The weather starts to chill, so it’s time to warm our souls with a delicious keto soup. I am always excited about comforting recipes because I love cold weather and delicious pumpkin recipes.

I am going to fill My Keto Plate blog with tons of my favorite soul-warming recipes, keto-fied. Keto Broccoli Cheddar Soup is one of those recipes that I can’t stop making because everyone in my family absolutely loves it

Let’s start with one of my most favorite of them all, super simple recipes that need only a few low carb ingredients.


Imagine that this soup has heavy whipping cream, cheddar cheese and you’ll serve it with crispy bacon bits and more cheese on top.

The secret is to use high-quality ingredients. Shred your cheddar cheese and don’t use the cheapest brand you can find. It lacks flavor.

  • 1/2 cup medium onion diced
  • 2 garlic cloves minced
  • 5 cups chicken broth
  • broccoli 
  • cheddar cheese 
  • 1 cup heavy whipping cream
  • 1 tsp xanthan gum optional (for a thick keto soup)
  • 1 tsp salt
  • 1 tsp pepper
  • 1 tsp smoked paprika
  • 4 slices bacon fried and crumbled

I’m a firm believer that while eating high fat low carb is good for you it but will never taste the same as the high carb versions.

The serving size of the soup that in my opinion is more than enough if it seems little it’s one cup that comes with 33 grams of fat.

How to make keto broccoli cheddar soup?

  1. Start by sauteeing the onion and garlic in butter to allow the flavors to develop. Fry for a few minutes until the onion is translucent and smells delicious.
  2. Sautee the broccoli and then simmer the soup until the broccoli is fork-tender.
  3. Pour the heavy cream and stir in the cheddar cheese. It’s important to use high-quality cheddar cheese because it’s crucial for flavor and texture.
  4. When ready to serve garnish with some crispy bacon bits and shredded cheddar cheese.

The taste is fantastic but if you want a thick soup to use something like xanthan gum, psyllium husk powder, guar gum or coconut flour to improve the texture.

Hi there. As a vegetarian I am looking for keto soups. I thought this was vegetarian but you list chicken stock and also bacon as part of the ingredients. This is misleading and I’m disappointed I can’t use this recipe.

Joanna March 4, 2019 - 10:22 am

You can skip the bacon and add smoked paprika!

Natalia blakely May 13, 2019 - 11:00 pm
