Most individual spices in curry powder are low FODMAP, but commercial curry powder blends are often not safe because they frequently contain garlic powder, onion powder, or both. These two ingredients are among the highest FODMAP foods, and even small amounts can trigger symptoms in sensitive people. The good news is that making your own blend or carefully reading labels can solve the problem entirely.
Why the Spices Are Fine but the Blend Isn’t
The core spices in curry powder, including turmeric, coriander, cumin, ginger, black pepper, cinnamon, cardamom, and fenugreek, are all low FODMAP at typical serving sizes. The USDA lists these as the standard ingredients for curry powder, and none of them contain the short-chain carbohydrates that cause trouble on a low FODMAP diet.
The problem is what manufacturers add beyond those base spices. Garlic powder and onion powder are cheap, potent flavor boosters, and they show up in a huge number of commercial spice blends. They aren’t always listed prominently on the label, and they sometimes hide under terms like “spices” or “natural flavors.” Both are concentrated sources of fructans, one of the main FODMAP groups, and even a quarter teaspoon can push a serving into high FODMAP territory. If a curry powder lists either ingredient, it’s not safe for the elimination phase.
How to Find a Safe Curry Powder
Your first option is to check the ingredient list on any curry powder you already own. If it lists only spices like turmeric, coriander, cumin, ginger, pepper, cinnamon, fenugreek, and cardamom with no garlic or onion in any form, it’s likely low FODMAP at a standard serving of one to two teaspoons. Some brands do sell garlic-free and onion-free blends, though they don’t always advertise this on the front of the package.
A few specialty brands now market curry powders specifically designed for low FODMAP diets. These are worth seeking out if you want to skip the label-reading step, though they tend to cost more than standard supermarket options. Look for products that carry Monash University or FODMAP Friendly certification, which means they’ve been lab-tested for FODMAP content at specific serving sizes.
Making Your Own Blend
The most reliable approach is mixing your own curry powder. It takes about five minutes, stores well in a sealed jar for months, and gives you full control over what goes in. A well-balanced low FODMAP curry powder uses roughly these proportions:
- 4 tablespoons ground coriander
- 4 tablespoons ground cumin
- 3 tablespoons ground turmeric
- 4 teaspoons ground ginger
- 2 teaspoons mustard powder
- 2 teaspoons ground cinnamon
- 1 teaspoon ground cardamom
- 1 teaspoon black pepper
- 1 teaspoon cayenne pepper
- 2 teaspoons ground asafetida (hing)
This makes a large batch. Use one to two teaspoons per serving, the same way you’d use any store-bought curry powder.
Asafetida: The Garlic and Onion Substitute
Asafetida, also called hing, is the ingredient that makes a garlic-free curry powder still taste like curry powder. It’s a resin from a plant root that delivers a savory, pungent flavor remarkably similar to garlic and onion once it hits hot oil. A small pinch (about 1/8 teaspoon) is enough for a dish serving three to four people.
The key to using asafetida well is tempering it in oil first. Heat a small amount of a cooking oil you tolerate, add the hing, and let it sizzle for a few seconds before adding your other ingredients. This step mellows the raw sharpness and brings out the savory depth. Use it in moderation, though. It’s a strong spice, and too much can cause stomach irritation even though its FODMAP load is low. It’s also meant to replace garlic and onion, not accompany them.
One thing to watch: some commercial asafetida products are cut with wheat flour as a bulking agent. If you’re also avoiding gluten, check the label or look for pure asafetida powder.
Chili and Cayenne: Low FODMAP but Not Always Tolerated
Many curry powders contain cayenne pepper or chili powder, both of which are low FODMAP. However, the capsaicin in these spices can independently trigger digestive symptoms in people with IBS, particularly those with the diarrhea-predominant type. Research published in the Journal of Neurogastroenterology and Motility found that a single chili-containing meal produced more abdominal pain and burning in IBS patients compared to healthy volunteers.
Interestingly, that same research found a desensitization effect with regular chili consumption. After several weeks of daily intake, participants experienced reduced abdominal burning and increased tolerance. So if cayenne bothers you initially, you might build tolerance over time with small, consistent amounts. But during the elimination phase, it’s reasonable to start with a milder blend and add heat gradually as you gauge your response.
Other Low FODMAP Curry Flavor Boosters
If you’re building flavor in a curry dish beyond just the powder, several ingredients work well without adding FODMAPs. Fresh ginger (in tolerated amounts), green chilies in moderate quantities, cumin seeds, fresh coriander leaves, and turmeric all contribute layers of flavor. Garlic-infused oil is another popular option: because fructans don’t dissolve in fat, you can infuse oil with whole garlic cloves, discard the cloves, and keep the flavor without the FODMAPs.
Combining these with your homemade curry powder gives you a dish that tastes rich and complex without relying on garlic or onion in any form. The restriction is narrower than it first seems. The vast majority of curry spices are perfectly safe, and the two that aren’t have good substitutes.
