Chilli Oil

Introduction

Chilli oil is a pantry staple that takes five minutes to make and transforms any savory dish—noodles, soups, roasted vegetables, eggs, or grains. The technique of tempering the chile flakes with a small amount of oil before the hot pour prevents them from burning, which keeps the heat clean and the flavor bright rather than acrid.

Recipe Details

• Prep Time: 5 minutes
• Cook Time: 5 minutes
• Total Time: 10 minutes
• Servings: About ½ cup

Ingredients

• 50 grams chile flakes
• ½ teaspoon salt
• ½ cup peanut oil

Instructions

1. Mix chile flakes and salt in a heat-proof bowl.
2. Mix 1 tablespoon of the oil into the chile flake/salt mixture. This will prevent the chile from scorching when hot oil is added later.
3. Heat peanut oil to about 200°C (392°F). Small bubbles should form when poking a wooden chopstick into the oil.
4. Pour heated oil over chilli flake mixture and stir vigorously.
5. Allow to cool and store in a container.

Variations

Use different chile flakes. Swap the standard red chile flakes for Aleppo pepper, urfa biber, or a blend of milder varieties to lower the heat and shift the flavor profile toward fruity or smoky notes.

Add aromatics. Stir in minced garlic, sliced shallots, or whole cumin seeds into the chile flake mixture before the oil pour for a more complex, savory depth.

Infuse with herbs. Once the oil has cooled slightly, add fresh thyme, oregano, or rosemary sprigs to steep as it cools completely for an herbal undertone.

Brown your oil first. Heat the peanut oil until it begins to brown slightly before pouring it over the mixture to add a toasted, nutty dimension.

Make it garlic-forward. Add 4–5 minced garlic cloves to the bowl with the chile flakes and salt, then proceed as usual for a chile oil that leans savory and umami-rich.

Tips for Success

Use a heat-proof bowl. Glass or ceramic withstands the thermal shock of 200°C oil better than plastic. Avoid metal bowls, which conduct heat too aggressively and can cause the mixture to scorch at the bottom.

Temper the flakes with a tablespoon of oil first. This step is not optional—it coats the chile flakes and prevents them from scorching when the main volume of hot oil hits. Without it, you’ll end up with bitter, burnt-tasting oil.

Test the oil temperature with a wooden chopstick, not your finger. When you see small, consistent bubbles rising from the tip of the chopstick submerged in the oil, you’ve reached roughly 200°C. If the oil smokes heavily, it’s too hot; let it cool for 30 seconds and try again.

Stir vigorously after the pour. This distributes the heat evenly through the chile flakes and prevents them from clumping as the oil cools. Don’t walk away—a few seconds of stirring makes a visible difference.

Let it cool completely before storing. Chilli oil continues to infuse as it cools, and any residual heat can cause condensation inside the container, which will introduce water and shorten shelf life.

Storage and Reheating

Store chilli oil in a clean glass jar with a tight-fitting lid at room temperature, away from direct sunlight. It keeps for up to 2 months without refrigeration due to the oil’s preservative properties. If you notice any off smells or cloudiness, discard it.

FAQ

Can I use vegetable or canola oil instead of peanut oil?

Yes. Peanut oil has a slightly higher smoke point and neutral flavor, but vegetable, canola, or sunflower oil work just as well. Avoid olive oil, which has a lower smoke point and will break down at 200°C.

Why does my chilli oil taste bitter?

The chile flakes likely scorched during heating. This happens if you skip the initial tablespoon of oil tempering or if the oil exceeds 200°C. Start again with fresh flakes and monitor the oil temperature carefully with a chopstick test.

How hot will the finished chilli oil be?

Heat level depends entirely on the chile flakes you choose. Standard red chile flakes are moderately spicy; milder varieties like Aleppo pepper or Marash will yield a gentler oil. Taste a small amount on a spoon before using it generously on food.

Can I make this in large batches and store it?

Yes. The recipe scales easily—multiply the ingredients proportionally and use the same 200°C temperature. Store in glass jars with tight lids at room temperature for up to 2 months.
