Instructions
In a large pot, melt butter over medium heat. Once melted add sliced leeks and celery, cooking for 8-10 minutes until softened.
To the pot add minced garlic, dried thyme, coarse salt and a couple turns of ground pepper. Stir and cook for 2 more minutes.
Add the potatoes and broth, stir and bring the soup to a boil over high heat. Once boiling, turn down to medium-low heat and simmer for 20-25 minutes until potatoes have softened.
Remove the pot from the heat and stir in the greek yogurt.
Use a hand blender to blend the soup right in the pot. Or transfer 2 cups at a time to a stand blender to blend until smooth then return the soup to the pot. Adjust seasoning to your liking with more salt and pepper.
Topping
Pre-heat the oven to low-broil. To make the topping, mix the chopped leeks and prosciutto with olive oil and place on a baking sheet. Broil for 5-7 minutes until prosciutto is crispy.
Notes
A quick note when you go to reheat the soup, since it's quite thick add a splash of broth or water and then reheat on medium-low.
