Beef Tenderloin Parmesan Crostini is an elegant appetizer featuring seared slices of tender beef on crispy baguette rounds, topped with a rich and creamy Parmesan sauce, fresh herbs, and optional greens for a flavorful and sophisticated bite.

Ingredients

Meat

  • 1 pound beef tenderloin, trimmed

Bread

  • 1 French baguette, sliced into 1/2-inch rounds

Dairy

  • 1/2 cup heavy cream
  • 1/2 cup grated Parmesan cheese

Condiments

  • 1 tablespoon Dijon mustard

Aromatics and Oils

  • 2 cloves garlic, minced
  • 1 tablespoon olive oil

Seasonings

  • Salt and freshly ground black pepper, to taste

Herbs and Greens

  • 1 tablespoon fresh chives, chopped
  • 1 tablespoon fresh parsley, chopped
  • Arugula or microgreens, for garnish (optional)

Instructions

  1. Season and Sear the Beef: Pat the beef tenderloin dry with paper towels and season all sides generously with salt and freshly ground black pepper. In a large skillet, heat olive oil over medium-high heat. Sear the beef for 4 to 6 minutes per side for medium-rare, or until it reaches your preferred level of doneness. Remove from heat, transfer to a cutting board, and allow to rest for 10 minutes before slicing thinly.
  2. Toast the Baguette Slices: Preheat oven to 400°F. Arrange baguette slices in a single layer on a baking sheet. Lightly drizzle with olive oil and sprinkle with salt. Bake for 8 to 10 minutes until crisp and golden. Remove and allow to cool briefly.
  3. Prepare Parmesan Cream Sauce: In a small saucepan over medium heat, combine heavy cream, minced garlic, and Dijon mustard. Bring to a gentle simmer while stirring regularly. Gradually add grated Parmesan cheese, whisking until the sauce becomes smooth and creamy. Simmer for an additional 2 to 3 minutes until thickened. Adjust seasoning with salt and pepper as desired.
  4. Assemble the Crostini: Place one slice of seared beef tenderloin onto each toasted baguette round. Spoon a generous amount of warm Parmesan cream sauce over the beef.
  5. Garnish and Serve: Top each crostini with chopped chives, parsley, and arugula or microgreens as desired. Arrange on a serving platter and serve immediately for best results.

Notes

  • Beef tenderloin cook time depends on thickness and desired doneness. Use a meat thermometer to ensure perfect results (medium-rare 135°F internal).
  • For a crispier crostini, allow the toasted baguette slices to cool completely before assembling.
  • Parmesan cream sauce can be made ahead and gently reheated before serving.
  • Optional greens add freshness and color but can be omitted if preferred.
