Crostini with Beef and Chimichurri Sauce

Crostini with Beef and Chimichurri Sauce

Yield 12-14 crostini

Finger food doesn't get much better than this! Mouth-watering local steak, thinly sliced and topped with a creamy, herby, garlicky sauce, is served atop crunchy, toasted baguette slices for an appetizer that's effortlessly indulgent and delectable.


  • 1 lb. Peterson flank, sirloin, or tenderloin steak
  • ½ teaspoon kosher salt
  • ½ teaspoon fresh cracked black pepper
  • 1 Tablespoon olive oil
  • ½ cup créme fraîche
  • ½ teaspoon fresh garlic, finely minced
  • 1 teaspoon lemon zest
  • ¼ teaspoon kosher salt
  • 1 Tablespoon scallions (green parts only), finely minced
  • 12-14 slices crostini
  • ¼ cup chimichurri sauce
  • 2-3 Tablespoons microgreens


Preheat oven to 225°, pat steaks dry with paper towels, and season with salt and pepper. Place on a wire rack set in a rimmed baking sheet and place in oven. Cook until meat thermometer registers 120°, about 20-25 minutes.

Next, heat oil in a 12-inch skillet over medium-high heat until just smoking. Sear steaks, flipping every 1 minute, until a brown crust forms on both sides, about 4 minutes total. (Do not move steaks between flips.) Return steaks to the wire rack and let rest for 10 minutes.

Meanwhile, make the sauce: Combine créme fraîche, garlic, lemon zest, scallions, and kosher salt.

Move steaks to a cutting board and slice as thin as possible, going against the grain.

To assemble, arrange the crostini on a large, flat platter. Top each with a slice of steak, ½ teaspoon of chimichurri, and a dollop of sauce, then top with a few microgreens and serve.
