Ingredients

• 2 lbs (900 g) boneless, skinless chicken thighs, cut into bite-size pieces
• 1 medium yellow onion, thinly sliced
• 1 red bell pepper, sliced into strips
• 3 cloves garlic, minced
• 1 tbsp (6 g) fresh ginger, finely grated
• 2 to 3 tbsp (30 to 45 g) Thai red curry paste, adjusted to taste
• 1/2 cup (120 ml) low-sodium chicken broth
• 1 tbsp (15 ml) fish sauce
• 1 tbsp (13 g) packed brown sugar
• 1 can (13.5 oz / 400 ml) full-fat coconut milk
• 1 lime, juiced (about 2 tbsp / 30 ml)
• 1 tbsp (8 g) cornstarch mixed with 2 tbsp (30 ml) cold water, optional for thickening
• Salt, to taste
• 1/4 cup (4 g) fresh Thai basil or cilantro leaves, chopped, for garnish
• Cooked jasmine rice, for serving

Ingredient Notes

Thai red curry paste is the main source of flavor. Brands vary in heat, so start with 2 tablespoons and add more after tasting.

Full-fat coconut milk gives the sauce its body and richness. Light coconut milk works but makes a thinner curry.

Fish sauce adds savory depth. If you need a substitute, use soy sauce, though the flavor will be slightly different.

Chicken thighs stay moist during slow cooking. Boneless chicken breast can be used, but it may become drier, so check it earlier.

Equipment You’ll Need

• Slow cooker, 5 to 6 quart capacity
• Cutting board and sharp knife
• Small bowl and whisk, for the cornstarch slurry
• Ladle and serving bowls

How to Make Slow Cooker Thai Coconut Chicken Curry

1. Prep the ingredients. Thinly slice the onion, slice the bell pepper into strips, mince the garlic, and grate the ginger. Cut the chicken into bite-size pieces, about 1 to 1 1/2 inches.
2. Add the vegetables to the slow cooker. Spread the onion, bell pepper, garlic, and ginger across the bottom of the slow cooker. This keeps the vegetables from sticking and helps them cook evenly.
3. Make the base sauce. In a bowl, whisk together the chicken broth, curry paste, fish sauce, and brown sugar until the paste dissolves. Pour the mixture over the vegetables.
4. Add the chicken. Place the chicken pieces on top and gently press them into the liquid so they are mostly coated.
5. Cook on low or high. Cover and cook on LOW for 6 to 7 hours or on HIGH for 3 to 4 hours. Cooking times vary by slow cooker, so start checking near the minimum time. The chicken is done when it is opaque throughout, reaches 165°F (74°C) on a food thermometer, and shreds easily with a fork.
6. Stir in the coconut milk. Add the coconut milk during the last 30 minutes of cooking. Adding it earlier can cause it to separate or turn grainy over long cooking times. Stir gently and cover again until the curry is hot and steamy.
7. Thicken if needed. If the sauce looks thin, stir the cornstarch slurry into the curry. Switch the slow cooker to HIGH and cook for another 10 to 15 minutes, stirring once, until the sauce looks slightly glossy and coats the back of a spoon.
8. Finish with lime and salt. Stir in the lime juice and taste the curry. Add salt a pinch at a time until the flavors are balanced.
9. Serve. Spoon the curry over hot jasmine rice and top with chopped basil or cilantro.

Pro Tips for the Best Results

• Brown the chicken in a skillet first if you want deeper flavor and a slightly caramelized edge. This step is optional.
• Add the coconut milk late to keep the sauce smooth and creamy.
• Taste the curry before serving. Slow cookers can mute flavors, so a little lime juice or salt often makes a big difference.
• Cut the chicken into even pieces so they cook at the same rate.
• Use fresh lime juice instead of bottled. It tastes brighter in the finished curry.

Common Mistakes to Avoid

• Adding all the coconut milk at the start: Long cooking can make the sauce grainy or oily. Add it in the last 30 minutes.
• Overcooking the chicken: Thighs are forgiving, but very long cooking on HIGH can make them stringy. Check the chicken near the minimum cooking time.
• Using too little curry paste: Brands differ in strength. If the curry tastes flat, add another spoonful rather than adding more coconut milk.
• Skipping the acid: A squeeze of lime at the end balances the richness of the coconut milk.

Variations and Substitutions

• Chicken swap: Use boneless chicken breast or bone-in thighs. Bone-in thighs may need a longer cooking time.
• Vegetable add-ins: Add baby spinach, snap peas, or sliced zucchini during the last 30 minutes.
• Milder version: Use 1 tablespoon of red curry paste and add extra coconut milk.
• Vegetarian option: Replace the chicken with firm tofu or chickpeas, and use vegetable broth instead of chicken broth.

Serving Suggestions

Serve the curry over jasmine rice, which soaks up the sauce well. Brown rice or rice noodles also work. Add lime wedges, extra basil, sliced chilies, or chopped peanuts for crunch and color. A simple cucumber salad with rice vinegar makes a refreshing side.

Storage and Reheating

Let the curry cool to room temperature for no more than 2 hours, then transfer it to an airtight container and refrigerate. It keeps in the refrigerator for up to 3 to 4 days. To freeze, portion the curry into freezer-safe containers and freeze for up to 2 to 3 months. Thaw overnight in the refrigerator before reheating.

Reheat the curry on the stovetop over medium-low heat, stirring often and adding a splash of water or broth if it has thickened. You can also microwave it in short intervals, stirring between each one. Reheat until it is steaming hot throughout. Coconut-based sauces can separate after freezing, so stir well while reheating.

Frequently Asked Questions

Can I make this curry without a slow cooker?

Yes. Simmer the sauce base in a large pot over medium heat, add the chicken, and cook for about 15 to 20 minutes until the chicken is cooked through. Then stir in the coconut milk and simmer for a few more minutes.

Can I use chicken breast instead of thighs?

Yes, but chicken breast dries out more easily. Check it about an hour before the earliest suggested time and remove it from the slow cooker once it is cooked through.

Why did my curry turn out thin?

Slow cookers hold in moisture, so the sauce may stay thin. Use the cornstarch slurry and cook on HIGH for 10 to 15 minutes to thicken it. Next time, you can also reduce the broth slightly.

Is this curry spicy?

It has mild to medium heat, depending on the curry paste you use. Start with 2 tablespoons and add more if you want extra heat.

Can I freeze this Thai coconut chicken curry?

Yes. Freeze it in portions for up to 2 to 3 months. Reheat slowly and stir well to bring the sauce back together.
