How to make frozen vegetable soup

Step 2: Cook for 5 minutes to allow the veggies to defrost and start cooking.

Step 3: After cooking for 5 minutes over medium heat, add the rest of the soup ingredients (vegetable broth, canned tomatoes, balsamic vinegar and herbs and spices).

Step 4: Cover the pot and allow to cook over medium low heat for 20 minutes until the veggies are tender fully cooked.

Tips on making the best vegetable soup from frozen veggies

One of my top tips on how to make a tomato based soup or sauce taste like it’s been cooking all day is to add balsamic vinegar! It cuts through that canned tomato taste like nothing else I’ve tried!

Another great way to add lots of flavor quickly to a dish is to use vegetable stock or vegetable broth. It instantly imparts so much flavor into a dish; so be sure not to skip this ingredient.
