St. Patrick’s Day Potato Leek Soup

Celebrating St. Patrick’s Day is blending that same sense of togetherness with a nod to Ireland’s beloved potato. This creamy potato leek soup honors tradition while adding a touch of Mediterranean flair for a cozy, satisfying family dinner.

Ingredients:
Recipe
(Serves 2-4 people)
- 4 large Russet potatoes, peeled and cubed
- 3 leeks, white and light green parts sliced
- 3 Tablespoons unsalted butter
- 3 Tablespoons olive oil
- 3 cloves of garlic, minced
- 4 cups vegetable or chicken broth
- 1 cup of half and half
- ¼ cup grated Parmesan cheese
- 1 tablespoon chopped fresh parsley
- Salt and pepper to taste
Instructions
- Prepare the leeks: Cut the leeks to the dark green part and discard the dark green. Slice the leeks lengthwise and slice into ½ coins. Add to a bowl of cold water, completely submerged. Let sit for 20-30 minutes. The dirt and sand will sink to the bottom of the bowl. Lift the leeks out with your hands and wash well in a colander to remove the residual dirt.
- Sauté: In a large pot, warm the butter and olive oil over medium heat. Add leeks and garlic. Cook until leeks are soft and fragrant, about 8 minutes.
- Add cubed potatoes and broth: Stir in potatoes and pour in the broth. Bring to a boil, then reduce to simmer for 45-60 minutes until potatoes are tender.
- Blend for creaminess: Use an immersion blender to puree the soup until smooth (or carefully blend in batches).
- Add the Italian touch: Stir in the half and half along with the Parmesan cheese. Season with salt, garlic salt, and pepper.
- Serve and enjoy: Ladle into bowls, drizzle with extra olive oil, sprinkle with fresh parsley or sliced green onion, and serve with crusty Italian bread.
