Ingredients
2 tablespoons unsalted butter
3 large leeks, cleaned and sliced (white and pale green parts only)
1/2 cup white onion, diced
5 cups low-sodium vegetable broth
3 medium russet potatoes, peeled and diced
1 1/4 teaspoons salt
1/2 teaspoon garlic powder
2 bay leaves
1/2 teaspoon dried thyme
1/2 teaspoon black pepper
1/2 cup plain Greek yogurt
1/4 cup warm water
Fresh chives and extra thyme for garnish
Instructions
Melt butter in a large pot over medium heat until it begins to froth.
Add sliced leeks and diced onions to the pot and sauté gently until softened without browning.
Stir in the diced potatoes, garlic powder, salt, thyme, and black pepper, cooking for another 2 minutes.
Pour in the vegetable broth and add the bay leaves.
Bring the soup to a boil, then reduce heat and simmer for 20 minutes, or until the potatoes are tender.
Remove the bay leaves and use an immersion blender to process the soup until completely smooth.
Whisk the Greek yogurt with warm water in a small bowl to temper it, then stir it into the warm soup.
Serve hot, garnished with fresh chives and extra thyme.
Notes
Ensure you wash the leeks thoroughly, as dirt often hides between the layers. To temper the yogurt, always mix it with a little warm liquid before adding to the hot soup to prevent curdling. Store in an airtight container in the refrigerator for up to 4 days.
