This Sweet Potato Casserole has turned into our family's must-have holiday dish. The smooth sweet potatoes mixed with spicy cinnamon and rich brown sugar work wonders together. When the marshmallows get that perfect golden color and the pecans become crunchy, everyone at my table knows they're in for a treat.
Easy But Impressive
What gets me is how regular stuff turns into something so darn good. Each part brings something special - from the velvety potatoes to the crunchy nuts and sticky marshmallows crowning it all. And I can make most of it before the big day, which makes holiday cooking way less stressful.

My Kitchen Secrets
You'll taste the difference with fresh sweet potatoes. I make sure they're super well-drained to keep the casserole from getting soggy. Sometimes I don't mash them completely smooth for a bit of texture, and I'm careful about spreading those marshmallows evenly for the prettiest top.
Mix It Up
Maybe try a crumbly streusel on top next time, or add a splash of bourbon for extra flavor. When things seem too sweet, I'll skip marshmallows and go heavy on the pecan topping instead. Friends who can't eat nuts love it when I swap in some toasted coconut flakes.
Plan Ahead
The main potato mixture can sit in your fridge for two days before the big event, just keep the toppings separate until you're ready to bake. Don't forget to let it warm up a bit before adding marshmallows and nuts. Any leftovers taste great for days afterward - perfect for quick snacks.
Soul-Warming Goodness
This casserole just makes gatherings feel more like home. Whether it's part of our big Thanksgiving spread or brightening up a normal weekend meal, it always gets people smiling. That perfect mix of sweet and savory with all those different textures makes everyone come back for seconds.

Frequently Asked Questions
- → Can I make this casserole ahead of time?
For sure, you can cook the sweet potatoes up to 3 days early. Keep them in the fridge until you're set to mash and put everything together. Just pop the toppings on right before the last bake.
- → What can I substitute for pecans?
Try walnuts or cashews as pecan alternatives. The nuts give a lovely crunch, but you can leave them out entirely if you want or have nut allergies.
- → How do I know when the casserole is done?
Your dish is finished when the marshmallows look golden and puffy, usually after about 20-25 minutes in the oven. The sweet potato mix should be hot all the way through.
- → Can I use regular marshmallows instead of mini ones?
Standard marshmallows work great in this dish. They'll create bigger, fluffier topping sections. Just lay them out in one layer over the pecans.
- → How should I store leftovers?
Wrap the dish with foil and keep it in the fridge for up to 4 days. Warm up portions in the microwave, though the marshmallows won't be as fluffy as when first baked.
