Cucumbers and zucchinis look like very similar vegetables, with a long shape, green skin, and whitish innards. However, these two veggies are not as similar as you may think; for starters, a zucchini has a thick, wood stem and white innards, while cucumbers have larger seeds and more of a pale green interior.

In terms of flavor and texture, cucumbers are crisp, juicy, and usually eaten raw or pickled, while zucchinis have a more bitter taste, but can be eaten raw or cooked. Also, cucumbers should be stored at room temperature to avoid premature rotting, while unwashed zukes do well for up to five days in the fridge.

Another difference is that the serving size for a cucumber is half a cup, while the zucchini's is a full cup, according to FoodStruct. Now that you know the differences between these veggies, remember that they can't replace each other in every recipe, especially ones that involve cooking with heat.
