Ingredients

For the beef:

• 8 oz beef tenderloin, trimmed
• 1 tsp olive oil
• Salt and pepper, to taste

For the crostini:

• 12 baguette slices (½ inch thick)
• Olive oil spray or drizzle

For the Parmesan cream sauce:

• 1 tbsp light butter
• 1 clove garlic, minced
• 1 tbsp all-purpose flour
• ¾ cup low-fat milk
• ¼ cup grated Parmesan cheese
• Salt and black pepper, to taste

Optional garnish: chopped chives, arugula, or shaved Parmesan

Instructions

1. Prep the Crostini
Preheat oven to 375°F (190°C). Arrange baguette slices on a baking sheet and lightly spray or brush with olive oil. Bake for 6–8 minutes, or until golden and crisp. Set aside.

2. Cook the Beef
Season tenderloin with salt and pepper. Heat olive oil in a skillet over medium-high heat. Sear beef for 2–3 minutes per side (for medium-rare), then let it rest for 5 minutes before slicing thinly against the grain.

3. Make the Parmesan Cream Sauce
In a small saucepan, melt butter over medium heat. Add garlic and cook for 30 seconds. Stir in flour and cook for 1 minute. Slowly whisk in milk and cook until slightly thickened. Add Parmesan cheese, stirring until melted and smooth. Season to taste.

4. Assemble the Crostini
Top each toasted baguette slice with a piece of sliced beef. Drizzle with warm Parmesan sauce and garnish if desired. Serve immediately while warm.

Tips for Success

• Don’t Overcook the Beef – Tenderloin is best medium-rare to medium for maximum tenderness.
• Use Fresh Parmesan – Freshly grated cheese gives the sauce better texture and flavor.
• Serve Warm – Assemble just before serving to keep the crostini crisp and the sauce silky.
• Get Creative with Toppings – A sprinkle of fresh herbs or arugula can elevate presentation and flavor.
