Can I make southern sweet potato casserole gluten free?

Yes! Simply swap the all purpose flour for your favorite gluten free flour blend.

Is this sweet potato dish vegan?

No, it’s not vegan! However, you can make it vegan by using vegan marshmallows, oat milk, and vegan butter.

Can I use canned sweet potatoes?

Sure! You can easily make this praline sweet potato casserole with canned sweet potatoes. Because they are already soft and cooked, you can skip boiling them. This will save you about 15-20 minutes, which is ideal when you are in a hurry.

What kind of sugar do I need?

I have used dark brown sugar and light brown sugar and they both work well. I prefer light brown sugar, only because I always have it in my pantry. However, dark brown sugar basically tastes the same as well.

Can I make sweet potato casserole ahead of time?

Of course! You will need to boil, mash and add ingredients to sweet potatoes. Then spread into a casserole dish and cover. Place in the fridge for up to 24 hours in advance. Remove the dish from the fridge 20-30 minutes before you are ready to cook. Then add the toppings and bake as directed. Enjoy!
