Make this Creamy Pressure Cooker Cauliflower Potato Soup. Comforting, thick cauliflower soup is smooth, yet stacked with layers of umami flavors. A budget-friendly, low-carb pressure cooker soup that you’ll enjoy even on a warm day! 😀
Optional: freshly grated Parmesan cheese for garnish
Crisp the Bacon: Place chopped bacon in your Pressure Cooker and turn heat to medium (Instant Pot: press Sauté button). Stir occasionally and allow the bacon bits to crisp (~4 mins). Remove bacon bits from pressure cooker and place on paper towel to absorb the excess fat.
Sauté the Onion, Garlic, and Green Onions: Sauté onions in bacon fat for roughly 1 – 2 minutes until soften. Add in garlic and half of the green onions. Season with a pinch of kosher salt and pepper if you like. Sauté until fragrant.
Deglaze: Pour ~ ⅓ cup (100 ml) unsalted chicken stock. Scrub all the brown bits off the bottom of the pot with a wooden spoon. Keep the brown bits as they are very flavorful.
Pressure Cook the Cauliflower Potato Soup: Add 2 bay leaves, cauliflower, and 2 red potatoes in the pressure cooker. Pour the remaining chicken stock into pressure cooker. Close the lid and cook at High Pressure for 3 minutes. Turn off the heat and do a 10 minutes Natural Release. Open the lid carefully.
Remove Bay Leaves (Optional): If you don't think your immersion hand blender is powerful enough to blend through the bay leaves, you can remove them at this step.
Blend & Season: Blend cauliflower soup into desired consistency with an immersion hand blender. Add 1 cup (250 ml) of heavy cream. Taste the soup and season with 2 tablespoons (30 ml) of fish sauce and kosher salt.
Serve: Garnish with green onions, crispy bacon bits, and freshly grated Parmesan cheese. Enjoy immediately. I think you will love it 🙂
Thinner Consistency: If you like a thinner soup consistency, add hot homemade unsalted chicken stock to adjust the thickness of the soup.
Smaller Cauliflower Florets: break the larger pieces into smaller florets, so it'll be easier to blend.
Crispy Bacon: It's important to place the bacon in the cold pot before turning on the heat (see tips section in the article).
