Mango Coconut Dal — Sri Lankan-Inspired One-Pot Recipe

The week raw mango shows up on our counter, our kitchen quietly shifts. Out comes the peeler for Aam Panna, yes, but also the small bowl of diced kairi I keep aside for savoury things. One of my favourite ways to use it is in a pourable, thinner dal where the mango keeps things bright, coconut milk rounds the sour edge, and a mix of vegetables simmers in the pot the way you often see in Sri Lankan-style lentil curries: carrots, beans, maybe a little pumpkin, all in the same bowl as the lentils.

Mango coconut dal here is not a thick mash. Toor dal cooks soft with raw green mango in extra water, then you loosen it further with coconut milk (no grated coconut paste). A quick tempering of mustard, cumin, and curry leaves ties it to the South Indian and island kitchen flavours I grew up around. If you already love a spinach-forward pot like my palak dal, think of this as your summer sibling: more broth, more vegetables, still weeknight friendly.

If you want another Gujarati style mango dish on the table, fajeto (mango kadhi) is a beautiful tangy curry to bookmark for the same season.

Why You’ll Love This Mango Coconut Dal

• Pourable consistency: lighter than a mashed dal, closer to a thin curry you can ladle over rice
• Coconut milk instead of grated coconut: silky, no blender paste step
• Mixed vegetables in one pot, Sri Lankan-inspired (carrot, beans, peas, optional pumpkin or ash gourd)
• One-pot friendly: pressure cooker or Instant Pot for the lentils, then a short stove simmer for veg and coconut milk
• Naturally vegan and gluten free when you use oil in the tempering and gf hing if needed
• Pairs beautifully with rice: try it with Instant Pot jeera rice for an easy thali night

Ingredients for Mango Coconut Dal

Serves 4

For the dal

• 1 cup (200g) split pigeon peas (toor dal / arhar dal), rinsed until water runs clearer
• 3.5 to 4.5 cups water (more water = thinner dal; start at 4 cups if you like it soupy)
• 3/4 to 1 cup peeled and diced raw green mango (about 1 small mango; taste a piece for sourness)
• 1/2 teaspoon turmeric powder
• 1/4 teaspoon hing (asafoetida), optional; skip for strict gluten free if your brand contains wheat, or use gf hing
• 1 teaspoon fine salt, plus more to taste

Mixed vegetables (Sri Lankan-style mix; adjust to what you have)

• 1 medium carrot, peeled and diced small (about 3/4 cup)
• 8 to 10 green beans, trimmed and cut into 2 cm / 1 inch pieces
• 1/2 cup green peas (fresh or frozen)
• Optional: 1/2 cup peeled diced pumpkin, winter squash, or ash gourd (winter melon)
• Optional: 1 small wedge of drumstick (moringa), scraped and cut into fingers, if you use it in your kitchen

Coconut milk (replaces grated coconut)

• 1 can (about 400 ml) full-fat coconut milk, or 1.5 to 2 cups from a carton, shaken well
• If you only have light coconut milk, use the full can and simmer a few minutes longer so flavour concentrates, or use half light + half full fat

Heat and aroma

• 1 to 2 green chillies, slit lengthwise (simmer in the dal; remove before serving if you prefer mild)
• Optional: 1 small pandan leaf knot, or 2 bruised lemongrass stalks (outer layers removed), for extra Sri Lankan aroma. Skip if you do not keep these at home.

For the tempering

• 2 tablespoons neutral oil or coconut oil
• 1 teaspoon mustard seeds
• 1 teaspoon cumin seeds
• 1 sprig curry leaves (10 to 12 leaves)
• 1 to 2 dried red chillies, broken (optional)
• 2 tablespoons chopped coriander, for garnish

Optional balance

• 1 teaspoon jaggery or sugar, only if your mango is very sharp

Test note: The first time I made this I used a full cup of very sour mango and skipped jaggery. It was delicious but almost too sharp on the tongue. Now I start with 3/4 cup, taste after cooking, then add the rest in simmer if I want more punch.

How to Make Mango Coconut Dal

Step 1: Pressure cook the dal and mango

Rinse the toor dal well. In a pressure cooker or Instant Pot inner pot, combine dal, 4 cups of the water (reserve the rest for thinning later), diced raw mango, turmeric, hing (if using), and 1 teaspoon salt. Add carrot dice now so it softens evenly with the lentils.

Pressure cooker (stovetop): Cook on medium heat for 3 to 4 whistles, then let pressure fall naturally. The dal should be very soft.

Instant Pot: High pressure 9 minutes, natural release 10 minutes, then quick release any remaining pressure.

