This 3-ingredient slow cooker candied sweets recipe is the kind of low-effort, high-reward dessert that feels almost too easy. You literally toss fresh peeled whole sweet potatoes into the slow cooker, sprinkle on brown sugar, dot with butter, and let the magic happen while you go live your life. A few hours later, you have tender, caramel-y sweet potatoes swimming in a glossy syrup that tastes like the best part of sweet potato casserole—without turning on the oven. It’s perfect for busy weekends, holiday dinners, or any night you want something cozy and a little decadent without a lot of dishes.
Serve these candied sweet potatoes straight from the slow cooker with plenty of the syrup spooned over the top. They’re amazing alongside roast chicken, pork chops, or a simple baked ham, but they also double as a dessert with a scoop of vanilla ice cream or a dollop of whipped cream. For brunch, tuck them next to scrambled eggs and bacon for a sweet-and-savory spread. If you have leftovers, slice them up and rewarm with extra sauce to spoon over oatmeal, yogurt, or pancakes the next morning.
3-Ingredient Slow Cooker Candied SweetsServings: 6
Ingredients
3 pounds fresh sweet potatoes, peeled and left whole (small to medium size works best)
1 cup packed light or dark brown sugar
1/2 cup (1 stick) unsalted butter, cut into pieces
Directions
Peel the sweet potatoes and leave them whole. If any are very large, you can trim the ends or cut them in half crosswise so they fit in the slow cooker, but aim to keep them as large, intact pieces.
Arrange the peeled whole sweet potatoes in a single snug layer in the bottom of a 5- to 6-quart slow cooker. The potatoes should be touching but not crammed so tightly that the lid won’t close.
Sprinkle the brown sugar evenly over the tops of the sweet potatoes, letting some fall down around the sides so it reaches the bottom of the slow cooker.
Dot the butter pieces evenly over the brown sugar and sweet potatoes, distributing them across the surface so they melt down into a syrup as they cook.
Cover the slow cooker with the lid and cook on LOW for 5 to 6 hours, or on HIGH for 2 1/2 to 3 hours, until the sweet potatoes are very tender when pierced with a fork and the brown sugar and butter have formed a thick, glossy syrup.
Once tender, carefully spoon some of the syrup from the bottom of the slow cooker over the tops of the sweet potatoes. Let them sit on WARM for 10 to 15 minutes to allow the syrup to cling a bit more, if you have time.
Serve the sweet potatoes whole or sliced, spooning plenty of the warm syrup over each portion. Turn the slow cooker to WARM if you’re serving over a longer period, and keep the lid mostly on to prevent the syrup from drying out.
Variations & Tips
For extra flavor without adding more ingredients, you can use dark brown sugar for a deeper, molasses-like sweetness. If you’re cooking for a crowd and need to stretch the recipe, add up to 4 pounds of sweet potatoes and increase the brown sugar to 1 1/4 cups and butter to 3/4 cup, making sure your slow cooker is large enough for the whole pieces to sit mostly in a single layer. To make this dairy-free, swap the butter for a plant-based buttery spread or refined coconut oil (note that coconut oil will add a subtle coconut flavor). You can also lightly salt the finished dish to balance the sweetness, especially if you’re serving it as a side with savory mains. For meal prep, cook the sweet potatoes as directed, cool them completely in the syrup, then refrigerate in an airtight container for up to 4 days; reheat gently on the stovetop or in the microwave, basting with the syrup. For food safety, always wash and peel the sweet potatoes before cooking, trim any bruised or damaged spots, and avoid leaving the cooked potatoes at room temperature for more than 2 hours. If using the WARM setting on your slow cooker for serving, keep it under 4 hours and make sure the lid is mostly on so the food stays above 140°F. Discard any leftovers that have sat out too long, and always reheat leftovers until steaming hot throughout before serving.
