Glass and ceramic bowls are usually microwave-safe. Never put metal or aluminum bowls or dishes in the microwave. You can use wax or parchment paper instead of plastic wrap.
To adjust the power level, enter the cook time first and then press the “Power” button. The reduced power will allow your soup to defrost evenly. If you are heating with glass or ceramic, the container may be hot. Use an oven mitt or heat-resistant glove to remove from the microwave.
Don’t make contact with the bottom or sides of the bowl, this will give an incorrect temperature reading. If you don’t have a thermometer on hand, you can use a knife. Insert the knife into the center of the bowl. The soup is warm enough to eat when the knife is hot when removed.
Soup stored in a glass may need extra time to defrost to make it easier to remove. If stored in a bag, let the soup sit in the sink until you can squeeze the bag and the soup breaks into pieces.
It’s best to add water to the pot because soup absorbs water when it’s frozen. This is also a great time to add additional seasonings to give the soup a fresh flavor. Try adding a little lemon juice, a pinch of salt, and fresh herbs. [3] X Research source
A thick-bottomed pot works best for heating soup because it evenly distributes heat. If you happen to burn the soup, do not scrape the bottom. Instead, pour the soup into a different pot and reheat.
