Step 1

If serving with bacon: Preheat the oven to 400 degrees F and prepare according to this guide for Baked Bacon. Crumble or dice and set aside.

Step 2

Heat olive oil in a Dutch oven or similar medium/large saucepan over medium heat. Add leeks and potatoes cook, stirring occasionally, until the leeks begin to soften, about 2 to 3 minutes. Add the garlic and cook until fragrant, about 30 seconds. Add the broth, asparagus, salt, and pepper. Bring to a boil, then reduce heat and simmer until the vegetables are tender, 10 to 15 minutes.

Step 3

With an immersion blender, puree the soup until smooth. (You can also carefully transfer it to a blender or food processor in batches and blend it that way. Be careful as hot soup tends to splatter!) Return the blended soup to the pot and let cool a few minutes. Stir in the Greek yogurt, then season to taste with additional salt and pepper. Remember that if you are adding the bacon on top, it will also be salty, so be careful not to overdo it.

Step 4

Serve hot, topped with crumbled bacon, a sprinkle of fresh chives, and an extra dollop of Greek yogurt as desired.
