Sauté the ingredients: Wash the green beans and remove the stems. Slice the onions and garlic, then rinse and cube the chicken. Sauté the chicken in cooking oil for 6 minutes until caramelized. Add Thai red curry paste, onions, and garlic, mixing well to release the oils. Pour in half of the coconut cream and simmer for 2 minutes on high heat.
Add the protein: Add chicken, 1/2 cup of water, the remaining coconut cream, lime juice, kefir lime leaves, and lemongrass. Stir in green beans and red chili. Reduce the heat to medium-low and simmer for 20 minutes with the lid on, ensuring the chicken cooks through while the vegetables remain crisp.
Serve: Remove the kefir lime leaves before serving. Enjoy with Thai jasmine rice, garnished with lime slices for added flavour.
