Rinse chicken breasts under fresh water then pat them dry using a paper towel. Transfer the raw chicken to a sealable plastic bag and set it aside.
Add Italian seasoning, minced garlic, balsamic vinegar, paprika, olive oil, black pepper, and salt to a small bowl. Whisk the marinade well to combine.
Pour the marinade over the chicken breasts and seal the bag. Massage the bag with your fingers, ensuring the chicken breasts are completely submerged in the marinade.
Transfer the bag to the refrigerator for one night or at least 2 to 4 hours.
Take the bag out of the refrigerator, remove the chicken and discard the marinade.
Prepare a baking dish by lightly spraying it with cooking oil, and place the chicken inside.
Place the baking dish in a preheated oven (425 degrees F) and bake for 20 to 25 minutes until the internal temperature of the thickest part of the chicken breast reaches 165 degrees F.
Once done, remove from the oven and let the chicken rest for 10 minutes.
For the Balsamic Glaze
As the chicken is baking, pour balsamic vinegar into a small saucepan over medium heat, add the sugar and bring the mixture to a boil. Decrease the heat to medium-low allowing it to simmer until the glaze thickens to your liking.
Slice chicken and serve with thick balsamic sauce on top.
Notes
If you are using frozen chicken, thaw it completely to eliminate any excess moisture.
You can also use dried herbs of your choice in place of Italian seasoning.
If you prefer grilled or pan-fried chicken, feel free to use those cooking methods.
Serve your balsamic chicken breast with cooked rice, mashed potatoes, salad, or roasted vegetables.
