This is a true one-pot French-Italian dish — kind of like chicken fricassée, but with an Italian pasta sauce. It pairs perfectly with a side of pasta or a nice glass of wine. There are several delicious riffs one can add to this dish, and I encourage you to find your own, whether it’s sliced olives (my preference), a squeeze of lemon juice or a sprinkle of zest, fresh herbs, a splash of vinegar, a shower of Pecorino Romano, capers, or even chili crisp. Chicken Marengo is quite versatile, and in that sense it’s an ever-evolving dish.
