INSTANT POT CAULIFLOWER SOUP

Cauliflower is a vegetable I make a lot in my house.

I will be honest it is one my kids don’t love yet, but they will eat a small bowl of this Instant Pot Cauliflower Soup. 

They like it topped with crispy bacon for that extra savory flavor. 

With this soup you can easily make it vegetarian by leaving off the bacon. It is low-carb and a great cold weather option to fill you up. 

Some of my favorite recipes are cauliflower recipes. I especially love this Turmeric Cauliflower and this Curry Roasted Cauliflower

I have also started using cauliflower rice in salads like this Mediterranean Chickpea Cauliflower Salad and this Cauliflower Tabbouleh

If you like cauliflower you have to try today’s Instant Pot Cauliflower Soup this winter. I love how easy this soup comes together in the Instant Pot too! 

Instant Pot Cauliflower Soup ingredients laid out.

WHAT INGREDIENTS ARE IN THIS CAULIFLOWER SOUP?

CAULIFLOWER: This soup uses about 1 1/2 pounds cauliflower (about half of a medium-sized head), cut into florets. 

ONION & GARLIC: Onion and garlic help to add flavor to this cauliflower soup. To add more flavor to this soup spices are also a nice addition. Sometimes I will add hot sauce, or paprika or Italian seasoning. 

I love using them but if you don’t have either on hand you can skip it or use garlic powder in place of the garlic. 

STOCK: The stock I use is vegetable or chicken broth. If you want to make your own chicken stock check this post out here and to make vegetable broth use this recipe. 

CREAM: The cream helps to create that silky, creamy texture of the soup. You can substitute milk in its place or try stirring in Greek yogurt to help create the creamy texture. 

 

CHEESE: The shredded white cheddar cheese is a nice pairing to this soup.

You can easily sub in something different like sharp cheddar, pepper jack for some spice or mozzarella cheese.

BACON: The bacon is optional and added after the soup is done. If you want a vegetarian soup just leave that out. You can use regular or turkey bacon as the topping! 

GREEN ONIONS: Green onion is a nice finishing touch to your soup. You can also add freshly chopped parsley, dill or chives.
