Common Mistakes to Avoid
Avoiding common mistakes can elevate your Southern Squash Casserole from good to great. Here are some pitfalls to watch out for:
- Not salting the squash: Failing to season the squash can lead to blandness. Always sprinkle salt while cooking to enhance flavor.
- Overcooking the squash: Cooking the squash too long will make it mushy. Aim for tender, but not fully soft, before combining with other ingredients.
- Skipping the cooling step: Adding hot squash directly into the creamy mixture can cause curdling. Allow it to cool slightly before mixing.
- Using stale crackers: Old crackers won’t provide the desired crunch on top. Ensure your Ritz crackers are fresh for the best texture.
- Underbaking the casserole: Not baking long enough can result in a soggy dish. Look for a golden brown top and bubbling edges as indicators of doneness.
