Cooking oil changes both the flavour of an Indian dish and how it behaves at different cooking temperatures. I do not use one oil for everything: I choose according to the dish, the cooking method and how strongly I want the oil itself to taste.
This guide compares cold-pressed and refined oils, basic fat terminology, smoke point and the oils I use most often in Indian cooking. In my kitchen, mustard oil, rice bran oil, peanut oil, sesame oil and ghee all have different jobs, from tadka and everyday curries to pickles, air-fryer recipes and deep frying.

Understanding cooking oils: a few basics
Cold-pressed vs refined oil
Cold-pressed and unrefined oils usually retain more of their characteristic aroma and flavour, while refined oils are generally more neutral. Refining can also change how an oil behaves at higher cooking temperatures, so I look at both the type of oil and whether it is refined or cold-pressed before deciding how to use it.
I do not treat cold-pressed as automatically better for every cooking method. For example, I use cold-pressed peanut oil for deep frying, but I keep the heat more moderate because the cold-pressed version starts smoking sooner than a refined version. Exact smoke points vary with the oil, processing and product.
Saturated, monounsaturated and polyunsaturated fats
Cooking fats contain different proportions of saturated fat (SFA), monounsaturated fat (MUFA) and polyunsaturated fat (PUFA). Ghee and coconut oil contain more saturated fat, while oils such as mustard, peanut, olive, avocado, sesame and rice bran contain different combinations of unsaturated fats. I use this as background information rather than judging an oil from one percentage alone.
SFA: saturated fatty acids are one part of the fat composition of an oil or cooking fat. MUFA: monounsaturated fatty acids are present in varying amounts in oils such as olive, peanut, mustard, avocado and rice bran. PUFA: polyunsaturated fatty acids include omega-3 and omega-6 fats, and the proportions vary by oil.
Omega-3 and Omega-6
Omega-3 and Omega-6 are types of polyunsaturated fats. Different cooking oils contain them in different proportions, but this information alone does not tell you whether an oil is the best choice for tadka, frying or a particular Indian dish. For this guide, flavour, refinement and cooking temperature are more useful practical factors.
What about trans fat?
Trans-fat content should be checked on the nutrition label of the specific packaged oil. A comparison between two individual products does not mean that every refined oil contains trans fat or that every cold-pressed oil has the same nutrition profile. Product formulation and processing vary, so I prefer to use the label rather than make a blanket assumption.
Smoke point and cooking temperature
Smoke point is the temperature at which an oil begins to produce visible smoke. It is useful when choosing an oil for sautéing, frying or air frying, but I do not treat one published number as a universal rule because smoke point can vary with refinement, processing, age and the specific product.
The refined and cold-pressed versions of the same oil can behave differently at higher temperatures. In practice, I use the label and the way the oil behaves in the pan rather than assuming that a smoke-point figure for a refined oil also applies to its cold-pressed version.
This matters especially with peanut oil. I do use peanut oil for deep frying, but when I am using a cold-pressed version I keep the heat more moderate and avoid pushing it to the point where it smokes.
How I use smoke point in everyday cooking
For higher-temperature cooking, I prefer an oil that suits the temperature I am actually using and the flavour I want in the finished dish. For air-fryer recipes, that often means a fairly neutral oil such as avocado, rice bran or peanut oil. For deep frying, I commonly use peanut or rice bran oil, while keeping the temperature more moderate when the oil is cold-pressed.
If an oil begins to smoke during cooking, I reduce the heat rather than continuing at that temperature. This simple approach is more useful in my kitchen than relying on one fixed smoke-point table for every refined and unrefined oil.
Choosing the right oil for Indian cooking
There is no single oil that I use for every Indian dish. I choose according to flavour, cooking temperature and the role the oil plays in the recipe. Stronger oils such as mustard or sesame can become part of the flavour of the dish, while rice bran, avocado and some peanut oils are useful when I want a more neutral result.
| Cooking use | What I usually choose | Why |
|---|---|---|
| Tadka / tempering | Mustard oil, rice bran oil, peanut oil or ghee | I choose according to the flavour of the dish. |
| Sindhi cooking | Sesame oil when the dish is not deep-fried | I like its flavour in many traditional dishes. |
| Pickles | Sesame oil or mustard oil | When I use mustard oil for pickle recipes, I heat it first and let it cool before adding it. |
| Air fryer | Avocado, rice bran or peanut oil | These are useful when I want a fairly neutral oil that suits the temperature I am using. |
| Deep frying | Peanut or rice bran oil | With cold-pressed peanut oil, I keep the heat more moderate rather than treating it like refined peanut oil. |
Mustard oil
Mustard oil has a strong, pungent flavour that is noticeable in the finished dish. Cold-pressed mustard oil tastes and smells even stronger, so I use it when that flavour suits the recipe rather than as a completely neutral cooking oil.
