2020 Update: Cherry tomatoes have been retested by Monash University and found to be high FODMAP due to the fructose content. However, if you limit the cherry tomatoes to 3 in your own portion this would be classed as low FODMAP. Just serve some extra veg with it such as green beans or salad.
This is a really simple but very tasty low FODMAP meal. Just pre-boil the potatoes, place them in a baking tray with the other ingredients then cook in the oven for 15 minutes and it’s ready. It’s also easy to do if you have guests coming round and it shouldn’t take any longer to do for more people – you just need more oven trays! I often cook for our weekly family gatherings so I’m always looking for simple ideas to feed a crowd and this works so well. If you use a thicker white fish such as cod you may need to increase the cooking time by 5-10 minutes.
If you need more inspiration check out my other low FODMAP fish recipes.
- 750g baby new potatoes (cut any larger potatoes into halves)
- 250g cherry tomatoes, on the vine - however please see the note above and limit your portion of cherry tomatoes to just 3 to keep it low FODMAP
- 70g pitted black olives
- 4 skinless haddock fillets (or any similar white fish)
- 2 tablespoons garlic flavoured olive oil
- Juice of 1 lemon
- A pinch of salt and pepper
- A large handful of fresh basil leaves roughly chopped or torn
- Preheat the oven to 200 degrees C (400 F/ gas6)
- Boil the new potatoes for 15 minutes until just cooked and drain
- Place the potatoes in a large baking tray (or use 2 smaller ones) followed by the olives and tomatoes and lay the haddock fillets on top
- Drizzle the garlic flavoured olive oil over the fish and potatoes and squeeze over the lemon juice
- Add a pinch of salt and pepper, cover the tray loosely with tin foil and transfer to the oven to cook for 15 minutes. Ensure fish is cooked through
- Once cooked, sprinkle over the basil leaves then serve
This was one of the best dishes I’ve had in a long time and it was one of the easiest to prepare add as well.
Thanks for the feedback Karen, really glad you enjoyed it!
I’m confused. I thought we weren’t allowed garlic
Hi Jane, garlic flavour olive oil has been tested for FODMAPS and is fine as it doesn’t contain any fructans.
Great dish. Finding out about using garlic infused olive oil has been fantastic for me.
I cant believe hiw healthy i feel on low fodmap!
Hi Robert, glad you enjoyed it! Garlic oil is a great substitute for garlic, well worth getting some if you’re trying the diet. Best wishes, Louisa
Thanks Louise. I have suffered with IBS since the age of 16 and I am now 36 and I just cannot believe the difference. GPs could do nothing for me.
I do get an occasional flare up, but nothing to the daily run to the toilet I used to get. Your recipes are amazing.
Thanks again, more people with IBS should try this path!
Thanks Robert ?
I am sure I saw that cherry tomatoes were not a low fodmap food. Can you please confirm
Hi Mike, cherry tomatoes are only a problem if eaten in large quantities so if you have a look at the Monash FODMAP app it states that 220g contain moderate amounts of fructans. This recipe is for 4 so is well within limits! Best wishes, Louisa
