Tips for the Perfect French Onion Chicken Skillet

To ensure your French Onion Chicken Skillet turns out perfectly, consider these helpful tips:

  • Cheese Selection: Opt for high-quality Swiss cheese for the best melting and flavor. Gruyère is another excellent choice if you want to experiment.
  • Chicken Options: You can use either chicken breasts or thighs, depending on your preference. Dark meat (thighs) tends to be more flavorful and forgiving if slightly overcooked.
  • Serving Suggestions: This dish pairs wonderfully with mashed potatoes, steamed vegetables, or a simple green salad.
  • Balsamic Vinegar: Be cautious not to burn the balsamic vinegar when caramelizing the onions; it should darken but not turn black.
  • Adjust Seasoning: Taste the gravy before adding the chicken and adjust the seasoning if needed.

French Onion Chicken Skillet

Serves: 5 Prep Time: Cooking Time:
Nutrition facts: 200 calories 20 grams fat


  • 2 pounds Vidalia onions, sliced
  • 2 pounds boneless, skinless chicken breasts or thighs
  • 2 cups beef broth
  • 1 cup Swiss cheese, grated
  • 1/3 cup extra-virgin olive oil, divided
  • 2 tablespoons all-purpose flour
  • 2 teaspoons balsamic vinegar
  • 1/2 teaspoon dried thyme
  • 1/2 teaspoon dried sage
  • Kosher salt and freshly ground pepper, to taste


Step 1: Caramelize the Onions

Preheat your oven to 350º F.

Heat 2 tablespoons of olive oil in a large, oven-proof pan or skillet over medium heat.

Add the sliced onions, season with salt, and cook for 15-20 minutes, or until they become soft and caramelized.

Stir in the balsamic vinegar and continue cooking for another 3-5 minutes, allowing the onions to darken without burning.

Remove the caramelized onions from the heat and transfer them to a medium bowl.

Step 2: Sear the Chicken

In the same skillet, heat the remaining olive oil over medium-high heat.

Season the chicken breasts (or thighs) with salt, freshly ground pepper, dried thyme, and dried sage.

Place the seasoned chicken in the skillet and sear it on both sides until it turns a beautiful golden brown.

Once seared, remove the chicken from the skillet and set it aside.

Step 3: Create the Beef Gravy

Pour the beef broth into the skillet and bring the mixture to a boil, scraping up any flavorful bits stuck to the bottom of the pan.

Reduce the heat to medium-low and whisk in the all-purpose flour, stirring until the mixture thickens. Cook for 5-7 minutes until it reaches a smooth and thick consistency. Adjust the seasoning if necessary.

Step 4: Combine and Bake

Return the seared chicken and caramelized onions to the skillet. Stir everything together in the beef gravy.

Top the skillet with the grated Swiss cheese, creating a generous layer.

Transfer the skillet to your preheated oven and bake until the cheese is perfectly melted and bubbly, and the chicken is cooked through.
