Essential Ingredients for Homemade Chilli Oil Recipe

To make a rich and balanced DIY Chilli Oil, gather the following:

• 1½ cups neutral oil (grapeseed, canola, or peanut oil)
• ½ cup dried chili flakes (adjust for spice level)
• 1 tbsp Sichuan peppercorns (optional, for numbing heat)
• 4–5 cloves garlic, minced or sliced
• 1 tbsp ginger, finely minced
• 1 tsp salt
• 1 tsp sugar
• 2–3 star anise pods
• 1 cinnamon stick
• 2 bay leaves

Optional add-ins:

• 1 tbsp sesame seeds
• 2 tbsp soy sauce (for extra umami)
• 1–2 tbsp fermented chili paste for deeper flavor

Choosing the Right Chilies for Heat & Flavor

The type of chili you use shapes the flavor of your hot oil recipe.

• Mild heat: Kashmiri red chilies or Aleppo pepper flakes for vibrant color without overwhelming spice.
• Medium heat: Thai bird’s eye chili flakes for a noticeable kick.
• High heat: Chinese facing heaven chilies or extra-hot crushed red pepper.

For Chinese Chili Oil, traditional Sichuan dried red chilies give that signature deep red color and complex flavor.

Kitchen Tools You’ll Need for DIY Chilli Oil

• Small saucepan or wok
• Heatproof glass jar with lid (sterilized)
• Fine mesh strainer or slotted spoon
• Measuring cups and spoons
• Heatproof spatula

If you plan to preserve your oil, you’ll also need canning jars and lids for proper storage.

Step-by-Step Instructions for the Perfect Hot Oil Recipe

Step 1 – Prepare the jar:
Sterilize your jar and lid by boiling them in water for 10 minutes. This is crucial for Ajika preservation.

Step 2 – Heat the oil:
In a saucepan, combine the oil, star anise, cinnamon, and bay leaves. Heat on medium until small bubbles form—around 225°F (110°C).

Step 3 – Add aromatics:
Add garlic and ginger, stirring occasionally until they turn light golden and fragrant. Do not burn them.

Step 4 – Remove solids:
Using a slotted spoon, remove the whole spices, garlic, and ginger to prevent bitterness.

Step 5 – Infuse with chili:
Place your chili flakes, salt, sugar, and optional Sichuan peppercorns into the heatproof jar. Carefully pour the hot oil over them. Stir gently to release flavor and color.

Step 6 – Cool and store:
Let cool completely before sealing. Store in a cool, dark place.
