  • 1 pound lean ground turkey (we like a combination of white & dark, about 93% lean...feel free to use extra lean turkey breasts)
  • 1 teaspoon garlic powder
  • 1/2 teaspoon black pepper
  • 1 teaspoon sage, ground
  • 1 teaspoon onion powder
  • 1 teaspoon red pepper flakes (more or less to taste)
  • 1 teaspoon dried oregano
  • 1/2 teaspoon cayenne pepper (more or less to taste)
  • 1 tablespoon extra virgin olive oil
  • 1 small yellow onion, diced
  • 1 stalk celery, diced
  • 1 clove garlic, minced
  • 2 medium russet potatoes, and cut into 1" cubes, optional is leaving on the peeling (we prefer organic potatoes for this recipe, when on sale of course)
  • 1/2 teaspoon black pepper
  • Sea or Kosher Salt to taste
  • 1/4 teaspoon cayenne pepper
  • 4 cups chicken broth, fat free, low sodium
  • 2 cups milk, 2% milk was used (use milk that has some fat)
  • 1 cup baby spinach, rinsed and chopped


  1. NOTE: It's very important that the milk NOT be added until the very end of cooking as stated below. For best results, in a small mixing bowl combine 1/2 cup liquid from the slow cooker to the 2 cups milk before adding milk to the slow cooker.
  2. Combine the sausage ingredients in a medium bowl, make into 1 1/2” size meatballs, cover and keep refrigerated while preparing the other soup ingredients.
  3. In a small skillet, add extra virgin olive oil, turn to medium low heat and sauté diced onion and celery for approximately 5 minutes, or until tender. Add to the slow cooker: sautéed onions and celery, along with garlic, potatoes, herbs, spices and chicken broth; stir all the ingredients to combine.
  4. Add turkey sausage meatballs to the soup mixture. Cook on low 6-7 hours or until meatballs are done. Just before turning off the slow cooker, add milk and spinach and allow to cook just until spinach is wilted and soup heated through, about 5-10 minutes. 4-6 quart slow cooker recommended.
  5. This recipe is featured in our cookbook, Skinny Ms. Slow Cooker.

    I'm making this one for dinner tonight. I will let everyone if we like it 🙂

    • Skinny Ms.  September 6, 2012

      Tammy, Can't wait for your review! 🙂

  2. Tammy Tidwell Jones  September 15, 2012

    It was pretty good. It has a bite to it 🙂

  3. Jen  September 18, 2012

    I made this – my milk curdled after only 4hrs of cooking. So I removed the sausage and potatoes and poured the soup into a blender. I managed to salvage the soup, but then my meat was undercooked. I would definitely do this differently next time.
    If at all.

    • Skinny Ms.  September 19, 2012

      Jen, Did you use skim milk? The milk needs some fat otherwise it will curdle.

  4. Amy  September 19, 2012

    My milk curdled as well…any tips to prevent or is this recipe a bust?

    • Skinny Ms.  September 20, 2012

      Amy, You may need to use whole milk. I used 1% with no problems but whole will work.

  5. Samantha Melchert  September 23, 2012

    3.5 hours in and my milk curtled! I'm going to salvage my soup by straining out the meatballs and potatoes and adding them to fresh broth on the stovetop minus the milk. What substitution can be made for the milk in this recipe so curtling doesn't happen??

    • Skinny Ms.  September 23, 2012

      Samantha, What percentage of fat was your milk? Skim milk doesn't work…regular milk was used in this recipe.

  6. Melanie  September 25, 2012

    I didn't see the comments before putting into the crockpot, but I wondered about the milk. And…mine has curdled also. I wonder how it would affect consistency and flavor to put the milk in the last hour of cooking. Disappointed.

    • Skinny Ms.  September 26, 2012

      Melanie, 🙁 I've made this recipe numerous times and it has never curdled. I did change the recipe to add the last few minutes of cooking time.

  7. Wendy  October 1, 2012

    Normally, I would just throw everything in the pot and not read the directions. I'm glad I took the time to read them. If you follow the directions and put the milk in right before serving, you get a delicious soup (reminded me of zuppa Toscana). I think would prefer the turkey to be browned a little so next time I will do that before adding the meatballs to the crockpot.

    • Skinny Ms.  October 2, 2012

      Wendy, Thanks so much for the feedback!

  8. Kathie  October 17, 2012

    This recipe looks yummy. Do you think it would work if I substituted soy or almond milk for cow's milk?

    • Skinny Ms.  October 17, 2012

      Kathie, Sure, or coconut milk. Of course the taste won't be exactly the same but if you're used to not drinking cow's milk…should work fine! 🙂

  9. nanette  October 17, 2012

    Try canned evaporated skim milk. i have good luck with it, has a thicker consistency and no fat – hold up pretty well when cooking, although I wouldn't add it at the very begining…

  10. Jen  October 17, 2012

    I made this a second time – both times I used 2% milk but the first time I added it in the beginning and it curdled. So this time I added the milk about half an hour before eating and it worked much better. I do love the flavour of this soup

  11. Cheryl Burppo  October 17, 2012

    This sounds so yummy. But I can't have milk. Is there something else I can use. I can use silk. Would that work.

  12. Jennifer  October 17, 2012

    The milk could of curdled if it was to cold when added to the soup. To solve that problem is to add some of the soup mixture to the milk to bring up the temperature of the milk & then add milk to soup.

  13. Neds  October 17, 2012

    Is the meat supposed to be plain ground turkey with the additional ingredients or sausage?


    • Skinny Ms.  October 18, 2012

      Neds, Plain ground turkey with the ingredients listed in the recipe.

  14. Wendy Yurett  December 21, 2012

    The ground turkey plus the spices equals sausage 😉

  15. catabc3  January 7, 2013

    I only had sweet potatoes, so I chopped on huge one up into the 1 inch pieces. Do you think that will turn out alright?

    • Skinny Ms.  January 8, 2013

      Catabc3, It will be a totally different taste but should be fine! How’d it turn out?

  16. Tracy  January 18, 2013

    I am making this right now.. I didn't read the comments beforehand since i pulled the recipe from the cookbook. I used Non-Fat milk and I am at the four hour mark and so far no curdling here's hoping but it is very thin I am guessing that is the Non-Fat milk? And we didn't put the cayenne pepper in it since our baby will be eating it as well. But it smells amazing!!!!!
