In a large skillet or wok, heat 1 tablespoon of coconut oil over medium heat until melted and hot.
Add 2-3 tablespoons of green curry paste to the skillet. Stir for about 1-2 minutes until fragrant, making sure not to let it burn.
Add 4 diced chicken thighs to the skillet. Cook for about 5-7 minutes, stirring occasionally, until the chicken is browned and cooked through.
Pour in 14 ounces of coconut milk and stir to combine with the chicken and curry paste. Bring the mixture to a gentle simmer.
Stir in 3 teaspoons of fish sauce, 3 teaspoons of brown sugar, 1 teaspoon of lime zest, 1 tablespoon of lime juice, and 1/2 teaspoon of white pepper. Adjust the seasoning to taste.
Incorporate 1 diced zucchini and 10 green beans into the curry. Simmer for an additional 5 minutes until the vegetables are tender yet crisp.
Remove the skillet from heat and fold in 1 cup of Thai basil. The residual heat will wilt the basil, enhancing the flavor of your curry.
Serve the Thai Green Curry with Chicken over a bed of warm white rice. Enjoy!
