This vegan adapted old-fashioned Irish potato soup recipe originates way back to the antique era of the 19th Century!
Old-fashioned potato soup is such a tasty, simple and amazingly budget-friendly recipe adapted from 'The Whitehouse Cook Book' [by F. L. Gillette and Hugo Ziemann] dated 1887.
Potatoes are so delicious especially when prepared into a creamy, comforting, nourishing soup that only costs pennies per pot full, and is guaranteed to happily fill up hungry tummies whilst simultaneously warming the body and soul.
Serve with wedges of warm wholewheat bread for extra wholesomeness that the whole family will love.

Origin of Irish Potato Soup
Potatoes were first cultivated in the Andes, South America more than 7000 years ago.
Sometime during the latter years of the 16th Century potatoes were brought over to Ireland but who exactly was responsible for the introduction is not clear.
Potatoes soon became a very popular inexpensive crop especially with the poorer members of Irish society who leaned heavily on the potato for valuable nutrition.
However the reliance on one vegetable crop was not ideal as when the potato crop succumbed to a disease, the Great Irish Famine or the Irish Potato Famine [1845-1852/55] was the terrible outcome.
The result of the famine included millions of Irish people having to rely on soup kitchens in order to prevent starvation, at least 1 million people dying, and about 1.5 million Irish immigrating to America.
Despite the Great Famine, the potato remains an important food for The Republic of Ireland [southern] as well as the separate Northern Ireland region, with an abundance of delicious potato recipes, and many different variations of potato soup.
The current recipe for Irish potato soup was adapted from an old recipe I found within the The Whitehouse Cookbook which was published in 1887 by the American author Mrs F.L Gillette.
As many Irish immigrants moved to American during the Potato Famine there would have been many traditional Irish recipes introduced to America which would have likely influenced Gillette and the recipes she included within her cookbooks, or perhaps she even had Irish descendants.

Vegan Plant-Based Irish Potato Soup
This vegan and plant-based potato soup recipe is prepared with simple every-day pantry ingredients. The recipe is adapted from an 1887 traditional potato soup recipe.
I have replaced dairy milk with plant milk. The type of plant milk that I used was oat milk [Co-op GRO The Oaty One brand]. For butter I used Flora dairy-free margarine.
There are no actual measurements for the original recipe, other than '8 medium potatoes, 'a lump of butter', 'a large onion', 'some herbs', and with instructions to 'thin it with rich milk'.
Also I mashed the cooked potatoes instead of 'pressing through a colander'. Although I am sure the different method achieved similar results.
If preferred the potato soup can be blended with an immersion stick blender or similar, which would achieve a much smoother soup.
This vegan potato soup recipe is so easy, quick and budget-friendly. If you have potatoes, an onion, plant milk and some seasoning, then a delicious wholesome meal can be achieved with not much cooking on the stove-top.

As soon as the potatoes have cooked the soup is practically ready, except for a little reheating after the cold milk is poured in.
I have used dried mixed herbs but really any dried or fresh herbs can be used for this Irish potato soup recipe, just chuck in whatever you have to hand.
Instead of simply cooking the potatoes in water, I choose to cook in veggie stock/broth for extra flavour. However, if you don't have vegetable stock then just use water.
Vegan Irish potato soup is a creamy soup similar to a traditional chowder but with less ingredients and fuss! A bowl is extremely satisfying and comforting, and so warming especially good for inexpensive family meals.

