What is Chili Oil and How to Make It at Home?
Chili oil is an infused oil that carries the heat and flavor of dried chilies. Commonly found in Asian cuisines, this homemade version allows you to adjust the spiciness according to your preference.
The process is rewarding, and you’ll end up with a delicious oil for various dishes.
Why Does This Recipe Work?
Here are four solid reasons why you’ll love making chili oil at home:
- Personalized Heat Level: You control the spice! Start with mild chili flakes and progressively work your way up to the hottest varieties. When I first made my chili oil, I wished for something milder. Adjusting the chili flakes made all the difference in my next batch.
- Quality Control: You know exactly what goes into your oil. Opt for high-quality ingredients and avoid any preservatives. Once, I went for a store-bought version, and the flavor just didn’t compare. My oil was fresher, with taste and depth that store-bought couldn’t match.
- Fresh Ingredients: Homemade chili oil has a palette of flavors that can only come from fresh ingredients. Dried chilies, aromatic spices, and herbal notes combined create a fragrant oil. I remember that first whiff—smoky, slightly sweet, and oh-so-delicious.
- Easy Storage: You can keep it for use later on! Chili oil stores exceptionally well in a dark bottle. It gets better as it ages, which makes it perfect for meal prep. What’s better than having a jar ready for those last-minute cooking needs?
Ingredients You’ll Need To Make Chili Oil at Home
You’ll need the following ingredients to whip up this fiery delight:
- 1½–3 cups neutral oil (like canola or vegetable oil for frying)
- 3 tablespoons Sichuan peppercorns
- ¾ to 1¼ cup Sichuan chili flakes
- 5 whole star anise
- 1 cinnamon stick (preferably cassia cinnamon)
- 2 dried bay leaves
- 2 black cardamom pods (optional)
- 2 teaspoons whole cloves (optional)
- 1–2 shallots (optional – halved)
- 3 garlic cloves (optional – crushed)
- 1 tablespoon ginger slices (adds a certain warmth)
- 4 small pieces dried sand ginger (optional)
- 1–2 teaspoons sea salt (to taste)
- 1 teaspoon fennel seeds (adds subtle sweetness)

How To Make Chili Oil
Let me walk you through the steps! Making chili oil is as enjoyable as it is easy. Just follow these clear instructions.
Step 1: Gather Materials
Before diving in, gather all your ingredients and tools. You’ll need a heavy-bottomed pot, a heat-resistant bottle or jar for storage, and a fine-mesh sieve or cheesecloth for straining.
Step 2: Heat the Oil
In your heavy-bottomed pot, pour in the neutral oil and heat it over a medium flame. Use enough oil to submerge the ingredients. You’ll want it hot but not smoking—about 300°F (150°C). If you don’t have a thermometer, just watch for small bubbles as it warms up.
Step 3: Toast the Spices
Once the oil is hot, add the Sichuan peppercorns, star anise, bay leaves, and the other whole spices. Let the spices gently sizzle and infuse the oil. Keep it on low heat for about 5–10 minutes. Be careful not to burn them! The aroma will begin to fill your kitchen.
Step 4: Add Chili Flakes and Aromatics
After the spices have toasted, turn off the heat. Stir in the Sichuan chili flakes. This is where the heat truly develops. If you’re adding shallots, garlic, or ginger, toss them in at this point. They’ll steep and release their flavors and aromas. Let everything steep for about 10–15 minutes.
Step 5: Strain and Store
After steeping, strain the chili oil through a fine-mesh sieve or cheesecloth into your clean bottle or jar. Discard the solid spices, and let the oil cool down to room temperature. Seal the jar and store it in a cool, dark place.
Tips for Making Perfect Chili Oil
Here are some tips to ensure your chili oil turns out just right:
- Quality of Ingredients: Opt for high-quality dried chilies and whole spices. The better the quality, the tastier the oil.
- Adjusting Spice Level: If you’re unsure about the spice level, start with less chili and gradually increase as needed.
- Avoid Overheating: Do not let the oil smoke. If it starts to smoke, it will impart a burnt flavor to your oil.
- Customize Flavors: Feel free to add herbs or other aromatics based on your taste. Have fun experimenting!
- Storage Matters: Always store your chili oil in a dark bottle. Light can degrade the flavor and quality over time.

How to Store Leftovers
Chili oil can be stored in your pantry. Just make sure to keep it in an airtight container. It should last for 2–3 months, though the flavors will probably develop over time.
You might find that the spiciness intensifies. Keep an eye (and nose) on it, and toss it if you ever detect any off smells.
Recommended Side Dishes for Chili Oil
Here are some amazing dishes to pair your homemade chili oil with:
- Steamed Dumplings: Almost a match made in heaven, the chili oil provides a flavorful dip for dumplings.
- Noodle Dishes: Whether it’s ramen or soba, a drizzle of chili oil will kick it up a notch.
- Roasted Vegetables: Toss veggies like asparagus or broccoli in chili oil before roasting. The heat caramelizes beautifully.
- Savory Pancakes: Add chili oil to the batter or serve it as a condiment with savory pancakes. Those pancakes will be incredibly satisfying.
Substitute Options for Ingredients
If you find yourself missing some ingredients, don’t fret! Here are some substitutes:
- Neutral Oil: Canola or sunflower oil works if you don’t have neutral oil. Olive oil also works but will impart its own flavor.
- Sichuan Peppercorns: In a pinch, use regular black pepper or a blend of black and white peppercorns.
- Chili Flakes: If you can’t find Sichuan chili flakes, crushed red pepper flakes are a reasonable alternative.
- Whole Spices: If you lack specific whole spices, like star anise or fennel seeds, consider omitting them or using what you have on hand.
