Set your pressure cooker to the sauté function. Heat some oil, then add the chopped onion and cook until it begins to soften.
Add the chicken and cook until sealed.
Add the red curry paste, and stir until softened and the chicken is coated. If there is anything stuck to the base of the pot, pour a little of the hot stock in and use a wooden or silicone spatula to scrape it off. It's important that nothing is stuck to the base of the pot when you set off the pressure cooker.
Switch off the sear function.
Add the garlic, ginger, coconut milk, fish sauce, sugar, coconut milk, stock, vegetables and lime juice. If you have some, add the lemongrass at this point too.
Mix well to combine.
Secure the lid and set your pressure cooker to high pressure for 6 minutes.
Once the cooking cycle is complete, carefully perform a quick pressure release following your pressure cooker’s instructions.
Remove the lid and check the consistency. If it is too thin switch on the sear function and leave it to simmer for about 5 to 10 minutes or until it is at your desired thickness.
Ladle the curry over white rice (jasmine works well). Garnish with fresh coriander and an optional extra squeeze of lime for that zesty finish.
Notes
Note 1: I used 3 tablespoons of Mae Ploy Thai red curry paste (I bought it on Amazon) which created a hot flavour. The spice level will very much depend on the type of Thai red curry paste you use.Note 2: For simplicity I often use pre chopped frozen garlic and ginger.Note 3: You can substitute with your favourite vegetables, you could use aubergine, courgette, green beans etc.
