Chinese hot oil aka spicy chili oil or 辣椒油/红油 in Chinese is a chili infused oil and a fundamental condiment used in many Chinese dishes.

And for those of you in the know, it’s the soul to a lot of spicy dishes found in Sichuan region.

Wonder why the Dan Dan noodle is better at a particular restaurant? It’s probably because they have better chili oil! Why is the beef noodle soup lacking the kick? It’s probably because the chili oil is stale. And I can list many more examples but you get the drift.

Hot oil is an essential ingredient regions like Sichuan, Hunan, and Yunnan where hot and spicy food is dominant and a lot of families make their own hot oil from scratch on weekly basis.

Spicy hot oil is reasonably easy to make. The most basic hot oil recipe is just to combine the heated oil and chili.

When I was growing up in Chongqing, then a part of the Sichuan province, my parents always conveniently kept a big jar of homemade chili oil on our dining table as a table condiment.

To me, chili oil was more than just a condiment but a magic potion that could turn ordinary food to extraordinary.

Nowadays, the hot chili oil is sold in jars everywhere under various brands. In the States, you can find it in Asian supermarkets or specialty stores for about 3 USD per jar.

Despite the commercial availability I still insist on making my own homemade chili oil.

Because it is easy to make, it is of better taste, and most importantly it’s 100% MSG and additives free!

Plus it makes a wonderful gift for a foodie friend of yours 🙂

Important Notes on Chinese Chili Oil:

  • To get the best flavor, consider using a blend of dried chilies. In this recipe, I have combined two kinds of chili peppers (the larger ones are very fragrant and the small ones are very spicy) to get a good amount of kick and aroma.
  • I prefer to not use pre-made chili powder. For one,you don’t know how spicy the chili powder is. Also, the package powder is often stale and just can’t compare to the freshly roasted and ground chili. Get a spice or coffee grinder and work with whole chilies so you can control how spicy you want your chili oil to be.
  • Don’t go crazy with spcies. Some recipes call for a secret blend of 30+ spices in making chili oil but in my experience, anywhere from 2-5 spices are perfectly fine for an everyday use chili oil.
  • Temperature is the key. If the oil is too hot, it burns the chili powder and gives the chili oil a burnt taste. If the oil is too cold, it doesn’t fully extract the flavor out of the chili. If you use a cooking thermometer, make sure the oil is around 200c/390f.
  • If you are not sure, test out with lower temperature so at least you don’t burn the chili powder.
