Mild Thai Curry with Chicken and Coconut Milk

Mild Thai curry is a gently spiced, coconut-milk curry with tender chicken, vegetables, and the fragrant flavors of Thai red curry paste. This approachable version is served over rice, with lime and fresh herbs to brighten the creamy sauce; Thai curries vary by region and household, so the recipe is a mild home-style take rather than a claim to one definitive version.

Ingredients

1 lb (450 g) boneless, skinless chicken thighs, cut into 1-inch (2.5 cm) pieces
1 tbsp (15 ml) neutral oil, such as canola or avocado oil
1 small yellow onion (about 5 oz / 150 g), thinly sliced
2 garlic cloves (about 6 g), finely minced
1 tbsp (6 g) finely grated fresh ginger
1 tbsp (15 g) mild Thai red curry paste
1 can (13.5 oz / 400 ml) full-fat coconut milk, well shaken
1 cup (240 ml) low-sodium chicken broth
1 tbsp (15 ml) fish sauce
1 tsp (4 g) packed light brown sugar
1 medium red bell pepper (about 5 oz / 150 g), seeded and cut into strips
1 medium carrot (about 3.5 oz / 100 g), thinly sliced on the diagonal
1 cup (125 g) green beans, trimmed and cut into 1-inch (2.5 cm) pieces
1 cup (30 g) baby spinach, loosely packed
1 tbsp (15 ml) fresh lime juice, plus lime wedges for serving
¼ tsp (1.5 g) fine salt, or to taste
¼ cup (10 g) roughly chopped fresh cilantro leaves
1 scallion (about 15 g), thinly sliced
3 cups (about 450 g) cooked jasmine rice, for serving

Instructions

Prepare the ingredients. Cut the chicken into evenly sized pieces so they cook at a similar rate. Slice the onion, pepper, carrot, and green beans, then mince the garlic and grate the ginger. Shake the coconut milk can before opening it. Measure out the curry paste, broth, fish sauce, and sugar. Have cooked rice ready to warm and serve; the 20-minute prep estimate includes chopping and measuring, not cooking rice from dry.
Soften the onion. Set a large, deep skillet or medium Dutch oven over medium heat and add the oil. When it shimmers, add the onion and cook for about 4 minutes, stirring occasionally, until it has softened and looks translucent around the edges. Keep the heat moderate: browned onion can make the finished curry taste more roasty and less delicate.
Bloom the aromatics and paste. Add the garlic, ginger, and red curry paste. Stir continuously for 1 minute, scraping the bottom of the pan so the paste warms in the oil without scorching. This brief step releases the paste’s aromatic flavor. If it begins to stick or darken, lower the heat and stir in a spoonful of the coconut milk.
Coat the chicken. Add the chicken pieces and stir for about 4 minutes, turning them so they are coated with the paste and begin to lose their raw, glossy appearance on the outside. They do not need to be cooked through at this stage. Pour in the coconut milk and broth, then stir in the fish sauce and brown sugar. Bring the mixture to a gentle simmer, not a hard boil.
Simmer until the chicken is done. Cook gently for about 9 minutes, stirring once or twice. Check the thickest chicken pieces with a food thermometer; the USDA FSIS safe minimum internal temperature for poultry is 165°F (74°C). If any pieces have not reached that temperature, continue simmering and check again after a minute or two. The sauce should bubble softly and the chicken should be cooked through.
Cook the vegetables. Add the carrot and bell pepper and simmer for 5 minutes. Stir in the green beans and cook for 3 minutes more, or until the vegetables are tender but still have a little bite. Add the spinach and stir for about 1 minute, just until wilted. If you prefer softer vegetables, give the carrots and beans another minute or two before adding the spinach.
Season and serve. Take the pan off the heat and stir in the lime juice. Taste the sauce before adding salt, since curry paste, broth, and fish sauce can all be salty. Add the ¼ teaspoon salt only if needed. Spoon the curry over warm jasmine rice and finish with cilantro, scallion, and lime wedges.

Tips

Keep the heat gentle. “Mild” depends on the curry paste as well as the amount used; some red pastes are noticeably hotter than others. Start with the listed tablespoon, and check the package if you are cooking for someone sensitive to spice. You can stir in a little more paste after the curry simmers, but it is harder to take heat away once it is in the pot.
Choose full-fat coconut milk for a creamy sauce. Light coconut milk works if you want a thinner, less rich curry, but the sauce will have less body. Shake the can before opening, and do not worry if the cream and liquid look separated; they will blend as the sauce warms.
Use a thermometer rather than judging chicken by color. Cut the pieces to a similar size and check one of the larger pieces in its center. If the chicken reaches temperature before the vegetables are tender, you can lift it onto a clean plate while the vegetables finish, then return it to the pan. Avoid letting the curry boil vigorously, which can make chicken less tender and cause the coconut sauce to separate.
Adjust the balance at the end. Lime adds freshness, brown sugar rounds out sharp or salty flavors, and fish sauce brings savory depth. Add these in small amounts and taste between additions. If the sauce seems too thick, loosen it with a splash of broth; if it seems thin, let it simmer gently for a few minutes before adding the spinach.

