Everything good about a mango lassi, in a jar you can eat with a spoon. Ripe mango blended with curd and cardamom, soaked into oats overnight. No sugar added.

Ingredients
- 1 cup (90 g) rolled oats
- 1 cup (165 g) ripe mango, chopped (Alphonso, Banganapalli or Kesar)
- 1 cup (245 g) fresh curd
- ½ cup (120 ml) milk
- 1 tbsp (12 g) chia seeds
- ¼ tsp cardamom powder
- A pinch of salt
- ½ cup (80 g) mango, diced, to top
- 1 tbsp (8 g) pistachios, chopped, to top
Method
- 1Blend the chopped mango, curd, milk, cardamom and salt until completely smooth. Taste it: this is your lassi, so it should be sweet enough to drink as it is.
- 2In a bowl or straight into two jars, stir the lassi with the oats and chia seeds until no dry oats remain. It will look runny; that is correct.
- 3Cover and refrigerate for at least 6 hours, or overnight, until the oats are soft and the mixture is thick and spoonable.
- 4In the morning, stir and add a spoon of milk if it has set too firm.
- 5Top with diced mango and chopped pistachios and eat cold.
Notes from the Department
- If your mango is sour, blend in 1–2 tsp honey or 2 soaked dates; it will then have added sugar.
- Use fresh, mild curd. Sour curd plus overnight soaking makes the jar sharply tangy.
- Off-season, use 1 cup unsweetened mango pulp; check the tin, as many are sweetened.

Why this works
A mango lassi is already most of an overnight oats recipe: fruit, curd, milk and cardamom. Blending them first and pouring the lassi over the oats means the mango flavour runs through every spoonful, rather than sitting in chunks on top. The oats and chia soak up the liquid in the fridge and set into something thick, cold and creamy.
Ripe mango is sweet enough that this needs no sugar. Alphonso and Kesar are the most fragrant; Banganapalli and Totapuri work but taste milder. A pinch of salt sounds odd in a sweet jar, but it makes the mango taste brighter.
Swaps
Use Greek yogurt or hung curd for a thicker, more tangy jar, and add an extra ¼ cup milk. For a vegan version, use coconut yogurt and almond or oat milk. Quick oats soften faster, in about 2 hours, but lose their bite. A pinch of saffron or a few drops of rose water take it into mango shrikhand territory.
For gluten-free overnight oats, use certified gluten-free oats.
Storage and serving
Covered jars keep 3 days in the fridge, so make two batches on Sunday night. Add the fresh mango and nuts just before eating. Do not freeze; the curd separates. For a summer breakfast on the move, take the jar and a spoon. Serve it with a handful of roasted nuts or seeds if you want something to chew alongside. The Department of Summer considers this a reasonable use of mango season.
Questions people ask
- Can I use frozen mango for overnight oats?
- Yes. Thaw it for 10 minutes or blend it straight from frozen with the curd; the lassi will be colder and slightly thicker. Check the pack: some frozen mango is sold in sugar syrup.
- Can I make mango lassi overnight oats without curd?
- Use the same amount of milk or almond milk instead. It will taste more like a mango milkshake than a lassi and set slightly looser, so add an extra 1 tsp chia.
- How long do overnight oats last in the fridge?
- Up to 3 days in a covered jar. The texture softens each day, so keep the toppings separate and add them fresh.
