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

This Instant Pot Low-Carb Loaded Cauliflower Soup is a soup recipe I’ll make over and over, and this tasty soup is also Keto, low-glycemic, gluten-free, and can be South Beach Diet friendly.

Even though I try to share lots of low-carb Super Bowl Recipes, I know some of you definitely had some carb-loaded foods while you were watching the game, am I right? Personally I find special occasions like that to be the hardest time to practice carb-conscious eating, and my family is (cough) not known for bringing low-carb options when I’m hosting either, which I was yesterday.

So if you’re thinking about getting back on track today, I have a real treat for you. This Instant Pot Low-Carb Loaded Cauliflower Soup was absolutely amazing; I promise you that no one will think about low-carb diets while they’re eating this soup.

Ingredients:

• 1/2 onion, chopped small
• 2 T butter or olive oil
• 1 large head of cauliflower, leaves and stem removed and the rest coarsely chopped. (About 7-8 cups chopped cauliflower. You can use the core.)
• 3 cups (24 oz.) chicken stock (I would use flavorful homemade chicken stock, or chicken stock from a carton) 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 sharp or extra sharp cheddar cheese (We used a mix of cheeses, but next time Kara and I agreed we would use mostly extra sharp cheddar.)
• 1/2 cup half and half, cream, or milk

TOPPING INGREDIENTS:

• extra grated sharp cheddar or extra sharp cheddar cheese
• sour cream
• 8-10 strips bacon, cooked crisp and crumbled (We used pre-cooked bacon and cooked it in the microwave.)
• thinly sliced green onions

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.
