Everything You Need to Know About Green Papaya
Green papaya is simply unripe papaya: the same fruit as the sweet orange kind, picked while its flesh is still firm, pale and crunchy. It has a mild, neutral taste, so although it’s technically a fruit, it’s cooked like a vegetable. In Thailand, it’s the star of som tam (green papaya salad). It’s also a good source of vitamin C and fibre, and it contains papain, a natural enzyme that breaks down protein.

What is Green Papaya?
Green papaya is the unripe form of the tropical fruit Carica papaya, which grows on papaya trees that can reach several metres tall. Ripe papaya has sweet, orange-red flesh, but green papaya is harvested earlier, while its flesh is firm, crunchy and neutral in taste. It’s pear-shaped, usually weighing between 650g and 1kg, with smooth green skin and a hollow core of white seeds, which turn black as the fruit ripens.
Because it isn’t sweet and stays crisp, green papaya is used like a vegetable. In Thailand, it’s the base of som tam, a salad that balances the four essential Thai flavours: sweet, sour, salty and spicy. Try our Som Tam Thai Green Papaya Salad.
How to Prepare Green Papaya
Green papaya is easy to prepare once you know how:
Peel it. The skin is fairly soft, so a vegetable peeler works well. You may see a white, milky liquid. This is natural papaya latex, and you can wipe it away. If you have sensitive skin, wear gloves.
Remove the seeds. Cut the papaya in half and scoop out the white seeds with a spoon.
Shred the flesh. Use a julienne peeler or a coarse grater. For the traditional Thai method, hold the peeled papaya in one hand, make lots of long, thin cuts into the flesh with a sharp knife, then slice off the top layer into a bowl. Repeat until it’s all shredded into fine, crunchy strands.
Cooking with Green Papaya
Green papaya’s neutral flavour makes it perfect for soaking up bold dressings. In som tam, the shredded papaya takes on palm sugar, fish sauce, lime juice and chillies, while its crunch gives a refreshing contrast to the spicy, tangy dressing.
It’s also used in soups, stews and stir-fries, where it keeps its bite and absorbs the other flavours. In southern Thailand, you’ll often find it in sour curry. Try it with our Mae Jum Sour Curry Paste.
Where to Buy and Store Green Papaya
In the UK, green papaya can be hard to find in mainstream supermarkets, but Asian grocery stores usually stock it, especially those catering to Thai and Southeast Asian communities.
Choose one with smooth, bright green skin that feels firm, with no soft spots or blotches. If the skin is turning yellow, it’s starting to ripen. It’s still edible, but it won’t have the crisp texture you want for som tam.
Store green papaya in a plastic bag in the fridge. If you’re keeping it for more than a few days, wrap it in kitchen paper to absorb excess moisture.
Can’t find it? Green mango is the best substitute, with a similar firm, crunchy texture and a tart flavour. Cucumber or swede can work in some recipes, although they won’t match green papaya exactly.
Green Papaya Benefits
Green papaya is a nutritious addition to a balanced diet:
A source of vitamin C, which supports the normal function of the immune system.
A source of fibre, which supports healthy digestion.
Contains papain, a natural enzyme that breaks down protein. That’s why green papaya is used as a natural meat tenderiser.
Contains vitamin A, folate and potassium, alongside antioxidants found naturally in fruit and vegetables.
Low in calories, and its mild flavour carries other ingredients well, which makes it a light base for salads.
A note on pregnancy: unripe papaya contains latex, and pregnant women are commonly advised to avoid it. If you’re pregnant, speak to your doctor or midwife before eating green papaya.

From Jum’s Kitchen
One of the loveliest things about cooking Thai food at home is how it changes the way you shop. You start noticing the Asian grocers you used to walk past, and suddenly you’re discovering ingredients you’d never heard of a year ago. Green papaya is one of those gateway ingredients. It opens the door to a whole new way of thinking about salads, texture and flavour balance, and it’s a fruit that cooks like a vegetable, so you’re free to play.
If you do get your hands on one, treat it well: keep it cold, use it within a few days, and don’t be afraid to go beyond som tam. It’s brilliant in stir-fries, lovely in soups and surprisingly good in pickles. Our pastes give you the foundation. The rest is up to you, and that’s exactly how it should be.
Hi Winsome, cooking green papaya is similar to cooking butternut squash about 10-20 minutes if boiled depending on the size of the cut.
