What Is Chili Oil?
Learn what Chinese chili oil is, what it tastes like, how to use it in noodles, dumplings, sauces, and stir-fries, and how it differs from chili crisp.
Chili oil is a Chinese seasoning made by infusing hot oil with dried chilies and often spices such as Sichuan peppercorn, star anise, bay leaf, cinnamon, garlic, or sesame seeds. It adds heat, color, aroma, and richness to dishes.
It is used in noodles, dumpling sauces, cold dishes, soups, stir-fries, tofu dishes, and dipping sauces.
Quick Answer
Chinese chili oil is oil infused with dried chili flakes and aromatics. It can be mild, smoky, spicy, or numbing depending on the ingredients. Use it as a finishing oil, sauce base, or dipping sauce ingredient.
What Does Chili Oil Taste Like?
Chili oil tastes spicy, aromatic, and rich. Some versions are smoky and red, while Sichuan-style versions may include a numbing fragrance from Sichuan peppercorns.
The oil carries flavor across the dish, so even a small spoonful can make noodles or dumplings taste fuller.
Chili Oil vs Chili Crisp
Chili oil is usually more oil-forward, with chili flakes settled at the bottom. Chili crisp has more crunchy bits such as fried garlic, shallots, soybeans, or peanuts.
They can sometimes replace each other, but chili crisp adds texture and often more seasoning.
How Chili Oil Is Used In Chinese Cooking
Use chili oil in dumpling dipping sauce, cold noodles, hot noodle soups, wontons, cucumber salad, tofu dishes, and simple rice bowls.
It is often mixed with soy sauce, black vinegar, garlic, sesame oil, sugar, and scallions. Add it near the end so the aroma stays bright.
Is Chili Oil Always Very Spicy?
No. Some chili oils are more aromatic than hot. Heat depends on the chili type and how much chili sediment you use.
If you want less heat, spoon mostly the red oil from the top. If you want more heat and texture, stir the jar and include the chili flakes.
Best Chili Oil Substitute
Use chili crisp when texture is welcome. For a cleaner substitute, warm neutral oil with chili flakes briefly, then let it cool before using.
In a pinch, use a small amount of chili garlic sauce or dried chili flakes, but the texture and aroma will differ.
How To Store Chili Oil
Store chili oil according to the label. Keep homemade chili oil refrigerated if it includes fresh garlic, fresh aromatics, or moisture. Use clean utensils and discard it if it smells off or grows mold.
