French Onion Chicken Skillet (Printable)

Chicken breasts with caramelized onions and melted cheese in a flavorful skillet creation.

# What You'll Need:

→ Chicken

01 - 4 boneless, skinless chicken breasts
02 - 1 teaspoon kosher salt
03 - 1/2 teaspoon freshly ground black pepper
04 - 1 teaspoon dried thyme
05 - 2 tablespoons olive oil

→ Onions

06 - 3 large yellow onions, thinly sliced
07 - 2 tablespoons unsalted butter
08 - 1/2 teaspoon sugar

→ Sauce

09 - 2 teaspoons minced garlic
10 - 1/2 cup dry white wine or chicken broth
11 - 1 cup low-sodium beef broth
12 - 1 tablespoon Worcestershire sauce

→ Topping

13 - 1 cup shredded Gruyère or Swiss cheese
14 - 1 tablespoon chopped fresh parsley (optional)

# Directions:

01 - Sprinkle chicken breasts on both sides with kosher salt, black pepper, and thyme.
02 - In a large skillet over medium-high heat, warm olive oil. Sear chicken for 3 to 4 minutes per side until golden. Transfer chicken to a plate and set aside.
03 - Reduce the skillet heat to medium. Melt butter, add the sliced onions and sugar. Cook, stirring frequently, until onions are deeply caramelized and golden, approximately 15 to 20 minutes.
04 - Stir in minced garlic and cook for 1 minute until fragrant.
05 - Pour in white wine or chicken broth, scraping up the browned bits from the skillet bottom. Simmer for 2 to 3 minutes to reduce slightly.
06 - Add beef broth and Worcestershire sauce. Return chicken breasts to the skillet, nestling them in the onions and sauce.
07 - Cover skillet and simmer on low for 10 to 12 minutes, until chicken is fully cooked with an internal temperature of 165°F.
08 - Uncover and evenly sprinkle Gruyère cheese over the chicken. Cover again and cook for 2 to 3 minutes until the cheese is melted.
09 - Finish with fresh chopped parsley if desired and serve immediately while hot.
