Every summer growing up, the first really ripe mango of the season went into exactly one thing: a tall, frothy glass of mango lassi. My mom would blend it thick, top it with a pinch of cardamom, and hand it over before lunch was even on the table. That first cold sip still tastes like June to me.
These Mango Cardamom Overnight Oats take everything I love about that glass and turn it into a jar you can stir together before bed. Ripe mango folded into a creamy yogurt-and-milk base, cardamom right in the soak, and rolled oats that soften overnight into a thick, spoonable breakfast. You get the lassi flavor and the staying power of oats, ready to grab from the fridge on a busy morning.
If mango season makes you a little emotional too, and you already keep a bag of rolled oats in the pantry, this one is going to feel like it was made for you. Let’s stir it together tonight so breakfast is done before you wake up.
What Makes These Taste Like Mango Lassi
Mango lassi is a traditional Indian yogurt drink: sweet ripe mango blended with thick dahi (yogurt), a splash of milk, and often a whisper of cardamom, served cold through the hot months. The magic is the combination of mango sweetness and yogurt tang, not just fruit stirred into plain milk.
Most mango overnight oats online stop at chopped mango and almond milk. Fine for a quick jar, but it tastes nothing like a lassi. The yogurt note is missing, cardamom rarely shows up, and the jar ends up thin and one-dimensional. The trick here is to build a real lassi-style base: blend or mash ripe mango with plain yogurt and milk, sweeten lightly, and add cardamom before the oats go in. Rolled oats, chia, and a little ground flax drink up that creamy liquid overnight, so every spoonful tastes like the drink you grew up on.
That gentle sourness from the yogurt is exactly what keeps a sweet mango breakfast from tasting flat, and it is the same flavor I capture in my mango lassi recipe. If you have ever wished mango season could last a little longer, this jar is how I stretch it into weekday mornings.
Pro tip: Bloom your cardamom by using freshly crushed pods rather than old ground powder. The oils fade fast once ground, and a fresh pinch is the difference between “nice mango oats” and “this tastes like my mom’s lassi.”

- Tastes like mango lassi. Real yogurt tang, ripe mango, and cardamom in every spoonful.

