Lao cuisine deserves more recognition, especially with popular dishes like spicy papaya salad.
It’s one of my absolute favorite Laotian foods.
This dish features thinly sliced green papaya tossed in a dressing that perfectly balances savory, sweet, tangy, and spicy flavors.
It’s also pungent—but in the best way possible.

What is Spicy Papaya Salad?
Papaya salad, known as Som Tum in Thai and Thum Mak Hoong in Lao, is made with primarily shredded green papaya, chili, garlic, lime juice, and fish sauce.
If you’re lucky, you might also find it served with Lao plums (also known as ambarella fruit or trái cóc in Vietnamese) or pieces of preserved rice paddy crabs for extra flavor.

Its perfect balance of spicy, sour, salty, and slightly sweet flavors has made it a staple in both Lao and Thai cuisines. Enjoy it as a quick side dish or serve it with sticky rice and grilled meats for a complete meal.
I love bringing this dish to family potlucks, introducing its pungent yet delicious flavors to curious non-Asian family members for fun *wink*.

Thai vs. Lao vs. Vietnamese Papaya Salad
Papaya salad is popular across Southeast Asia, with each country offering its own unique version:
- Lao Papaya Salad (Thum Mak Hoong or Tum Mak Hoong): Lao papaya salad is known for its strong, pungent flavor due to the use of fermented fish sauce (padaek) and fermented shrimp paste. This gives it a bold, savory, and funkier taste.
- Thai Papaya Salad (Som Tum): Thai papaya salad uses clear fish sauce, resulting in a milder flavor. It’s often topped with toasted peanuts for added crunch.
- Vietnamese Papaya Salad (Gỏi Đu Đủ): Vietnamese papaya salad is even more mellow than the Thai version, with added thinly sliced beef jerky and a soy sauce-based dressing. Just like the Thai version, it too is also topped with toasted peanuts.
In this recipe, we’ll focus on a Lao-style spicy papaya salad.

What You Will Need to Make Lao Papaya Salad
To make this classic and popular Lao spicy papaya salad, gather the following ingredients:
- Green papaya: This is just simply an unripe papaya. Crunchy and refreshing, this is the foundation of the dish. It is crucial you use only unripe green papaya for that crunch. The papaya you select should always be green and firm when pressed.
- Tomatoes: For a beautiful red color. I’m using cherry tomatoes. You can also use a large tomato and cut into small pieces.
- Lime: Adds bright acidity to the dressing. You may notice lime peel in the sauce, primarily for its green color. However, avoid pounding the lime peel in the mortar and pestle too much, as it will release a bitter flavor into the sauce. I like to toss it in salad at the end to avoid the bitterness.
- Tamarind: Adds a fruity tanginess distinct from lime juice. If you don’t have tamarind juice, you can skip it and use lime juice instead. However, I find having both adds a lot of flavor. I’m using a tamarind concentrate for simplicity. You can substitute with tamarind powder or tamarind pulp, strained with hot water.
- Fermented fish sauce: A key ingredient in Lao cuisine is padaek, a rich, unfiltered fermented fish sauce that’s dark brown with a strong, pungent flavor. It provides a deep, funky umami kick characteristic of the dish. If you can’t find the Thai version, you can substitute it with the Vietnamese version, mắm nêm.
- Fish sauce: Another type of fish sauce that adds a salty flavor. This one is however filtered and clear. It’s more mellow than padaek. I like to use the Three Crabs brand.
- Thai shrimp paste: This adds another and final layer savory umami flavor. There are many brands of shrimp paste, I’m using Twin Chicken brand to keep it authentic to Laotian cuisine and Thai cuisine. If you don’t have this Thai/Lao version, you can use the Vietnamese version, Mắm Ruốc or Mắm Tôm.
- Palm sugar: Balances the dressing with caramel-like sweetness. Palm sugar comes in various sizes; I’m using small pods. If they’re too large, cut them into smaller pieces or thin slices to help them melt quickly. Pounding them in a mortar and pestle, as we’ll do in this recipe, also works well. If you can’t find palm sugar, brown sugar is a great substitute.
- Garlic: Sharp and aromatic. Fresh garlic is best.
- Thai chili peppers: Also known as Bird’s Eye Chilies for spiciness. Add as much or as little as you like.
- Optional accompaniments: pork rinds, cabbage wedges for scooping, Vietnamese ham, and snake beans (also known as long beans).

How to Hand Shred Papaya
Start by peeling the papaya with a vegetable peeler. Keep it whole to ensure the seeds remain intact. However, if handling a whole papaya is difficult, cut it into smaller pieces and remove the seeds.
You can use a julienne peeler to create thin, uniform strips, but if you’re up for the traditional method, try what the Lao people call fuk.
In Lao, fuk refers to the process of hand-shredding papaya. Despite sounding like an offensive term in English, fuk simply means “to chop.”
This technique involves using a sharp knife to make multiple vertical cuts into the papaya, then slicing it horizontally to create thin shreds.
This method produces strips of varying sizes and textures, adding a touch of authenticity to the dish.




Lao Cooking Tools: Mortar and Pestle
Papaya salad is traditionally prepared using a kohk and sahk, the Lao and Thai version of a mortar and pestle.
The mortar is tall with slender sides and made from terracotta clay, while the pestle is typically wooden. This large mortar is used to pound the ingredients and dressing together.
If you don’t have this traditional tool, any small mortar and pestle will work. Use it to pound the aromatics and make the sauce.
Once the sauce is ready, pour it over the shredded papaya. Mix and squeeze everything together with your hands to mimic the pounding action of the pestle.
How to Make Lao-Style Papaya Salad
Step 1: Prepare the Papaya
Peel the green papaya and cut into long thin strands. Transfer to an ice bath to rinse off any wax or sap, and to make the papaya shreds crunchy.

Step 2: Make the Dressing
Make the dressing in a mortar and pestle, or use a food processor if you don’t have one.

Pound the palm sugar so it breaks apart into small pieces.

Add the garlic and Thai chili peppers and pound into a rough paste.

Add lime and tamarind juice.

Add fish sauce, fermented fish sauce, and shrimp paste.

Add the tomatoes and lightly smashed them open. You can also add in the lime peel at this point just for color but that’s optional.
Step 3: Assemble
Drain the papaya from the ice bath and transfer it to a large bowl. Toss the shredded papaya with the dressing, mixing by hand and gently squeezing as you combine the ingredients.
If you have a traditional mortar and pestle, simply add the papaya shreds to the mortar and pound them together with the sauce and frequently scraping the sides down with a spoon.


Step 4: Serve
Plate the salad and serve immediately.
How to Serve Lao Papaya Salad
For an authentic experience, serve this Lao-style papaya salad with wedges of Vietnamese ham, crispy pork rinds, and bite-sized sheets of cabbage for scooping.
These accompaniments provide a variety of textures and perfectly complement the salad’s bold, tangy and funky flavors.
For the ultimate bite, use fresh sticky rice to scoop up the papaya salad. This traditional method not only absorbs the rich, savory sauce but also turns the dish into a satisfying, filling meal.
For a heartier option, pair it with grilled meats such as skewered chicken, beef, or pork.

FAQs
What if I don’t have green papaya?
Shredded green mango or cucumber can work as substitutes, though the texture and flavor will be slightly different.
I can’t find the fermented fish sauce you’re using. What can I use instead?
You can substitute it with the Vietnamese version, Mắm Nêm, a fermented anchovy paste. Keep in mind that it has a stronger, more concentrated flavor, so you’ll need to adjust the quantity to taste.
