How to Make Chili Oil at Home
Chili oil is fundamentally oil infused with heat, aromatics, and — crucially — texture. The commercial chili crisps that have swept American kitchens in the past five years are just well-made versions of a technique that's been standard in Sichuan and other Asian kitchens for centuries. The bloom method — pouring hot oil over dried chilis and aromatics — is simple and produces results that are hard to match from a jar.
Prepare your aromatics
Combine in a heat-proof bowl: 3 tablespoons Korean chili flakes (gochugaru), 1 tablespoon Chinese dried chili flakes, 1 teaspoon ground Sichuan pepper, 2 teaspoons sesame seeds, 1 teaspoon garlic powder, ½ teaspoon salt, 1 teaspoon soy sauce. Mix well.
Choose your oil
Neutral oil with a high smoke point: grapeseed, avocado, or refined sunflower. You need 1 cup. Avoid olive oil — the low smoke point creates bitter compounds at bloom temperature, and the flavor competes.
Heat the oil
Heat oil in a saucepan to 325–350°F. Use a thermometer — below 300°F and you don't bloom the aromatics properly; above 375°F and you burn them. A cube of ginger dropped in should sizzle immediately but not violently.
The bloom
Pour the hot oil over your aromatics in a thin stream, stirring constantly. The mixture will foam and sizzle — this is the bloom. The heat activates the chili compounds, toasts the sesame seeds, and creates the deep red-orange color. Let it settle for 30 seconds.
Add texture (optional)
For chili crisp texture: fry ¼ cup thinly sliced shallots and 4 cloves sliced garlic in the oil before pouring. Fry until golden and crisp, remove with a slotted spoon, drain on paper towels, then add back to the finished oil.
Pro tips
- —Let the oil cool to room temp before sealing — hot oil in a sealed jar can create pressure
- —Refrigerated, it keeps for 2 months; the flavors deepen significantly after 48 hours
- —A small piece of cinnamon stick or a star anise added to the aromatics adds complexity without being identifiable
- —Drizzle over dumplings, fried eggs, noodles, pizza, or anything that needs heat and richness
