Description

A delicious stuffed chicken featuring caramelized onions and melty Gruyère cheese, perfect for family dinners or special occasions.


Ingredients

Scale
  • 2 tablespoons unsalted butter
  • 4 large onions, halved and thinly sliced
  • Salt and pepper, to taste
  • 2 teaspoons fresh chopped thyme, divided
  • 2 tablespoons balsamic vinegar (optional)
  • 2 cloves garlic, minced
  • ½ cup beef broth or stock, divided
  • 1 tablespoon olive oil
  • 4 boneless, skinless chicken breasts
  • 2 teaspoons garlic powder
  • 1 teaspoon ground thyme
  • 1 cup shredded Gruyère cheese
  • 4 tablespoons freshly grated Parmesan cheese

Instructions

  1. Preheat the oven to 400°F (200°C) and lightly grease a 9×12-inch baking dish with olive oil.
  2. Melt the butter in a large skillet over medium-high heat; add the onions, salt, pepper, and half the thyme. Cook until softened, about 5–8 minutes.
  3. Reduce heat to medium and continue cooking until onions are caramelized and jammy, approximately 15 minutes. Add ¼ cup of beef broth to deglaze if the pan gets dry.
  4. Stir in balsamic vinegar and cook for 1 minute before adding minced garlic; sauté for an additional minute until fragrant.
  5. Cut chicken breasts horizontally to create pockets; season inside and outside with salt, pepper, garlic powder, and ground thyme.
  6. Stuff each chicken breast with the caramelized onions, Gruyère, and Parmesan; seal with toothpicks.
  7. Transfer remaining onions to the prepared baking dish with the remaining beef broth and place the stuffed chicken on top.
  8. Sear the stuffed chicken in the skillet with olive oil for 4 minutes on each side until golden brown.
  9. Return chicken to the baking dish, spooning pan juices over the top, and sprinkle remaining thyme; bake for 15–20 minutes until chicken is fully cooked.
  10. Remove toothpicks and serve warm with the onions and juices.

Notes

For a crispier chicken skin, broil for 1-2 minutes at the end. Ensure chicken is sealed properly to prevent stuffing from spilling out.
