I first had aloo posto at a friend’s home in Kolkata, served simply with steamed rice and a thin dal, and I remember thinking how something so minimal could taste so comforting. There’s no onion, no garlic, no heavy spice blend just potatoes, poppy seeds and a few pantry staples, yet it’s one of the most-loved dishes in Bengali homes. I make this now whenever I want a light, no-fuss meal that still feels special.
What is Aloo Posto?
Aloo posto is a Bengali dish of potatoes cooked in a creamy, lightly spiced poppy seed (posto) paste. It’s a niramish, or no onion-no garlic, preparation, traditionally cooked in mustard oil, which gives it a distinct pungent aroma. The result is a mild, slightly nutty curry that’s usually eaten as a side dish rather than the main event of a meal.
Where Aloo Posto Comes From
This dish comes from West Bengal, where poppy seeds have been used in cooking for generations, especially in the summer months when a light, cooling meal is preferred. Posto dishes are considered a mark of a well-stocked Bengali kitchen, and aloo posto in particular is often the first posto recipe home cooks learn, since potatoes are always on hand. It’s typically served as part of a Bengali thali alongside dal, rice and a vegetable fry.
Health Benefits of Poppy Seeds
- Poppy seeds are a good source of healthy fats, calcium and magnesium, which support bone health.
- They contain fibre, which aids digestion.
- They’re rich in manganese and copper, minerals involved in metabolism and energy production.
- Because they’re used in small quantities, they add nutrition without significantly increasing the calorie count of the dish.
Ingredients:
- 4 medium potatoes, peeled and cut into thin batons
- 3 tbsp white poppy seeds (posto), soaked in warm water for 20 minutes
- 2-3 green chillies
- 1/2 tsp nigella seeds (kalonji)
- 3 tbsp mustard oil
- 1/2 tsp turmeric powder
- Salt to taste
- A pinch of sugar (optional)
Instructions:
Step 1: Make the poppy seed paste
Drain the soaked poppy seeds and grind them with 1-2 green chillies and a little water into a smooth, thick paste.
Step 2: Temper the oil
Heat mustard oil in a kadhai until it just starts to smoke, then let it cool slightly. Add nigella seeds and let them crackle.
Step 3: Cook the potatoes
Add the potato batons, turmeric and salt. Sauté on medium heat for 5-6 minutes until the potatoes are lightly golden at the edges.
Step 4: Add the posto paste
Stir in the poppy seed paste and a splash of water. Cover and cook on low heat for 10-12 minutes, stirring occasionally, until the potatoes are fully tender.
Step 5: Finish
Add a slit green chilli and a pinch of sugar if you like a subtle sweetness. Cook uncovered for 2 more minutes until the mixture thickens slightly, then take off the heat.
Tips:
Always soak the poppy seeds well and this makes them easier to grind into a smooth paste and removes any bitterness. Cutting the potatoes into thin, uniform batons helps them cook evenly. Mustard oil is key to the authentic flavour here, so try not to substitute it if you can help it.
