Keto Broccoli Cheese Soup

Recipe Highlights

  • How does it taste: Keto broccoli cheese soup taste exactly like broccoli cheese soup. The key is in the preparation and the cooking for a creamy, cheesy broth for serving. Carrots are low carb in lower numbers. You can enjoy there slightly sweet flavor alongside hints of garlic, onion and of course the cheesy base.
  • Skill level: A easy recipe to prepare but with strict instruction for the best result. There is very little broth used for a reason and the end result is a creamy broth that is free of flour and cornstarch. Perfect for a beginner and a good way to learn how things are manipulated on the keto diet to make recipes work and turn out great.
  • Storing: Keto broccoli cheese soup refrigerates well but does not freeze well at all. Freezing will cause the base to separate when thawed but stirring may or may not bring it back together. It’s hard to say due to many factors. A tiny bit of xanthan gum can be used and they’ll help stabilize the sauce more for freezing but only if you have experience using it. A little of xanthan gum goes a long way and it’s tricky, which is why I avoid adding it into the ingredients list when possible.

Ingredient tips

  • Broccoli: Fresh broccoli florets are used in the recipe but frozen won’t be an issue at all if it’s what you have on hand.
  • Carrots: Adding carrots are not going to mess up the net carb count in the volume that I use. The keto broccoli cheese soup will still be delicious without them if you’re new to keto and a bit anxious. Shredded carrots are highly recommend for the net carb reason and to avoid huge chunks of carrots in the soup.
  • Cheese: Only freshly grated cheddar cheese for the recipe. The melting of the cheese is the key to the entire base of the broth to become cheesy. There is no flour or cornstarch so the only thing to thicken the soup are the cheeses and the thickness of the heavy cream. If the cheese has a non-caking agent on it (as pre-shredded cheese does) the recipe will not turn out correct as you see in photos.
  • Cream cheese: Do not skip this ingredient because the cream cheese acts similar to tomato paste for the broth for thickening.
  • Chicken broth: There is little broth in the recipe due to the veggies that will produce more liquid and to manage the thickening of the soup. This is taken into the consideration of calories as well. If calories aren’t your concern and only the carbs you can double the liquid, heavy cream and the cheese in the recipe to have more broth in the end. Note, the more liquid such as broth or water the thinner the end broth will be.

Storing tips

As mentioned, the keto broccoli cheese soup will not freeze well. For more stabilization of the soup, xanthan gum can be used. Less than 1/8 teaspoon is enough which is slightly more than a pinch. Quickly whisking (a whisk is important and not a spoon) will help prevent lumping and a correct distribution of the gum.

Variations

Crockpot Instructions:

With a crockpot on high heat add all ingredients except the cheddar cheese. Cook down and reduce about an hour until broccoli is tender. Add in cheddar cheese and cook about 15 minutes then serve. Taste and season with salt and white pepper.

Instant Pot Instructions:

On sauté setting, add in butter, diced onion and garlic. Once fragrant pour in chicken broth, heavy cream, cream cheese, broccoli and carrots. Place on high pressure, close lid and cook for 7-10 minutes. Open and add cheddar cheese mix around until melted then taste and season with salt and white pepper until flavor is perfect.

Ingredients
 

  • 2.5 cup chopped broccoli
  • 3 ounce shredded carrots
  • 1/2 diced onion
  • 3 clove chopped garlic (sub for 1 TB minced garlic)
  • 2 tablespoon butter
  • 1 cup chicken broth
  • 1/2 cup heavy cream
  • 4 ounce full fat cream cheese
  • 1 cup shredded sharp cheddar cheese (112g weighed out)

Instructions
 

  • Dice onion and chop up broccoli as fine as you'd like. I chopped roughly in this recipe
  • In a large pot on medium high heat add butter and diced onion. Once fragrant add in chopped garlic. Note, in the video I used chopped garlic. I now feel grating the garlic over the soup before covering with a lid is the best method.
  • Pour in chicken broth, lower the heat and bring to a simmer. Add in cream cheese and heavy cream.
  • Add in chopped broccoli and carrots and bring to a simmer then cover. Check in every few minutes to make sure it's a slow simmer and to check the tenderness of broccoli.
  • Once broccoli is tender toss in shredded cheese and mix in until all melted. Season with salt and white pepper. Taste for seasoning then serve while hot.

10 thoughts on “Keto Broccoli Cheese Soup”

  1. I’m making now, and it seems one cup of broth and 1/2 cup cream isn’t even near enough liquid with that much broccoli!

  2. I know it doesn’t seem like a lot. Due to not using flour the less liquid allows the broth to thicken up properly when the cheese is added. That’s why I say cover so the broccoli can steam and release water to aid with cooking before everything is done.

  3. 5 stars
    5-5-2024 – I made this recipe and the only thing I did that was different was I added 2 cups of chicken stock. This was actually a mistake on my part, however it turned out very good. This is definitely a recipe I will be keeping and making again.

    Many people think there isn’t enough broth in the soup but without flour this is the trick to the cheesy, creamy texture that broccoli soup is known for. Yes, less broth but the perfect texture.

  5. I do not recommend you freezing it due to the dairy. The dairy components will separate after thawing without stabilizers added to the soup.
