What to Serve with Cauliflower and Potato Soup

Sides

Crusty bread makes the perfect accompaniment to this soup. Of course, you could take things further and make your own cheesy garlic bread or chia seed bread, both of which would taste fantastic with this soup. If you have spare potatoes you could also make kartoffelbrot.
You could even go for a classic sandwiches and soup pairing. Try this wonderful steak and caramelised onion sandwich or a brie sandwich with chicken, pear and balsamic onions or keep it simple and serve your soup with a hummus sandwich.
Cheese never fails to please! Add a side of parmesan crisps for a truly special double act. Or serve with a side plate of parmesan parsnips.

Keep it simple and sprinkle some croutons on top of your soup.

Variations To This Recipe

Add cooked chicken or turkey to your soup to bulk it out and turn it into a more filling soup.
You can use vegetable stock or, for extra richness, chicken broth. If you want a real hit of richness, add my homemade turkey stock.
For a richer low salt stock, use a low sodium chicken broth.
Use any mixture of your favorite herbs for this soup recipe. I’ve gone for chives, but you can use fresh thyme, fresh parsley, oregano, rosemary, mint, marjoram, basil or sage... even wild garlic!
Add some cream or coconut milk to make this a creamy soup.
A a few turns of freshly ground black pepper to add a final flourish to your soup.
Not in a hurry? You could roast the cauliflower in the oven for an even more intense flavor. Simply drizzle with olive oil and roast in baking tray for 30 minutes in the oven. You could also bulk up your soup and roast other vegetables like carrots or parsnips – again, drizzle with olive oil and roast for 30 minutes, or until softened.

Popular substitutions

If you prefer a milder onion flavor, replace the onion with sliced green onions
You can use olive oil in place of vegetable oil

Top Tip

Get fresh locally sourced ingredients when making soup. It makes all the difference! Also, be sure to stick to the ratios below for the perfect silky smooth texture.

What are the best potatoes to use for cauliflower and potato soup?

There are a few options when it comes to choosing the ideal potato for this soup:

Russet potatoes – these potatoes are very high in starch and will produce a light and fluffy texture. They are particularly good for roast potato recipes and mashed potato, but they also work well in soup recipes, particularly if thick and creamy is your favorite kind of soup

Yukon gold potatoes – a great all-rounder, Yukon gold are medium-starch potatoes and contain more water than russets. They produce a nice texture, particularly in a cauliflower soup

White potatoes – these waxy potatoes are widely available and make a good option for soup recipes

How do you prepare cauliflower?

Preparing cauliflower from scratch is easy... if you know how!
Here's how to prepare cauliflower for this cauliflower potato soup recipe:

Pull off the excess leaves from the cauliflower. You'll be left with the big stem.

Cut off the whole stem of the cauliflower using a sharp chef's knife. Make sure you use a quality non-slip chopping board.

Using a small paring knife, remove each cauliflower floret from the head of the cauliflower one at a time. Place each floret into a bowl of water.

Quickly wash the cauliflower florets and remove them, placing them on a clean surface or container ready to be used in your soup.

Can I use frozen cauliflower florets for this recipe?

Yes, you can use frozen cauliflower for this recipe. However, you will get better results if you use fresh cauliflower, as frozen cauliflower will produce a lot of water, which will thin your soup and detract from the taste.

How do I store leftovers?

Storing cauliflower and potato soup leftovers is simple. First, allow the soup to cool completely. Once cooled, transfer the soup to a suitable airtight storage container. Then put it in the fridge, where it will stay fresh for 3-4 days.

Can you freeze Cauliflower and Potato Soup?

Absolutely! Cauliflower and potato soup is easy to freeze. Again, you will need to allow it to cool completely, before placing it in an airtight container, one that is suitable for freezing.

Your soup leftovers will last up to 6 months in the freezer. If you've made a big batch, it might be a good idea to freeze your soup in smaller individual portions. That way, you can defrost only as much as you need each time.

Can this recipe be scaled?

Yes! This cauliflower and potato soup is great for making a big batch. Simply double or triple the amounts below.

Don't forget, the ratios are very important. As long as you keep weights and measurements relative (so, if you're doubling the recipes, make sure you double everything) then your soup will end up perfect!
