2. Prepare the Chicken
Preheat your oven to 400 degrees Fahrenheit. Pat the chicken breasts completely dry with paper towels on both sides. If any of the breasts are significantly thicker on one end, use a meat mallet or the bottom of a heavy pan to gently pound them to an even thickness of about three-quarters inch. Even thickness ensures all the chicken cooks at the same rate and stays juicy. In a small bowl, combine the salt, black pepper, Italian seasoning, and garlic powder. Drizzle the two tablespoons of olive oil over the chicken breasts and use your hands to rub it all over both sides. Sprinkle the seasoning mixture generously over both sides of each chicken breast, pressing it into the meat so it adheres well.
3. Make the Bruschetta Topping
Quarter the cherry or grape tomatoes and place them in a medium bowl. Cherry tomatoes work better than large tomatoes for this recipe because they’re sweeter, release less liquid, and maintain better texture during baking. Add the minced garlic, chopped fresh basil, three tablespoons of extra virgin olive oil, balsamic vinegar, salt, pepper, and dried oregano. Toss everything together gently but thoroughly. Let this mixture sit at room temperature while you prepare the baking dish. The brief marinating time allows the flavors to meld and the tomatoes to release some of their juices, creating a flavorful mixture that will infuse the chicken as it bakes.
4. Arrange Chicken in Baking Dish
Lightly grease a 9-by-13-inch baking dish with cooking spray or olive oil. Arrange the seasoned chicken breasts in the dish in a single layer, spacing them slightly apart if possible. They can be close together but shouldn’t be overlapping. The chicken will release some juices as it cooks, and having space between the pieces allows for better heat circulation and more even cooking. If your chicken breasts are particularly large, you may need to use a larger baking dish or two smaller dishes.
5. Top with Bruschetta Mixture
Using a slotted spoon, scoop the tomato mixture over and around each chicken breast, distributing it evenly among all six pieces. Make sure each breast is generously topped with tomatoes, garlic, and basil. It’s okay if some of the mixture falls into the baking dish around the chicken—those juices will add flavor and keep everything moist. Reserve any remaining liquid from the bowl to drizzle over the finished dish if desired. The fresh tomato topping will cook down slightly and become jammy while maintaining that bright, fresh bruschetta flavor.
6. Bake the Chicken
Place the baking dish in the preheated oven and bake uncovered for 20 minutes. During this time, the chicken will cook through and the tomatoes will soften and release their juices. The chicken should be nearly cooked through at this point, reaching an internal temperature of about 155 degrees Fahrenheit in the thickest part. Don’t skip this initial baking period before adding the cheese—if you add cheese too early, it may brown too much or become rubbery before the chicken is properly cooked.
7. Add the Cheese
After the initial 20-minute bake, carefully remove the baking dish from the oven. Sprinkle the shredded mozzarella cheese evenly over each chicken breast and the tomato topping. The cheese should cover most of the surface. Sprinkle the grated Parmesan cheese over the mozzarella layer. The combination of mozzarella and Parmesan provides both gooey, stretchy cheese and sharp, salty flavor. The cheeses will melt into the tomato mixture and create a delicious, cohesive topping.
8. Prepare the Crunchy Topping
In a small bowl, combine the panko breadcrumbs with the melted butter, chopped parsley, and chopped basil. Toss with a fork until the breadcrumbs are evenly coated and slightly clumpy. The butter helps the breadcrumbs brown and crisp up beautifully in the oven. Sprinkle this mixture evenly over the cheese-topped chicken breasts. Don’t pack it down, just distribute it loosely over the surface. This topping adds wonderful textural contrast to the tender chicken and soft tomatoes, creating crispy, golden bits that make each bite interesting.
9. Final Bake
Return the baking dish to the oven and bake for an additional 12 to 15 minutes until the cheese is completely melted and bubbly, the breadcrumb topping is golden brown and crispy, and the chicken reaches an internal temperature of 165 degrees Fahrenheit. The edges should be bubbling and you should see the tomato juices mingling with the melted cheese. If the breadcrumbs are browning too quickly before the cheese is fully melted, you can tent the dish loosely with aluminum foil for a few minutes. Remove from the oven once the chicken is cooked through and the topping is beautifully golden.
10. Rest and Serve
Let the casserole rest for 5 minutes before serving. This brief resting period allows the juices to redistribute throughout the chicken and makes it easier to serve without everything sliding around. Transfer each chicken breast to an individual serving plate using a spatula, making sure to get plenty of the tomato topping, melted cheese, and crispy breadcrumb layer with each piece. Drizzle each serving with balsamic glaze for that classic bruschetta finishing touch. Garnish with fresh basil leaves torn or left whole. Offer extra grated Parmesan at the table for those who want more cheese. Serve with a simple green salad, garlic bread, pasta, or roasted vegetables for a complete Italian-inspired meal.
Tips for Perfect Results
- Don’t skip pounding the chicken to even thickness. This is crucial for ensuring all pieces cook at the same rate and stay juicy rather than drying out.
- Pat the chicken completely dry before seasoning. Moisture prevents the seasonings from adhering and inhibits browning.
- Use fresh basil, not dried, for the bruschetta topping. Fresh basil provides that authentic, aromatic flavor that dried basil simply cannot replicate.
- Cherry or grape tomatoes work much better than large slicing tomatoes, which release too much liquid and can make the dish watery.
- Add the cheese only after the chicken has partially cooked. Adding it too early can result in overcooked, rubbery cheese by the time the chicken is done.
- Don’t overbake the chicken. Use an instant-read thermometer to check for 165 degrees Fahrenheit. Overcooked chicken breast becomes dry and tough.
- Let the casserole rest before serving. Cutting into it immediately causes all the juices to run out onto the plate, resulting in dry chicken.
- Make the tomato mixture while the chicken is baking to save time, or prepare it up to 2 hours ahead and refrigerate until ready to use.
- For meal prep, the entire casserole can be assembled (except the breadcrumb topping) up to 24 hours ahead. Cover tightly and refrigerate, then add the breadcrumb topping and bake, adding 5 to 10 minutes to the cooking time.
- Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 2 to 3 minutes or reheat the entire dish covered with foil in a 350-degree oven for 20 minutes. The breadcrumb topping won’t be as crispy after reheating, but the flavors remain excellent. This dish is also delicious cold or at room temperature, sliced and served over mixed greens as a hearty salad.
