Total Time 40 mins

Ingredients

  • 1 head cauliflower , floret
  • 2 small red potatoes , chunked
  • 4 cups (1L) unsalted chicken stock
  • 6 cloves garlic , minced
  • 6 slices bacon , chopped
  • 1 medium onion , diced

  • 2 tablespoons (30ml) fish sauce (optional)

Instructions

  • Crisp Bacon: Place chopped bacon in your Instant Pot, then turn heat to medium (press "Sauté" button). Stir occasionally, then allow the bacon bits to crisp (~4 mins). Remove bacon bits from Instant Pot, then place them on a paper towel to absorb the excess fat.
  • Sauté Onion, Garlic, Green Onions: Sauté onions in bacon fat for ~1 – 2 mins until softened. Add in garlic and half of the green onions. Season with a pinch of kosher salt and pepper. Sauté until fragrant.
  • Deglaze: Pour ~cup (100ml) 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 Cauliflower Potato Soup: Add 2 bay leaves, cauliflower, and 2 red potatoes in Instant Pot. Pour the remaining chicken stock in Instant Pot.
    Close the lid and pressure cook at High Pressure for 3 minutes, then 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 tbsp (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 ;)

Notes

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).
