Instant Pot Cauliflower Soup Ingredients:
I made this loaded cauliflower soup using fresh cauliflower. To add flavor to the broth I sauteed onion, garlic, and celery in bacon grease. The broth is so aromatic and flavorful. To get the right creaminess I used a combination of heavy cream, sour cream, and sharp cheddar cheese.

Benefits of Cauliflower:
Cauliflower is one of the most versatile vegetables. It can be roasted, grilled, boiled, fried, steamed, eaten raw or pickled. It's also a great ingredient for making a healthy cauliflower pizza crust.
Cauliflower has a similar nutrition profile to broccoli and only has 2 grams of net carbs per cup (shredded). For this reason, cauliflower is a great addition to your low carb or keto diet. It's the perfect substitution for potatoes, rice, and other higher-carb foods.

How to Add Creaminess and Flavor to Cauliflower Soup:
Due to its mild taste, cauliflower soup may need extra seasoning. To avoid bland cauliflower soup, I added some sharp cheddar cheese, heavy cream and sour cream to the soup. My father-in-law said it tastes like his three-cheese soup, just a much healthier version of it.
Fortunately, cheddar cheese is low in carbs and high in fat, which makes it a great fit for a ketogenic diet.
I highly recommend using freshly grated cheddar cheese over pre-shredded because freshly grated cheese doesn't contain added preservatives and chemicals. As a result, the soup will have a fresher and creamier taste.

Pressure Cooker the Cauliflower Soup:
- Add cauliflower florets, broth, salt, and pepper to the pot. Turn off the instant pot, place the lid and seal.
- Select “soup” and adjust the timing to “5 minutes”. Once it’s done, let it on natural release for 10 minutes before opening the lid.
Puree the Cauliflower Soup:
- Open the lid, use a hand blender, puree the cauliflower. Please do this carefully.
- Pour in the heavy cream, sour cream, and cheddar cheese. Keep stirring until the soup is smooth and creamy. Adjust seasoning with salt, pepper, and extra cheese if needed.
- Turn off the instant pot. Serve with crisp bacon and enjoy!
