15 Low FODMAP Instant Pot Recipes for IBS (Garlic & Onion Free)

Pressure cooking and the low FODMAP diet suit each other far better than most people expect. The two habits that usually derail a low FODMAP week are time and flavour: dinner takes too long, and food tastes flat once garlic and onion are gone. An electric pressure cooker fixes both. It turns tough cuts tender in 20 minutes, it extracts flavour from herbs, spices, citrus and garlic-infused oil under pressure, and it lets you batch-cook rice, potatoes and protein in the same pot.

Every recipe below is garlic-free and onion-free, uses low-FODMAP portions, and lists real pressure times so you are not guessing. Timings assume a standard 6-quart electric pressure cooker; if you use a stovetop model, reduce times by about 15 percent.

Key Takeaways

• Garlic-infused oil is the flavour engine. FODMAPs in garlic and onion are water-soluble, not fat-soluble, so infused oil carries the taste without the fructans. Never add whole garlic cloves to the pot - the cooking liquid pulls the fructans straight out.
• Use the green tops of spring onions and leeks only. The white bulbs are high in fructans; the green parts are low FODMAP and give you that savoury base note.
• Watch stock, not just vegetables. Most supermarket stock cubes contain onion and garlic powder. Use a certified low FODMAP stock, or water with herbs, salt and a little infused oil.
• Portion at plating time. Stacking is the most common hidden trigger - three "safe" half-serves in one bowl can add up to a high FODMAP meal.
• Natural release matters for meat, quick release for vegetables. Meat stays juicy with 10 minutes of natural release; vegetables turn to mush if you let them sit under residual pressure.

1. Lemon Herb Chicken and Rice Bowls

The workhorse of low FODMAP pressure cooking. Sauté 800 g diced chicken thigh in 2 tbsp garlic-infused oil, then add 300 g rinsed jasmine rice, 375 ml water, the zest of one lemon, 1 tsp dried oregano and salt. Layer carrot batons on top.

Pressure: 6 minutes high, 10 minutes natural release.
Portions: carrot 75 g per serve; rice contains no FODMAPs, so serve freely.
Storage: 4 days in the fridge, 3 months frozen. Reheat covered with a splash of water.
Tip: stir chopped parsley and a squeeze of lemon through at the end - acid brightens food that has no onion in it.

2. Roasted Carrot and Ginger Soup

Sauté 2 tbsp fresh grated ginger and the green tops of two spring onions in infused oil, add 600 g carrot chunks, 200 g peeled potato and 800 ml low FODMAP stock.

Pressure: 8 minutes high, quick release. Blend smooth and finish with 2 tbsp lactose-free cream.
Portions: carrot 75 g and potato unlimited, so a 300 ml bowl sits comfortably in the green zone.
Storage: 4 days fridge, 3 months frozen in portions.
Tip: a pinch of ground cumin and a squeeze of orange juice make it taste slow-roasted in ten minutes.

3. Beef and Potato Stew

Brown 700 g diced chuck steak in batches - browning is where the depth comes from when there is no onion. Deglaze with 100 ml red wine, add 500 ml low FODMAP stock, 2 tbsp tomato paste, thyme, a bay leaf, 400 g potato and 300 g carrot.

Pressure: 30 minutes high, 12 minutes natural release. Thicken with 1 tbsp cornflour slurry on sauté mode.
Portions: carrot 75 g per serve; keep tomato paste to 2 tbsp across four serves.
Storage: 4 days fridge, 3 months frozen.
Tip: add the vegetables after pressure cooking the beef for 20 minutes if you want them to hold shape.

4. Perfect Fluffy Jasmine Rice

Rice is one of the few genuinely FODMAP-free staples, which makes it the safest base on the diet. Rinse 400 g jasmine rice until the water runs clear, add 500 ml water and a pinch of salt.

Pressure: 4 minutes high, 10 minutes natural release, then fluff.
Portions: no limit - white rice contains no measurable FODMAPs.
Storage: cool within one hour, refrigerate up to 3 days, reheat once until steaming hot.
Tip: cook a double batch and freeze in flat bags; it reheats in three minutes and saves you from takeaway.

