How to Make Bruschetta Chicken Casserole

Step 1: Preheat and Prep

Preheat your oven to 375°F. Give your 8×8-inch baking dish a light mist of cooking spray or brush it with oil to keep everything from sticking and to make serving a breeze.

Step 2: Sear the Chicken

On the stovetop, heat your oil in a skillet over medium-high. Add those chicken bites and season with a good sprinkle of sea salt and black pepper. Sauté, stirring occasionally, until the pieces are golden on the edges and cooked almost all the way through. Don’t worry about cooking them completely they’ll finish in the oven.

Step 3: Layer and Assemble

Spread the cooked chicken evenly in your baking dish. Scatter the chopped, salted tomatoes across the top, followed by the chopped garlic and oregano. Drizzle evenly with balsamic vinegar this step is magic for flavor!

Step 4: Cheese It Up

Sprinkle your shredded mozzarella all over the top. Don’t be shy this is where the gooey magic happens.

Step 5: Bake

Pop the dish into your hot oven, uncovered, and bake for 18-20 minutes. You’re looking for melty cheese and bubbling juices—the aroma will tell you it’s time!
