Tips on Making Sweet Potato Casserole With Marshmallows

The sweet potato and marshmallow combo in this casserole dish is pure decadence. This version might be one of the most delightful sweet potato casserole recipes worth trying. On top of being a classic holiday food, it’s also the best pair for your steak dinners!

Follow these simple tips and tricks if you want to end up with the best marshmallow sweet potato recipe:

  • For a tastier result, use dark brown sugar! It’ll deliver a rich and deeper molasses flavor. If you fancy a delicate caramel flavor, go for light brown sugar instead.
  • Instead of boiling, you can also roast or bake the potatoes. This will make the potatoes taste a tad sweeter. Make sure to prick holes in the skin so they don’t explode as they roast.
  • For a crunchy spin, make a pecan streusel topping. Simply sprinkle the pecan topping over the sweet potatoes and bake until the top’s deliciously browned. Then, add the marshmallows and bake again for a few minutes. Sweet potato casserole with marshmallows and pecans is just cut above the rest! Feel free to stick to the recipe, though, if you want a potato casserole with no nuts.
  • For a healthier side dish, make a vegan version! Just opt for oat milk or nut milk and replace the eggs with flax seeds. And make sure to use vegan butter or olive oil. Of course, use vegan marshmallows for the topping!
  • If you have any leftovers, store them in the fridge for up to 4 days. When ready to eat, reheat in the microwave until warmed through.
  • To save on prep time, make your sweet potato casserole in advance! Assemble the casserole the day before baking. Then, store it in the refrigerator until ready to top with marshmallows and bake.

Frequently Asked Questions

Should I put eggs in my sweet potato casserole?

Yes. Never skip the eggs as they add structure, all while holding the ingredients together. The potatoes should be cooled enough before mixing the eggs (and the other ingredients), so they won’t scramble.

Is it better to boil or roast sweet potatoes for casserole?

Both methods yield deliciously cooked sweet potatoes for casseroles. However, it’s believed that boiling sweet potatoes preserves most of their antioxidant properties. Roasting, on the other hand, will make them sweeter!

How do I know when my sweet potato casserole is done?

Once the top is lightly browned and the center of your casserole is firm, your casserole is ready to serve!
