Slow cooker lentil and ham soup is a cheap and cheerful slow cooker lentil recipe made with pantry staples. This recipe contains affiliate links.
I am a true believer in the slow cooker, it's a handy tool for every kitchen. Don't get me wrong, there are certain foods that work better with a long braise in the oven or are better suited for the stove top, but on the other hand, there are some dishes that are just made for the slow cooker.
Enter this slow cooker lentil soup with ham. There is no pre-cooking required–all you need to do is add all of the ingredients to the slow cooker, and let the gentle heat do all the work.
There is no need to precook or soak the lentils, that's the beauty of slow cooker lentil recipes! I also love making congee in the slow cooker for another dump-and-go slow cooker recipe.
This is a go-to recipe for those busy cold, winter days. Or for those days when you just don't really feel like cooking. A little chopping is all that is required.
This slow cooker soup is definitely inspired by French cuisine. It starts with a mirepoix (a combination of onions, carrots and celery). You could throw in leftover ham (if you have some on hand), but I usually just buy the smoked ham when it’s on sale at the grocery store. All that’s left to do is adding some lentils, herbs and the liquid.
Which herbs should I use in slow cooker lentil soup?
Generally speaking, herbs that are sturdier work best in slow cooker recipes. I'd generally reach for dried herbs when a long cook time is involved. Rosemary is my-go in a recipe like this slow cooker lentil soup with ham, but oregano or thyme would also be great.
When the soup is done, I finish it off with a couple of handfuls of chopped fresh spinach (they add nice colour to the otherwise brown soup) and a hit of cider vinegar to brighten the flavours. Definitely don't skip the vinegar at the end-though you could also use lemon in a pinch.
I also stir in olive oil at the end for a smooth finish and mouthfeel, it’s a perfect finishing touch.
This is a cozy soup recipe that I would 100% serve with some cheesy garlic bread. Hello, winter comfort food!

It was delicious. I discovered to my surprise that I was out of rosemary as I was putting it all together, so I used Italian seasoning.
One little thing is that a serving can mean anything to anyone, so it would be helpful if you were a little more specific on the amount in your list of nutrients.

Thanks Lynne, so glad you enjoyed this!

Thank you!

I only had fresh rosemary so used that and the soup is great! Oh, and I grated one large carrot (instead of chopping) since my husband is not a big carrot fan.

This soup was delicious! I substituted smoked Polish sausage for ham and used all chicken broth instead of water. I increased the veggies, too, because I like a heartier soup. I also cooked it for six hours in the crockpot instead of four. Very good!
Louisa Clements
Thank you Kimberly! I bet the Polish sausage was delicious in here and extra veggies is always a win in my book! I’m glad you enjoyed this recipe. :)

Hi Louisa
Found that I needed to cook the soup longer. Lentils were not soft. Otherwise great taste. Thank you for the recipe.

Thanks Lisa! Lentils can be tricky sometimes and can require different amounts of cooking, I’m glad you enjoyed the recipe!
