Skillet French Onion Chicken
Rich broth, sweet caramelized onions, bubbly melted cheese make French onion soup a comforting classic. Add French onion chicken to your weekly rotation and bring those flavors into a hearty, quick, easy meal that will warm you all the way through.
French onion soup is so decadent and rich that as much as I love it, a little cup is usually enough. But nobody in my house is going to let a little cup of anything pass for dinner.
Skillet French onion chicken lets me have the flavors I love in a chicken recipe that works as a main dish. The pan-seared chicken is moist and tender, and the dish is as easy to clean up as it is to make. Serve it with rice pilaf, oven roasted asparagus, and chocolate cake for dessert, and you have yourself a complete meal.
This is one of my all time favorite ways to make chicken. Last year I spent several weeks in France, and could not stop eating the “onion soup”.
Every little cafe I sat at, every restaurant, I would try the onion soup, and in my mind call it the “French onion soup” and just let it sit on my tongue. I would save that caramelized onion, rich nutty cheese, and deliciously flavored broth.
Then I would be hungry an hour later. Hahah.
Making this skillet chicken was the perfect compromise. All the delicious flavor, with a great protein base to help it carry me through a little longer.
The flavors are insane, especially since you deglaze the pan, and really take advantage of all the seared on brown bits, combined with the richly caramelized onions, and that cheese. Well you can see why it is my favorite.
What does it mean to “deglaze”?
Deglazing is the process of adding liquid to free the brown bits that get stuck to the bottom of the pan as you caramelize or sear meat and vegetables.
If you’re using a nonstick pan—especially a nice new one—you don’t get those brown bits, which is where the most intense flavor develops.
So for skillet French onion chicken, use a regular (non-nonstick) pan if you can or cast iron.
Here’s how to deglaze:
Slowly add broth, wine, water, or juice to the hot skillet (or baking dish, if you’re preparing something else) after the food you were browning has been removed.
Scrape and stir the browned bits from the bottom of the pan until they’re all loose, using a wooden spoon.
Continue cooking and stirring until they’re all melted into the liquid.
If the recipe directs, reduce or thicken the liquid.
What should I serve with French Onion Chicken?
Let’s not mince words: French onion chicken is rich.
The deeply browned onions, the beef broth, the cheese—finding the right side dish is important.
If it’s too starchy the whole meal will just be heavy. If it’s too mild the other flavors will overwhelm it. If it’s too sweet it’ll compete and neither flavor will work.
The right side dishes will be simple, clean flavors, and a dash of acid won’t hurt. Try these:
- Apple Spinach Salad with Balsamic Vinegar Dressing
- Escarole, Roasted Tomato and Wheat Berry Salad
- Roasted Vegetables
- Roasted Cauliflower
- Oven Roasted Broccoli
Can I use chicken thighs for French Onion Chicken?
Folks in lots of countries are baffled by the Americans’ taste for chicken breasts. They consider the white meat dry, preferring to use the dark meat of chicken legs and thighs.
So yes, in most chicken recipes you can just use the meat you prefer, and if chicken thighs are your preference, you can certainly use them for French onion chicken.
HOWEVER, chicken breasts lend themselves to pan seared chicken recipes better than softer thighs do, and with the rich cheese and the deeply flavored beef broth, the firm, mild meat of chicken breasts does seem to work better.
Besides, with this cooking method, dry is the last thing you will think about this chicken. It will be moist and delicious.
