What is Thai Seafood Sauce?

Thai seafood sauce is also known as nam jim seafood.

It’s very aromatic, bright, tart and the perfect pairing for seafood like oysters, shrimp, calamari, clams, fish, and more!

This Thai seafood sauce is also great with non-seafood things.

I love dipping chicken and veggies in this.

The flavors are garlicky, spicy, sour, umami, and just slightly sweet.

This nam jim dipping sauce is super easy to make and hard to mess up.

Just taste as you go and adjust it to your liking.

The Thai seafood sauce recipe I’m sharing here, in my opinion, is the perfect ratio of ingredients and balance of flavors!


Whole Foods $1 Oysters Review

Whole Foods has $1 oysters every Friday, or $12 for a dozen, which is such a great deal!

It is a Prime Member Deal valid in-store only. You have to scan your In-Store QR Code at checkout for the deal to apply.

The Whole Foods oyster deal is offered at all U.S. locations, except Hawaii locations are priced at $15 for 12 oysters.

The special price applies to all oyster varieties. I usually get the East Coast Atlantic Blue Point oysters.

They will package them in ice for you so that it stays fresh.

If you ask nicely, they will shuck them for you. However, not all Whole Foods locations will offer this service.

If you do get them shucked in store, it is important to keep them iced, and eat them as soon as possible when you get home. This is for health and safety reasons since you are eating them raw.

I like to get a dozen of these raw oysters and make this sauce to top them off!


Thai Seafood Sauce Ingredients

Before you begin making the Thai seafood sauce, you’ll need the following ingredients:

  • Fish Sauce: Fish sauce is a salty and umami sauce is made by fermenting anchovies. Since this is eaten straight out of the bottle and not used for cooking, it is important to use a high quality fish sauce. The ingredient list should only be salt and anchovies. I recommend Red Boat Fish Sauce or the Three Crabs Brand.
  • Lime: Fresh lime juice makes this sauce sour, tangy, and gives it a nice brightness which pairs really well with seafood.
  • Thai Chili: Thai chili peppers, also known as bird’s eye chili, packs a lot of spice and heat into a small pepper. This is the best pepper for this sauce. However, if you are unable to get Thai chili peppers, Fresno, serrano, or jalapeño peppers also work great. Feel free to substitute with your favorite pepper.
  • Garlic: I love adding raw garlic to sauces. It’s very aromatic and adds a nice kick and punch of flavor.
  • Ginger: Ginger adds a fresh yet warm spice to the sauce.
  • Cilantro: Fresh chopped cilantro adds a fresh, herby brightness to the overall sauce.
  • Green Onions: Green onions have a mild onion flavor that adds a bit of a bite and freshness to the sauce. If you don’t want it to be too pungent, use the green parts only.
  • Sugar: Sugar balances out the saltiness. Palm sugar is ideal for this sauce but it is not a super common ingredient to find. White sugar works well as a substitute.

Step 1: Combine Ingredients For Thai Seafood Sauce

Once you’ve gathered all the ingredients, slice chili peppers, mince garlic, grate ginger, slice green onions, and cut the lime.

Add them all into a small mixing bowl and juice the lime into the same bowl.

These suggested measurements makes about 1/3 cup of Thai seafood sauce.

  • 2-5 Thai chili peppers
  • 3 garlic cloves, minced
  • 1 inch piece ginger, grated
  • 2 tsp palm or white sugar
  • 1 green onion, sliced
  • 1 tbs fish sauce
  • 1 (2-3 tbs) lime, juiced

You can simply mix it by hand but it is best to use a mortar and pestle.

If using a mortar and pestle, first pound the dry ingredients into a paste.

Pounding everything together helps to release the flavors more and meld them all together.

If you don’t have a mortar and pestle, you can also use a food processor or mince with a knife.

Next, add in the liquids – fish sauce and lime juice.

Lastly, mix everything together.

Step 2: Taste & Adjust Thai Seafood Sauce

Finally, taste test the sauce.

Again, these measurements are just a suggestion.

Add a little of each ingredient at a time and taste test as you go.

Everyone’s taste buds and preferences are different so make you sure adjust the Thai seafood sauce to your liking.

To make it more salty, add more fish sauce. Adding more fish sauce can also help to diffuse the other ingredients, like lime or sugar, if you find that the flavors are too strong.

If you like it spicier then add more chili peppers.

Add more lime to make the sauce more tart and sour. This will also balance out and reduce the saltiness of the fish sauce.

Adjust the amount of garlic, ginger, green onion, and cilantro to your preference based on how aromatic you’d like it to be.

For a sweeter sauce, add more sugar. This also helps to reduce the saltiness.

If it is too strong or concentrated then add water to dilute as needed.

Leftovers & Storage

If you have leftover Thai seafood sauce, store in a sealed container in the fridge.

It usually keeps well for 1-3 days.

The ingredients infuse more into the sauce as it sits so it will taste even better!

However, if you store for too long, you will lose the freshness of the ingredients and the colors won’t be as vibrant.
