Massaman Potato Curry — Easy Thai Curry with Supermarket Ingredients

#W2Kitchen #massamancurry
Massaman potato curry made with just supermarket ingredients – a rich, coconut-based Thai curry built around potatoes, pantry spices and tinned coconut milk instead of hard-to-find lemongrass, galangal and shrimp paste. We toast ground spices (coriander, cumin, cinnamon, clove, nutmeg, white pepper and chilli), sweat onion and garlic into a quick curry paste, then fry everything gently in reduced coconut milk fat before braising chunks of waxy potato until they’re tender inside and coated in a thick, glossy sauce. The base of this curry is naturally vegetarian, and you can keep it vegetarian by seasoning with salt and soy sauce instead of Worcestershire sauce, or make it fully vegan by sticking to soy, lemon juice and sugar while still getting classic Massaman richness from coconut and potato starch.
🥔 Ingredients (Serves 3–4)
• Potatoes (medium-waxy: Maris Piper / Yukon Gold style) — 800 g, peeled and cut into 3–4 cm chunks
• Coconut milk — 1–2 tins (you’ll reduce it hard at the start; exact brand doesn’t matter)
• Onion or shallot — 1 medium, finely chopped (or pounded)
• Garlic — 3–4 cloves, minced (or pounded)
• Ground coriander — 2 tsp
• Ground cumin — 1 tsp
• Chilli powder — 1–2 tsp (to taste)
• Cinnamon — ¼ tsp
• Ground clove — ⅛ tsp (or a small pinch)
• Nutmeg — a small pinch
• White pepper — ¼ tsp
• Seasoning (choose 1, or mix):
• Salt — 0.6% of potato weight (≈ 5 g for 800 g potato)
• Soy sauce — use enough to hit the same salt target
• Worcestershire sauce (*non-vegetarian*) — to taste (for “shrimp paste” vibe)
• Water — enough to start with ~1 cm depth in the pot, plus extra later
• Optional “extra mile”: green cardamom pods — 3–5
• Finish: honey or brown sugar — 1–2 tsp; lemon juice — 1–2 tsp; optional unwaxed lemon zest

Method

1. Toast spices: In a dry pan, briefly toast the ground spices (coriander, cumin, chilli, cinnamon, clove, nutmeg, white pepper) until fragrant. Set aside.

2. Reduce coconut milk: In a cold pot, add coconut milk and bring to a gentle simmer over low heat. Keep simmering until it turns thick and you start to see oil splitting.

3. Add aromatics: Stir in onion/shallot and garlic. Cook on low until their moisture cooks off and the coconut oil is gently frying the solids (little steam, light sizzling).

4. Bloom spices + season: Add the toasted spices and stir on low so they don’t burn. Season using your chosen route (salt and/or soy and/or Worcestershire), aiming for 0.6% salt relative to potato weight.

5. Coat potatoes: Add potatoes and mix well to coat in the curry fat.

6. Steam-braise (stingy water): Add no more than ~1 cm of water. Bring to a boil, then lid on and lowest heat. Cook 30 minutes, stirring once halfway and scraping the bottom.

7. Build the sauce: Once the potatoes have released their moisture, add water and/or more coconut milk to reach your preferred sauciness. Scrape up any fond.

8. Optional cardamom finish: Add cardamom pods, lid on, and cook 20–30 minutes more until potatoes are tender.

9. Balance: Stir in honey (or brown sugar) and lemon juice. Optional lemon zest right at the end. Taste and adjust seasoning
