At Beverly Hills's celebrated steak house, Cut, chef Lee Hefter (a Food & Wine Magazine Best New Chef 1998) makes his over-the-top tartare with a mix of filet mignon and wagyu beef. The version here uses just prime beef tenderloin.
1/2 pound best-quality beef tenderloin, cut into 1/4-inch dice
2 tablespoons extra-virgin olive oil, plus more for drizzling
2 teaspoons Dijon mustard, plus more for serving
1 teaspoon Worcestershire sauce
11/2 tablespoons capers, coarsely chopped
4 tablespoons finely chopped red onion
Crostini, for serving
In a bowl, mix 1/4 cup of the mayonnaise, 1 teaspoon of the parsley and the tarragon. Season with salt and pepper and refrigerate.
In a medium bowl, mix the meat with the 2 tablespoons of olive oil, the remaining 1 teaspoon mayonnaise, the mustard, Worcestershire sauce and capers. Season with salt and pepper. Transfer to a cutting board and finely chop the meat.
Transfer the tartare to cold plates. Season with salt and pepper. Sprinkle with the chopped onion and the remaining parsley. Drizzle with olive oil and serve with the herb mayonnaise, mustard and crostini.
