If your chicken breast halves are large, halve them crosswise. Marinating the chicken keeps the meat moist and imparts extra flavor. Though the recipe says to keep the fried chicken warm, it's equally good served at room temperature. In fact, if you're making this entire menu using a single oven, you'll need to let the chicken stand at room temperature while the squash casserole bakes.
Cooks' note:
Chicken can marinate up to 1 day.