5. Lemon Quinoa Salad

Pressure cook 200 g rinsed quinoa with 250 ml water for 1 minute high, 10 minutes natural release. Cool, then fold through diced cucumber, halved cherry tomatoes, chopped parsley and mint, 40 g feta, lemon juice and olive oil.

Portions: quinoa 155 g cooked, cherry tomatoes 75 g, cucumber 75 g, feta 40 g per serve.
Storage: 3 days fridge; dress just before eating so it stays crisp.
Tip: quinoa is a complete protein and higher in fibre than rice, which helps if constipation is your dominant IBS pattern.

6. Shredded Chicken for Tacos

Place 800 g chicken breast in the pot with 150 ml water, 1 tbsp garlic-infused oil, 2 tsp smoked paprika, 1 tsp cumin, 1 tsp dried oregano and salt.

Pressure: 10 minutes high, 5 minutes natural release, then shred in the pot so it soaks the juices back up.
Portions: serve in corn tortillas (naturally gluten free) with lettuce, tomato 75 g and lime.
Storage: 4 days fridge, 3 months frozen.
Tip: check your taco seasoning packet - almost all contain onion and garlic powder. Mix your own from the spices above.

7. Fresh Marinara Sauce

Jarred pasta sauce is one of the biggest hidden FODMAP sources in a supermarket trolley. Make your own: 2 x 400 g tins chopped tomatoes, 3 tbsp garlic-infused oil, 1 tsp sugar, basil stalks, salt.

Pressure: 8 minutes high, quick release, then reduce on sauté for 5 minutes and stir in torn basil.
Portions: 100 g sauce per serve keeps tomato within tolerance; canned tomatoes are low FODMAP at 92 g.
Storage: 5 days fridge, 3 months frozen. See the full low FODMAP pasta recipe collection for ways to use it.
Tip: a parmesan rind dropped in during pressure cooking adds the savoury weight onion would have given.

8. Foolproof Hard Boiled Eggs

Eggs are FODMAP-free and one of the easiest protein snacks on this diet. Put 250 ml water in the pot, add a trivet and up to 12 eggs.

Pressure: 5 minutes high, 5 minutes natural release, 5 minutes in ice water - the shells slip straight off.
Portions: no limit; two eggs make a genuinely filling snack.
Storage: 7 days in the fridge, unpeeled.
Tip: mash with lactose-free yoghurt, chives and a little Dijon for a safe egg salad. More ideas in our low FODMAP snack ideas list.

9. Creamy Mashed Potatoes

Pressure cook 1 kg peeled, quartered potatoes with 250 ml water for 8 minutes high, quick release. Drain, then mash with 50 g butter and 100 ml warm lactose-free milk.

Portions: potato has no FODMAP limit; the dairy is the variable, so lactose-free is essential here.
Storage: 3 days fridge; loosen with extra milk when reheating.
Tip: infuse the milk with a bruised sprig of rosemary and the green top of a leek while the potatoes cook.

10. Chicken and Rice Congee

The single most soothing thing you can make during a flare. Combine 150 g rice, 1.5 litres water, 400 g chicken thigh, sliced ginger and salt.

Pressure: 25 minutes high, full natural release. Shred the chicken and stir back through.
Portions: unlimited - rice, chicken and ginger are all FODMAP-free.
Storage: 3 days fridge; it thickens, so add water on reheating.
Tip: top with spring onion greens, a drizzle of sesame oil and white pepper. Low residue and low fat, which helps when your gut is irritable.

11. Steamed Salmon with Lemon and Dill

Add 250 ml water and a trivet, place two salmon fillets on baking paper, top with lemon slices and dill, and lay green beans alongside.

Pressure: 3 minutes high, quick release. Do not walk away - salmon overcooks fast.
Portions: green beans 75 g per serve; salmon has no limit.
Storage: 2 days fridge, best eaten fresh; flake leftovers into the quinoa salad above.
Tip: oily fish supplies omega-3 fats, and a lower-fat cooking method like steaming is often gentler if fat triggers your symptoms.

12. Whole Pot Roast Chicken

Rub a 1.5 kg chicken with garlic-infused oil, salt, pepper and thyme. Brown breast-side down on sauté, then add 250 ml stock, a halved lemon and the green tops of a leek.

