Preheat oven to 400 degrees F.
Place garlic on a piece of foil and spoon 3 tablespoons of olive oil on top of cut garlic.
Wrap tightly to make a pouch and put directly into the oven for 45 minutes or until garlic is soft.
Once cool enough, squeeze cloves into a pot and add chicken stock.
Cook on high for 10 minutes or until stock reduces by half.
Add cream.
Using an immersion blender, puree until smooth and continue to cook on low.
