Low FODMAP mashed potatoes

Some recipes are so simple that I hesitate to publish them on the blog at all. On the other hand, it is also nice to have a number of basic recipes on the blog.

This recipe for low lactose and low FODMAP mashed potatoes is one of them. Easy, fast and tasty.

The ingredients of the low FODMAP mashed potatoes

This recipe consists of only a handful of ingredients:

  • Starchy potatoes: the best potatoes for mashing. For example Russet Gold potatoes.
  • Lactose-free milk: after mashing, add a little lactose-free milk to the potatoes to make them extra creamy. You can also use plant-based milk.
  • Optional: lactose-free cream: I add a few tablespoons of lactose-free cream to the mashed potatoes to make the mashed potatoes even creamier. You can also omit this.
  • Butter: at the end stir a little bit of butter into the mashed potatoes. Due to the processing process, butter is almost lactose-free.

    This makes it low FODMAP and many people with lactose intolerance can tolerate some butter. If you have to eat strictly lactose-free, you can also omit this or replace it with lactose-free margarine.

Vegan mashed potatoes

You can also easily make this recipe vegan. Then use plant-based milk instead of lactose-free cow’s milk. Omit the whipped cream and substitute the butter for vegetable margarine.
