Prepare the vegetables. Remove the papery skin and slice the garlic cloves, peel the potatoes and chop them as well as the onion.
In a large deep pot, heat up olive oil on medium high heat then add the chopped onions and sauté for 3 to 5 minutes or until they are translucent.
Add the sliced or diced garlic and sauté just until it releases its fragrance.
Add the potato chunks followed by your vegetable broth. Let this cook for 20 minutes or until the potatoes are fork tender.
Once the potatoes are cooked, you can remove the soup from the heat. Use an immense blender to blend the soup.
Add cream to the garlic soup and do a taste test, if you need to add salt go ahead.
Finely chop the coriander and add it to the pot of soup and give it a good stir. Your garlic soup is ready to be served.
