If you’re working with long vegetables, such as carrots or celery, chop them up first to get a more accurate estimation.

Avoid smashing your vegetables when you pack them down, or else you might have an inaccurate measurement. Even though a standard measuring cup is equivalent to 8 ounces (230 g), vegetables have different densities so they may weigh more or less than that. Avoid assuming that 8 ounces (230 g) of a veggie is the same as 1 cup. [3] X Research source

If you’re working with cooked leafy vegetables, then you only need to fill your measuring cup once.

You don’t need to rehydrate vegetables before using them if you’re using a recipe that you need to cook. Otherwise, simmer the vegetables in water for 10–15 minutes or let them soak for 1–2 hours. [6] X Research source

Vegetables make great side dishes, but they’re also so easy to incorporate into your recipes. For example, you can add fresh vegetables to pasta sauces or sandwiches.

About 16 cherry tomatoes will also give you enough for a cup. [12] X Research source
