How to Cook with Chili Oil

Cook with chili oil two ways: as a cooking fat you fry things in, or as a finishing oil you drizzle over food just before serving. It adds smooth heat and a savory, aromatic depth — with no crunch, just flavor. Use it anywhere you'd use olive oil for added heat: sautéing vegetables, frying eggs, tossing noodles, pouring over soups, or whisking into dressings.

This guide uses our Chili Oil — made with avocado oil instead of seed oils, small-batch, Asheville, NC. It is a smooth, pourable oil, not a chili crisp.

Chili oil vs chili crisp: the quick distinction

Chili oil is smooth and pourable — all heat and flavor, no crunch. Chili crisp is chunky with fried aromatics — it adds texture as well as heat. If you want crunchy bits in your food, reach for the crisp. If you want clean, smooth heat as a cooking fat or finishing drizzle, reach for the oil. See the full chili crisp collection or the chili oil page.

How to use chili oil in cooking

As a cooking fat (frying & sautéing)

• Frying eggs — a tablespoon in the pan makes crispy-edged eggs with subtle heat. (For extra crunch on top, finish with chili crisp.)
• Sautéing vegetables — use in place of olive oil to build heat in the pan before adding veg.
• Stir-fries — add at the start or finish to carry flavor through the whole dish.
• Pan sauces — deglaze with a little broth after using chili oil, and the heat carries into the sauce.

As a finishing oil (drizzle)

• Noodles — toss hot noodles with a tablespoon for fast flavor. See our full chili oil noodles recipe.
• Soups & ramen — swirl a teaspoon over the bowl just before eating.
• Dumplings & wontons — pour a little pool alongside as a dipping sauce.
• Roasted vegetables — drizzle over veg as they come out of the oven.
• Hummus & dips — finish the top of a hummus bowl for color and heat.
• Bruschetta & toast — drizzle over ricotta toast or grilled bread.

In sauces & dressings

• Whisk into vinaigrettes in place of or alongside neutral oil.
• Stir into peanut sauce, sesame noodle sauce, or tahini dressing for heat.
• Use as the base fat in a stir-fry sauce before adding soy sauce and vinegar.

In marinades

• Use as the oil component of a marinade for chicken, shrimp, tofu or fish — the heat infuses as it marinates.

How much chili oil to use

• Finishing drizzle over a bowl: 1–2 teaspoons
• Cooking fat for sautéing or frying: 1 tablespoon per serving
• Into a dressing or sauce: start with 1 teaspoon and taste up

Storing chili oil

Store at room temperature away from direct heat and light. Always replace the cap tightly. Refrigeration is optional but safe — it won't change the oil, just thicken it slightly. Let it come to room temperature before pouring if it thickens.
