Step 5: Assemble the Casserole
- Transfer to a Baking Dish: Spread the chicken mixture evenly into a greased 9x13-inch baking dish.

Step 6: Bake
- Bake the Casserole: Bake in the preheated oven for 20-25 minutes, or until the casserole is hot and bubbly and the cheese on top is melted and golden.
Step 7: Cool and Garnish

Common Mistakes to Avoid
- Not Softening the Cream Cheese: Make sure the cream cheese is softened before mixing to avoid lumps in the casserole.

- Too Much Jalapeño Heat: If you're sensitive to spice, make sure to remove the seeds and membranes from the jalapeños to reduce the heat.
- Undercooking the Chicken: Make sure your chicken is fully cooked before mixing it into the casserole to avoid undercooking in the oven.
