Slow Cooker Potato Leek and Cheddar Soup
Potato Leek and Cheddar Soup is a deliciously kicked up version of the original potato and leek soup, which is one of those dishes I am pretty sure everyone has experienced in their lives at least once.
I doubt I would be able to count the amount of times I have had it in my thirty years.
Growing up we had it ALL the time. It is both simple and delicious, and for me, it is basically the epitome of comfort food.
From now on, If it’s cold, rainy and miserable outside, you know I will be having some potato, leek and cheddar soup (or at least would like to be).
How To Make Your Potato Leek and Cheddar Soup Even Better
Now, I have made potato and leek soup in every way imaginable (obviously Potato Leek and Cheddar is now my favourite 🙂 ).
In fact, following thanksgiving, I made some with homemade broth from smoked turkey scraps (use everything guys!) - OMG, if you ever smoke a turkey for thanksgiving (or any other occasion) - be sure to make some broth with the bones, followed by some potato and leek soup, coz that my friends, is something else.
Over the years, I have noticed there tends to be a bit of a fierce argument when it comes to whether you are in the chunky or smooth camp (in regards to potato and leek soup).
For years, I was firmly in the chunky soup camp, I am pretty sure that's what my mum made growing up - and that's what you stick to right? Mum knows best 🙂
Unless you are married of course - and then apparently his mum knows best...Hubby is in the smooth soup camp (yep, his mum is to blame for that). And to get the level of compliments I need these days, I have to make things the way he had it growing up: so we are going smooth with our potato and leek soup (plus it turns out it’s easier for the little ones to eat like this - but he doesn’t need to know that).
I did change it up a bit. I had a busy day, so popped all the ingredients into the slow cooker, and let it do it’s thing, making it a really simple leek and potato soup.
I also added some cheddar, because for some reason when it’s cold, cheese is something I need, and Costco had Dubliner, so how could I possibly say no?
Potato Leek and Cheddar Soup was born, and there is no going back now, it's a keeper 🙂

It was great. Really yummy. I suggest you try it! And, if you happen to have some homemade turkey bone broth, use that to give it an even bigger kick:)
I have been using the Instant Pot as my slow cooker for the last couple of weeks, and it has been great.
Slow Cooker Potato Leek and Cheddar Soup
Ingredients
- 2 tbsp unsalted butter
- 3 whole leeks cleaned and thinly sliced, white and light green (reserve 2 tbsp for serving)
- 1 tsp kosher salt
- 4 cloves garlic
- 4 sprigs fresh thyme
- 1 ½ tsp dried oregano
- 2 bay leaves
- ¾ cup white wine
- 5 cups vegetable broth make your own
- 4 medium gold potatoes peeled and diced, I used yukon
- 1 ½ cups cream or half and half
- ⅓ cup grated cheddar cheese
- extra leeks and cheese for topping
Instructions
- Melt the butter in a skillet over medium heat. Add the sliced leeks (remember to keep some aside for serving) and salt and sauté until soft. Add the garlic; saute for 30 seconds and then remove from heat
- Pop the leeks and garlic into the slow cooker. Add in the thyme, oregano, bay leaves, white wine, broth, and potatoes and give it all a good stir
- Set the slow cooker to low for 5 hours
- After the 5 hours, add in the cream. Stir to combine and then puree the soup until smooth. If you have a stick blender then use that right in the pot, otherwise blend in batches in a regular blender (remember the soup expands when it is hot, so don't put too much in there)
- Pop everything back into the slow cooker and set to low for another 30 minutes
- After 30 mins, stir in the cheese and serve with the extra leeks and cheese

I learned to make potato & leek soup from my Irish-born hubby (Co. Down). His version was very good, but I think your version is even better! And of course, everyhing is better with Dubliner cheese!
Your recipe was so rich & flavorful; I really enjoyed it. I think it was the addition of the homemade veggie stock.
I also eat soup nearly every day, including during the summer (I live in Arizona). Comfort food at its finest!
Donna says
Definitely yes to the Dubliner cheese, it makes everything better 🙂 Well I am glad you enjoyed my version as much as (if not more) than your hubbies 🙂 We literally had this over the weekend as it was pouring down with rain so a big bowl of comfort was definitely required!! Thanks for popping by
Annie says
Curious if you have ever frozen this?
Donna1 says
Hey Annie, I have frozen it. It worked out ok. It wasn't as good as fresh from the pot soup, but it was definitely still enjoyable.
Marie-Pierre Breton says
I love leeks sooo much, but just never know what else to do with them then a flamiche or chicken pot pie. Now I know! This soup looks unctuous and sooo comforting, and the cheddar touch to bring it to another level! Great soup!
Donna1 says
It is seriously delicious, and so so easy. But I have to say I am totally craving a nice chicken pot pie now that you have mentioned it 🙂
andrea says
this potato look soup looks incredible and oh so rich, i wonder if I can make this dairy free and it still would be as tasty. and love that you can make it in the slow cooker.
Donna1 says
Oh I am sure you could sub with dairy free alternative. I am always using leftover nut milk in my soups, and they taste delicious!
Anne Murphy says
Not only does it love lovely and delicious, but you do it in the slow cooker? Wonderful!
Donna1 says
Oh I know - anything that can be made in the slow cooker gets a big thumbs up around here!

Donna1 says
Yay, thanks Oana 🙂 Potato and leek has definitely been one of my favourite flavour combos since I was little - the cheddar just takes it to the next level!

Donna1 says
Haha I wish 🙂 The one year old has to be trapped in his highchair or napping for me to get any photos taken - we have had many 'incidents' - those involving soup are not pretty 🙂
