Instructions
This sweet potato casserole is an easy recipe that’s made with simple ingredients! You’re essentially just mixing everything up into your slow cooker, then letting it work its magic.
Scroll to the recipe card below for the full instructions and ingredient amounts.
- In a small bowl, combine sugar, water, cinnamon, and pumpkin pie spice.
- Add the diced sweet potatoes into a greased slow cooker, then pour the sugar and butter mixture over the top of the sweet potatoes. Stir to combine.
- Cover the sweet potato mixture and cook on high for 3-4 hours or on low for 7-8 hours.
- Once the potatoes are cooked, use a potato masher or hand mixer to mash the potatoes. Stir in the eggs, cover, then cook for another 2 hours.
- Remove the lid, top with marshmallows and chopped pecans, then cover again and let the marshmallows soften slightly.
Tips and Notes
- Peel the potatoes. Before chopping, I recommend using a potato peeler to remove the skin from the raw sweet potatoes. When cooked, the skin can take on an unpleasant chewy texture. This dish is better without it!
- Dice the potatoes evenly. Be sure that all of the potatoes are cut into relatively even 1-inch pieces. This ensures that they all cook at the same rate, but don’t over-cook in the slow cooker.
- Grease the slow cooker insert. A light layer of cooking spray should do the trick! This just prevents the sweet pototoes from sticking to the bottom of the ceramic insert.
- Adjust to taste. Any of the spices and sugar can be adjusted to suit your tastes. As written, this casserole smells similar to a pumpkin pie and tastes very sweet, like a dessert. If you want something a little less sweet, feel free to play around with the sweetener amounts.
- The color may vary. The sweet potato casserole in my photos is dark in color because we used dark brown sugar and the full amount of spices. If you use a lighter kind of brown sugar or less of the spices, then your casserole will look different. That’s okay!

Frequently Asked Questions
Why Does Sweet Potato Casserole Get Watery?
The water content of the potatoes you use can affect the texture of your finished dish.
If you notice your sweet potatoes are a little bit more watery than you prefer, simply let them cook in the crockpot with the lid off for a few minutes to let some excess water evaporate.
Keep in mind that the mixture will also thicken up as it cools!
How Do You Thicken a Sweet Potato Casserole?
If you want to make sure that your casserole is nice and thick, try adding a couple tablespoons of flour to the crockpot before cooking.
This will help absorb any moisture that the potatoes release during the slow cooking process.
