Beef Tenderloin Crostini with Parmesan Cream Sauce: A Gourmet Appetizer for Any Occasion

Preheat your oven to 375°F (190°C). Arrange the baguette slices on a baking sheet and brush each slice lightly with olive oil. Toast the bread in the oven for 8-10 minutes, or until golden brown and crispy. Once toasted, remove the crostini from the oven and rub the cut side of the garlic clove over each slice to infuse a subtle garlic flavor.

Cook the Beef Tenderloin:
While the crostini is toasting, heat 1 tablespoon of olive oil in a skillet over medium-high heat. Season the beef tenderloin with salt and pepper. Once the skillet is hot, add the beef and sear each side for about 2-3 minutes until browned and caramelized. Reduce the heat to medium-low and continue cooking for another 5-7 minutes, or until the desired level of doneness is achieved (medium-rare is ideal). Let the beef rest for 5 minutes before slicing it thinly against the grain.

Make the Parmesan Cream Sauce:
In a small saucepan, melt the butter over medium heat. Add the minced garlic and cook for 1 minute until fragrant. Pour in the heavy cream and bring the mixture to a simmer. Cook for 3-4 minutes, stirring occasionally, until the cream thickens slightly. Stir in the grated Parmesan cheese and Dijon mustard, continuing to cook and stir until the sauce is smooth and creamy. Season with salt and pepper to taste.

Assemble the Crostini:
Place the toasted crostini on a serving platter. Top each piece with a slice of beef tenderloin. Drizzle the creamy Parmesan sauce generously over the beef. Garnish with finely chopped fresh parsley for a burst of color and freshness.

Serve and Enjoy:
Serve the Beef Tenderloin Crostini with Parmesan Cream Sauce immediately, while the crostini is warm and the sauce is creamy. This appetizer is perfect for parties, gatherings, or a fancy appetizer before a main course.
