Common Mistakes to Avoid
Sauteing Japanese Zucchini can be simple, but there are some common pitfalls to watch out for.
- Overcooking the zucchini – Cooking zucchini for too long can make it mushy. Aim for a tender yet crisp texture by checking doneness after 4-5 minutes.
- Skipping the seasoning – Failing to add enough seasoning can lead to bland flavors. Use soy sauce and teriyaki sauce generously for a burst of taste.
- Not cutting uniformly – Unevenly cut zucchini pieces cook at different rates. Cut all pieces to the same size for even cooking.
- Ignoring oil temperature – Adding vegetables to oil that isn’t hot enough can result in soggy zucchini. Heat the oil adequately before adding your ingredients.
- Forgetting about garnishes – Skipping sesame seeds or not using them at the end diminishes flavor and presentation. Always remember this final touch.
