Ingredients for keto cauliflower soup

Now, for our recipe, we will be using mostly staple pantry ingredients and a few you might have to grab from the store. 

But the ingredients are all super easy to find, and are inexpensive too!

Here's what you'll need:

• 1 large cauliflower, cut into florets
• ½ tablespoon smoked paprika
• 2 tablespoon olive oil
• 4 thyme sprigs
• 1 onion, chopped
• 1 celery stick, chopped
• 1 garlic clove, minced
• 3 cups chicken stock
• ½ cups heavy cream
• Grated parmesan cheese for serving

Now, we'll not only be using the cauliflower to make the soup base, but to top the soup with it as well.

That said, if you would prefer to have more cauliflower throughout your soup, feel free to roast more and add extra florets in each bowl. 

And make sure you pick up some extra cauliflower so you can make these cauliflower steaks.

THE MAIN INGREDIENT: CAULIFLOWER 

Our main ingredient for this roasted cauliflower soup is, of course, cauliflower. 

And cauliflower is one of the most versatile keto vegetables out there. 

It can be used in a variety of different keto recipes, like mashed potatoes, pizza crust, and more.

Cauliflower also has one of the lowest carb contents out of all the vegetables and a high amount of fiber per serving.

Not to mention, cauliflower is packed with nutrients and has a low glycemic index. When it digests, it stabilizes blood sugar and does not spike insulin. That makes it one of the best vegetables to eat if you're following the keto diet.

Having said all of that, as far as the carb count goes on this soup, every cup of it has just 4g of NET CARBS!

How To Make Cauliflower Soup

Okay, so as I mentioned before, it will only take about 30 minutes to make this roasted cauliflower soup. 

All you have to do is roast the cauliflower, make the soup broth, and then blend everything together. It's easy-peasy!

Seriously, in just a few simple steps, you'll have an incredibly tasty soup. 

So gather your ingredients, and let's get into making this keto cauliflower soup.

STEP 1: Roasting the Cauliflower 

The first thing we will be doing to make this soup is roasting the cauliflower. Start by preheating the oven to 430°F (220°C).

Then cut the cauliflower into florets and cover them in 1 tablespoon of olive oil. Put the cauliflower florets on a pan and evenly sprinkle salt and smoked paprika over them. 

Next, put the cauliflower in the oven and roast for 15 minutes until the florets are golden. 

STEP 2: Sautéing The Vegetables

So, while the cauliflower is roasting you can start sautéing the vegetables for the broth.

And, to do this, you'll want to take out a large pot - or saucepan - and set it over medium heat.

Then, when that's all set, pour in a tablespoon of olive oil, and add in the chopped onion and celery. 

Cook for about 5 minutes until the vegetables are soft. After they are, add in the minced garlic and thyme, and cook for about 1 minute until fragrant. 

Step 3: Making the Soup 

So, after the cauliflower is roasted, you'll want to add the majority of it to the pot, but you'll also want to save some to top the soup with.

Then, when you've added the cauliflower to the pot, pour in the chicken stock and bring to a simmer— cooking for about 10 minutes.

Next, pour the soup from the pot into either a blender or food processor, and blend until a smooth consistency forms. 

Once smooth, add in the heavy cream and blend it in with the soup. 

To serve, top each bowl of soup with grated cheese, roasted cauliflower, and a drizzle of olive oil. 

How To Store This Keto Cauliflower Soup

This roasted cauliflower soup makes for an ideal leftover meal.

You can have it as dinner one night and then lunch a few nights later.

That said, you can store it in the refrigerator in an airtight container for up to 5 days. And to reheat the soup, just put it in a saucepan over medium heat until it reaches your desired temperature. 

You could also put it in the microwave in 30-second increments, and stir it every 30 seconds as well. 

FREEZING THE SOUP

By the way, if you want to keep this soup for longer, you can freeze it in either an airtight container or freezer-safe bags for up to 3 months.

Just make sure the soup has cooled completely before freezing. 

If you do freeze the soup though, I recommend defrosting the soup overnight in the refrigerator. That way, all you have to do is put the soup in a saucepan over medium heat, and heat it until it reaches your desired temperature. 

Having said all of that, whether you refrigerate or freeze your soup, it will be quite thick after it sets overnight.

So, when you reheat it, just add water or broth a tablespoon at a time to thin it out.
