Sweet Potato Casserole with Marshmallows

Sweet Potato Casserole with Marshmallows is a comforting dish with a balance of flavors – the earthiness of sweet potatoes, the warmth of spices, and the sugary sweetness of marshmallows. The caramelized marshmallows on top are the perfect topping for the casserole. This is a great side dish for your holiday meal at Thanksgiving or Christmas that your guests will love!

SWEET POTATO CASSEROLE WITH MARSHMALLOWS

When the holidays roll around we are all looking for side dishes we can pair with our Apple Cider Glazed Ham or this Herbed Butter Roasted Turkey. 

Today’s Sweet Potato Casserole with Marshmallows is a side dish that is the perfect balance of sweet and savory flavors.

It reminds me of these Easy Scalloped Sweet Potatoes I posted last year for the holidays. 

If you are going to have kids at your holiday meal this is a great one to serve.

Kids love the marshmallow topping!

This casserole is a classic thanksgiving side dish in the United States. 

I love to serve this easy Thanksgiving or Christmas side dish alongside this Lemon Arugula Salad with Parmesan Cheese, Cheesy Butternut Squash Orzo and these Roasted Balsamic Mushrooms.

What I love most about this sweet potato casserole is the warm cinnamon, nutmeg and allspice paired with brown sugar, vanilla and syrup.

This really compliments the earthy sweet potatoes and goes nicely with the sweet marshmallows that finish it off. 

You need this on your thanksgiving table or Christmas dinner.

Sweet Potato Casserole with Marshmallows ingredients

WHAT INGREDIENTS ARE IN THIS CLASSIC SWEET POTATO CASSEROLE RECIPE 

  • SWEET POTATO: Stick to the red or orange sweet potatoes and now the white or purple ones as those have too high of a starch count for this casserole. You will want to peel and cut into large cubes.
  • SUGAR: Sweeten the casserole with brown sugar as it has the best depth of flavor for this dish.
  • BUTTER: I added unsalted butter to control the salt. If you are using salted butter cut back a little on the salt.
  • VANILLA: I use vanilla extract as it has the best depth of flavor. In a pinch you can also use vanilla essence but it won’t have the same flavor.
  • MAPLE SYRUP: Maple syrup is the perfect way to sweeten a casserole. It pairs nicely with the pecans too.
  • NUTS: Some chopped pecans add great crunch and texture to the top of the casserole.
  • SPICES: I add ground cinnamon, nutmeg and allspice to the sweet potato mixture and also sprinkle some over the casserole at the end of the cook. I love the warm flavor it adds.
  • MARSHMALLOWS: This recipe uses mini marshmallows but you can also use regular marshmallows. I suggest not skipping the marshmallows. There is just something so good about that gooey marshmallow topping.

HOW TO MAKE SWEET POTATO CASSEROLE WITH MARSHMALLOWS?

PREHEAT THE OVEN: Start by preheating the oven to 375°F. Grease a 9 x 13-inch casserole dish or baking dish.

COOK THE SWEET POTATOES: Add water to a large pot and boil water on medium high heat.

Place sweet potatoes in the pot of boiling water.

Simmer the sweet potatoes for 15-20 minutes or until the potatoes are fork tender. Drain the water.

WAYS TO MODIFY THIS EASY SWEET POTATO CASSEROLE RECIPE

SQUASH: I’ve used sweet potato in this recipe, but pumpkin or butternut squash would be good substitutes in this sweet potato casserole.

SPICES: I’ve used ground cinnamon, but you could also use pumpkin pie spice blend or even apple pie spice.

NUTS: Leave out the nuts for anyone with a nut allergy and you will still have a great tasting casserole.

TOPPING: You can skip the marshmallows for a lower sugar option. Try adding more chopped nuts, crushed graham crackers or make a streusel topping made from oats, butter and brown sugar. 

SPICY TWIST: You can spice this casserole up by using a pinch of crushed red pepper flakes or cayenne pepper. 

FRUIT: Dried fruit would be a fun addition. Try dried cranberries, pineapples, raisins or apricots. 

VEGAN: Make this vegan but using vegan marshmallows and using dairy-free butter.

TIPS AND NOTES FOR THE BEST SWEET POTATO CASSEROLE

DON’T OVERCOOK THE SWEET POTATOES: Be careful not to overcook the potatoes, as they will absorb too much water and leave you with a watery casserole.

TO THICKEN THE CASSEROLE: If you need to thicken the casserole, add 1-2 tablespoons of flour to the sweet potato batter.

DOUBLE THE RECIPE: This recipe is easily doubled up if you are feeding a crowd, just increase the size of pan or use 2 separate pans.

LEFTOVERS: Leftovers can be stored in an airtight container in the fridge for 2-3 days, although the marshmallows will melt into the sweet potato.

To reheat the casserole place back into a warm oven or heat up in the microwave. You can add extra marshmallows on top if you wish.

STORAGE: Store the casserole in an airtight container in the fridge for up to 3 days. 

Or freeze the casserole without the marshmallow topping for up to 3 months. Just be aware that the texture of the potatoes may change during the freezing and defrosting process.
