Ingredients You’ll Need

- 2 celery ribs, diced: Adds freshness and a subtle crunch; you can substitute with leeks if you prefer their milder taste.
- 1.5 pounds russet potatoes, peeled and cubed: The star of the dish, russet potatoes create a creamy texture when cooked and blended.
- 24 ounces vegetable broth: This gives the soup a flavorful body; feel free to use homemade stock or store-bought.
- ½ teaspoon salt: Essential for enhancing flavors; adjust to taste after blending.
- ¼ teaspoon pepper: Adds warmth, which can be increased if you enjoy a bit of a kick.
- 8 ounces whole milk: This contributes to the soup’s creaminess; half-and-half can be a rich alternative, or non-dairy milk for a vegan version.
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 until it’s fully liquefied and slightly bubbly.
Sauté Aromatics: Once melted, throw in your diced onion and celery. Stir them occasionally for about 3-4 minutes, or until the onions become translucent and the edges start to turn golden, creating a fragrant base.
Add Potatoes & Broth: Now, stir in 1.5 pounds of cubed russet potatoes, along with 24 ounces of vegetable broth, ½ teaspoon of salt, and ¼ teaspoon of pepper. Bring your mixture to a gentle simmer, cover the pot, and then reduce the heat to low. Cook for 10-15 minutes until the potatoes are fork-tender.
Blend Until Smooth: Remove the pot from heat and let it cool for about 2 minutes. Using an immersion blender, blend the soup until it’s silky and smooth. If you don’t have an immersion blender, transfer the soup to a standard blender in batches, remembering to remove the center cap on the lid and cover it with a kitchen towel to avoid steam buildup.
Reheat & Incorporate Milk: Pour the blended soup back into the stock pot if using a standard blender. Over medium-low heat, stir in 8 ounces of whole milk until fully incorporated and heated through to your preferred temperature.
Serve & Enjoy: Ladle the warm Irish Potato Soup into bowls and serve immediately. Top it with any of your favorites like chopped parsley, croutons, shredded cheese, or crispy crumbled bacon for extra flavor and texture.

Storing & Reheating
To store Irish Potato Soup, allow it to cool completely before transferring it to an airtight container. It can sit at room temperature for about 2 hours or in the refrigerator for up to 4 days. If you’d like to freeze some, pour it into freezer-safe bags or containers. It’s best enjoyed within 3 months. When reheating, warm it gently on the stove over low heat or microwave in short bursts until hot. Keep in mind, the texture might change slightly after freezing, but a splash of milk can help refresh it.
Chef’s Helpful Tips
- Don’t rush the sautéing process; browning the onions and celery will deepen the flavor of the soup.
- Ensure your potatoes are cut into even cubes for uniform cooking.
- If the soup is too thick, add more vegetable broth or milk until you reach your desired consistency.
- For a hint of extra flavor, consider adding fresh herbs like thyme or rosemary while cooking.
- If making ahead, prepare the soup without adding the milk, and stir it in just before serving to preserve its creaminess.
