Som Tum – Authentic Thai Green Papaya Salad Recipe
1. Introduction
If there’s one dish that embodies the soul of Thai street food, it’s Som Tum. Fresh, crunchy, tangy, sweet, salty, and spicy all at once, this iconic green papaya salad is beloved across Thailand and beyond.

Whether you’re new to Thai cuisine or already in love with its flavors, Som Tum is a must-try. In this recipe, I’ll guide you through the ingredients, step-by-step preparation, variations, and tips for enjoying this authentic dish at home.
2. Ingredients Breakdown
Here’s what you’ll need to make a classic Som Tum:
- Green Papaya (unripe): Crisp and slightly tart; the star ingredient.
- Garlic: Crushed for bold flavor.
- Bird’s Eye Chilies: Adds signature Thai heat. Adjust to taste.
- Palm Sugar (or brown sugar): Balances the salty and sour elements.
- Fish Sauce: Provides salty, umami depth.
- Lime Juice: Freshly squeezed for bright acidity.
- Cherry Tomatoes: Adds sweetness and juiciness.
- Green Beans: Crunchy texture to complement papaya.
- Roasted Peanuts: For nutty crunch.
Substitutions & Options:
- Use carrots or cucumber if green papaya is unavailable.
- For a vegetarian version, replace fish sauce with soy sauce or tamari.
- Add dried shrimp for authentic street-style flavor.
3. Step-by-Step Instructions
- Prep the Papaya: Peel and shred unripe papaya into thin strips. Soak in cold water for 10 minutes to keep it crisp.
- Make the Dressing Base: In a large mortar, pound garlic and chilies until broken down.
- Add Seasonings: Mix in palm sugar, fish sauce, and lime juice. Pound lightly to dissolve sugar.
- Add Vegetables: Toss in cherry tomatoes and green beans. Gently bruise them to release juices.
- Combine with Papaya: Add shredded papaya and toss everything together, pounding lightly so flavors absorb.
- Finish: Top with roasted peanuts and serve immediately.
Tip: Don’t over-pound the papaya—just bruise it enough to soak up the dressing.
4. Tips and Variations
- Som Tum Thai (Classic): Balanced with peanuts and dried shrimp.
- Som Tum Lao: Stronger flavors with fermented fish sauce (pla ra).
- Som Tum Ponlamai: A fruit version with mango, pineapple, or apple.
- Protein Boost: Add salted crab or grilled shrimp for extra richness.
- Milder Option: Reduce chilies or use larger red chilies for color without overwhelming heat.
5. Serving Suggestions
Som Tum is best enjoyed fresh as part of a Thai meal. Try it with:
- Sticky rice (Khao Niew) to balance the spice.
- Grilled chicken (Gai Yang) or pork skewers.
- Thai omelet (Kai Jeow) for a comforting combo.

- Prep Ahead: Shred papaya in advance and keep it in cold water in the fridge for up to 2 days.
7. Recipe Notes
