Crispy Chilli Oil: The Complete Guide

What is crispy chilli oil?

At its simplest: chilli and aromatics fried in oil, jarred with the solids left in.

The category has been around in Chinese home kitchens for a very long time, with households and restaurants each making their own version. What changed everything was 1997, when a restaurateur in Guizhou called Tao Huabi started producing hers commercially under the name Lao Gan Ma, or Old Godmother. She had been running a noodle shop where customers kept turning up for the sauce rather than the noodles. That was the first time chilli crisp was made and sold at commercial scale, and it went on to become a pantry staple across China and then, slowly, everywhere else.

Now there are dozens of brands, three or four regional traditions, and a lot of confusion about what to call the stuff. Let us sort that out first.

Chilli crisp vs chilli oil: what is the difference?

Short answer: chilli oil is strained, chilli crisp is not.

Plain chilli oil is made by pouring hot oil over chilli flakes, letting the flavour and colour bleed out, then straining. What you keep is the oil. It is fragrant and clean and it is what most restaurants brush over dumplings or stir into dressings.

Chilli crisp, also called crispy chilli oil or chilli crunch, keeps everything. The fried chilli, the roasted garlic, the sesame, sometimes fermented soybean or shallots. The oil becomes a delivery vehicle for the solids rather than the point of the exercise.

In practice the labels are used loosely and plenty of products sit somewhere in between. The reliable test is to look at the jar. If you can see a thick layer of solids at the bottom and only a couple of centimetres of clear oil on top, it is a crisp. If it is mostly red liquid, it is an oil.

What about chilli crunch, la you and rayu?

• Chilli crunch is essentially a marketing name for the same thing, popularised by Western brands.
• La you (辣油) or hong you (红油) is the Chinese term for chilli oil, usually the strained Sichuan style.
• Rayu is the Japanese version, generally lighter and more sesame-forward. The chunky style is called taberu rayu, literally "chilli oil you eat", which is a very good description of the whole category.
• Chili oil, chile oil, chilli oil. Same product, different spelling conventions. American brands use one L, British and European brands generally use two.

What is actually in the jar

Most crispy chilli oils are built from four groups of ingredients.

• The oil. Usually a neutral one: sunflower, rapeseed, soybean or, at the cheaper end, palm oil. This makes up the bulk of the product and it matters more than people think, because it carries every other flavour.
• The chilli. Flakes or coarsely ground dried chilli. The percentage is the single most useful number on the label. Ours is 18%, which is high for the category.
• The aromatics. Garlic and shallot are the most common, sometimes ginger, sometimes fried onion. This is where crunch and savoury depth come from.
• The seasoning. Salt, sugar, soy sauce, sesame seeds, Sichuan peppercorn, fermented soybean, spice blends. Some brands also use MSG or yeast extract for a savoury shortcut.

For reference, ours is sunflower oil, chilli (18%), garlic, gluten-free soy sauce, brown sugar, sesame seeds, Sichuan peppercorn, spices and natural vegetable stock. Nine things, no MSG, no artificial flavourings, no preservatives. The oil itself acts as the preservative, which is how a jar keeps for up to a year.

How crispy chilli oil is made

The process sounds simple and is not. Broadly:

1. The aromatics get fried slowly in oil until golden and dehydrated. Slowly is the operative word, because the goal is to drive out moisture, not to brown the outside.
2. The oil is brought to temperature and poured over, or cooked with, the dried chilli. Too hot and the chilli scorches and turns bitter. Too cool and you get raw, dusty flavour and no colour.
3. Seasonings go in, the batch cools, and it is jarred with the solids suspended in the oil.

The hard part is crunch that lasts. Anything with moisture left in it will go soft in the jar within weeks, which is why a lot of chilli oils are crunchy on day one and disappointing by the time you are halfway down. Getting garlic to stay crisp for twelve months while sitting in oil is a matter of frying temperature, timing and ratio, and it is the bit that separates a good jar from a cheap one.

The regional styles worth knowing

• Sichuan. Fragrant and numbing, built on Sichuan peppercorn for that tingling málà effect, often with star anise, cassia and bay in the oil. Typically the strained style.
• Guizhou. The Lao Gan Ma template. Fermented soybean and preserved vegetable give it a deep, funky, savoury character. Heavier on the solids.
• Taiwanese. Where ours comes from. Garlic-forward and roasted rather than fermented, with sesame and a lighter touch of peppercorn. Aromatic rather than aggressive.
• Japanese. Rayu is lighter and more sesame-driven. The chunky taberu rayu style took off after 2009 and is milder and sweeter than most Chinese versions.
• Western premium. A newer wave of small brands using shallots, mushroom powder, coconut, tamarind and anything else that works. Wildly varied, sometimes excellent, usually expensive.

How to choose a good crispy chilli oil

Six things to check, roughly in order of usefulness.

1. The solids to oil ratio. Hold the jar up. You want a deep layer of solids. A thin sludge under a lot of oil means you are paying for sunflower oil at condiment prices.
2. The chilli percentage. Not every brand declares it. The ones that do are usually the ones with something to declare.
3. Which oil. Palm oil is cheap and appears in a lot of budget jars. Sunflower and rapeseed are neutral and let the aromatics through.
4. MSG, yeast extract and flavourings. Not dangerous, but they are doing the job that real garlic and real spice should be doing. If a label leans on them, the actual ingredient quality is usually lower.
5. Heat level. Look for a stated rating. "Hot" on the front of a jar is meaningless on its own. Most people want medium, which is around a 3 out of 5.
6. Where it was made and how long ago. Fried aromatics soften with age. Small-batch production and a shorter supply chain generally means a crunchier jar.

