It’s like comfort food made fresh and light, the way dinner should be.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients that come together to create bold flavor and a satisfying texture without fuss or fancy additions. Here’s what you’ll need:

Zucchini (2 medium, sliced into half-moons) – fresh and firm for the best texture.
Cremini mushrooms (8 ounces / 225 grams, cleaned and sliced) – or baby bella mushrooms for that deep, earthy taste.
Yellow or white onion (1 medium, thinly sliced) – caramelizes beautifully and adds sweetness.
Garlic cloves (3 minced) – brings aromatic depth to the stir fry.
Extra virgin olive oil (2 tablespoons) – I prefer this for its fruity notes and health benefits, but avocado oil works well too.
Low sodium soy sauce or tamari (2 tablespoons) – adds umami without overpowering.
Freshly ground black pepper (to taste) – balances the flavors.
Red pepper flakes (optional, pinch) – for a little heat if you like.
Fresh herbs like parsley or basil (a small handful, chopped) – toss in at the end for brightness.

For those who want to customize, you can swap out the mushrooms for shiitake or portobello, or even add a splash of rice vinegar or lemon juice at the end to brighten things up. I usually keep it simple, but feel free to experiment with what you have on hand!

Equipment Needed

Large non-stick skillet or wok: A wide pan helps cook the veggies evenly and gives you enough space to toss everything without overcrowding.
Sharp chef’s knife: Essential for slicing zucchini, mushrooms, and onions thinly and evenly.
Cutting board: A sturdy surface for prep work.
Wooden spoon or spatula: For stirring and scraping the pan without scratching.

If you don’t have a wok, no worries — a large frying pan works just as well. I once tried this recipe with a cast iron skillet, and while it gave a nice sear, the non-stick pan made cleanup easier (and I’m all about that on a weeknight!). For budget-friendly options, you can often find decent non-stick pans at local stores or online without breaking the bank.

Preparation Method

Prep your veggies: Wash and slice 2 medium zucchinis into half-moons about ¼ inch (6 mm) thick. Clean and slice 8 ounces (225 g) of cremini mushrooms thinly. Peel and thinly slice 1 medium yellow onion. Mince 3 cloves of garlic. This step should take about 10 minutes if you work efficiently.
Heat your pan: Place your large skillet or wok over medium-high heat. Add 2 tablespoons of extra virgin olive oil and let it warm until shimmering but not smoking, about 1-2 minutes.
Sauté onions and garlic: Add the sliced onions and minced garlic to the hot oil. Stir frequently for 3-4 minutes until onions become translucent and just start to caramelize. Be careful not to burn the garlic — it should smell fragrant but not bitter.
Add mushrooms: Toss in the sliced mushrooms and cook for another 5 minutes, stirring occasionally. You want the mushrooms to release their moisture and begin browning. This step adds a lot of flavor — the smell will be amazing!
Cook the zucchini: Add the zucchini slices to the pan. Stir and cook for 4-5 minutes until tender but still slightly firm — you want that satisfying bite, not mushy.
Season: Pour in 2 tablespoons of low sodium soy sauce or tamari, sprinkle with freshly ground black pepper and a pinch of red pepper flakes if you like a bit of heat. Stir well to combine and cook for an additional 1-2 minutes so the flavors meld.
Finish and serve: Remove the pan from heat, toss in a handful of chopped fresh herbs like parsley or basil for a pop of color and freshness. Give it one last stir and it’s ready to plate.

If you notice the veggies sticking, you might need a splash more oil or lower the heat slightly next time. The key is to cook over medium-high heat but keep stirring so nothing burns. This method keeps your veggies vibrant and full of flavor.

Cooking Tips & Techniques

One of the best tricks I’ve learned with stir frying zucchini, mushrooms, and onions is to keep the heat hot but controlled. Too high, and the garlic burns; too low, and the veggies steam instead of sauté. Patience here goes a long way.

Another tip: slice your veggies uniformly. It sounds obvious, but uneven pieces can lead to some being undercooked while others turn to mush. I like to use a sharp knife and take my time — it makes a difference you can taste.

Don’t overcrowd the pan! If your skillet is too crowded, the veggies will release water and steam instead of getting that nice golden color. If needed, cook in batches or use the largest pan you have.

Also, add the soy sauce near the end to prevent it from burning and becoming bitter. A splash of liquid at the right moment helps deglaze the pan and lift all those tasty browned bits.

Lastly, I’ve found that tossing in fresh herbs right after removing from heat brightens the dish and adds a fresh aroma that’s irresistible. Try it—you’ll thank me later!

Variations & Adaptations

Feel free to mix things up based on your preferences or what’s in your fridge. Here are a few ideas:

Protein boost: Add cooked chicken strips, shrimp, or tofu to make it a complete meal. Toss them in during the last few minutes of cooking.
Spicy twist: Swap red pepper flakes for fresh sliced chili or a drizzle of sriracha for more heat.
Different veggies: Swap zucchini for yellow squash or add bell peppers and snap peas for a colorful stir fry.
Gluten-free option: Use tamari instead of soy sauce to keep it gluten-free and just as tasty.
Garlic lovers: Double the garlic for a punchier flavor — it pairs wonderfully with mushrooms.

One personal favorite is adding a splash of toasted sesame oil at the end for a nutty aroma that’s out of this world. It’s a small touch but really makes the dish special.

Serving & Storage Suggestions

This healthy low carb stir fry zucchini mushrooms onions recipe is best served hot, straight from the pan. I like to plate it alongside some steamed cauliflower rice or even spoon it over a bed of leafy greens for an extra veggie boost.

It pairs well with grilled chicken or fish if you want to add protein without much fuss. For drinks, a crisp white wine or a light iced tea complements the flavors nicely.

To store leftovers, transfer the stir fry to an airtight container and refrigerate for up to 3 days. When reheating, warm gently in a pan over medium heat or microwave in short bursts to avoid sogginess. The flavors actually deepen after a day or two, so leftovers can be a nice treat.

Nutritional Information & Benefits

Each serving of this stir fry is low in carbs (approximately 8-10 grams net carbs per serving), making it perfect for low carb or keto-friendly diets. Zucchini is rich in vitamins A and C, plus it’s hydrating and low-calorie. Mushrooms add important antioxidants and vitamin D, while onions provide prebiotic fiber to support digestion.

Using extra virgin olive oil adds heart-healthy fats, and the minimal soy sauce keeps sodium in check when using low sodium varieties. Overall, this dish is nutrient-dense, filling, and supports a balanced diet without any guilt.
