Shrimp paste is fermented ground shrimp or krill blended with salt, then aged for weeks to deliver concentrated umami, salt, and funk.
Thai kapi packs up to 647 mg of free glutamic acid per 100g, the source of its savory punch.
This guide ranks 9 substitutes with exact ratios, vegan swaps, and buying tips.
What Is Shrimp Paste and Why It’s Hard to Replace
This fermented condiment combines ground krill, salt, and time to build three flavors at once: deep savory umami, sharp salinity, and a pungent oceanic funk no single swap matches.
Finding the right shrimp paste substitute starts with understanding what you lose. The ingredient goes by kapi in Thailand, belacan in Malaysia, terasi in Indonesia, and bagoong in the Philippines. Each version delivers the same three-part backbone, which is why one-ingredient swaps fall short.
The Flavor Profile: Umami, Salt, and Funk
Three elements work together. Fermentation breaks shrimp proteins into glutamate for umami, salt preserves and seasons, and volatile compounds create the funky aroma fading once cooked.
- Umami: Free glutamic acid runs as high as 1,508 mg/100g in Indonesian terasi, registering as pure savory depth.
- Salt: A 3–20% salt concentration drives the salinity and preserves the paste for years.
- Funk: Esters, aldehydes, and pyrazines build the briny aroma, which mellows dramatically after dry-roasting.
One study recorded a 32-fold jump in umami attributes when belacan entered a traditional Malaysian dish Longdom Publishing. No bottled sauce hits all three notes alone.
Common Uses in Thai and Southeast Asian Cooking
A single teaspoon anchors red and green curry pastes, nam prik kapi dipping sauce, and shrimp paste fried rice, across Southern Thai cooking where almost every savory dish includes it.
Nam prik kapi, shrimp paste blended with chilies, lime, garlic, and palm sugar, ranks among Thailand’s most iconic condiments Eating Thai Food. The dish you cook decides which swap performs best.
Quick Comparison: 9 Shrimp Paste Substitutes at a Glance
Nine swaps cover every kitchen and diet. Each trades some authenticity for convenience, vegan compatibility, or allergy safety, so the winner shifts with your recipe and pantry stock.
Substitute Comparison Table
| Substitute | Flavor Match | Vegan | Ratio (per 1 tsp paste) | Best For |
|---|---|---|---|---|
| Dried shrimp powder | 5/5 | No | 1:1 + oil | Curry pastes, nam prik |
| Fish sauce | 4/5 | No | 1 tbsp | Soups, stir-fries |
| Anchovy paste | 4/5 | No | ½ tsp | Dipping sauces, marinades |
| Vegan fish sauce | 3–4/5 | Yes | 1:1 | Soups, stir-fries |

How to Read the Ratios
Every ratio listed is a starting point, not a fixed rule. Fermented products swing widely in saltiness across brands and batches.
- Taste early and often: Add half the swap, taste, then build up.
- Cut added salt by up to 50% with high-sodium options like anchovy paste and fish sauce.
- Account for liquid: Reduce other liquids when a sauce replaces a solid paste.
- Layer for depth: Pair weaker swaps with a pinch of seaweed or mushroom powder.
Salt levels vary so much by age and brand My Kitchen Gallery that tasting beats measuring every time.
1. Fish Sauce — The Closest Everyday Swap
Both come from fermented seafood and salt, so this thin amber liquid carries the same glutamate-driven savoriness, minus the dense funk and body of the original paste.
Best Uses and Conversion Ratio
The fish sauce replacement ratio is straightforward, with one rule on salt.
- Ratio: Use 1 tablespoon fish sauce per 1 teaspoon shrimp paste, roughly a 3:1 swap by volume.
- Reduce salt: Fish sauce holds 1,160–1,400 mg sodium per tablespoon, so cut other added salt.
- Best dishes: Soups like tom yum, stir-fries, and blended curry pastes where the liquid disappears.
Flavor Trade-offs
Shrimp paste carries an amino-acid-nitrogen content roughly twice fish sauce, so the liquid reads milder and thinner. In fully cooked dishes the gap nearly vanishes. In raw nam prik or thick relishes, the missing body shows.
