A delightful and creamy chicken and vegetable casserole, perfect for a comforting meal.
Preheat your oven to 400°F (200°C).
Ensure the oven is fully preheated to achieve even cooking.
In a mixing bowl, combine the cooked chicken, celery, onion, water chestnuts, shredded cheddar cheese, mayonnaise, lemon juice, salt, and pepper.
Mix thoroughly to ensure all ingredients are evenly distributed.
Transfer the mixture into a casserole dish and spread it out evenly.
Use a spatula to smooth the top for even baking.
Bake the casserole in the preheated oven for 20 minutes, or until heated through and the top is slightly golden.
Check halfway through to ensure it doesn't overcook.
Serve the casserole warm and enjoy!
Garnish with fresh parsley for added color and flavor.
