Ingredients In This Recipe
The printable recipe further down the page has the complete list of ingredients, including quantities and step-by-step instructions.
Broccoli – use a large head of broccoli and its stem. Cut the head into pieces. Peel the skin from the stem and cut it into bite-sized pieces. Wash well to remove any sand.
Cauliflower – use half a large cauliflower, remove any discoloration. Roughly chop the cauliflower into small bite-sized pieces and wash well.
Carrot and potato – these can be peeled or not. If you are leaving the skins on give them a good scrub before cutting. Cut the carrot into fine dice and the potatoes into small cubes.
Celery – cut this into fine dice.
Brown onion and garlic – these give a nice flavor to the soup especially when sautéed. These should be peeled and finely chopped.
Butter – The fat from the butter will enhance the flavors in the soup. Leave this out if you are making this vegan.
Olive oil – for sauteing the vegetables.
Chicken broth/stock – use homemade chicken stock, store-bought or make from stock powder. For a vegetarian/vegan alternative use vegetable broth or water.
Canned diced tomatoes – the canned tomatoes add flavor and richness to the soup.
Dried herbs – we like to use dried Italian herb mix because it goes so well with tomato and garlic. If you don’t have this use dried or fresh parsley or make your own Italian herb mix.
Step By Step Instructions
Image 1: Cut the onion, celery, and carrot into fine dice. Having the vegetables roughly the same size means they will cook quicker and be finished at the same time.
Image 2: This soup is not going to be pureed so, the broccoli, cauliflower, and potato should be cut into small even bite-sized pieces. Having bite-sized pieces not only speeds up cooking, but it also makes the soup easier to eat.
Making The Soup
- This soup is very easy to make once all your veggies are cut. It’s just a matter of sauteing the onion, carrot, garlic, celery in the olive oil and butter. Sauteing the vegetables will give a lovely flavour to the soup.
- Then add the stock (or water), tomatoes, potatoes and herb and bring to the boil. Reduce the heat and simmer for covered for 10 minutes.
- Add the broccoli and cauliflower and cook uncovered for 5 minutes or until the broccoli and cauliflower are cooked.
- To finish the soup season with salt and pepper.
If you prefer a smooth soup use an immersion blender to puree it smoothly while still in the pot.
This soup can stand on its own if you want something light and healthy for dinner. For something a little more filling, serve the soup with homemade bread like our Hawaiian dinner rolls or homemade cheese breadsticks.
