Ingredients

Fresh or frozen cauliflower florets or a whole head of cauliflower can be used to make this soup in the pressure cooker. I find they both work equally well.

Anchovies are used to add a deep, umami flavor to the soup. If you think you don't like anchovies, just try it - they are incredible used in this recipe - you won't even know they are there.

A good chicken stock or this homemade instant pot chicken bone broth is important to ensure flavor and richness,

True to many of my other recipes, bacon is also a key flavoring ingredient. It adds a nice smoky flavor and some texture to the soup.

A full list of the ingredients is included in the recipe card at the bottom of the post.

Topping ideas and/or recipe variations

Substitute shredded cheddar or any other shredded cheese for the Parmesan cheese - or just sprinkle cheddar cheese on top.
Crumbled bacon. You can also mix in some browned sausage or pieces of cooked pancetta.
Sour cream or creme fraiche. Stir in additional heavy cream for a creamier soup.
Chives, diced green onions or crispy fried onions.
Fried garlic chips.
Sprinkle with chili powder or cayenne pepper for some extra spice.
Drizzle with Argentinian chimichurri sauce or this red chimichurri sauce.
Croutons or buttery toasted bread crumbs.
Replace the chicken stock with vegetable stock and cream with coconut milk (and omit the anchovies) to make it vegan.
Use roasted cauliflower to give the soup a slightly smoky, sweet flavor.

Expert tips to make cauliflower soup in the instant pot

If you don't have an immersion blender, you can use a regular blender. Remove the soup from the heat and let it cool for a few minutes. Blend in batches and place back in the Instant Pot.
If the soup is too thin, mix 1 tablespoon of cornstarch with 1 tablespoon of water and slowly pour the mixture into the soup while stirring. It should thicken after a few seconds. Add more if necessary.

Frequently asked questions

Why is my cauliflower soup tasteless?

Typically, a bland cauliflower soup is due to lack of seasoning. If using an unsalted stock to make this, you will need to add additional salt to bring out the flavor of he soup. You can also simmer it with the lid off for 10-15 minutes to concentrate the flavor more.

How do you thicken cauliflower soup?

To thicken cauliflower soup, simmer it with the lid off for 10-15 minutes. You can also mix in a cornstarch slurry (1 tablespoon water mixed with 1 tablespoon cornstarch) while the soup is simmering to help thicken it.

Why does my cauliflower soup taste bitter?

Cauliflower can start to taste bitter if it is overcooked. To counteract the bitterness, add additional salt or a pinch of sugar to the soup. You can also add a little bit of lemon juice or vinegar (before mixing in the cream) to counteract the bitterness of the cauliflower.
