There is sweet potato casserole that is savory as well as sweet. If you are looking for a savory sweet potato casserole, try my Savory Sweet Potato Casserole with Sourdough Bread Crumbs.  As I’m getting older, I find that my taste buds are shifting toward the savory. But I’m getting ready to make Christmas dinner for my family, and they like it sweet! We first discovered sweet potato casserole at a fun dinner theater in Dayton Ohio. It was called sweet potato souffle, and we’ve been big fans ever since! Some other delicious side dishes you should try for your holiday day table include:

The Ingredients for Sweet Potato Casserole:

Typically, one of the major ingredients in a casserole or “souffle” such as this is eggs. Eggs are the perfect ingredient to bind everything else together. You won’t need eggs in this dish! Using a little cornstarch and cooking the casserole a little slower and lower than the original recipe helps.

These are the ingredients you will need to make this sweet potato casserole.

You will need:

(Please see the recipe card below for the full ingredient list with amounts along with the instructions.)

  • canned sweet potatoes (you can choose to cook your own – you will need about 8 medium-sized sweet potatoes)
  • vegan butter
  • brown and white sugar
  • vanilla
  • four
  • salt
  • orange zest
  • cornstarch

Tips and Tricks for Making Sweet Potato Casserole:

  • I use canned sweet potatoes for this dish. It’s easier than cooking and mashing. I’ve tried it both ways and the flavor isn’t improved by baking your own. But if you would like to cook your own, bake about eight medium-sized sweet potatoes. Allow to cool enough to handle, and then scoop out the insides.
  • Drain the canned sweet potatoes well and then mash with a masher or with your hand-mixer. Add the other ingredients with the exception of the topping ingredients.
  • If you are ethically vegan, be aware that some sugar is processed using bone-char. Either use organic sugar or one that is labeled vegan if that is your concern.
  • Pour into a prepared 9×13 casserole dish and smooth the top. It will be the consistency of a very thick cake batter.

  • Combine the ingredients for the topping and mix well. I use the same beaters I used to make the sweet potato casserole part. I do not rinse between but shake them off well. topping for sweet potato casserole being mix with beaters
  • Sprinkle the pecan brown-sugar topping evenly on top.
  • I sprinkle a little orange zest on top as well. The day I made this dish I did not have an orange to zest. Luckily, I had some Valencia Orange Peel in a jar (affiliate link). I always keep a little on hand for this situation – just in case.jar of valencia orange peel
  • The original recipe calls for a higher temperature and quicker cooking time. I find this recipe (without eggs) sets up a little bit better with a lower cooking temperature and slower cooking time. Be aware though that the finished product with thicken better upon standing. You don’t really want this dish piping hot anyway, but more luke-warm.sweet potato casserole in white pan

  1. Thanks for sharing this recipe. I used to make a similar version with eggs that I would prep ahead of time (basically, made it but didn’t cook it and refridgerated it until cooking time). Can I do that with this recipe? I am just wary of what happens to cornstarch if it sits mixed with other ingredients in the fridge.

    • Hi, thanks for asking a great question! I honestly think it will be fine. It might start to separate from the liquid a little bit. Here is what I would do to be safe. Go ahead and put the sweet potato mixture in the casserole dish and keep the brown sugar pecan topping in a separate container (no need to refrigerate). Then, just before cooking, give the sweet potato mixture a little stir and THEN sprinkle the prepared pecan brown sugar topping on. Bake as usual. Since it will be cold though going into the oven, you might need a little extra cooking time. Good luck:)

      • Thank you so much for writing me back so quickly. I pre-made the casserole up to the cooking point a day ahead and it turned out perfectly! Honestly, I actually forgot to stir it but it didn’t look separated and it tasted great. Thanks again for sharing this recipe.
