How To Make A Sweet Potato Casserole
These step-by-step photos and instructions help you visualize how to make a sweet potato casserole with marshmallows. See the recipe box below for ingredient amounts and full recipe instructions.
- Start by baking 1 large or 2 small sweet potatoes. Alternatively, you can use canned sweet potatoes; just drain and rinse them under cool water. Once baked or drained, mash the sweet potatoes and transfer them to a bowl, aiming for about 1 cup of mashed sweet potatoes.
- In a separate small bowl, create your spice blend by combining brown sugar, ground cinnamon, nutmeg, allspice, ginger, ground cloves, and a pinch of salt.
- Add this blend to the mashed sweet potatoes, stirring thoroughly to combine.
- Next, incorporate one lightly beaten egg into the sweet potato mixture.
- Prepare a 5×5 inch baking dish by lightly buttering it, then pour the sweet potato mixture into the dish. Evenly sprinkle pecans over the top. Bake the casserole in a preheated oven for 15 minutes.
- After 15 minutes, take the casserole out of the oven. Add marshmallows to the top and return it to the oven.
- Bake for an additional 10 minutes, or until the marshmallows are golden and puffy.
Expert Tips
- Mash Thoroughly: Make sure the sweet potatoes are well-mashed for a smooth and creamy texture.
- Customize the Spices: Adjust the spices to match your taste. Add more or less of your favorites to make the dish just right for you.
- Let It Cool: Allow the casserole to rest for a few minutes after baking. It will be very hot, and cooling slightly ensures the best texture and flavor when served.

I unexpectedly found myself alone for Thanksgiving so instead of feeling “blah” I decided to “fancy up” my holiday meal. It helped that I didn’t have to scale down our family favorites but could use recipes like this Mini-Sweet Potato casserole. The blend of spices was excellent. I’d never had both marshmallows AND pecan toppings in the same dish but this worked out quite nicely! The best of both worlds.
Thank you for sharing this! I’m so glad the recipe helped make your holiday special. I agree, the marshmallow and pecan topping is such a treat—so happy you enjoyed it!
Left off the marshmallows and added dried cranberries! Perfect for me.
Sounds wonderful! I’m so happy you enjoyed it.
Made this recipe. it was really good. I’m diabetic so I substituted monk brown sweeter for the brown sugar. Since I have to watch my carbs I divided into 2 ramekins. Next time will divide into 3 and use a little less of the cloves.
