A few weeks ago I made this Crockpot Lentil Soup with Sausage, Brown Rice, and Spinach on a day when my brother Rand happened to be in Utah visiting for my dad’s 85th birthday party. Rand always likes to try out my leftover cooking experiments when he’s visiting, and he loved this soup so much that when he went back home he asked if he could have the recipe *before* it was posted on the blog.

I’m always in debt to Rand for the beautiful graphics he creates for the blog, so of course I was only too happy to send off the recipe by e-mail. Rand made the soup for friends in L.A. who also want the recipe now, so I decided I better hurry and get it posted!

If you’re a fan of making soup in the crockpot, this is a great recipe to cook on the weekend when you’re busy doing other things. But if you don’t have a crockpot, check the end of the recipe for instructions of how to make this on the stove.

How to Make Crockpot Lentil Soup with Sausage, Brown Rice, and Spinach:

(Scroll down for complete recipe with nutritional information.)

  1. Cook the diced onion, carrot, and celery in a little olive oil, then saute the veggies with the dried spices and garlic before you add it to the crockpot. I think this extra step adds a lot of flavor to crockpot soups.
  2. Cut up 3 pre-cooked sausages into bite sized pieces and add to crockpot. (I used  Aidell’s Artichoke and Garlic Chicken Sausage for my soup, but any type of pre-cooked chicken or turkey sausage will work. Use more sausage if you prefer, which will make the soup lower in carbs!)
  3. Then add canned tomatoes with juice, chicken stock, brown lentils, red lentils, and salt and fresh ground black pepper to taste.
  4. Cook that on high for about 3 hours, or until the brown lentils are soft and the red lentils are starting to dissolve.
  5. Then add 1/4 cup uncooked brown rice and 4 cups chopped fresh spinach. (I used Uncle Ben’s Brown Rice.)
  6. Cook that for about an hour longer.
  7. Then stir in 2 T balsamic vinegar, cook for about 15 minutes more and serve hot. This is good with parmesan cheese sprinkled over if desired.

I used a 3.5-Quart Crock-Pot Slow Cooker (affiliate link) for this recipe. I used Aidell’s Artichoke and Garlic Chicken Sausage. The soup would be amazing with homemade chicken stock, but if you don't have that use 4 cans chicken broth.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Using low-fat chicken or turkey sausage and low-glycemic ingredients like lentils and brown rice makes this Crockpot Lentil Soup with Sausage, Brown Rice, and Spinach a great choice for phase 2 or 3 of the original South Beach Diet. Lentils and brown rice are high in carbs for traditional low-carb diet plans, but there isn’t too much of either of those ingredients so you might be surprised if you check the nutritional information. (I haven’t tried it, but I’m guessing you could make a pretty tasty lower-carb soup with this recipe by using only lentils, adding more sausage, and leaving out the carrots and brown rice.)

  1. Delicious! My whole family (kids ages 3, 6, and 8) gobbled this up for dinner. I only had brown lentils, and used frozen chopped spinach, but otherwise followed as written. It was perfect for a chilly winter evening.

  2. Nicole, thanks for the nice feedback about the recipes. I like your variations for this (especially the hot sauce – great idea!)

  3. I made this today, too, and it turned out great! I used Penzey's jarred broths and did 2 cups of ham broth and 3 cups of chicken. I added a tiny bit of heat with a dash of cayenne, too.

    Your Moroccan lentil stew is one of my rotation meals that I always cook to freeze since it freezes so well. I love the red lentils in that, and I am always looking for them in other recipes.

    My husband and I both enjoy your recipes– I can't think of one that we've tried that we didn't like.

  4. Michele, I bet that's good. My brother Rand is at my house right now and he thinks it sounds good too. Thanks for sharing.

  5. Hi Kayln – Faced with a large amount of stock and leftover turkey after the big day, I decided to make this soup with leftover turkey. It turned out great! I made it on the stovetop, and added the turkey about 10 min or so before the balsalmic vinegar. If I were doing it in the crockpot, would probably add it 30 min – ? Anyway, I'll probably try it with the sausage another time.

  6. Paz, I never met a lentil soup I didn't love. It's my favorite soup ingredient by far!

    Susan I agree about the brown rice. I love Uncle Bens brown rice; it's a long-grain rice and cooks more quickly than some.

  7. This soup looks amazing! Love that you used brown rice, I love it but it often gets overlooked.

  8. Yum! I'll have to try this recipe. Recently made some lentil soup.


  9. If you don't have a way to brown the veggies, just put all the ingredients in together. It will still be fine, I just think sauteeing the veggies with the herbs brings out the flavors.

  10. This looks delicious. I don't really have access to a stovetop.. any suggestions for making it delicious without frying the veggies first?

  11. This looks delicious Kalyn. I see why Rand wanted the recipe!

  12. I know I've really made something good when my brother requests it. This sounds delicious!

  13. this soup looks wonderful. We don't eat processed meat so I might just use chicken or turkey here. Also, I've never used thyme in my cooking before but I see it now on all the cooking blogs I read – it must be "herb of the season" so I might just give it a try and see if I like it.

    Thanks for the great recipes!

  14. Stephanie, so glad the recipes are working for you (and for your husband too sometimes!)

  15. This looks really good! I am on SBD, but hubby isn't (though he should be), and it's hard to find diet dieshes he likes; he's a real meat-and-potatoes man. I may have to leave out the spinach and just add it to my bowl.

    However, he LOVED your double berry jello salad, enough so that he didn't eat any more of his canned jellied cranberry sauce after eating mine!

    I also made your pumpkin cheesecake pie for me, as hubby wanted a pecan pie, and I used the crushed pecans crust as suggested in the comments. Scrumptious! I had enough filling for two pies, and I've brought one to work to LEAVE, as I ate the entire other pie by myself. I can't DO that anymore, but it was wonderful while it lasted.

    Thanks so much for these recipes–it's making my life a little easier.

  16. Sometimes I think I could live on lentils if I had plenty of other ingredients to flavor them! Glad people are liking the soup.

  17. What a great way to transition into December! I love lentil soup, and my crock pot!

  18. Brown rice and spinach in combination with the lentils are a great idea. I did a similar soup with chick peas.

  19. We love sausage and lentils here! I'll definitely be making this soon. Thanks Kalyn!
