French Onion Chicken

Featured in Easy Chicken Recipes.

Wanted French onion soup but needed something heartier so tried this chicken version. Let the onions cook down till they got super sweet then piled them on seasoned chicken with tons of cheese. Used mashed cauliflower and potatoes underneath to keep it lighter. The cheese got all bubbly and brown on top. My picky eater cleared his plate which never happens. All the cozy flavors of the soup but filling enough for dinner.```

The Most Amazing French Onion Chicken Recipe

I took everything we love about French onion soup and turned it into something even better with this French onion chicken. Instead of bread you get perfectly juicy chicken smothered in sweet caramelized onions and gooey melted cheese. I serve it with a creamy cauliflower potato mash that soaks up all those amazing flavors.

Frequently Asked Questions

→ Why combine cauliflower with potatoes?

Adding cauliflower lightens up traditional mashed potatoes while keeping the creamy texture and adding nutrients.

→ Can I use different cheeses?

While provolone and gruyere are traditional, any good melting cheese will work. Swiss or mozzarella are good alternatives.

→ Why cut the chicken in half?

Thinner pieces cook more quickly and evenly, and provide more surface area for the onions and cheese.

→ How do I know when my onions are caramelized enough?

They should be golden brown and very soft. While 20 minutes works, longer cooking develops even more flavor.

→ Can I make this ahead?

You can caramelize the onions ahead of time. Complete final assembly and cheese melting just before serving.
