Sear the Steak

Bring the steaks to room temperature for 30-60 minutes. Then, pat each side dry with paper towels. Season all sides of the steaks with a generous amount of Kosher salt and freshly-ground black pepper.

Coat the bottom of a cast iron skillet with the neutral oil and heat it over high. Once the oil is shimmering and searing hot, carefully place both steaks in the pan, leaving some room between them. Don't move the steaks around! Let them sear so they have a nice brown crust, about 3 minutes.

Flip the steaks and sear for another 2-3 minutes. During the last minute of cooking, add the butter, thyme, and rosemary. Use a spoon to baste the steaks with the melted herb butter until the steaks reach an internal temperature of 130-135°F (54-57°C).

Set the steaks on a plate and let them rest for 5-10 minutes. Then, thinly slice the steaks into strips.

Make the Garlic Sauce

In a small bowl, combine the mayonnaise, sour cream, garlic, lemon juice, salt, and pepper. Whisk until the sauce is smooth. Add more salt and pepper, to taste. Set aside.

Assemble the Crostini

Place the crostini on a sheet pan. Sprinkle each toast with about 2 teaspoons of blue cheese crumbles. Broil on HIGH for 1-2 minutes, just until the blue cheese is warmed through but not completely melted.

Top each crostini with a slice of steak and a dollop of garlic sauce. Garnish the crostini with fresh chives and black pepper. Enjoy!

Tips & Tricks (5)

Slice Against the Grain 🔪
Cut the cooled steak against the grain into thin strips for maximum tenderness and easier bites on the delicate crostini without overpowering the bread.
Room Temperature Steak 🌡️
Remove the sirloin from the refrigerator 30 minutes before cooking to ensure even searing and a perfectly cooked interior throughout.
Emulsify Your Sauce Cold 🧊
Mix the sour cream, mayo, and blue cheese in a chilled bowl before adding garlic to prevent the sauce from breaking and maintain a luxurious, creamy texture.
Pat Dry for Maximum Crust 🧻
Use paper towels to thoroughly dry the steak surface before seasoning; moisture prevents browning and creates a superior crust for superior flavor.
Toast Crostini in Garlic Butter 🧈
Brush crostini with garlic-infused butter and toast until golden just before serving to add depth of flavor and prevent sogginess when topped with the steak.
