For the Beef:

For the Béarnaise Sauce:
- 1/4 cup white wine vinegar
- 1/4 cup dry white wine
- 2 tbsp shallots, finely chopped

How to Make Grilled Beef Tenderloin Crostini with Béarnaise Sauce
Step 1: Prepare the Crostini
- Preheat your oven to 400°F (200°C).
- Toss baguette slices in a mixing bowl with olive oil, salt, and pepper.
- Arrange them on a baking sheet and toast in the oven for about 8-10 minutes or until golden brown and crisp.
Step 2: Grill the Beef
- While the crostini is toasting, season the beef tenderloin with salt and pepper.
- Heat a grill pan or outdoor grill to medium-high heat and add olive oil.
- Grill the beef for about 5-7 minutes per side for medium-rare (internal temperature around 130°F/54°C). Adjust time for your desired doneness.
- Let the beef rest for a few minutes before slicing it thinly.
Step 3: Make the Béarnaise Sauce
- In a small saucepan, combine white wine vinegar, white wine, shallots, and tarragon. Simmer until reduced by half.
- In a bowl, whisk the egg yolks until frothy. Gradually whisk in the melted butter and then slowly add the reduction until it’s all mixed.
- Season the sauce with salt and pepper to taste. Remember, we want that rich, tangy flavor to shine through!
Step 4: Assemble the Crostini
- Top each crispy baguette slice with a slice of the grilled beef.
- Drizzle your homemade béarnaise sauce generously over the beef.
- If you’re feeling fancy, garnish with fresh tarragon!
Cooking Tips
- Don’t have a grill? No worries! A grill pan or even broiling the beef in the oven will work just fine.
- Béarnaise sauce looking wonky? Sometimes it separates. Just whisk it back together; it’s all part of the cooking adventure!
