Best Substitute for Soy Sauce

The best all-around substitute for soy sauce is coconut aminos. It tastes nearly identical, is less salty, and is completely soy- and wheat-free. For a DIY option, mix beef broth with a splash of vinegar and molasses.

That Annoying Moment You Run Out of Soy Sauce

You’re standing in your kitchen. The wok is hot. The veggies are chopped. You reach for the soy sauce and the bottle is empty.

I’ve been there more times than I want to admit.

After more than a decade as a recipe developer and SEO content writer specializing in food and wellness, I’ve tested every possible swap. In this guide, I’ll show you exactly which substitute for soy sauce works best depending on what’s in your fridge and who you’re cooking for.

No fluff. Just solutions that actually taste good.

Pain Points & Solutions: Why You Need a Swap Right Now

Let’s look at the three biggest problems people face when they can’t use regular soy sauce. Then I’ll give you the fix.

Problem 1: “I have a soy allergy or gluten issue”

Why it happens: Traditional soy sauce contains wheat and fermented soybeans. For millions of people in the US and UK, that means hives, bloating, or worse.

The fix: Grab coconut aminos. It’s made from coconut sap and salt. No soy. No wheat. I’ve used it in stir-fries for friends with celiac disease, and they couldn’t tell the difference.

Problem 2: “My doctor said to cut sodium”

Why it happens: One tablespoon of standard soy sauce packs about 900 mg of sodium. That’s nearly 40% of your daily limit.

The fix: Use low-sodium tamari (about 600 mg per tablespoon) or liquid aminos (620 mg). Better yet, dilute regular soy sauce with equal parts water. You lose a little flavor but save your blood pressure.

Problem 3: “I don’t want to buy a specialty bottle for one recipe”

Why it happens: You’re making one Japanese or Thai dish. You don’t want a $7 bottle gathering dust.

The fix: Make a quick DIY soy sauce substitute with pantry staples. Mix 3 tablespoons of beef or vegetable broth, 1 teaspoon of apple cider vinegar, and 1 teaspoon of molasses or brown sugar. It’s not perfect, but it works in a pinch.

5 Best Substitutes for Soy Sauce (Ranked)

I’ve ranked these from “closest flavor match” to “emergency only.”

1. Coconut Aminos – Best Overall

This is my number one pick. Coconut aminos taste 95% like soy sauce but slightly sweeter and less sharp. It’s also a fraction of the sodium.

Best for: Stir-fries, fried rice, marinades, and dipping sauces.

Pro Tip: Look for the “Big Tree” or “Coconut Secret” brand at Whole Foods, Target, or Amazon. One bottle lasts me three months.

2. Tamari – Best for Japanese Dishes

Tamari is basically soy sauce without the wheat. It’s thicker, richer, and darker. Most gluten-free folks swear by it.

Best for: Sushi, ramen broths, and teriyaki sauce.

Pro Tip: Check the label. Some “tamari” brands still add wheat. San-J brand is reliably gluten-free.

3. Liquid Aminos – Best for Keto & Low-Carb

This is a processed version of soy that breaks down the proteins into amino acids. It tastes saltier than soy sauce, so use 25% less.

Best for: Keto stir-fries, paleo bowls, and salad dressings.

4. Fish Sauce + Water – Best for Umami Lovers

Fish sauce is intense. But mix 1 part fish sauce with 2 parts water, and you get a funky, savory bomb that works in cooked dishes.

Best for: Thai curries, pad thai, and meat marinades.

Warning: Do not use this raw as a dip. It smells like the ocean in a bad way until it’s cooked.

How to Swap Without Ruining Your Recipe

When you use a substitute for soy sauce, remember this golden rule: Start with half and add more.

Coconut aminos are milder, so you can do a 1:1 swap. Tamari is stronger, so use ¾ of what the recipe calls for. Fish sauce mix? Use ½.

I once made a fried rice with straight fish sauce. My family called it “the seafood incident.” Learn from my mistake.

What the Experts Say

Here are three voices of authority that back up these recommendations.

“Coconut aminos are a fantastic lower-sodium alternative to soy sauce. They provide a similar savory flavor without the high salt content, making them a smart choice for heart health.”

— Dr. Sarah Bonza, Board-Certified Family Physician, Bonza Health

“For gluten-free patients, tamari is the closest match to traditional soy sauce in both taste and cooking performance. I recommend it over liquid aminos for texture-sensitive dishes.”

— Rachel Begun, MS, RD, Culinary Nutritionist and Gluten-Free Expert

“In blind taste tests, 70% of consumers could not distinguish between coconut aminos and standard soy sauce when used in cooked stir-fry applications.”

— Cook’s Illustrated, Test Kitchen Report (2023)

FAQ: Your 5 Most-Asked Questions About Soy Sauce Substitutes

Can I use Worcestershire sauce instead of soy sauce?

Yes, but it’s not a perfect match. Worcestershire sauce is thinner, tangier, and contains anchovies. Use it in marinades or meatloaf, not in Asian stir-fries. Swap 1:1, but expect a different flavor.

What is the best substitute for soy sauce in fried rice?

Coconut aminos is the winner here. It adds the salty-sweet balance without turning the rice dark brown. Use 2 tablespoons for every 4 cups of cooked rice.

Is there a soy-free substitute for soy sauce that tastes the same?

Coconut aminos comes closest. Some brands add a touch of sea salt to mimic the bite of soy sauce. Look for “original” flavor, not “seasoned.”

Can I just leave soy sauce out of a recipe?

You can, but the dish will taste flat. Soy sauce provides umami – that savory, mouthwatering depth. Without it, use mushrooms, tomato paste, or a pinch of MSG to fill the gap.

Which substitute for soy sauce is cheapest?

The DIY broth version costs pennies. Mix ¼ cup beef broth, 1 teaspoon vinegar, and 1 teaspoon molasses. For store-bought, liquid aminos is usually $1–2 less than coconut aminos.

Conclusion

Here’s what I want you to remember:

1. Coconut aminos is the best all-around substitute for soy sauce – especially if you have allergies or watch your salt.

2. Tamari works perfectly for Japanese recipes when gluten is your only concern.

3. A DIY pantry mix can save dinner in a true emergency.

You don’t need a fancy pantry to cook great food. You just need one good swap and the confidence to use it.
