Frequently Asked Questions
How do you keep marshmallows from burning on sweet potato casserole?
To prevent burning, broil the marshmallows for only a minute or two, keeping a close eye on them. You can also tent the casserole with foil for most of the baking time, removing it only towards the end to brown the marshmallows.
Can I make sweet potato casserole with marshmallows ahead of time?
Yes, you can assemble the casserole a day or two in advance and store it in the refrigerator. Add the marshmallows right before baking to prevent them from getting soggy.
What are some good substitutions for marshmallows in sweet potato casserole?
If you don’t want to use marshmallows, consider a pecan crumble topping. Simply combine pecans, flour, brown sugar, and butter for a crunchy and flavorful alternative. Another option is a streusel topping with oats and cinnamon.
How do I get the perfect creamy texture for my sweet potato casserole?
Make sure to cook your sweet potatoes until they are very soft before mashing. Adding a bit of cream, butter, or milk will also help to achieve a smooth and creamy consistency. Avoid over-mixing, which can make the sweet potatoes gummy.
