Instant Pot Smoked Sausage and Lentil Soup

A hearty yet wholesome soup packed with lentils, smoked sausage and diced vegetables. Easily made on the stovetop or in the Instant Pot!

I know, I really need to make something other than soup with lentils. What can I say, we are kind of obsessed!

We always buy lentils in bulk because if we’re not cooking them as a side dish, they’re getting tossed into a clean-out-the-fridge soup. Lentils are full of nutrients, but specifically protein, fiber and iron. All good things, especially when you’re on a restricted diet like myself.

It doesn’t hurt that our kids love them too. We made this cozy smoked sausage and lentil soup the other day and they demolished it! I was pretty darn proud of them.

I think you’ll love this soup because:

  1. It’s super easy to make
  2. It’s made with minimal ingredients
  3. It’s flavorful and filling
  4. It’s healthy and wholesome
  5. It’s dairy-free

Ok, that last one was for just for me. ?

It can be made on the stovetop OR the Instant Pot, the choice is yours. I personally went with the Instant Pot because I had to “set it and forget it” while I ran a few errands. #momlife

Speaking of errands, next time you’re browsing the aisle of the grocery store, make sure to grab some of this Cajun seasoning. This isn’t a sponsored post, I just really love McCormick’s gourmet spice blends. I’ve been grabbing them and using them a lot lately. So easy and they add SO much flavor to a dish.

If you can’t find it you can grab any generic cajun or creole seasoning.

Cook the soup on the stovetop or grab your Instant Pot and let it do all of the work. I highly recommend the latter!

The stock will thicken nicely, the vegetables will be nice and tender and the flavors will be popping without being overwhelming. Of course if you want more wow, you can add a ¼ teaspoon of cayenne pepper for some heat.

I hope you will love this soup as much as we do. Enjoy!

    1. It would be the same method, just on the stovetop in a large stockpot or Dutch oven. I generally simmer it all for 25 minutes. Hope that helps!

  1. I am so excited about this recipe !!!!’ I love in Montana and it is certainly brisk now so perfect soup for today . It’s a plus that you have the Dutch oven recipe as it’s my favorite thing in the world to cook with!!! I stumble across your site on Pinterest looking for a cleaning checklist which I still haven’t found because I got side tracked with all the yummy recipes.

  2. I have never tried lentils. Your recipe looks yummy. Is this spicy with the cajun seasoning, black pepper and 2 kinds of paprika? I don’t handle spicy very well. Would you suggest that I make an adjustment to the seasonings?

  3. I find the lentils take almost a hour to cook through, after 25 minutes they are still hard as rock??? Am I doing something wrong? Still delicious in the end, just take alot longer!!

    1. I’m sorry, I wish I knew. They shouldn’t have taken that long. I’m am trying to think of why they would have taken that long.

  4. 5 stars
    This soup was fantastic, and I don’t even love lentils! The lentils do take a lot longer than 25 minutes to cook, but the longer you simmer this soup, the better it tastes. Today was the first time I found your blog, and this was my first recipe. I’ll definitely be back for more! Thanks for a great recipe!

  5. I’m sorry, but I’ve never heard of paprika that isn’t ground. From the definitions I’ve looked at online, it appears to be defined as a powdered spice. Could you please explain what you mean by, presumably, “non-ground” paprika? Thanks

    1. I would cook on high 3-4 hours. I would probably brown the sausage first in step 1 then add everything to the slow cooker.

  6. 5 stars
    Wow – fantastic soup that my whole family including my sometimes finicky teenager!! Extremely flavorful and quite satisfying. We suggest serving with cornbread. Oh so yummy!!

    I made a half recipe of this in my instant pot, using turkey kielbasa, smoked paprika, and added chopped carrots for extra color, flavor and texture. My husband said, “You can make that again!”
