Chili oil is one of the simplest condiments you can make, and one of the most useful to keep within reach. It’s created by pouring hot oil over dried chili flakes, allowing the heat to unlock their flavor, aroma, and color. The result is an oil that carries warmth without harshness and depth without effort.
This is a foundational recipe. A spoonful can sharpen noodles, anchor a dipping sauce, or finish a dish that feels like it’s missing something, but you can’t quite name why. It takes minutes to make, then time does the rest.

Ingredient List
Dried Chili Flakes: Standard crushed red pepper flakes work perfectly. They create a balanced chili oil with moderate heat and familiar flavor. Chinese or Sichuan chili flakes can be used for deeper color and more fragrance.
Peanut Oil: Peanut oil is traditional because of its high smoke point. Unrefined peanut oil has a noticeable peanut aroma and flavor, which creates a richer, nuttier chili oil. This is normal and works especially well with noodles and dipping sauces. For a more neutral flavor, use refined peanut oil or another neutral oil such as avocado oil or grapeseed oil.
How to Make Chili Oil
- Place the dried chili flakes into a clean, completely dry, heatproof glass jar.
- Heat the peanut oil in a small saucepan over medium-high heat until it reaches about 400°F and just begins to smoke lightly.
- Remove the oil from the heat and let it cool for 5–7 minutes, until it reaches approximately 325–350°F.
- Test the oil by dropping in a single chili flake. It should gently sizzle, not aggressively bubble.
- Slowly pour the hot oil over the chili flakes. The flakes will sizzle briefly as the oil extracts their flavor.
- Let the chili oil cool completely, uncovered.
- Seal the jar with a lid and allow the oil to mature for 5–7 days before using for best flavor.
Expert Tips
Temperature control determines flavor. Oil that is too hot scorches the chili flakes and creates bitterness. Oil that is too cool will not fully extract their flavor.
The flavor improves significantly over the first week. Fresh chili oil tastes sharp and simple; time allows the flavors to deepen and integrate.
Always use a completely dry jar. Any water introduced into the oil can shorten shelf life.
Sediment at the bottom is normal. The chili flakes continue infusing the oil over time.
Store in a sealed jar in a cool, dark place for up to 6 months. Always use a clean spoon when serving.
Serving Suggestions
- Spoon over fried or soft scrambled eggs
- Drizzle over noodles or rice
- Add to dumpling dipping sauces
- Finish roasted vegetables such as broccoli or Romanesco
- Stir into mayonnaise for a quick spicy aioli
- Add to brothy soups just before serving
FAQs
Oil that is too hot burns the chili flakes, which creates bitterness instead of clean, balanced heat.
Flavor compounds continue dissolving into the oil over time, creating a deeper, more integrated flavor.
No. Fresh chilies contain water, which prevents proper infusion and can cause spoilage.
This usually means the oil was too hot and scorched the chili flakes.
No. Store it in a cool, dark place at room temperature.
It likely needs more time to mature, or the oil was not hot enough during preparation.
