• Soy sauce – Adds a savory, umami flavor; low-sodium versions are available for a healthier option.
• Sesame oil – A little goes a long way in providing that signature nutty taste; use toasted sesame oil for more depth.
• Zucchinis – Fresh, medium zucchinis bring a lovely texture; look for firm, glossy skins for the best quality.

Step‑by‑Step Instructions for Japanese Zucchini & Onion Stir-Fry

Step 1: Heat the Oil
Begin by heating 2 tablespoons of vegetable oil in a large skillet or wok over medium heat. Allow the oil to warm for about 2 minutes until it shimmers slightly, signaling that it’s ready for cooking. This step is crucial as it helps to evenly cook the vegetables later, ensuring they maintain their vibrant colors and flavors.

Step 2: Prepare the Vegetables
While the oil heats, wash and slice 2 medium zucchinis and 1 medium onion into thin, even pieces. Aim for slices about ¼ inch thick for uniform cooking. The vibrant greens of the zucchini and the translucent whites of the onion will brighten your kitchen, setting the stage for a delightful Japanese Zucchini & Onion Stir-Fry.

Step 3: Sauté the Onions
Once the oil is hot, carefully add the sliced onion to the skillet. Sauté for 2-3 minutes, stirring frequently until the onion becomes fragrant and starts to turn translucent. This initial step develops a sweet and savory base for the stir-fry, enhancing the overall depth of flavor.

Step 4: Add the Zucchini
Next, add the zucchini slices to the pan, stirring them in with the sautéed onions. Continue to cook, stirring occasionally for about 5-7 minutes. The zucchini should become tender yet still maintain a slight crunch, providing a delightful textural contrast to the dish as it develops beautifully in color.

Step 5: Season the Stir-Fry
Stir in 2 teaspoons of soy sauce and 1 teaspoon of sesame oil, ensuring even distribution across the vegetables. This seasoning should be added during the last couple of minutes of cooking, allowing the flavors to meld without losing freshness. Adjust salt and pepper to taste, enhancing the savory notes that characterize this Japanese Zucchini & Onion Stir-Fry.

Step 6: Serve Warm
Once the vegetables are cooked to your liking, remove the pan from heat. Transfer the stir-fry to a serving dish, allowing the warm, colorful blend to shine. This dish can be enjoyed on its own or paired with steamed rice, noodles, or quinoa for a more filling meal, capturing the essence of healthy eating.
