Adapted from the Barefoot Contessa's Foolproof If you feel like getting ahead, you can marinate the chicken in the mustard and buttermilk overnight or for a few hours; if you don't have time, don't worry. I made this for my in-laws without marinating the chicken at all, and they raved. If you marinate the chicken, too, the buttermilk definitely acts as a tenderizer. You can use any combination of bone-in, skin-on thighs or drumsticks. I love using thighs with this recipe. A few changes from the original recipe: You can find the original recipe online in various places, but these are the basic changes I've made: fresh bread crumbs versus panko; 4 tablespoons olive oil versus 2 tablespoons olive oil + 2 tablespoons butter; buttermilk versus white wine (because the buttermilk is thicker than wine, I find the breadcrumbs stick to it better); 4 thighs and 4 drumsticks versus 1 chicken cut into 8 pieces; oven temp at 400ºF the entire time. If you are up for a little adventure... ... this is what I suggest: Buy two chickens. Cut them up (video guidance here). Use the 4 thighs and 4 drumsticks here. Remove the breasts from the bones and make these tarragon chicken breasts on a subsequent evening. With the wings, necks, backbones, and breast bones, make stock. After two hours of gentle simmering, pull the meat from the stock bones, and make a simple chicken salad: mayonnaise + relish + a squeeze of lemon. Return the bones to the pot and gently simmer for another hour.
