From the MyKitchenBank Kitchen

A silky, aromatic green curry sauce made by tempering store-bought or homemade green curry paste in coconut milk, then balancing heat with lime juice, fish sauce, and fresh basil. This versatile sauce clings beautifully to proteins and vegetables, delivering the bright, herbaceous notes that define Thai green curry. Use it to finish cooked chicken, shrimp, tofu, or vegetables, or simmer them directly in the sauce for deeper flavor.

Steps

Before you start

Have all ingredients measured and ready (mise en place)
Use full-fat coconut milk for the richest sauce
Squeeze fresh lime juice just before cooking
If using homemade curry paste, have it ready to go

1
Bloom the paste
- Heat a medium saucepan (2–3 quart) over medium heat.
- Add the green curry paste and cook it without stirring for 1 minute to dry out the spices slightly, releasing their volatile oils.
- You'll smell the green chiles and herbs come alive.

Ready when: Paste darkens slightly and becomes fragrant
Tip: Blooming the paste in a dry pan intensifies its flavor before the liquid is added.
2
Temper with coconut milk
- Whisk 1/4 cup (60 ml) of the coconut milk into the paste, stirring constantly for 30 seconds to create a smooth paste-cream mixture.
- This prevents lumps from forming when you add the remaining liquid.

Ready when: Paste and coconut milk are fully blended with no lumps
Tip: Whisking vigorously breaks down any small lumps of paste and ensures even distribution.
3
Add remaining liquid
- Pour in the remaining coconut milk (about 1 1/4 cups / 300 ml) and the water, stirring well.
- Bring the mixture to a gentle simmer over medium heat, stirring occasionally.

Ready when: Small bubbles break the surface steadily; sauce steams gently
Tip: A gentle simmer, not a rolling boil, keeps the sauce silky and prevents the coconut milk from breaking.
4
Simmer and infuse
- Once simmering, reduce the heat to medium-low and let the sauce bubble gently for 5–6 minutes, stirring occasionally.
- The sauce will deepen in color and the flavors will meld together.

Ready when: Sauce is noticeably thickened, fragrant, and takes on a deeper green hue
Tip: Stir occasionally to prevent a skin from forming on the bottom and ensure even cooking.
5
Season with fish sauce and lime
- Stir in the fish sauce (1.5 teaspoons / 7.5 ml) and fresh lime juice (2 tablespoons / 30 ml).
- Taste the sauce and add more fish sauce or lime to your preference—a balanced curry sauce should be savory, slightly tangy, and not overwhelmingly salty.
+ Show details− Hide details
Ready when: Sauce smells noticeably brighter; you taste both savory depth and citrus lift
Tip: Add fish sauce and lime gradually and taste as you go—it's easier to add more than to pull it back.
6
Add sweetness (optional)
- If your sauce tastes too sharp or salty, stir in palm sugar or brown sugar (1/2 teaspoon / 2.5 g) to round out the flavors.
- This is entirely optional and depends on your curry paste brand and personal taste.

Ready when: Sugar dissolves completely and sauce tastes harmonious
Tip: Different curry paste brands vary in saltiness and heat; adjust sweetness accordingly.
7
Finish with basil
- Remove the pan from heat.
- Stir in the torn Thai basil leaves just before serving.
- The residual heat will soften them slightly while preserving their fresh, licorice-like aroma.

Ready when: Basil is gently wilted but still bright green
Tip: Add basil off heat so it stays fragrant and doesn't turn dark; a long simmer mutes its delicate flavor.

Tips

Use a full-fat, canned coconut milk (shake the can first) for the silkiest texture. Lite coconut milk will yield a thinner, less luxurious sauce.
If your curry paste is very thick or chunky, strain the finished sauce through a fine-mesh sieve for a smoother, silkier result.
This sauce pairs beautifully with poached chicken, grilled shrimp, pan-seared tofu, or roasted vegetables. Serve over jasmine rice or with rice noodles.
Taste and adjust as you go. Different brands of green curry paste vary dramatically in heat, saltiness, and herbaceous intensity—there's no shame in tweaking the final seasoning to suit your palate.

Make ahead

Store the sauce (without the basil) in an airtight container in the refrigerator for up to 5 days. Reheat gently over low heat, stirring occasionally, until steaming. Stir in fresh basil just before serving. You can also freeze the sauce for up to 3 months; thaw overnight in the refrigerator and reheat gently.

Storage & reheating

Room temperature: not recommended (coconut milk spoils quickly). Refrigerator: up to 5 days in an airtight container. Freezer: up to 3 months. To reheat: warm over low heat on the stovetop or in the microwave (30-second bursts, stirring between), then add fresh basil.

Substitutions

fresh Thai basil leaves → fresh cilantro leaves or a combination of cilantro and mint. Cilantro brings a brighter, more herbaceous note. Mint adds cooling contrast. Thai basil is traditional; other herbs shift the flavor profile noticeably.
fish sauce → soy sauce or tamari (same amount). Fish sauce provides umami and salt; soy sauce does the same but with a slightly different depth. Use this if you prefer to avoid fish or need a vegetarian option.
fresh lime juice → lemon juice or rice vinegar (same amount). Lime is traditional and bright; lemon is milder. Rice vinegar adds a subtly sweet tang. Adjust to taste.
unsweetened full-fat coconut milk → heavy cream or full-fat Greek yogurt (use 1 cup cream + 1/4 cup water). Cream will make a richer, less traditional sauce with less herbaceous depth. Yogurt adds tang and also works but will curdle if boiled; stir it in at the end and heat gently.
