Step 1

Preheat the oven: Preheat the oven to 400˚F.

Step 2

Trim and season the chicken thighs: With scissors or a sharp knife, cut off excess flaps of skin and fat from the thighs. Sprinkle with salt and pepper on both sides.

Step 3

Prep the chard stalks and leaves: Tear or cut the stalks from the leaves. Cut the stalks into 1-inch pieces. Slice the leaves into 2-inch-wide strips. Keep the stalks and leaves separate.

Step 4

Brown the chicken and par-cook the potatoes and carrots: In a large (12- to 13-inch) ovenproof skillet set over medium-high heat, add the oil. Once the oil shimmers, add the chicken with the skin side down. Cook on the skin side only for about 5 minutes without disturbing it, or until the skin lightly browns.Transfer to a plate. (If the chicken doesn’t fit in one skillet, cook in batches or use two smaller skillets and divide the ingredients between them.)Add the potatoes and carrots to the skillet and cook for 5 minutes, or until they brown lightly. 5 Prep the braising liquid: In a bowl or measuring cup, whisk the chicken stock, mustard, and lemon zest to combine.

Step 5

Braise the chicken: Add the chard stalks, smashed garlic and braising liquid to the skillet with the vegetables. Set the chicken pieces on top and sprinkle with the thyme.

Step 6

Transfer to the oven: Transfer the pan to the oven. Roast, uncovered, for 30 minutes, or until the chicken is cooked through and the vegetables are tender. Remove the pan from the oven.

Step 7

Add the chard leaves: Transfer the chicken thighs to a plate. Taste the broth and add more salt, if you like. Set the skillet over high heat and bring the liquid to a boil. Stir the chard leaves into the skillet and cook for 2 to 3 minutes, or just until wilted. Remove the garlic cloves.

Step 8

Serve: Set the chicken on top of the vegetables. Squeeze the lemon over the chicken and sprinkle with the parsley. Serve from the skillet, or transfer to a large serving platter. Serve as is, or with a salad.
