These healthy and easy Sautéed Asian Zucchini and Onions take less than 15 minutes for an easy Whole30 and low carb side dish! They are perfect for busy weeknights.
I’ve been eating this Whole30 and gluten free zucchini side dish for years, but never posted a recipe for it. It’s something I came up with on my own one day without measuring anything, and both my husband and I loved it so much that we started making it almost twice a week as a side dish. Since I’ve been asked several times for the recipe after showing my dinner plates on Instagram Stories, I finally decided to share this easy pan fried zucchini recipe with you!

Sautéed Asian Zucchini and Onions
The reason I keep going back to this Whole30 zucchini recipe again and again is that not only is it super flavorful, it takes less than 15 minutes total to make! The sautéed zucchini and onions are coated in a delicious sauce of coconut aminos, fish sauce, and toasted sesame oil, and while it sounds simple, it’s incredibly addicting. I’ve actually eaten the whole batch on my own in one sitting, because I was enjoying it more than the main meat dish!
How to Cook Asian Zucchini and Onions So They Aren’t Mushy
One of my biggest pet peeves about cooked zucchini is when they are mushy. Because they have a high water content, it’s quite easy to overcook zucchini. I found that the way you cut zucchini affects the texture a lot in this easy pan fried zucchini recipe.
I’ve tried cutting them in rounds before, which is done often by home cooks, but I didn’t like how they turned out at all and it was actually difficult to get them to cook evenly this way. For best results, I found that slicing them into thicker sticks is the way to go:
- Do not peel the zucchini.
- Cut the zucchini into 3 even pieces widthwise.
- Take each third and quarter each piece LENGTHwise.
- Then, you take each quarter and halve it lengthwise.
You should be left with 8 zucchini sticks from each third of a zucchini, and a total of 24 pieces from one zucchini. Makes sense? Once they are cut, you are ready to make these easy and flavorful sautéed zucchini and onions!
Another method to creating a crispy and crunchy gluten free zucchini side dish is to add the onions in later. In most stir-fry recipes, onions are added in with the garlic at the beginning. However, in this Whole30 zucchini and onion side dish, you’ll want to add the sliced onions at the end so they aren’t cooked all the way through when you are serving it.
All the textures and flavors meld together so beautifully in these sautéed Asian zucchini and onions, and the sesame seeds added at the end creates a yummy crunch that’s just irresistible. Once you make this dish, I bet it’ll be something you make over and over again in the future when you need a quick and healthy side dish!

We cant really get coconut aminos in Europe (at least not easily). Any substitute for it?
You can use tamari or soy sauce (contains gluten), but reduce the salt if that’s what you are using.
New favorite side dish! So simple yet the flavors are just amazing! I have never cut zucchini this way, but it definitely does help the texture and prevent it from getting mushy. Thanks so much for sharing this, will definitely be making this weekly (or more!).
I love this recipe. Now that we have zucchini coming out of our garden I am cooking it like this weekly. Great with yellow squash too.
5 star, so delicious! I kade this once a week and eat it w rice. Thank you!
Sounds amazing. Thanks for leaving a review!!
I saw your post on Instagram and had to try this zucchini recipe. All I can say is DELISH!!
Thank you so much!
So delicious!
Thank you!!
So simple, so good! I followed her recipe exactly and it came out so well – zucchini was crisp-tender. I think the hero here is the way the coconut aminos and fish sauce make a yummy sauce. Highly recommend and right now – I really needed a new way to eat zucchini.
That’s amazing to hear! I’m obsessed with the sauce too.
So good, so fast, so easy- exactly what I’m looking for in a weeknight side dish. Thanks for making this the zucchini recipe we’ll make time and time again!
SOOOO happy that you enjoyed it!
I love zucchini and roast little coins in the oven all the time. But this simple, delicious recipe is a game changer! Subtle changes like cutting them in sticks and adding the onions later in the cooking process make this recipe a keeper. Thank you for sharing!
So glad you liked it. Thank you so much!
Absolutely delicious! Simple, quick, easy, this recipe is already a favorite. Thank you!
Thank you so much!!
It was a hit in our household!! I love the cutting method with detailed instructions. The method of cutting up the zucchini was genius and it keeps a nice texture. I have tried numerous times to sauté with zucchini sliced into rounds. Just a mushy mess.
This makes me so happy! Thank you for leaving a review.
This was fast, easy and super delicious! Even my husband ate it and he’s picky, picky…I am going to try this method with broccoli next!
Yay! Thank you so much!!
This recipe is easy and delicious. My husband and I both loved it. I doubled it and have plenty of leftovers.
Is there anything you can substitute for fish oil? I really hate a fishy taste.
Just soy sauce or coconut aminos will work!
