Recipe developer Annabelle Randles combines cauliflower and sharp cheddar cheese to create a creamy and velvety soup that she likes to serve with croutons and fresh thyme.

Can I use frozen cauliflower instead of fresh?

You can use frozen cauliflower instead of fresh in this cheesy cauliflower cheddar soup. You might find it more convenient to use frozen cauliflower, especially when fresh cauliflower is not readily available or if you want to save time on preparation. Using frozen vegetables to make soup actually sometimes yields better results, especially when you want to enjoy vegetables that are out of season. While fresh vegetables are often transported over long distances and left to sit on shelves, frozen vegetables are generally picked when fully ripe and frozen straightaway to preserve their nutritional value. In addition, frozen cauliflower often works out to be cheaper than fresh cauliflower.

Using frozen cauliflower for this recipe calls for a very straightforward swap. Simply add the frozen cauliflower with the potato and stock. You don't need to thaw it first but keep in mind that frozen cauliflower might give the soup a slightly different consistency as it will release more moisture into the soup, so you can adjust the amount of liquid you add accordingly. The soup will also take slightly longer to cook. 

Can I make this soup ahead of time?

You can make the soup ahead of time and store it to enjoy later. Allow it to cool completely before transferring it to an airtight container, at which point you can either freeze the soup in single servings, freeze it in bulk, or refrigerate it. 

To thaw it from frozen, transfer the soup from the freezer to the refrigerator and let it sit overnight. Once thawed, reheat the soup on the stovetop or in the microwave, stirring occasionally. You may need to adjust the consistency by adding a little extra stock or water. For the best results, try to consume frozen cauliflower soup within 2-3 months. So you can keep track of how long the soup has been in the freezer, remember to clearly label the containers with the name of the soup and the date of preparation.

To reheat from refrigerated, warm up the soup on the stove over low heat, stirring occasionally. For the best flavor, try to consume refrigerated cauliflower soup within 2-3 days.
