Since I’ve had to adjust my diet this year, I’m making a lot more low-carb recipes.

I hadn’t really planned on creating low-carb or keto recipes, but it seems like my body had something different in mind.

Since I’ve changed up my diet I feel so much better! All of my inflammation has disappeared and I have so much energy.

This keto broccoli cheese soup was one of the first keto recipes that I made and I’ve been keeping it on repeat. It’s so good, it freezes well, and It’s delicious for a quick and easy lunch or a dinner paired with a fat salad!

What You’ll Need

  • Broccoli. This recipe calls for 4 cups of broccoli florets. I usually buy 2 or 3 broccoli crowns depending on how large they are.
  • Celery. 2 stalks of celery diced.
  • Onions. White or sweet yellow onions are fine for this recipe..
  • Broth. Chicken broth or vegetable broth both work for this recipe.
  • Cheddar. I like using a mixture of sharp cheddar and white cheddar. White cheddar is a little bit milder in flavor. A box grater makes quick work of shredding.
  • Heavy cream. Use heavy cream because heavy cream has the least amount o milk sugar and therefore is the lowest carb dairy. You can also sub in coconut milk or almond milk.
  • Thickener. Xanthan gum is essential in your keto kitchen. It’s used to thicken and emulsify. It’s a low carb stand-in for gluten.
  • Spices. The spices in broccoli and cheddar soup are simple. Nutmeg, salt, pepper, and bay leaves.
ingredients for broccoli cheese soup


Step 1 Start by sauteing your veggies in the butter.

Sauté the celery and onions in butter until they are fragrant. 3 to 5 minutes. Then add in the broccoli stems. Let them cook for another 5 minutes.

Step 2 Add in the broccoli and the chicken stock.

Add the chicken broth and the broccoli florets to the dutch oven. Cook until the broccoli is tender.

Step 3 Puree, if desired.

Use a stick blender to puree the soup until it is smooth and creamy. If you don’t have a stick blender you can also use a blender.

Step 4 Add in the heavy cream and the cheddar cheese.

The heavy cream and the cheddar cheese will melt into the soup. To thicken the soup, mix the oil and the xanthan gum together then add it to the soup. Bring the soup to a boil and allow it to thicken.
