Go-to ingredients get a makeover in this low-lift dinner. Inspired by Greek lemon potatoes, in this recipe chicken thighs are roasted to a crisp, leaching schmaltz and blessing the potatoes with flavor and shine as they cook. The end result is a rich, sticky meal that needs nothing more than a green salad alongside. Saving the lemon juice for the end guarantees a never-bitter hit of much-needed brightness. To switch things up a little, use crushed dried rosemary in place of the oregano, or quartered Yukon Gold potatoes in place of the fingerlings.
