Chilli Oil
The Finishing Fire
This is the finishing touch that separates home cooking from restaurant cooking. A spoonful on noodles, fried rice, or dumplings adds that final layer of heat, colour, and fragrance. Most store-bought versions are one-dimensional. This one has layers.
Ingredients
- 1 cup neutral oil (vegetable or peanut, high smoke point)
- 15-20 dried Kashmiri chillies (for colour, mild heat)
- 3 tbsp dried red chilli flakes (gochugaru or standard)
- 1 tbsp Sichuan peppercorns (the numbing element)
- 2 whole star anise
- 1 small cinnamon stick
- 2 bay leaves
- 4 garlic cloves (sliced thin)
- 1 small shallot (sliced thin)
- 1-inch fresh ginger (sliced)
- 1/2 tsp salt
- 1/2 tsp sugar (balances bitterness)
- 1 tbsp toasted sesame seeds
Method
Prep: Set Up Your Station
Cut dried Kashmiri chillies into 1-inch pieces with scissors. Shake out most seeds—this keeps the colour but reduces excessive heat.
In a large heatproof bowl, combine the chilli flakes, salt, sugar, and sesame seeds. This is where the magic will happen.
Slice garlic, shallot, and ginger thin.
Infuse: Build the Flavour Layers
Add oil to a cold wok or saucepan. Add Sichuan peppercorns, star anise, cinnamon, and bay leaves.
Heat over medium-low for 5-6 minutes. The oil should be warm, not smoking. You'll smell the aromatics blooming.
Add sliced garlic, shallot, and ginger. Fry gently for 3-4 minutes until light golden—NOT brown. Brown means bitter.
Add the Kashmiri chilli pieces and fry for 2 more minutes.
Pour: The Critical Step
Remove from heat when oil reaches 180°C (350°F)—or when a flake sizzles immediately when dropped in.
Let oil cool for 30 seconds. This is crucial—it prevents burning the flakes.
Pour hot oil over the chilli flakes in THREE stages:
- First pour (1/3): Listen for the sizzle. Stir.
- Wait 30 seconds
- Second pour (1/3): More sizzle. Stir.
- Wait 30 seconds
- Final pour: Remaining oil. Stir well.
The staged pouring prevents burning and builds flavour layers.
Cool & Store
Let cool completely—this takes about 1 hour.
Transfer to a dark glass bottle. Light degrades the colour and flavour over time. Keeps 3 months at room temperature in a dark cupboard.
Pro Tips
Temperature is Everything
Too hot = burnt and bitter. Too cold = no flavour extraction. 180°C is the sweet spot.
Kashmiri for Colour
They're mild but give that vibrant red. Without them, your oil will be brown and sad.
Don't Skip the Staged Pour
Pouring all at once burns the flakes and creates bitterness. The stages build complexity.
Keep the Sediment
The crispy bits at the bottom are the best part. Scoop them onto everything.

Frequently Asked Questions
Why did my chilli oil turn out bitter?
The oil was too hot when poured over the flakes. Let the oil cool for 30 seconds off the heat before pouring. Pouring at 180°C (350°F) is ideal—any hotter will burn the chilli flakes and create that unpleasant bitter taste.
Can I reuse the strained aromatics?
Yes! The fried garlic, shallots, and ginger are delicious. Chop them up and add to fried rice, noodles, or use as a topping for congee. Some people keep them in the oil—totally a matter of preference.
How do I get more numbing sensation?
Use more Sichuan peppercorns and make sure they are fresh (less than 6 months old). You can also lightly toast them before adding to the oil, or grind some into the finished oil for extra numbing heat.
My oil isn't very red—what went wrong?
You likely didn't use enough Kashmiri chillies. They're the key to that vibrant red colour. Using only regular chilli flakes gives you heat but not the colour. Next time, increase the Kashmiri chillies.
