Sesame Oil substitutes
The best substitute for sesame oil is toasted sesame seeds + neutral oil: Per 1 tsp toasted sesame oil: blitz 1 tsp neutral oil with 1 tsp toasted crushed sesame seeds, then strain. Less concentrated than the bottled oil, so you may need more. Strain it unless you want visible seeds in a smooth dressing.
Why it matters. Toasted sesame oil is a finishing seasoning, not a cooking fat. A teaspoon carries a huge nutty aroma. Leave it out of a stir-fry or dressing and it tastes recognisably incomplete; cook with it over high heat and it turns bitter.
BestToasted sesame seeds + neutral oil
●●●●○Per 1 tsp toasted sesame oil: blitz 1 tsp neutral oil with 1 tsp toasted crushed sesame seeds, then strain
Keeps the flavour and fat roles.

Perilla oil
●●●●○1:1
Keeps the flavour and fat roles.
Nutty and aromatic in a comparable way but grassier and more herbal. Like sesame oil it burns easily, so use it as a finisher.
Walnut oil
●●●○○1:1
Keeps the flavour and fat roles.
Similarly nutty and equally heat-sensitive, but sweeter and less savoury, so an Asian dressing tastes noticeably European. Not nut-free.
Tahini + neutral oil
●●●○○Per 1 tsp: 1/2 tsp tahini whisked with 1/2 tsp neutral oil
Keeps the flavour and fat roles.
Real sesame flavour without the toasted intensity, and it thickens whatever you stir it into. No good as a finishing drizzle.
Chili oil
●●●○○1:1, and cut the chilli elsewhere in the recipe
Keeps the flavour and fat roles.
Many chilli oils have a sesame base, so the aroma is often there, but it adds real heat that sesame oil does not. Check the label.
Peanut oil
●●○○○1:1 as a cooking fat only
Keeps the fat role; loses flavour.
Covers the fat role and nothing else. Toasted sesame oil is a seasoning rather than a cooking fat, so this misses the point of the ingredient. Not nut-free.
