Begin by preparing the chicken thighs. Pat them dry with a paper towel and season with salt and pepper. Place them at the bottom of the crockpot.
In a mixing bowl, combine the coconut milk, chicken broth, red curry paste, grated ginger, minced garlic, soy sauce, and turmeric. Whisk until all ingredients are blended well.
Pour the coconut curry mixture over the chicken in the crockpot.
Add the sliced red bell pepper, green beans, and onion on top of the chicken. Stir gently to combine everything, ensuring the vegetables are also coated in the curry sauce.
Cover the crockpot and cook on low for 6-8 hours or on high for 3-4 hours, until the chicken is tender and cooked through.
Once cooked, shred the chicken in the pot using two forks, then mix everything well to combine the flavors. Taste and adjust seasoning as necessary.
Serve hot over rice or quinoa, garnished with fresh cilantro and a squeeze of lime juice.
