Step-by-Step Instructions

1. Prepare the oven
   Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking. Allowing the oven to fully preheat ensures even baking from the start.

   If using rotisserie chicken, remove the skin and shred the meat into bite-sized pieces. Measure approximately 3 cups of cooked chicken. Set aside while preparing the remaining ingredients.
3. Mix the wet ingredients
   In a large mixing bowl, whisk together: Eggs, Milk, Melted butter. Continue whisking until the mixture appears smooth and fully combined.
4. Add the dry ingredients
   Sprinkle in the flour, salt, and black pepper. Whisk carefully until no visible lumps remain. The mixture should have a smooth consistency similar to pancake batter.
5. Add the chicken and cheese
   Fold the shredded chicken into the bowl. Add most of the cheddar cheese, reserving about ½ cup for the topping. If using green onions, stir them in now. Mix gently until everything is evenly distributed.
6. Assemble the casserole
   Pour the mixture into the prepared baking dish. Spread evenly with a spatula so the casserole cooks uniformly. Sprinkle the remaining cheese over the top. This cheesy topping will become beautifully golden during baking.
7. Bake until golden
   Place the casserole in the center rack of the oven. Bake for 40 to 45 minutes. You’ll know it’s ready when: The center is set, The edges are lightly golden, The cheese is melted and bubbly, A knife inserted in the center comes out mostly clean.
8. Rest before serving
   Allow the casserole to rest for 10 minutes after removing it from the oven. This helps the casserole firm up and makes slicing much easier. Serve warm and enjoy.
