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. Wait until it melts and begins to bubble slightly.
Sauté Aromatics: Once the butter is melted, toss in 1 medium diced onion and 2 diced celery ribs. Cook for about 3-4 minutes, stirring occasionally, until the onions are translucent and the edges of the celery begin to soften.
Add Potatoes & Broth: Stir in 1.5 pounds of peeled and cubed russet potatoes along with 24 ounces of vegetable broth, ½ teaspoon of salt, and ¼ teaspoon of pepper. Ensure everything is well mixed, then bring the mixture to a gentle simmer.
Simmer Until Tender: Cover the pot and reduce the heat to low. Let it cook for 10-15 minutes, or until the potatoes can be pierced easily with a fork. Keep an eye on the timer to avoid overcooking!
Blend the Soup: Remove the pot from the heat and let it cool for a couple of minutes. If you have an immersion blender, this is the perfect time to use it! Blend the soup until smooth. If using a standard blender, transfer the soup in batches. Remember to remove the center cap from the lid and cover it with a kitchen towel for safety.
Return to Pot & Add Milk: Pour the blended soup back into the stock pot if you used a standard blender. Heat the soup over medium-low heat, adding 8 ounces of whole milk. Stir gently until it’s heated through without boiling, adjusting with more broth if necessary.
Serve Warm: Dish out the creamy potato soup into bowls and top with your favorite garnishes. Chopped parsley, croutons, shredded cheese, or crumbled bacon all make delightful additions!

Storing & Reheating
To store your Irish Potato Soup, allow it to cool completely before transferring it to an airtight container. It can stay at room temperature for about 2 hours but should be refrigerated for longer storage, where it can last for up to 3-4 days. For extended preservation, freeze the soup for up to 3 months. When reheating, warm it gently on the stove over medium heat for about 10 minutes or until heated through. Keep in mind that the texture may thicken when frozen, so adding a splash of milk or broth can help bring it back.
Chef’s Helpful Tips
- Check for doneness by piercing potatoes with a fork. They should be fork-tender but not mushy.
- Use room temperature ingredients, particularly the milk, to avoid shocking the soup’s warmth.
- If you want a textured soup, blend only half of the soup and leave the rest diced. This creates a delightful contrast.
- Feel free to adjust the seasoning to taste, as some vegetable broths can vary in saltiness.
- For a spicier kick, add a pinch of red pepper flakes or some sautéed garlic.
Irish Potato Soup is a fantastic blend of simplicity and delicious flavor that offers comfort in every spoonful.
