The History of Chilli Oil

Chilli oil has deep roots in Chinese cuisine, where it’s used to enhance a wide range of dishes, from noodle bowls to dumplings.

The technique of infusing oil with spices and heat has been around for centuries, and over time, chilli oil has evolved to include additional flavours like garlic, ginger, and Sichuan peppercorns.

This homemade chilli crisp oil takes inspiration from traditional recipes, adding crispy shallots and garlic for extra texture and depth, making it a favourite in many modern kitchens.

Instructions

This recipe makes roughly two 300ml jars, so you’ll always have some on hand to elevate your dishes and bring the magic of chilli oil into your kitchen!

1. Prepare the Aromatics and Spices

Using a mandolin or a sharp knife, thinly slice the shallots and garlic to ensure even cooking.

Set aside the dried chillies in a bowl, and have your whole spices (ginger, star anise, Sichuan peppercorns, and cinnamon stick) ready on a separate plate.

2. Fry the Shallots and Garlic

Heat your choice of cooking oil in a pot over medium heat. Add the sliced shallots and garlic, stirring occasionally.

Fry patiently until they turn golden brown - this takes time, so avoid rushing it!

Once browned, use a slotted spoon to transfer the aromatics to kitchen towel, letting them crisp up and drain. Reserve the infused oil for later.

3. Infuse the Oil with Whole Spices

Pour the reserved oil back into the pot, then add the whole spices (ginger, star anise, Sichuan peppercorns, and cinnamon stick).

Let them sizzle for 3-4 minutes to release their fragrance.

4. Prepare the Chilli Mixture

In a separate bowl, combine the dried chillies, sugar, salt, MSG (optional), Chinese black vinegar (optional), and toasted peanuts and sesame seeds (if using). Mix everything well.

5. Combine the Infused Oil and Chilli Mixture

Turn off the heat under the infused oil and let it cool slightly for about 2 minutes. The ideal temperature is around 180ºC/360ºF (use a meat thermometer if you have one).

Carefully pour the hot oil over the chilli mixture - you’ll hear it sizzle! Stir thoroughly to combine.

6. Let the Flavours Develop

For the best flavour, let your chilli crisp rest for at least 24 hours before using. Store it in airtight jars and be sure to stir before each use to keep the flavours evenly distributed.

FAQs

How much chilli oil should I use each time?

A little goes a long way. Start with a small amount and adjust to your spice tolerance. This condiment adds a fiery kick to countless dishes –  noodles, dumplings, soups, and more! So get creative and explore the endless possibilities.

What's the difference between crispy chilli oil and regular chilli oil?

Regular chilli oil is made by infusing oil with dried chillies. Crispy chilli oil takes it a step further by adding crispy shallots, garlic, and sometimes nuts and seeds for an extra layer of texture and flavour.

How spicy is this chilli oil?

The spice level depends on the type of chillies you use. This recipe uses a combination of dried chillies, some with more heat than others. You can adjust the spice level by using fewer or milder chilli flakes, or by removing the seeds from the dried chillies before using them.

What can I use this chilli oil for?

Crispy chilli oil is a versatile condiment that can be used on a variety of dishes. Here are a few ideas:

  • Noodles and dumplings: Drizzle some over your favourite noodle dish or dumplings for a spicy kick.
  • Soups and stews: Add a spoonful to soups or stews for an extra depth of flavour.
  • Salads: Use a small amount to add a spicy touch to your salad dressing.
  • Eggs: Drizzle some over fried eggs or scrambled eggs for a delicious flavour boost.
  • Stir-fries: Add a spoonful to your stir-fry for a spicy and flavourful sauce.

How long does this chilli oil last?

Stored in an airtight container in the fridge, your crispy chilli oil should last for several months. The flavours will actually continue to develop and deepen over time.

Can I substitute any ingredients?

  • Sunflower oil: You can substitute another high smoke point oil, such as peanut oil or vegetable oil.
  • Dried chillies: You can experiment with different types of dried chillies to find your preferred heat level and flavour profile.
  • Optional additions: Feel free to leave out the peanuts and sesame seeds, or substitute with other nuts or seeds, such as cashews or pumpkin seeds.

I don't have a mandolin, can I still make this?

Yes, you can! Just use a sharp knife to thinly slice the shallots and garlic as best you can. Aim for uniform thickness for even cooking.

My chilli oil turned out burnt, what went wrong?

Be patient when frying the shallots and garlic. They will eventually brown, but they can burn quickly once they start to colour. Keep a close eye on them and adjust the heat if necessary.
