How to Perfect Butternut Squash Casserole

Experiment with Spices: Adding spices like nutmeg or ginger can elevate your casserole’s flavor profile. Start small and adjust as needed.

Don’t Overbake: Keep an eye on baking times to avoid drying out the casserole. It should be set but still moist when you take it out of the oven.
