This dairy-free sweet potato casserole hits the spot when you’re craving something warm, cozy, and substantial. It’s an easy and delicious gluten-free, vegan side dish for Thanksgiving or Christmas dinner.
The star of this casserole is the crispy, crumbly topping made from fresh sage leaves, chives, garlic, pecans, and oat flour (or substitute whatever flour you prefer).
Fresh sage is the perfect herb to complement the flavour of sweet potatoes. The sage gives this dish a woodsy, autumnal flavour that is comforting and so delicious. In a pinch, you can substitute 1 teaspoon of dried sage, but do go for the fresh sage if possible.
This sweet potato casserole is so easy to make. Start by preparing the mashed sweet potatoes. My preferred method of cooking sweet potatoes is to cut them into thick slices and bake them in the oven until they’re tender. Alternatively you can boil or steam the sweet potatoes instead.
Once your sweet potatoes are cooked, slip off the skins (you should be able to remove them easily with your fingers). Then you can use a potato masher or a fork to mash them up before transferring them to your baking dish.
All that’s left is to mix up the savoury crumb topping, sprinkle in an even layer on top of the mashed sweet potatoes, and bake.
If you’re serving this gluten-free vegan sweet potato casserole at Thanksgiving or Christmas, go ahead and double or triple the recipe if necessary and just use a larger baking dish (or multiple dishes). Make lots as I suspect both your herbivore and carnivore guests will enjoy this dish.
You can prepare this dairy-free sweet potato casserole up to a few days in advance and reheat in the oven before serving. You can also reheat this casserole in the microwave, but the crumb topping will lose some of it’s crispiness.
