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. This is just the sort of "leftover soup" recipe I needed — I came across it on Yummly. Trying with leftover corned beef hash, chard from the CSA box, and leftover cooked white rice (so cutting down on the liquid a bit). Thank you for the inspiration and guidance on cooking times.

  2. Glad you have enjoyed the recipe. I couldn't say for sure since I haven't tried it with kale, but in general kale will be a little more bulky after cooking and will take a little longer to cook.

  3. if substituting kale for spinach would it be s straight out swap, time and quantity-wise? I've made this recipe with spinach many times. Some of us are vegetarians and so I use the Morningstar sausage crumbles (9oz) instead of sausage occassionally and we enjoy it equally as well.

  4. Kelly, you would also have to skip the carrot to make it phase one. There are some other good phase one lentils soups in the recipe index (left side.)

  5. If you took the rice out, would that make it phase 1???? I love lentil soup!

  6. Julie, so glad you liked it.

  7. really, really good! I wouldn't have made it if I didn't think that I would like it, but it still turned out to be a surprising amount of flavor for just a little bit of effort. I used no salt tomatoes and didn't add any salt for seasoning, and it was perfect!

  8. Yes the rice is not cooked. (iPhone, sorry for short reply.)

  9. Hi, just checking to make sure, you but the rice in uncooked, correct? And one hour in the crockpot is all it takes? Thanks!

  10. So glad you liked it. My brother has become obsessed with this soup, and he's made several variations. Your blended version sounds good too.

  11. I made the soup tonight. I used Turkey sausage as well but I pureed the lentil soup first, then added the sausage and 2 Tablespoons Gram Marsala. Wonderful on a cold winter evening!

  12. Allison, so glad you liked it!

  13. I put this together and let it cook in the crockpot while I was at work today – delicious! I used fresh italian goat sausage from the farmer's market and it was sooo good. Definitely making it again!

  14. Brandon, so glad you like it. I will have to try that Harmon's sausage. And I agree, this would be good with kale.

  15. We've made this three or four times already. Needless to say, we love it. I add some cumin and chipotle chili powder in with the spices. Try Harmon's own garlic chicken sausage. It's mild but adds great flavor. I also tried this soup with kale, and I prefer it. One of the best soups on the blog. Thanks, Kalyn!

  16. Christeen, so glad you liked it.

  17. I made a batch on the stovetop using some chipotle smoked sausage, and holy cow, it was just awesome! What a super recipe! I'm already looking forward to making it again.

  18. Marc, I think your version sounds great! Spike is usually sold by health foods, but any seasoning blend you like the taste of can be substituted.

  19. Delicious! We made this recently but had to make one change (can't find Spike, made up my own combo) and chose to use 1/2lb fresh chorizo and 1/2lb fresh chicken sausage instead of the packaged. Since I couldn't find Spike, I made up a combo of salt, fresh ground pepper, cumin, paprika, chili powder, and a little curry powder. I can't wait to make it again! Thank you.

  20. Susan, I'm especially glad to hear it was a hit with the kids. Good to know that frozen spinach is good in this recipe too; I wondered about that.
