6: Season and Grill the Beef
Season the beef tenderloin filets generously with kosher salt and freshly ground pepper. Place the seasoned filets directly on the grill and cook for about 3-5 minutes per side. Aim for an internal temperature of 125°F for a perfect medium-rare. The enticing aroma will signal that your grilled beef tenderloin is almost ready.
Step 7: Rest the Beef
Once the beef is cooked to your liking, carefully remove it from the grill and let it rest for about 10 minutes. This resting period is crucial as it allows juices to redistribute, ensuring each slice is flavorful and juicy when assembled on the crostini.
Step 8: Prepare the Béarnaise Sauce
While the beef is resting, follow the package instructions for your béarnaise sauce mix. If you’re feeling adventurous, preparing a homemade version adds an extra touch of gourmet flair to your grilled beef tenderloin crostini. The sauce should be warm and ready for assembly.
Step 9: Assemble the Crostini
To assemble your grilled beef tenderloin crostini, slice the rested beef into thin pieces. Layer these tender slices atop the toasted baguette and drizzle generously with the creamy béarnaise sauce. For a beautiful finish, garnish each crostini with freshly chopped chives or parsley, adding a vibrant touch to your impressive appetizer.

Tips for the Best Crostini
Crispy Baguette: Ensure baguette slices are perfectly grilled until golden brown to prevent sogginess when topped.
Temperature Check: Use a meat thermometer to achieve the perfect medium-rare for your grilled beef tenderloin crostini, reaching 125°F.
Fresh Assembly: Assemble crostini just before serving for maximum freshness and optimal flavor; they can sit at room temperature for up to 2 hours.
Flavorful Oil: Brush the baguette with garlic-infused olive oil for an extra depth of flavor that pairs beautifully with the béarnaise sauce.
Garnish Wisely: Garnish each crostini with fresh chives or parsley not only for aesthetics but also to enhance the overall flavor experience.
How to Store and Freeze Grilled Beef Tenderloin Crostini
Fridge: Store leftovers in an airtight container for up to 3 days, separating the beef, béarnaise sauce, and baguette to preserve their individual flavors.
Freezer: Individually wrap cooked beef and toasted baguette slices in plastic wrap and place in freezer bags for up to two months. Thaw in the fridge overnight before serving.
Reheating: To reheat the beef, gently warm in a skillet or microwave until heated through; the baguette can be refreshed in the oven for a few minutes to regain its crispness.
Assembling: Assemble the grilled beef tenderloin crostini just before serving to maintain optimal freshness, as the components can lose their texture when combined too early.

Grilled Beef Tenderloin Crostini with Béarnaise Recipe FAQs
What should I look for when selecting beef tenderloin?
Absolutely! When selecting beef tenderloin, look for a piece with good marbling and a bright red color. Avoid any cut with dark spots or an off smell, as these can indicate spoilage. Fresh beef should feel firm to the touch and have a clean, meaty aroma.
How should I store leftovers of the crostini?
Very important! Store leftover components in separate airtight containers in the refrigerator. The toasted baguette can last up to 3 days, while the beef and béarnaise should also be consumed within the same timeframe for the best flavor. When ready to enjoy, simply reassemble your crostini fresh, or opt to reheat components separately.
Can I freeze the crostini?
Certainly! To freeze, individually wrap the cooked beef and toasted baguette slices in plastic wrap, then place them in freezer bags. These can be stored in the freezer for up to 2 months. To thaw, simply move them to the fridge overnight, then reheat gently before assembly for fresh, crispy crostini.
What if my beef is not cooking evenly on the grill?
Oh no, that can happen! If your beef isn’t cooking evenly, it may be because it was too cold when placed on the grill. Ensure your beef sits at room temperature for 30 minutes prior to grilling for even cooking. Also, don’t flip it too soon; give it enough time to sear before moving it.
Are there any dietary considerations for this recipe?
Absolutely! If you’re accommodating dietary restrictions, you can easily swap out the beef for grilled chicken, portobello mushrooms, or even tofu for a vegetarian option. For gluten-free needs, opt for gluten-free baguettes. Always check the béarnaise sauce ingredients if you have allergies, as some mixes may contain gluten or dairy.
How long can I keep the prepared Béarnaise sauce?
Great question! If you prepare the Béarnaise sauce ahead of time, keep it in an airtight container in the fridge for up to 3 days. Reheat gently on low heat while stirring, as this sauce can separate if heated too quickly. This way, you can save time while ensuring a delicious crostini experience!
