How soon do you start to make New Year’s resolutions? Do you start to think about them a week before, or a month before?

First, let me just tell you how much I hate New Year’s Resolutions. I hate them. That’s how much. Too much pressure. When I decide on a resolution, I have to do it right there and then. If I wait until the 2nd of January, it won’t happen. Ever.

For that reason I decided to stop holding off on a few things that I had in mind for 2013. One of them was this; Savory Sundays. Lemme tell you why. I have so many recipes and photos in the queue that my hard drive is about to crash. Most of them are savory dishes. You do know that we don’t eat Rocky Road Fudge Brownies for dinner, right? I mean, I do, but I share this home with a few others and they kinda want something savory before diving into the brownies.

Right now, at this very moment, I am making this Slow Cooker Leek and Potato Soup, again. We have had this 3 times in the last 2 months. If you hadn’t noticed, I use my slow cooker a lot. You can see the evidence here and here. For me it really is the only way to get other things done. Come 10 am I just start to throw things into the slow cooker pot, turn it on, cross my fingers and pray that it will be as good as I imagine it. Most of the time it is.

Now go and start peeling some potatoes so you can serve dinner by 5ish tonight.

Have a very happy Sunday!

    I have made this 6 or 7 times now. It is my go to soup! Only change I make is not to puree it. I tried it the first time and just prefer it as is. So happy I found this recipe.

  2. Kris

    i am confused. The instructions say to purée the soup, but in the picture it looks like there are chunks of potatoes. Is it necessary to purée?

  3. Aleksandra

    I got so excited about your blog – my fellow Macedonian! Great job! I actually found it through an email from Oprah’s team which recommended 6 best crock pot recipes for winter (Feb 26 I think). Kudos.

    About this dish – I think I used too many leaks (had frozen and cut from Trader Joe’s) so it wasn’t a hit. How did yours end up orange/red? Mine was yellow-ish. I ate 2 cups but my hubby and the baby (8.5 months) weren’t fans. Any recommendations in ways to tweak it (other than less leeks)?

    Hope you have other crock pot recipes coming. I’ll definitely try more…my resolution is try the new dishes at least once per month. Doing well on that resolution so far.


    1. Hi Aleksandra!! SO glad you found me!! 🙂

      My soup is always a bit orange – I think that’s more to do with the 3 carrots that I add to it. Was it the flavor of the leeks that they didn’t like? If that’s the case, use only one large leek. I have never used frozen leeks, and since I don’t know how much is in one bag, I couldn’t tell you if you might have used too much. The taste of leek should be subtle – not overpowering – but still there. 🙂 I hope this helps! Let me know!!

      It wasn’t a hit at our house either. The celery overpowered the other flavors. I tried it with and without the parsley and it wasn’t good. We experimented with adding corn, soy sauce, and milk (separately and at the same time). Only the corn helped. Finally, on a whim, we tried coconut milk. It was pretty good, but not the same soup at all. In all, this is the first 1 star rating I’ve ever had to give. We won’t make this one again.

  4. Karen

    The potatoes didn’t cook in the 4hrs on high. I’m about to dump it into a soup pot to try and salvage this. Maybe it’s my crock pot? I don’t think so. I use it all the time

  5. I love finding new recipes for my slow cooker. This sounds really delicious. I like to use it on days when I’m really busy and can just throw everything in in the morning and come home to a lovely meal later on.

  6. I’m about to pick up my daugther now, but before that I need to get leeks for this recipe. I REALLY love leeks and potatoes together (I make gratin) and tonight is pasta, so I’m making this on the side! So easy but delicious and I know it!!! Thanks, Kate! I should have checked this post earlier when I saw the pic on IG…. I’m always running behind on posts… =P

  7. I was wondering how I missed this, then I realized you weren’t in my reader – gasp! All fixed now! This looks perfect & I can’t wait to try it! Love your photos too!!

  8. Savory Sundays is a mighty fine idea. I find soups to be so challenging to photograph and you’ve done such a fine job. Funny thing I used leeks today to in pancakes and this soup looks absolutely delicious!

  9. I love leek and potato soup but have never even once thought of making it in the slow cooker! This looks absolutely delicious.

    You know, you and I are opposites. My files are bulging with recipes too, but I usually talk about the savory dishes and don’t spend too much on sweet stuff. I’m so glad you gave us a peek at your dinner table because this one’s a keeper.

  10. This soup looks so cosy! (Love your serving cups!)

    I don’t think about New Year’s resolutions until never. They’re wily little things which start off with a coy tip-of-the-hat- but as soon as you turn around they pick your pocket, steal your good intentions, and leave you feeling sad and used.

    Much better to eat and drink in merry moderation all year ’round. 😉

  11. This is one of my favorite soups! It reminds me of when I first tried it in a pub in England with my in-laws. They were shocked that I hadn’t eaten a leek before! Now I make it a few times a year.

  12. I seem to get all caught up in baking and other projects and let dinner slide. Great idea to break out the slow cooker…and Bill would be quite happy with this delicious soup!
