Easy turkey and lentil soup that can be cooked on the stovetop or in the Instant Pot or crockpot. A great way to use leftover turkey or chicken!

Yes, I’m a little late on the whole leftover turkey thing. BUT if you’re anything like Fiance and I, you’re still working through that massive bird. We only had a 7 pound turkey, but we still have a drumstick, thigh, and this soup. And I’m truly impressed with this progress!

We’re moving out of our flat and heading back to the good ol’ US of A in about 12 days. That means we are eating leftovers and whatever is in our cupboards and freezer, and that’s about it. Inexplicably, I bought a ridiculous amount of split red lentils earlier this year with the idea of making an Ethiopian dish with them. Not only have I still not gotten around to making that dish, but I’ve since learned that just a little bit of lentils goes a long way. Oops.

What to do with leftover turkey

So, when thinking of ways to repurpose our turkey, I wanted to use up some of these lentils. A turkey and lentil curry just sounded a little to strange, and since I was making stock from the carcass anyways (which you should totally do!) I went with this turkey and lentil soup.

This soup is very simple and totally delicious. We also had leftover carrots and celery, so those went into the soup, too. Using the turkey to make the broth made this soup all the better and more wholesome. If you want to know how to make your own stock, check out this post. Just sub your turkey for the chicken! I made it just a little bit spicy and topped it with grated parmesan for good measure.

This soup is also on the lighter side to help you detox a bit after Thanksgiving wonderfulness and in preparation for even more holiday meals. Yay, holiday season!
