I'm really picky about what goes into my holiday recipes, especially the ones that are iconic, like sweet potato pie and sweet potato casserole with marshmallows.  It's the mallows, ya'll!

Incidentally, if you've never heard a girl from the Midwest speak with a southern drawl, amuse yourself sometime and request it. It's the funniest danged thing ya'll will ever hear.

What I mean to say is that the sweet potato casserole that I eat on Thanksgiving must have marshmallows in it.

Canned Sweet Potato Casserole

What I love the most about this particular recipe is how budget friendly it is. Because I purchased absolutely every ingredient for the recipe at Dollar General, this delicious canned sweet potato casserole cost me less than fifty cents per serving to make. That's crazy awesome, especially since the price of sugar has risen so much in the past year.

There are just a few simple ingredients and a couple of spices needed to make the recipe:

  • canned yams or peeled and cooked sweet potatoes.. (read more below)
  • brown sugar – to lower the calories, you can use a low glycemic brown sugar substitute
  • butter
  • maple syrup
  • chopped pecans
  • mini marshmallows – or use these vegan marshmallows

How do you make sweet potato casserole with canned potatoes?

Assembling the canned sweet potato casserole is super quick and easy. All you need to do is drain the canned sweet potatoes , then mash 'em, mix in the rest of the ingredients, top it off with mini marshmallows and put it into the oven to toast those babies up.

It doesn't get any easier and it definitely meets the It's Yummi test for taste! Now if you want to use fresh sweet potatoes you most certainly can. You want to peel and pre-boil (much like how to make mashed potatoes) them ahead of time then proceed with the recipe.
