  • Fire Up the Skillet

Pour a splash of olive oil into a large skillet and crank the heat to medium-high, letting it sizzle and get ready for some serious cooking action.

  • Sear to Perfection

Carefully place the seasoned chicken into the hot skillet, letting each side dance in the heat for about 45 minutes until it transforms into a beautiful golden-brown masterpiece. Once gloriously seared, gently transfer the chicken to a waiting plate.

Description

Succulent French onion chicken melds classic French bistro flavors with hearty comfort. Golden caramelized onions and melted gruyère cheese crown tender chicken breasts for a luxurious dinner experience.


Ingredients

Scale
  • 4 boneless, skinless chicken breasts
  • 2 large yellow onions, thinly sliced
  • 4 slices gruyere or swiss cheese (or provolone)
  • 1 ½ cups beef broth (500 ml)
  • 2 tbsps olive oil
  • 2 tbsps unsalted butter
  • ¼ cup grated parmesan cheese
  • 1 tbsp balsamic vinegar (or worcestershire sauce)
  • 1 tsp dried thyme
  • 1 tsp salt
  • ½ tsp salt
  • ½ tsp black pepper
  • ½ tsp garlic powder
  • ½ tsp sugar (optional, helps caramelization)
  • 1 tsp dijon mustard
  • 1 tsp cornstarch mixed with 1 tbsp water (for thickening)
  • 1 tbsp fresh parsley, chopped (for garnish)

Instructions

  1. Seasoning Preparation: Thoroughly massage chicken breasts with a harmonious blend of salt, black pepper, garlic powder, and dried thyme, creating a comprehensive flavor profile that envelops the entire meat surface.
  2. Skillet Preheating: Ignite olive oil in a generous skillet over medium-high flame, waiting until the oil radiates a lustrous sheen and releases an aromatic fragrance.
  3. Searing Performance: Strategically position seasoned chicken into the scorching skillet, allowing each side to transform into a caramelized golden masterpiece, developing a crisp exterior while maintaining succulent interior for roughly 3-4 minutes per side.
  4. Resting Phase: Elegantly transfer the perfectly seared chicken to a holding plate, preserving the concentrated pan drippings that will serve as a flavor foundation for subsequent culinary steps.

Notes

  • Seasoning Strategy: Ensure even and generous coating of spices by patting chicken dry before seasoning, which helps spices adhere better and promotes superior caramelization.
  • Heat Management: Use a heavy-bottomed skillet to distribute heat evenly and prevent burning, maintaining consistent medium-high temperature for ideal golden-brown crust.
  • Moisture Preservation: Allow chicken to rest after cooking to retain internal juices, preventing dryness and ensuring tender, succulent meat with maximum flavor retention.
  • Versatility Hack: Swap chicken breasts with thighs for a more budget-friendly option that offers richer flavor and stays more moist during cooking process.
