If you saw last week, you already know I shared my savory sweet potato casserole, filled with bacon, caramelized onions, mushrooms, roasted garlic, and pecans. It was hearty, savory, delicious. But I think we all need a little sweetness in our lives, too – Don’t you think?

These sweet potato casserole bites are the perfect bit of sweetness and make for a great appetizer for any holiday party. This way, if you’re serving my savory sweet potato casserole, but don’t want your guests to miss out on the marshmallows… well here you go!

When you’re looking for an appetizer, many times a crostini or canapé comes to mind. What do both of those have in common? BREAD! So what do you do if you can’t eat gluten like myself? You substitute in sweet potato, of course!!

Sweet potatoes are a great substitution for bread in these little appetizers. Sweet potato is so versatile and goes with so many different flavors, both savory and sweet! Plus, sweet potato is just so festive this time of year. With just a few more ingredients we have ourselves some tasty sweet potato casserole bites!

Sweet potato rounds are roasted with oil and cinnamon and then topped with a brown sugar pecan crumble and marshmallows and baked until toasted.

What Size Sweet Potato is Best?

So normally I’m not very choosy about my produce. In fact, I sometimes pick out the uglier produce at the store because I feel like no one else will buy it and I know I can use it because aesthetics aren’t everything.

But, this isn’t one of those times. You have to be a little choosy with your sweet potatoes, here.

You want to pick a sweet potato that isn’t too wide, because we’re slicing it into rounds. So try to pick a sweet potato that has an even thickness, about 2 inches wide. Leave the larger sweet potatoes for baked potatoes!

You want to make sure it’s as even as possible because you don’t want some of your sweet potato rounds to cook faster than the others. So just keep that in mind when shopping for your sweet potatoes!

How Are These Gluten-Free?

We’re using a gluten-free flour blend in our brown sugar pecan crumble to get a cookie-like topping for our sweet potato casserole bites. Other than that, the whole recipe is naturally gluten-free.

Use your favorite gluten-free flour blend here. It doesn’t matter too much what you use because it’s acting as a binder for our brown sugar pecan crumble. Some of my go-to’s include Bob’s Red Mill 1-to-1 Baking Flour, Namaste gluten-free flour blend, GF Jules and Pamela’s

You can typically find one of these blends at your local grocery store in the baking aisle.

Tips for Making Sweet Potato Casserole Bites

Other Dietary Needs

If you’re allergic to nuts, you can leave them out! You can add gluten-free certified oats (preferably purity protocol certified) in the pecans place, or leave the recipe as is without the pecans for more of a cookie-like crumble.
To make this whole recipe dairy-free, substitute non-dairy butter (such as Earth Balance) for the butter called in this recipe.
To make this whole recipe vegan, substitute non-dairy butter as stated above and replace the regular marshmallows with vegan marshmallows. Dandies is a great vegan marshmallow brand and I’ve even heard Trader Joe’s has vegan marshmallows, too!

Watch That Oven!

The cook time as written is for sweet potatoes that are cut to 1/4 inch thick. If you slice these thinner, then your cook time will obviously shorten. So always keep an eye on the oven to see where your sweet potato rounds are at!
When you’re broiling the marshmallows, but sure to watch the oven so they don’t burn. It really only takes 1-2 minutes for them to toast under the broiler so don’t step away!
