Grandma's Special Low-FODMAP Sweet Potato Casserole Recipe 2 ways; Gluten-free, Vegan (1)

The holidays would not be the same without low-FODMAP sweet potato casserole. If I only ate this all night, I would still be satisfied. A little savory and a lot sweet. The best combination. Perfect for a low-FODMAP Thanksgiving.

Since Ishared my low-FODMAP stuffing/dressing recipe, I fine-tuned my grandma’slow-FODMAP sweet potato casserole for Thanksgiving. Plus you can pick between a low-FODMAP pecan top (vegan suitable) and a low-FODMAP marshmallow top for this low-FODMAP sweet potato casserole. Note the addition of parsnips and carrots packs it with more fiber and antioxidants, and you can modify the sugar for your desired level of sweetness.

Which topping is your favorite?

Grandma's Special Low-FODMAP Sweet Potato Casserole Recipe 2 ways; Gluten-free, Vegan (2)

Although this recipe has not been tested, a single serving should be low-FODMAP based on the ingredients.

A FODMAPPERS tip about sweet potatoes:sweet potatoes are not the same as yams. In my home of the United States, the term ‘yam’ is often used interchangeably with ‘sweet potato’. In other parts of the world this is not the case. A ‘yam’ is a brown skinned root vegetable with a white interior; a ‘sweet potato’ is a brown skinned root vegetable with an orange interior (apparently they aren’t even related!). When reviewinglow and high FODMAP lists, a low-FODMAP single portion of sweet potato is 1/2 cup or 70 g, whereas a yam is twice this amount 🙂

Serves 12

Bake 400 F

Prep time: 60 minutes (includes 20 minutes baking)

    Sweet potato casserole

    My company had thirds of this. Absolutely loved it. I served it with the turkey so I did not add sugar to the sweet potato base. The pecans were a wonderful addition . I had to send some home with my guests. All asked for the recipe. 😋

    This sounds delicious! Would it still be low FODMAP if I combined the two toppings into one dish?

      Hi Erin,
      Great question! If you plan to make the recipe 1/2 and 1/2 in the pan, then certainly you could use a half portion of both of the toppings and it would still be low-FODMAP. Hope that is helpful 🙂

    If I cant find parsnips would it be okay to use 2 pounds of carrots? Or should I split the difference between sweet potatoes and carrots?

      Hi there!
      From a FODMAP standpoint, you really should not add more sweet potatoes. The carrots have trace FODMAPs so you can increase those. It may look and taste slightly different but should still be delicious! Thank you

    My daughter suggested I make this for Thanksgiving. It was a huge hit! I am now making it for Christmas dinner, also for New Year’s day dinner. I’m sure it will make an appearance at future family dinners.
