How to Make Irish Potato Soup | Creamy St Patrick’s Day Soup
Melt Butter: In a stock pot over medium heat, add 2 tablespoons unsalted butter. Let it melt completely, creating a deliciously fragrant base.
Sauté Vegetables: Once the butter has melted, toss in the 1 medium onion, diced and 2 celery ribs, diced. Stir and cook for about 3-4 minutes, until the onions are translucent and the edges are lightly browned. The aroma will begin to fill your kitchen, luring everyone into the room!
Add Potatoes and Broth: Now, add in 1.5 pounds russet potatoes, peeled and cubed, 24 ounces vegetable broth, ½ teaspoon salt, and ¼ teaspoon pepper. Bring this mixture to a simmer, cover the pot, and reduce the heat to low. Allow it to cook for 10-15 minutes, or until you can easily pierce the potatoes with a fork.
Blend the Soup: Once the potatoes are tender, remove the pot from heat and let it cool for about 2 to 3 minutes. Use an immersion blender to mix until smooth. If you’re using a standard blender, transfer the soup to batches but remember to take out the center cap of the lid and lightly cover with a kitchen towel to let steam escape. Carefully blend to creamy perfection.
Stir in Milk: If you’ve used a standard blender, pour the soup back into the stock pot. On medium-low heat, add 8 ounces whole milk and gently stir until fully incorporated and the soup is heated to your liking. This step is key for achieving that creamy texture everyone will adore.
Serve Warm: Finally, serve the soup warm in bowls, garnished with your favorite toppings. Try chopped parsley, croutons, shredded cheese, or crumbled bacon for an extra pop!

Storing & Reheating
Leftover Irish Potato Soup can be stored at room temperature for up to 2 hours before refrigerating. For longer storage, transfer to an airtight container and refrigerate for up to 3 days. You can also freeze the soup for up to 3 months; just use freezer-safe containers to keep it fresh. When you’re ready to enjoy it again, simply reheat on the stove over medium heat until warmed through. Keep in mind that freezing may slightly alter the texture, but a splash of milk while reheating can help smooth it out.
Chef’s Helpful Tips
- Avoid overcooking the potatoes; they should be fork-tender but not mushy.
- For even creamier soup, opt for fat-free half-and-half instead of milk to enrich the flavor.
- If you prefer a robust soup, feel free to add spices like thyme or fresh herbs for extra depth.
- Make this soup a day ahead; cooling it in the fridge allows the flavors to meld beautifully.
- Keep your blending tool handy. An immersion blender is a great investment for making soups!
Irish Potato Soup is such a wonderful dish that satisfies cravings and delivers comfort in every spoonful. With simple ingredients and minimal effort, it’s easy to prepare and will undoubtedly impress your friends and family. Don’t hesitate to experiment with the ingredients; maybe toss in some leeks or garlic for a flavor twist! Enjoy this delightful Irish classic, whether for St. Patrick’s Day or simply whenever you’re in need of a cozy bowl of goodness.
