Chili Garlic Oil Recipe (Homemade, Ready in 15 Minutes)

There is a jar in my fridge that gets opened more than almost anything else in the kitchen. It is chili garlic oil, and once you have a spoonful on hand, you will understand why. A little heat, a little crunch, a lot of garlic, and suddenly plain noodles taste like a restaurant made them.

This is not a sauce you buy and forget about. It takes fifteen minutes, one small saucepan, and ingredients you probably already have. Hot oil does all the work, blooming the chili flakes and toasting the garlic until the kitchen smells amazing.

The trick is temperature. Heat the oil just hot enough to sizzle the flakes without scorching them, and the garlic stays golden instead of bitter. Get that right and the oil turns a deep red, with a flavor that is warm rather than punishing.

I keep a jar of this chili garlic oil recipe on standby for nights when dinner needs rescuing. Eggs, rice, dumplings, noodles, even pizza, all get better with a spoonful drizzled over the top.

Why You’ll Love This Recipe

The flavor is layered, not just hot. Chili flakes bring warmth, garlic brings savory depth, sesame seeds add nuttiness, and a pinch of salt ties it together. It is heat that builds slowly and fades, leaving you reaching for another spoonful.

It is also endlessly useful. One jar covers a month of meals and works on almost anything savory.

And it is genuinely easy. There is no chopping beyond mincing garlic, no special equipment, and no simmering for hours. If you can heat oil in a pan, you can make this. The hardest part is waiting for it to cool before tasting.

It is worth knowing how this differs from a bottled hot sauce. A hot sauce is blended, usually with vinegar, while this is an infusion: hot oil draws flavor out of the chili and garlic. If you like both, our homemade hot sauce is the blended, vinegary counterpart.

Ingredients

Makes about 1 cup:

• 1 cup neutral oil, such as vegetable, sunflower, or peanut oil
• ⅓ cup chili flakes (gochugaru or crushed red pepper flakes)
• 6 cloves garlic, finely minced
• 2 tablespoons sesame seeds
• 1 teaspoon kosher salt
• 1 teaspoon sugar (optional, rounds out the heat)
• 1 teaspoon Sichuan peppercorns, lightly crushed (optional)
• 1 star anise (optional)

How to Make It

1. Combine the dry ingredients: Add the chili flakes, garlic, sesame seeds, salt, sugar, Sichuan peppercorns and star anise to a heatproof bowl or clean glass jar. Keep everything dry, since water shortens the life of the oil.
2. Heat the oil: Pour the oil into a small saucepan over medium heat and warm it to about 350°F, hot but not smoking. Test it with a chili flake: it should sizzle at once. If the oil smokes, take it off the heat for a minute.
3. Pour the oil over the mixture: Carefully pour the hot oil over the chili and garlic. It will bubble and sizzle loudly, which is exactly what you want. Stir gently so every flake meets the heat.
4. Watch the garlic: The residual heat toasts the garlic as the oil cools. It should turn light golden. If it darkens fast, stir and set the bowl on a cool surface, since dark brown garlic turns bitter.
5. Let it cool: Leave the oil to cool completely at room temperature, about 30 minutes. The flavors keep developing as it sits, and the color deepens to a rich red.
6. Remove the star anise: Fish out the star anise before storing if you want a cleaner flavor, or leave it in for a stronger, more aromatic oil.
7. Jar it up: Transfer the oil and flakes to a clean jar with a tight lid. Do not strain out the crunchy bits at the bottom. That spoonful is the best part.

Cooking Tips / Variations

Temperature is the whole recipe, so do not rush it. Oil that is too cool will not bloom the chili, and the flavor stays flat. Oil that is too hot burns the garlic in seconds and the batch tastes bitter. Aim for 350°F, and when in doubt, err cooler.

Mince the garlic evenly and by hand if you can. Uneven pieces cook unevenly, and the small bits burn while the big ones stay raw. Jarred minced garlic is not a good swap here, since it holds moisture and can make the oil spoil faster.

For a milder oil, use half the chili flakes and a little extra sugar. For real fire, add another tablespoon of flakes. A teaspoon of smoked paprika adds a different kind of warmth, and crisp fried shallots stirred in at the end give you a proper chili crisp.

Serving or Storage Tips

Use this oil anywhere you want heat with flavor. Stir it through plain noodles, spoon it over dumplings, drizzle it on fried or scrambled eggs, or swirl it into rice. It also perks up roast vegetables and a plain slice of pizza.

It is especially good spooned over a bowl of tteokbokki, where the oil adds crunch and extra heat to the chewy rice cakes and glossy sauce.

Store the jar in the fridge, where it keeps for about 1 month. The oil may cloud slightly when cold, so let it sit at room temperature for 10 minutes before using. Always use a clean, dry spoon, and if it ever smells off, make a fresh batch.

Conclusion

One pan, fifteen minutes, and a handful of pantry staples are all it takes to make a chili garlic oil that beats anything in a store jar.

Heat the oil right, keep the garlic golden, and enjoy the best spoonful in your fridge.

5. Cool completely at room temperature, about 30 minutes.
6. Remove the star anise if desired.

Notes

Do not let the oil smoke; overheated oil burns the garlic and makes the batch bitter. Mince the garlic evenly so it toasts at the same rate. For milder oil, halve the chili flakes; for hotter, add another tablespoon. Variation: add smoked paprika or crisp fried shallots for a chili crisp style. Keeps about 1 month refrigerated in a clean jar; use a dry spoon every time.
