Why the Homemade Version Is Better

Homemade v.s. Store-Bought Oyster Sauce

Oyster sauce is probably the only Chinese stir-fry sauce that I consider a must-have for any Chinese and Asian food lovers. I, however, stop using it a few years ago because the ingredients, sadly, in today’s fast food/mass productions, aren’t that great for our bodies.

I took photos from my recent trip to a local grocery store. One photo is for “oyster-flavored” oyster sauce and the other is called Vegetarian mushroom-flavored stir-fry sauce (AKA Vegetarian oyster sauce).

As you can see from the photos that the first ingredient is water and followed by sugar and other colorings, starch, and artificial flavorings. In my opinion, occasional consumption is okay because we all have to eat out (unless you have specific medical reasons or are allergic to the ingredients) but if I’m making the meals at home, which is most of the time, I recommend making the sauce by ourselves.

You’ll be amazed how fresh and flavorful the sauce tastes and you know exactly what goes into it. The flavor is so vivid and umami-rich and it’ll become one of your top go-to Paleo stir-fry sauces!

How to make vegetarian oyster sauce at home in 15-minutes!

I use dried shiitake mushrooms as the base of my vegetarian oyster sauce because dry shiitake contains a more concentrated umami flavor than fresh ones. I also use the mushroom water that’s from soaking the mushrooms overnight as my liquid base.

  1. Lightly sauteing the mushrooms with fresh ginger will remove the “raw” flavor and bring out a more umami aroma.
  2. Simply blend everything in a high-speed blender and you’ll have a perfectly healthy and delicious Mushroom Oyster Sauce!

How to convert store-bought oyster sauce to the homemade version

Add your homemade mushroom oyster sauce to any Paleo stir-fry dishes you love. Since the homemade version is less salty than the store-bought bottles, when you try to convert a recipe you find on the internet, use a bit more.

For example, if a regular recipe calls for 1 teaspoon or 2 teaspoons of (store-bought) oyster sauce, substitute it with 1 tablespoon of our homemade vegetarian oyster sauce.

Add the sauce to Chinese Broccoli Stir-Fry, Chinese Mustard Green Stir-Fry, Shiitake mushroom with baby bok choy stir-fry, or beef stir-fry in oyster sauce!

Vegetarian oyster sauce recipe made with shiitake mushrooms is the best Paleo stir-fry sauce for vegan and gluten-free people.

Is there a vegetarian substitute for oyster sauce?

Yes. My vegetarian oyster sauce is also vegan, gluten-free, Paleo, Keto, and Whole30. The vegetarian substitute oyster sauce is made with shiitake mushrooms, fresh ginger root, salt, coconut aminos, mushroom water, and dates. The ingredients are completely vegan and easy to make.

Recipes you can make with the sauce

Try the sauce with Stir-fried beef in oyster sauce, Oyster sauce chicken stir fry, Chinese broccoli with vegetarian oyster sauce, Vietnamese garlic shrimp, and Thai crispy fried cauliflower rice! Or drizzle it over steamed bok choy. The possibilities are endless.

Ingredients  

Vegetarian Oyster Sauce Ingredients

Instructions 

  • Soak the dried shiitake mushrooms with 4 cups room temperature water overnight. The mushrooms will rehydrate and become soft and juicy.
  • Gently squeeze the mushrooms to remove the water. Thinly slice and set them aside.
  • In a bowl, filter the mushroom water through a sieve. Also finely chop ginger. Set them aside.
  • In a well-heated skillet, add avocado oil. Saute mushrooms with ginger and ¼ tsp salt over medium-high heat for about 4 minutes.
  • Add ½ tbsp coconut aminos and keep sauteing for another 1 minute. Off heat and set it aside to cool.
  • In a high speed blender, add 2 ¼ cups mushroom water, pitted dates, sautéed mushrooms and ginger, and the remaining salt and coconut aminos. Seal the lid tightly and blend on high for 60 seconds or until the mixture is very smooth. There should be no food chunks.
  • Store the mushroom oyster sauce in a sealed glass container in the fridge for up to 2 weeks.

Notes

To freeze: Store the sauce in ice cube trays in the freezer for up to 2 months. Defrost overnight in the fridge. There might be separation between the mushroom mixture and the liquid. Shake the bottle or stir and they will be back to life!

    I cut the recipe in half.
    It came out really nice and flavorful.
    Worked perfectly with the recipe I that I needed an oyster sauce. I will definitely keep this recipe for future use.

  2. Susan says:

    Can the coconut aminos be substituted for soy sauce?
    Thanks!

    1. ChihYu says:

      You will need to reduce the quantity as coconut aminos is less salty and naturally sweeter than soy sauce. You will also need to add a sweetener to balance the salty flavor in order to make the sauce tastes right.

  3. Susan says:

    Hi, how strong is the taste of the shiitake mushrooms in this recipe?
    Thanks

    1. ChihYu says:

      Hello Susan, it does have shiitake mushroom flavor and that’s the main flavor of this vegetarian vegan version. 🙂

  4. Maximilian says:

    Hello! Thanks for the recipe. Can I use soy sauce instead of coconut aminos?

    Best Regards,
    Maximilian

    1. ChihYu says:

      Hey Max, you can but with some tweaks – You’ll need to reduce the quantity because soy sauce is much saltier than coconut aminos. In general 2 tbsp coconut aminos = 1 tbsp soy sauce. And you will need to add some sugar (or increase the sugar content) in the recipe because coconut aminos tastes naturally sweeter than soy sauce.

    I’m on a low carb diet, so I omitted the dates. The sauce is beautiful – thick and glossy just like oyster sauce – and very flavorful. This recipe bit too salty for my taste, so I would recommend starting with half the salt and tasting til it’s right for your taste. This makes a lot of sauce. I froze the leftover in ice cube trays, so I can easily drop it into soups and stir fry recipes.

  6. Nicki says:

    Is the taste of the oyster sauce the same if you let the mushrooms soak for 24 hours compared to overnight?  I’ve never had oyster sauce and It has a strong earthy flavor. Is that normal? 
    Thank you ! 

    1. ChihYu says:

      Yes. shiitake mushroom has a strong woodsy flavor. The homemade version is less salty and less sweet, compared to the store bought version.

  7. nurp says:

    Can I use date syrup instead of dates?

    1. ChihYu says:

      Yes. Date syrup works, too! You might need to adjust the quantity. Taste and adjust! 🙂

  8. Jo Cranston says:

    Thank you for this, I love oyster sauce but am very allergic (as I found out to my cost on a first date once…)
    I’d never through to try mushrooms instead.

    1. ChihYu says:

      No problem!

    I’ve never had “real” oyster sauce to compare, BUT THIS IS DELICIOUS!!! Used liquid aminos instead of coconut, as THATS all I had.

    1. ChihYu says:

      Thank you, Em! I’ve never tasted liquid aminos ….I know it tastes different from coconut aminos because the ingredients are different but happy to hear you like it! 🙂

  10. Orna Feldman says:

    what can i use as a date substitute? prunes? raisins? dried cherries?  thank you

    1. ChihYu says:

      Hi Orna, I’d say prunes will be the closest substitute!
