I’m watching the 75th Golden Globes as I write this. How about that Oprah speech, right? If you missed it, I recommend you YouTube it ASAP! I’m grateful, as a woman, to have that powerful, eloquent voice speaking for me. I will admit that the tears were rolling! But I digress…

Let’s talk about this soup.

Food in bowls is the theme around here in January. We’re going for wholesome, hearty and comforting. Bonus points for silky and creamy!

This classic leek and potato soup epitomizes all of that. And it doesn’t hurt that it’s one of Jack’s favorites, which means one less dinnertime struggle!

Although actually most creamy vegetable soups are alright by him… I suppose they probably remind him of the purée days :).

Leeks and potatoes on a cutting board

Leek and potato soup is ridiculously simple to make and is ready in under 30 minutes. Just sauté some leeks and onions, add broth and potatoes and simmer till tender. Blend, and voilà! Glorious leek and potato soup.

I often make a double batch of this and freeze some for later. If you do that, I would recommend freezing it before adding the cream because cream-based soups tend not to freeze very well. They can separate or take on a grainy texture.

Once thawed and re-heated, you can give it a quick blitz with the immersion blender if necessary, and stir in a couple tablespoons of cream and it will be lovely and silky again.

I recommend slicing the leeks in half lengthwise before chopping them, mainly because this makes it easier to clean them properly. Dirt tends to get trapped in the inner layers.

There’s something about buttery sautéed leeks that just really does it for me. If you love them as much as I do, check out this recipe for my favorite leek and bacon quiche.

Or if you’re all about the creamy soups right now, like we are, here are a couple of our favorites:

  1. I forgot to mention in my previous comment that I used home made chicken stock, not store bought, which always seems to enhance the flavor of soup.

  2. This soup is delicious! So quick and easy and perfect for a gloomy, chilly wintry day. I followed the recipe exactly, and may top it with some crumbled bacon to make my husband happy. Immersion blender makes it so silky and smooth.

    A cup of creamy soup is such a wonderful way to start a meal. Potato leek is one of my favorites. I especially like it as a start to a meal of beef and mushrooms.

    Potato leek is such a classic, and so lovely at this time of year! Spending time in the kitchen cooking and baking is all I want to do! Oh or curling up on the couch and watching award ceremonies. That’s pretty fun too. Have a great week.
