Step 1: Preheat the Oven
- Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish with a little olive oil or cooking spray.
Step 2: Cook the Chicken
- Sauté the Chicken: In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add the chicken pieces and cook for about 5-7 minutes, stirring occasionally until the chicken is browned and cooked through. Season with salt and pepper to taste.
- Set Aside: Once the chicken is cooked, remove it from the skillet and set aside.
Step 3: Sauté the Vegetables
- Cook the Onion and Garlic: In the same skillet, add the diced onion and garlic, and sauté for about 2-3 minutes until fragrant and soft.
- Add Vegetables: Add the broccoli, carrots, red bell pepper, and zucchini to the skillet. Season with Italian seasoning, salt, and pepper, and cook for another 5-6 minutes until the vegetables are slightly softened but still have a bit of crunch.
Step 4: Prepare the Casserole
- Mix Chicken and Vegetables: In a large bowl, combine the cooked chicken and sautéed vegetables. Add chicken broth and heavy cream, stirring to combine. This mixture will create a creamy base for the casserole.
- Transfer to Baking Dish: Pour the chicken and vegetable mixture into the prepared baking dish, spreading it out evenly.
Step 5: Add the Cheese
- Layer Mozzarella: Sprinkle 1 1/2 cups of shredded mozzarella evenly over the top of the casserole.
- Parmesan Topping: Sprinkle grated Parmesan cheese over the mozzarella for an extra cheesy, golden top.
Step 6: Bake the Casserole
- Bake the casserole in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden brown on top.
Step 7: Garnish and Serve
- Garnish: Once out of the oven, let the casserole cool for a few minutes before serving. Garnish with freshly chopped parsley for a pop of color and freshness (optional).
- Serve: Scoop generous portions onto plates and enjoy the cheesy, comforting goodness of this chicken and vegetable casserole.
Tips for the Best Chicken & Vegetable Casserole
- Use Fresh or Frozen Vegetables: Fresh vegetables are great, but you can also use frozen ones. Just make sure to thaw and drain them properly to avoid excess moisture.
- Add More Veggies: Feel free to swap or add vegetables based on what you have on hand—mushrooms, spinach, or green beans work well, too.
- Cheese Variations: If you’re a cheese lover, try mixing mozzarella with other cheeses like cheddar or provolone for extra flavor.
