- Overcooking the Onions – Caramelizing onions takes patience. Cook them on medium-low heat and stir occasionally to prevent burning.

- Using Cold Ingredients – Make sure your chicken and cream are at room temperature before adding them to the hot mixture. This helps maintain even cooking temperatures.
- Not Broiling Long Enough – Keep an eye on your casserole under the broiler. The cheese should be melted, bubbly, and slightly browned for the best texture.