For rounded depth in stir-fries, add Golden Mountain Seasoning Sauce, a Thai staple since 1954 made from 75–85% fermented soybeans Tasting Table. It runs salty, so use a light hand.
2. Miso Paste — The Best Vegan All-Rounder
Fermented soybeans generate the same protein-broken-down umami as shellfish, fully plant-based. The result delivers deep savory depth with a spreadable texture close to the original, ideal for vegan kitchens.
The miso paste substitute is the strongest single vegan alternative to shrimp paste for everyday cooking.
Choosing Red vs. White Miso
The color you grab decides the intensity of your dish.
- Red miso (aka miso): Ferments 6 to 18+ months, building a bold, earthy funk closest to shrimp paste. Use it for curry pastes and dark marinades.
- White miso (shiro miso): Ferments weeks to 3 months, staying mild and slightly sweet. Reserve it for pale sauces and delicate stir-fries.
- Salt: Both hold around 10–12% salt, so sodium stays comparable either way Chef JA Cooks.
Conversion Ratio and Tips
Start with a 1:1 swap, one teaspoon miso per teaspoon shrimp paste, then adjust.
- Bridge the ocean note: Stir in crumbled nori or wakame, or a splash of vegan fish sauce.
- Wake the aroma: Sauté the miso in oil first to mimic toasted, wok-cooked paste.
Red miso skews soy-forward rather than briny Vegan Punks, so the seaweed step matters in raw applications.
3. Fermented Bean Paste & Doenjang
Korean and Chinese fermented soybean pastes age for a year or more, building an earthy, salty pungency closer to shrimp paste’s funk than any other plant-based option.
Korean Doenjang as a Funky Match
Doenjang ferments in earthenware onggi jars for a minimum of one year, producing a paste far funkier and more pungent than Japanese miso. This doenjang alternative delivers the aggressive funk vegan cooks miss most.
- Ratio: Start with ½ the amount of shrimp paste called for, since doenjang runs saltier.
- Reduce salt: Cut added soy sauce or salt in the recipe to compensate.
- Best dishes: Braises, stews, doenjang-jjigae, and bold dipping sauces. Blend with nori for the oceanic note.
Chinese Fermented Bean Paste Options
Chinese fermented bean paste offers a closely related route. Pixian doubanjiang, produced since 1688, blends fava beans, soybeans, Sichuan chilies, and salt into a salty, funky base with moderate heat.
Aged versions of 3 years or more carry measurably deeper umami than young batches Omnivore’s Cookbook. Bloom either paste in hot oil before adding liquids to fully open the flavor.
4. Vegan Fish Sauce & Seaweed-Based Swaps
Seaweed supplies briny, oceanic glutamate without shellfish, the same compound Kikunae Ikeda isolated from kombu in 1908. Blended with miso, it mimics both the salt and the sea note.
This category suits shellfish allergies and strict plant-based diets best.
DIY Seaweed Umami Blend
A simple seaweed substitute paste rebuilds shrimp paste depth from three plant ingredients.
- The blend: Mix 1 tbsp vegan fish sauce, 1 tbsp dark miso, and 1 tsp ground dulse or nori.
- Why it works: Miso thickens the mix to a paste-like body while adding fermented funk.
- Direct seaweed swap: Use twice the volume of seaweed when replacing paste alone.
Kombu’s white surface coating is mannitol, a savory sugar alcohol Tasting Table.
Store-Bought Vegan Fish Sauce Brands
Ready-made vegan fish sauce drops in at a 1:1 ratio for soups and stir-fries.
- Ocean’s Halo: Kelp-based, soy-free, organic, stocked at Whole Foods, Kroger, and Albertsons.
- Squid Brand Vegan Fish Sauce: Fermented from Korean kombu and organic shiitake.
- 24Vegan, Au Lac, Sozyë, Tofuna Fysh: Soy or seaweed bases, all shellfish-free VegNews.
5. Soy Sauce, Tamari & Other Quick Pantry Fixes
These pantry staples add salt and savory backbone but no fermented marine funk. Reach for them as emergency fixes, boosting depth with mushroom powder or tomato paste.
When to Reach for Tamari (Gluten-Free)
Tamari is the gluten-free pick, brewed almost entirely from soybeans while standard soy sauce uses up to 50% wheat.
