Short Description

Beef Tenderloin Crostini with Parmesan Cream Sauce is a sophisticated yet simple appetizer featuring crispy toasted baguette slices, tender beef, and a creamy, herby Parmesan sauce. Perfect for entertaining or special occasions!

Key Ingredients

For the Crostini:

• 1 baguette, sliced into ½-inch thick pieces and toasted
• 1 pound beef tenderloin, thinly sliced
• 2 tablespoons olive oil
• Salt and pepper, to taste

For the Parmesan Cream Sauce:

• 1 cup heavy cream
• ½ cup grated Parmesan cheese
• 1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme)

Optional Garnish:

• Fresh parsley, chopped
• Additional thyme leaves
• Cracked black pepper

Tools Needed

• Baking sheet
• Large skillet
• Sharp knife
• Cutting board
• Small saucepan
• Whisk

Cooking Instructions

Step 1: Prepare the Crostini

Preheat your oven to 375°F (190°C). Arrange the baguette slices on a baking sheet and toast them for 5-7 minutes, or until they turn golden and crispy. Set aside to cool.

Step 2: Cook the Beef Tenderloin

Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Season the beef slices with salt and pepper and sear them for 1-2 minutes per side until browned but still medium-rare. Remove from the skillet and let them rest.

Step 3: Make the Parmesan Cream Sauce

Lower the heat to medium and use the same skillet to prepare the sauce. Pour in 1 cup of heavy cream and bring it to a gentle simmer.

Stir in ½ cup of grated Parmesan and thyme, whisking continuously for 2-3 minutes until the sauce thickens slightly. Remove from heat.

Step 4: Assemble the Crostini

Top each toasted baguette slice with a piece of seared beef. Drizzle a spoonful of the warm Parmesan cream sauce over the top.

Step 5: Garnish and Serve

Sprinkle with fresh parsley, additional thyme leaves, or cracked black pepper for extra flavor.

Mistakes to Avoid & Solutions

❌ Overcooking the Beef – Sear the tenderloin quickly on high heat to keep it juicy. Aim for medium-rare for the best texture.

❌ Letting the Sauce Get Too Thick – If the sauce thickens too much, add a splash of warm cream to loosen it up.

❌ Soggy Crostini – Assemble just before serving to prevent the bread from soaking up the sauce too soon.

Serving and Pairing Suggestions

These crostini shine as an appetizer but can also be part of a larger spread. Pair them with:
– A glass of Cabernet Sauvignon or Pinot Noir for a bold, complementary flavor.
– A light salad with balsamic vinaigrette to balance the richness.
– Other small bites like bruschetta or stuffed mushrooms for variety.

Storage and Reheating Tips

Storage: Keep leftover crostini components separate. Store the beef and sauce in airtight containers in the fridge for up to 2 days.

Reheating: Warm the beef gently in a skillet over low heat. Reheat the sauce on low heat, adding a splash of cream to restore its consistency.

FAQs

1. Can I use a different cut of beef?
Yes! While tenderloin is the best choice, you can also use sirloin or ribeye for a more budget-friendly option.

2. What if I don’t have fresh thyme?
Use ½ teaspoon dried thyme or substitute with rosemary or Italian seasoning for a slightly different flavor.

3. Can I make this ahead of time?
Yes! Toast the bread and cook the beef in advance. Reheat before assembling for the best texture.

4. Can I use store-bought crostini?
Absolutely! Store-bought crostini save time and work just as well.

5. How can I make this dish lighter?
Swap half-and-half for heavy cream, or use Greek yogurt instead of cream for a tangy twist.

Tips & Tricks

– Let the beef rest before slicing to retain its juices.
– Use freshly grated Parmesan for the creamiest sauce.
– Toast the bread just before serving for maximum crispiness.

Recipe Variations

Garlic Butter Crostini: Brush the baguette slices with garlic butter before toasting for an extra depth of flavor.

Blue Cheese Twist: Swap Parmesan for blue cheese in the sauce for a bold, tangy flavor.

Spicy Version: Add red pepper flakes or a drizzle of hot honey for a spicy-sweet contrast.

Mushroom Lover’s Crostini: Add sautéed mushrooms on top of the beef for an earthy touch.
