Step 1

Heat the oil in a wok or large, deep frying pan until hot and just smoking. Add the steak, together with a pinch of both salt and pepper. Let this fry over a high heat for 2-3 minutes until charred. Remove from the pan and set aside.

Step 2

In the same pan, add the shallot and fry for 30 seconds before adding the curry paste - stir about 30 seconds before adding the beans, kaffir lime leaves and Thai chillies (if using). Splash in around 1 cup of water too.

Step 3

Stir everything and let the beans simmer in the pan for 3 minutes until just cooked through. The sauce should also have reduced a little.

Step 4

Return the beef to the pan with any juices along with the fish sauce and sugar. Stir fry for 30 seconds then remove from the heat, and you’re done!

Step 5

Serve with fluffy jasmine rice.
