How to make a weeknight soup?

A family favorite, this recipe for Broccoli and Cheddar Soup is simple enough to be whipped up on a weeknight in just about 30 minutes. No need to simmer and stir all day and you may already have the ingredients on hand!

With whole foods and clean keto ingredients this is a thick, creamy, hearty soup that the whole family will enjoy. Here is the list of ingredients to grab from the grocery store or pantry and get started on an amazing weeknight soup:

  • Butter
  • Sweet Onion
  • Garlic
  • Xanthan Gum (keto/GF thickener for sauces, creams, soups and gravy)
  • Broccoli florets
  • Cheddar cheese-block or shredded
  • Heavy Whipping Cream
  • Chicken Stock or Broth
  • Salt and Pepper
  • Smoked Paprika

The importance of clean, one ingredient foods.

My success on keto I attribute to eating clean. Choosing wholesome, one ingredient foods that either come from the ground or come from an animal that eats from the ground. Seriously though, it’s true! The cleaner I eat, the better I feel and if we talk about weight loss……..the more weight I lose.

Now don’t get me wrong, I do have keto ‘snacks’ here and there, I am human! But, for the most part, I try to steer away from packaged items and stick with whole foods.

In the beginning of my keto journey, I just ate ‘keto’ to learn keto and get what is called ‘keto adapted’ or in ‘ketosis’. So whether it was a keto snack, a fast food burger or keto ice cream, I ate it if it fit into my daily carb count. Plain and simple, I needed to get some weight and inflammation off. As I have went deeper in my keto lifestyle…(19 months and 95 pounds later, to be exact), I am looking to get those last 15 pounds off but really looking at my overall health, the way I feel and what I put into my body.

Now, let’s get back to our Hearty Keto Broccoli and Cheddar Soup!

The ingredients in this soup are clean and wholesome and delicious, foods I choose to eat everyday on my keto journey.

Tips for making Hearty Keto Broccoli and Cheddar Soup

Finally, as you make this wonderful, warm, thick hearty keto soup, I have a few tips to bring it all together.

  • When adding the Xanthan Gum to the butter, onion and garlic step of the recipe. Stir the Xanthan gum completely and for several minutes, this will start the thickening process.
  • Use frozen broccoli florets!!! Make it simple, it’s a weeknight soup!
  • I recommend buying the cheese in a block and shredding it yourself. It really takes no time and has no added starches or coatings to keep it from sticking together like you find in pre-shredded cheeses.
  • I use a potato masher once I have added in the broccoli florets or at the very end of making the soup to chop up some of those bigger broccoli pieces. I do love a chunkier soup, but mash to your liking.
  • Do not substitute half and half or milk for the heavy whipping cream. This is a keto soup!
  • This is a thick hearty soup, if you want yours a bit thinner, just add a little more chicken stock.
  • For the cheese, I used a Medium cheddar cheese, but use whatever cheddar you like or mix two types of cheddar like sharp cheddar and smoked cheddar.
  • Make a double batch, this freezes well!

This soup could be a complete meal on it’s own, but would be well paired with a chaffle sandwich or simple lettuce salad. Now, if you love this soup, I also think you will love my Keto Roasted Tomato Soup!
