Ingredients You’ll Need
Here’s what goes into creating this dreamy casserole:
🥔 For the Sweet Potato Base:
- Fresh sweet potatoes (4–5 medium)
- Plant-based or dairy butter (softened)
- Brown sugar
- Ground cinnamon
- Ground nutmeg
- Pure vanilla extract
- A splash of plant milk (or dairy if preferred)
- Pinch of salt
🔥 For the Marshmallow Topping:
- Mini marshmallows (lots of them!)
Optional add-ins:
- A pinch of ground ginger for spice
- A splash of orange juice for brightness
- Chopped pecans (if you love a crunch under your marshmallow topping)
Step-by-Step Instructions
Follow these simple steps to bring it all together:
🧊 Step 1: Prep the Sweet Potatoes
Peel and chop sweet potatoes into large chunks. Boil in salted water until fork-tender (about 15–20 minutes). Drain well.
🧈 Step 2: Mash the Base
In a large bowl, mash the sweet potatoes with butter, brown sugar, spices, vanilla, and a splash of milk until smooth and fluffy. You want a creamy, slightly whipped consistency.
🍽️ Step 3: Layer It In
Spread the sweet potato mixture evenly into a greased 9×13-inch baking dish. Smooth the top with a spatula.
🔥 Step 4: Marshmallow Magic
Sprinkle mini marshmallows evenly across the surface. Be generous—this is the part everyone looks forward to.
🔥 Step 5: Bake
Bake at 375°F (190°C) for 20–25 minutes, or until the marshmallows are puffed and lightly golden brown. Watch closely near the end—marshmallows toast fast!
Optional: Broil for 1–2 minutes for extra toasty tops, but don’t walk away. Trust us on this.

Make It Your Own: Variations to Try
This classic is delicious as-is, but if you’re in the mood to get creative, here are a few spins:
🍯 1. Add a Pecan Crumble
Mix chopped pecans with brown sugar, cinnamon, flour, and melted butter to create a crunchy base layer under the marshmallows.
🍠 2. Roasted Sweet Potatoes
Roast instead of boil for deeper flavor. Just cube, toss with a little oil, and bake at 400°F until soft and caramelized before mashing.
🍊 3. Citrus Zest Boost
Add a bit of orange zest to the mash for a subtle zing that balances the sweetness beautifully.
🥥 4. Coconut Love
Add shredded coconut to the marshmallow topping or even mix it into the mash. It adds a sweet, tropical hint that plays well with the dish.
A Personal Slice of Sweet Potato Story
When I was little, I thought sweet potato casserole was dessert pretending to be a side dish—and I was absolutely right. At every holiday dinner, I’d nudge it onto my plate under the radar, next to the turkey and green beans, pretending I wasn’t just waiting for those golden, gooey marshmallows to cool.
And now? I’m the one bringing it to the table every year. Except now I double the marshmallow layer—because the people have spoken.
Make-Ahead and Storage Tips
One of the best parts of this dish? It’s incredibly make-ahead friendly.

- Thaw in the fridge, top with marshmallows, and bake as usual.

Common Questions (and Real Answers)

Absolutely. Just make sure to drain them well and skip any added syrup.
❓ Is this recipe vegan-friendly?
Yes, with a couple of swaps: plant-based butter and vegan marshmallows will do the trick.
❓ Can I make it less sweet?
Sure thing. Reduce the brown sugar or skip it entirely—the marshmallows provide plenty of sweetness on their own.
