Puree Options

  1. Using an immersion blender, blend right in the pot until smooth and silky.
  2. Puree in a blender in small batches. Pour a couple ladles of soup into blender and purée, pour puréed soup into another pot or large bowl until all soup is blended, return pureed soup to pressure cooker pot.
  3. Have a Vitamix? Pour the soup into blender (if the container is large enough, if not, do in batches), turn Vitamix to low speed, then slowly increase the speed until smooth and steamy.
  4. After the soup is puréed, pour in your half and half (coconut milk, heavy cream or whole milk may be substituted), stir until combined.
  5. Taste and adjust seasonings, if needed.


  1. Pour in a little swirl of sour cream (see notes), chopped chives or green onions and crisp bacon, all optional, but adds a lovely touch.

Serving Suggestions

For a light lunch, serve with a slice of warm, buttered  hearty bread. Or add a fresh salad or make a grilled cheese using fresh bread with some smoked gouda, cheddar or Gruyère cheese. 


PRESENTATION TIP | If you want pretty swirls and “dots” of sour cream in your soup; stir the sour cream (plain yogurt or crème fraîche) well and pour into baggie. Snip the corner off and using like a pastry bag, swirl in desired pattern or use a skewer or knife to swirl around.
