The first step to making this caprese chicken is to cut and season the chicken breast. To cut the chicken’s pockets, you’ll need a sharp, thin-bladed knife. Then start at the thickest part of the breast and work your way in. Just watch that you don’t cut all the way through.
Season both sides of the chicken breast. I'm using a salt, pepper, and garlic seasoning blend called Kinder's that I found on Amazon. This combination is fantastic. I use it to make these delicious Juicy Pork Chops. You can, however, use garlic powder, salt, and pepper separately. I also added smoked paprika and oregano. Stuff each chicken breast with slices of fresh tomato, fancy pimientos (which are delicious), sun-dried tomato strips, one or two slices of mozzarella cheese, and basil leaves.
Fold it all in really tight, or if you want, you can seal it with 3-4 toothpicks placed diagonally to keep the filling inside while cooking. In my case, I didn’t find that necessary, as I don’t mind the cheese sticking out while cooking.
Preheat oven to 350°F, and let’s prepare the balsamic sauce:
Mix together the garlic, balsamic vinegar, and brown sugar in a small jug and set aside.
Then, pan-seared the chicken breast. In an oven-safe skillet, heat 1 teaspoon of oil over medium-high heat. Once the oil is hot, carefully place the chicken in the pan. Then, cook the chicken on each side for 3 minutes or until browned.
Pour the balsamic mixture into the pan around the chicken; bring to a simmer while stirring occasionally, until the glaze has slightly thickened (about 2-3 minutes).
Transfer to the preheated oven and bake for 10-15 minutes, or until the internal temperature reaches 165°F (74°C). Check if you’ve reached these temperatures by putting a meat thermometer in the thickest part of the breast.
