Ingredients You’ll Need
- 2 tablespoons unsalted butter: Used to sauté the vegetables, giving the soup a rich flavor. You can replace it with olive oil for a dairy-free option.
- 1 medium onion, diced: Adds sweetness and depth. Yellow onions work best, but you can also use shallots for a gentler flavor.
- 2 celery ribs, diced: Contributes a fresh, aromatic note. If you don’t have celery, leeks make a great substitute.
- 1.5 pounds russet potatoes, peeled and cubed: Provides the base of the soup with creaminess. If desired, substitute Yukon Gold potatoes for a buttery taste.

- 8 ounces whole milk: Introduces a creamy texture and richness. For a lighter option, you can use half-and-half or a dairy-free milk alternative.
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. Once melted, the butter will carry the tantalizing smell of cooking.
Sauté Vegetables: Add 1 medium onion, diced, and 2 celery ribs, diced. Stir occasionally, cooking until the edges of the onion start to lightly brown and turn translucent, which should take about 3-4 minutes. A hint of appreciation for the sweet aroma is often what makes this step worthwhile.
Add Potatoes and Broth: Next, toss in 1.5 pounds russet potatoes, peeled and cubed, along with 24 ounces vegetable broth, ½ teaspoon salt, and ¼ teaspoon pepper. Stir to combine, then bring the mixture to a simmer. Cover the pot and reduce the heat to low. Let it cook for 10-15 minutes, or until the potatoes can be easily pierced with a fork. The simmering broth will fill your kitchen with warm, comforting scents!
Blend the Soup: Remove the pot from heat and allow it to cool for 2-3 minutes. Using an immersion blender, blend until smooth. Alternatively, you can transfer the soup in batches to a standard blender. Remember to remove the center cap from the lid and cover it lightly with a kitchen towel to let steam escape—this is key for safety! Filling the blender over halfway could lead to some messy explosions, so take your time here.
Heat with Milk: Pour the blended soup back into the stock pot (if using a standard blender) and return it to the stove. Over medium-low heat, stir in 8 ounces whole milk until it’s fully incorporated and the soup is heated to your preference.
Serve with Toppings: Ladle the warm soup into bowls and get creative with your toppings! Consider chopped parsley, crunchy croutons, shredded cheese, or even crumbled bacon to add texture and flavor.

Storing & Reheating
Store any leftovers in an airtight container at room temperature for up to two hours. For longer storage, pop it in the fridge where it will keep for about three to five days. If you want to freeze your Irish Potato Soup, transfer it to freezer-safe containers and store for up to three months. Reheating is simple; just warm it over low heat on the stove until heated through, about 5-10 minutes, stirring occasionally. Be aware that the texture may change slightly after freezing, but stirring in a splash of milk can help refresh its creaminess.
Chef’s Helpful Tips
- When sautéing, be mindful of the heat; if the vegetables brown too quickly, turn it down to avoid burning.
- Ensure the potatoes are cut into uniform sizes for even cooking—around 1-inch cubes work well.
- For a touch of gourmet, consider adding fresh herbs like thyme or chives while simmering.
- If you want a bit more flavor depth, roast the potatoes in the oven beforehand.
- This soup can be made a day in advance—as the flavors meld, the taste improves!
