I first made this French Onion Chicken Bake on a chilly, rainy Sunday when all I wanted was the deep, savory comfort of a steaming bowl of French onion soup, but in a hearty main dish form. As it baked, my entire house filled with the most incredible aroma: the scent of toasting onions, roasting garlic, and savory herbs that felt like a warm hug. When I pulled the dish from the oven, the chicken was glistening with a golden, flavorful crust, and the juices below had mingled to create a rich, oniony gravy. That first forkful, tender chicken infused with all those classic soup flavors, was an absolute revelation of cozy, effortless comfort food.

It’s the ultimate set-it-and-forget-it meal that tastes like you spent hours in the kitchen.
Ingredients
- 2-1/2 pounds chicken breasts (I prefer boneless, skin-on for maximum flavor and ease, but boneless/skinless or bone-in work)

- 1 (1 ounce) envelope dry onion soup mix (like Lipton)
