Common Mistakes to Avoid
When making Green Chile Cauliflower Casserole, it’s easy to overlook some details. Here are common mistakes to watch out for:

- Overcooking the vegetables – Cooking vegetables too long before adding them can result in a mushy texture. Aim for tender-crisp when sautéing.
- Skipping the cheese topping – The cheesy crust is one of the best parts! Don’t forget to reserve some cheese for topping before baking.
- Baking at the wrong temperature – Ensure your oven is preheated correctly. Baking at an improper temperature can affect how well it sets and browns.
