Sweet Potato Casserole Recipe

Ingredients

For the Sweet Potato Base

• 4 large sweet potatoes (about 3 pounds)
• 1/2 cup unsalted butter, softened
• 1/4 cup whole milk
• 1/2 tsp ground cinnamon
• 1/4 tsp ground nutmeg
• 1/4 tsp salt

For the Combined Topping

• 1 cup chopped pecans
• 1/3 cup all-purpose flour
• 1/3 cup brown sugar
• 1/4 cup unsalted butter, melted
• 1/4 tsp ground cinnamon
• 2 cups mini marshmallows

How to Make

1. Preheat your oven to 375°F (190°C).
2. Wash the sweet potatoes and pierce them several times with a fork. Place them on a baking sheet lined with foil.
3. Bake the sweet potatoes for 1 hour or until they’re tender when pierced with a fork.
4. Remove the sweet potatoes from the oven and let them cool slightly. Reduce the oven temperature to 350°F (175°C).
5. Once cool enough to handle, peel the sweet potatoes and place the flesh in a large mixing bowl.
6. Add the softened butter, milk, cinnamon, nutmeg, and salt to the sweet potatoes.
7. Mash the mixture until smooth and well combined. You can use a potato masher or an electric mixer for a smoother consistency.
8. Transfer the sweet potato mixture to a 9×13 inch baking dish, spreading it out evenly.
9. In a medium bowl, mix together chopped pecans, flour, brown sugar, melted butter, and cinnamon until well combined to create the pecan streusel.
10. Sprinkle the pecan streusel evenly over the sweet potato base.
11. Bake at 350°F (175°C) for about 20 minutes, until the pecan topping starts to brown.
12. Remove the casserole from the oven and quickly sprinkle the mini marshmallows evenly over the pecan topping.
13. Return the casserole to the oven and bake for an additional 5-10 minutes, or until the marshmallows are golden brown and puffy.
14. Keep a close eye on the casserole during the final minutes to prevent the marshmallows from burning.
15. Remove from the oven and let it cool for a few minutes before serving.

Tips for Success

This casserole pairs wonderfully with roast turkey, ham, or even as a unique side to grilled meats. It’s also delicious served alongside green beans, cranberry sauce, and stuffing for a complete holiday meal.

• Look for sweet potatoes that are firm, smooth, and free of blemishes or soft spots. Medium-sized potatoes tend to have the best flavor and texture.
• While you can boil the sweet potatoes, roasting them as described in this recipe enhances their natural sweetness and gives a richer flavor.
• The sweetness of this casserole comes from three sources: the sweet potatoes themselves, the brown sugar in the pecan streusel, and the marshmallows. Adjust these elements to suit your taste preferences. For a less sweet version, you can reduce the amount of brown sugar or marshmallows.
• The combination of creamy sweet potatoes, crunchy pecans, and gooey marshmallows creates an exciting texture profile. Ensure your sweet potato base is smooth and creamy for the best contrast with the toppings.
• For enhanced flavor, try toasting the pecans lightly before adding them to the streusel mixture. This brings out their natural oils and intensifies their nutty taste.
• You can prepare the sweet potato base and the pecan streusel up to 2 days in advance. Store them separately in the refrigerator. When ready to bake, bring the sweet potato base to room temperature, assemble the casserole, and add the marshmallows just before the final baking step.
• To reheat, cover the casserole with foil and warm in a 325°F (165°C) oven until heated through. Remove the foil for the last few minutes to re-crisp the marshmallows.
• Flavor ideas:
  • For extra richness, you can substitute heavy cream for the milk.
  • If you prefer a nuttier flavor, add 1/2 cup of chopped pecans to the sweet potato mixture before baking.
  • Try adding a tablespoon of orange zest for a citrusy twist.
  • For a more complex flavor profile, consider adding a pinch of chipotle powder or smoked paprika.
• For a lighter version, you can reduce the amount of butter and use low-fat milk. You could also experiment with natural sweeteners like maple syrup or honey instead of relying solely on the marshmallows for sweetness.
• For an extra special touch, try using flavored marshmallows like vanilla or cinnamon. You can even use a combination of regular and flavored marshmallows for more depth of flavor.

This casserole is best served warm, but not piping hot. Letting it cool for 5-10 minutes after baking allows the flavors to meld and makes serving easier.
