Ingredients

For this Sweet Potato Casserole with Marshmallows, I list the core ingredients first to keep the process simple and friendly. My goal is a creamy base with a playful, toasty crown. Exact quantities are at the bottom of the article and in the printable version, so you can prep now and bake later.

I’ll share easy tweaks for dairy-free, sugar-conscious kitchens and for those who crave a little extra crunch. This way, you can tailor the dish without losing the familiar comfort it brings.

Core ingredients

• 4 large sweet potatoes, peeled and cubed — the creamy, comforting base that mashes to silky texture.
• ¼ cup butter, softened — adds richness and helps the mash come together smoothly.
• ¼ cup brown sugar — brings a warm caramel note that isn’t too sweet.
• 2 tbsp maple syrup or honey — deepens sweetness with a gentle floral ribbon.
• ¼ cup milk (or cream for extra richness) — adds silkiness and helps the flavors blend.
• 1 tsp vanilla extract — lifts the potato flavor with a soft aroma.
• ½ tsp cinnamon — warm spice that screams holidays.
• ¼ tsp nutmeg — a subtle whisper of spice that complements cinnamon.
• Pinch of salt — balances sweetness and heightens flavor.
• ½ cup chopped pecans — a toasty crunch and nutty aroma on top.
• 2 cups mini marshmallows — the crown that toasts into a gooey, golden finish.

Optional tweaks and substitutions

• Dairy-free option: Use ¼ cup dairy-free butter substitute and ¼ cup almond or coconut milk.
• Nut-free version: Omit pecans or swap with toasted pepitas for crunch.
• Sugar dynamics: Try coconut sugar for a deeper caramel tone; keep the ratio similar.
• Flavor twists: A pinch of ground ginger or a splash of orange zest brightens the dish.
• Marshmallow variations: Use dairy-free mini marshmallows if needed.
• Make-ahead tip: Measure ingredients in advance and assemble later to save time on cooking day.

How to Make Sweet Potato Casserole with Marshmallows

Step 1: Preheat, prep, and set up

Step 1 details and tips

I preheat the oven to 375°F and lightly grease a 9×13 dish. I gather the creamy base ingredients so nothing stops the flow of the day.

Little prep goes a long way, so measure and line up what you need. This keeps the kitchen calm when time is tight.

Step 2: Boil and mash the sweet potatoes

Step 2 details and tips

Boil the potatoes until tender, about 15–20 minutes. Drain well and mash until smooth and silky.

Tips: a pinch of salt in the water keeps the mash bright. If you’re short on time, cut potatoes into chunks for faster cooking.

Step 3: Stir in creaminess and flavor

Step 3 details and tips

Stir in butter, brown sugar, maple syrup, milk, vanilla, cinnamon, nutmeg, and salt until creamy. Taste and adjust sweetness if needed.

This is the moment the kitchen smells like holidays and cozy mornings. Don’t overwork it; gentle mixing is enough.

Step 4: Layer, top with pecans, and prepare

Step 4 details and tips

Spread the potato mixture in the dish. Sprinkle pecans for toasty crunch, then cover with marshmallows.

Tip: light toasting of pecans in a dry pan first boosts aroma. It’s worth the extra minute.

Step 5: Bake until marshmallows toast to a golden finish

Step 5 details and tips

Bake 20–25 minutes until the marshmallows turn golden and gooey. If your oven browns unevenly, rotate the pan halfway.

Watch closely near the end; you want that perfect toasty crown, not a burnt edge.

Step 6: Rest briefly and serve for ultimate gooeyness

Step 6 details and tips

Let the casserole rest about 10 minutes before serving. Resting helps it set and keeps the gooeyness comfy on the first slice.

Serve warm for the best creamy, melt-in-your-mouth finish that kids and grownups adore.

Variations

I love tailoring this Sweet Potato Casserole with Marshmallows to fit different dietary needs or flavor moods. Here are easy, no-fuss tweaks you can make without changing the soul of the dish.

Dairy-free or vegan option

• Swap to a dairy-free butter substitute and plant-based milk (almond, oat, or soy) for the base.
• Choose vegan marshmallows or marshmallows made with agar-agar instead of gelatin.
• For extra richness, use a splash of coconut cream in place of part of the milk.
• Keep the maple syrup and vanilla for warmth, since dairy-free versions don’t dull those notes.

Nut-friendly or nut-free versions

• Omit pecans and substitute with toasted pepitas (pumpkin seeds) or sunflower seeds for crunch.
• If you skip nuts, consider a crispy topping of crushed cornflakes or a light sprinkle of granola for texture.
• Be mindful of cross-contact; use clean utensils and dedicated prep surfaces if allergies are a concern.

Flavor twists (spices, citrus, or liqueur ideas)

• Increase warmth with a pinch more cinnamon and a whisper of ground ginger or allspice.
• Brighten with orange zest or a splash of fresh lemon juice to balance sweetness.
• For a festive kick, stir in a tablespoon of bourbon, brandy, or Grand Marnier before baking.

Make-Ahead Tips for Sweet Potato Casserole with Marshmallows

I love making this dish ahead. It keeps holiday comfort intact on busy days. I also appreciate the little rituals—the mash becoming silky while I breathe and plan the rest of the menu.

Make-ahead workflow

Make-ahead workflow: mash the potatoes and mix flavors a day ahead. This ensures the base is silky when you bake. I love prepping the creamy mash while other dishes simmer; it frees me up later.

Refrigeration and timing

Assemble in the 9×13 dish, top with pecans, refrigerate; marshmallows stay separate until bake. This makes the dish even easier the next day and keeps the marshmallows from getting soggy.

If freezing, freeze unbaked casserole and thaw overnight before baking. This saves a lot of time on the big day.

Reheating to restore creaminess and toast on top

Reheating leftovers at 350°F, covered, for 15–25 minutes until hot. Uncover and broil 1–2 minutes to toast the top. If it looks dry, add a splash of milk to restore creaminess. A quick whisk with a fork can reintegrate any separated cream.

FAQs

What substitutions work best for dairy or sugar preferences in Sweet Potato Casserole with Marshmallows?

For dairy-free needs, swap in a ¼ cup dairy-free butter substitute and plant-based milk. A splash of coconut cream can add richness if you miss the dairy bite. To tweak sugar, reduce the brown sugar by 1–2 tablespoons or use coconut sugar, and opt for vegan marshmallows if needed.

How far in advance can I prepare this dish?

You can mash the potatoes and mix in the flavoring a day ahead. Keep the base covered in the fridge, then assemble with pecans and marshmallows and bake when ready. If you’re short on time, you can even refrigerate the assembled dish for a few hours and bake later.

Can I freeze baked Sweet Potato Casserole with Marshmallows?

Best practice is to freeze unbaked casserole, tightly wrapped, for up to 2–3 months. Thaw in the fridge overnight, then bake as directed and finish with the marshmallows. Freezing baked casserole is possible, but the marshmallow topping may be less fluffy after reheating.

How to achieve the perfect marshmallow toast without burning?

Bake until the marshmallows puff and just start to brown, then rotate the pan halfway for even color. For extra browning, switch to a quick broil for 1–2 minutes, watching it closely. If you’re panicking about scorching, keep the edges shielded with foil for a gentle, even toast.

Are there crowd-pleasing, kid-friendly tweaks for this recipe?

Yes. Omit nuts or swap with toasted pepitas for a crunch kids usually love. Add an extra handful of marshmallows for a sweeter crown, or keep spices mild and let little helpers dollop the topping. Let kids sprinkle a light graham-cracker crumble for a fun, interactive finish.
