How Do You Make Hot Chili Oil? A Simple Guide to Spicy Perfection

If you love adding a fiery kick to your meals, learning how to make hot chili oil at home is a game changer. This vibrant condiment is a staple in many Asian kitchens and can elevate everything from noodles to stir-fries and even salads. Plus, making it yourself means you control the heat level and flavor, avoiding preservatives and additives found in store-bought versions.

Let’s dive into an easy, foolproof method to create your own hot chili oil that’s bursting with flavor and just the right amount of heat.

What Is Hot Chili Oil?

Hot chili oil is essentially dried chili flakes infused in oil, creating a spicy, aromatic oil that adds depth and warmth to dishes. The key is to heat the oil just right so it releases the chili’s flavor without burning it, which can cause bitterness. Different chili varieties bring unique flavors—from sharp heat to smoky undertones—so you can customize your oil to your taste.

Ingredients You’ll Need

– Neutral oil (canola, peanut, or grape seed oil) – about 1 cup

– Dried chili flakes or crushed dried chili peppers – 3 tablespoons (adjust to heat preference)

– Salt – a pinch (optional, enhances flavor)

– Aromatics (optional but recommended): star anise, cinnamon sticks, cloves, bay leaves, sesame seeds, garlic, or ginger slices

Step-by-Step Guide to Making Hot Chili Oil

1. Prepare Your Aromatics and Chili Flakes

Start by placing your chili flakes and any dry spices or aromatics you like into a heatproof bowl or jar. Ceramic or Pyrex glass works well because they can handle the hot oil. If you want a simple oil, just chili flakes and salt will do, but adding spices like star anise or cinnamon can elevate the flavor.

2. Heat the Oil Carefully

Pour your neutral oil into a small saucepan and heat it over medium heat. Use a thermometer if you have one—the ideal temperature is around 300°F to 375°F (150°C to 190°C). The oil should be hot enough to sizzle the spices but not so hot that it smokes or burns them. If you don’t have a thermometer, watch for tiny bubbles around a piece of ginger or garlic to gauge the heat.

3. Infuse the Oil with Aromatics

Add your whole spices and aromatics (like star anise, cinnamon, cloves, or ginger slices) to the hot oil. Let them gently simmer for about 15 minutes, stirring occasionally, so the oil absorbs their fragrance. Keep the heat moderate to avoid burning the spices.

4. Pour the Hot Oil Over the Chili Flakes

Once your oil is infused and aromatic, carefully strain out the whole spices if you used them. Then, slowly pour the hot oil over the chili flakes in your bowl. The oil will bubble and sizzle as it cooks the chili flakes, releasing their smoky, spicy flavor. Stir the mixture to combine everything evenly.

5. Let It Cool and Store

Allow your chili oil to cool to room temperature. Once cooled, transfer it to a clean glass jar with a tight lid. The oil will keep in the refrigerator for several weeks or even months. The flavor will deepen over time, and the heat may intensify as the chili flakes continue to infuse.

Tips for Perfect Hot Chili Oil

Choose your chili flakes wisely: Thai red chilies give sharp heat, while Ancho or Korean chili flakes add smokiness. Mix and match to find your favorite.

Don’t overheat the oil: Burning the chili flakes or spices creates bitterness that ruins the oil’s flavor. Keep an eye on the temperature.

Add extras for complexity: Garlic powder, white pepper, sesame seeds, or even peanuts can add texture and flavor.

Use heat-resistant containers: Pouring hot oil into non-heatproof glass can cause cracking or shattering—ceramic bowls or Pyrex glass are safer.

Test your oil before use: Fresh chili oil is milder, but it gets spicier with time. Start with a small amount when adding to dishes.