Whisk the dal lightly just until it flows and the mango mostly breaks in. You are aiming for a thin, pourable base, not a thick paste. If it still looks tight, whisk in reserved hot water 1/4 cup at a time.

Step 2: Simmer mixed vegetables

Transfer the pot to the stove (or use Sauté on the Instant Pot). Add green beans, peas, optional pumpkin or ash gourd, optional drumstick, and the slit green chillies (plus optional pandan or lemongrass). Simmer uncovered 8 to 12 minutes until the beans are tender but still green and the dal is clearly brothy. Stir occasionally. Fish out pandan or lemongrass if you used them.

Step 3: Coconut milk (do not boil hard)

Reduce heat to low. Pour in coconut milk and stir once. Warm through 3 to 5 minutes at a gentle simmer. A hard rolling boil can split coconut milk, so keep it lazy. Taste: add salt, extra water if you want it even thinner, or a teaspoon of jaggery if the mango reads too sharp.

Step 4: Tempering

Heat oil in a small pan. Add mustard seeds and let them pop. Add cumin seeds, curry leaves, and dried red chilli if using. Count to five once the cumin smells fragrant, then pour the tempering over the dal and stir.

Garnish with coriander and serve hot.

Tip from experience: Pour tempering onto dal that is still gently steaming. The sizzle wakes up the curry leaves and the whole pot smells like a proper home kitchen.

Serving Ideas

This dal loves plain rice, jeera rice, or a simple phulka. The thinner style is especially nice over rice with a wedge of lime on the side. For a Gujarati-leaning thali night at our place I sometimes add a dry shaak and a small bowl of something sweet after, almost like a mini festival plate. If you want a second dal on the menu for variety, mag ni chutti dal is a softer, sweeter Gujarati-style moong dal that contrasts nicely with the sharp mango here. For dessert in mango season, Easy Mango Shrikhand (Amrakhand) is a no-stove favourite on our table.

Leftovers stay loose if you stored them with enough liquid. Coconut milk can look separated after the fridge: stir well while reheating on low and add a splash of water if needed.

Why Raw Mango and Lentils Work Together

Raw mango brings vitamin C and a bright acidity that cuts through the starchiness of toor dal. Coconut milk adds body without turning the pot into a heavy mash, especially when you keep water generous and vegetables in the bowl. Together you still get plant protein and fiber from lentils plus extra fiber from the mixed veg, in a meal that feels light enough for warm evenings.

If you are building an iron-forward vegetarian menu, this dal is not the hero iron dish the way spinach dal is, but it still belongs in rotation. For iron-rich ideas, browse iron-rich vegetarian recipes alongside another bowl of palak dal.

FAQs

Q1. Can I use ripe mango instead of raw?
Not in the same way. Ripe mango breaks down into sweetness and can make the dal taste muddy with toor. If you only have ripe mango, reduce quantity sharply and add a squeeze of lime at the end for acidity, or use tamarind pulp instead (see below).

Q2. What if I do not have raw mango?
Use 1 to 2 teaspoons tamarind paste dissolved in a little warm water, stirred in with the coconut milk step. You will miss the fresh mango aroma but the sour profile still works.

Q3. Can I make this vegan?
Yes. Keep the tadka in oil, skip ghee entirely, and confirm your hing is gluten free if needed.

Q4. My dal is still too thick
Add hot water in 1/4 cup increments after pressure cooking, before coconut milk, until it pours like a thin curry. Then add coconut milk. If it thickens too much after coconut milk, thin with a little hot water, not more coconut milk alone, or the coconut flavour can overpower.

Q5. How long does it keep?
Up to 3 days in an airtight container in the refrigerator. Reheat gently. Coconut milk can separate: stir well. Freezing is okay; texture of beans softens slightly.

Q6. Can I use moong dal instead of toor?
Yes. Moong cooks faster: reduce Instant Pot time to about 6 minutes high pressure with natural release, or 2 whistles stovetop, then check softness. You may need slightly less water for the same pourable feel.

Q7. Which vegetables are essential for “Sri Lankan style”?
There is no single official list in a home kitchen. Carrot + beans + peas is the backbone I use most. Pumpkin or ash gourd and drumstick are common in island-style mixed veg curries when you have them. Skip what you do not like; keep cook times in mind (add softer veg later).

Closing

I hope this mango coconut dal finds you on one of those evenings when you want comfort without heaviness, and something that actually tastes like mango season in a savoury bowl. If you try it, tell me: do you like yours extra sour, or balanced with a little jaggery?
