How to Make Irish Potato Soup | Creamy St Patrick’s Day Soup
Melt Butter: In a stock pot over medium heat, add 2 tablespoons of unsalted butter. Once it’s completely melted and starts to foam, toss in the diced onion and celery. Cook for about 3-4 minutes, until the edges begin to lightly brown and the onions turn translucent, filling your kitchen with a fragrant aroma.
Add Ingredients: Now, grab the 1.5 pounds of cubed russet potatoes and toss them into the pot. Pour in 24 ounces of vegetable broth along with ½ teaspoon salt and ¼ teaspoon pepper. Stir it all together, then bring the mixture to a simmer.
Cook Until Tender: Cover the pot and reduce the heat to low. Let the soup cook for 10-15 minutes. Keep an eye on it until the potatoes can easily be pierced with a fork. This step is crucial; don’t rush it, as you want those potatoes to become wonderfully tender.
Blend Smooth: Carefully remove the pot from the heat and allow it to cool for a couple of minutes. Using an immersion blender, blend the soup until smooth. Alternatively, if using a standard blender, transfer the soup in batches. Make sure to remove the center cap to allow steam to escape and cover it lightly with a kitchen towel. Just a quick reminder: never fill a blender more than halfway with hot soup to avoid spills!
Finish with Milk: Pour the blended soup back into the stock pot (if you used a standard blender) and return it to the stove over medium-low heat. Slowly add the 8 ounces of whole milk, stirring constantly, until well combined and heated through to your liking.
Serve: Dish out this comforting soup into bowls while it’s still warm. Top it with your favorite garnishes, like chopped parsley, crunchy croutons, shredded cheese, or crispy crumbled bacon! Enjoy every delightful spoonful!

Storing & Reheating
Store any leftover Irish Potato Soup in an airtight container in the refrigerator for up to 4 days. When at room temperature, it’s best enjoyed fresh. If you’ve made a larger batch and want to keep it longer, you can freeze the soup for up to 3 months. Just be sure to cool it completely before transferring it to a freezer-safe container. When it’s time to reheat, gently warm it in a pot over low heat, stirring frequently. Note that the texture may change slightly in the fridge or freezer, so adding a splash of milk during reheating can help restore that creamy consistency.
Chef’s Helpful Tips
- Avoid browning the onions too much as it can introduce a bitter flavor. Just cook them until they’re soft and translucent, releasing their sweetness.
- To achieve the best texture, ensure your potato cubes are uniform in size for even cooking.
- If you want a richer flavor, consider using chicken broth instead of vegetable broth.
- For a dairy-free option, simply substitute the whole milk with non-dairy milk like almond or oat milk.
- If the soup seems too thick after blending, feel free to add additional broth or milk until you achieve your desired consistency.
- This soup can also be made ahead of time, allowing the flavors to meld overnight for an even tastier dish!
Irish Potato Soup is not just a recipe; it’s a warm hug in a bowl. Whether it’s a simple weeknight dinner or a festive St. Patrick’s Day feast, this creamy delight is sure to satisfy. The balance of flavors and the comfort it brings might just make it your new favorite soup. Don’t hesitate to experiment with toppings and enjoy every spoonful!
Recipe FAQs
Can I make Irish Potato Soup vegan?
Absolutely! Swap the whole milk for a non-dairy alternative like coconut milk or almond milk, and use vegetable broth to ensure it’s completely vegan.
How can I thicken the soup?
If you prefer a thicker consistency, you can add a tablespoon of cornstarch mixed with some broth and stir it in, or blend in an extra potato.
What can I add for extra flavor?
Feel free to throw in herbs like thyme or chives, or even a splash of lemon juice for some brightness.
Can I use other types of potatoes for this soup?
Yes! While russets are perfect for their creaminess, you can use Yukon golds for a slightly different flavor and texture. Just keep in mind that some potatoes may not blend as smoothly.
