Instant Pot Loaded Roasted Cauliflower Soup

Ok friends this is a delicious soup.

You’ve got to try it!

I’ve been wanting to make this type of recipe in the Instant Pot for a long time.

What was holding me back you ask?

Well have you seen the ridiculous price of cauliflower lately??

I just could not justify it.

But finally last week a sale….

And I bought the most beautiful, big cauliflower. EVER.

When you’re adulting and trying to survive in this crazy economy, it’s the strangest things that get us most excited dont you find? LOL

Well, anyways, I knew immediately what I was going to make with it.

A Loaded Cauliflower Soup of course!!

The recipes I found on the web were apparently inspired by keto followers that wanted to capture all the deliciousness of a Loaded Potato Soup, but in a low carb version, which of course means no potatoes.

Although I personally don’t follow such a diet, I thought the idea of using cauliflower instead of potato was genius.

So I found some basic recipes for the loaded soup and adapted them to create my own version.

The big change I made was to roast the cauliflower, onion and garlic. I was going for maximum flavour.

It does add a bit of time to the total cooking process, but I find it is always, and I mean always, worthwhile to roast the veggies for use in soups.

Roasting brings out an extra layer of flavour that’s not to be missed.

Trust me on this.

Use an immersion blender to puree the soup right in the Instant Pot, it’s so easy.

I highly reccomend this method, instead of pouring your soup into a blender.

Now, what makes this soup even more delicious is of course the toppings.

The idea here is to use the same toppings you might use to load up your baked potato.

Bacon, cheese, chives….you could even stir in some butter or add a dollop of sour cream.

The end result is going to be delicious.

An excellent soup for a cold winter day.

There’s another storm in the forecast for tomorrow, please stay warm, stay safe and you might as well make soup!
