1. Old Fashioned Sweet Potato Casserole Recipe

Ingredients

For the Sweet Potato Base

  • 4 large sweet potatoes (about 3 pounds)
  • 1/2 cup unsalted butter, melted
  • 1/4 cup packed light brown sugar
  • 1/4 cup granulated sugar
  • 1/2 cup whole milk
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • Pinch of salt

For the Streusel Topping

  • 1/2 cup all-purpose flour
  • 1/2 cup packed light brown sugar
  • 1/4 cup unsalted butter, softened
  • 1/2 cup chopped pecans

Optional Marshmallow Topping

  • 2 cups miniature marshmallows (if you prefer a marshmallow topping)

Instructions

Step 1. Prepare the Sweet Potatoes

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick cooking spray.

Place the sweet potato chunks in a large pot, cover them with water, and bring to a boil. Cook for about 15-20 minutes, or until the sweet potatoes are fork-tender.

Drain the potatoes and return them to the pot. Mash until smooth using a potato masher or a hand mixer for a creamier texture.

Step 2. Make the Sweet Potato Mixture

Add the melted butter, brown sugar, granulated sugar, milk, eggs, vanilla extract, cinnamon, nutmeg, and salt to the mashed sweet potatoes. Mix until everything is well combined and smooth.

Taste the mixture and adjust the sweetness or spice levels to your preference.

Transfer the sweet potato mixture into the prepared baking dish, spreading it evenly.

Step 3. Prepare the Streusel Topping

In a medium bowl, combine the flour, brown sugar, and softened butter. Mix together with a fork or your hands until the mixture resembles coarse crumbs.

Stir in the chopped pecans until they are evenly distributed.

Sprinkle the streusel topping evenly over the sweet potato mixture.

Step 4. Bake the Casserole

Bake the casserole for 30-35 minutes, or until the streusel topping is golden brown and the sweet potatoes are heated through.

If you prefer a marshmallow topping, add mini marshmallows on top of the casserole during the last 5-10 minutes of baking. Continue baking until the marshmallows are puffed and golden brown.

Step 5. Cool and Serve

Remove the casserole from the oven and let it cool for about 10 minutes before serving. This allows the casserole to set slightly and makes it easier to serve.

2. Variations

Savory Sweet Potato Casserole: If you prefer a more savory dish, cut back on the sugar in the sweet potato mixture and add a touch of thyme or sage instead. Top with a Parmesan and breadcrumb mixture for a savory twist.

Vegan Sweet Potato Casserole: Substitute the butter with vegan butter or coconut oil, and replace the eggs with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water). Use almond milk or another plant-based milk, and top with a pecan crumble instead of marshmallows.

Maple-Pecan Sweet Potato Casserole: Swap out the brown sugar in the topping for maple syrup to give the casserole a rich, deep sweetness. The pecans and maple syrup create a wonderful combination that enhances the earthy flavor of the sweet potatoes.