- Easily vegan with plant yogurt and milk, and gluten-free with certified oats.
Ingredient Notes
Only a handful of things, and the mango is the star.
- Rolled oats: old-fashioned rolled oats hold texture best overnight. Skip steel-cut (too chewy) and instant (turns mushy). Use certified gluten-free oats if needed.
- Ripe mango: sweet, fragrant, and soft is everything here. Alphonso or Kesar pulp gives the most authentic lassi flavor, but any sweet ripe mango works. Frozen mango is great off-season if fully thawed before blending.
- Plain yogurt: thick, unsweetened. Greek yogurt makes the jar extra creamy and is the lassi backbone, so do not skip it unless you are going vegan.
- Milk: a splash to loosen the base to a pourable consistency. Any dairy or plant milk works.
- Green cardamom: the signature lassi note. Crush seeds from two to three pods, or use a small pinch of freshly ground cardamom.
- Chia seeds: 1 tablespoon per serving to bind and thicken. Optional but recommended for a scoopable set.
- Ground flax: optional, 1 tablespoon per serving for extra body and omega-3s.
- Sweetener: honey, maple, or sugar, to taste. Ripe mango does most of the work, so start light.
- Salt: a tiny pinch sharpens the mango and cardamom.
- Fresh mango: diced, for layering and topping.
- Pistachios: chopped, optional, for crunch and a pretty green contrast.
How to Make Mango Cardamom Overnight Oats
Ten minutes of hands-on time, then it sets while you sleep.
- Prep the mango. Peel and cube the ripe mango. Blend 1 cup to a smooth puree (or mash very soft mango with a fork). Set aside 1/4 cup diced mango for layering and topping.
- Whisk the lassi base. In a bowl or large jar, whisk the mango puree with yogurt, milk, sweetener, crushed cardamom, and a pinch of salt until smooth. Taste and adjust sweetness now, while you still can.
- Stir in oats, chia, and flax. Add the rolled oats, chia seeds, and ground flax if using. Stir thoroughly, let sit 5 minutes, then stir again. This second stir is what keeps chia from clumping at the bottom.
- Chill overnight. Cover and refrigerate at least 6 hours, ideally overnight, until thick and spoonable.
- Layer and serve. Spoon into jars, alternating with the reserved diced mango. Top with fresh mango, a pinch of cardamom, and chopped pistachios if you like. Stir in a splash of milk if you prefer it looser.
Tips for the Perfect Overnight Oats Texture
- Mind the ratio. About 1/2 cup rolled oats per 1 cup of liquid (yogurt + milk + mango puree) plus chia gives a thick, scoopable jar. Remember mango puree adds moisture, so start a little light on the milk.
- Always do the second stir. Five minutes after mixing, the chia starts to gel and sink. A quick re-stir keeps the oats even from top to bottom.
- The first time I made these I stirred everything once and walked away, and by morning half the chia had welded into a lump at the base of the jar. One extra stir fixes it completely, so treat that step as non-negotiable.
- Loosen in the morning. Overnight oats always firm up more than you expect. A splash of milk or yogurt before serving brings them right back.
- Chill mutes sweetness. Make the base taste a touch sweeter than you want for a drinking cup, because cold always dulls it.
Variations
Once you have the mango-cardamom base down, it is easy to play.
- Chia instead of oats: prefer a pudding-soft set? My Mango Lassi Chia Pudding is the same mango-and-cardamom breakfast in a chia base, and it is the sibling I reach for when I want something even more dessert-like.
- Vegan mango overnight oats: swap the dairy yogurt for thick coconut or cashew yogurt and use plant milk. Cashew yogurt keeps the classic lassi tang best.
- Kesar (saffron) twist: bloom a few saffron strands in warm milk before blending for a festive, golden version. If you love that flavor, you will also love my Kesar Badam Chia Pudding.
- Extra thick, shrikhand-style: use all Greek yogurt and skip half the milk for a denser jar that nods to my Mango Shrikhand (Amrakhand).
- Chai-time pair: for a spiced breakfast rotation, alternate this jar with my Masala Chai Overnight Oats on busy weeks.

Notes
Common FAQs
Can I make mango cardamom overnight oats vegan or dairy-free?
Yes, easily. Replace the yogurt with a thick unsweetened coconut or cashew yogurt and use any plant milk. Cashew yogurt keeps that signature lassi tang, while coconut adds a gentle sweetness. Everything else stays exactly the same.
How long do these last in the fridge?
Stored in an airtight jar, they keep for up to 4 days, which makes them excellent for meal prep. Add fresh mango topping only when you serve so it stays bright.
Can I use frozen mango or canned pulp?
Absolutely, and it is how I make this outside mango season. Thaw frozen mango fully before blending, and if you use sweetened canned pulp, cut back on the added sweetener. Alphonso or Kesar pulp gives the most authentic lassi flavor.
Why did my overnight oats turn out too thick or too runny?
Too thick usually means the oats and chia drank up all the liquid overnight, so stir in a splash of milk before eating. Too runny usually means too much mango moisture or not enough oats/chia, so next time add another tablespoon of oats or chia and give it more chill time.
What’s the difference between this and mango lassi chia pudding?
Same flavor family, different texture. Overnight oats use rolled oats for a familiar oatmeal-like chew. Chia pudding sets softer and more dessert-like. I keep both in rotation depending on whether I want breakfast oats or a spoonable pudding.
Do I need Greek yogurt or will regular yogurt work?
Either works. Greek yogurt makes the jar thicker and creamier. Regular yogurt is fine; you may need slightly less milk to keep the ratio right.
Can I eat them warm?
Yes. Gently warm a single serving in the microwave or on the stovetop with a splash of milk, stirring often. The mango flavor stays lovely, though I usually eat mine cold straight from the fridge like a lassi.
