Chicken Massaman Recipe: Thai Coconut Curry With Potatoes and Peanuts

There’s something deeply satisfying about the rich, complex flavors of a well-made Thai curry. This dish brings together tender chicken, hearty potatoes, and the nutty crunch of peanuts in a fragrant coconut sauce.

The secret lies in the balance of spices and the slow simmer that allows all the ingredients to meld together perfectly. I’ve refined this method to ensure the meat stays juicy while the potatoes absorb the aromatic sauce.

What emerges is a restaurant-quality curry with layers of flavor—sweet, spicy, and savory all at once. The peanuts add a delightful texture contrast that makes every bite interesting.

Perfect for a comforting weeknight dinner or impressing guests at a weekend gathering. Here’s how to make it right.

Ingredients for Chicken Massaman

Tender chicken, hearty potatoes, and peanuts simmer in a fragrant coconut sauce for authentic Thai flavor.

The chicken thighs are essential for juicy, flavorful meat—boneless and skinless ensure they cook quickly and absorb the sauce. Yukon Gold potatoes hold their shape better than russets during the long simmer. For the curry paste, Maesri or Thai Kitchen brands are widely available and deliver authentic flavor. Look for cans of full-fat coconut milk without additives for the creamiest results.

Need to swap the peanuts? Cashews or almonds work beautifully (toast them first for extra crunch). No tamarind paste? Lime juice with a touch of brown sugar gets you close. For a vegetarian version, chickpeas or tofu replace the chicken well. The fish sauce adds depth, but soy sauce with a pinch of sugar can substitute in a pinch.

This curry tastes even better the next day once the flavors meld. Store in an airtight container in the fridge for up to 4 days or freeze for 3 months. Reheat gently to preserve the coconut milk’s creamy texture.

Step-by-Step Instructions for Chicken Massaman

Master this method for authentic Thai flavors with rich coconut sauce and tender chicken.

Step 1: Toast Spices and Sauté Aromatics

Heat the 2 tbsp vegetable oil in a large pot over medium heat. Add the cinnamon stick and 3 whole cardamom pods, toasting for 30-45 seconds until fragrant. This wakes up the spices and infuses the oil with their complex aroma.

Add the thinly sliced onion and sauté for 4-5 minutes until soft and translucent. Then stir in the 4 cloves minced garlic cloves and 1 tbsp grated fresh ginger, cooking for 1 minute until the raw garlic smell mellows. Be careful not to burn the garlic—it should turn pale gold, not brown.

Step 2: Build the Curry Base with Paste and Potatoes

Stir in the 3 tbsp Massaman curry paste and cook for 1-2 minutes, pressing it against the bottom of the pot to deepen its flavor. This step is crucial—it removes the raw edge from the paste and intensifies its richness.

Add the 1 lb cubed Yukon Gold potatoes and stir to coat them evenly in the spiced paste. Pour in 1 cup of the 2 cups coconut milk and bring to a gentle simmer. Cook for 5 minutes, allowing the potatoes to begin softening in the aromatic sauce.

Step 3: Simmer with Chicken and Remaining Liquid

Add the 1.5 lb bite-sized boneless skinless chicken thighs to the pot, stirring to ensure they’re fully submerged in the sauce. Pour in the remaining 1 cup coconut milk, 2 tbsp fish sauce, 1 tbsp coconut sugar, and 1 tbsp tamarind paste.

Bring to a gentle simmer, then reduce the heat to medium-low. Cover and cook for 20-25 minutes, stirring occasionally, until the potatoes are tender and the chicken is cooked through. The sauce should thicken slightly and coat the back of a spoon.

Step 4: Finish with Peanuts and Garnish

Stir in the 0.5 cup roughly chopped roasted peanuts and cook for an additional 2-3 minutes to heat them through. The peanuts should soften slightly but retain some crunch. Taste and adjust seasoning—add a pinch more coconut sugar for sweetness or fish sauce for saltiness if needed.

Remove from heat and let the curry rest for 5 minutes to allow the flavors to meld. Just before serving, stir in the 0.25 cup chopped fresh cilantro, reserving a small handful for garnish. The cilantro adds a bright, fresh contrast to the rich, spiced sauce.

Dietary Considerations for These Flavors

Gluten-Free Friendly

This curry is naturally gluten-free, making it perfect for anyone avoiding wheat. All the core ingredients—chicken, potatoes, peanuts, coconut milk—contain no gluten. Just double-check your Massaman curry paste brand, as some may contain wheat flour as a thickener. I trust Maesri and Thai Kitchen for reliably gluten-free options.

Dairy-Free and Vegan

With no dairy in the original recipe, this curry works beautifully for dairy-free diets. For a fully vegan version, swap the chicken for 1.5 lbs chickpeas or extra-firm tofu and replace fish sauce with soy sauce plus 1 tsp sugar. The coconut milk provides all the creaminess you need.

Nut Allergy Substitutes

If peanuts are off-limits, simply omit them or replace with ½ cup toasted sunflower seeds for a similar crunch. Another great option is toasted coconut flakes, which complements the dish’s Thai flavors. Always check that your curry paste is nut-free if allergies are severe.

Low-Carb Adaptations

To reduce carbs, replace the potatoes with 1 lb cauliflower florets, which absorb the sauce beautifully. You could also use radishes for a low-carb alternative that holds its shape. The rest of the recipe remains unchanged, keeping all that rich, aromatic flavor.

Soy-Free Option

The fish sauce contains soy in some brands, but coconut aminos work as a perfect 1:1 substitute. For a completely soy-free version, use Red Boat fish sauce (soy-free) or increase the salt and tamarind slightly. The dish will still taste authentic and balanced.
