How to Make chicken zucchini casserole
1. Preheat the oven to 350°F (175°C). This step ensures your casserole bakes evenly, creating that deliciously golden and bubbly top we all crave.
2. Combine shredded chicken, sliced zucchini, cream of chicken soup, milk, garlic powder, onion powder, salt, and pepper in a skillet. Stir well until everything is nicely blended together, making it flavorful and creamy.
3. Transfer the mixture to a greased casserole dish. Spread it out evenly so each bite will be packed with tender chicken and fresh zucchini goodness.
4. Sprinkle the bread crumbs evenly over the top of the mixture, followed by the shredded cheddar cheese. This will create a mouthwatering crust that adds a delightful crunch.
5. Bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly. You’ll know it’s ready when it fills your kitchen with an irresistible aroma!
6. Let cool for a few minutes before serving. This brief pause allows the casserole to set slightly, making it easier to serve while still warm and inviting.
