Like a lot of French cuisine, French onion soup originated among French peasants. Because food was scarce during France’s feudal age, the peasants had to find ways to make common garden plants and animals edible. In fact, onion soup has been a popular meal for peasants dating back to the Roman era. It was this ancient soup preparation method that inspired the addition of croutons to French onion soup, and today restaurants all over the world serve it in this way. The version of this dish as we know it originated in France in the 18th century, and was popularized in the United States.

How To Caramelize Onions
- Saute the onions in butter until they’re transparent and soft. Slowly cooking the onions in butter ensures that they pack maximum flavor. They will brown and soften in the butter, losing the sharp edge to their uncooked flavor. The naturally occurring sugars in the onions will caramelize, resulting in a pleasant, mild sweetness.
- Use a beef stock, or broth, to build the base for your onion sauce. This will help prevent the onions for drying out as they cook, and bring a strong, beefy flavor to the sauce. Be sure to scrape up the brown bits of onion forming on the bottom of the pan as you go. This will intensify the flavor of your sauce.
- Add a little of balsamic vinegar, or sherry to the pan to deglaze it. This will help bring some complexity of flavor to the caramelized onions.
- Allow your onions to cool down before stuffing the chicken breasts with them. There should be some onions leftover in the pan for the sauce. You should add these to your baking dish, with beef stock, as this will create more sauce for you to bake your stuffed chicken breasts in. Remember that more sauce means more flavor!
Sides to Serve with Stuffed Chicken
If you want this to stay low-carb, you should use cauliflower. A nice buttery cauliflower mash, or roasted cauliflower would be a great start. Steamed vegetables, zoodles, or cauliflower rice are also fantastic alternatives.
How To Make French Onion Stuffed Chicken
You’ll want to use evenly sized chicken breasts. If they’re all different sizes, they will cook differently, and your stuffed chicken breasts will be unevenly cooked. Some might even risk drying out while the others are cooking! Using evenly sized breasts means even cooking.
To make the stuffing easier, you’ll want to create a pocket in your chicken. Do this by cutting horizontally into each chicken breast, carving a cavity into the breast for your onion filling to go into.
Season your chicken breasts for maximum flavor. A mixture of salt, pepper and dried thyme is a great start. If you have your own preferred chicken seasoning, feel free to use that! Be sure to generously rub both sides of the chicken breast as well as the interior of the pocket. This will make sure that your chicken’s delicious seasoning is a part of every mouthful!
When stuffing your chicken breasts, use one to two tablespoons of the caramelized onion, depending on the size of the individual breast. You don’t want to over-stuff the pocket as the stuffing will leak out.
For the cheese, use a relatively neutrally flavored cheese such as Gruyere or mozzarella. These cheeses have a low melting temperature and won’t overpower the subtler flavors of your chicken and onion sauce. A hint of parmesan will bring an Italian touch to this very French dish.
When cooking, sear your stuffed breasts until each side is golden-brown. This sear will help seal in the chicken’s delicious juices.
Once you’ve achieved the sear, transfer your breasts to a baking dish with more caramelized onions. This will add to the flavor of your dish. Top this mixture with thyme and some more of your onion sauce before baking.
You can secure your stuffed chicken breasts by sealing the “mouth” of your chicken pockets shut with toothpicks. This will help to keep the onion stuffing inside the chicken breasts rather than spilling out into the onion sauce. The sauce has enough onion in there already.
