Oven-roasted carrot, parsnip & sweet potato

Thinking up side dishes is my least favorite part when preparing a 3-course dinner. Especially since we are rather limited in the amounts of vegetables that we can eat on the FODMAP diet, it isn’t easy to come up with a suitable vegetable side dish.

But now I have a delicious and easy recipe for you. A low FODMAP vegetable side dish with oven-roasted carrot, parsnip, and sweet potato from the oven!

Low FODMAP serving sizes

Carrots and parsnips are both vegetables that are low FODMAP in large quantities. That is great for a several-course dinner where you will probably eat different dishes.

At the time of writing, Monash University indicates that carrot remains low FODMAP up to a 500-gram serving.

With parsnip, the app indicates that no FODMAPs have been found in this product and that you can eat it unlimited.

Sweet potato is limited low FODMAP. A portion of 75 grams is low FODMAP. A serving of 100 grams of sweet potato contains an average amount of mannitol.

If you already eat other products that also contain mannitol during your dinner, you have to be careful with this. You can also choose to use regular potatoes instead of sweet potatoes.

Regular potatoes are low FODMAP in larger servings.

An easy low FODMAP vegetable side dish

This is a nice inexpensive side dish: carrot, parsnip, and sweet potato are all fairly inexpensive ingredients. If you replace sweet potato with regular potato, this recipe is even more budget-proof.

Apart from peeling and cutting vegetables and potatoes, this is a very easy dish. You throw everything in the oven, be patient, and your side dish is ready 🙂
