The best One-Pan Cheesy French Onion Chicken Skillet delivers all the joy of French onion soup without the hassle or long hours. With the addition of tender chicken, it’s packed with protein, making it a family-friendly dinner that even picky eaters will love.
This French onion chicken recipe is a spin-off of our beloved French Onion Soup recipe, inspired by the cozy flavors we fell in love with last year. After craving it for weeks, Cade suggested turning it into something new, and voilà—French onion chicken was born!
It’s the same comforting flavors, simplified, and served with chicken. Serve it on its own, over rich and creamy mashed potatoes, or alongside a fiber-packed veggie like roasted green beans, brussels sprouts, or broccoli for a well-rounded meal.
Ingredients for French Onion Chicken
The ingredients for this dish are straightforward and likely already in your kitchen! Here’s what you’ll need:
For the Onions
- Butter – you can also use olive oil if you prefer

- Brown Sugar – used for caramelization
- Garlic – flavor baby!
- Fresh Thyme – I love the pop of fresh herbs in caramelized onions!
For the Dish
- Chicken Breasts – you could also use chicken thighs or tenders

- Beef Broth – base of the sauce for simmering the chicken
- Chicken Broth – the other half of the base for simmering the chicken
- Worcestershire Sauce – flavor, richness
- Bay Leaf – flavor, will be discarded after simmering
