Ingredients

Scale

Horseradish Cream

½ cup sour cream
2 tablespoons horseradish
1½ tablespoons quality mayonnaise
1 teaspoon apple cider vinegar
½ teaspoon kosher salt
1 teaspoon Worcestershire sauce
2 tablespoons chives, minced
Freshly cracked black pepper, to taste

Crostini

1 ciabatta baguette, sliced into 12 ½-inch pieces
Olive oil
2 garlic cloves, halved

Steak

1 pound boneless ribeye steak (¾ inch thick), brought to room temperature 30 minutes before cooking
Kosher salt
3 tablespoons avocado oil
1½ tablespoons butter
2 garlic cloves
1 sprig rosemary

For Garnish

2 tablespoons chives, minced
Freshly cracked black pepper

Instructions

1. Make the Horseradish Cream

In a bowl, stir together all ingredients until smooth and well combined. Refrigerate until ready to use.

2. Prepare the Crostini

Preheat your oven on the Broil setting.
Slice the baguette and brush both sides with olive oil.
Arrange on a baking sheet and broil for 2 minutes per side, or until golden brown.
While warm, rub the top of each crostini with the cut side of the garlic cloves. Be sure to rub the edges too for added flavor. Set aside.

3. Cook the Steak

Pat the ribeye steak dry and season generously with kosher salt.
Heat a cast-iron skillet over high heat for 5 minutes, until smoking hot.
Add avocado oil and carefully place the steak in the pan.
Cook for 2 minutes per side, flipping until a golden crust forms. Repeat until the steak reaches 15°F below your desired internal temperature (see notes).
Add butter, garlic cloves, and rosemary. Place rosemary and garlic on top of the steak and baste with the butter by tilting the pan and spooning over the steak for 2 minutes.
Transfer the steak to a wire rack to rest for 6 minutes.

4. Assemble

Slice the steak into ½-inch slices.
Top each crostini with a slice of steak.
Add a small dollop of horseradish cream on top.
Garnish with chives and freshly cracked black pepper. Serve immediately.
