French Onion Chicken

Featured in Chicken.

Craving this dish because I love French onion soup but needed something more filling. Let onions get sweet and golden, then stacked them over spiced chicken. Tossed it with lots of yummy cheese and paired with cauliflower mash to lighten it up a bit. The chicken turned out juicy, cheese browned perfectly, and the whole family ended up wanting seconds. Definitely a keeper!

Incredible Gooey French Onion Chicken

I've transformed the classic flavors of French onion soup into something even tastier with this gooey delight. You won't miss the bread here - just juicy chicken covered in sweet, slow-cooked onions and melty cheese that'll make your mouth water. I pair it with a smooth cauliflower and potato blend that soaks up all the tasty juices.

What Makes This French Onion Chicken So Good

The best thing about this dish is how it takes soup flavors and turns them into a protein-rich meal that still feels like you're eating something totally indulgent. It's exactly what you need when it's cold outside and you want something warm and filling. It also warms up great the next day, making it perfect for busy nights when cooking isn't an option.

Finishing Touches

Frequently Asked Questions

→ Why mix cauliflower and potatoes?

It makes the mash feel lighter but still creamy. Plus, you’re sneaking in extra vitamins and flavor!

→ Can I swap the cheese types?

You sure can! Provolone or gruyere tastes amazing, but mozzarella or Swiss does the job perfectly fine too.

→ Why slice the chicken thinner?

Thinner pieces cook faster, leaving no overcooked spots, and hold more cheesy, oniony goodness on top.

→ What’s the perfect onion caramelization look like?

The onions need to be super soft and deep golden-brown. Let them cook longer for a better, sweeter flavor.

→ Can anything be prepped beforehand?

Absolutely! Get the onions caramelized ahead, then melt the cheesy topping on the chicken when you’re ready to serve.
