This easy slow cooker Thai coconut curry is a hands-off dinner that turns chicken, vegetables, and a can of coconut milk into a creamy, mildly spicy curry. Most of the work happens in the first 15 minutes, and the slow cooker does the rest while you go about your day.
The sauce is rich and lightly sweet with a gentle heat, and the chicken becomes tender after a few hours on low. It pairs well with steamed jasmine rice and makes a satisfying meal for a busy weeknight.

Ingredients
- 1 1/2 lb (680 g) boneless, skinless chicken thighs, cut into bite-size pieces
- 1 can (13.5 oz / 400 ml) full-fat coconut milk
- 2 tbsp (30 g) red or yellow Thai curry paste, adjusted to taste
- 1 small yellow onion (about 6 oz / 170 g), sliced
- 1 red bell pepper (about 6 oz / 170 g), cut into strips
- 1 medium carrot (about 3 oz / 85 g), sliced into thin coins
- 1 cup (90 g) broccoli florets, added near the end
- 1 tbsp (15 ml) fish sauce

- 1 tbsp (15 ml) fresh lime juice
- 1 clove garlic, minced
- Fresh cilantro or Thai basil, for serving
- Cooked jasmine rice, for serving
Ingredient Notes
Full-fat coconut milk gives the curry a silky body. Light coconut milk works but produces a thinner sauce. Curry paste varies widely in heat, so start with 2 tablespoons and add more after tasting at the end. Fish sauce adds savory depth; you can use soy sauce for a vegetarian-friendly swap, though the flavor will be different. Chicken thighs stay juicier than breasts during long cooking, which is why they are recommended here.
Equipment You’ll Need
- A 5 to 6 quart slow cooker
- A cutting board and sharp knife
- A medium bowl for mixing the sauce
- A ladle and serving bowls
How to Make Slow Cooker Thai Coconut Curry
- Prepare the ingredients. Cut the chicken into bite-size pieces, about 1 inch (2.5 cm). Slice the onion, pepper, and carrot so they are similar in size. Keep the broccoli separate for later.
- Make the sauce base. In a medium bowl, whisk the coconut milk with the curry paste until smooth. The paste should fully dissolve with no clumps of spice, which takes about 1 minute.
- Add the sauce flavorings. Stir in the fish sauce, brown sugar, lime juice, and garlic. Taste a small spoonful. It should be balanced between salty, sweet, sour, and spicy. Adjust as needed.
- Layer the slow cooker. Place the onion and carrot on the bottom, then the chicken, then the bell pepper. Pour the coconut sauce over everything. Stir gently so the chicken is coated.
- Cook on low for 6 to 8 hours or high for 3 to 4 hours. Cook until the chicken is no longer pink in the center and reaches 165°F (74°C) on an instant-read thermometer. Cooking times vary by slow cooker, so start checking at the earliest time.
- Add the broccoli. During the last 20 to 30 minutes, stir in the broccoli florets. Cover and let them steam until bright green and tender-crisp.
- Taste and adjust. Stir well and add more lime juice, fish sauce, or a pinch of sugar if needed. The curry should look creamy and coat the back of a spoon.
- Serve. Ladle the curry over jasmine rice and top with fresh cilantro or Thai basil.
Pro Tips for the Best Results
- Stir the curry paste into the coconut milk before adding it to the slow cooker. This prevents lumps and spreads the flavor evenly.
- Cut the chicken into uniform pieces so they cook at the same rate.
- Add the broccoli late. Early additions turn soft and grayish.
- Taste only after the cooking is finished, since flavors concentrate during long cooking and can taste different at the end.
- Finish with a squeeze of lime juice just before serving to brighten the sauce.
Common Mistakes to Avoid
Overcooking the vegetables. Bell peppers and carrots hold up well, but broccoli and other soft vegetables need to be added near the end.
Using too much curry paste. Paste strength varies by brand. Start small and add more only if the curry needs it.
Skipping the thermometer. Slow cookers differ in heat output. Checking the chicken temperature is the most reliable way to confirm it is done.
Lifting the lid too often. Each time you open the lid, heat escapes and the cooking time gets longer.
Variations and Substitutions
- Shrimp version: Use 1 lb (450 g) peeled shrimp and add them during the last 15 to 20 minutes.
- Vegetarian version: Replace the chicken with chickpeas and firm tofu, and use vegetable broth in place of fish sauce if needed.
- Spicy version: Add a sliced red chili or extra curry paste.
- Vegetable swaps: Snap peas, zucchini, or baby corn work well in place of broccoli.
Serving Suggestions
Serve the curry over jasmine rice, brown rice, or rice noodles. Add lime wedges, sliced chili, or chopped peanuts for extra texture. A simple cucumber salad on the side adds a cool, crisp contrast.
Storage and Reheating
Let leftovers cool slightly, then store them in an airtight container in the refrigerator for up to 3 to 4 days. The curry can be frozen for up to 2 to 3 months, though coconut-based sauces may separate slightly after thawing. To reheat, warm it gently in a saucepan over medium-low heat, stirring occasionally, and add a splash of water or coconut milk if the sauce has thickened.
Frequently Asked Questions
Can I cook this on high to save time?
Yes. High heat usually takes 3 to 4 hours, while low heat takes 6 to 8 hours. Check the chicken temperature to confirm it is fully cooked.
Can I use chicken breast instead of thighs?
You can, but chicken breast dries out more easily during long cooking. Reduce the cooking time and check it early.
Why is my curry too thin?
Coconut milk thins out if you use a light version or add extra liquid. Remove the lid for the last 30 minutes of cooking to let the sauce reduce.
Can I make this ahead of time?
Yes. Prepare the sauce and chop the vegetables the night before, then refrigerate them separately. Add everything to the slow cooker in the morning.
Is this curry spicy?
It has a mild to moderate heat that depends on the curry paste you choose. Red curry paste is usually spicier than yellow.
