Place the leek and the sliced broccoli core in a pot and cover with water Add bouillon cube Season with salt, and bring to a boil for a few minutes on high heat until the broccoli stem is just easily pierced with a knife.
Add the broccoli florets Lower the heat and simmer for a few minutes, until the broccoli is bright green and tender Add cream cheese, cream, freshly ground pepper, basil and garlic.
