Sweet Potato Casserole with Marshmallows
- Total Time: 45 minutes
- Yield: 8 servings 1x
Description
A classic comfort dish that blends velvety sweet potatoes with cinnamon and nutmeg, topped with toasted marshmallows.
Ingredients
- 4 large sweet potatoes (about 2 pounds), peeled and cubed
- 1/2 cup brown sugar (light or dark)
- 1/2 cup milk (whole or any non-dairy alternative)
- 1/2 cup unsalted butter, softened
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 teaspoon cinnamon
- 1/2 teaspoon nutmeg
- 1/4 teaspoon salt
- 2 cups mini marshmallows
Instructions
- Start by preheating your oven to 350°F (175°C). Prepare a 9×13-inch baking dish by greasing it lightly with butter or cooking spray to prevent sticking.
- Bring a large pot of salted water to a boil. Add your cubed sweet potatoes and cook until they are tender, about 15-20 minutes. You can test doneness by piercing them with a fork; they should be soft and easy to mash.
- Drain the sweet potatoes and transfer them to a large mixing bowl. Mash them until smooth using a potato masher or an electric mixer for a creamier texture.
- To the mashed sweet potatoes, add the brown sugar, milk, softened butter, eggs, vanilla extract, cinnamon, nutmeg, and salt. Mix well until everything is combined and smooth. Taste and adjust the sweetness or spices to your liking.
- Pour the sweet potato mixture into the prepared baking dish. Use a spatula to spread it evenly across the dish.
- Bake the casserole in the preheated oven for about 25 minutes, allowing it to set and develop a delicious crust.
- After 25 minutes, remove the casserole from the oven and sprinkle the mini marshmallows evenly on top.
- Return the casserole to the oven and bake for an additional 5-10 minutes or until the marshmallows are golden and toasted. Keep a close eye so they don’t burn!
Notes
For a vegan version, swap the butter with coconut oil and use a flaxseed egg as a substitute for the eggs. To reduce sugar, consider using coconut sugar or a sugar-free sweetener.

Healthier Alternatives
If you want to lighten up your dish or tailor it to meet specific dietary needs, here are some modifications to consider:
- Choose a sugar substitute, like stevia, for a low-calorie option without losing sweetness.

Common Mistakes to Avoid
Even the most seasoned cooks can stumble when making this sweet treat. Here’s how to navigate some common pitfalls:
- Overcooking Sweet Potatoes: Ensure you don’t overcook them; they should be tender but not mushy. This impacts the texture of your casserole.
- Too Many Marshmallows: While marshmallows are a delightful topping, too many can make the dish overly sweet. Stick to the recommended amount for balance.
- Not Letting it Cool: Allow the casserole to set for a few minutes before serving. This helps in slicing and plating without falling apart.
Storage Tips
If you find yourself with leftovers or wish to make this dish ahead of time, follow these handy tips:
- Refrigeration: Store covered in the refrigerator for up to 3-5 days. Reheat in the oven at 350°F for about 15 minutes or in the microwave until warmed through.
- Freezer Storage: You can freeze the casserole before or after baking. Just make sure it’s well-wrapped to prevent freezer burn. It will last up to 2-3 months.
- Meal Prep Suggestions: Consider doubling the recipe for larger gatherings. It can easily be frozen and served later, making life easier during busy holiday seasons.
