Ingredients

• 1.5 lb (680 g) boneless, skinless chicken thighs
• 1 can (13.5 oz / 400 ml) full-fat coconut milk
• 1 cup (240 ml) low-sodium chicken broth
• 2 tbsp (30 g) red curry paste, adjusted to taste
• 1 medium onion (about 6 oz / 170 g), thinly sliced
• 1 red bell pepper (about 6 oz / 170 g), cut into strips
• 1 cup (about 90 g) broccoli florets
• 2 cloves garlic, minced
• 1 tbsp (15 ml) fish sauce
• 1 tbsp (12 g) brown sugar
• 1 tbsp (15 ml) fresh lime juice
• Fresh basil or cilantro, for garnish
• Cooked jasmine rice, for serving

Quantities are estimates for a standard 6-quart slow cooker and serve about 4 people. The original notes did not list measurements, so adjust the curry paste and fish sauce to your taste.

Ingredient Notes

Chicken thighs stay tender and juicy during long, slow cooking. Breasts can dry out, so thighs are the better choice here.

Coconut milk gives the curry its creamy body. Full-fat coconut milk is richer, while light coconut milk makes a thinner sauce.

Red curry paste provides most of the flavor. Brands vary a lot in heat, so start with less and add more after cooking if needed.

Fish sauce and lime juice bring savory depth and brightness. Add the lime juice at the end, since slow cooking can dull its fresh flavor.

Equipment You’ll Need

• Slow cooker (4 to 6 quart)
• Cutting board and chef’s knife
• Medium bowl and whisk
• Large spoon or spatula

How to Make Slow Cooker Thai Coconut Curry

1. Prepare the vegetables. Slice the onion into thin half-moons and cut the red bell pepper into strips about 1/4 inch (6 mm) wide. Set the broccoli aside for later.
2. Trim the chicken. Pat the chicken thighs dry with paper towels and cut away any large pieces of fat. Cut them into 1 to 2 inch (2.5 to 5 cm) pieces so they cook evenly.
3. Make the sauce. In a medium bowl, whisk together the coconut milk, chicken broth, curry paste, minced garlic, fish sauce, and brown sugar. Keep whisking until the curry paste fully dissolves and the mixture looks smooth with no lumps.
4. Layer the slow cooker. Spread the onion and bell pepper across the bottom of the slow cooker. Add the chicken pieces on top, then pour the sauce evenly over everything.
5. Cook the curry. Cover and cook on low for 4 to 6 hours, or on high for 2 to 3 hours. These are estimates, since slow cookers vary. The chicken is done when it reaches 165 F (74 C) inside and pulls apart easily with a fork.
6. Add the broccoli. About 30 minutes before serving, stir in the broccoli florets and cover again. The broccoli should be bright green and tender-crisp, not mushy.
7. Finish with lime. Turn off the slow cooker and stir in the lime juice. Taste the sauce and add more fish sauce, sugar, or curry paste if needed.
8. Serve. Spoon the curry over hot jasmine rice and garnish with torn basil or chopped cilantro.

Pro Tips for the Best Results

• Whisk the curry paste into the coconut milk before pouring it into the slow cooker. This prevents clumps of paste from sitting in the bottom.
• Keep the chicken pieces in an even layer on top of the vegetables so they cook at the same rate.
• Avoid lifting the lid during cooking. Each time you open it, the heat escapes and adds time.
• Add the broccoli late so it keeps its color and texture.
• Taste before serving. Slow cooking mellows flavors, so the sauce often needs a little more lime or fish sauce at the end.

Common Mistakes to Avoid

• Using breasts instead of thighs: Lean breast meat tends to turn dry and stringy after hours of cooking.
• Cooking the broccoli all day: Added at the start, it turns soft and loses its color.
• Skipping the lime: Without a bit of acid at the end, the curry can taste heavy and flat.
• Using too much curry paste at once: Heat concentrates during slow cooking, so start with a smaller amount and adjust later.

Variations and Substitutions

• Shrimp version: Replace the chicken with raw shrimp and add them during the last 15 to 20 minutes of cooking.
• Tofu version: Use firm tofu cut into cubes and pressed dry. Use vegetable broth to keep it vegetarian.
• Different vegetables: Bamboo shoots, snap peas, or sweet potato chunks work well. Add quick-cooking vegetables late.
• Milder curry: Use a mild yellow curry paste for a gentler flavor.

Serving Suggestions

Serve the curry over jasmine rice to soak up the sauce. Brown rice or rice noodles also work. Add a squeeze of lime, a sprinkle of chopped peanuts, or a few sliced green onions for extra texture. A simple cucumber salad on the side adds a cool, crisp contrast.

Storage and Reheating

Store leftover curry in an airtight container in the refrigerator for up to 3 to 4 days. Let it cool slightly before refrigerating. The curry can be frozen for up to about 2 to 3 months, though the coconut milk may separate slightly after thawing. To reheat, warm it gently on the stove over medium-low heat, stirring occasionally, or microwave it in short bursts. Add a splash of broth if the sauce has thickened too much.

Frequently Asked Questions

Can I make this curry without a slow cooker?

Yes. Simmer the same ingredients in a covered pot over low heat for about 30 to 40 minutes, until the chicken is cooked through and tender.

Why is my curry too thin?

Slow cookers hold in moisture, so the sauce can stay thin. Remove the lid for the last 20 to 30 minutes on high, or stir in a small amount of cornstarch mixed with cold water.

Is this curry spicy?

It has a mild to medium heat that depends on the curry paste you choose. Use less paste for a milder dish.

Can I use frozen chicken?

It is best to thaw chicken before slow cooking. Frozen chicken takes longer to reach a safe internal temperature, and it can stay in the unsafe zone for too long.

What can I use instead of fish sauce?

Soy sauce or tamari works as a substitute, though the flavor will be a little different. Add a bit less salt elsewhere if you use it.
