A step by step recipe guiding you to make Chinese spring onion oil (aka scallion oil) without fail. You will also learn how to use this versatile condiment in six ways.
In a typical Chinese kitchen, you can always find three indispensable herbs: spring onion (aka scallion or green onion), ginger and garlic. They are common ingredients yet give dishes so much aroma and flavour. Unlike ginger and garlic which can be kept at room temperature for quite a while, spring onion doesn’t last that long, even when kept in the fridge. That’s why a jar of homemade Chinese spring onion oil (葱油, aka scallion oil) comes in handy.
3 tips to ensure the desired result
The making of Chinese spring onion oil is pretty straightforward: just simmer spring onion in oil over medium-low heat, then cool and store. The traditional recipe usually calls for spring onion only. I like adding one more ingredient to the recipe: shallot or onion. This will enhance the fragrance and flavour of the finished oil. A few tips for helping you achieve the desired result:
- The lower the heat is, the longer will it take you to simmer. However, an extended process will extract more flavour from the shallot and spring onion, thus the oil will be more aromatic.
- It takes me 25 minutes or so to complete the simmering over medium-low heat. Do keep a close eye on it as you don’t want to over-fry the ingredients which might leave an unpleasant burnt flavour in the oil.
- To make this recipe even simpler, you may skip shallot/onion and only use spring onion. If you don’t wish to store up a big batch, please feel free to cook a small amount as required.
6 ways to use spring onion oil
Chinese spring onion oil can be used in many ways. It’s truly worth having it in your kitchen. Not only does it provide a unique aroma to dishes, but it will also save you lots of time in everyday meal preparation.

How to make & use spring onion oil (葱油)
Ingredients
- 480 ml cooking oil (sunflower/rapeseed/vegetable, etc.) - 2 cups
- 150 g shallot or onion - 5.3oz
- 150 g spring onion - 5.3oz, about 15 stalks
Instructions
- Peel shallot then thinly slice. Wash spring onion then dry thoroughly with kitchen towel/paper. Cut into long sections (separate the white part and the green part).
- Pour oil into a wok (or a deep frying pan). Heat over medium-low heat. Add shallots then leave to simmer until it becomes lightly brown. Turn off the heat (see note 1 & 2). Take out the shallot pieces with chopsticks.
- Turn the heat back on. Add the white part of the spring onion. Leave to simmer over medium-low heat until it wrinkles a bit. Add the green part of the spring onion. Turn off the heat when it turns brown (see note 1 & 2).
- Pour the oil into a sterilized, airtight jar. Store in the fridge and use it within a month. Use a clean spoon each time you use the oil.
A SIMPLE & FAST VERSION:
- You may use only spring onion and cook on a slightly higher heat thus the simmering time will be shorter. Make sure to observe closely during the process to avoid burning.

Can I leave the shallots and onions in the oil when refrigerated?
I wouldn’t leave them in the oil for too long. Use them as toppings for noodle or rice dishes after you make the oil.
1. If you leave the onions and shallots in the oil the whole time, how long will it store in the fridge?
I think you could keep them in the oil for 3-4 days.
I wanted to make this last night but it didn’t happen. Made it this morning while my daughter made pancakes. I first used it in a bacon vinaigrette dressing, which tasted amazing!
Tonight before we get on the road, I’m going to try making some pasta with it.
Yes Melanie, it can be used in so many dishes and it makes ordinary food shine!
I made your Chinese chili oil yesterday and poured it into a jar this morning. Today when I get home I’m going to add this to my growing flavored olive oils!!! I’ve got garlic, and an Italian (rosemary, sage, thyme), and this one sounds delightful! Used the chili oil late last night for dumpling sauce and it was amazing!!!
Chili oil and spring onion oil are extremely versatile, right?
Hi Wei! I periodically I receive your recipes in my mail and there are none that I have not wanted to make, they are all a work of art, you cook fantastically well. I hope one day we can receive our friends at home and be able to delight them by replicating your recipes. In Spain, Asian food is known for the restaurants that have made everything Spanish way, puff !. Sometimes we order food from the restaurant but we know that it is not what eat in China. Well, I am in the slow cooker phase, they have fascinated me 1. because they are cheap, it’s almost no spend electricity 2. you put the ingredients and you don’t worry until it finish 3. I put them to work at night away from home, I never have smell food , YUPPI! and etc etc etc. Question; could I make this oil in that? example putting everything and cooking 5 hours on low, it would bring out all the flavors, without boiling. How about?. Take care of yourself precious and thank you in advance. I’m Spanish, Latina, sorry for talking so much ja ja ja 😘😘😘
I haven’t used a slow cooker so I’m not 100 % sure. But I’ve done some research online. It seems a great idea to make infused oil this way. You can find some general instructions through Google (search “infused oil in slow cooker”). Happy cooking and let me know how it turns out!
Of course my dear ,I Will inform you

Hi, I’m curious… can you leave the onions and shallots in the oil the whole time, or do you need to take them out before storing the oil in the fridge? Also, I have an empty jar with a lid, if it’s clean, will that work?
Hi Julian! I wouldn’t leave the onions and shallots in the oil for too long. Yes, you can use a regular jar with a lid.
I don’t understand if I did it correctly, were they actually supposed to turnn brown or do you mean dark muddy green? I’m not sure if I simmered them long enough.
When the green part of the spring onion turns lightly brown, it should be done. As I mentioned in the recipe, it took me about 15 minutes to simmer the shallot then about 10 minutes for the spring onion.
Hi,
Just wondering if canning is an alternative way instead of placing it inn the fridge. Thanks
Hi Vans! I assume it’s ok but I’m not 100% sure as I’m not familiar with canning fat/oil. Maybe you can search more information online about home canning.
Hi – Just found this recipe and discovered your blog and love it! Looking forward to trying this recipe out, and many others.
Thanks Tina! I’ve been following you on IG. Love your breakfast creations!
