(Maple syrup in the topping goes SO well with the sweet potatoes!)

Ingredients in a sweet potato casserole

How to make a sweet potato casserole

Start by preparing the sweet potato filling. Cook the sweet potatoes in the oven or in the microwave, then scoop out the potato and add it to a food processor with some vegan butter, salt, cinnamon and nutmeg.

Puree until smooth. If you like it a little chunky, just pulse it a few times. You can also just use a potato masher and do this step by hand if you prefer.

Spread the mixture into a baking dish. 8×8 inches, 13x8inches, or a round 8-inch dish all work fine. Mix the topping ingredients together together in a bowl using a fork or your fingers, then spread it ontop of the potatoes.

Bake the casserole at 350 degrees F for 35-40 minutes until the top is golden brown.

Can I substitute squash for sweet potato?

Yes! If you love squash and prefer to use it in this recipe, simply replace the sweet potatoes with one large roasted butternut squash. You can use this guide on how to cook butternut squash to help you prepare the squash for this dish.

Tips for making this recipe perfectly

  • Taste the sweet potato before adding it to the baking dish. Some sweet potatoes are sweeter and more flavourful than others, so taste the mashed potato mixture and adjust any seasoning if needed. Some people like adding a bit of maple syrup or brown sugar directly to the potatoes.
  • Use your hands to mix the crumble topping together. It’s easier than using a fork to get everything mixed up.
  • Don’t use a baking dish that’s too big. You’ll end up with a thin layer of potatoes. This casserole is best with a nice thick layer.
  • If your sweet potatoes seem a bit small, use 6-7 potatoes for this recipe.
