The Ingredients

This recipe uses simple, affordable ingredients that come together beautifully.

4 medium whole raw unpeeled sweet potatoes, scrubbed – For tender, sweet, earthy potatoes.
3 tablespoons unsalted butter, cut into small pieces – For richness and a glossy sauce.
⅓ cup packed brown sugar – For sweetness and caramelization.
1 teaspoon ground cinnamon – For warmth and depth.

Step-by-Step Instructions

Step 1: Scrub the Sweet Potatoes

Scrub the whole sweet potatoes well under running water, leaving the skins on. Pat them dry with a clean towel. Do not peel or cut them.

Pro Tip: Leaving the skins on adds texture and nutrients—and they’re perfectly edible.

Step 2: Arrange in the Slow Cooker

Place the whole raw unpeeled sweet potatoes in a single layer on the bottom of the slow cooker. They should fit snugly; it’s okay if they touch but try not to stack them.

Pro Tip: A single layer ensures the sweet potatoes cook evenly.

Step 3: Add the Toppings

Sprinkle the brown sugar evenly over the tops of the sweet potatoes. Scatter the butter pieces over the sugar, then sprinkle the cinnamon over everything.

Pro Tip: Distribute the toppings evenly so every sweet potato gets coated.

Step 4: Cook Low and Slow

Cover the slow cooker with the lid and cook on LOW for 6 to 7 hours, or on HIGH for 3 to 4 hours, until the sweet potatoes are very tender when pierced with a fork and starting to slump and release juices.

Pro Tip: Don’t lift the lid! Every time you open the slow cooker, you lose heat and add cooking time.

Step 5: Split and Sauce

Once cooked, carefully use tongs to gently squeeze each sweet potato to loosen the insides, then split them open lengthwise right in the slow cooker or on serving plates. Stir the buttery brown sugar and cinnamon mixture in the bottom of the slow cooker to combine with the sweet potato juices, forming a simple sauce.

Pro Tip: Be gentle when squeezing—the sweet potatoes are very tender.

Step 6: Serve and Enjoy

Spoon the warm sauce over the opened sweet potatoes and serve immediately, enjoying the soft flesh and edible skins together.

Pro Tip: Serve with a dollop of whipped cream or a scoop of vanilla ice cream for an extra-special treat.
