Why We Love This Slow Cooker Sweet Potato Casserole

Once we realized we could make our favorite sweet potato casserole in a crockpot, we were sold. This is the way we make it every holiday now, and it couldn’t be easier or tastier!

  • Easy. This classic sweet potato casserole is a breeze to make in the Crockpot, and it will free up your oven for the rest of the meal. It’s a great alternative to oven-baked and so simple to prep.
  • Sweet. The combination of sweet potatoes, brown sugar, cinnamon, vanilla, and mini marshmallows makes this casserole irresistible.
  • Crunchy. Pecans add a nutty flavor and delightful crunch to this casserole.

Variations on Slow Cooked Sweet Potato Casserole

There are so many ways to jazz up this classic casserole. Try swapping the marshmallows for a pecan streusel topping by combining chopped pecans, brown sugar, melted butter, and cinnamon. Sprinkle this over the casserole during the last hour of cooking.

You could also drizzle the casserole with a maple syrup glaze or add a pinch of nutmeg to the potatoes as they cook for even more holiday flavor.

For a more savory casserole, add herbs like rosemary, thyme, and sage to the sweet potatoes and sprinkle them with grated cheddar or Parmesan cheese during the last hour of cooking.

How long does it take to cook sweet potato casserole in a crockpot?

This side dish takes 3 ½-4 hours on a high setting, or on low for 6-8 hours. Just set it to go while you are prepping the rest of the meal and your Thanksgiving dinner will be a breeze to make!

Do you need to peel the sweet potatoes before making casserole?

Yes, it’s best to peel the sweet potatoes as the skins can be quite tough and chewy even when cooked. Cut them into similar-sized pieces so that they cook evenly.

Can I substitute canned sweet potatoes for fresh sweet potatoes?

Canned or thawed frozen sweet potatoes can be used in this recipe.

Should sweet potato casserole be firm?

Sweet potato casserole should be set and firm, not loose and runny.

Why does sweet potato casserole get watery?

Sweet potatoes tend to absorb water, so if you boil them before making the casserole, they will release that water as they bake/cook, making the casserole watery. We avoid this by cooking them from raw in a crockpot.

How do you thicken up sweet potato casserole?

If you prefer a thicker casserole, add 2-3 tablespoons of flour to the sweet potatoes to help them thicken up as they cook. You can also stir in some cornstarch towards the end of the cook time.

Can I make this ahead of time?

Yes! You can prep the whole dish the night before and keep covered and refrigerated until ready to cook. Once cooked, the casserole will keep well for up to 5 days in the fridge.
