- 24 ounces vegetable broth: This is the liquid base that ties everything together. You can swap it out for chicken broth if you prefer.
- ½ teaspoon salt: Enhances the overall flavor. Adjust to taste, especially if using salted broth.

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. Allow it to melt while you chop the vegetables, filling the kitchen with a lovely aroma.
Sauté Vegetables: Once the butter is melted, toss in the diced onion and celery. Cook for 3–4 minutes until the edges turn lightly golden and the onions become translucent. The kitchen should smell warm and inviting at this point.
Simmer Ingredients: Add the cubed potatoes, 24 ounces of vegetable broth, ½ teaspoon salt, and ¼ teaspoon pepper. Increase the heat until the mixture comes to a simmer, then cover and reduce the heat to low. Allow everything to cook for 10-15 minutes, or until the potatoes are easily pierced with a fork.
Blend Until Smooth: Remove from heat and let the soup cool for 2-3 minutes. Use an immersion blender to carefully blend until smooth, or, if using a standard blender, transfer the soup in batches. Make sure to remove the center cap from the lid and cover it with a kitchen towel to let steam escape.
Heat with Milk: Once blended, pour the soup back into the stock pot if necessary. Over medium-low heat, stir in 8 ounces of whole milk until fully incorporated. Heat the soup until it reaches your desired temperature, stirring occasionally.
Serve Warm: Ladle your creamy Irish potato soup into bowls and serve warm. Top with chopped parsley, croutons, cheese, or crumbled bacon for extra flavor and fun.

Storing & Reheating
To store your Irish Potato Soup at room temperature, allow it to cool completely and keep it for no more than two hours. When refrigerating, transfer the soup into an airtight container for up to 5 days. If you wish to freeze it, scoop the cooled soup into freezer-safe containers, leaving an inch of space at the top, and it’ll stay good for about three months. For reheating, gently warm the soup on the stovetop over low heat, stirring often until heated through. Keep in mind that freezing may slightly alter the texture, so add a splash of milk or broth to refresh the consistency.
Chef’s Helpful Tips
- Avoid overcooking the potatoes, as they can become too mushy. Keep an eye on them while simmering.
- If you want a stronger flavor, consider adding garlic or herbs like thyme to the sautéed vegetables.
- Make sure to let the soup cool briefly before blending to prevent splatters.
- You can prepare the soup ahead of time and reheat it for busy weeknights.
- If you’re looking for a chunkier texture, reserve some potato cubes, add them back to the blended soup, and stir.
- Experiment with toppings—diced green onions or crispy shallots can add delightful crunch and flavor!
No matter the occasion, this Irish Potato Soup is a fantastic dish that warms the soul and brings comfort to the table. Its creamy texture and hearty flavor make it the perfect choice for family dinners or festive gatherings. Don’t be afraid to play around with the ingredients and make this soup your own.
