Soy sauce and coconut aminos are both dark, salty-sweet condiments used as seasoning and dipping sauces, but they come from different worlds: soy sauce is a fermented soybean and wheat product with deep umami, while coconut aminos is a sap-based, soy-free alternative that is milder and slightly sweeter. This guide explains exactly how they differ, when you can swap one for the other, and how to adjust recipes so the flavor and salt level still work. You will also get a simple side-by-side recipe to taste the difference yourself.
Ingredients
- 1/4 cup (60 ml) soy sauce (regular or low-sodium, see Tips)
- 1/4 cup (60 ml) coconut aminos
- 1 tsp (5 ml) rice vinegar (optional, for a quick dipping sauce)
- 1/2 tsp (2 g) sugar (optional, to balance saltiness)
- 1 clove garlic, minced (optional)
- 1 tsp (5 ml) sesame oil (optional, for aroma)
Instructions
- Set out two small bowls. Pour 1/4 cup (60 ml) soy sauce into one and 1/4 cup (60 ml) coconut aminos into the other.
- Taste each plain with a clean spoon. Note the differences: soy sauce is saltier, more savory, and has a deeper umami from fermentation; coconut aminos is thinner, milder, and noticeably sweeter with a faint coconut undertone.
- If you want to make a quick dipping sauce, add 1 tsp (5 ml) rice vinegar, 1/2 tsp (2 g) sugar, minced garlic, and sesame oil to either bowl, stir to dissolve the sugar, and let sit for 5 minutes.
- Use the sauces as a dip for dumplings, spring rolls, or grilled meat, or drizzle over rice or vegetables. Adjust the amount based on your salt preference.
Tips
- Substitution ratio: When replacing soy sauce with coconut aminos in a recipe, use the same amount (1:1) but add a pinch of salt (about 1/8 tsp per tablespoon of aminos) to make up for the lower sodium. Conversely, if using soy sauce instead of coconut aminos, reduce the salt in the dish by about half, or dilute the soy sauce with a little water.
- Low-sodium soy sauce: If you are watching sodium, low-sodium soy sauce has about 40% less salt than regular, making it a closer match to coconut aminos. However, it still contains soy and wheat, so it is not suitable for soy or gluten allergies.
- Flavor pairing: Coconut aminos works well in stir-fries, marinades, and salad dressings where a hint of sweetness is welcome. For dishes that rely on soy sauce’s deep umami (like teriyaki or ramen), add a splash of fish sauce or a pinch of mushroom powder to the aminos to mimic that savory note.
- Common mistake: Do not use coconut aminos in recipes where soy sauce is the main flavor and you expect the same saltiness—it will taste bland. Always taste and adjust seasoning at the end.
Serving Suggestions
Use the comparison sauce as a dipping sauce for potstickers, sushi, or grilled chicken skewers. Drizzle it over steamed broccoli or rice bowls, or use it as a marinade for tofu or salmon (if cooking fish, ensure it reaches 145°F / 63°C). The sauces also work well as a base for stir-fry noodles or as a finishing touch on fried rice.
Variations
- Spicy version: Add 1/2 tsp (2 g) chili flakes or a few drops of hot sauce to either sauce for heat.
- Citrus twist: Replace rice vinegar with 1 tsp (5 ml) fresh lemon or lime juice for brightness.
- Garlic-ginger sauce: Add 1/2 tsp grated ginger and 1 minced garlic clove to make a punchy dipping sauce.
- Sweet and sticky: For a glaze, simmer either sauce with 1 tbsp (15 ml) honey or maple syrup until slightly thickened (about 2-3 minutes).
Storage and Reheating
Both soy sauce and coconut aminos are shelf-stable unopened; store them in a cool, dark place. Once opened, keep them in the refrigerator to preserve freshness—soy sauce can last up to 1 year, while coconut aminos typically keeps for 6-12 months. The prepared dipping sauce (with vinegar, garlic, etc.) can be refrigerated in an airtight container for up to 3 days. Reheat only if you want a warm sauce; microwave in 10-second bursts or warm gently in a small pot. Do not leave the sauce at room temperature for more than 2 hours.
Frequently Asked Questions
Is coconut aminos healthier than soy sauce? Coconut aminos is lower in sodium (about 90 mg per teaspoon vs. 290 mg for regular soy sauce) and is gluten-free and soy-free, making it a good option for those with allergies or on a paleo diet. However, it is not a health food—it still contains sugar and calories, and its nutritional benefits are not significantly superior for most people.
Can I use coconut aminos in place of soy sauce in any recipe? Yes, in most recipes you can substitute 1:1, but expect a sweeter, less salty flavor. For savory dishes, add a pinch of salt or a splash of fish sauce (if not vegetarian) to compensate. For baking or marinades, the sweetness can be an advantage.
Does coconut aminos taste like coconut? No, it does not taste like coconut. The name comes from the coconut palm sap used to make it, but the final product has a mild, slightly sweet, and salty flavor reminiscent of a light soy sauce. The coconut undertone is very subtle.
Is coconut aminos gluten-free? Yes, coconut aminos is naturally gluten-free because it is made from coconut sap and salt, with no wheat or soy. Soy sauce traditionally contains wheat, so if you need gluten-free, look for a tamari (which is usually wheat-free) or use coconut aminos.
Why is coconut aminos more expensive than soy sauce? Coconut aminos is made from the sap of coconut flowers, which is labor-intensive to harvest and process, and it is often produced in smaller batches. Soy sauce is mass-produced from inexpensive soybeans and wheat, making it much cheaper.
Can I make coconut aminos at home? It is not practical to make a true coconut aminos at home because it requires fermenting coconut sap, which is not widely available. A quick substitute is to mix 1/4 cup soy sauce (if you can have soy) with 1 tablespoon honey and 2 tablespoons water, but this will not replicate the exact flavor or be soy-free.
