How to Make Grilled Tenderloin Crostini with Bearnaise

Preparing the Tenderloin

Begin by seasoning your beef tenderloin generously with salt and freshly cracked pepper. This foundational step is crucial as it enhances the natural flavors of the meat. Allow it to sit at room temperature for about 30 minutes; this ensures even cooking. Meanwhile, preheat your grill to medium-high, allowing those grates to get nice and hot. When ready, place the tenderloin on the grill and sear it for about 4-5 minutes on each side, depending on your preferred level of doneness. Use a meat thermometer to check for an internal temperature of 130°F (54°C) for medium-rare. Once cooked, remove the tenderloin from the grill and let it rest for at least 10 minutes, allowing the juices to redistribute and keep the meat tender and juicy.

Toasting the Crostini

As the tenderloin rests, it’s time to prepare the crostini. Preheat your oven to 400°F (200°C). Arrange the sliced baguette on a baking sheet and brush each piece lightly with olive oil. Sprinkle a pinch of salt over the bread to enhance its flavor. Bake in the preheated oven for about 8-10 minutes, or until golden brown and crispy. The aroma of toasting bread will fill your kitchen, creating an inviting atmosphere. Once they are done, set them aside to cool slightly before assembly.

Crafting the Bearnaise

Now, let’s create the star of the showBearnaise sauce. In a small saucepan, combine the white wine vinegar, minced shallots, and half of the chopped tarragon. Heat this mixture over medium heat until it reduces by half, filling your kitchen with a fragrant aroma. Strain the mixture to remove the solids, then return the liquid to the saucepan. Whisk in the egg yolks until combined, and place the saucepan over low heat. Gradually drizzle in the melted butter while whisking continuously, ensuring the sauce emulsifies beautifully. The rich, velvety texture of the sauce will make your heart sing. Stir in the remaining tarragon and season with salt to taste. Keep the sauce warm but not hot, as it can separate if overheated.

Slicing the Tenderloin

With the tenderloin rested, it’s time to slice it into thin, even pieces. Aim for about 1/4-inch (0.6 cm) thick slices to ensure they fit perfectly on your crostini. The moment you cut into the tenderloin, the rich juices will spill out, promising a succulent bite. Arrange the slices neatly over the toasted crostini, allowing the meat to drape enticingly over the edges, inviting your guests to indulge.

Assembling the Crostini

Now comes the fun partassembly! Take your toasted crostini and place a slice of the grilled tenderloin on each piece. Generously drizzle the warm Bearnaise sauce over the meat, allowing it to cascade down the sides. For an extra touch, garnish with a sprig of fresh tarragon on top, adding a pop of color and a hint of herbal freshness. Serve immediately while the crostini are still warm, and watch as your guests are drawn to this delectable creation.

Enjoying Each Bite

As you and your guests take the first bite, the combination of textures and flavors will transport you back to that warm summer evening, reminding you that food is not just about nourishment, but about creating moments that linger in our hearts. Pair the crostini with a light red wine or a refreshing cocktail to elevate the experience even further.
