Common Mistakes to Avoid
Making the perfect Healthy Buffalo Chicken Casserole can be simple, but avoiding common mistakes is essential for the best results.

- Skipping the Veggies: Don’t skip the vegetables! They add flavor, nutrition, and texture to your casserole. Make sure to include carrots, bell peppers, and onions as specified.
- Overcooking the Chicken: If you’re using raw chicken, make sure it’s cooked just right. Overcooked chicken can turn dry and tough. Use shredded cooked chicken for best results.
