  • 2 tablespoons kosher salt
  • 1 tablespoon whole black peppercorns
  • 1 teaspoon marjoram or oregano leaves

Cooking Instructions

  1. 1.

    Pulse mushrooms, kosher salt, peppercorns, and marjoram in a spice mill or mini food processor until coarsely ground. Pat meat dry, then rub mushroom mixture all over. Transfer to a wire rack set inside a rimmed baking sheet. Let sit at room temperature 1 hour (for even more flavor, chill, uncovered, overnight, then let sit at room temperature 1 hour before roasting).
