AP – In the market squares of Sicily and Calabria, street vendors baste thick swordfish chops with a bright blend of lemon juice and olive oil, grilling them over smoldering coals and filling the air with an alluring mix of char and sweet.
The simple, ancient combination is called salmoriglio, and it’s the primary way fish is served in southern Italy.
At Milk Street, we knew that chicken would shine with a similar treatment – a quick soak in a lemony marinade followed by a turn on the grill or in a high-heat oven, plus a finishing splash of more sauce.
For this oven-cooked version from our book, Milk Street Tuesday Nights, Mediterranean, which limits recipes to 45 minutes or less, we first make a fragrant base of grated lemon zest, garlic, oregano, salt and pepper.
We then use some to season bone-in chicken thighs and the rest as the foundation for the salmoriglio that sauces the finished chicken.
Rather than use the juice of fresh lemons in the sauce, we squeeze lemon halves that have been roasted with the chicken.
The oven heat mellows the acidity so the sauce has a subtle sweetness and a more restrained tartness.
A touch of honey helps brown the chicken under the broiler, and fresh oregano evokes the herbaceous aromas of those Sicilian squares.
– One tablespoon grated lemon zest, plus two lemons halved crosswise
– Two medium garlic cloves, finely grated
– One teaspoon dried oregano, crumbled
– Kosher salt and ground black pepper
– Five tablespoons extra-virgin olive oil, divided
– Three pounds bone-in, skin-on chicken thighs, trimmed and patted dry
– One tablespoon honey
– One bunch watercress, trimmed, or five-ounce container baby arugula
– One tablespoon finely chopped fresh oregano
Heat the oven to 475°F with a rack in the lower-middle position.
Grate one tablespoon zest from the lemons, then halve the lemons and trim off the pointed ends so the halves sit stably with cut sides facing up; set the lemon halves aside.
In a small bowl, stir together the zest, garlic, dried oregano, one teaspoon salt and half
Measure one tablespoon of the lemon-garlic mixture into a large bowl. Stir four tablespoons of oil into the remaining mixture; set aside.
To the large bowl, add the remaining one tablespoon oil, the honey, one teaspoon salt and half teaspoon pepper, then stir to combine. Using a sharp knife, cut parallel slashes about one inch apart all the way to the bone on both sides of each chicken thigh.
Add the thighs to the bowl and turn to coat on all sides, rubbing the seasoning mixture into the slashes.
Arrange the chicken skin up and the lemon halves cut sides up on a rimmed baking sheet. Roast until the chicken is beginning to brown and the thickest part reaches 165°F to 170°F, about 20 minutes. Leaving the chicken in the oven, turn on the broiler.
Continue to cook until the chicken is deep golden brown and the thickest part reaches about 175°F, about five minutes. Remove from the oven. Place the watercress on a serving platter, creating a bed for the chicken. Using tongs, place the chicken on top of the watercress.
Squeeze three tablespoons juice from one or two of the lemon halves, then stir the juice along with the fresh oregano into the lemon-garlic oil to make the salmoriglio. Drizzle the sauce over the chicken and serve with the remaining lemon halves for squeezing.
