Cauliflower and Potato Soup

Why we love this recipe:

We love soup recipes that are both simple to prepare and comforting and delicious to eat. My Cauliflower and Potato Soup is all of those things, along with being incredibly nutritious.

This soup also happens to be vegan and gluten-free, so it is suitable for many people with dietary requirements.

It is a great soup to make a big batch to have on hand – I like to have some in the freezer for a quick lunch or dinner option, or when I am just too tired to cook!

Even if you are not a lover of cauliflower as is, I am sure you will enjoy this soup – it really does have such great texture and flavour!

Ingredients in this recipe:

Please see the recipe card further along in the post for exact quantities of ingredients and the full method.

Cauliflower – if you find that cauliflower is not in season, you can also use frozen cauliflower.

Potatoes– although any type of potato does work, I generally prefer to use a starchy variety or an all-rounder.

Brown/yellow onionand garlic– indispensable as a flavour base in this soup.

Olive oil– just a small amount to saute the vegetables. Coconut oil also works well.

Vegetable stock– you can make your own or use a commercial variety.

Fresh thyme and parsley– delicious fresh herbs add great depth of flavour. You can also use dried, but I would start with less as dried herbs can have much more potency.

Sea salt and pepper– to taste.

Step by Step Instructions:

Roughly chop your onion and garlic. Heat up the olive oil in a large saucepan over medium heat. Add in your onion and sauté for 5 minutes. Then, add in the garlic and cook for a further two minutes.
Add the cauliflower florets, potato, stock and thyme leaves.
Cook until the vegetables are tender.
Using an immersion blender or similar, blend until the soup is a smooth consistency. Check that the seasoning is to your liking.

Tips for Success and FAQs:

Make sure that the cauliflower and potato are cooked before attempting to blend them. It will be impossible to blend it smoothly if they are slightly undercooked.

You can use an immersion blender – I do. You will get a smoother, creamier texture if you use a blender. However, it is important to understand that blending hot liquids in a blender can be dangerous and could result in severe burns.

If you do use a blender for hot liquids, you must be careful. You will need to remove the central cap in the blender lid and then cover the lid with a folded tea towel to let the steam escape. Hold the lid on securely and blend on a low speed. This will allow steam to escape so that it doesn’t build up. Not doing this can pose a risk that soup may overflow out of the blender.

Make this soup your own. The basic recipe is vegan and gluten-free and delicious as it is. However, if you do not have specific dietary restrictions you can tailor it to your own requirement.

Ingredients

For the Soup:

▢ 2 tablespoon extra virgin olive oil See Note 1
▢ 1 large brown/yellow onion – roughly chopped
▢ 3 cloves garlic – peeled and chopped
▢ 500 gm (17 ounces) cauliflower – divided into florets See Note 2
▢ 2 medium potatoes – peeled and chopped
▢ 3 cups (750 ml) vegetable stock
▢ 2 teaspoon fresh thyme leaves
▢ sea salt and black pepper to taste
▢ ¼ cup fresh parsley leaves See Note 3

To Garnish: (optional)

▢ fresh parsley leaves
▢ finely grated lemon zest

Instructions

Heat the olive oil in a large saucepan over medium heat.
Saute onion about 5 minutes, stirring occasionally, but do not let it colour.
Add garlic, saute about 2 minutes. Be careful it does not burn.
Add the cauliflower, potato, vegetable stock and thyme leaves.
Season with salt and freshly ground black pepper.
Bring the mixture a boil, then reduce the heat, and simmer 15 minutes, or until the vegetables are tender.
Remove the saucepan from the heat and add the parsley leaves. See Note 3.
With a hand mixer, or in a blender, puree the mixture until smooth. See Note 4.
Reheat in the saucepan, season to taste with salt and pepper. See Note 5.
Add a little finely zested lemon rind and some chopped parsley to the top of each of the bowls. See Note 6.

Notes

In Australia, the tablespoon is 20 ml or 4 teaspoons. In many other countries, the tablespoon is 15 ml or 3 teaspoons. You may have toadjust your measurementsaccordingly.
You can also use the core of the cauliflower –just be sure to cut into small pieces, so it cooks evenly.
Adding the parsley just before blending adds colour, flavour and nutrients.
If you do use a blender for hot liquids, you must be careful. You will need to remove the central cap in the blender lid and then cover the lid with a folded tea towel to let the steam escape. Hold the lid on securely and blend on a low speed. This will allow steam to escape so that it doesn’t build up. Not doing this can pose a risk that soup may overflow out of the blender.
Adjust the seasoning to your liking – we recommend using freshly ground black pepper and sea salt flakes for the best flavour.
A little finely zested lemon and additional parsley is a delicious flavour booster, and adds a bright tone to the soup.
