Common Mistakes to Avoid
When making Japanese Zucchini, it’s easy to overlook a few important details. Here are common mistakes to watch out for:
-
Skipping the prep: Not cutting the zucchini properly can lead to uneven cooking. Always cut your zucchini into uniform pieces for consistent results.

Overcrowding the pan: Adding too much zucchini at once can cause steaming instead of sautéing. Cook in batches if necessary to achieve a nice sear.
-
Neglecting seasoning: Forgetting to add enough soy sauce or teriyaki sauce can leave your dish bland. Taste as you go and adjust seasoning accordingly.
-
Not controlling the heat: Cooking on too high heat can burn the vegetables. Medium-high is ideal for achieving that perfect tender-crisp texture.
-
Ignoring garnishes: Skipping sesame seeds means missing out on added flavor and texture. Don’t forget this simple finishing touch!
