1.Preheat oven to 350 degrees.
2.Season chicken on both sides with garlic, onion, and Italian seasoning. Save the remaining for sauce.
3.Place an oven-safe skillet ( I love this reasonably priced skillet, it’s large and can go into an oven up to 550 degrees) over medium-high heat. Add olive oil and heat until hot. Carefully add the chicken breasts to the skillet. Allow to brown on the first side, about 3 to 4 minutes, before flipping. This will keep chicken from sticking to pan.
4.Top chicken breast with grated Parmesan cheese.
5.Open can of tomatoes, Add in leftover seasonings. Stir gently. Pour over chicken in skillet. Let cook for about 2 to 3 minutes to heat through.
6.Now, add mozzarella cheese over each chicken breast.
7.Place skillet in oven and cook for 20 minutes or until chicken reaches an internal temperature of 165 degrees and juices run clear.
8.While chicken is in the oven, prepare pasta, rice or vegetables.
9.Take out of oven and let rest in pan on a cooling rack for about 5 minutes. Serve over the pasta, rice or vegetables. Enjoy!
