This slow cooker 3-ingredient cinnamon apple sweet potatoes recipe is the kind of sweet side dish kids actually beg for every weekend. It’s cozy Midwestern comfort food at its simplest: just sweet potatoes, apples, and cinnamon sugar doing their thing low and slow until everything turns soft, caramelized, and sticky with glaze. Versions of this idea show up everywhere from church potlucks to holiday buffets, but here we strip it down to three pantry staples and let the slow cooker do the work. The result is a warm, fragrant side that tastes like dessert but sits happily next to roasted chicken, pork, or a simple weeknight meatloaf.
Serve these cinnamon apple sweet potatoes straight from the slow cooker or transfer them to a foil-lined baking sheet to thicken and caramelize further in a hot oven before bringing them to the table. They pair beautifully with roasted or grilled pork chops, baked ham, rotisserie chicken, or simple sausages. For brunch, tuck a scoop next to scrambled eggs and bacon, or spoon them over Greek yogurt with a handful of toasted nuts. If you lean dessert, add a dollop of whipped cream or vanilla ice cream and an extra sprinkle of cinnamon for a quick, almost cobbler-like treat.
Slow Cooker 3-Ingredient Cinnamon Apple Sweet PotatoesServings: 6
Ingredients
2 1/2 pounds sweet potatoes, peeled and cut into 1-inch cubes
3 large firm apples (such as Honeycrisp or Granny Smith), cored and sliced into 1/2-inch wedges
3/4 cup cinnamon sugar (store-bought or homemade: 3/4 cup granulated sugar mixed with 2–3 teaspoons ground cinnamon)
Directions
Prepare the slow cooker and baking sheet: Line a rimmed baking sheet with aluminum foil and set it aside for later. Lightly coat the inside of a 4- to 6-quart slow cooker with cooking spray or a thin film of neutral oil to help prevent sticking and make cleanup easier.
Layer the sweet potatoes: Add the cubed sweet potatoes to the bottom of the slow cooker, spreading them into an even layer so they cook at the same rate. The cubes should be roughly the same size, about 1 inch, so they soften evenly without turning to mush.
Add the apples: Arrange the apple slices over the sweet potatoes in an even layer. The apples will soften more quickly and release juices that help create the sticky cinnamon glaze, so having them on top allows that liquid to drip down through the sweet potatoes.
Sprinkle on the cinnamon sugar: Evenly sprinkle the cinnamon sugar over the apples and sweet potatoes, making sure to cover as much surface area as possible. Do not stir; leaving the layers intact helps the sweet potatoes steam and then slowly bathe in their own juices and the melting cinnamon sugar.
Slow cook until tender and glossy: Cover the slow cooker with the lid and cook on HIGH for 2 1/2 to 3 hours or on LOW for 5 to 6 hours, until the sweet potatoes are very tender when pierced with a fork and the apples are soft and silky. As they cook, the sugar will dissolve into the juices from the apples and sweet potatoes, forming a glossy cinnamon glaze.
Gently toss to coat: Once everything is tender, carefully remove the lid and gently toss the sweet potatoes and apples together with a large spoon or spatula, taking care not to mash them. You want bright orange cubes and tender golden apple slices coated in the sticky cinnamon glaze with visible flecks of spice.
Optional caramelizing step on foil-lined sheet: For the texture shown in the description—soft, caramelized edges with a slightly thicker glaze—transfer the sweet potatoes and apples, along with all the syrupy juices, onto the prepared foil-lined baking sheet. Spread into an even layer. Place under a preheated broiler on the middle rack for 5 to 8 minutes, watching closely, until the glaze bubbles and darkens slightly in spots and a bit of steam rises off the pan.
Rest briefly and serve: Let the pan sit for 5 minutes so the glaze can thicken slightly as it cools. Serve warm as a sweet side dish, spooning both the cubes of sweet potato and the tender apple slices onto each plate and drizzling with any extra cinnamon glaze from the pan.
Variations & Tips
Because this recipe is intentionally built around three ingredients, think of variations as small tweaks rather than additions that change its essential simplicity. For a slightly deeper flavor without adding more ingredients, choose a mix of sweet potatoes and garnet yams, which caramelize beautifully. Swap the apple variety to change the character: tart Granny Smiths keep their shape and balance the sweetness, while Honeycrisp or Gala make the dish taste closer to apple pie. If you prefer a drier, more roasted texture, extend the broiler or oven time on the foil-lined baking sheet by a few minutes, stirring once so more surfaces caramelize; just watch carefully to avoid burning the sugar. To make it ahead, cook fully in the slow cooker, cool, and refrigerate in a covered dish; reheat on the foil-lined baking sheet in a 375°F oven until hot and lightly caramelized again. If you ever decide to move beyond the three-ingredient rule, a pinch of salt and a splash of vanilla or a pat of butter stirred in at the end will make the flavors taste even more rounded and bakery-like, but the base recipe truly stands on its own with just the three core ingredients.
