Ingredient Notes

A great Slow Cooker Sweet Potato Casserole is all about balance and texture. Here’s what you’ll need and why it matters.

The Foundation: Sweet Potatoes
The star! Look for firm, vibrantly colored sweet potatoes with smooth skin. Skip any with bruises or sprouting. I like medium-sized, orange-fleshed varieties for their rich flavor and creamy texture.

Aromatics and Spices
Cinnamon and nutmeg offer classic warmth, while a pinch of salt keeps sweetness in check. For extra depth, try a dash of ground ginger or cardamom. Want to experiment? Add a hint of maple syrup for a woodsy twist.

Creamy Mix-Ins
Butter and either heavy cream, evaporated milk, or coconut milk give the mash a lush, spoonable consistency. If you want a lighter dairy-free version, use oat milk and vegan butter.

Sweetness
Brown sugar delivers that signature caramel note but can be swapped for coconut sugar or maple syrup if preferred. Adjust the sweetness to your taste a little goes a long way!

Eggs (Optional)
Some recipes add an egg for structure, making the casserole a bit more set. If you prefer a lighter, more scoopable dish or need egg-free, just skip.

Topping: Crunch and Flair
Classic toppings include chopped pecans, mini marshmallows, or even a brown butter streusel. For allergy-friendly, swap pecans for sunflower seeds or leave nuts off entirely. My secret: toast the pecans before adding for extra crunch.

How to Make Slow Cooker Sweet Potato Casserole

Preparation: Setting Up for Slow Cooker Success

Start by peeling and chopping your sweet potatoes into uniform chunks this ensures even cooking. A 6-quart slow cooker is ideal, giving the potatoes space to cook down without overflowing. Coat the insert with nonstick spray for easy cleanup.

Gather and measure your spices, brown sugar, and cream. Chop toasted pecans and set out marshmallows or your favorite topping. Having everything ready before you start makes assembling this Slow Cooker Sweet Potato Casserole a breeze.

Cooking Process: Step-by-Step for Perfect Texture

2. Pour in cream or chosen liquid. Stir gently to coat the potatoes.
3. Set slow cooker on HIGH for 3-4 hours or LOW for 6-7 hours. Potatoes are done when fork-tender and soft.
4. Mash directly in the slow cooker. Use a potato masher or hand mixer for ultra-smooth results.

Pro Tip: Don’t overcook. Once the potatoes are fork-tender, turn the slow cooker to warm. Overcooking can lead to watery mash.
