Common Mistakes to Avoid

- Using raw chicken: Always use cooked, shredded chicken in your casserole. Cooking the chicken ensures it’s safe and tender.

- Ignoring seasoning: Don’t skip on the spices! Proper seasoning enhances the dish. Adjust chili powder, cumin, and salt to your taste.
- Not greasing the baking dish: Greasing prevents sticking and makes serving easier. Always grease your dish before adding the mixture.
- Skipping cheese on top: Cheese adds a delightful gooeyness. Make sure to top your casserole with cheese for that irresistible finish.
