When I’m in a rush, I’ll pour some oven avocado toast and eggs. For cozier days, it finishes a bubbling pot of gumbo. And when I want to elevate my Perfect Dumpling Sauce, just a quick drizzle of this homemade chili oil brings it to life with deep, molten heat.

What truly matters is the detail—the steps, the ingredients, and how you tweak each part to suit your taste. Over time, I’ve answered dozens of questions about making it just right. My dad gave me the first tip: toast the spices slowly.

My sister once added star anise, and we both just stared at the pan, unsure if we’d gone too far—but it turned out incredible.

Whether it’s spooned over fried rice, mixed into noodle bowls, or served beside bao or dumplings, this chili oil always transforms the dish. Try it with a crunchy chili crisp or whisked into vinaigrettes—you’ll start seeing how flexible and flavor-packed it really is.

What is Chili Oil?

Chili oil is a simple yet versatile creation made by infusing vegetable oil with your favorite chili peppers—whether you prefer a mild heat or the fiery kick of superhot varieties. This type of oil is all about flexibility, allowing you to choose the ingredients that suit your choice.

A neutral oil works best to truly highlight the bold, smoky flavor of the chili peppers. While the ingredients included may vary, the essence remains the same: a rich, aromatic base that elevates any dish. With the right balance, you can craft an ideal oil tailored to your taste buds.

Best Oil for Making Chili Oil

When making the best homemade chili oil, I always start with a neutral oil—something that lets the chili’s natural heat and aroma shine. Oils like peanut oil, canola oil, corn oil, avocado oil, or vegetable oil are ideal. These are all high smoke point oils that won’t interfere with the core flavor profile. From my own kitchen trials, peanut oil has given me the most consistent results, especially when I want a clean, toasty finish that carries the spice without clouding it.

Now, if you’re tempted by olive oil, sesame oil, or even coconut oil, I get it—I’ve tried them too. But be prepared: these oils have strong, distinct flavors that can compete with the chili and aromatics, sometimes shifting the entire dish. That said, it’s not wrong to experiment. If you love bold, nutty, or tropical notes, you might find your signature blend.

In the end, the right oil depends on how you plan to use your chili oil. Are you drizzling it over noodles, spooning it onto dumplings, or folding it into dressings? Choose the base oil that best supports the role it’ll play in your dish. I’ve learned that understanding your goal helps you pick smarter—and cook better.

Chili Oil Recipe Ingredients

When making chili oil, you need the right ingredients for a balanced and flavorful result. Here’s a breakdown of what you’ll need and some helpful details:

  • Oil: A neutral oil like canola, vegetable, or soybean is ideal as it won’t overpower the flavors. If you want to add a twist, try avocado oil, but be mindful that it can harden in the refrigerator. Light olive oil is also a good option, but it has a lower smoke point and may harden when chilled.
  • Essential Spices:
    • Star anise
    • Cinnamon stick (preferably cassia cinnamon)
    • Bay leaves
    • Sichuan peppercorns

These spices create the aromatic base of your chili oil

  • Sichuan Chili Flakes: For the best flavor and heat, use Sichuan chili flakes rather than regular red pepper flakes. This is key for an authentic taste!
  • Optional Add-ins: You can add extra spices and aromatics to elevate the flavor profile:
    • Black cardamom (also known as cǎoguǒ)
    • Cloves
    • Dried sand ginger
    • Fresh garlic or shallots for a richer infusion
  • Additional Flavor Boosters: To round out the taste, consider adding:
    • Soy sauce
    • Chinese black vinegar
    • Toasted sesame seeds
    • Sesame oil
  • Salt: Essential to bring out the full depth of flavor from all the spices.

How Much Oil to Use?

  • For a lighter chili oil with fewer aromatics, you’ll need about 1½ cups of oil.
  • For a richer, bolder flavor with more aromatics, aim for about 3 cups.

Adjust the quantities to your liking, but remember, a little experimentation can lead to the perfect flavored chili oil for your dishes!

How to Make Chili Oil Recipe

Making chili oil at home is easier than most people think. With a bit of patience and a few smart steps, you’ll create a jar full of spicy, aromatic oil that can level up everything from noodles to eggs. After spending years perfecting this process in my own kitchen, I’ve developed a method that’s both simple and deeply flavorful.

Step 1: Prepare Aromatics

Start by laying out your spices: cassia cinnamon, cloves, fennel seed, bay leaves, and black cardamom.

These aren’t just for heat—they build a rich, fragrant base. I often add bai dou kou, plus fresh crushed garlic and sliced shallots—sometimes even scallions if I have them on hand. These aromatics are essential for creating layers of depth.

The first time I skipped fennel seed, I noticed the difference—it really does matter.

Step 2: Heat the Oil

Combine the aromatics with your neutral oil in a heavy pot. Heat slowly over medium-low.

Use a Thermapen® ONE or an infrared thermometer to stay accurate. You want the oil between 225°F and 250°F—hot enough to draw out the flavors, but not so hot that the garlic burns or the spices turn bitter.

