Light vs. Toasted: Know Your Oil
The first and most crucial lesson in cooking with sesame oil is knowing which type to use. Light (or unrefined) sesame oil is cold-pressed from raw seeds, resulting in a pale, golden colour and a mild, nutty flavour. This is your go-to for general cooking, as it can handle some heat and imparts a subtle richness.
Toasted sesame oil, on the other hand, is made from seeds that are roasted before pressing, giving it a dark amber colour and a powerful, intense aroma. This type is not a cooking oil but a finishing oil. Using toasted sesame oil over high heat will burn its delicate compounds, creating a bitter, unpleasant taste and destroying its wonderful aroma.
The All-Important Smoke Point
The smoke point is the temperature at which an oil stops shimmering and starts smoking, breaking down and releasing harmful compounds. Using an oil above its smoke point is unhealthy and ruins the flavour of your food. Light, unrefined sesame oil has a medium smoke point, around 177°C (350°F), making it perfect for sautéing and low-heat stir-frying.
For high-heat cooking like deep-frying, a refined oil (with a smoke point over 230°C or 445°F) is necessary. However, remember that refinement strips the oil of its nutrients and flavour. Therefore, for most everyday cooking, the gentle heat suitable for cold-pressed sesame oil is ideal for preserving both health benefits and taste.
Pros and cons of Cooking with Unrefined Sesame Oil
Pros
- Adds a rich, nutty flavour and aroma to dishes.
- Retains beneficial nutrients like antioxidants and Vitamin E.
- Extremely versatile for dressings, marinades, and light sautéing.
- A little goes a long way, especially for finishing.
Cons
- Lower smoke point makes it unsuitable for high-heat frying or searing.
- Its distinct flavour may not be suitable for all types of cuisines.
- Can easily overpower a dish if too much is used.
- Quality cold-pressed versions can be more expensive than standard vegetable oils.
Mastering Flavour Pairings
Sesame oil is a team player, known for its ability to harmonize with and elevate other ingredients. Its most famous partners are soy sauce, ginger, and garlic, creating the foundational flavour base for countless Asian dishes. This combination provides a perfect balance of savory, aromatic, and pungent notes.
But don’t stop there. The nutty sesame oil flavor also pairs beautifully with honey or maple syrup for a sweet-and-savory glaze, with rice vinegar and lime for a tangy dressing, or with chili flakes for a touch of heat. It’s a fantastic way to add depth to roasted vegetables, noodle salads, and marinades for tofu or chicken.
Simple Recipes to Showcase Sesame Oil
The best way to appreciate sesame oil is to let it shine in simple preparations. For a quick and delicious vinaigrette, whisk together 2 tablespoons of light sesame oil, 1 tablespoon of rice vinegar, 1 tablespoon of soy sauce, and 1 teaspoon of honey. This sesame oil vinaigrette is perfect for a simple green salad or a cold noodle salad.
For a basic stir-fry sauce, combine light sesame oil with minced garlic and ginger in a pan over medium heat until fragrant. Add your vegetables or protein, then finish with a splash of soy sauce. Right before serving, turn off the heat and drizzle with a tiny amount of toasted sesame oil for that incredible, aromatic finish.
Key Terms Explained
- Smoke Point: The temperature at which an oil begins to burn and produce smoke, indicating it’s breaking down.
- Finishing Oil: An oil added to a dish after cooking is complete, primarily for its intense flavour and aroma rather than for cooking.
- Sautéing: A cooking method that uses a small amount of oil or fat in a shallow pan over relatively high heat.
- Emulsify: The process of combining two liquids that don’t normally mix, like oil and vinegar, into a smooth dressing.
Storing Your Oil for Maximum Freshness
Like all high-quality, unrefined oils, sesame oil is sensitive to heat, light, and air, which can cause it to go rancid. To protect its flavour and nutritional integrity, proper storage is essential. Always keep your bottle of pure sesame oil tightly sealed to minimize its exposure to oxygen.
The best place to store it is in a cool, dark place, like a pantry or cupboard, away from the stove or any other heat sources. While you can refrigerate it to extend its shelf life further, the oil may become cloudy and thick; simply let it return to room temperature before using.

Frequently Asked Questions
Can I use toasted sesame oil for frying?
No, you should not use toasted sesame oil for frying or high-heat cooking. It has a very low smoke point and will burn quickly, resulting in a bitter taste and harmful compounds. Use it as a finishing oil after cooking is complete.
Is sesame oil healthier than olive oil?
Both are very healthy oils, rich in unsaturated fats. Sesame oil is particularly high in omega-6 fatty acids, while olive oil is high in omega-9. They offer different antioxidant profiles and health benefits, so including a variety of unrefined oils in your diet is best.
How can I tell if my sesame oil has gone bad?
Rancid sesame oil will have a distinctly unpleasant, bitter, or metallic smell, unlike its usual fresh, nutty aroma. If it smells off, it’s best to discard it, as it will ruin the taste of your food.
How long does sesame oil last once opened?
When stored properly in a cool, dark place, an opened bottle of unrefined sesame oil should last for about 6 to 12 months. Refrigerating it can extend this, but it’s not necessary if used regularly.
What is a good substitute for light sesame oil in a recipe?
If you need a substitute for light sesame oil for cooking, other neutral oils with a similar medium smoke point, like canola oil, grapeseed oil, or a light olive oil, will work in terms of function, but you will miss out on the specific nutty flavour.
