Chilli Crisp

This aromatic chilli crisp is a versatile vegan condiment that adds a punch of heat and a satisfying crunch to almost any meal. By slowly infusing vegetable oil with shallots, garlic, star anise and cinnamon, you create a complex savoury base that perfectly balances the fiery kick of crushed red pepper flakes. The key is patience, allowing the aromatics to gently fry until golden and crisp, ensuring a deep flavour profile that shop-bought versions simply cannot match.

Ideal for drizzling over silken tofu, noodles or even simple steamed greens, this homemade oil is a fantastic pantry staple for anyone who enjoys bold flavours. Because it keeps well in the fridge for up to a month, it is an excellent make-ahead project for busy home cooks. Serve it as a finishing touch to stir-fries or as a dipping sauce for dumplings to elevate your everyday cooking with minimal effort.

Ingredients for Chilli Crisp

  • 4 small shallots, thinly sliced

  • 2 heads of garlic, separated into cloves, thinly sliced

  • 2 (3") cinnamon sticks

  • 6 star anise pods

  • 350ml vegetable oil

  • 1 (2") piece ginger, peeled, very finely chopped

  • 60ml crushed red pepper flakes

  • 2 tablespoons soy sauce

  • 2 teaspoons sugar

Bring shallots, garlic, cinnamon, star anise, and oil to a simmer in a medium saucepan over medium heat. Cook, reducing heat as needed to maintain a gentle simmer and swirling pan occasionally, until shallots and garlic are browned and crisp, 20–25 minutes. (Take your time—you want to drive all the moisture out of the shallots and garlic before they brown.)

Mix ginger, red pepper flakes, soy sauce, and sugar in a medium bowl to combine. Strain shallot mixture through a fine-mesh sieve into ginger mixture. Let shallots and garlic cool in sieve (this will allow them to crisp further), then stir into sauce.

Do Ahead: Chilli crisp can be made 1 month ahead. Cover and chill.
