Pair the soup with some warm crusty bread to sop up every last drop of flavor in the bowl. A hearty loaf of Irish soda bread or French baguette is an excellent option that will complement the flavors in the soup.

If you want to make your meal more filling, you can add some protein to your plate. A piece of grilled chicken breast, sliced beef, or lamb chops would work well as an addition to this dish.

Make-Ahead, Storing and Reheating

If you’re planning to make this Irish-style potato onion soup for a crowd, it’s possible to make ahead and store properly. This soup recipe can be prepared in advance, stored in the refrigerator for up to 3 days or frozen for up to 1 month. Just make sure that you cool the soup completely before refrigerating or freezing. And when reheating, warm it up slowly over low heat rather than heating it too quickly, which can result in an undesirable texture of the potatoes.

To reheat, use the stovetop method, simply transfer the soup back to a pot and place it over low heat. Warm it slowly stirring occasionally until heated through. You may need to add more stock if the soup has thickened in the refrigerator or freezer.

Alternatively, you can use a microwave-safe container and heat it up in the microwave on high power for about 2-3 minutes. Stirring often after each minute until heated through. Just bear in mind that microwaving can lead to unevenly heated food, so remember to stir and check frequently and use a microwave-safe dish with a lid that you can easily remove.

If you’ve got leftovers after reheating once or cooked batches in advance, store them properly by cooling them down quickly and placing them in airtight containers. For longer storage of leftovers or make-ahead portions, label your containers with cooking date to avoid confusion with expiry dates – freeze them as soon as possible.

Refrigerated soup leftovers are only good for three days once cooked, while frozen ones last from one to two months depending on how well they’re stored. When you want to serve these again, defrost them slowly overnight in the fridge before reheating.

Tips for Perfect Results

For a perfect Irish-style potato onion soup, there are several tips to bear in mind. Firstly, when cooking the onions, it’s crucial to let them cook gently until they turn a rich caramel color. This process will give the soup its deep flavor and characteristic sweetness.

Secondly, using good-quality stock can make a big difference in the taste of the soup. I recommended using vegetable or chicken stock instead of water to add more depth and richness to the soup. If you prefer a more robust flavor, you could also try using beef stock.

Thirdly, be careful not to overcook the potatoes. Overcooking can cause them to break down and turn mushy, which will affect the texture of the soup. For best results, boil the potatoes until they’re almost tender and then add them to the soup.

Fourthly, don’t skimp on butter or olive oil when cooking this recipe. Adding an ample amount of butter or olive oil will give your soup that extra richness and creaminess that makes it truly delicious.

Fifthly, if you want to make an Irish-style potato onion soup with a twist, try adding some finely chopped lean bacon when cooking the onions. The bacon adds an extra layer of smokiness that pairs perfectly with the richness of the soup.

Sixthly, for those who love beer: you can replace part of the vegetable stock with Guinness beer (brewed in Ireland) to give that additional traditional Irish taste.

Finally, don’t skip garnishing with fresh chives at the end! Fresh chives provide a pop of freshness that offsets the deep flavors of the soup and are a great finishing touch.


Now that you have mastered Irish-Style Potato Onion Soup recipe, it is common to have questions and curiosities about different aspects of the cooking process. Here in the FAQ section, I will answer some of the frequently asked questions, from what the difference is between Irish-style and French onion soup to how to make this recipe in a slow cooker with Guinness.

What is the difference between onion soup and French onion soup?

There is a distinction between onion soup and French onion soup. Onion soup involves using various types of onions while French onion soup primarily uses yellow onions. Additionally, French onion soup is exclusively made with beef stock while other types of stock or broth can be used in onion soup.

What is Julia Child’s recipe for French onion soup?

To make a savory and hearty British onion soup, we’ll need a combination of butter and light olive oil or fresh peanut oil to sauté our star ingredient: thinly sliced onions. With a sprinkle of salt and sugar to aid in browning, we’ll cook the onions until they’re golden brown and caramelized. Then, we’ll add in a little bit of flour to thicken the soup as we pour in the beef stock, followed by a generous amount of Cognac, Armagnac, or other fine brandy, and a cup of dry white French vermouth. Let’s get started on this classic recipe!

What is the best thickener for potato soup?

To thicken up the soup, I like to make a slurry by mixing cornstarch with water or some chicken stock from the soup. Once the soup is gently simmering, I add the slurry to it and whisk it in. You’ll notice the soup thickening up almost right away.

How do you make potato soup not gluey?

When preparing soup, the potatoes can potentially make the broth overly thick and slippery. To prevent this from happening, I suggest using a potato masher or a large fork to blend the potatoes into the soup. Alternatively, running the solid ingredients of the soup through a food mill can also help crush them and avoid sliminess.

Bottom Line

In conclusion, this Irish-Style Potato Onion Soup recipe is a must-try for anyone who loves traditional Irish flavors. Even those who are not familiar with Irish cuisine will fall in love with the rich and hearty taste of this soup. The combination of potatoes and onions creates a creamy texture that is both satisfying and comforting, making it a perfect option for cold winter nights.

Not to mention, this recipe features several substitutions and variations that allow you to customize the soup to your liking. You can add bacon for a smoky flavor or guinness for an extra depth of taste. And with its easy-to-follow instructions, even those who are new to cooking can create a delicious bowl of Irish-inspired soup.

Whether you’re looking for something to serve as a side dish or as a main course, this soup fits the bill. Just make sure to save some leftovers as they taste even better the following day.

In the end, I strongly recommend giving this recipe a try. Trust me; once you do, it’ll become a staple in your recipe box, guaranteed to please your guests every time. So grab your favorite pot, cook up some potatoes and onions, and sit back and enjoy a bowl of hearty Irish-style goodness.
