Why You Will Love It
- Quick and easy - This kale soup is so simple to make. Just dump it all in the pan and let it cook away before blending. It only takes 20 minutes too.

Ingredients and Substitutions
A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.
- Oil - We used olive oil to cook everything in.
- Onion and celery - This is the base of the soup and gives it a really lovely flavour. Save yourself some time and use frozen onion instead.
- Potato - This is what makes the soup really filling. You can use any type of white potato, which makes it a budget friendly soup.
- Garlic - Just a little bit adds a lot of flavour. Fresh is always best, however you could use frozen garlic of crushed garlic in a tube if you prefer.
- Kale - The star of the soup. We used curly green kale.
- Stock - Try to use the best quality stock you can, as you really will be able to taste the difference. We used vegetable stock to keep this vegetarian, but you could use chicken stock which you have a richer flavour.
- Milk - This makes the soup lovely and creamy. You could leave it out though if you prefer.
- Salt and Pepper
Variations
This soup is pretty simple, and that's how we like it. There isn't a whole lot of room to change things around, as there are minimal ingredients. However, you could swap half the kale for spinach.
You could also serve some grated parmesan on top, which would add some extra creaminess when stirred in. You can swap the white potatoes for sweet potatoes, but that would really change the colour.
How to Make Kale Soup
- Step 1: Heat the oil in a large pan and add the potato, onion, garlic and celery. Sauté until softened - about 4 minutes.
- Step 2: Add the kale and stock. Simmer for 15 minutes.
- Step 3: Blend until smooth.
- Step 4: Add the milk and salt and pepper and stir in.
Serving Suggestions
To give the kale soup a bit of texture, you could serve it with some crunchy croutons on top. We make our own easy croutons by chopping up some bread into squares and drizzling over a little olive oil and a sprinkle of garlic granules and dried herbs.
Put them in the oven for about 5 minutes to crisp up. Perfect for adding to soups and salads. Or try our super quick Air Fryer Croutons.
You could keep it simple and serve the soup with some French bread fresh from the oven. Garlic bread is also great to dip in it, and that is a favourite with our kids.
You can't beat homemade bread, so why not serve this kale soup with our Garlic and Rosemary Focaccia, Easy Bagels or Easy White Bread.
Dannii's Top Tips
- We have used vegetarian stock to keep this soup vegetarian, however you could swap it for a really good quality chicken stock to give it a richer flavour.
- If you are making this for your children, then use a low salt stock and don't season the whole soup, just do individual bowls if wanted.
- If you want to make this look more presentable, then you can reserve some of the sautéed kale and then serve them on top of the soup with herbs.
- You don't have to add the milk, as the potatoes as really creamy. However we feel it gives it something a little bit special.
- If you are using a jug blender to blend this soup, then wait until it has cooled first as you could crack the jug if it is too hot.
- Make this soup more indulgent by sprinkling some cooked chopped bacon on top.
Frequently Asked Questions
The colour of the soup will depend on using the right amount of kale, and also how fresh it is. The fresher the kale, the more vibrant the colour will be.
To make this soup vegan, just swap the milk for a dairy free version like almond milk. Coconut milk would work too, but it would give it a coconut flavour.
Yes, you can make this in advance and then leave it to cool in the pan, cover and refrigerate the whole pan. Then, when you want to serve it you can put the whole pan (uncovered) on the hob and heat it through.
If you have leftovers of this soup, it will store in an air tight container in the fridge for up to 2 days.
Yes, this soup freezes really well. We usually make a double portion and either save some for the kids or we wait until it has cooled, put in freezer bags and then lay it flat in the freezer. To defrost, simple take out of the freezer and leave to defrost thoroughly. You can then heat it through in a pan.
If your soup is too thick, then you may have cooked it at too high a temperature. Simply add a little more stock until it is the desired consistency. Equally, if it is too thin that you might not have had the heat high enough. Let it simmer a little longer to thicken up. Adding the milk should help to thicken it up too.
