Step‑by‑Step Instructions for Grilled Beef Tenderloin Crostini with Creamy Béarnaise Sauce

Step 1: Prepare the Beef
Remove the beef tenderloin filets from the refrigerator and allow them to sit at room temperature for 30 minutes. This step ensures even cooking throughout the meat. Pat the filets dry with paper towels, which helps achieve a beautiful sear on the grill, enhancing the flavors for your grilled beef tenderloin crostini.

Step 2: Preheat the Grill
While the beef comes to temperature, fire up your grill. Preheat it to medium-high heat, aiming for a range of 350-375°F. This temperature is ideal for searing the beef and gives it that coveted char. Ensure the grill grates are clean to prevent sticking, which will help create perfect grill marks on the filets.

Step 3: Prepare the Baguette
Slice the baguette into ½ inch pieces at a 45-degree angle. This angle increases the surface area, allowing for more delicious crunch. Brush both sides of the baguette slices liberally with olive oil; if you desire more flavor, consider infusing the oil with garlic. The oil will help them crisp up beautifully on the grill.

Step 4: Grill the Baguette
Place the oiled baguette slices onto the preheated grill. Grill for 1-2 minutes per side, or until they are lightly toasted and golden brown. Keep a close eye on them to avoid burning; they should be crispy but not overly charred. Once toasted, sprinkle a pinch of kosher salt over each slice to enhance their flavor.

Step 5: Increase the Grill Heat
Once the baguette slices are toasted, increase the grill’s heat to high, aiming for 450-475°F. This intense heat is perfect for searing the beef quickly. Ensure the grill lid is closed while it heats up, allowing the temperature to stabilize and create excellent grilling conditions for your beef tenderloin.

Step 6: Season and Grill the Beef
Generously season the beef filets with kosher salt and fresh ground pepper. Place them on the hot grill and cook for 3-5 minutes per side, or until an instant-read thermometer reads 125°F for medium-rare. The beef should develop a lovely crust while remaining juicy and tender inside, perfect for your crostini.

Step 7: Let the Beef Rest
Once the beef filets reach the desired temperature, remove them from the grill and let them rest for approximately 10 minutes. Resting allows the juices to redistribute throughout the meat, ensuring every bite of your grilled beef tenderloin is succulent and rich. Prepare your Béarnaise sauce during this resting period.

Step 8: Prepare the Béarnaise Sauce
Follow the package instructions to prepare your Béarnaise sauce mix while the beef rests. If you’re feeling adventurous, consider making it from scratch for a gourmet touch. This rich, creamy sauce complements the grilled beef perfectly, adding a luxurious finish to your crostini.

Step 9: Assemble the Crostini
To assemble your irresistible grilled beef tenderloin crostini, place a slice of grilled beef on each toasted baguette. Drizzle a generous amount of the creamy Béarnaise sauce over the beef, allowing it to soak into the bread slightly. Finish by garnishing with freshly chopped chives or parsley for a vibrant presentation and an extra burst of flavor.

Grilled Beef Tenderloin Crostini with Creamy Béarnaise Sauce Recipe FAQs

What is the best way to select beef tenderloin for this recipe?
Absolutely! When choosing beef tenderloin, look for cuts that are bright red and have a fine marbling of fat throughout. This marbling contributes to the tenderness and flavor of the cooked meat. Generally, aim for filets that are about 2 inches thick, as this thickness allows for achieving that perfect medium-rare finish without the beef becoming dry.

How should I store leftovers from the crostini?
The best way to store leftover grilled beef tenderloin crostini is to keep each component separate. Place the toasted baguette slices and beef tenderloin in airtight containers in the fridge. They will stay fresh for up to 3 days. I recommend consuming them within that timeframe for optimal flavor and texture!

Can I freeze the grilled beef tenderloin crostini?
Yes, you can! For freezing, wrap each individual crostini in plastic wrap, then place them in aluminum foil to protect from freezer burn. Finally, store them in a freezer-safe bag. They can be frozen for up to 2 months. When you’re ready to enjoy, simply thaw them overnight in the refrigerator. Reheat in a preheated oven at 350°F (175°C) for about 10-12 minutes until warm and crispy.

What if my Béarnaise sauce curdles while making it?
No worries! If your Béarnaise sauce curdles, don’t panic. This can happen if the sauce gets too hot too quickly. Simply transfer it to a blender and gently blend it until smooth again. To prevent this in the future, always whisk gently over low heat and remove from the heat source if it starts to get too hot. Patience is key for a creamy consistency!

Can I make this recipe gluten-free for dietary preferences?
Certainly! To make this delicious dish gluten-free, all you need to do is substitute the regular baguette with a gluten-free baguette. Many grocery stores now offer a variety of gluten-free bread options that will work beautifully for the crostini base. Enjoy your culinary creation without compromising on taste!
