Can zucchini and cucumber be stir-fried together?
Generally speaking, zucchini and cucumber can be stir-fried together. The detailed analysis is as follows:

Zucchini and cucumber can be stir-fried together because their textures are similar and their flavors complement each other. Zucchini has a soft, tender texture and a mild taste, while cucumber is crisp, juicy, and slightly fragrant. When stir-fried together, the combination of tenderness and crispness enhances the eating experience. Their mild flavors do not clash; on the contrary, they create a fresher overall taste, making this dish suitable for people who prefer light-flavored food. Additionally, both vegetables contain vitamins and dietary fiber, so consuming them together increases nutritional intake and helps meet the body’s needs for various nutrients.
When stir-frying zucchini and cucumber, it's important to control the heat and cooking time to avoid overcooking, which can make the vegetables mushy and cause them to lose their desirable texture. It's recommended to use high heat and quick stir-frying to maintain their crisp-tenderness. Moreover, since both ingredients have high water content, there's no need to add extra water during cooking, to prevent excessive liquid in the final dish. Seasoning should remain light—use less salt and sugar—to better highlight the natural freshness of the vegetables. Excessive seasoning may mask their original delicate flavors.
