Slow Cooker Broccoli Cheddar Soup

This post may include affiliate links.

Broccoli cheddar soup ranks high on our list of favorite comfort foods. With each bowl chock-full of rich and creamy goodness, the soup is simply irresistible. Problem is, most recipes don’t go too easy on the waistline. Many conventional recipes call for high-fat ingredients like butter and cream. Likewise, store-bought versions usually carry a boatload of preservatives and sodium. Well lucky for you, here at SkinnyMs. we’ve brought you a full-flavored, lightened up version of the real thing. Our Slow Cooker Broccoli Cheddar Soup is nothing short of 100% decadence, and better yet, it won’t sabotage your waistline!

A Slimmer Version of the Savory Classic

Our Slow Cooker Broccoli Cheddar Soup is pure comfort with each bowl chock-full of rich and creamy goodness

The main focus of all of our recipes is to cook with whole foods, and this one is no different. Our lightened-up broccoli cheddar soup features fresh broccoli and other “real” ingredients. This differs from the to-go packages or canned soups you’d find in grocery stores.

Our revamped soup packs in all of that cheesy flavor you dream about, without weighing you down with fat and calories. Nothing beats curling up with a big bowl of this belly-warming soup. Plus, knowing that it contains nothing but quality ingredients only makes things better.

The Magical Wonders of the Slow Cooker

You’ll need a slow cooker for this recipe, and we must admit that this awesome appliance is a real game-changer. Slow cookers use long, low-temperature cooking, ultimately bringing out the richest version of each ingredient’s flavor. Not to mention, many cooking methods destroy the nutrients in ingredients due to rapid cooking on high heat, but using a slow cooker actually preserves them! Lower cooking temperatures and a more gradual heating process helps maintain all those feel-good vitamins and minerals your body wants!

The Stars of This Scrumptious Soup

Our clean-eating recipe proves that healthy soups can still taste irresistibly indulgent if they contain fresh ingredients, free of preservatives. Of course this recipe spotlights broccoli. It recommends using an entire pound of frozen broccoli, thawed and chopped.

One of the world’s healthiest superfoods plays such a big role in this recipe. That said, our savory soup certainly delivers a bunch of feel-good health benefits. We could honestly go on and on about the health powers of broccoli, but for time’s sake, we’ll just comment briefly on its nutrient-rich profile.

The nutrient-powerhouse is packed with vitamins, minerals, fiber, and bioactive compounds. It contains potent antioxidants to boost immunity and fight off disease. Meanwhile, its bioactive compounds can reduce inflammation and defend your body against cancer. If that’s not a reason to savor each and every delicious bite of this soup, we don’t know what is!

Next, our recipe calls for whole-wheat flour, just a few tablespoons. Nutrition-wise, this ingredient beats regular flour because it contains four-times more fiber than all-purpose flour. Meanwhile, it packs in more potassium, zinc, and magnesium than its counterpart.

Our recipe subs low-fat milk, organic preferred, in for regular milk. With its lower fat content, this alternative shaves off a chunk of calories while still creating that creamy consistency. Our savory slow cooker soup calls for a few more clean-eating ingredients you can feel good about. These include olive oil, chicken or vegetable broth, and of course, shredded cheese.

Your Waistline Will Thank You!

This healthy spin on an all time classic will provide you with all of the cheesy flavor you love, minus the extra fat and calories!
Prep Time10 mins
Cook Time6 hrs
Total Time6 hrs 10 mins
Course: Soup
Cuisine: American
Keyword: Slow Cooker
Servings: 6 people
Calories: 360kcal


  • 3 tablespoons whole wheat flour or white whole wheat
  • 1 cup low-fat milk organic preferred
  • 3 tablespoons olive oil
  • 4 cups chicken broth or vegetable broth, low sodium preferred
  • 1 pound broccoli frozen, thawed and chopped
  • 3 cups cheddar cheese shredded, skim not recommended for this recipe, please buy the block and shred yourself to avoid waxes
  • 1 garlic clove minced


  • In a frying pan, heat your oil, but don't let it get so hot it smokes. Using a whisk, whisk in the flour a little at a time so that the flour and oil mix well and start to bubble, and become golden in color and fragrant.
  • Slowly pour in the milk in a steady slow stream, whisking the whole time until a cream is formed. Follow with the chicken or vegetable broth until fully incorporated and then remove from heat.
  • Pour the mixture into your slow cooker and add the thawed broccoli. We use the frozen broccoli because it seems to hold up better in a slow cooker than the fresh variety. But you can certainly use fresh broccoli florets as well. Add salt to taste, black pepper and garlic, stir to combine.
  • Cook on low for 4-6 hours, or until the broccoli is completely cooked. Stir in the cheese, 1 cup at a time, allowing it to melt completely before adding the next cup of cheese.
  • Puree the soup in the blender in batches, filling halfway each time. A hand blender (immersion blender) will also work. Be sure to scrape any of the remaining cheese from the bottom of the slow cooker into the soup to blend well. Blend as little or as much as you like until desired consistency is achieved, i.e. some prefer a smoother and some prefer a chunkier soup .

  1. Crystal  January 30, 2012

    I may have the dumbest question ever – if I were to substitute the flour listed for white whole wheat flour, is that bad? Is it roughly the same?

    This recipe looks yummy!

    • Skinny Ms.  January 30, 2012

      Crystal – In this particular recipe, it would be fine. Enjoy!

