Who else loves mashed potatoes? We do! So, we had to find the perfect low FODMAP mashed potatoes recipe.

Are potatoes low FODMAP?

White potatoes are considered low FODMAP friendly food but can be prepared using high FODMAP ingredients (think garlic, onion, milk) which can trigger uncomfortable symptoms.

Our recipe is delicious and contains no high FODMAP foods, and did we mention it is easy to make? We made our potatoes in the slow cooker so you can set it and forget it, freeing up your time to focus on other low FODMAP thanksgiving favorites.
