Or you can serve it over rice for a delicious vegetarian meal.

We always have so many zucchini during the summer months. I’m constantly trying different ways to cook with them and I think this is my favorite. It is so easy and the cooking time is just minutes. Even my kids love this dish. I can make a huge pan full and it disappears in a hurry.

Japanese Zucchini Recipe Tips:

You can add a pat of butter to the pan at the end for extra flavor and a little richness.

The soy sauce and teriyaki sauce add a nice saltiness. Use low-sodium soy sauce if you need to keep the salt level down.

You can easily change this recipe up to suit your tastes and use up the ingredients you have on hand. Mushrooms are a great addition as is a little garlic. Some broccoli would be great added to the pan as well. You can also experiment with how big or small you want your zucchini pieces.

Cook just briefly if you want the zucchini to still have some crunch or longer if you want it completely soft.

Sometime we like to add a little store-bought Yum Yum Sauce when we serve it. A drizzle of sesame oil is also good. You can add a little Sriracha sauce or chili garlic sauce if you want it spicier.

  1. I left out the red pepper flakes, as we don’t like spicy hot dishes.
    I added some pre-cooked diced turkey into the teriyaki/soy stir fry. And then at the very end 1 minute, added the butter and some halved grape tomatoes (so they wouldn’t get mushy).
    Then plated each serving over cooked white rice.

    This was a big hit at our dinner table!

  2. Turned nicely. Zucchini kept its bright green color and sauce gave that nice potsticker dipping sauce flavor!! Loved it

  3. This is definitely delicious! I love adding it to rice bowls with chicken, kale, mushrooms, broccoli and lots of yum yum sauce!!!

  4. Great to find a recipe for bountiful summer squash. I made this as a side for garlic-honey shrimp. Outstanding flavor.

  5. I’ve have made this recipe several times. So easy to make. I have tweaked it a bit. Instead of the soy sauce I use Sweet Baby Ray’s [Teriyaki sauce. Also add in a bit more red pepper flakes. You can add in as much or as little as you like. If you LOVE zucchini. You will love this easy recipe. Thank you for the recipe.

  6. This looks so good, however, I’m wondering just how spicy it is. I don’t do well with spicy foods so a little nervous to try it.

    1. Make sure you use a sweet onion and leave off the pepper flakes. It won’t have any heat but still taste good.

    2. You can add in a little red pepper flakes. I’m not a spicy person. But I did add more for me. This recipe is delicious.
