🧅 For the Caramelized Onions:

• 2 large yellow onions, thinly sliced

• 2 tbsp unsalted butter

• 1 tbsp olive oil

• 1/2 tsp salt

• 1/4 tsp black pepper

• 1 tsp fresh thyme (or 1/2 tsp dried thyme)

🍗 For the Chicken:

• 4 boneless, skinless chicken breasts

• 1 tsp garlic powder

• 1/2 tsp paprika

• Salt & pepper, to taste

• 1 cup shredded mozzarella or Gruyère cheese

• 1/2 cup shredded Parmesan cheese

👩‍🍳 Instructions

1. Caramelize the Onions

• In a large skillet, heat butter and olive oil over medium-low heat.

• Add sliced onions, salt, pepper, and thyme.

• Cook for 15–20 minutes, stirring occasionally, until golden and soft.

• Add balsamic vinegar (if using), stir, and cook 1–2 more minutes.

• Set aside to cool slightly.

2. Prepare the Chicken

• Butterfly each chicken breast by cutting a pocket in the side without slicing all the way through.

• Season the inside and outside with garlic powder, paprika, salt, and pepper.

3. Stuff the Chicken

• Stuff each pocket with a spoonful of caramelized onions and a mix of mozzarella and Parmesan cheese.

• Secure with toothpicks if needed to keep filling inside.

4. Sear the Chicken

• Preheat oven to 200°C (400°F).

• Heat olive oil in an oven-safe skillet over medium-high heat.

• Sear chicken breasts for 3–4 minutes per side, until nicely browned.

5. Bake

• Transfer the skillet to the preheated oven (or place chicken in a baking dish).

• Bake for 15–20 minutes, until the chicken is fully cooked (internal temp: 75°C / 165°F).