Serving Suggestions

Serve the curry in shallow bowls over warm jasmine rice so the rice catches the coconut sauce. If jasmine rice is not available, basmati or another long-grain rice is a practical stand-in, though it will be less floral. A simple side of sliced cucumber, lightly dressed greens, or steamed broccoli adds a crisp, fresh contrast without competing with the curry. Set lime wedges on the table so each person can adjust the brightness of their bowl.

For a fuller spread, offer extra cilantro, scallions, and thinly sliced red chili separately. Keeping chili on the side lets everyone choose their own heat level without changing the mild base. If serving the curry as part of a meal with several dishes, plan on smaller rice portions and let guests take extra sauce and vegetables as they like.

Variations

Swap the protein: Use an equal amount of boneless, skinless chicken breast, cut into pieces, and check that it reaches 165°F (74°C). For a vegetarian version, replace the chicken with 14 oz (400 g) pressed, cubed firm tofu and use vegetable broth; brown the tofu first if you want a firmer exterior. Chickpeas also work: add one drained 15 oz (425 g) can with the vegetables, since they only need to warm through.

Change the vegetables: Broccoli florets, zucchini, mushrooms, snow peas, or cubed sweet potato can stand in for some of the listed vegetables. Cut dense vegetables small and add them early enough to become tender; delicate vegetables such as zucchini and snow peas need only a few minutes. Keep the total amount close to the recipe’s roughly 4 cups of vegetables so the sauce-to-filling balance stays pleasant.

Adjust the curry paste: Thai red curry paste is the source of the dish’s characteristic fragrant, savory flavor, and its heat varies among brands and batches. If you cannot find a mild red paste, a mild Thai yellow curry paste is a useful substitute, though it will give the curry a warmer, more turmeric-forward flavor. Ordinary curry powder is not an exact replacement because it lacks the fresh, aromatic ingredients in Thai curry paste. Add a small amount first and taste before adding more.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in a covered, shallow container. The curry keeps for 3 to 4 days in the refrigerator. Store rice separately when possible so it does not absorb all the sauce; refrigerate it promptly as well. For longer storage, freeze the curry in airtight portions for up to 2 months for best quality. Coconut milk may look grainy or separated after freezing, but gentle reheating and stirring usually bring the sauce back together.

Reheat only the portion you plan to eat, either in a saucepan over medium-low heat or in the microwave in a covered, microwave-safe dish. Stir occasionally and add a splash of broth or water if the sauce has thickened. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer, and avoid repeatedly cooling and reheating the full batch. Warm rice separately until steaming hot.

Frequently Asked Questions

Is Thai red curry paste always spicy?
Not necessarily. Its heat level varies by recipe and product, and even a mild paste can have a little warmth. Start with the amount listed, taste after the curry simmers, and serve extra chili separately rather than making the whole pot hotter.

Can I make this curry without fish sauce?
Yes. Replace the tablespoon of fish sauce with 1 tablespoon (15 ml) of soy sauce or tamari. The curry will still taste savory, but it will lack some of fish sauce’s distinctive fermented depth. Use a lower-sodium option if you have one, and taste before adding the optional salt.

Can I make it ahead?
Yes. You can cook the curry a day ahead, cool it promptly, and refrigerate it for up to 3 to 4 days total. For the freshest vegetable texture, stop cooking the vegetables while they still have a little bite and reheat gently. Add a squeeze of lime and fresh herbs just before serving.

How can I thicken the sauce?
Let it simmer uncovered for a few minutes before adding the spinach, stirring occasionally so the bottom does not catch. The sauce will also thicken slightly as it cools. Avoid adding a large amount of flour or cornstarch, which can make the texture heavy and mute the bright coconut-and-lime flavor.

Can I use chicken breast instead of thighs?
Yes. Cut it into evenly sized 1-inch pieces and use the same method, checking the thickest piece with a thermometer until it reaches 165°F (74°C). Breast meat can dry out if it simmers for too long, so begin checking near the end of the stated simmer and remove it from the heat once it is safely cooked.
