How to Make Crockpot Sweet Potatoes With Marshmallows
- Prep your crockpot: Spray an 8-quart slow cooker with non-stick spray (trust me, it makes cleanup a breeze).
- Combine the goodness: Add the sweet potatoes, brown sugar, maple syrup, butter, pumpkin pie spice, and salt. Stir everything together so every cube of potato gets a sweet coating.
- Slow cook to perfection: Cover and cook on high for 4 hours, until the sweet potatoes are fork-tender and your kitchen smells like fall heaven.
- Add the marshmallow magic: Five minutes before serving, lift the lid and sprinkle those mini marshmallows on top. Pop the lid back on just until they melt — about 3–5 minutes.
- Serve & enjoy: Drizzle some of that buttery syrup from the bottom if you’d like an extra touch of sweetness (and who wouldn’t?).

Mounia’s Tips for the Perfect Sweet Potato Casserole
- Don’t skip the salt! It balances out the sweetness beautifully.
- Customize the spices: Swap pumpkin pie spice for cinnamon and nutmeg if that’s what you have on hand.
- Want to get fancy? Add a handful of chopped pecans on top before the marshmallows for a little crunch.
- Double it up: Feeding a crowd? This recipe easily doubles — just make sure your slow cooker can handle it!
And if your sauce looks a little “too saucy,” don’t worry — it’s just extra flavor waiting to be spooned over your plate later.