  2. Peggye  June 9, 2012

    You could make this with vegan cheese and cut out all the cholesterol.  It only has 90 calories for a quarter cup.  It does have sodium, but when you want cheese soups it's a great alternative.  We have our favorite kinds.  We only use vegan cheese now, and you can't tell the difference.

  3. Stacy  August 12, 2012

    Great on a cool day or when you just don't want something heavy to eat.

  4. Charna Scarpati  September 13, 2012

    What if you don't have whole wheat pastry flour, is there something else I could use?

    • Skinny Ms.  September 14, 2012

      Charna, Cornstarch, whole wheat flour or white whole wheat flour will all work in place of the pastry flour.

  5. Robyn  October 15, 2012

    What could I replace the flour with to make this recipe gluten free? Would brown rice flour work?

    • Skinny Ms.  October 15, 2012

      Robyn, I think brown rice flour should work fine.

      • Shannon  January 2, 2013

        Cornstarch is gluten free

  6. Shannon  October 16, 2012

    If you use an extra sharp cheese, you can get by with using less. I also use Cabots reduced fat sharp and extra sharp cheeses in recipes such as these.

  7. Karen Benschoter  October 16, 2012

    What would 2% cheddar do to this point-wise? I’m on the new WW Points Plus system.

  8. Skinny Ms.  October 17, 2012

    Karen, We used 2% when calculating the data.

  9. Amanda  December 30, 2012

    Could you use fresh broccoli in this recipe or is frozen the better way to go?

  10. boosmom  December 30, 2012

    Using the points plus recipt calculator on the Weight Watchers website, this is actually 5 PointsPlus points per 1/2 a cup. Wouldn't be bad for a serving, but I think most people would eat at least 2-3 times for a meal.

  11. lynne p  December 30, 2012

    This is not so skinny…how many folks eat 4 oz of soup? The calories are on 1/2 cup size. Secondly, I have never needed to use flour to thicken my "cream" soups. A bit of pre-cooked mashed potato (no butter necessary) will thicken the soup. You can also use canned milk (not sweetened condensed!) or real cream, or regular milk.

  12. Dee  January 9, 2013

    Thanks. I think I will add some chicken to get some protein in there!!

  13. Becky Floyd  January 25, 2013

    I made this recipe and it was a disaster! The cheese became one huge ” blob ” although I tried to stir it in slowly as directed. I was very disappointed 🙁

  14. Marilyn  February 22, 2013

    I make a soup similar to this, but I use shredded Parmesan cheese for some of the cheddar. The stronger flavor of Parmesan lets me cut back on the amount cheese and still get lots of cheesy flavor.

  15. sheri  February 22, 2013

    Thank you for the wholesome recipe. All ingredients you can pronounce and no fake cheeses or canned milks or soups. The only thing I did different is use butter instead of olive oil. Yummm.

  16. Pat  August 7, 2013

    Do you have recipes for kidney patients?

  17. Angela  October 29, 2013

    Could you use Almond Flour in place of regular or Whole Wheat flour?

    • Skinny Ms.  October 30, 2013

      Angela, If almond flour helps to thicken it would work fine. I’ve never used it for this purpose so I’m not certain of its thickening qualities.

  18. Guest  November 6, 2013

    I made this soup to the letter and the cheese is sitting on the bottom of the crock pot. I used high quality block cheese!

  19. han  February 1, 2014

    Does this soup freeze well?

    • GaleCompton  February 8, 2014

      I've never frozen it and probably wouldn't recommend it.

    • Moblessed3  September 6, 2014

      Actually, I have made this soup and once cooled I put it in muffin tins. I then freeze the muffin tins. Once frozen, let thaw just a couple minutes till 'muffins' pop out with a butter knife. I then freeze the soup muffins in a freezer baggie and voila! You have 1/2 cup servings ready to go. It's the easiest way to have homemade soup at the ready…and I usually have two portions at a time because it's so delicious 🙂 Happy freezing!

  20. Kelly  January 8, 2015

    I made this tonight and just didn't think it was very good.

  21. Alison  January 24, 2015

    This looks wonderful! Can I sub the white or wheat flour with coconut flour? Thanks!! 🙂

    • SkinnyMs  January 24, 2015

      Alison, Yes you can use coconut flour instead of wheat.

  22. Katie  February 11, 2015

    Could I let it cook overnight and then reheat it?

    • SkinnyMs  February 12, 2015

      Katie, Yes you could do that, but add the cheese when you reheat it.

  23. Nicole  March 8, 2015

    This turned out really well!
    I made some modifications: added some sauted onions, chopped garlic, celery, leek, and corn, and some dehydrated mashed potato flakes to thicken it at the end. I also put less cheese.
    However I think the base recipe would have turned out really well without my changes!

  24. christine  March 21, 2015

    I freeze this all the time. I actually make double batches and measure out the 1 cup into containers. once cooled, throw them in the freezer. I defrost and nuke them all the time for lunches and it's quite delicious and filling for a lunch! My freezer is always stocked with this and I'm planning on making a double batch again this weekend.

  25. Lisa  March 18, 2016

    I may make this recipe but as I read through the comments, a couple of people have mentioned the serving size as half cup. The info at the top says 4 servings, 1 cup each, is this correct?

  26. Leigh  September 24, 2019

    Could I make this in an instant pot? If so, how would you recommend I do this? I’m thinking use the sauté feature on the IP until I add the frozen broccoli and then cook on manual high pressure for 15 minutes?

    • Nichole Furlong  September 25, 2019

      You got it, Leigh! Saute, add frozen broccoli, and high pressure for 15min should be perfect!
