Slow Cooker Sweet Potato Casserole
Slow Cooker Sweet Potato Casserole is a cozy, set-it-and-forget-it side dish that tastes like fall in a crockpot. It’s made with creamy, mashed sweet potatoes mixed with brown sugar, butter, vanilla, and warm spices, then topped with a crunchy pecan streusel that cooks right on top. The slow cooker keeps it hands-off, frees up oven space during the holidays, and makes serving super easy, just scoop it out straight from the pot.
I grew up on the classic marshmallow-topped version, but I’ve gotta say, this one’s better. It’s like dessert disguised as a side dish. I love that it’s all in one pot, too.
If you’re looking for more holiday side dishes, try these too: my fresh green bean casserole, Hawaiian dinner rolls, or this herb and apple stuffing. They are all amazing!
