Now that the weather is changing, it’s time for some soup recipes! We love making larger batches of soup on Sundays to have for lunches all week long. Potato and leek soup is one of our favorite soups to make. The potato creates a thicker soup that’s filling and the leeks add a boost of flavor. In the typical preparation of this soup, we’ve found that you lose a lot of the leek flavor when it simmers in broth for longer periods of time. By preparing the soup sous vide (“under pressure”), it captures and retains more of the flavor.

We’ve touched on sous vide cooking the past, but mostly in reference to preparing meats. While sous vide cooking is amazing for creating a perfectly cooked steak, it’s also great for all kinds of soups! We use the Anova culinary sous vide precision cooker. It’s compact and easy to use and fairly inexpensive. We also use a vacuum sealer, which is not essential, but very useful when preparing foods sous vide. We recently found one on Amazon that’s cheap and has reusable bags! The concept of sous vide cooking is that items are cooked in a constant temperature water bath with circulating water. Rather than simmering vegetables in broth and losing a lot of their flavor and nutrients, this method retains all of those flavors in the bag.

Once the vegetables have cooked through, all you have to do is simply pop everything into a blender (or you can use an immersion blender) and blend until smooth. We love using our Vitamix for soups like this, because it blends into a perfect velvety consistency. We top off the potato and leek soup with a little drizzle of olive oil and some fresh herbs for a filling and comforting lunch or dinner!
