FAQs
Can I use frozen sweet potato slices for this recipe?
It’s best to use fresh sweet potatoes for roasting to achieve a tender yet crispy texture. Frozen slices tend to become mushy and don’t brown as well.
Can I make this recipe vegan?
Yes! Simply replace the butter with a plant-based alternative and use a vegan Parmesan substitute or nutritional yeast for a cheesy flavor without dairy.
