French Onion Chicken Casserole Recipe

French Onion Chicken Casserole blends shredded cooked chicken with a creamy mixture of mayonnaise, sour cream, heavy cream, and beef bouillon, folded together with green beans and caramelized onions. Topped with Swiss cheese and biscuit quarters, baked until bubbly and browned, it offers a rich, layered dish combining creamy, savory, and crispy textures.

Description

This French Onion Chicken Casserole starts by mixing cooked shredded or cubed chicken with mayonnaise, sour cream, heavy cream, beef bouillon granules, salt, black pepper, and rubbed sage, creating a creamy and well-seasoned base. French cut green beans and caramelized onions are folded in to add vegetable texture and sweetness. The mixture is spread evenly in a greased baking dish and baked at 350°F for 30 minutes to meld the flavors and heat through.

After the initial baking, slices of Swiss cheese are layered over the hot mixture, followed by quartered refrigerated biscuits arranged evenly on top. The casserole returns to the oven for an additional 10 minutes until the biscuits are lightly browned and the cheese is melted, adding a crispy, cheesy crust to the creamy interior. After resting briefly, this dish is ready to serve.

The use of beef bouillon granules enhances the savory depth, balancing the richness of dairy and chicken. The biscuits on top introduce a soft but slightly crisp bread component that rounds out the dish.

Grinding bouillon cubes finely ensures even flavor distribution.
