This gluten free vegan sweet potato casserole is the perfect side dish when you’re craving something warm, cozy and substantial. You can (and should!) serve this dish year round, but I think it would work particularly well as a vegan side dish at a Thanksgiving or Christmas dinner.
Gluten Free Vegan Sweet Potato Casserole – Key Ingredients
The star of this casserole is the crispy crumbly topping made from fresh sage leaves, chives, garlic, pecans, and oat flour (or feel free to substitute whatever flour you prefer).
I think fresh sage is the perfect herb to compliment the other flavours in this casserole. The sage gives this dish a woodsy autumnal flavour that is comforting and so delicious. There really isn’t any substitution for fresh sage in this recipe. Dried sage just doesn’t offer the same flavour so I urge you to go for the fresh stuff 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 to a large crowd, perhaps 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’m suspect both your herbivore and carnivore guests will enjoy this dish.
You can prepare this dish up to a few days in advance and reheat in the oven before serving. Leftovers are delicious and can be reheated in the oven (or toaster oven). In a pinch you could reheat this casserole in the microwave, but the crumb topping will lose some of it’s crispiness.
