If you’ve bought fresh vegetables, then they won’t need to be frozen and are ready to be washed.

If you’ve thawed frozen, packaged vegetables, they won’t need to be washed. Frozen vegetables are cleaned and cut before they’re packaged.

If you’re steaming multiple types of vegetables—e. g. broccoli, Brussels sprouts, carrots, and asparagus—try to cut them all so they’re roughly the same size.

If you have more vegetables than can be spread in a single layer, plan to steam them in separate batches.

Thin, leafy veggies like spinach will barely need any water added. Start with 1 tsp (5 mL). Thicker veggies like carrots will need a more substantial layer of water.

If you’d prefer not to microwave plastic wrap, you could substitute a large porcelain, stoneware, or ceramic plate. [4] X Research source

The amount of time needed to fully steam vegetables will vary based on the number of veggies you’re steaming and the thickness or density of the individual vegetable pieces.

Repeat this process until all of the veggies are fully steamed.

Or, if you’re planning to incorporate the steamed veggies into a dish, you can begin preparation on that item now.
