The Best Roast Chicken
1 small chicken (about 3 V2 pounds), quartered by your butcher (or by you!!!)
10 garlic cloves, peeled and gently smashed with a knife
10 thyme sprigs
10 sage leaves on the stem (more than one leaf per stem is fine—great even)
2 tsp. Diamond Crystal kosher salt, plus more as needed
1 lemon, cut into as many thin slices as you can get, seeds picked out
3 T. mushroom powder
Freshly cracked black pepper
1/2 tsp. baking powder
6 medium shallots or 4 large shallots, peeled and cut into roughly V4-inch-thick slices
3 T. extra virgin olive oil
One 12-ounce container arugula
A small loaf of soft bread (such as focaccia or ciabatta), cut into about 1/2-inch dice (roughly 4 cups), tossed with oil and broiled a few minutes until there are spots of crisp
2 T. sherry vinegar, plus more to taste
Pat the chicken quarters dry. Gently pull back the skin on each piece while keeping it attached on one end, like you’re opening a steno pad. Use a sharp paring knife to cut 2 to 3 slits about 1 inch deep into the meat of each chicken piece. Stuff those slits with the garlic cloves and herb pieces (keep the long stems attached to easily pluck them out later). Distribute about 1/2 tsp. salt over each quarter and top. each with 1 to 2 lemon slices, depending on the size of the piece. Replace the skin to cover each piece of chicken. Pat the top of the skin dry again. In a small bowl, whisk or fork together the mushroom powder, a few pinches each of salt and pepper, and the baking powder. Rub about two-thirds of the mixture all over the chicken skin, sides, and bottoms. (Note: If your chicken pieces are small, you don’t need to use the whole rub; treat it like a dry rub on barbecued meat… you want a thin, dry layer, not a thick, caked-on one.) Let the chicken sit for at least 20 minutes or up to 1 hour. Heat the oven to 475 °F. Pat the chicken skin one final time. Sprinkle a bit more of the powder blend onto the skin. Add the sliced shallots and olive oil to a large cast-iron skillet and toss to combine. Top with a few lemon slices. Place the chicken pieces on top of the lemon. Roast for about 25 minutes, until the skin is super crackly and browned, then reduce the heat to 425 °F and finish cooking, 5 to 15 minutes for the breasts and 10 to 20 minutes for the thighs and legs. You’ll know the pieces are ready to pull when their juices run clear, but you can use an instant-read thermometer to check for 15 5 °F or cut into the meat if you’re unsure; when the breast pieces are done, remove them with tongs and set them aside. Meanwhile, put the arugula in a large salad bowl along with the diced bread. When all the chicken pieces are roasted, remove them to the platter. Pluck out as much of the herb matter as you can by the stem, but don’t drive yourself crazy; it won’t be unpleasant for diners to encounter. If any garlic fell out of the chicken while roasting, leave it in the skillet. Pluck out the lemon slices and transfer them to a cutting board, along with the slices from the pan. Set the skillet full of drippings and shallots over medium heat and bring to a simmer. Cook for 4 minutes, until a bit reduced. Add the vinegar and whisk to combine. Cut the heat. Roughly chop the lemon pieces and add them to the arugula and bread cubes. Taste the pan dressing and add more vinegar (or salt) if needed for a deep, acidic warm vinaigrette. Drizzle most of the dressing over the arugula and bread, reserving some to avoid a greasy salad. Toss. Taste and add more dressing or salt as needed. Serve the salad with the roasted chicken.
