Ingredients

Before we jump into the cooking action, let’s gather our ingredients:

Olive oil, for brushing
Salt and pepper, to taste

For the Beef Tenderloin:

1 lb beef tenderloin, trimmed
Salt and pepper, to taste
Olive oil, for cooking

For the Béarnaise Sauce:

2 tablespoons white wine vinegar
2 tablespoons fresh tarragon, chopped
3 egg yolks
1 stick unsalted butter, melted and hot
Salt and pepper, to taste

Now that we have our culinary toolbox ready, let’s dive into making this mouthwatering appetizer!

Steps to Make Grilled Beef Tenderloin Crostini

1. Preheat the Grill:
Heat up your grill to medium-high. As it warms up, you can start on the crostini.

2. Toast the Baguette:
Brush the sliced baguette with olive oil and sprinkle a pinch of salt and pepper. Grill the slices for about 1-2 minutes on each side until they are golden and crispy. Set aside!

3. Season the Beef:
While you’re toasting the bread, season your beef tenderloin with salt, pepper, and a drizzle of olive oil. Don’t hold back on the seasoning; the beef deserves a cozy little flavor bath!

4. Grill the Beef:
Place the tenderloin on the grill and cook for about 4-5 minutes on each side for medium-rare, or longer if you prefer it well done. Once cooked to your liking, remove it from the grill and let it rest for a few minutes—trust me, this is crucial for keeping it juicy.

5. Make the Béarnaise Sauce:
Now, the pièce de résistance! In a small saucepan, combine the white wine vinegar and half of the chopped tarragon over medium heat. Reduce until you have about 1 tablespoon of liquid left. Remove from heat and allow it to cool slightly.

In a mixing bowl, whisk the egg yolks and the vinegar mixture together until thickened. Gradually whisk in the hot melted butter until it all comes together into a creamy sauce. Season with salt, pepper, and the remaining tarragon.

6. Assemble the Crostini:
Slice the rested beef thinly. On each toasted baguette slice, place a piece of beef and drizzle with Béarnaise sauce. Voilà! You have made beautiful grilled beef tenderloin crostini!

Cooking Tips

Don’t Rush the Resting Time: Allowing the beef to rest before slicing helps retain the juices. You can use this time to pour yourself a glass of wine—because cooking is hard work after all!

Make it Your Own: Feel free to add your favorite toppings—sliced tomatoes, arugula, or even a sprinkle of goat cheese could elevate your crostini game.
Béarnaise Sauce Fancy? If your sauce looks a little lumpy, don’t worry—that’s just the beauty of homemade cooking!

Personal Anecdote

This dish became my go-to for family gatherings after my kids decided that beef in tiny portions was suddenly the best thing ever. Who knew that serving food on tiny toasts would spark excitement like that? It’s now a staple in our household, and I hope it becomes one in yours too!

FAQs

Can I substitute the beef tenderloin?
Absolutely! If you’re looking for a more budget-friendly option, flank steak or even grilled chicken would work nicely.

How can I store leftovers?
Store any leftover crostini in an airtight container for up to 2 days. However, I recommend keeping the crostini separate from the sauce to ensure they stay crispy!

Can I make the Béarnaise sauce ahead?
It’s best fresh, but you can prepare the sauce ahead of time and reheat gently over low heat, whisking continuously.
