When I created this recipe with my niece Kara, we absolutely could not wait to share it with you!

And it’s just in time for serious soup weather, are you ready for that?

We made the soup in my  6 Quart Instant Pot (affiliate link) and our only regret was that we hadn’t made a bigger batch. If you have an 8 Quart Instant Pot (affiliate link) you could double the recipe for Instant Pot Loaded Cauliflower Soup if you’d like. For those who haven’t caught the Instant Pot fever just yet, I’m going to give stovetop direction as well, because this soup would be super simple to make on the stove.

How to Make Instant Pot Low-Carb Loaded Cauliflower Soup:

1. Chop up the onion and the cauliflower.
2. Melt butter or heat oil in the instant pot on the SAUTE setting and cook onions for 2-3 minutes.
3. Then add the chopped cauliflower, chicken stock, garlic powder, and salt.
4. Lock the lid, use the MANUAL setting and cook on HIGH PRESSURE for 5 minutes. Quick release the pressure.
5. While the soup cooks, prepare the cream cheese cubes, grated sharp cheddar, and cream (or use milk or half and half), as well as the additional cheese, sour cream, crumbled bacon, and sliced green onions for toppings.
6. Turn the Instant Pot to KEEP WARM setting and use an immersion blender (affiliate link) to puree the soup to your desired consistency.
7. Check to see if you want to add a little more chicken stock to thin the soup (or reduce the liquid on the SAUTE setting if it’s too thin).
8. Add the cheese and cream cheese, let it melt, and stir to combine.
9. Then stir in the half and half, heat through, and season to taste with salt and fresh-ground black pepper. (Taste before you add more salt.)
10. Serve Instant Pot Low-Carb Loaded Cauliflower Soup hot with grated cheese, sour cream, crumbled bacon, and sliced green onions to add at the table as desired.

This soup is guaranteed to be a hit, and many readers have reported that family members who “don’t like cauliflower” have gobbled it up.

Instant Pot (or Stovetop) Low-Carb Loaded Cauliflower Soup 

Yield 6 servings

Prep Time 25 minutes

Cook Time 5 minutes

Total Time 30 minutes

Instant Pot Low-Carb Loaded Cauliflower Soup is a soup recipe you'll make over and over, and this tasty soup is even a hit with people who say they don't like cauliflower!

Ingredients

• 1/2 onion, chopped small
• 2 T butter or olive oil
• 1 large head of cauliflower, trimmed and coarsely chopped.
• 3 cups chicken stock, plus a little more to thin soup if needed
• 1 tsp. garlic powder
• 1 tsp. kosher salt
• 4 oz. cream cheese, cut into cubes
• 1 cup grated extra sharp cheddar cheese
• 1/2 cup half and half (or use heavy cream or milk if you prefer)

Topping Ingredients:

• extra grated sharp cheddar or extra sharp cheddar cheese (optional)
• sour cream (optional)
• 8-10 strips bacon, cooked crisp and crumbled (optional)
• thinly sliced green onions (optional)

Instructions

1. Peel onion and chop into small pieces.
2. Cut away the leaves of the cauliflower and some of the stem, keeping the core part. Coarsely chop cauliflower into pieces.
3. Turn Instant Pot or pressure cooker to SAUTE and melt the butter; then add the onion and cook 2-3 minutes.
4. Then add the chopped cauliflower, chicken stock, garlic powder, and salt.
5. Lock the lid, use the MANUAL setting and cook on HIGH PRESSURE for 5 minutes.
6. Quick release the pressure.
7. While the soup cooks, prepare the cream cheese cubes, grated sharp cheddar, and half and half. Also cook and crumble the bacon, dish up sour some sour cream and extra grated cheese, and slice the green onions for toppings.
8. Check to make sure the cauliflower is very tender; then turn the Instant Pot to KEEP WARM (use simmer or low for other pressure cookers.)
9. Use an immersion blender (affiliate link) blender, or food processor to puree the soup. (I highly recommend using an immersion blender to puree the soup in the pressure cooker if you have one. Be very careful with the hot liquid if you remove it to a blender or food processor to puree.)
10. Check the thickness of the soup and add more stock if you want it thinner or simmer a little to reduce if it seems too thin.
11. Add the grated cheese and cream cheese cubes and let them melt, then stir to combine.
12. Add the half and half (or heavy cream or milk) heat through, and season with salt and fresh-ground black pepper. (Taste before you add more salt.)
13. Serve hot, with grated cheese, sour cream, crumbled bacon, and green onion to add at the table

Stovetop Directions:

1. Prepare ingredients as described above, but use 3 1/2 cups chicken stock for stovetop version. Use a heavy dutch-oven type pan that will hold all the ingredients.
2. Heat butter or oil in the dutch oven, add the onion, cook 2-3 minutes.
3. Then add the chopped cauliflower, chicken stock, garlic powder, and salt.
4. Bring to a boil, then turn heat to medium-low and simmer until the cauliflower is very soft, probably 20-30 minutes.
5. Puree soup as above, and check the amount of liquid. If it's too thick add a little more stock and if it seems thin, cook a few minutes more to evaporate some of the liquid.
6. Turn heat to low, add the grated cheese and cream cheese cubes and let them melt, then stir to combine.
7. Add the half and half (or heavy cream or milk) and heat through, and season with salt and fresh-ground black pepper. (Taste before you add more salt.)
8. Serve hot, with grated cheese, sour cream, crumbled bacon, and green onion to add at the table as desired.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Instant Pot Loaded Cauliflower Soup is great for low-carb or low-glycemic diets. However if you’re strictly following the South Beach Diet you’ll want to use lower-fat dairy products, use olive oil instead of butter, and maybe limit the amount of bacon or use turkey bacon.
