Defrost your frozen veggies in the refrigerator before cooking them. While you can definitely cook with frozen veggies, experts often recommend thawing them out beforehand, so they don’t lower the temperature of your dishes during the cooking process. You can leave certain frozen veggies, like bagged corn and peas, on the counter for a few minutes instead of defrosting them overnight.^{[5]

- It’s not a good idea to add completely frozen foods to dishes like stews or soups, since they’ll lower the temperature of the dish. Then, you may overcook the food while you wait for the temperature to rise again.
- You can simply rinse bags of frozen peas and corn under cold water instead of thawing them overnight.
- Always thaw and wring out frozen spinach before you add it to any dishes.^{[6]

Convert your vegetables from cups to ounces as needed. Vegetables come in all shapes and sizes, so there isn’t a one-size-fits-all measurement that applies to them all. Instead, convert vegetables individually for an exact measurement.^{[7]

Tips

Be careful not to use a weight listed as "cooked from frozen" as how much a vegetable weighs when frozen. "Cooked from frozen" means it was frozen but then was weighed after it was cooked.
