What to serve with French onion chicken
With a versatile chicken skillet dinner like this one, options for sides are pretty limitless.
Make a veggie that your family likes. Steamed broccoli, green beans, or carrots are great choices, as are starches like rice or potatoes.
Oh, and of course, a crusty loaf of French bread would be perfect with a comfort food meal like this French onion chicken, too.
Worst comes to worst, you can always do some frozen fries on the side, or some sweet potato tater tots as I like to do occasionally. A salad also pairs really nicely with this dish and keeps it low carb.
Frequently Asked Questions
I use yellow onions to make this dish because it’s what is in most versions of French onion soup. That being said, if you want to alter the flavour a bit and get creative, you can use other types of onions. Sweet onions such as Walla Walla and Vidalia are fantastic for caramelizing. The extra sugars in them will make them less bitter. If you want something a little milder, try a white onion. It will also be sweeter than the yellow onions. Red onions will give your dish a splash of bright color and a sweet mild flavor. While shallots are small, and they roast well because the layers are so thin. They have a garlicky taste. Leeks are great in sauces because their flavor mellows as they are cooked.
The healthiest option for protein is chicken breast. It has slightly less cholesterol and much less saturated fat than chicken thighs and legs. In a dish like this, boneless breast meat cooks more quickly because there is no bone in the meat. You can use chicken breast cutlets that are pre-cut for you at the store to make the recipe quicker, but you can always slice one chicken breast in half lengthwise to accomplish this.
The cheese that is best served with French onion soup or French onion chicken is DEFINITELY a nice Swiss cheese. I usually use the Jarlsberg brand, and Emmental is another delicious, mild cheese that would pair nicely with this chicken dinner. You ideally want a cheese that melts nicely and is relatively mild to highlight the gravy and onions.
You could also use pizza mozzarella if you're in a pinch!
When you make caramelized onions, you want to take your time. Keep in mind, you aren’t just browning them; you want the sugars in the onions to break down. The goal is for them to develop a perfectly deep, sweet flavour, not the taste of slightly burnt onions. Cut the onions fairly thin, but not too thin. If they are too thin, the will get crispy instead of caramelizing. Fry the onions in oil, not butter, and make sure to caramelize them over low heat, stirring once every few minutes. If you start to get a burnt spot, add some water and scrape it up, but continue cooking at a lower temperature.
Storing and reheating
You can store this meal in the refrigerator for up to 5 days, which makes it great for meal prep. You can make the dish in advance for a weeknight dinner, or even make a large batch to divide into single serving sizes. Then you will have lunches for several days, ready to go.
To reheat, microwave it for a few minutes, or pop it in the oven for 20 minutes at 350° Fahrenheit.
Freezing this recipe
Unlike French onion soup that loses its signature texture when frozen, this meal freezes beautifully and can be frozen for up to 3 months. That is why it's so perfect for meal prep dinners; you just need some meal prep containers and you're good to go!
As another option, you can freeze just the caramelized onions. Since they take a while to make, you can cook up a larger batch and freeze. Caramelized onions last in the freezer for at least 5 months.
The amazing caramelized onions make a great topping for any type of meat, soup, burgers and more! You can freeze them in small portions in a muffin tray for individual servings to spice up another meal.
