There’s no single oil used across all of Asian cooking. The continent spans dozens of culinary traditions, and the oil of choice depends heavily on the region, the dish, and whether you’re stir-frying at high heat or adding a final drizzle of flavor. That said, a handful of oils dominate: peanut oil, sesame oil, soybean oil, coconut oil, and ghee cover the vast majority of traditional Asian cooking, with rice bran oil and mustard oil playing important regional roles.
Peanut Oil: The Stir-Fry Standard
Peanut oil is one of the most widely used oils in East and Southeast Asian kitchens, especially for stir-frying and deep-frying. Its smoke point sits around 450°F (232°C) for the refined version, which means it can handle the intense heat of a wok without breaking down or turning bitter. That stability comes from its mix of monounsaturated and polyunsaturated fats, plus natural antioxidants like vitamin E that resist oxidation during heating.
The flavor is mildly nutty but not overpowering, so it lets the ingredients shine. Chinese wok cooking has relied on peanut oil for generations because it heats quickly, maintains temperature well, and allows food to cook fast while keeping its texture. If you’re looking for one oil to replicate restaurant-style stir-fry at home, refined peanut oil is the closest match. Unrefined peanut oil has a lower smoke point (around 350°F) and a stronger flavor, so it’s better suited to lower-heat cooking or dressings.
Sesame Oil: Two Oils in One
Sesame oil is everywhere in Asian cooking, but it’s really two different products depending on whether the seeds are toasted. Regular sesame oil, made from raw seeds, has a light golden color and a fairly neutral taste. Its smoke point reaches about 410°F when refined, making it a solid everyday cooking oil across China, Korea, and Japan.
Toasted sesame oil is a completely different ingredient. The seeds are roasted before pressing, which produces a dark, amber oil with an intense nutty, smoky aroma. This version has a lower smoke point and a much stronger flavor, so it’s almost never used for frying. Instead, it works as a finishing oil: a few drops drizzled over congee, rice porridge, noodle soups, or stir-fried vegetables right before serving. Korean cuisine uses it generously in marinades and dipping sauces. A practical rule of thumb is to cook with regular sesame oil and finish with toasted sesame oil.
Soybean Oil: The Quiet Workhorse
Soybean oil doesn’t get much attention, but it’s one of the most consumed cooking oils across Asia and has been for centuries. It has a neutral flavor, a high smoke point (450°F), and it’s inexpensive to produce in regions where soybeans grow abundantly. In China, it’s a default cooking oil for everyday home meals.
In modern commercial kitchens and restaurants, many bottles labeled simply “vegetable oil” are primarily soybean-based. It blends well with other oils, works for everything from deep-frying to dressings, and its neutral taste won’t compete with sauces or spices. If you’ve eaten at an Asian restaurant and the food didn’t taste distinctly of peanut or sesame, there’s a good chance soybean oil was in the wok.
Coconut Oil in Southeast Asian Cooking
Coconut oil has deep roots in the cuisines of Thailand, Malaysia, Indonesia, Singapore, the Philippines, Sri Lanka, and parts of India. In these tropical regions, coconut palms grow abundantly, so coconut oil (along with coconut milk and cream) became a foundation of local cooking long before it became a Western health trend.
It’s used for frying, sautéing, and enriching curries. Unlike the refined, deodorized coconut oil you might find in a Western grocery store, the virgin coconut oil used in traditional Southeast Asian cooking has a noticeable coconut flavor that’s integral to the dish. Sri Lankan curries, for example, rely on coconut oil and coconut cream together to build their characteristic richness.
Ghee in South Asian Cuisine
Ghee, a type of clarified butter traditionally made from buffalo or cow milk, is the defining fat of South Asian cooking. It became central to Indian, Pakistani, and Bangladeshi cuisines centuries ago under Hindu tradition and Mughal rule, where cows were considered sacred and ghee took on spiritual significance. Beyond religion, ghee was practical: clarifying butter removes the milk solids that spoil quickly, giving it a much longer shelf life in warm climates.
Today ghee is everywhere in South Asian food. Street vendors in Delhi deep-fry pakoras and pooris in it. In Karachi and Lahore, freshly baked naan and roti are brushed with ghee as they come off the tandoor. Biryanis in Dhaka are drizzled with it. Festival sweets like laddoos and halwas are loaded with it. Ghee has a high smoke point and a rich, buttery flavor that vegetable oils can’t replicate, which is why it remains the preferred fat even where cheaper alternatives are available.
Regional Specialty Oils
Mustard Oil
Mustard seed oil is a staple in Bengali cooking, where mustard plants thrive in the region’s rich, well-drained soil. It has a pungent, sharp flavor that’s distinctive in Bengali fish curries, pickles, and vegetable dishes. Worth knowing: the U.S. FDA does not permit expressed mustard oil to be sold as a cooking oil because it can contain 20 to 40% erucic acid, a compound that caused heart lesions in animal studies. In the U.S., you’ll often see it labeled “for external use only,” though many South Asian cooks still use it. The essential oil of mustard (a steam-distilled flavoring) is a different product and is considered safe for food use.
Rice Bran Oil
Rice bran oil, extracted from the outer layer of rice grains, is popular in Japan, India, and other rice-producing countries. Its refined smoke point matches peanut and soybean oil at 450°F, and it has a clean, mild taste that works well for tempura and other deep-fried dishes. It’s gained popularity in commercial kitchens for its combination of heat stability and light texture.
Animal Fats
Not all Asian cooking fats come from plants. Lard is used in parts of India with historical Portuguese or French influence, like Goa and Pondicherry. In the mountainous regions of Afghanistan and Bhutan, sheep fat and yak fat are traditional cooking fats, sourced from animals that are already raised for labor, fur, and milk.
What Modern Asian Restaurants Actually Use
Traditional oils are alive and well in home kitchens, but modern Asian restaurants, especially high-volume operations, often rely on cost and practicality. Palm oil is a commercial workhorse with a high smoke point (around 450°F), a long shelf life, and a neutral taste, making it common in fast-paced kitchens for deep-frying. However, nutrition and environmental experts increasingly recommend avoiding palm oil due to its links to rainforest destruction and its less favorable fat profile.
Many restaurants use blended vegetable oils, which are typically soybean-based and chosen for their neutral flavor and low cost. The sesame and peanut oil flavors you taste in restaurant dishes often come from smaller amounts added at the end for flavor, while the bulk cooking happens in these more economical oils. If you’re cooking at home and want authentic results, keeping a bottle of refined peanut oil for high-heat cooking and a small bottle of toasted sesame oil for finishing will cover the majority of East and Southeast Asian recipes.
