Chermoula:
1 preserved lemon, flesh removed, skin roughly chopped
4 garlic cloves, chopped
1 cup chopped flat-leaf parsley
1 cup chopped cilantro
1 teaspoon saffron threads, soaked in 2 tablespoons hot water
1 teaspoon smoked paprika
1 teaspoon crushed red pepper flakes
1 teaspoon ground cumin
4 tablespoons olive oil
4 tablespoons lemon juice
Kosher salt and freshly ground black pepper
4 boneless skinless chicken breasts
Rice, for serving
Combine all chermoula ingredients in a food processor and process until the texture is like pesto. Pour over chicken breasts and refrigerate for 30 minutes.
Heat oven to 425F. Line a baking sheet with parchment or foil.
Lay chicken on prepared baking sheet and bake until the internal temperature reaches 165F, about 18 minutes. Let stand for 5 minutes before slicing. Serve with rice.
