This 3-ingredient slow cooker whipped sweet potato mash is my secret weapon on nights when I’m juggling work emails, homework help, and figuring out what’s for dinner. I don’t know how three things make something this rich and velvety, but my whole family literally scrapes the bowl clean every time. The slow cooker does all the work, turning simple peeled sweet potato chunks into a creamy, buttery mash that tastes like it took way more effort than it actually did. It’s comfort food with almost no hands-on time, which makes it perfect for busy weeknights, holidays, or any time you want a cozy side without hovering over the stove.
Serve this whipped sweet potato mash piled high in a warm bowl with an extra pat of butter melting over the top. It’s perfect alongside roasted chicken, pork chops, meatloaf, or a simple pan-seared steak. I also love it with green beans or a crisp salad to balance the sweetness. For holidays, it slides right onto the table next to turkey, ham, or pot roast, and the leftovers are amazing with a fried egg on top for breakfast.
3-Ingredient Slow Cooker Whipped Sweet Potato Mash
Servings: 6

Ingredients
3 pounds sweet potatoes, peeled and cut into 1 1/2-inch chunks
6 tablespoons unsalted butter, plus more for serving if desired
1 cup heavy cream
1 teaspoon kosher salt (optional, to taste)
Freshly ground black pepper (optional, to taste)
Directions
Add the peeled sweet potato chunks to the insert of a 4- to 6-quart slow cooker, spreading them into an even layer so they cook evenly.
Pour the heavy cream evenly over the sweet potatoes, then dot the top with the 6 tablespoons of butter. Sprinkle with the salt, if using.
Cover and cook on HIGH for 3 to 3 1/2 hours or on LOW for 6 to 7 hours, until the sweet potatoes are very tender and easily pierced with a fork. You should see some steam when you lift the lid and the cream and butter will look pooled and steamy around the potatoes.
Turn off the slow cooker or switch it to WARM. Using a potato masher, mash the sweet potatoes right in the slow cooker until mostly smooth and the butter and cream are incorporated.
For an extra velvety texture, use a hand mixer on LOW speed directly in the slow cooker to whip the sweet potatoes until they are light, fluffy, and glossy. This is where the magic happens and everything turns rich and silky.
Taste and adjust seasoning with more salt and a few grinds of black pepper if you like. If the mash seems too thick, add a splash more warm cream and whip again until it reaches your desired consistency.
Swirl the top with a spoon to create soft peaks, then add an extra pat or two of butter on top so it melts into the warm mash. Serve straight from the slow cooker on the WARM setting to keep it hot for the table.
Variations & Tips
To lighten things up a bit, you can swap half of the heavy cream for whole milk or evaporated milk; the texture will still be creamy, just slightly less rich. For a hint of savory depth, toss in 1 to 2 cloves of minced garlic with the sweet potatoes before cooking, or stir in a small handful of grated Parmesan at the end. If you want a touch of sweetness, add 1 to 2 tablespoons of maple syrup or brown sugar when you mash. For a make-ahead option, cook and whip the sweet potatoes a day in advance, cool completely, then refrigerate in the slow cooker insert; reheat on LOW, stirring occasionally and adding a splash of cream if needed. You can also finish the mash with a sprinkle of smoked paprika, chopped fresh herbs (like chives or parsley), or toasted pecans on top for a little crunch. If you’re dairy-free, use full-fat canned coconut milk and a rich vegan butter substitute—the flavor will be slightly different but still cozy, creamy, and bowl-scraping good.
