Chinese chili oil is a kitchen staple that adds a fiery kick and rich aroma to countless dishes. Whether drizzled over noodles, dumplings, or stir-fries, this vibrant red oil is beloved for its perfect balance of heat and fragrance. Making your own Chinese chili oil at home is easier than you might think, and it lets you customize the spice level and flavor to your liking. Here’s a friendly, step-by-step guide on how to make authentic Chinese chili oil from scratch.
What Is Chinese Chili Oil?
Chinese chili oil (辣椒油, là jiāo yóu) is a spicy condiment made by infusing neutral oil with dried chili peppers and aromatic spices. The oil captures the heat of the chilies and the fragrance of spices like star anise, Sichuan peppercorns, garlic, and ginger. The result is a versatile, flavorful oil that enhances everything from soups to stir-fried vegetables.
Ingredients You’ll Need
To make classic Chinese chili oil, gather the following:
– Neutral oil with a high smoke point (such as vegetable, canola, or avocado oil) – about 2 to 3 cups
– Dried red chili flakes or whole dried red chilies (Sichuan red chilies are ideal) – about 1.5 cups flakes or 2 cups whole chilies
– Aromatic spices: star anise, cinnamon stick, bay leaves, cloves, Sichuan peppercorns
– Fresh aromatics: garlic cloves (smashed), ginger slices, shallots or onion
– Salt and sugar for seasoning
– Optional: toasted sesame seeds for added texture and flavor
Step-by-Step Instructions
1. Prepare the Chili Flakes
If you’re using whole dried chilies, grind them into flakes using a food processor or spice grinder. Be careful not to inhale the chili dust, as it can be irritating. Transfer the chili flakes to a large, heatproof bowl made of ceramic, glass, or metal. Add minced garlic, a pinch of Sichuan pepper powder, and salt to the bowl, then set aside.
2. Infuse the Oil with Aromatics and Spices
Pour your neutral oil into a heavy-bottomed saucepan. Add whole spices such as star anise, cinnamon, bay leaves, cloves, and Sichuan peppercorns, along with fresh aromatics like garlic, ginger, and shallots. Heat the oil gently over low to medium heat, maintaining a temperature around 225-250°F (107-121°C). Let the spices and aromatics simmer slowly for 20 to 30 minutes, or until they turn golden and fragrant. This slow infusion releases deep flavors without burning the ingredients.
3. Strain the Oil and Heat to Higher Temperature
Once infused, strain the oil through a fine mesh strainer to remove the solids. Return the clear, flavored oil to the saucepan and heat it up to about 350°F (175°C). This higher temperature is important for the next step, where the oil will be poured over the chili flakes.
4. Pour Hot Oil Over Chili Flakes
Carefully pour the hot oil over the chili flakes in your heatproof bowl. The oil will bubble and sizzle as it cooks the chili flakes, releasing their vibrant color and heat without burning them. Stir gently to ensure even cooking and to prevent the flakes from scorching.
5. Add Final Seasonings and Cool
Once the oil has cooled slightly, stir in toasted sesame seeds, sugar, and adjust salt to taste. Let the chili oil cool completely before transferring it to a sterilized glass jar with an airtight lid. This homemade chili oil can be stored in the refrigerator for up to 3 to 6 months.
Expert Tips for Perfect Chili Oil
– Use whole dried chilies when possible for more aromatic and flavorful chili flakes. Pre-ground flakes are convenient but less fragrant.
– Maintain the oil temperature carefully—too low and the oil won’t extract enough flavor, too high and the chili flakes will burn, resulting in bitterness.
– Use a digital instant-read thermometer to monitor oil temperature for best results.
– Fry aromatics low and slow to avoid bitterness and to deepen flavor.
– Always use a heatproof bowl for the chili flakes to prevent cracking or melting when pouring hot oil.
– Use clean utensils when scooping chili oil to prevent contamination and mold growth.
