Ingredients

1 medium zucchini, sliced into ¼″ rounds or half-moons

1 red bell pepper, sliced into ⅛″ strips
1 yellow or orange bell pepper, sliced into ⅛″ strips
1 large carrot, peeled and julienned into thin sticks

1 small red onion, peeled and cut into thin wedges
100 g (about 3½ oz) mushrooms, wiped clean and thinly sliced
3 cloves garlic, minced finely

2 tbsp vegetable oil
½ tsp red chili flakes (adjust to taste)
2 tbsp oyster sauce

1 tbsp soy sauce (light or reduced-sodium)
2 green onions, chopped for garnish
Optional: steamed rice or cooked noodles, to serve

Step-by-Step Cooking Directions

Prep the Vegetables: Wash and cut zucchini into even rounds or half-moons. Slice bell peppers into long, thin strips. Peel and julienne the carrot. Slice the red onion into uniform wedges. Wipe mushrooms with a damp cloth and slice thinly. Mince the garlic.
Heat the Pan: Place a large skillet or wok over high heat. When the surface is smoking slightly, add the vegetable oil and swirl to coat.
Sauté Aromatics: Add minced garlic and red chili flakes. Stir for 30–45 seconds, just until garlic is fragrant and beginning to turn golden—avoid browning.

Cook Harder Vegetables: Add red onion and carrot. Stir-fry for 2–3 minutes, tossing constantly, until edges begin to soften.
Add Bell Peppers and Zucchini: Toss in bell pepper strips and zucchini. Continue to stir-fry for 4–5 minutes, ensuring high heat is maintained. Vegetables should be brightly colored and slightly crisp.
Finish with Mushrooms: Add sliced mushrooms and stir-fry for 2–3 minutes until tender and any released juices evaporate.

Season the Stir-Fry: Pour oyster sauce and soy sauce over vegetables. Toss thoroughly to coat every piece. Stir-fry for an additional 1–2 minutes to allow flavors to meld.
Garnish and Serve: Turn off the heat. Sprinkle chopped green onions over the stir-fry. Serve immediately as a side dish or spoon over steamed rice or noodles for a complete meal.

The Origins and Popularity of the Recipe

Stir-frying is a classic Chinese cooking technique dating back thousands of years, prized for its speed and ability to preserve color, flavor, and nutrients. The method spread across East Asia and eventually became a global favorite for quick, healthy meals. Oyster sauce, invented in 1888 by Lee Kum Sheung in Guangdong Province, adds depth and umami. Today, vegetable stir-fries are ubiquitous, appearing in home kitchens and restaurant menus worldwide. Their adaptability—mixing seasonal produce, proteins, and sauces—ensures continual reinvention and enduring popularity.

Common Mistakes to Avoid

Overcrowding the Pan: Crowded pan lowers heat, causing vegetables to steam instead of stir-fry. Cook in batches if necessary.

Incorrect Heat Level: Too low heat yields soggy veggies; too high burns garlic. Aim for high, but control flame.
Uneven Cutting: Different sizes cook at different rates. Slice evenly for uniform doneness.
Skipping Sauce Timing: Adding sauce too early dilutes it; wait until vegetables are nearly done.

Not Drying Mushrooms: Wet mushrooms release excess liquid, leading to sogginess. Wipe, don’t rinse, if possible.

Pairing Recommendations

Wine: A crisp Riesling or dry Gewürztraminer balances the dish’s savory-sweet notes.
Beer: A light lager or wheat beer complements without overpowering.

Non-Alcoholic: Sparkling water with lemon or iced green tea refreshes the palate.
Sides: Steamed dumplings, miso soup, or a side of kimchi for a broader Asian spread.

Cooking Tips

Prep First: Have all vegetables cut and sauces measured before heating the pan—stir-frying moves quickly.

High-Smoke-Point Oil: Use peanut or canola oil to withstand high heat without burning.
Layer Flavors: Start with aromatics, then add vegetables in order of cooking time.
Control Moisture: Squeeze zucchini dry if excessively wet; avoid rinsing mushrooms under running water.

Rest Before Serving: Let the stir-fry rest for a minute off heat so sauce thickens slightly.

Invented in Guangdong Province in the late 19th century, oyster sauce is a thick, dark condiment made by simmering oyster extracts with sugar and salt. Its deep umami flavor enhances stir-fries, marinades, and dipping sauces.
