Ingredients You’ll Need
The beauty of this recipe is its fuss-free lineup of ingredients: each vegetable brings its own character, while the delicious sauce creates harmony and depth. Here’s what you’ll need, along with some personal tips to make every element shine.
- Vegetable oil: Perfect for high-heat stir-frying; choose a neutral oil like canola or sunflower for best results.
- Zucchini: Adds a tender, mild flavor and absorbs the sauce beautifully—slice into half moons for quicker cooking.
- Yellow squash: Balances out the earthiness of the mushrooms with its gentle sweetness and bright color.
- Mushrooms (shiitake or button): Earthy and meaty; shiitakes add more umami, but button mushrooms work great too.
- Onion: Sliced onions caramelize slightly, offering natural sweetness and a subtle crunch.
- Red bell pepper: Its vibrant color and gentle bite really pop in this dish; julienne for quick, even cooking.
- Green onions: Cut into 2-inch pieces for bursts of fresh, herbal flavor layered throughout the stir-fry.
- Garlic: No stir-fry is complete without a punch of garlic—mince finely so it infuses the oil, not burns.
- Fresh ginger: Provides warmth and brightness; grate or mince to maximize its flavor release.
- Oyster sauce: This key ingredient creates depth and that classic savory-sweet character—don’t skip it!
- Soy sauce: Basic soy is crucial for saltiness and rich color; you can swap with tamari for a gluten-free version.
- Dark soy sauce: Delivers a gorgeous deep color and a bit more molasses-y richness to the sauce.
- Chili paste or sauce: Adds the perfect kick—adjust to suit your heat level!
- Sesame oil: Just a drizzle transforms the entire dish with its toasty, nutty aroma.
- Sugar: Balances out the salt, heat, and umami for a smooth, rounded finish.
- Water: Loosens the sauce and helps everything meld together.
- Cornstarch mixed with 1 tbsp water (optional for thicker sauce): This simple slurry transforms your sauce into a glossy, clinging coating that makes every vegetable irresistible.
How to Make tbsp water (optional for thicker sauce)
Step 1: Prep All Your Ingredients
The stir-fry world moves fast, so it’s essential to have everything ready before the wok heats up. Slice your zucchini and yellow squash into half moons, mushrooms and onions into strips, red bell pepper into thin julienne, and cut the green onions to 2-inch lengths. Mince that garlic and ginger until you can practically smell the flavor coming alive. This mise-en-place makes the entire process smooth and incredibly satisfying!
Step 2: Fire Up the Wok
Set your wok (or a large skillet if you don’t have one) over medium-high heat and add the vegetable oil. Give it a few moments to shimmer—when the oil is hot, toss in the garlic and ginger. Let them sauté for just about 30 seconds; you’re looking for their fragrant burst, not browned bits. They’ll infuse the oil, giving your veggies a tasty head start.
Step 3: Toss in the Veggies
Add onions, mushrooms, zucchini, yellow squash, and bell peppers all at once for a colorful veggie chorus. Stir-fry them for 3 to 4 minutes, keeping things moving so nothing sticks or steams. The goal is to get them just tender-crisp—they should still have bounce when you bite in. Add the green onions for the last minute and enjoy that extra hit of garden-fresh flavor.
Step 4: Whisk Together the Sauce with tbsp water (optional for thicker sauce)
While your veggies are sizzling, quickly whisk together oyster sauce, soy sauce, dark soy sauce, chili paste, sesame oil, sugar, and the water in a small bowl. If you’re seeking a thicker, glossier sauce, whisk in the cornstarch with 1 tbsp water (optional for thicker sauce). Everything comes together fast, so having this ready is key.
Step 5: Combine and Finish
Pour your sauce over the hot veggies in the wok. Toss everything together so every piece is cloaked in that savory, spicy, slightly sweet glaze. If you opted for the cornstarch slurry, add it now and let the sauce bubble for another minute until it thickens fabulously. Serve the veggies hot and steamy straight from the pan—tbsp water (optional for thicker sauce) can truly make the sauce cling perfectly to each bite.

Garnishes
Fresh garnishes make the difference between a good stir-fry and a memorable one. Try a sprinkle of toasted sesame seeds for crunch and nutty aroma, a scattering of sliced green onions for a pop of herbal sharpness, or a quick squeeze of lime for unexpected brightness. The sauce thickened with a little tbsp water (optional for thicker sauce) means the garnishes stay put and look beautiful.
Side Dishes
This stir-fried vegetable medley is just perfect with steamed jasmine rice or fluffy brown rice, allowing you to savor every bit of sauce. If you’re after something different, serve alongside noodles or as a topping for crispy tofu. The lush sauce made with tbsp water (optional for thicker sauce) means nothing gets lost—every grain or noodle is flavor-packed.
Creative Ways to Present
You can transform the presentation by serving the stir-fry over golden fried rice, pile it into lettuce cups for a fun appetizer, or spoon atop a rice bowl with a runny fried egg. The glossy finish from the tbsp water (optional for thicker sauce) makes each creative presentation pop on the plate and draws lots of “wows” at the table.
Make Ahead and Storage
Storing Leftovers
Let your leftover veggies cool completely before popping them in an airtight container. They’ll keep happily in the fridge for up to 3 days. The sauce, made thicker with tbsp water (optional for thicker sauce), keeps the veggies from turning soggy and helps maintain that signature texture and zip.
Freezing
If you want to freeze these veggies, let them cool first. Store them in a freezer-safe zip bag or container—you may lose a bit of the stir-fry’s crispness, but it’s still delicious reheated, especially with the sauce’s shine from tbsp water (optional for thicker sauce). Use within one month for best results.
Reheating
For beautifully revived leftovers, toss the veggies back in a hot skillet or wok over medium heat with a splash of water to re-steam. Stir gently so the glossy sauce with tbsp water (optional for thicker sauce) comes back to life—microwaving works too, but you’ll get a fresher flavor on the stovetop.
FAQs
Can I use other vegetables?
Absolutely! Bok choy, snow peas, carrots, broccoli, or even baby corn all play well in this stir-fry. Just adjust the cooking time to keep everything crisp and vibrant.

That handy slurry of cornstarch and tbsp water (optional for thicker sauce) gives your sauce the luscious, restaurant-style body that hugs each veggie. Skip it for a lighter, runnier sauce, or add it for extra cling and gloss—chef’s choice!
