How to Make Creamy Chicken and Spinach Casserole
Preheat your oven to 180 °C / 350 °F. This step gets your kitchen warm and ready for all that comforting goodness to bake beautifully, with a golden finish waiting for you!
Grease a 9 13-inch baking dish with olive oil or butter to prevent sticking. This will also help create that delightful crispy edge you ll love when the casserole comes out of the oven.
Mix together the chicken, spinach, cooked rice or pasta (if using), cream soup, sour cream, garlic powder, onion powder, salt, and pepper in a large bowl. Combine until everything is coated and unified, giving you that creamy filling.
Stir in half of the shredded cheddar cheese and half of the grated Parmesan. This adds a lovely cheesy texture that ll melt and blend with the other ingredients as they bake.
Transfer the mixture into your greased baking dish. Spread it out evenly, so every scoop boasts that wonderful medley of flavors, making sure you got every bit perfectly placed.
Sprinkle the remaining cheddar and Parmesan on top for that extra layer of cheesy goodness. This will create a delightful crust when baked, oozing with flavor and enticing aromas.
Bake uncovered for 25 30 minutes, or until the cheese is melted and bubbly. Keep an eye on it until that glorious golden color appears, signaling it s ready to enjoy!
Cool for 5 minutes before serving. This slight pause makes sure every bite holds together beautifully, allowing the flavors to settle just perfectly.
Optional: Garnish with fresh herbs like parsley for a vibrant touch!
