Indian food allergens are rarely where people look for them. Nuts hide in creamy sauces as a thickener, dairy hides in marinades and breads, and wheat hides in snacks and in one spice. Knowing the four mechanisms is worth more than memorizing a list of dishes.
Five Indian food allergens come up again and again, and they cluster in predictable places once you know what to look for.
Eggs and soy appear occasionally rather than systematically, usually in breads and in modern fusion items rather than in traditional dishes.
Often, and usually invisibly. This is the single most important thing to understand about Indian food and allergies.
Cashews and almonds are ground into a paste and used to thicken and enrich a sauce. The nuts dissolve completely. There is nothing to see, nothing to pick out, and nothing in the dish name to warn you. A creamy pale curry is the classic case.
The dishes where this is most likely: anything described as korma, anything described as makhani or butter, shahi anything, and most mild pale sauces. Richness and paleness together are the signal.
It depends on the kitchen, and that is not a dodge. Some recipes thicken with cashew paste, some with cream alone, some with both.
At Curry Up Now the allergen guide answers this directly. The makhni butter chicken and makhni butter paneer are listed as containing nuts as well as dairy, while the tikka masala items are listed with dairy and no nuts. That distinction is exactly why asking about the specific dish matters more than asking about the cuisine.
Parts of it are entirely, and parts of it are dairy in places you would never check.
The obvious dairy is cream and paneer. The less obvious is ghee, which is clarified butter and is used as a cooking fat in dishes that otherwise contain no dairy at all. A lentil dish tempered in ghee is not dairy free, and nothing about it looks like it is.
The third one catches almost everybody: yogurt marinades. Tandoori and tikka items are marinated in yogurt before they are grilled. Grilled chicken with no sauce is still a dairy dish.
Southern and coastal cooking, broadly. Rice dishes, coconut based curries, most chickpea and lentil dishes in their plain form, and vegetable dishes cooked in oil rather than ghee.
At Curry Up Now, rice and chana are both listed vegan with no major allergens, and aloo gobi is listed with no major allergens. Those three are the reliable base. Worth knowing on the other side: the allergen guide lists naan as containing dairy and wheat, and the daal as containing dairy and wheat too, which surprises people who assumed the bread and the lentils were safe.
Our guides to vegan and vegetarian Indian food and chana masala cover how to build a plate on that basis, and paneer explains the one ingredient there is no way around.
Predictable with one exception. Rice dishes, most curries and most legume dishes contain no wheat. The breads and the fried snacks do, because both are built on flour.
The exception is asafoetida, usually sold as hing. It is a resin blended with a carrier flour so it can be handled, and that carrier is normally wheat. It is used in tiny amounts, which is exactly why it gets left off ingredient lists, and it appears across lentil and vegetable cooking.
Our guide to gluten free Indian food walks through which dishes clear, and Indian flatbreads covers the breads specifically.
Four that rarely make it into the conversation.
Three structural reasons, none of which is anyone being careless.
The upside is that once you know the mechanisms, they are consistent across restaurants. Ground nuts always thicken, ghee is always dairy, yogurt always marinates. The pattern transfers even when the menu does not.
No, and it often means the opposite. Vegetarian Indian cooking leans harder on dairy and nuts than meat cooking does, because that is where the richness and protein come from when meat is off the table.
Paneer, cream, yogurt and ground cashew do a lot of work in vegetarian dishes. Vegan is the useful label if dairy is the issue, not vegetarian. Our guide to vegetarian Indian ordering covers the difference.
Ask about mechanisms, not dishes. That single change makes the conversation far more reliable.
If a restaurant publishes an allergen guide, start there. It answers most of this before anyone has to speak, and it also tells you how seriously the kitchen takes the question.
An honest no, sometimes, and that is a good sign rather than a bad one. A kitchen that cannot guarantee separation and says so is more trustworthy than one that agrees to everything.
Shared equipment is the limiting factor in almost every restaurant. A dish can contain no allergen and still be unsafe for someone with a severe allergy if it came out of a shared fryer or off a shared tandoor. No ingredient list captures that, which is why it has to be asked separately.
By letting you filter rather than read. The allergen guide lets you pick what you cannot eat and hides every dish that contains it, which turns a long conversation into a short check.
What it covers and what it says:
The honest summary: the guide gets you to a shortlist in under a minute, and the conversation at the counter covers the equipment question that no guide can answer. Both steps matter.
Say it when you book, not on the day. On the catering side, halal, vegan, vegetarian, gluten free and keto options are built into the standard menu rather than handled as special requests, with the same cross contact caveat. Flagging an allergy at booking means the spread arrives workable rather than needing to be picked through.
Often, and usually as a ground paste rather than visible pieces. Cashews and almonds are used to thicken and enrich creamy sauces, so a dish can be full of nuts with nothing to see. Korma, makhani and shahi style dishes are the most likely.
It depends on the kitchen. Some recipes thicken with cashew paste, some use cream alone. Ask about the specific dish rather than the dish type, because two restaurants can make the same named dish very differently.
Some of it is, but dairy appears in more places than people expect. Cream and paneer are obvious. Ghee as a cooking fat and yogurt as a marinade are not, and both turn up in dishes that look entirely dairy free.
Most commonly dairy and tree nuts, since cream and ground cashew or almond are standard thickeners in rich curries. Wheat is less common in the sauce itself but can arrive through asafoetida.
Ask whether the sauce is thickened with nuts rather than whether it contains nuts, avoid korma and makhani style dishes unless confirmed, check desserts separately, and ask about shared equipment. Tomato based and legume based dishes are usually the safer starting point.
Yes. Ghee is clarified butter. The milk solids are removed, which lowers the lactose considerably, but it remains a dairy product and is not suitable for a dairy free or vegan diet.
Botanically no, it is a drupe. The United States FDA classes it as a tree nut for labeling purposes, so it appears on allergen lists. Many people with tree nut allergies tolerate it, but that is a question for a doctor rather than a menu.
Usually not the first thing to reach for. Naan commonly contains both dairy and wheat, some versions contain eggs, and sesame appears on finished breads. Rice is the safer starch in most cases.
It can be. Commercial asafoetida is blended with a carrier flour that is normally wheat, and it is used in small enough amounts that it rarely appears on an ingredient list. Gluten free versions using rice flour exist.
Indian food allergens are easier to navigate than the cuisine's reputation suggests, as long as you ask about mechanisms rather than dishes. Ground nuts thicken, ghee cooks, yogurt marinates and hing hides wheat. Those four cover most of what goes wrong.
Use a published allergen guide to shortlist, then ask the counter the one question no guide can answer, which is whether the equipment is shared. And treat an honest no from a kitchen as useful information rather than a letdown.
