    In winter, I love nothing more than snuggling up on a comfy chair and wrapping my hands around a big bowl of warm soup.

    And of course, the only thing that makes a bowl of healthy, nutritious soup better, is a homemade roll, savoury muffin or scroll on the side for dipping!

    Ham and Cheese Scrolls, Ham, Cheese and Zucchini Muffins, Homemade Soft and Fluffy White Rolls and Cheese and Bacon Muffins served on the side are just a few of my favourites.

    For more serving suggestions, scroll down to the FAQ section!

    • cauliflower - there are many varieties of cauliflower, of which the most common is the white cauliflower.
    • broccoli - a healthy and versatile vegetable that can be used in everything from salads to quiches.
    • tasty or cheddar cheese 
    • bacon - although the bacon pieces are optional, I highly recommend that you add these crispy little bits of flavour when you serve the soup!

    Step By Step Instructions

    With very little prep required, this soup will be ready in just 40 minutes from start to finish!

    Note: Scroll to the recipe card at the bottom for the ingredients, quantities and full detailed method.

    Step 1: Sauté

    Melt the butter in a large pot on the stove.

    Then, add the chopped onion, minced garlic and chopped carrots.

    Sauté for 5 minutes, until the onion is translucent and the carrots start to soften.

    Expert Tips

    Can I use frozen broccoli and cauliflower?

    Frozen broccoli and cauliflower can be substituted. Use 4 cups of frozen, chopped broccoli and cauliflower to replace the fresh vegetables. It is best to defrost the vegetables in a colander to drain the excess liquid first.

    What is the best way to freeze Broccoli and Cauliflower soup?

    Simply allow the soup to cool completely and then freeze in airtight containers for up to 3 months. Defrost and reheat in the microwave or on the stove-top.

    How long do I need to cool the soup before puréeing it?

    Leaving the soup uncovered for about 5 minutes will cool it enough to safely purée or blend it. If you skip this step, there is a risk that the steam from the hot soup will build pressure in the food processor or blender. This will cause the lid to come off and could result in burns.

    What can I serve with the soup to make it into a main meal?

    Some serving suggestions are:
    * Crusty white bread rolls
    * Sourdough bread, rubbed with a garlic clove, and lightly brushed with olive oil before being toasted
    * Savoury Muffins
    * Pizza Scrolls or Ham and Cheese Scrolls

    Storing & Freezing

    Store any leftover soup in an airtight container in the fridge for up to 2 days. Alternatively freeze in an airtight container for up to 3 months.

    Notes

    RECIPE NOTES & TIPS
    Liquid Vegetable Stock - If you make your own Thermomix vegetable stock concentrate, you can make your own liquid stock. The ratio is 1 tablespoon of concentrate for every 500ml of water. A good quality, shop-bought liquid stock will also be perfectly fine to use!
    Pureeing the Soup - Leaving the soup uncovered for about 5 minutes will cool it enough to safely purée or blend it. If you skip this step, there is a risk that the steam from the hot soup will build pressure in the food processor or blender. This may cause the lid to loosen or come off and could result in burns.
    Freezer Friendly - Allow the soup to cool completely and then freeze in airtight containers for up to 3 months. Defrost and reheat in the microwave or on the stove-top.
    Storing & Freezing - Store any leftover soup in an airtight container in the fridge for up to 2 days. Alternatively freeze in an airtight container for up to 3 months.
    Serving suggestions:
    Crusty white bread rolls, Sourdough bread, Savoury muffins or Pull-apart loaf.

      This sounds amazing, can’t wait to make it! Do you just use the florets from the cauliflower and broccoli or do you add everything (stems etc). Thanks!

        I'm wanting to make this with home grown broccoli and cauliflower but need to avoid both onion and garlic; will this still work without it or should I replace it with something else?
