As a seasoned home cook who's mastered countless Thai-inspired dishes, I can attest that the slow cooker is perfect for this flavorful Thai chicken curry. It's hands-off, infusing every bite with rich aromas. I've perfected it both in the slow cooker and wok—both yield delicious results. Instructions for each method follow below.

Slow Cooker Thai Chicken Curry

Prep takes just 15 minutes, followed by 6 hours on low or 4 hours on high in the slow cooker. An Instant Pot works great too.

This curry features fresh vegetables, homemade Thai curry paste, and a marinade for juicy chicken.

Pro Tip: Marinate the chicken overnight for maximum flavor absorption.

Ingredients for the Vegetable and Chicken Base (Serves 4)

  • 1 can (400g) coconut milk
  • 2 onions
  • 300-400g green beans
  • 1 zucchini
  • 3 carrots
  • 4 spring onions
  • 1 red bell pepper
  • 5 sprigs fresh coriander
  • 2 chicken breasts (or cubes)

Chop the onion, zucchini, carrots, spring onions, and bell pepper into bite-sized pieces.

Variation: Add leeks or pak choi for extra flavor and texture.

Ingredients for the Thai Curry Marinade

Prepare this the night before for the best slow cooker results.

  • 3 tbsp olive oil
  • 2 tbsp sweet soy sauce
  • 2 cloves garlic, pressed
  • 1 tbsp ginger powder
  • 1 tbsp galangal powder
  • Salt and pepper to taste

Mix all marinade ingredients. Cube the chicken breasts and marinate for several hours or overnight.

Homemade Thai Curry Paste

For authentic depth, whip up this paste—better than store-bought. It's a soy sauce-based blend of spices.

Ingredients:

  • 5 tbsp sweet soy sauce
  • 2 tbsp ginger powder
  • 1 tbsp galangal powder
  • 2 cloves crushed garlic
  • 4 tbsp curry powder
  • 1 tbsp ground coriander (ketumbar)
  • 1 tsp sambal (for spice lovers)

This paste has a kick from the sambal, but it's family-friendly—adjust for kids if needed. Mix everything together; prep it ahead if desired.

Slow Cooker Instructions

Add marinated chicken to the slow cooker. Layer on chopped carrots, onions, zucchini, spring onions, and bell pepper. Stir in the curry paste.

Important: If using green beans, boil them for 5+ minutes first to neutralize lectins, or cook separately and add at the end.

Cook on low for 6 hours or high for 4 hours.

30 minutes before serving, stir in the coconut milk to prevent curdling. Finely chop and add coriander now or just before serving (my preference).

Serve with: Boiled rice, low-carb smart pasta rice, or homemade cauliflower rice.

Wok Thai Chicken Curry

The wok method is quicker for stovetop fans.

Marinate cubed chicken for 1 hour. Prepare the curry paste and chop vegetables.

Boil green beans and carrots for 15 minutes (or steam). Stir-fry marinated chicken until nearly cooked, then add zucchini, onion, spring onions, and bell pepper. Wok for 10 minutes.

Add cooked beans, carrots, coconut milk, and curry paste. Stir for 10 minutes until thickened.

Serve over rice with chopped fresh coriander.
