Ingredients You Need

This Sweet Potato Casserole ingredient list is all about bold flavors that actually work together! Here’s what you’ll need to make this crowd-pleaser happen:
- 4 large sweet potatoes (about 3 pounds), peeled and cubed
- 1/2 cup granulated sugar (I like the balance it brings, but honey works great for a natural twist)
- 1/3 cup melted butter (unsalted, because you’re controlling the salt levels in the mix)
- 1/2 cup whole milk or heavy cream (grab whichever you prefer for creaminess)
- 2 large eggs (for that perfect custardy texture)
- 1 teaspoon vanilla extract (this little flavor booster makes everything sing)
- 1/2 teaspoon ground cinnamon (optional but highly recommended)
- 1/4 teaspoon ground nutmeg (adds warm depth)
- 1/4 teaspoon salt (to balance the sweetness)
For the crunchy pecan topping:
- 1 cup chopped pecans (grab these at your regular grocery store, freshness matters for that crunch)
- 1/2 cup all-purpose flour
- 1/2 cup brown sugar
- 1/3 cup melted butter
For the marshmallow bake finish:
- 2 cups mini marshmallows (classic! You can even lean on marshmallow bake options like the Sweet Potato Casserole with Marshmallows and Streusel for inspo!)
If you’re short on time, no worries—canned sweet potato puree works in a pinch for making this casserole dish. I use it sometimes during busy weeknights when I crave bold flavors without the extra prep.
Tip: I love adding an extra handful of toasted pecans on top just before serving my Sweet Potato Casserole for that unexpected crunch explosion. You can keep leftovers fresh in the fridge, tightly wrapped, for up to 3 days—and bonus, they taste even better warmed up the next day with that gooey marshmallow bake still tempting your taste buds.

Let’s Make Some!
Alright fellow food lovers, I’m thrilled to walk you through this Sweet Potato Casserole! Ready to create some delicious magic?
- Preheat your oven to 350°F. This is where the magic starts happening!
- Cook the sweet potatoes. Toss your cubed sweet potatoes into a pot of boiling water and simmer until fork-tender, usually about 15-20 minutes. Drain well and get ready for the fun part.
- Mash the potatoes. Grab a big bowl and mash the sweet potatoes until smooth. In my kitchen, I love my mix a little chunky—it adds texture to the casserole.
- Mix in your sweet potato base ingredients: granulated sugar, melted butter, milk or heavy cream, beaten eggs, vanilla, cinnamon, nutmeg, and salt. Stir that all up until your Sweet Potato Casserole base looks like creamy heaven.
- Pour the mixture into a greased casserole dish (a classic 9×13 works perfectly here). Your Sweet Potato Casserole should smell absolutely incredible right now—sweet with that hint of spice teasing your senses!
- Whip up the pecan topping: combine chopped pecans, flour, brown sugar, and melted butter in a small bowl. Sprinkle this crumbly, buttery goodness generously over your potato base.
- Top with mini marshmallows evenly, covering the pecan topping—this marshmallow bake will caramelize beautifully while baking!
- Bake in the oven for about 25-30 minutes until the topping is golden brown and marshmallows are toasted to perfection. Don’t worry if your Sweet Potato Casserole looks super bubbly and gooey on top—that’s a happy accident!
- Remove from oven and let it cool slightly before serving. This rest time keeps everything perfectly set and ready for fork dives.