Listen for that soft sizzle and sniff for that toasty, popcorn-like aroma—it’s how I always know I’m on the right track.

Step 3: Infuse and Strain

Let the oil gently infuse for 30 minutes to an hour. I usually check around the 45-minute mark. Once the shallots and other aromatics start turning golden and have given off their flavor, take them out.

Strain the oil through a fine-mesh sieve. Keeping it smooth and clean helps the chili oil last longer and blend beautifully into dressings or dips.

Step 4: Combine with Chili Flakes

Place your chili flakes in a heatproof bowl—you can pick a bright red or a deep red depending on your flavor preference.

Carefully pour the hot oil over the flakes while stirring. It should sizzle—this part always reminds me of my sister leaning over the bowl, wide-eyed, the first time she helped me.

Finish with a pinch of salt, and if you want to level it up, add some lightly toasted sesame seeds, or a splash of soy sauce and black vinegar for a more complex flavor profile.

Advice on Making Chili Oil

Mastering chili oil isn’t just about mixing ingredients—it’s about balancing heat, aroma, and technique. Whether you’re inspired by creators like Mikey Chen or crafting your own spicy blend, these real-world tips come from experience—and they’ll help you get it right the first time.

Techniques and Tips

Start with a heavy-bottomed wok or saucepan. It helps the oil heat evenly, which matters more than you might think. Always use low to medium heat—too hot, and you’ll burn your spices, leaving a bitter taste. I’ve made that mistake once during a rushed dinner party prep and regretted it instantly.

Add pre-toasted spices like Sichuan peppercorns to build a layered, fragrant base. When you stir in your chili oil crisp flakes, make sure the oil is hot enough for them to bloom, but not smoke. Keep your eye on the timing—don’t go past 30 minutes, and try to keep a steady heat throughout.

When it comes to choosing peppers, think about flavor and spice level. I often use a mix—Thai chilis, Ghost Peppers, or Jalapeños for serious heat, and xiao mi la to round out the flavor. You can grind them coarsely or fine—it depends on the texture you’re aiming for. I always divide my oil into small batches to avoid overheating and to keep control over each step.

Storage and Safety

Once your chili oil is ready, let it cool completely. Then pour it into airtight, heat proof containers. If I’m making a big batch, I label and refrigerate a few jars to keep the flavor fresh longer. Sterilizing your tools—especially jars and utensils—is a simple step, but it prevents spoilage and ensures your oil lasts for weeks. Stored properly, your homemade oil can easily match or beat anything from the store—both in taste and shelf life.

Whether you’re trading tips in forums like r/ChineseCooking or following leads from trusted voices on platforms like Linity, these steps will help you create chili oil that’s balanced, bold, and deeply flavorful every time.

Frequently Asked Questions

Expand All:
How do you infuse fresh ingredients into chili oil?

To make your chili oil extra flavorful, you can infuse fresh ingredients like garlic, ginger, shallots, and red onion into it. First, heat your oil and carefully fry these fresh ingredients until they’re thoroughly cooked. You can even add a bay leaf or other popular ingredients during this step, but be cautious not to let them burn. Once everything is cooked, scoop out the solids and pour the infused oil over your chili mix. Remember, there should be no more fresh solids in the oil before you move it to storage. This process helps create a rich oil infusion that brings out amazing flavors in your chili oil.

What type of chili do you use to make chili oil?

Crafting the perfect chili oil starts with choosing the right chilies to match your desired taste. For a traditional Sichuan kick, I recommend dried chili flakes paired with Sichuan red peppercorns for that signature numbing sensation. If you prefer something milder, like a Cantonese style, stick to chilies that balance mild heat with flavor. For a burst of fresh heat, try infusing jalapeños or serrano peppers into your oil. Want to explore? Experiment with Korean red pepper flakes for a unique twist. Just remember, spicy fumes can be intense—crack open a window while cooking, and feel free to change things up to create your perfect blend.

How do you adjust the spiciness of chili oil?

Adjusting the spiciness is as simple as increasing or decreasing the ratio of chili flakes to the other ingredients and oil during cooking. For a gentler flavor, let the chili oil sit for a longer time—it naturally mellows out as it rests safely in the fridge. My personal tip? Start mild and adjust heat to your liking over time; this approach lets you refine the boldness of your oil with every batch.

How do you store chili oil?

Chili oil should stay in the fridge. This is especially true of homemade chili oil, since we don't add any preservatives.

To help it stay fresh, make sure to use a clean, dry spoon each time you scoop into it. Or, you can use a bottle to pour the oil out. The point is to avoid introducing water or other contaminants into the chili oil.

How long does homemade chili oil last?

When you keep homemade chili oil in the fridge, it can stay fresh for months! Just remember to check it from time to time—if you notice mold or anything unusual, it’s better to toss it all out to be safe. Proper storage, like keeping it cool and sealed, ensures your chili oil stays delicious and ready to add that extra kick to your meals.
