While its undeniably delicious, is green curry healthy?

Green curry is a very unhealthy dish due to its high fat content from the coconut milk and heavy usage of carbs from the rice – a serving of green curry can run up to 700 calories, largely due to the fat content from coconut milk, which is a whopping 12 grams of fat per serving, and carbs from the rice that the curry is eaten with.

💭 What is Thai Green Fish Curry?

Thai Green fish curry is a variation of Thai curry denoted by it's green color. Traditionally, it's made with Green chilis, which gives it it's green color. This particular curry is served with white fish and like most curries, is best served with a side of jasmine rice.

Similar to my yellow curry, red curry, and butternut squash curry recipe, this recipe optimizes for authentic Thai flavors while making the recipe healthy and macro-optimized.

🍎 Calories and Nutrition – Make It Healthy

In this recipe, I used key ingredient swaps from my Tips to Make Healthy Thai Curry guide to make this a more macro-friendly and calorie-conscious meal. The green curry recipe has 370 calories with 31 grams of protein, 5 grams of fat, and 46 grams of carbs.

Here's how I achieved this:

• Fish – White fish is naturally a lean protein source. I opted for cod because it has the best consistency, but any other white fish would work well too. If you like fish recipes, check out my Thai steamed fish recipe for another Thai classic!
• Coconut Milk – Use light coconut milk - a serving of light milk is 45 calories vs 120 calories from normal coconut milk due to less fat content as the light version has less coconut cream. 
• Portion sugar and seasonings mindfully – Used 1 teaspoon of sugar and 1 tablespoon of fish sauce. Both are essential to the curry flavor and 1 teaspoon of sugar is only 15 calories of sugar. 
• Portion the rice – I used 1 serving of jasmine rice at 160 calories
• Use cooking spray – Instead of traditional oil for everything that was sautéd or fried. 1 tablespoon of olive oil adds a whopping 120 calories to the dish, whereas cooking spray is 0 calories.

📋 Ingredient Notes

Fish – I used cod fillet, as it had the most optimal flakey and moist texture. You can also use other types of white fish if cod is not available.

Thai Green Curry Paste – I made green curry paste from scratch using a blender. Green curry paste is a mixture of lemongrass, shrimp paste, coriander, cumin, galangal, ginger, kaffir lime leaves, green chilis, cilantro, and turmeric.

Fresh ingredients work best here for an authentic flavor, but given how scarce these ingredients are, you can also use dried versions. You can also use store bought Thai curry paste for a shortcut – the mae ploy brand is a favorite among home cooks.

Galangal, kaffir lime leaves, and shrimp paste may be more specialized ingredients that are. harder to find. For ingredient substitutions for harder to find curry ingredients, refer the the substitutions section below.

Chilis – Green Thai Chilis are traditionally the main chili ingredient used to make green curry paste, giving it the vibrant green color. However, given the extreme spiciness of green Thai chilis and the fact that they're harder to find in US grocery stores, I substituted it with a jalapeño pepper, traditional Thai chilis, cilantro, and spinach

Light Coconut Milk – Used 1 serving of light coconut milk. This gives the curry it's signature flavor at a fraction of the calories.

Seasonings – The curry sauce is often seasoned with fish sauce, sugar, and lime juice to give it a balanced flavor. Palm sugar is what's traditionally used but both brown sugar and white sugar also work.

See my recipe card below for a complete list of the ingredients with measurements.

📖 Substitutions and Variations

Galangal sub – Galangal is a relatively harder to find herb. I was able to find it at HMart as well as my local asian markets. You can order dried galangal online or substitute by using ginger and a spritz of lemon juice.

Kaffir Lime Leaves – Kaffir lime leaves are also a harder to find herb. I've also been able to find it at HMart as well as my local Vietnamese grocery store, or find dried kaffir lime leaves online. If you cannot find it, you can just omit it.

Adjust spiciness – If you prefer a more intense spice, you can add more Thai chilis and/or use serrano peppers.

Switch up the rice with Brown rice, white rice, mixed grain rice or cauliflower rice – Health wise, they are all similar in calories and macros, with mixed grain rice slightly higher in calories (190 calories vs 160 calories for one serving). Cauliflower rice is a good option for those who prefer a low carb diet.

Switch up the protein – Green curry sauce would also go well with prawns or skinless chicken meat for an equally delicious and healthy dish.

Sauté the curry paste –  Use cooking spray and spray a skillet, then sauté the curry paste along with the garlic and onions. [Photo 3]

Add the coconut milk and fish – Turn the stove to low heat and add in coconut milk. High heat will make the milk evaporate very fast. If that happens, you can deglaze the sauce with water. Add the cod pieces in a single layer and cook for 1-2 minutes each side, or until cooked thoroughly. [Photo 4]

Season to taste – Season the curry sauce with fish sauce, sugar, and lime. Taste and adjust if needed.

Serve and enjoy – Garnish with cilantro and chili flakes if desired and serve with rice, and enjoy your delicious green curry recipe.

💭 Recipe FAQs

💡 Expert Tips

Water or stock to deglaze as needed – If the coconut milk seems to be evaporating too much, make sure the heat is lowered and deglaze the pan with water as needed

Add Water or stock To Help Form Paste – Making curry paste in a blender can be harder without a liquid agent - add water while making it to help form the paste. I added about ¼ cup.

Kaffir Lime Leaf Stem – Be sure to destem the kaffir lime leaves - the stem has a bitter flavor that can be unpleasant. To destem, fold the leave in half and cut off the stem. 

How to use lemongrass – For the curry paste, we will use the lower white half of the lemongrass stalk. Slice the lemongrass widthwise, until the purple rings begin to disappear.

🥡 Storage

Curry Paste – Homemade curry paste is great to make ahead and store. You can keep it in a closed glass container in the fridge for up to 3 weeks. Alternatively, you can store it in ice cube trays and freeze it up for up to 3 months.

Overall Dish – After you've made the dish with the coconut milk and fish, you can store it in the fridge for up to 2-3 days.
