Frozen vegetables often get a bad wrap, with people thinking they lack as much nutritional value as fresh veggies. Although freezing some vegetables can cause some slight reduction in nutrient density, according to Healthline, a lot of the nutrients in frozen veggies are usually preserved. You will still get almost all of the vitamins, minerals, and other nutrients offered by your favorite veggies even when said veggies come from a bag in the freezer aisle. (Or when you freeze them yourself.)
Healthline also states the obvious greatest benefit of cooking with frozen vegetables: that they are super convenient and simple to cook. Instead of going to the store or farmers market in search of fresh, in-season produce, simply go to your freezer for the vegetables you need to prepare this healthy soup.
