Ingredients needed

  • Chicken breasts: You’ll need 4 boneless skinless chicken breasts. You could also use boneless skinless chicken thighs for even more flavor.
  • Seasoning: The chicken is seasoned with a simple mix of kosher salt, pepper, and dried herbs de Provence.
  • Flour: For dredging the chicken and sealing in moisture to make the chicken nice and juicy.
  • Olive oil: Needed for searing the chicken and caramelizing the onions.
  • Onions: The star of this dish! The onions are caramelized until rich, sweet, and golden brown.
  • Garlic: Pressed or minced garlic is cooked with the onions to add deep, complex flavor to the dish.
  • For the sauce: Chicken broth and coconut aminos make up the base of the sauce. Flour is combined with the coconut aminos to thicken the mixture.
  • Gruyere cheese: Classic in French onion recipes and has an incredible nutty and earthy flavor that joins so well with the savory sauce and sweetness from the caramelized onions.
  • Parsley: Fresh herbs, like parsley, adds a pop of freshness and color.

How to make this easy chicken breast recipe

  1. Season the chicken: Rub the chicken with salt, pepper, and herbs de Provence, then dredge into the flour to coat all sides.
  2. Sear the chicken: Heat half of the oil in a large pan over medium heat. Sear the chicken breast for 3-4 minutes per side, until golden. Set aside on a plate.
  1. Cook the onions and garlic: To the same heated skillet add the remaining oil. Cook the onions over medium heat, stirring occasionally, for 12-15 minutes, or until the onions are caramelized into a browned color. Over the last minute or so, stir in the garlic.
  1. Deglaze the pan: Once the onions are caramelized, add the chicken broth and deglaze the pan.
  2. Make the sauce: Preheat the oven to 400 degrees F. Meanwhile, in a small bowl, whisk the coconut aminos with the flour until there are no visible lumps.
  3. Cook the sauce: Once the sauce bubbles, stir in the amino-flour mixture. Allow the sauce to cook for 3-4 minutes, or until it starts to thicken.
  4. Bake to finish the chicken: Return the chicken to the pan and spoon over the sauce. Top with grated cheese and bake for 10-12 minutes, or until the chicken is cooked through and the cheese on top is melted. Garnish with minced fresh parsley and enjoy!

Expert Tips

  • So that all of the chicken cooks at the same rate, use chicken breasts that are similar in size.
  • Give the chicken space in the pan while searing it, so it will brown nicely and not steam.
  • Make this skillet recipe gluten-free by using an all-purpose gluten-free flour.
  • Chicken breasts can vary in size, so it’s best to use a meat thermometer to check for doneness; the temperature should read 160 to 165 degrees F. We recommend removing it from the oven at 160ºF because it will continue to cook in the pan, even after being removed from the heat.

Variations

  • Chicken: Instead of chicken breasts, chicken thighs will work great in this recipe.
  • Sauce: Coconut aminos have antioxidant, anti-inflammatory, and antimicrobial properties and provide a healthier alternative to soy sauce. However, you may swap this with soy sauce, if preferred.
  • Cheese: We love the taste of Gruyere cheese in this, but you can use American Swiss cheese or provolone instead.
  • Herbs: Adding a garnish of fresh herbs is optional. Feel free to omit or swap the parsley for fresh basil, chives, or thyme.
