An Intro to Chili Oil

An Intro to Chili Oil

Chili oil is a popular condiment around The Spice House, and for good reason. Its savory, aromatic, hot, and complex allure has us spooning it over plates of hummus, bowls of ramen, steamed dumplings, and our morning eggs. It’s also just fun to make, wildly customizable, and simple to prepare. We’ve been playing with a few recipes lately, and are excited to share our kitchen notes with you.


What is Chili Oil?

Chili oil is a condiment made from cooking oil, spices, and chile peppers. It is commonly made with dried, crushed Chinese chiles and Sichuan Peppercorns. Chili oil is especially popular in Chinese and Southeast Asian cuisine, but variations can be found throughout the world.

The simplest way of making chili oil is by adding hot cooking oil to a bowl of crushed, dried chile peppers. The peppers fry and infuse the hot oil, in turn making flavorful oil that can be used in the kitchen and at the table. You can also flavor the hot oil first by simmering it with spices and aromatics. These spices are then strained out before the hot oil is introduced to the dried chiles.

Chili crisp is a close relative to chili oil, with the addition of ingredients such as fried garlic, onion, shallot, and toasted soybeans. This gives it a crunchy, savory texture that doubles its deliciousness as a condiment.


What Spices Are Used in Chili Oil?

Simmering and infusing the oil with spices first adds an essential aromatic component and delicious depth of flavor. This is also where a lot of the customization comes into play, letting you make an oil that reflects your flavor preferences.

Whole spices work best for this step. Chinese and Southeast Asian spices are a great place to start, but there are no set rules to flavoring chili oil. Below you will find a list of popular flavors for infusing oil. In addition to the spices below, you can add fresh ingredients such as garlic bulbs, ginger root, fresh shallots, or galangal root.

Note: Many of these whole spices are strained out before the hot oil is combined with the chile flakes. The final chili oil will be a ready-to-eat condiment. You can also include spices with the chile flakes for the hot oil step, but avoid adding ground spices as they will burn. Try coarser ingredients like Chopped Garlic, Chopped White Onion, or Cracked Black Pepper. Their coarser size allows them to caramelize in the oil, adding a delicious crunch to the final product.

Spices for Infusing Oil:


Other ingredients to consider are salt, sugar, honey, Monosodium Glutamate, vinegar, sesame oil, Black Sesame Seeds, Toasted Sesame Seeds, or White Sesame Seeds. These extra ingredients should be stirred into the oil after the chiles are added and it has cooled to room temperature. You can also stir in one of our premium spice blends for an extra boost of flavor. Try blends such as our Sichuan Chile BBQ Rub, Chinese Five Spice, or Argyle Street Stir Fry Blend.


What Chile Peppers Are Used in Chili Oil?

Much like spices, peppers can be left to your personal preference. Dried Chinese chiles are the most popular for chili oil, and dried red peppers in general tend to work the best. Traditional Chinese and East Asian recipes often call for Tien Tsin Chiles. You can also experiment with chiles like Guajillo Chiles, Chile de Arbol, Aleppo Pepper, and Crushed Red Pepper. To use whole peppers, remove the seeds and stems before crushing them in a mortar and pestle, or blitzing them in a food processor. Try to avoid any ground or powdered chiles when making chili oil. The powder can burn easily and also over-spice the oil.
