Question: how many cups does 1 medium zucchini make?
Answer: When sliced, 1 medium zucchini yielded about 1 to 1.25 cups and if grated, you end up with about 2/3 cup of tamped down zucchini. If you need 1 cup of cooked sliced zucchini, due to shrinkage while heated it will take about 3 medium zucchini, sliced, to hit the mark.
