Old Fashioned Sweet Potato Casserole With Marshmallows Recipe FAQs

How should I store leftover sweet potato casserole?
Very simply! Store leftovers in an airtight container in the fridge for up to 3 days. Ensure it s tightly sealed to retain its flavors. When it comes time to reheat, pop it into a preheated oven to keep that texture creamy and wonderful.

What can I do if my casserole seems too watery?
If you find your casserole too watery, try draining the mashed sweet potatoes a bit more next time. You can also consider increasing the amount of flour or corn starch to thicken the mixture slightly, or simply bake it longer to evaporate excess moisture, with the risk of drying it out.
Are there any dietary considerations I should be aware of?
Very much so! This Old Fashioned Sweet Potato Casserole contains eggs and dairy, making it unsuitable for vegans or those with dairy allergies.

To achieve that deliciously soft topping, add the marshmallows during the last 7-10 minutes of baking. Keep a close eye on them; this is when they puff up beautifully. If they start to brown too quickly, cover the casserole loosely with aluminum foil until you re ready to finish baking. Enjoy your creation!
