Best Soy Sauce Substitutes (With Ratios)
The best soy sauce substitute is tamari, used 1:1. It is a Japanese-style soy sauce made with little or no wheat, so it tastes slightly richer and less sharp, and many brands are certified gluten-free.
Soy sauce substitutes
| Substitute | Amount per 1 tbsp soy sauce | Best for | Why it works |
|---|---|---|---|
| Tamari | 1 tbsp | Everything, gluten-free cooking | Brewed soy sauce with similar salt and umami |
| Coconut aminos | 1 tbsp + pinch of salt | Soy-free, lower-sodium cooking | Fermented coconut sap with savoury-sweet flavour |
| Liquid aminos | 1 tbsp | Stir-fries, dressings | Soy protein broken into amino acids; similar saltiness |
| Miso paste | 1 tsp miso + 2 tsp water | Soups, glazes, marinades | Fermented soybean paste with deep umami |
| Fish sauce | 1/2 tbsp + 1/2 tbsp water | Southeast Asian dishes, marinades | Intense salt and glutamate; funkier flavour |
| Worcestershire sauce | 1 tbsp | Marinades, stews, burgers | Umami from anchovies, with tang and spice |
| Maggi seasoning | 1/2 to 1 tbsp | Soups, fried rice, eggs | Salty, meaty hydrolyzed-protein seasoning |
What makes soy sauce taste the way it does
Traditional soy sauce is made from cooked soybeans and roasted wheat, inoculated with koji mould (Aspergillus oryzae), then mixed with salt brine and fermented for months. Koji enzymes break soy proteins into amino acids, especially glutamate, the main driver of umami. Starches become sugars, and lactic bacteria and yeasts add acidity and alcohol-derived aromas.
Over the long aging, those sugars and amino acids undergo the Maillard reaction, producing the dark colour and roasted, almost meaty aroma. The final sauce is roughly 14–18% salt, which is why a little seasons a lot.
A good substitute therefore needs salt plus glutamate, and ideally some fermented or browned depth. Tamari, miso and fish sauce have all three. Coconut aminos has less salt and glutamate, so it tastes milder.
Salt and allergy notes
- Gluten: regular soy sauce contains wheat. Choose tamari labelled gluten-free, or coconut aminos.
- Soy allergy: tamari, miso and liquid aminos are all soy. Use coconut aminos or fish sauce.
- Low sodium: reduced-sodium soy sauce has about 40% less salt. Coconut aminos has even less.
When NOT to swap
- Dark soy sauce for light, 1:1: dark soy will make a dish very dark and sweet. Use it only for colour, a teaspoon at a time.
- Fish sauce in vegetarian dishes or for anyone avoiding fish.
- Worcestershire in dipping sauces, sushi or poke: its vinegar and spice are distracting.
- Coconut aminos in salt-dependent recipes, like brines or soy-cured eggs, won't season enough without added salt.
Questions
Is tamari gluten-free?
Usually, but not always. Tamari is traditionally made with little or no wheat; check that the label says gluten-free, because some brands include wheat.
Is coconut aminos a good soy sauce substitute?
Yes for soy-free and lower-sodium diets. It is sweeter and has roughly a third of the sodium, so use it 1:1 and add a pinch of salt if the dish tastes flat.
What is the difference between light and dark soy sauce?
Light (regular) soy sauce is thinner and saltier and is used for seasoning. Dark soy sauce is aged longer, often with molasses, so it is thicker, sweeter and mainly used for colour.
Can I use Worcestershire sauce instead of soy sauce?
In marinades and stews, yes, 1:1, but it is tangier and less salty. It won't work in dipping sauces or sushi.
