Why We Love this Sweet Potato Casserole Recipe

The holidays wouldn’t be the same without a big sweet potato casserole dish. Something about the potatoes’ earthiness, the pecans’ crunch, and the marshmallows’ sweetness screams “festive.” 

I think it’s the memories of childhood holidays gathered around the table with loved ones, or maybe it’s just that sweet potatoes are so darn delicious.

One of the best things about sweet potato casserole is its unique texture. The smooth, rich flesh of the sweet potatoes pairs perfectly with the crunchy topping, creating a dish that is both creamy and crisp.

We usually use canned sweet potatoes because it makes it super simple. However you can use fresh sweet potatoes if you prefer.

The secret to achieving the perfect smooth texture is to use fresh sweet potatoes that have been roasted or steamed until they are fork-tender.

Once mashed, the potatoes are combined with brown sugar, maple syrup, butter and spices to create a smooth filling.

For the topping, sprinkle with chopped pecans and miniature marshmallows. You can sprinkle both over the entire pan or alternate them for a striped effect.

Variations to Make Sweet Potato Casserole 

While this recipe for sweet potato casserole calls for marshmallows and pecans, there are many ways to give this dish a unique twist. Try making a sweet potato casserole with an oat and pecan topping if you like more crunch and no marshmallows.

You can also stir in some raisins or dried cranberries for a touch of chew and sweetness. Or try using walnuts instead of pecans for a slightly different flavor.

For a healthier option, use diced fruit instead of marshmallows and dark honey instead of brown sugar. You could also use pumpkin pie spice instead of cinnamon and nutmeg if you would like.

Whatever variations you choose, sweet potato casserole will be a hit at your dinner table. And if you are like me, you might find yourself eating the leftovers for breakfast!
