Traditional Irish Potato Soup is a lovely thing. It's a simple soup, yet it has the power to warm you up and comfort you. Great for lunch or supper.
This is a soup that takes the minimum amount of time and energy to make. There are many variations on the internet but trust me this one is well worth a try. It's smooth and silky texture along with its warming and comforting flavour makes this soup a real winter warmer.
This Irish Potato Soup is a simple soup with simple ingredients from a very simple time. That potato soup has stood the test of time is a testament to how good it is. Filling and warming this soup will keep you going until dinner. This recipe for Irish Potato soup stays very close to its roots. Just a few simple ingredients are all you need.
How to Make Irish Potato Soup:
- Start off by melting a generous amount of butter in a saucepan. Add the onion and cook until it is translucent.
- Then add the potatoes. You will need to use a floury potato for this soup, I use Maris Pier potatoes however any floury potato will work.
- Next add the stock, I use vegetable stock, however, if you are not vegetarian then a chicken stock will work well too. The other reason I prefer vegetable stock is that it doesn't take over from the flavour of the potatoes. Then I add some herbs, thyme I find is the perfect match for this soup as is bay. I add 4 or 5 sprigs to the soup and a dried bay leaf. Now let the soup simmer and as soon as the potatoes are cooked add the milk. Full fat milk will give you the best results, but if you are watching the calories then semi-skimmed will do too.
- Finally, fish out the thyme sprigs and the bay leaf then blitz for a smooth silky finish.
Can I Freeze Potato Soup?
Because of the milk in this soup freezing the finished product may result in the soup splitting when you reheat it. If you want to freeze this soup I would leave out the milk, blitz the soup, leave it to cool then freeze it. Add the milk to the soup when you have defrosted it and are ready to reheat it.
Can I Make This Soup Vegan?
Yes, you can. Make sure your vegetable stock is vegan then swap the butter for good vegan butter. Finally, swap the milk for a lightly flavoured plant milk, I think oat milk may be the best for this. Please note that I have not tested this soup to be vegan.

This is such a classic and makes me extremely hungry for some. Such a practical and budget friendly dish too!
This soup is gorgeous and I love how easy it is to make. Very versatile and great any time of the year. Perfect comfort food!
Fresh thyme tastes so delicate in this soup! The soup is so easy to make and just what we like on a cold day.
This soup looks so creamy and velvety in texture, would it be wrong to want to dip bread in it? The flavor of thyme in soup is one of my favorites, just enough without being in your face. I'm intrigued about the meat free cottage pie you're making for the celebrations!

I love potatoes in any form, but they are especially delicious as soup, and this one looks so deliciously velvety and simple to make, too. Happy St Patrick's Day!
Any recipe that starts with "generous amounts of butter" is a good one in my book! I love how simple this recipe is, and it looks wonderful. I'm definitely going to have to give it a try
