Simple Method
Cooking steak can sometimes feel a bit intimidating for beginners. Don’t worry, I will guide you through every step. We start by grilling the beef quickly to get a perfect golden crust. The baguette rounds get toasted right on the grill for extra flavor.
The sauce comes together over a gentle pot of simmering water. You just need a steady hand and a whisk. This method ensures your sauce is silky and smooth every time. Even if you have never made Béarnaise, you can do this easily.
Ingredients You’ll Need
Most of these items are likely already in your kitchen or easy to find. Fresh herbs make a huge difference in the final flavor profile.
- 1 lb beef tenderloin, trimmed
- 1 French baguette, sliced into 1/2-inch rounds
- 2 tbsp olive oil
- 1 tsp kosher salt
- 1/2 tsp freshly ground black pepper
- 3 large egg yolks
- 1 tbsp tarragon vinegar
- 1/2 cup unsalted butter, melted and warm
- 1 tbsp fresh tarragon, finely chopped
- 1 small shallot, finely minced
- 1 tsp fresh lemon juice
Step-by-Step
- Preheat the grill to medium-high heat (approximately 400°F).
- Brush baguette slices with olive oil and grill for 1 minute per side until toasted and marked; set aside.
- Season the beef tenderloin generously with salt and pepper on all sides.
- Grill the beef tenderloin for 4-5 minutes per side or until the internal temperature reaches 130°F for medium-rare.
- Remove beef from the grill and allow it to rest for 10 minutes before slicing into 24 thin medallions.
- To prepare the Béarnaise, whisk egg yolks, tarragon vinegar, and minced shallots in a heatproof bowl over a pot of simmering water.
- Slowly drizzle the melted butter into the egg mixture while whisking vigorously until the sauce is thickened and emulsified.
- Remove from heat and stir in the fresh tarragon and lemon juice.
- Assemble each crostini by placing one beef medallion on a toasted baguette slice and topping with a dollop of warm Béarnaise sauce.
Best Ways to Enjoy It
Serve these beef tenderloin crostini on a large wooden board or silver platter. They look beautiful when arranged in neat rows for a party. Add a few extra sprigs of fresh tarragon for a pop of color. These are best served while the beef is still slightly warm.
Pair these appetizers with a crisp glass of red wine or sparkling cider. They are perfect for a fancy Christmas Eve or a cozy New Year’s party. Set the platter on the coffee table and let everyone dig in. Your guests will feel warm and welcomed in your home.
Storage & Reheating
These are best when assembled and eaten immediately for the best texture. If you have leftovers, store the beef and sauce in separate airtight containers. The beef will stay fresh in the fridge for up to three days. To reheat, gently warm the beef in a 300°F oven for five minutes.
Avoid reheating the Béarnaise sauce in the microwave or it may break. Instead, let it come to room temperature and whisk in a tiny splash of warm water. Assemble the crostini just before you are ready to snack again. This keeps the bread nice and crunchy for you.
Tips for Best Results
- Don’t skip resting the meat for at least ten minutes after grilling.
- Use a meat thermometer to ensure the beef reaches exactly 130°F.
- Avoid using a stale baguette; fresh bread provides the best crunch.
- Prepare the baguette slices a few hours early to save time.
- For Christmas, garnish with a tiny bit of red pomegranate seeds.
- Upgrade the flavor by using high-quality grass-fed butter for the sauce.
- Whisk the sauce constantly to prevent the eggs from scrambling.
- Slice the beef against the grain for the most tender bite.
Ways to Switch It Up
- Swap the baguette for gluten-free crackers to accommodate dietary needs.
- Use fresh thyme or rosemary if you cannot find fresh tarragon.
- Add a thin layer of horseradish cream for an extra spicy kick.
- Top with pickled red onions for a bright, seasonal winter garnish.
Common Questions
Can I make the sauce in a blender?
Yes, you can slowly drizzle the warm butter into the blender with the other ingredients. This is a great time-saver for busy holiday hosts. Just make sure the butter is hot enough to cook the yolks slightly.
How do I know when the beef is done?
A digital meat thermometer is your best friend for this recipe. Aim for 130°F for a perfect medium-rare center. The temperature will rise slightly as the meat rests on the counter.
Will kids enjoy these appetizers?
Most kids love steak and toasted bread, so these are usually a hit. You can leave the sauce off a few for picky eaters. They are the perfect size for little hands to grab and enjoy.
I hope these elegant little bites bring a touch of joy to your holiday celebrations. They are so simple to make but always leave a lasting impression on guests. Enjoy every delicious moment with your loved ones!
