  • Garlic
  • Worcestershire Sauce

Ingredient notes and substitutions.

  • Alternate protein. - This rich caramelized onion sauce is so good on other meats like pork chops and even beef tenderloin. Feel free to add it to whatever meat you prefer
  • The best onions for caramelized onions are yellow onions. - They have a nice balance of sharp and sweet flavors that make the best-carmelized onions for this gluten-free french onion chicken.
  • Garlic - You can use fresh minced or garlic powder. If you are using fresh minced garlic, add it to the onions after they have caramelized, so you don't end up with burned garlic.
  • Worcestershire sauce. - Make sure you are using a gluten-free Worcestershire sauce. I use Lea and Perrins Worcestershire sauce which is gluten-free. If you can't find a gluten-free Worcestershire sauce, you can double the amount of gluten-free soy sauce.
  • Gluten-free soy sauce. - Make sure you are using a gluten-free soy sauce or tamari sauce. You can also use equal parts coconut aminos.
  • Arrowroot starch. - If you don't have arrowroot starch on hand, you can also use corn starch or potato starch instead.
  • Cheese - I find this gluten-free french onion chicken bake has the best flavor with a combination of provolone, parmesan, and gruyere cheeses. If you can't find gruyere cheese, you can sub in asiago. If you really want to, you can also use mozzarella, but it won't have as much flavor.

Tips for making the best caramelized onions.

Caramelized onions are not hard to make; they just take a little bit of time. In this gluten-free french onion chicken, they are really the star of the show. Here are a few tips to get them delicious every time.

  • Be sure to use both olive oil and butter that the recipe calls for. The balance of the two ingredients helps the onions caramelize without burning and adds more flavor.
  • Keep the heat on the lower side so the onions cook slowly.
  • The longer the onions cook, the more developed the sweetness that comes out of the onions as the sugars break down. This process could take twenty minutes or so, don't try and rush it. Trust me, you want the good flavors.

French onion chicken faq.

What is the best kind of chicken to use for french onion chicken?

I prefer to use boneless chicken breasts for this recipe. If you like dark meat, you can use boneless, skinless thighs. Just make sure whatever chicken you are using is fairly even. You don't want to use thin chicken, as it will tend to dry out while the cheese is melting.

Do you need an oven-safe skillet?

Having an oven-safe skillet makes this recipe easier, but it's unnecessary. You can transfer the chicken and sauce into a baking dish before topping it with cheese and placing it in the oven to melt. If you prefer it even easier, you can simply put a lid over your skillet to help melt the cheese. Just note the cheese won't be as golden.

More tips and tricks.

  • Don't overcook the chicken. - When you start the chicken, only worry about searing it. Don't worry about cooking it all the way through at this point; it will finish cooking once it's back in the sauce and placed in the oven to melt the cheeses.

Steps.

There are only a few simple steps that you need to do to make this gluten-free french onion chicken recipe.

  1. Sear the chicken.
  2. Caramelize the onions.
  3. Make the sauce.
  4. Add the cheese and bake to melt.

Serving suggestions.

My family loves this gluten-free french onion chicken bake served with simple creamy gluten-free mashed potatoes. It really is the perfect pairing. If you are like me and like to add vegetables to the family, I suggest something like my grilled asparagus, lemon broccoli, or even some roasted Brussels sprouts.

Making ahead.

While I wouldn't suggest making this recipe entirely ahead of time, there are some things you can do to make this recipe faster for the night you enjoy it.

  • Chicken - You can prep the chicken by ensuring equal thickness.
  • Onions - If you want to cut the cooking time down, you can caramelize the onions beforehand since this is the longest time needed for this recipe. Just store them in a container in the fridge until you are ready. Once you are making the rest of the recipe, warm the onions up in a skillet with olive oil and butter before making the sauce.
  • Sauce - You can take it one step further and make the complete sauce ahead of time. Then when you are ready to make the chicken, it is prepared to top and get into the oven to melt the cheeses.

Storing and reheating leftovers

If you have leftovers store them in an airtight container in the fridge for up to 3-4 days or in the freezer for up to three months.

  • To reheat in the microwave, heat it in thirty-second intervals until the chicken is warmed through.
  • If you prefer to reheat it in the oven, place it in an oven-safe baking dish and bake at 350 degrees for about fifteen minutes until the chicken is warm and the cheese is remelted.
