Ingredients
For the Crostini:
- 1 French baguette
- Olive oil, for brushing
- 2 cloves garlic, halved
For the Steak:
- 1 pound ribeye or sirloin steak
- Kosher salt and freshly ground black pepper
- 1 tablespoon olive oil
- 1 tablespoon unsalted butter
- 2 cloves garlic, smashed
- 2 sprigs fresh rosemary or thyme
For the Horseradish Cream Sauce:
- ½ cup sour cream
- 2 tablespoons prepared horseradish
- 1 teaspoon apple cider vinegar
- 1 tablespoon mayonnaise
- ½ teaspoon kosher salt
- 2 tablespoons fresh chives, minced
- Freshly ground black pepper, to taste
Instructions
-
Prepare the Horseradish Cream Sauce: In a bowl, combine sour cream, horseradish, apple cider vinegar, mayonnaise, salt, chives, and black pepper. Mix well and refrigerate until ready to use.
-
Prepare the Crostini: Preheat the oven to 375°F (190°C). Slice the baguette into ½-inch thick pieces. Arrange the slices on a baking sheet, brush both sides with olive oil, and bake for 7-10 minutes, flipping halfway through, until golden brown. While warm, rub each slice with the cut side of a garlic clove for added flavor.
-
Cook the Steak: Season the steak generously with salt and pepper. Heat a cast-iron skillet over high heat with olive oil until hot. Add the steak and sear for 2-3 minutes per side for medium-rare, adjusting time as needed for desired doneness. During the last minute of cooking, add butter, smashed garlic, and herbs to the pan. Tilt the pan slightly and spoon the melted butter over the steak to baste. Remove the steak from the skillet and let it rest for 5 minutes before slicing thinly against the grain.
-
Assemble the Crostini: Spread a thin layer of the horseradish cream sauce on each toasted baguette slice. Top with a slice of steak and garnish with additional chives or fresh herbs as desired.
Notes
-
Choosing the Steak: Opt for tender cuts like ribeye or sirloin for the best texture and flavor.
-
Resting the Steak: Allowing the steak to rest before slicing ensures the juices redistribute, resulting in a juicier bite.
-
Make-Ahead Tips: The horseradish cream sauce can be prepared up to two days in advance and stored in the refrigerator. The crostini can be toasted a few hours ahead and kept in an airtight container. Assemble just before serving to maintain optimal texture.