If you want a straight comparison against the big names, we put ours side by side with Lao Gan Ma and others in our guide to the best crispy chilli oils. It is honest about where the cheaper jars win.

20 ways to use crispy chilli oil

The category rule: crispy chilli oil loves fat, starch and blandness. Anything creamy, anything carby, anything that needs waking up.

Everyday

1. Fried eggs. The gateway. Crispy edges, runny yolk, a spoonful over the top.
2. Noodles. Whisked with soy, black vinegar and noodle water it becomes a full sauce in ninety seconds. Full method in our 10-minute chilli oil noodles.
3. Instant ramen. Bin half the flavour sachet, add a spoon of this instead.
4. Rice. Plain rice, chilli oil, a fried egg. Dinner.
5. Avocado toast. Yes it is a cliché. It is also correct.
6. Dumplings and gyoza. Mixed with a little soy and rice vinegar as a dipping sauce.

Cooking

7. Roasted vegetables. Sprouts, cauliflower, broccoli, carrots. Toss after roasting, not before.
8. Stir-fries. Off the heat at the end, so the crunch survives.
9. Soups and ramen broth. A spoon on top adds fat, colour and heat all at once.
10. Roast potatoes and fries. Straight from the oven while they are still shining.
11. Grilled or roast chicken. Spoon over at the table.
12. Tofu. Crispy tofu is a blank canvas that badly needs this.

Less obvious, all good

13. Pizza. Especially margherita. Then try it alongside hot honey and thank us.
14. Cheese toasties and grilled cheese. Inside, not on top.
15. Hummus and dips. Pooled in the middle with a swirl of olive oil.
16. Burrata and mozzarella. Sharp, rich, crunchy.
17. Mayonnaise. Stir it in for an instant spicy mayo for burgers and sandwiches.
18. Salad dressing. With rice vinegar, soy and a little sugar.
19. Popcorn. Melted butter first, then chilli oil, then salt.
20. Vanilla ice cream. Sounds unhinged, tastes like salted caramel's spicier cousin.

Finishing versus cooking

Treat it as a finishing condiment. If you fry with it, two things happen: the crunchy solids soften and go soggy, and the fried aromatics can catch and turn bitter at high heat. You also lose the aroma, which is half of what you paid for. Add it at the end, off the heat, or at the table.

How to store crispy chilli oil

Cupboard or fridge, both fine. The oil acts as a natural preservative, and a sealed jar keeps for up to twelve months in cool, dry storage. The fridge slows down the oxidation that eventually dulls the flavour, so if you are a slow user it is the safer bet. Cold oil thickens and can look cloudy, which is normal and reverses at room temperature.

Three habits that matter more than where you keep it:

• Clean, dry spoon, every time. Water and food debris are what actually spoil a jar.
• Keep the solids submerged. Level the surface after each use so nothing is left sitting dry above the oil line.
• Stir before serving. The good bits sink. Most people who say a chilli oil "tastes of nothing" have been pouring off the top layer.

Should you make your own?

Try it once, absolutely. It is fun and and it teaches you what each element does. Toast your aromatics low and slow, heat neutral oil to around 120°C to 140°C for garlic and shallot, then pour hotter oil over the chilli flakes and watch it bloom.

Two things to look out for: The first is crunch. Homemade batches almost always go soft within a week or two, because getting moisture out of fresh aromatics without burning them is harder than it looks.

How hot is crispy chilli oil?

It varies enormously, from barely warm to genuinely painful. Most mainstream jars land in the medium range, because the point of the category is flavour rather than endurance.

Ours is a 3 out of 5. Garlicky and savoury first, warmth after, the kind of heat that makes you want another bite rather than a glass of milk. If you want less, use less. Unlike a hot sauce, the dosage is entirely in your hands because you are spooning it, not shaking it.

Crispy chilli oil FAQs

What is the difference between chilli crisp and chilli oil?

Chilli oil is strained, so you keep only the infused oil. Chilli crisp, also called crispy chilli oil, keeps the fried chilli, garlic and other solids in the jar. Chilli oil gives you heat and aroma, chilli crisp adds texture and savoury depth.

Is crispy chilli oil vegan?

Usually, but not always. Some traditional versions include dried shrimp or other seafood, and some XO-style products are not plant-based. Chilli Chan's Crispy Chilli Oil is vegan and gluten-free, using gluten-free soy sauce and a natural vegetable stock.

Does crispy chilli oil need to be refrigerated?

No. A sealed jar keeps for up to a year in cool, dry storage because the oil acts as a natural preservative. The fridge slows oxidation and keeps the flavour brighter for longer, so it is a good option if you use it slowly. Cold oil thickens, which is normal.

Can you cook with crispy chilli oil?

You can, but it works far better as a finishing condiment. High heat softens the crunchy solids and can turn the fried aromatics bitter. Add it off the heat at the end, or at the table.

How long does crispy chilli oil last once opened?

Up to twelve months if you keep it sealed, always use a clean dry spoon, and keep the solids under the oil line. Check the best before date on your jar.

Is crispy chilli oil the same as sriracha or sambal?

No. Sriracha and sambal are wet, blended chilli pastes or sauces, usually with vinegar and a smooth or coarse texture. Crispy chilli oil is oil-based with dry fried solids in it, so it adds richness and crunch rather than tang.

Why has my chilli oil gone bitter?

Almost always burnt chilli or burnt garlic, from oil that was too hot during production or from frying with it at high heat at home. Scorched chilli is bitter and there is no fixing it after the fact.
