A thick, creamy traditional Irish potato soup, flavoured with onions, leeks and roasted garlic.
Make this Creamy Roasted Garlic Irish Potato Soup in less than an hour on the stove top. It’s a warm and comforting velvety soup with the mellow, buttery flavour of roasted garlic. Irish Pub food at its best!
I adapted this recipe from one I found in an Irish Pub cookbook I picked up years ago in San Francisco. We ate in the pub twice and had a hard time choosing from the menu, because everything sounded so good. On the way out, I knew I wanted to try to recreate some of the dishes at home, so I bought the book and tucked it in my suitcase. This Roasted Garlic Irish Potato Soup is my version of one of the recipes.
I like making soup. I know it’s easy to buy it pre-made in a store, but I like being able to control the ingredients and know exactly what is in it. I’ve made soup in a slow cooker, like this Slow Cooker Sweet Potato Turmeric Soup and in an Instant Pot, like this Instant Pot Potato Leek Soup with Bacon. Today, however, I decided to make a traditional Irish soup with a traditional method: in a pot on the stove top.
The best part of this soup is the one part you have do to ahead of time: roast the garlic. You can buy roasted garlic paste, but roasting your own is ridiculously simple.
How to roast garlic
Use a sharp, serrated knife to slice about half an inch from the top of a head of garlic. Remove as much of the papery bits from the outside as you can and discard. Place the head on a small square of aluminum foil and drizzle with olive oil, making sure it seeps in between the cloves. Sprinkle lightly with salt and pepper. Bring up the four corners of the foil and wrap tightly around the head. Roast at 375°F for 40 – 60 minutes or until garlic is very soft. Unwrap, let it cool, then turn it upside down and squeeze out the soft cloves. Mash with a fork or purée into a paste in a food processor.
Then, to make this Roasted Garlic Irish Potato Soup–
it’s simply a matter of sautéing onions and leeks, adding broth, potatoes and garlic and simmering until the potatoes are soft. Purée in batches in a food processor, or use an immersion blender to make that natural creamy texture. Stir in a little light cream, some parsley to temper the garlic, a generous sprinkle of smoked salt, garnish and serve!
