Ingredients

Scale

Protein:

  • 1.5 pounds chicken cutlets or breasts (trimmed of visible fat and skin)
  • 1 cup Swiss cheese or Gruyere cheese (shredded)

Vegetables and Aromatics:

  • 4 large onions (thinly sliced)
  • 4 cloves garlic (finely minced)
  • 1 teaspoon dried thyme
  • 1 teaspoon fresh thyme

Liquids and Seasonings:

  • 2 tablespoons butter
  • 2 tablespoons olive oil
  • 2 cups low-sodium chicken broth
  • 2 tablespoons Dijon mustard or ground mustard
  • 1 pinch or 2 of brown sugar
  • sea salt or kosher salt
  • fresh black pepper
  • Cooked couscous, rice, quinoa, mashed potatoes, or egg noodles for serving

Instructions

  1. Melt of butter in a large heavy-bottomed oven-proof skillet over medium-low heat. Add of oil and incorporate finely chopped onions, seasoning lightly with salt, black pepper, and a pinch of granulated sugar.
  2. Slowly caramelize the onions for 50-55 minutes, stirring consistently to prevent burning and ensuring they transform into a rich, deep golden-brown color. Add additional butter if the onions start to stick or dry out.
  3. Once onions reach a luxurious caramel color, introduce minced garlic and dried thyme. Sauté the mixture for 1-2 minutes until the garlic releases its aromatic fragrance throughout the kitchen.
  4. Pour of chicken broth into the skillet, using a wooden spoon to scrape any flavorful browned bits from the bottom of the pan. Whisk in of Dijon mustard and adjust seasoning with salt and black pepper.
  5. Nestle chicken cutlets or breasts directly into the sauce, ensuring they are partially submerged. Cover the skillet tightly and simmer for 15-30 minutes, depending on the cut’s thickness, until the internal temperature reaches 165 degrees Fahrenheit (74 degrees Celsius).
  6. Position the oven rack approximately 6 inches from the broiler element and preheat to high. Sprinkle fresh thyme leaves over the chicken and generously top with grated Gruyère or Swiss cheese.
  7. Broil the chicken for 2-3 minutes, watching carefully to prevent burning, until the cheese melts and develops golden-brown crispy edges.
  8. Remove from the oven and let rest for 3-4 minutes. Serve immediately over couscous, rice, mashed potatoes, quinoa, or egg noodles, accompanied by crusty bread to soak up the rich, savory sauce.

Notes

  • Caramelizing onions takes patience, transforming them from sharp and crunchy to sweet and mellow with a deep golden-brown color that becomes the flavor foundation of this dish.
  • Layering seasonings like salt, pepper, sugar, garlic, and thyme creates complex taste profiles that elevate the chicken from ordinary to extraordinary.
  • Choosing the right skillet matters tremendously, with heavy-bottomed cast iron or stainless steel ensuring even heat distribution and perfect caramelization without burning.
  • Cooking times vary based on chicken cut thickness, so using a meat thermometer guarantees juicy, perfectly cooked protein without dry or undercooked sections.
  • Broiling cheese on top adds a crispy, golden-brown finish that transforms the dish into a restaurant-quality meal with minimal extra effort.
  • Serving over starchy sides like couscous or mashed potatoes helps soak up the rich, savory sauce, making every bite a comforting culinary experience.
