Servings: 4 people
Author: Guest Post
  • 3 Large Leeks White parts only, sliced
  • 1 Medium Cauliflower Cut into small chunks
  • 4 Garlic Cloves Peeled
  • 3 Cups Chicken Broth Divided
  • 1 Tsp Ground Cinnamon
  • 4 Oz Ricotta Cheese

  1. Add the leeks, cauliflower, garlic, chicken broth, and cinnamon to the Instant Pot. Season with salt and black pepper to taste. 

  2. Add the Instant Pot lid and lock into place. Switch the vent to “Sealing” position and set the “Manual” setting on high before adjusting the cook time to 9 minutes. After a brief pause, the Instant Pot will automatically start to build pressure.

  3. When that is finished cooking, do a quick release (QR) to allow the pressure to escape. Unlock and carefully remove lid. Add the 12 ounces of cheese (sharp cheddar, ricotta, and cream cheese) and mix until the cheese has fully melted.

  4. Blend with an immersion blender until the cauliflower leek soup is smooth. 

  5. Serve hot or chilled with optional toppings.

Instant Pot Soup Questions

First time using your Instant Pot to make soup? No problem! Here’s a few common FAQs to help you get started on the right foot when using your Instant Pot.

When do you use the Instant Pot soup button?

You should use the Instant Pot soup button whenever you’re looking to make broth, stock, or soup.

How long is the Instant Pot soup setting?

Luckily, Instant Pot soup doesn’t take long at all! The soup setting will take anywhere from 20 to 40 minutes, depending on your selection. It starts at 30 minutes and can be adjusted down to 20, or up to 40.

How does the Instant Pot soup setting work?

One of the reasons the Instant Pot is so great is because the buttons do different things. When it comes to soup, the Instant Pot heats up slowly and gradually. If you were to select Steam, it would heat up faster as there should be no food in contact with the bottom of the Instant Pot. So, once you use the Soup function, your soup, broth, or stock will heat up gradually. This is especially useful for soups that tend to boil and spill over.