I commonly use mustard oil for tadka and for pickles. For my pickle recipes, I heat the mustard oil first and then let it cool before mixing it with the other ingredients. Check the label of the product you buy for its intended culinary use and storage instructions.
Sesame oil
Sesame oil, also called gingelly oil in some regions, has a distinct nutty flavour. It is one of my preferred oils for Sindhi cooking when the dish is not being deep-fried, and I also use it in some pickle recipes.
For everyday cooking I use it for sautéing, stir-frying and other moderate-temperature methods. The flavour varies by product, so a mild cooking-grade sesame oil will taste different from a strongly toasted sesame oil used mainly for finishing.
Groundnut / peanut oil
Peanut oil can be fairly neutral or more nutty depending on how it is processed. I use it for everyday cooking, tadka and deep frying. It is also one of the oils I use when I want the spices and other ingredients to remain the main flavour.
When I use cold-pressed peanut oil for deep frying, I keep the heat more moderate because cold-pressed oil generally starts smoking sooner than a refined version of the same oil. I do not use a refined-oil smoke-point figure as a target for a cold-pressed product.
Rice bran oil
Rice bran oil has a mild flavour, which makes it useful when I do not want the oil to compete with the spices. I use it for tadka, frying and air-fryer recipes, especially when I want a neutral-tasting option.
Commercial rice bran oils can differ in how they are processed, so I check the product label rather than assuming every brand is the same. For this guide, its main advantage is practical: the flavour is mild and it works across several Indian cooking methods.
Ghee
Ghee is not an oil, but it has an important place in Indian cooking. I use ghee instead of oil when I specifically want its richer aroma and flavour, particularly for tadka, some traditional dishes and Indian sweets.
Because ghee changes the flavour of a dish quite noticeably, I do not treat it as a neutral substitute for oil. It is also dairy-based, so it is not suitable when I want the recipe to remain vegan.
Coconut oil
Coconut oil is extracted from coconut and unrefined versions have a distinct coconut aroma. I use it when that flavour fits the dish rather than as an all-purpose neutral oil.
It works particularly well in recipes where coconut is already part of the flavour profile. Refined and unrefined coconut oils can behave differently in cooking, so check the product label and choose according to the temperature and flavour you need.
Avocado oil
Avocado oil is one of the neutral-tasting options I consider for air-fryer recipes, especially when I want the seasoning rather than the oil to dominate the flavour. I also use the product's stated temperature guidance when choosing it for higher-temperature cooking.
The main drawback for everyday Indian cooking is usually price; it can cost considerably more than rice bran or peanut oil.
Olive oil
Olive oil has its own flavour, especially extra-virgin olive oil, so I choose it according to the dish rather than assuming it will suit every Indian recipe. It can work for sautéing, roasting, salads and dishes where its flavour is welcome.
For very high-temperature cooking, check whether the particular olive oil is refined or extra virgin and follow the product guidance instead of treating all olive oils as identical.
Sunflower oil
Sunflower oil is a mild-flavoured option for everyday cooking. Its fatty-acid profile and heat tolerance vary by type, including high-oleic versions, so check the product label and choose it according to the cooking method you plan to use.
Canola oil
Canola oil is another neutral-flavoured oil that can be useful when I do not want the cooking fat to add a strong taste. As with other oils, I choose the specific product according to the dish, refinement and cooking temperature rather than from one nutrition number alone.
Conclusion
For Indian cooking, I find it more useful to keep a few oils for different jobs than to search for one oil that is best for everything. Flavour, refinement and cooking temperature all matter.
For tadka I may use mustard, rice bran, peanut oil or ghee. For many Sindhi dishes that are not deep-fried, I like sesame oil. For pickles I commonly use sesame or mustard oil, and I heat and cool mustard oil before adding it to the pickle. For air-fryer recipes I usually want a fairly neutral oil such as avocado, rice bran or peanut oil.
The strongest practical difference is often flavour. Cold-pressed mustard oil is noticeably pungent, ghee adds a rich buttery aroma, sesame oil has a nutty character, while rice bran and some peanut or avocado oils stay more in the background. Choosing the oil to match the recipe gives a more predictable result than judging it from a single nutrition claim or smoke-point number.
