How To Make Low Carb Broccoli And Cheddar Soup
When you taste this broccoli cheese soup recipe, you won’t believe it came together in less than 30 minutes!
It seriously tastes like it was made in a diner and slow-cooked all day, can you believe that? My stomach is growling, just thinking about it.
Low Carb Broccoli Cheddar Soup Ingredients
You will need the following to whip up a batch of this broccoli soup:
Butter
White onion
Garlic, minced
Chicken broth
Broccoli, coarsely chopped
Salt and pepper, to taste
Heavy cream
Cheddar cheese
Xanthan gum
You can easily use frozen or fresh broccoli, depending on what you have on hand. Follow the same directions, but know that frozen broccoli may take a little bit longer to soften.
Plus, I love cheddar cheese, but you could try different varieties like mozzarella, Colby Jack, or even Pepperjack to kick it up a notch.
Don’t you love how versatile it is?
Another option is that you can use vegetable broth instead of chicken if you’d rather.
(Just keep in mind when making swaps, sometimes the texture will vary, and of course, the flavor will be a little different.)
How To Make Easy Broccoli Cheese Soup
(For a full printable recipe, scroll down to the bottom of the post)
Start off by using a medium stockpot and melt the butter over medium-high heat. Toss in the diced onions and minced garlic and cook until they have softened around 3 minutes.
Next, mix in the chicken broth and broccoli and allow it to boil then reduce heat to medium. Let the broccoli simmer until it has softened and can be pierced with a fork easily.
Sprinkle some salt and pepper on to taste.
Pour in the heavy cream and turn the heat back up to medium-high and let the soup boil.
After it begins boiling, remove the pot from the stove and stir in the cheddar cheese. Make sure to scrape the bottom of the pan, so it doesn’t stick.
NOTE: The cheese may stick to the broccoli, and that’s normal.
Add the xanthan gum to the top of the soup then give it a stir. Let the soup rest, and it will thicken as it cools down.
Add your favorite toppings like crumbled bacon, cheese, black pepper, or sliced green onions and serve hot. Enjoy!
How Do You Store Broccoli And Cheddar Soup?
Whether you ended up with leftovers intentionally or not, this cheddar cheese soup is a wonderful leftover!
Let the soup cool all the way (make sure not to let it sit out for longer than 2 hours) after it’s cooled, put it in an airtight container and keep it in the fridge for 3-4 days or in the freezer for 6 months.
I love this broccoli soup recipe because it can be made ahead of time for meal prepping and planning! It will save you tons of time to have an easy meal just ready to warm up.
How Do You Reheat Low Carb Broccoli Soup?
It’s so easy to reheat this low carb soup. If you have frozen it, you need to let it thaw out in the fridge overnight or until it’s defrosted all the way.
After the soup is thawed, simply place it in a stockpot and begin reheating it on medium heat.
Don’t warm it too fast, or the cheese may separate a little, and it will have a strange texture.
Another option is to place the soup in a microwave-safe bowl and cover it with a paper towel. Heat the soup for 1-2 minutes and give it a stir. It warms up pretty quickly, so keep an eye on it.

Make sure to reduce heat to a simmer before adding cheese. It is too hot if you add it after boiling even after you take it off heat. This causes the cheese to sieze.
Donna
This was delicious on a cold and rainy day in Southern California!
Sarah Hardy
So glad you enjoyed it!
Lisa Smith
Can you use frozen broccoli?
Sarah Hardy
I think so, but I haven't personally tried it with frozen broccoli.
Pam
What if I don’t have Xanthan gum?
Sarah Hardy
You can also cook it just a bit longer to reduce it (just keep it on a low temperature), or you can also use a sprinkle of glucomannan instead of the xanthan.
Angel
This looks delightful! Would this be a complete thm S meal or would you need to add something? Thanks!
Sarah Hardy
I would probably just eat it as is. You could add a low-carb roll (I have a FP Roll recipe), or a side salad.
