Recipe Notes

There are a couple of ways you can puree your roasted tomatoes in this roasted tomato basil soup:

  1. Vitamix- using this will give you the creamiest soup and is my preferred method.
  2. Hand Immersion Blender- This is the second best method, but you will need to be careful since it may get a little messy!  
  3. Food processor- If using a food processor, you will need to puree your soup in batches to prevent splattering.
