Instant Pot Soup

Using an Instant Pot makes making soup so incredibly quick and easy. There's no need to watch the soup on the stove for a few hours to get that all-day simmering flavor that you get on a traditional stovetop. A pressure cooker can achieve the same great flavors in much less time which is a time saver for sure!

Cheese and heavy cream are added after the gluten free soup has been pressure cooked to create a cheesy and creamy cauliflower potato soup. Cream and cheese do not pressure cook well as these ingredients cause curdling under pressure.

What are the Ingredients in Cauliflower Potato Instant Pot Soup?

• Vegetables - cauliflower- 16 ounces of frozen or 1 head, carrots, garlic, onion, and potatoes
• Spices - Nutmeg, salt, and pepper
• Bacon - for garnish
• Chicken broth - low sodium
• Heavy cream - for a creamy texture
• Scallions - for garnish
• Cheddar Cheese - for a cheesy flavor
• Cornstarch and water- to create a slurry and to thicken the soup. Cornstarch is used in place of flour to make this a gluten free soup.

Quick and Easy Instant Pot Soup

Let's start by saying it only takes 3 minutes of pressure cooking time to make this Instant Pot Cauliflower Potato Soup with a 10-minute natural release.

To begin making this soup, the pressure cooker is set to sauté and the bacon is added to the inner liner. The bacon is then cooked and removed from the pot. The bacon grease remains in the pot.

The diced onion, carrots, and garlic are added and sautéed until the garlic becomes fragrant and the onions become translucent.

The broth is then added to the pot and the pot is deglazed before adding any other ingredients. It's worth a mention that this step is very important because if there any stuck-on bits, the Instant Pot will give a BURN notice.

Next, the small cubed potatoes are added to the pot as well as the cauliflower, nutmeg, salt, and pepper.

The lid is then closed as well as the vent and the Instant Pot is set to High Pressure for just 3 minutes. Once the 3 minutes is up, 10 minutes of natural release time is allowed before opening the pot.

The use of an immersion blender is helpful in this next step as it makes pureeing this soup easy. Puree half this soup right in the pot. If you don't have an immersion blender, a countertop blender can be used in its place. Remove half of the soup and carefully pour it into the blender. Allow the steam to escape while pureeing and once done, return the soup to the pot.

After this, the pressure cooker is set back to sauté and the shredded cheddar cheese and the heavy cream are added to the pot. To make this soup cheesier, at this point, a cornstarch slurry is added to make the soup thicker.

This soup is served with bacon pieces, additional shredded cheese, and scallions.
