Ingredients

  • 4 boneless, skinless chicken breasts
  • 2 tablespoons olive oil
  • 2 large onions, thinly sliced
  • 2 cloves garlic, minced
  • 1 teaspoon thyme (fresh or dried)
  • 1 tablespoon balsamic vinegar
  • Salt and pepper, to taste
  • 1 cup Swiss cheese, shredded (or Gruyère)
  • 1/2 cup cream cheese, softened
  • 1/4 cup breadcrumbs (optional, for topping)
  • Fresh parsley (for garnish, optional)

Instructions

  1. Step 1: In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the sliced onions and cook, stirring frequently, for about 15–20 minutes until golden brown and caramelized. Add the minced garlic, thyme, balsamic vinegar, salt, and pepper, and cook for an additional 2–3 minutes. Remove from heat and let cool slightly.
  2. Step 2: Preheat your oven to 375°F (190°C). Slice a pocket into each chicken breast, being careful not to cut all the way through.
  3. Step 3: In a bowl, combine the caramelized onion mixture with the shredded Swiss cheese and softened cream cheese until well mixed. Spoon the filling into each chicken breast pocket, securing with toothpicks if necessary.
  4. Step 4: In the same skillet, heat the remaining tablespoon of olive oil over medium-high heat. Add the stuffed chicken breasts and sear for 3–4 minutes on each side until golden brown. Transfer the chicken to a baking dish and sprinkle breadcrumbs on top if desired. Bake in the preheated oven for 20–25 minutes, until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
  5. Step 5: Remove toothpicks if used and garnish with fresh parsley before serving.

Tips & Variations

  • For extra flavor, try using Gruyère cheese instead of Swiss for a nuttier taste.
  • If you prefer a crispy topping, add the breadcrumbs before baking to create a golden crust.
  • Make sure the chicken pockets are deep enough to hold the filling without tearing.
  • Serve with a simple green salad or roasted vegetables to balance the richness of the dish.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven to maintain moisture and flavor. Avoid overheating to keep the chicken tender.

How to Serve

The image shows four pieces of golden-brown grilled chicken breasts, each stuffed with a white melted cheese layer visible through a slit in the center. The chicken has a slightly charred texture with herb specks on top, giving a crispy and seasoned look. Beneath the chicken, there is a layer of cooked translucent caramelized onions with a light brown shine, pooling some clear sauce around them. Fresh green parsley leaves are sprinkled over the chicken and onions for added color contrast, all placed on a white plate. The plate sits on a white marbled surface, and the focus is sharp on the front chicken piece with soft background blur. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make this recipe ahead of time?

Yes, you can prepare the stuffed chicken breasts in advance and keep them refrigerated until ready to cook. Sear and bake them just before serving for the best texture.

What can I substitute if I don’t have Swiss cheese?

Gruyère or mozzarella work well as substitutes. Choose cheeses that melt nicely and complement the caramelized onion flavor.

Ingredients

Scale

Chicken

  • 4 boneless, skinless chicken breasts
  • 2 tablespoons olive oil, divided
  • 1/4 cup breadcrumbs (optional, for topping)
  • Fresh parsley (for garnish, optional)

Stuffing

  • 2 large onions, thinly sliced
  • 2 cloves garlic, minced
  • 1 teaspoon thyme (fresh or dried)
  • 1 tablespoon balsamic vinegar
  • Salt and pepper, to taste
  • 1 cup Swiss cheese, shredded (or Gruyère)
  • 1/2 cup cream cheese, softened

Instructions

  1. Prepare the Onions: In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the thinly sliced onions and cook, stirring frequently, for about 15 to 20 minutes until they are golden brown and caramelized. Add minced garlic, thyme, balsamic vinegar, salt, and pepper, then cook for an additional 2 to 3 minutes. Remove from heat and allow the mixture to cool slightly.
  2. Prepare the Chicken: Preheat your oven to 375°F (190°C). Slice a pocket into each chicken breast carefully without cutting all the way through, creating space for the stuffing.
  3. Stuff the Chicken: In a bowl, thoroughly combine the caramelized onion mixture with shredded Swiss cheese and softened cream cheese. Spoon this filling evenly into each chicken breast pocket, securing with toothpicks if necessary to keep the filling inside.
  4. Cook the Chicken: Using the same skillet, heat the remaining tablespoon of olive oil over medium-high heat. Sear each stuffed chicken breast for 3 to 4 minutes on each side until they develop a golden brown crust. Transfer the seared chicken breasts to a baking dish. If desired, sprinkle breadcrumbs on top for a crunchy topping. Bake in the preheated oven for 20 to 25 minutes until the chicken is fully cooked through and reaches an internal temperature of 165°F (74°C).
  5. Serve: Remove toothpicks if used, garnish with fresh parsley for a pop of color and freshness, and serve immediately while hot.

Notes

  • To ensure even cooking, pound the chicken breasts to an even thickness before slicing the pocket.
  • For a gluten-free option, omit the breadcrumbs or use gluten-free breadcrumbs.
  • Gruyère cheese can be used as a substitute for Swiss cheese for a slightly nuttier flavor.
  • Allow the caramelized onion mixture to cool before mixing with the cheeses to prevent melting.
  • Use a meat thermometer to check internal temperature for perfectly cooked chicken.
