Crockpot broccoli cheese soup is quick to throw together and makes 12 cups of soup – plenty enough to serve your family dinner and still have leftovers for lunch. Just 4 net carbs per bowl! This soup is perfect for chilly nights.
Broccoli is officially my favorite vegetable, which is weird because I feel like broccoli really gets a bad rap.
I mean, it’s so green and funky looking. Kids love to hate it. It kinda stinks when you steam it.
But, y’all, it’s just so GOOD and so easy to doctor up! I can do a million things with broccoli.
I kind of wonder if the broccoli haters out there are mostly only hating it because they are starting with frozen broccoli rather than fresh.
When I finally discovered my love of broccoli, I quickly grew tired of chopping up heads of broccoli every other day, and I ran to Costco and bought a jumbo sized bag of frozen broccoli florets. I thought I was soooo smart.
Then I steamed that frozen broccoli and served it to my family and basically no one ever spoke to me again. They still hold a grudge.
Moral of the story: if you think you don’t like broccoli, be sure to try fresh broccoli instead of frozen. They’re different. 🙂
Anyway, let’s talk about this crockpot broccoli cheddar soup! It’s basically comfort food in a bowl, but it’s also healthy (hello, vegetables), low carb, and will feed a crowd. Love this recipe!!
How to make crockpot broccoli cheddar soup:
Slow cooker broccoli cheese soup starts with a whole lotta broccoli.
I use fresh, as mentioned above. I generally just buy the bags of already chopped broccoli florets because I’m lazy, but you can definitely start with a couple heads of broccoli and chop it up yourself.
Toss the broccoli into a slow cooker. I use the Ninja and love it. (affiliate link)
To your broccoli, add in some onion, garlic, chicken broth, cream, mustard powder, salt, pepper, and red pepper flakes. We want flavor in this soup and we’re going to get it! 🙂
Cover and cook on low for about 4 hours or until your broccoli is very tender.
The color gets a little funky after all that cooking, but just trust me. Things are going to get prettier and super delicious in a minute.
Here comes the fun part: blending it up.
I use an immersion blender and just pop it right in the slow cooker to do it’s thing. Here’s the one I have and love. (affiliate link) I think it’s a worthwhile investment – it’s fairly cheap and, while I don’t use it every day (or even every week), it’s super handy to have when you need it and doesn’t take up much space.
If you don’t have an immersion blender, you can carefully transfer the hot soup to a traditional blender and blend it in batches. Be sure to vent the steam as you blend and just be careful not to burn yourself.
Back to the slow cooker for the good stuff…
Cheese! Lots of cheese! You can’t make broccoli cheddar soup without cheddar, but I also add in Monterrey jack for extra creamy goodness.
Stir that around until the cheese is melted and you’re done! Creamy broccoli cheddar soup!
So easy, right?
Top it off with extra cheese and some crispy bacon, if you like.

Followed the recipe exactly except I added a couple of chopped carrots because I had some laying around, and the result was delicious! It was not too thin or runny; it was actually quite thick. The broccoli taste was not strong. Thanks for the recipe; I’ll be making this again!
Karly Campbell says
Thanks for sharing, Angie!
Ashley Stibolt says
This says 1g for a serving size. Did this mean 1 cup not gram?
Karly Campbell says
Oh sorry about that. Our recipe card just started adding that in when we don’t specify. It should be right around 3/4 of a cup. 🙂
Susan Gapinski says
How long can you keep in refrigerator after its made?
Karly Campbell says
This should last for 4-5 days.
Dana says
Excellent. Freezing cold Super Bowl Sunday here in Michigan. Family loved it!
Karly Campbell says
Glad it was a hit, Dana!
Jeanne says
What a wonderful chilly night dinner recipe. I love broccoli and cheese but have never made this soup. Could not have been easier. I worked downstairs while the crock pot was working away upstairs. Nice flavors and texture. Served it with a small salad and crusty bread and voila! — a filling and comforting meal.
Karly Campbell says
Thanks, Jeanne!
Meghan says
I thought the recipe turned out great! And it super easy to throw together. My only issue was that when I put all of the ingredients into my nutrition calculator, it was 9g of carbs per serving not 4g. Just curious how are numbers are so off …
Karly Campbell says
Hi Meghan! It’ll depend on specific products being calculated as well as the types of measurements used and where the info came from. Our info is pulled from the USDA and usually accurate, but it is calculated automatically so we don’t guarantee it. 🙂
Liisa Bartges says
This is a go to recipe in our house. Turns out perfectly every single time.
Karly Campbell says
Thanks Liisa!
Brian says
4 cups would equal how many grams of cheese. I googled it and I get different answers.
Karly Campbell says
Generally 4 ounces of shredded cheese equals 1 cup. I have no idea how that converts to grams.
Brian says
Thank you
Steve says
Turned out runny. What to do? Followed recipe. Too spicy too.
Karly Campbell says
Hi Steve! You can add more cheese to try to thicken it up if you like. Not sure why it would be spicy though – 1/4 teaspoon of red pepper flakes against that whole crockpot full of soup shouldn’t have much impact at all.
Kim says
Mine turned out too thin too.
irma says
If you use frozen broccoli, can you throw it in frozen or must defrost first?
Karly Campbell says
I haven’t made this with frozen broccoli, but I think you’d be fine to toss it in frozen. It may take longer in the crockpot though.
Deborah Pinker says
I always put in cream of cheddar, celery or any cream soup.
Layne says
It would probably be a benefit to put the whole cheese issue in the actual recipe and not just the comments 🙁
Karly Campbell says
Hi Layne, I’m not sure what ‘cheese issue’ you’re referring to? The recipe is written as I make it and has loads of good reviews.
Beth Cooper says
It is in the receipe-4 cups chicken broth
2 cups heavy cream
1 teaspoon ground mustard
1 teaspoon salt
1 teaspoon pepper
¼ teaspoon red pepper flakes
4 cups grated cheddar
1 1/2 cups grated monterey jack
Instructions
Add the broccoli, onion, garlic, chicken, broth, cream, ground mustard, salt, pepper, and red pepper flakes to a 6 quart slow cooker.

Add the cheese to the hot soup and stir well until melted and creamy.
Serve immediately with additional grated cheese and crumbled bacon, if desired
Susan says
I haven’t tried it yet, but I’m wondering if you have a conversion to use an instant pot instead of a crock pot?
Karly Campbell says
I’d probably add everything up to the chicken broth for 4 minutes, quick release and then stir in the rest of the ingredients. I haven’t tested it, but that’s where I’d start. 🙂
Wendy R says
Back in the bad old days, I would make a crock pot potato soup and would add cream cheese the last hour. How do you think that would affect this recipe?
Karly Campbell says
I think it would work fine, but I haven’t tried it. Should be good though. 🙂