- Ratio: Swap 1:1, but dilute soy sauce with equal water first to tame the salt.
- Stronger umami: Tamari holds 37% more soy protein than soy sauce, with lower sodium San-J.
- Add body: Stir in mushroom powder or a dab of tomato paste, both high in glutamate.
Boosting Umami with Anchovies or Oyster Sauce
For seafood eaters, two boosters close the funk gap fast.
- Anchovy paste: Use ½ teaspoon per teaspoon of shrimp paste. It runs potent, so restraint wins.
- Oyster sauce: Made from oysters, soy, and sugar, it brings sweet umami suited to stir-fries. Adjust for the added sweetness Jack Slobodian.
How to Choose the Right Substitute for Your Dish
Two questions decide everything: does your dish need paste-like body, and do you avoid animal products? Match texture to texture, then adjust salt and liquid for the swap.
By Diet: Vegan, Vegetarian & Allergy-Friendly
Your dietary line narrows the field quickly for any Thai cooking substitute.
- Vegan and vegetarian: Dark miso or doenjang at 1:1, seaweed blends at 2:1, or vegan fish sauce at 1:1.
- Shellfish allergy: Miso, doenjang, vegan fish sauce, and dried shiitake powder are all shellfish-free.
- Gluten-sensitive: Tamari diluted with equal water, or shiitake mushroom powder for multi-allergy homes.
Thai-made vegan shrimp pastes taste closer to doenjang than to Japanese white miso Messy Vegan Cook, so prioritize dark bean pastes.
By Dish: Curry Paste, Dipping Sauce, or Stir-Fry
The application matters as much as the flavor.
| Dish | Best Swap | Note |
|---|---|---|
| Red/green curry paste | Dark miso (1:1) or doenjang (½:1) | Cut added salt by half |
| Nam prik dipping sauce | Anchovy paste or seaweed-miso | Keep the thick body |
| Stir-fry | Fermented bean paste | Avoid waterlogging the wok |
| Tom yum soup | Vegan fish sauce or shiitake liquid | Dish is already liquid |

FAQ
Can I make Thai curry without shrimp paste?
Yes. Amplify fresh aromatics like lemongrass, galangal, makrut lime leaves, and toasted coriander seeds, then swap 1 teaspoon red miso for the shrimp paste at a 1:1 ratio. Brands like Aroy-D already omit it for vegan labeling.
Is there a shrimp paste substitute for shellfish allergies?
Several work well. Miso paste tops the list at a 1:1 ratio with zero shellfish. A blend of 1 tsp red miso, ½ tsp soy sauce, and dried seaweed flakes closely mimics the briny depth. Vegan fish sauces from Oatah and Lazy Kao are fully shellfish-free.
What’s the best vegan shrimp paste substitute?
Red miso wins for versatility at 1:1, ideally sautéed in oil to wake its aroma. Doenjang matches the funk best at ½ the amount (½:1). Seaweed at double the volume adds the oceanic note, and vegan fish sauce drops into liquid dishes.
Can I just leave shrimp paste out of a recipe?
Omitting it produces a flatter, less complex dish. Compensate by caramelizing aromatics longer, adding soy sauce or tamari, or stirring in mushroom powder. For curry, toasted whole spices and fresh galangal close most of the gap.
How much fish sauce equals one teaspoon of shrimp paste?
Use 1 tablespoon of fish sauce per teaspoon of shrimp paste, a roughly 3:1 swap. Because fish sauce holds 1,160–1,400 mg sodium per tablespoon, reduce other added salt and taste before serving, since brand strength varies.
Does miso taste like shrimp paste?
Not exactly. Miso delivers the same deep fermented umami through soybean protein breakdown, but the flavor reads soy-forward rather than briny. Adding crumbled nori or wakame introduces the oceanic note miso lacks, narrowing the gap considerably.
Which substitute is closest to authentic shrimp paste?
Dried shrimp powder mixed with a little oil scores 5/5 for intensity and keeps the crustacean note. For non-vegetarian cooks needing paste-like body, it beats fish sauce. Among plant-based options, doenjang carries the closest funk.
