Preheat the oven and prepare your baking dish
Start by preheating your oven to 375°F (190°C). This ensures your casserole bakes evenly, giving you that perfect cheesy, golden finish. While your oven warms up, grab a medium-sized baking dish—about 9×13 inches works well. Lightly grease it with olive oil or non-stick spray to prevent sticking. This ensures you’ll have a beautiful presentation when it’s time to serve your bruschetta chicken casserole.
Sauté the chicken to a golden perfection
Next up, it’s time for the star of the show: the chicken. For this dish, you can use about 3 cups of diced cooked chicken (leftovers work wonderfully!). If you’re starting with raw chicken, cut it into bite-sized pieces and season with salt, pepper, and a hint of Italian seasoning to imbue flavor throughout.
