Low FODMAP Carrot & Fennel Soup

FEATURED IN Dinner, Lunch, Vegetarian Options

This delicious carrot & fennel soup is super easy to make, and has a sweet aromatic taste that goes perfectly with crunchy low FODMAP bread.

Note on fennel seeds & sweet potato: Fennel seeds are considered low FODMAP at a 1 teaspoon serves according to Monash Low FODMAP app. Sweet potato can be high FODMAP if you consume more than 1/2 a cup (70g). This recipe contains a low FODMAP serving size of 50g of sweet potato per person –  just make sure you divide the soup into the recommended number of serves. If you are worried about the sweet potato just replace it with parsnip.

  1. Thinly slice the green tips of the leek. Peel and cut the potato, carrot and sweet potato (parsnip) into small pieces. Roughly chop the fresh cilantro. Place the garlic infused oil and olive oil in a large saucepan. Over low heat cook the leek tips for 1 to 2 minutes, stirring occasionally.
  2. Then add the potato, carrot, and sweet potato (parsnip) to the saucepan, and cook over low heat for five minutes, stirring occasionally.
  3. Prepare the vegetable or chicken stock if needed (I dissolved Massel Chicken Stock Cube 7's in boiling water). Add the stock to the saucepan. Turn up the heat to medium-high and bring the soup to a rolling boil. Put the lid on the saucepan and allow the soup to simmer for 10 to 15 minutes, until the vegetables are tender.
  4. Meanwhile melt the dairy free spread (olive oil spread or butter) in a frying pan. Add the fennel seeds and cook for 1 minute, stirring constantly. Add the fresh cilantro and cook for a further minute, then remove from heat. Then add the fresh cilantro and fennel seed mixture to the soup.
  5. Once the vegetables are tender, remove the soup from the heat and leave to cool for 10 minutes. Transfer the soup to a food processor or blender, in batches if needed, and process the soup until smooth. Rinse out the soup pot and then return the soup. Over low heat mix in the low FODMAP milk, and season with a few grinds of salt and pepper to taste.
  6. Serve the soup warm with a sprinkle of fresh cilantro and a side of toasted low FODMAP bread.

    Storage Tip: This soup freezes well. You can either reheat on a stovetop or in a microwave until warm.

Buying Tips

Garlic infused oil is found in the oil section of your local supermarket. It should be clear with no floating bits of garlic. You can also make garlic infused oil at home by frying garlic cloves in cooking oil, until they are golden and fragrant (then remove the garlic before you continue cooking your meal). This is a low FODMAP way to capture the garlic flavour as the fructans can't leach into the oil.

Make sure you buy a leek that has long green tips (this is the low FODMAP part), as you can’t use the white/light green leek bulb (this part is high FODMAP).

Sweet potato is low FODMAP in 70g serves and becomes high FODMAP in larger serves. Our recipes only use a low FODMAP portion of sweet potato. However if you are concerned you can normally swap the sweet potato for regular potato, carrot or parsnip.

Choose a stock that does not include onion or garlic. We prefer to use Massel Chicken Stock Cube 7's (in the yellow & blue packet). This product is low FODMAP, gluten free and vegan (despite it's name) and each packet makes 7 cups of stock. This product can be brought online around the world and is available from some supermarkets.

Wheat or spelt sourdough breads make good options. Also check your Monash or FODMAP Friendly apps for certified low FODMAP breads in your area. Avoid ingredients like inulin, apple or pear juice, apple fibre, concentrated fruit juices, honey, or high fructose corn syrup. Also check what flours have been used, avoid products that contain amaranth flour, lupin flour, chickpea/besan/gram/garbanzo bean flour, lentil flour or large amounts of soy flour or coconut flour especially if choosing gluten free bread.

Gluten Free Tips

Herbs and spices are naturally gluten free, however they can become contaminated during manufacturing processes. If you are highly sensitive to gluten, check the dried herbs and spices do not contain a warning for trace gluten. If you are just on the low FODMAP diet you do not need to worry about this.

Dairy Free Tips

Use a dairy free spread or olive oil spread instead of butter. Butter is considered low FODMAP.
