I first made this Crockpot Lentil Soup with Sausage 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 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.

What ingredients do you need?

How can you make this a lower-carb soup?

There’s not a lot of lentils or brown rice in this soup, so check the nutritional information and see what you think. But if you want a soup that’s even lower in carbs, just use a bit more sausage and switch out the lentils and brown rice for about 1 cup frozen cauliflower rice. I’d add the cauliflower rice towards the end of the cooking time.

How to Make Crockpot Lentil Soup with Sausage 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.
  3. (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!)
  4. Then add canned tomatoes with juice, chicken stock, brown lentils, red lentils, and salt and fresh ground black pepper to taste.
  5. Cook that on high for about 3 hours, or until the brown lentils are soft and the red lentils are starting to dissolve.
  6. Then add 1/4 cup uncooked brown rice (or cauliflower rice) and 4 cups chopped fresh spinach. (I used Uncle Ben’s Brown Rice.)
  7. Cook that for about an hour longer.
  8. 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.

Notes

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 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. (If you want a version that’s even lower in carbs, use more sausage and replace lentils and rice with about one cup of cauliflower rice.)
