French Onion Chicken is a hardy protein-rich version of French Onion Soup. It’s a great comfort food for weekends when you have a little more time to spend in the kitchen (caramelized onions – mmmmm!)
We have so many tasty flavorful chicken recipes that people love to make for busy weeknights such as our Chicken Enchilada Casserole or Slow Cooker Chicken Thighs. This chicken dish is one you might want to keep for the weekend since it requires more hands-on time, but it is well worth the effort. Note though, that you can caramelize the onions in the Instant Pot to save time, or you can do the onions the day before while you’re doing the dishes, so that this meal becomes quick enough for a weeknight.
French Onion Chicken is made with chicken breast and caramelized onions topped with melty gooey Gruyere cheese, crunchy croutons, and freshly chopped parsley. It’s the kind of dish that makes you come back for “just one more bite.”
What Kind Of Onions To Use
The most common onions used in many recipes are yellow onions. They have the perfect flavor for casseroles, soups, and stews. You can also use Vidalia onions, which is what I used for this recipe. They are a varietal in the sweet onion family. However, yellow or sweet onions of any variety will give the dish a great flavor.
How To Caramelize Onions
Caramelization cooking of onions takes time, but trust me, it is worth it. It adds an extra layer of flavor.
First, you’ll need to heat oil on the skillet, then add sliced onions. Cook the onion slices for a few minutes, stirring often but not all the time. We want the onion to become a little brown, but not burnt.
To caramelize onions you need to cook them slowly for about 30 minutes. Don’t rush! Onions need time to cook properly to caramelize those sugars. You can check out our article on how to caramelize onions for more tips to the perfect caramelized batch of onions. And don’t forget to check out how to caramelize them in the Instant Pot, which really saves time.
Tips For Making French Onion Chicken
After the onions are caramelized, you’ll toss cubed chicken breast in flour mixture and cook them for about 6-8 minutes until golden.
Then add beef broth and caramelized onions back to the skillet and cook until the sauce is reduced. Top it with Gruyere cheese and heat until melted and top with croutons just before serving.
