This slow cooker 4-ingredient brown butter sweet potatoes recipe is my no-fuss answer to holiday chaos, and it comes straight from how my grandmother used to treat sweet potatoes on the farm. She loved the nutty, toasty flavor of browned butter and the way it wrapped itself around tender orange chunks, turning them into something that tasted like sunshine and Sunday supper all at once. I’ve simply traded her old enamel roasting pan for a slow cooker, so you can tuck this side dish in a corner of the counter and forget about it while you tend to the turkey, ham, or whatever else is on your table. The result is a glossy, amber-brown butter glaze that pools around soft, melting sweet potatoes, with tiny toasted milk solids clinging to the edges just like in her holiday kitchen.
Serve these brown butter sweet potatoes right from the slow cooker on your holiday table, where they’ll stay warm and cozy beside roast turkey, baked ham, or a pot roast. They’re especially nice with something savory and salty—think green bean casserole, simple buttered peas, or a crisp salad with a tangy vinaigrette to cut through the sweetness. Spoon some of the syrupy brown butter from the bottom of the crock over each serving for extra shine, and if you like, pass a small dish of flaky salt at the table so folks can sprinkle a pinch on top for contrast.
Slow Cooker Brown Butter Sweet PotatoesServings: 6
Ingredients
3 pounds sweet potatoes, peeled and cut into 1 1/2-inch chunks
1/2 cup (1 stick/113 g) unsalted butter
1/2 cup packed light brown sugar
1 teaspoon kosher salt
Directions
Peel the sweet potatoes and cut them into roughly 1 1/2-inch chunks so they cook evenly. Pile them into a 4- to 6-quart slow cooker, spreading them out in an even layer.
In a medium light-colored saucepan or skillet, melt the butter over medium heat. Let it bubble, stirring or swirling the pan often, until the foam subsides and the milk solids at the bottom turn a deep golden brown and smell nutty, 5 to 8 minutes. Watch closely so it doesn’t burn.
Remove the pan from the heat as soon as the butter is browned. Immediately stir in the brown sugar and salt until you have a smooth, glossy, amber-colored mixture. It will sizzle and thicken slightly as you stir.
Pour the warm brown butter mixture evenly over the sweet potatoes in the slow cooker. Use a spatula or spoon to gently toss and coat all the pieces so every chunk gets a bit of that nutty sweetness.
Cover the slow cooker with the lid and cook on LOW for 4 to 5 hours, or on HIGH for about 2 to 2 1/2 hours, until the sweet potatoes are very tender when pierced with a fork but still hold their shape.
Once tender, gently stir the sweet potatoes in the slow cooker so the browned bits and syrupy sauce from the edges and bottom coat everything. Some pieces will get a speckled, dark brown crust from the toasted milk solids and caramelized sugar, and the glaze will look thick and bubbly around the edges.
Taste and adjust the seasoning if needed, adding a pinch more salt if you want the sweetness to pop. Serve the sweet potatoes straight from the slow cooker, spooning extra brown butter syrup from the bottom over the top just before bringing them to the table.
Variations & Tips
For a slightly spiced version, add 1 teaspoon ground cinnamon or pumpkin pie spice to the brown sugar before stirring it into the hot browned butter. If you like a brighter flavor, stir in 1 to 2 teaspoons of fresh orange zest with the brown sugar and salt to give the glaze a gentle citrus lift. To lean a bit more savory, finish the cooked sweet potatoes with a few grinds of black pepper or a sprinkle of flaky sea salt right before serving. If you prefer a richer, almost candied texture, let the sweet potatoes cook on LOW for an extra 30 minutes with the lid slightly ajar, which allows more moisture to escape and thickens the glaze. And if you need to stretch the dish for a bigger crowd, you can add up to 1 more pound of sweet potatoes and increase the butter and brown sugar to 3/4 cup each, keeping the salt at about 1 1/2 teaspoons and adding a little extra cooking time as needed.
