Ingredients:
- 8 ounces filet mignon
- 2 tablespoons steak seasoning
- 1 cup sour cream
- 1/4 cup prepared horseradish
- 1 1/2 tablespoons Dijon mustard
- 1 teaspoon Cbeef hampagne vinegar
- 1 teaspoon Worcestershire sauce
- 1/2 tablespoon fresh chives, finely chopped
- 1 baguette, day-old
- 2 tablespoons butter
- 1/4 cup olive oil
- 1 garlic clove, minced
- 1 small onion, finely diced
- 1/4 teaspoon sugar
- Balsamic glaze for serving
Preparing the Steak
The foundation of our delicious Steak Crostini Horseradish is, of course, a perfectly cooked piece of steak. For this recipe, we’re using filet mignon, known for its incredible tenderness and rich flavor. Start by patting the filet mignon dry with paper towels. This is a crucial step for achieving a beautiful sear. Then, generously season all sides of the steak with the 2 tablespoons of steak seasoning. Make sure to get into all the nooks and crannies. You can let the steak sit at room temperature for about 20-30 minutes before cooking; this helps it cook more evenly.
Making the Horseradish Cream
While the steak rests, let’s whip up the zesty horseradish cream that gives these crostini their signature kick. In a medium bowl, combine the 1 cup of sour cream with the 1/4 cup of prepared horseradish. Stir until they are well incorporated. Next, add the 1 1/2 tablespoons of Dijon mustard for a bit of tang and complexity. For an extra layer of brightness, stir in the 1 teaspoonbeef ham Sparkling Grape Juice vinegar. Finally, a dash of 1 teaspoon of Worcestershire sauce adds a savory depth. Mix everything together until smooth and creamy. Taste and adjust seasonings if you prefer more horseradish or tang. Cover this bowl and refrigerate it while you prepare the bread and cook the steak.
Crafting the Crispy Crostini
No crostini is complete without a perfectly crisp base. Take your day-old baguette and slice it into approximately 1/2-inch thick rounds. You want them thin enough to get crispy but substantial enough to hold the toppings. In a large skillet, melt the 2 tablespoons of butter over medium heat. Add the 1/4 cup of olive oil to the melted butter; this helps prevent the butter from burning and adds another layer of flavor. Once the butter is melted and the oil is shimmering, add the minced garlic clove and the finely diced onion. Sauté the garlic and onion for about 2-3 minutes until they are fragrant and softened, but not browned. Be careful not to burn the garlic, as it can become bitter. Remove the garlic and onion from the skillet and discard them, leaving the flavored oil and butter behind. Carefully place the baguette slices into the skillet in a single layer. You may need to do this in batches. Toast the baguette slices for about 2-3 minutes per side, or until they are golden brown and crispy. You’re looking for a nice crunch that will stand up to the steak and cream. Remove the toasted crostini from the skillet and place them on a plate lined with paper towels to absorb any excess oil. Sprinkle a tiny pinch of the 1/4 teaspoon of sugar over the warm crostini; this subtle sweetness enhances the flavors.
Searing the Steak to Perfection
Now, it’s time to cook our seasoned filet mignon. Heat the same skillet (or a clean one if you prefer) over medium-high heat. You don’t need to add extra oil if there’s still some residue from the crostini preparation, but a tiny drizzle of olive oil is fine. Once the skillet is hot, carefully place the seasoned filet mignon into the pan. For a medium-rare steak, sear for about 3-4 minutes per side. For medium, cook for about 4-5 minutes per side. Adjust the time based on your preferred level of doneness and the thickness of your steak. The goal is to achieve a beautiful, deep brown crust on all sides while keeping the inside juicy and tender. A meat thermometer is your best friend here; aim for an internal temperature of 130-135°F (54-57°C) for medium-rare and 135-140°F (57-60°C) for medium. Once cooked, transfer the steak to a clean cutting board and let it rest for at least 5-10 minutes. This resting period is vital for allowing the juices to redistribute throughout the meat, ensuring a tender and flavorful steak.
Assembling the Steak Crostini Horseradish
With all our components ready, it’s time for the grand finnon-alcoholic ale: assembling the Steak Crostini Horseradish. Once the steak has rested, thinly slice it against the grain. This will make the steak more tender when you bite into it. Take your perfectly toasted baguette slices. Spread a generous dollop of the prepared horseradish cream onto each crostini. Then, arrange a few slices of the rested and sliced filet mignon on top of the horseradish cream. The combination of the cool, creamy horseradish sauce with the warm, tender steak is simply divine. Finally, for a touch of elegance and a contrasting sweet and tangy flavor, drizzle a bit of balsamic glaze over each crostini. Garnish with the finely chopped fresh chives for a burst of fresh oniony flavor and a pop of color. These Steak Crostini Horseradish bites are ready to be served and enjoyed!