How To Prepare Irish Potato Soup
Place the potatoes, chopped onion, and mixed dried herbs into a large soup pot.
Season with salt and pepper.
Bring to the boil and simmer until the potatoes are soft.
Pour in the plant milk and add the vegan margarine.
With a fork stir the potatoes into the milk.
Bring the soup back up to the boil, stir frequently.
Garnish with chopped chives or parsley, or both.
A sprinkle of nutritional yeast flakes is a tasty addition.
Recipe Notes
Leftover potato soup can be stored within the refrigerator for up to 3 days.
Yes.
Freeze for up to 3-4 months.
Defrost completely before reheating.
Place the potato soup into a non-stick pan and add extra plant milk if required to loosen the soup up.
Very gently bring the soup to a boil, stirring frequently, but don't fast boil as the milk may split.
Once the soup is at the boiling point it is ready to enjoy.
Yes.
It is easy to prepare this potato soup recipe as free from gluten ingredients.
Simply choose a gluten-free veggie stock.
A few ideas:
* Irish soda bread [100% wholewheat recipe]
* quick dinner rolls
* American biscuits
* cornbread
* British plain scones
* your favourite bread/rolls/baps
* Scottish oatcakes
* saltine crackers, crackers
* rice cakes/ corn cakes/ rye cakes
* shredded vegan cheese
* nutritional yeast flakes
* chopped fresh herbs such as chives, parsley, dill
Any variety of potatoes that are high in starch and good for mashing or roasting are perfect for potato soup.
Such as:
* white potatoes [in the UK ordinary potatoes can be simply labelled 'white potatoes']
* Maris piper
* Russets
* Yukon Gold
* King Edward
***For a delicious change try this potato soup recipe with sweet potatoes. Surprisingly, during the 18th and 19th Century sweet potato recipes were very popular in Britain.***
Absolutely!
My family prefers the additional rustic texture that simply mashing the potatoes with a potato masher brings, so I tend not to blend the soup.
However, if a smoother, silkier soup is preferred then use a stick or immersion blender and give the soup a little whizz just until blended.
Don't blend too much as the potatoes could become too gloopy or gluey if too much starch is released.
Of course not.
Many people follow a no-added fat plant-based diet and prefer to not add ingredients such as margarine or vegan butter to their meals.
Instead of the margarine, replace it with one tablespoon of white miso paste and ensure the miso is fully incorporated and mixed into the soup.
Or add a few tablespoons of nutritional yeast flakes at the same time as the margarine is added.
Using white miso paste or nutritional yeast flakes adds extra savouriness to the soup.
[White miso paste can be found in most health/wholefood stores, and is also available in Asda, UK supermarkets.
Nutritional yeast flakes can also be found in most supermarkets and wholefood stores.
Both ingredients may initially cost a few pounds but they will be able to be added to many more meals and can give inexpensive meals a flavour and nutrition boost.]

📖 Recipe

Traditional Irish Potato Soup [vegan]
Equipment
- Large non-stick pot/soup pot
- potato masher or if preferred a smooth soup a stick/immersion blender
Ingredients
- 1 kilogram potatoes [1000 grams] chopped, large potatoes can be quartered and smaller halved
- 1 large onion [about 190 grams] rough diced
- 1 tablespoon dried mixed herbs
- 1 litre vegan stock broth
- 250 mililitres plant milk use more if a thinner soup is preferred
- 1 tablespoon plant margarine or 1 tablespoon of white miso paste or 2 tablespoons of nutritional yeast flakes
Instructions
- Add the potatoes, onions, dried herbs and vegetable stock to a large saucepan.
- Season with salt and pepper.
- Bring to the boil and simmer until the potatoes are cooked, this usually takes around 12-15 minutes depending on your potatoes.
- With a potato masher give the potatoes a good mashing.[or if preferred a smoother soup use a stick or immersion blender.]
- Pour in the plant milk and pop in the vegan margarine.
- Using a fork or spoon stir the milk and margarine through the potatoes until everything is combined.[Use more plant milk if a thinner soup is liked better]
- Taste the seasoning and add enough salt and pepper to taste.
- Gently bring the soup back to the boil, but do not boil as doing so may cause the milk to split. Stir frequently.
- Once the soup is at the boil it is ready.
- Garnish each serving with chopped chives or parsely, or both. A sprinkle of nutritional yeast flakes is a tasty addition.
- Serve with your favourite bread, roll or bap for a filling delicious meal.
Notes
- Nutritional information is provided for guidance only and is not a strict calculation as ingredients vary.
- Store leftover soup within the refrigerator for 3 days.
- Or within the freezer for 3-4 months.
- Reheat gently and don't boil as the milk may separate.
- If the milk does split it won't affect the flavour and can just be stirred well before eating, but once the soup sits it will likely split again. Sprinkle some nutritional yeast flakes over to hide the split milk if necessary!
- This soup is low in calories but is hearty enough to fill you up especially when served with a slice of wholemeal/wholewheat bread. I usually manage to get 6 small bowls of soup with just the right amount, but of course for hungrier appetites 4 servings may be better.
- For gluten-free potato soup choose a gluten-free veggie stock.
- For a margarine free potato soup replace the vegan margarine with a tablespoon of white miso paste. Do make sure you whisk the miso through thoroughly.
- Or replace the margarine with 1-2 tablespoons of nutritional yeast flakes.
- This recipe makes a nice thick potato soup but of course if you prefer a thinner soup, just add more plant milk and stir through to thin to the desired consistency.
- Prefer to keep the peel on the potatoes? If your potato skins are unblemished then just give them a little scrub and chop up for the soup. If the skins are not too good then its best to peel these off.
