Ingredients

To make this delightful Sweet Potato Casserole with Marshmallows, gather the following ingredients:
– 2.5 lbs sweet potatoes, peeled and diced (or baked and peeled)
– 8 tablespoons (1 stick) unsalted butter, melted
– 1 (14 oz) can sweetened condensed milk
– 1 tablespoon ground cinnamon
– ½ teaspoon ground nutmeg
– ½ teaspoon salt
– 1 (16 oz) bag large marshmallows (or mini marshmallows)

Preparing the Sweet Potato Casserole

Preheat the Oven and Prepare the Dish

Start by preheating your oven to 350°F (175°C). While it heats up, spray a 9×13 casserole dish with non-stick spray and set it aside. This dish will be the home for all those creamy sweet potatoes and fluffy marshmallows.

Cook the Sweet Potatoes

In a large stock pot, add diced sweet potatoes and cover them with water. Cover the pot with a lid and bring it to a boil, cooking until the potatoes are fork-tender, which usually takes about 15 minutes. This step is crucial for achieving the perfect smooth texture.

Drain and Mash

Once cooked, drain the sweet potatoes and return them to the pot. Add the melted butter, sweetened condensed milk, cinnamon, nutmeg, and salt. Now, mash everything together until it becomes smooth and creamy, ensuring each bite is rich and flavorful.

Assemble the Casserole

Transfer the sweet potato mixture into the prepared baking dish, smoothing the top into an even layer. This layer of sweet potato will act as the delicious base for the marshmallows.

Top with Marshmallows and Bake

Generously line the top of the casserole with marshmallows. Once you have a cozy layer, bake in the preheated oven for about 15 to 20 minutes. You’ll want to watch closely until the marshmallows are lightly toasted, turning golden brown and providing that perfect contrast to the creamy sweet potatoes.

Serving Suggestions

This casserole is best served warm as a side dish during holidays or gatherings. Pair it with roasted meats or plant-based proteins to create a balanced meal. The combination of flavors will have everyone coming back for seconds!

Tips for Success

Ensure that the sweet potatoes are cooked until very tender for the smoothest texture possible.
Consider using mini marshmallows for easier distribution across the casserole. They tend to melt a bit faster, adding to that delightful gooeyness.

Variations

Want to add a bit of crunch? Try adding crushed pecans or walnuts beneath the marshmallows for a lovely texture contrast.
A splash of vanilla extract can also boost the flavor, making each bite even more enticing.

Storage Tips

For any leftovers, store them in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy them again, gently reheat in the oven to maintain the marshmallow’s lovely texture.

FAQs

1. Can I make this casserole ahead of time?
Definitely! You can prepare the sweet potato mixture and store it in the fridge. Just remember to top it with marshmallows and bake it when you’re ready to serve.

2. Is it possible to use fresh sweet potatoes instead of canned?
Absolutely! Fresh sweet potatoes provide a wonderful flavor and texture. Just ensure they are cooked until very tender for the best results.

3. Can I substitute the sweetened condensed milk?
Yes, you can use coconut milk for a dairy-free version. Keep in mind that the flavor may be slightly different, but it’s still delicious.

4. How do I avoid soggy marshmallows?
Baking until lightly toasted helps reduce moisture buildup. Make sure your casserole is heated through before adding marshmallows to keep them fluffy.

5. What’s the best way to reheat leftovers?
Reheat in the oven at 350°F, covered with foil to preserve texture. You can uncover it at the end for a quick toast on the marshmallows.