Pressure: 24 minutes high, 12 minutes natural release. Crisp the skin under the grill for 5 minutes if you like.
Portions: unlimited chicken; keep gravy to 60 ml if it is stock-based.
Storage: 4 days fridge. Strip the carcass for the congee and tacos above.
Tip: one chicken realistically covers three dinners - this is the cheapest way to keep safe protein in the fridge.

13. Coconut Chicken Curry

Bloom 1 tbsp curry powder, 1 tsp turmeric and grated ginger in infused oil, add 700 g diced chicken, 250 g diced carrot and 200 ml coconut milk.

Pressure: 8 minutes high, 5 minutes natural release, then finish with lime and coriander.
Portions: coconut milk 60 ml per serve (it contains sorbitol above that), carrot 75 g.
Storage: 4 days fridge, 2 months frozen.
Tip: check the curry powder label for onion or garlic powder; single spices are always safer than blends. Our low FODMAP Indian food guide covers spice swaps in more detail.

14. Creamy Parmesan Polenta

Whisk 200 g polenta into 900 ml water with salt, seal and pressure cook 9 minutes high, 10 minutes natural release. Whisk hard, then beat in 30 g parmesan and 20 g butter.

Portions: polenta has no FODMAP limit; parmesan is low FODMAP at 40 g.
Storage: 3 days fridge; it sets firm, so slice and pan-fry the leftovers.
Tip: serve under the beef stew or marinara - a hands-off alternative to 40 minutes of stovetop stirring.

15. Strawberry Rice Pudding

Combine 150 g pudding rice, 600 ml lactose-free milk, 2 tbsp maple syrup, a strip of lemon peel and a pinch of cinnamon.

Pressure: 12 minutes high, full natural release, then stir - it thickens as it cools.
Portions: strawberries 140 g, maple syrup 2 tbsp per serve.
Storage: 3 days fridge, served warm or cold.
Tip: more sweet options are in our low FODMAP dessert ideas round-up.

How to Keep Pressure Cooking Low FODMAP

Build flavour in three layers. Fat first (garlic-infused oil), aromatics second (ginger, spring onion greens, leek greens, herbs, spices), acid last (lemon, lime, a splash of vinegar). That sequence replaces most of what onion and garlic were doing.

Fix your stock. This is where most people accidentally reintroduce fructans. Read the label; if it lists onion or garlic in any form, replace it. Water plus herbs, a parmesan rind and salt works better than you would think.

Do not stack portions. A bowl with 75 g carrot, 75 g cherry tomato and 60 ml coconut milk is fine. Double all three in one meal and you have built a moderate FODMAP load out of low FODMAP ingredients. Use our FODMAP portion checker when you are unsure.

Cook once, portion immediately. Divide into containers while it is hot rather than serving from the pot. It removes the guesswork later in the week.

Reintroduce deliberately. These recipes are for the elimination and maintenance phases. When you are ready to test triggers, change one variable at a time and keep notes.

Frequently Asked Questions

Does pressure cooking reduce FODMAPs?
Not meaningfully. FODMAPs are heat-stable, so cooking does not destroy them. What pressure cooking does do is leach water-soluble fructans into the cooking liquid - which is exactly why you should never add garlic cloves or onion to the pot and then eat the sauce.

Can I use a slow cooker instead?
Yes, and the flavour-building rules are identical. Our low FODMAP slow cooker recipes cover timings for the same kinds of meals.

Is garlic-infused oil really safe?
Yes, provided the garlic is strained out. The fructans that trigger symptoms are water-soluble and do not transfer into oil. Never use oil with garlic pieces left floating in it.

What about onion powder in spice blends?
Onion powder is concentrated fructan and one of the most common accidental triggers. Buy single spices and blend your own.

How do I make it taste less bland?
Salt properly, brown your meat, use plenty of fresh herbs, and finish every dish with acid. Blandness on this diet is almost always an under-seasoning problem rather than a missing-onion problem.

Are these recipes suitable during a flare?
The congee, mashed potato, plain rice and steamed salmon are the gentlest. Save the beef stew and curry for calmer days, since higher fat meals can speed up gut transit for some people.
