Making Chili Oil
This is a pantry staple that relies on timing rather than complex equipment. A good batch balances the bite of the peppers with the deep fragrance of toasted spices.
Watch the oil temperature, not the clock.
Oil heats quickly and stays hot longer than you expect; if the flakes turn black instantly, the oil was too hot.
- heavy-bottomed saucepan
- thermometer
- heat-proof glass jar
- fine-mesh strainer (optional)
What goes in.
- 1.5 cupsneutral oil (grapeseed or canola)
- 1/2 cupcoarse red chili flakes
- 3 tbspgarlic, minced
- 1 tspSichuan peppercorns, toasted and crushed
- 1star anise pod
- 1 tspsea salt
Control the heat extraction
Pouring oil at 350°F ensures the spices bloom and the garlic turns golden brown, but it requires a heat-proof vessel to prevent cracking.
The method.
Prepare the base
Place the chili flakes, garlic, crushed peppercorns, and salt into a heat-proof glass jar. Give them a stir so they are evenly distributed.
Infuse the oil
Add the oil and star anise to your saucepan. Heat over medium until the oil reaches 350°F. If you lack a thermometer, drop one chili flake into the oil; if it bubbles steadily and turns vibrant red within seconds, it is ready.
The infusion
Remove the star anise. Carefully pour the hot oil into the jar. It will bubble aggressively—this is normal.
Cooling
Let the oil sit uncovered until it reaches room temperature. The garlic will finish softening in the residual heat, turning a pale gold.
Other turns to take.
Ginger Infused
Add a one-inch piece of smashed ginger to the oil while heating, then remove before pouring.
Deep Smoke
Replace one tablespoon of standard chili flakes with smoked paprika for a darker, earthier depth.
When it doesn't go to plan.
Use a glass or ceramic container; plastic will warp or melt when the hot oil hits.
If you prefer a clear oil without the grit, wait for the oil to cool completely before straining it through a fine-mesh sieve.
Store in a cool, dark place to keep the chili flakes from losing their vibrant red hue.
The ones that keep coming up.
How do I know if the oil is too hot?
If the chili flakes turn black or smell like burning rubber immediately upon contact, the oil exceeded 400°F.
Does it need to be refrigerated?
Stored in an airtight jar, it keeps at room temperature for several weeks, though refrigeration will extend its shelf life.
