Combine the liquids: In a mixing bowl or mason jar, pour in the soy sauce, rice vinegar, vegetarian oyster sauce, and water.
Sweeten & balance: Add the honey sriracha, adjusting slightly if you like more or less sweetness or spice (taste as you go).
Add aromatics & heat: Stir in the garlic powder and onion powder.
Incorporate sesame flavor: Pour in the toasted sesame oil and sesame seeds and stir to integrate. Or, If you're using a mason jar, shake it until all of the ingredients are evenly combined.
Check & adjust: Taste — if it’s too sharp, a drop more honey helps. Too mild? A splash more soy or sriracha.
Use immediately or store: Pour over your the meat, veggies, or eggs you wanna stir fry or keep in a sealed jar in the fridge (see notes below). Remember, the sauce is gonna be on the saltier side so use sparingly - add a few teaspoons first and increase as needed.
Notes
You can simmer if you want to: This sauce is a thinner texture since we aren't simmering it. Usually a lot of stir fry sauces would include water, brown sugar, and sometimes a cornstarch slurry to thicken the texture while simmering. You can do this here too! Switch the honey for brown sugar, add about a 1/4 cup water total instead of 2 tbsp and add 2-3 tsp of cornstarch. Simmer for 5 minutes until the sauce thickens into a maple syrup consistency. (It will thicken further when cooled). This will give you a thicker more restaurant-style or bottled sauce consistency. Otherwise, the texture of this sauce is meant to be lightly splashed over your veggies the same way you would with soy sauce, or soaked in as a marinade for tofu or meats!
Toast your sesame seeds lightly in a dry pan (30 seconds) before mixing if they’re raw — it improves aroma. Or, buy pre-toasted sesame seeds.
Storage: Keeps in the fridge 5–7 days in a sealed container.
Substitutions: Swap honey for sugar or maple syrup (1:1), soy sauce for tamari (for gluten-free), adjust or omit sriracha.
Reheating tip: If sauce thickens in the fridge, warm slightly or stir in a teaspoon of water before using.
Batching tip: I often double or triple the batch and keep on hand — makes weeknight stir fries truly five minutes.
