Creamy and comforting, this plant-based spiced celeriac soup is an easy recipe you can make for lunch at home or a light dinner. It's a nutritious recipe packed with vegetables and a great way of using celeriac when it's in season.
I find one celeriac root is often too big for one recipe. If I buy it, I need to use it at least twice so it doesn't go to waste. So what do I do?
I make soup! Soup is such a great way of avoiding food waste by using up vegetables that might otherwise hide at the back of the fridge slowly going limp and soft.
Celeriac is one of those vegetables that once you cut into, it doesn't last that long. It does go a little soft but is still perfect for soup.
But what does celeriac taste like?
Celeriac tastes a little earthy. It's a bit like a turnip but with a fresh celery flavour. Although it's in the same family as celery, it's actually a different vegetable and not just the root.
What ingredients do you need for this celeriac soup?
For this creamy vegan soup you'll need just:
- Celeriac, also known as celery root
- Potato - Use a floury variety such as Maris Piper or King Edward ones. They help to make the soup nice and creamy.
- Spices: cumin, coriander and turmeric
- Vegetable stock - Use homemade or bought stock or a stock cube.
How do you make spiced potato and celeriac soup?
This vegan celeriac soup is really easy to make in a saucepan. Basically you cook the onions until softened and then add the garlic and spices. Then the rest of the vegetables and stock and simmer until the potato and celeriac are cooked through.
You can then use a stick blender to blend it or transfer it into a blender jug in batches to blend.
Can you make it in a soup maker?
Yes, if you have a soup maker then just put all the ingredients in and cook according to the instructions for your machine.
If you're working from home it's a really easy option as there's almost no hands on time.
Personally I often use my Froothie Evolve blender which has a smooth soup setting. It cooks the soup and then blends it for me and the whole cooking blending process takes about half an hour.
Do check out my review post if you'd like more information about the Froothie blender. It is a brilliant high speed blender that's amazing for making soups, smoothies and even ice cream!
What to top this spiced celeriac soup with?
There are so many things you could top this soup with. In these pictures I've topped it with some homemade croutons and some chopped parsley.
You could also try:
- Other herbs. Rosemary or thyme or coriander would be nice.
- Spicy roasted chickpeas
- A swirl or yogurt, creme fraiche or sour cream
What to serve with celeriac soup?
I always like to have some bread with a soup like this. If I have the time then nothing beats freshly baked bread.
If you're feeling indulgent then why not try this garlic and herb butter quick bread?
This soda bread with yogurt is also a quick and easy homemade bread option.
How long does it keep for?
You can keep this spiced celeriac and potato soup in the fridge for up to three days. Reheat it in a saucepan or in the microwave until piping hot. You may need to add a splash of water.
Can you freeze it?
Yes. It will keep well in the freezer for at least three months. I usually freeze it in individual containers so it's easy to defrost the amount we want.
You can defrost it in the fridge overnight or on the kitchen counter or in the microwave.
Then reheat until piping hot before serving.
How can you adapt the recipe?
There are lots of ways you can adapt this recipe. Why not throw in a few more vegetables? If you have something that needs to be used up then go ahead and add it. Soup is a great way of avoiding food waste.
If you want to tweak the spicing then go ahead. Why not add a bit more cumin if it's your favourite spice? Or a bit less if you're not quite so keen.
If you just miss out one of the spices this vegan celeriac soup will still be really tasty!
What else can you do with celeriac?
Celeriac is delicious roasted as a vegetable side dish. You can also mash it.
I like to make it into a coleslaw. This carrot and celeriac salad is a great one to start with!
You can even roast it whole. Why not try this whole roasted celeriac with a creamy mushroom sauce?
