Ingredients You’ll Need
- 2 tablespoons unsalted butter: The foundation for sautéing the aromatics, providing a rich and savory base. Alternatively, olive oil can be used for a lighter option.
- 1 medium onion, diced: This adds sweetness and depth to the soup. Yellow or sweet onions are ideal.
- 2 celery ribs, diced: Provides a fresh crunch and enhances the soup’s flavor profile.
- 1.5 pounds russet potatoes, peeled and cubed: These starchy potatoes lend creaminess when blended. Yukon Gold can also be a delicious substitute.
- 24 ounces vegetable broth: A flavorful base. Keeping it low-sodium allows you to control the saltiness of the soup.
- ½ teaspoon salt: Helps to season the soup. Adjust according to your taste and the broth used.
- ¼ teaspoon pepper: Adds a subtle kick. Freshly cracked black pepper enhances flavor better than pre-ground.
- 8 ounces whole milk: Contributes creaminess and richness. For a lighter version, almond or oat milk works well.
How to Make Irish Potato Soup | Creamy St Patrick’s Day Soup
Melt the Butter: In a stock pot over medium heat, add 2 tablespoons of unsalted butter. Watch as it melts, shimmering and fragrant, before you add the veggies.
Sauté the Aromatics: Once the butter has fully melted, toss in the diced onion and celery. Cook for about 3-4 minutes or until the edges of the onions begin to brown and they turn translucent. The teasing scent of these ingredients will fill your kitchen, inviting everyone closer.
Add the Potatoes: Stir in the cubed russet potatoes, along with the 24 ounces of vegetable broth, ½ teaspoon of salt, and ¼ teaspoon of pepper. Bring this to a gentle simmer. Cover it up, then reduce the heat to low. Allow the mixture to cook for 10-15 minutes, or until the potatoes are tender enough to pierce easily with a fork.
Blend the Soup: Remove the pot from heat and give it a couple of minutes to cool. If you have an immersion blender, use it for an easy, seamless blend until smooth. If not, transfer the soup in batches to a standard blender, being careful not to overfill the jug and letting the steam escape through the lid. You want a silky texture throughout!
Reheat and Add Milk: Pour the blended soup back into the stock pot (if using a standard blender) and return it to medium-low heat. Stir in 8 ounces of whole milk, mixing until incorporated. Heat gently until warm, adjusting to your desired temperature.
Serve and Enjoy: Ladle the soup into bowls and serve it warm. It’s delightful topped with chopped parsley, croutons, or even crispy bacon bits for a delicious twist.

Storing & Reheating
To store any leftovers, let the soup cool completely at room temperature for no more than two hours. Move it into an airtight container and refrigerate for up to 3 days. If you want to keep it longer, consider freezing. Portion the soup into freezer-safe containers, leaving some space for expansion, and it will keep for up to 3 months. When you’re ready to enjoy it again, just reheat on the stovetop until heated through. Keep in mind the texture may slightly change after freezing, but a splash of milk can bring back its creamy consistency.
Chef’s Helpful Tips
- Avoid burning the butter by ensuring the heat isn’t too high during the sauté phase.
- For a creamier soup, you could add an extra splash of milk after blending for that perfect velvety touch.
- If you love a richer flavor, try roasting the potatoes beforehand for a caramelized touch.
- When blending, work in small batches to prevent any hot splashes or pressure build-up in the blender.
- Experiment with herbal finishes, like fresh chives or dill, for a fresh pop of flavor.
Irish Potato Soup is not only a cozy recipe but also a canvas for your culinary creativity. With its creamy essence and comforting flavors, you can easily adjust ingredients or toppings to suit your tastes. It’s perfect for any meal or occasion, whether it’s just you on a chilly night or for a crowd at a festive gathering. The warmth of this soup nurtures the soul and invites you back for more.
Recipe FAQs
Can I make Irish Potato Soup vegetarian?
Absolutely! Just use vegetable broth instead of chicken broth, which many people prefer for a lighter flavor. The recipe as it stands is already vegetarian-friendly.
How can I thicken the soup if it’s too thin?
If you find your soup is too thin after blending, you can thicken it by simmering for a few additional minutes to evaporate some liquid. Another great option is to blend in an extra potato for added texture.
Can I prepare this soup in advance?
Definitely! In fact, letting the soup rest in the fridge for a day allows the flavors to deepen. Just reheat before serving and adjust the thickness with additional milk if desired.
What toppings go well with Irish Potato Soup?
The possibilities are endless! For traditional flair, try crumbled bacon or chopped green onions. If you’re in the mood for something different, consider adding shredded cheese, a dollop of yogurt, or even your personal favorite herbs to finish it off.
