It wasn’t as easy as I thought it would be to make a low FODMAP soup. Many of the ingredients found in recipes or store-bought soups are high in FODMAPs. Including garlic and onions, and broths and stocks. These are all common soup base ingredients. This formed a unique challenge for me as an IBS dietitian. But, with a little research and a lot of experimenting, I found the perfect combination of ingredients to bring you a simple, yet delicious homemade parmesan tomato soup!
What is the best onion substitute?
Fresh fennel was the winner as the substitute for onion! Fennel is a green and white herb that has a distinct liquorice flavour when eaten raw. Sautéed and browned in butter, the flavour is softened and provides a good base for this tomato soup. Alongside the diced tomatoes it also produces a perfect texture for the soup.
Instead of garlic powder, ground coriander and fresh basil are used. So, rest assured, this dish is still full of a pleasant aroma.
Add this soup to your back pocket for a simple soup to make if you don’t want to worry about consuming a store bought product that may include FODMAPs! Looking for another low FODMAP soup option? Try this low FODMAP broccoli cheddar soup which packs a punch of delicious flavour!
How do you pimp up tomato soup?
There are many things you can add into tomato soup to give it that extra boost of flavour or texture. For example, some toasted pumpkin seeds add a great nutty crunchy flavour. A drizzle of garlic infused oil works wonders for the flavour. Another option is to add some fresh chopped green onions ontop.
Are canned tomatoes FODMAP friendly?
Canned tomatoes are FODMAP friendly. They are well tolerated in serving sizes of of 2/3 cup – 1/2 cup per meal. This low FODMAP parmesan tomato soup is a great option for enjoying tomatoes in a FODMAP friendly way.
