Prepare The Chicken Breast

Start by making a slit in the middle of each chicken breast. make a deep enough pocket for the stuffing, ensuring you do not cut it all the way through.

Once the onion is golden brown and caramelized, transfer them to a plate and set aside.

Stuff The Chicken Breast

Brown The Chicken Breast

Heat the same skillet where you cooked the onion, then add the olive oil.

Add the stuffed chicken breast and cook them for 3 minutes on each side until golden brown.

Turn off the heat and add the rest of the caramelized onions to the skillet and beef broth.

Bake The Stuffed Chicken Breast

Be sure to check the internal temperature of the chicken with a meat thermometer to ensure that it reaches at least 165°F (74°C).
