Wash carrots. Peel the skin on them. Chop them roughly. Chop onions roughly. Slightly crush garlic (skin removed).
Pre heat oven to 360 degree F
Grease a baking sheet with olive oil. Layer the carrots, onion, garlic on the baking sheet in a single layer. Sprinkle rock salt and pepper powder. Drizzle olive oil on top of the carrots and toss once.
Roast in an pre-heated oven for about 30 to 40 minutes. Toss 2 twice in between so carrots cook evenly. Once nicely roasted take it out of the oven and let it cool a bit.
Transfer all to Vitamix and blend smooth. Pour soup back into a sauce pan. Heat the soup until nice hot.
Ladle hot soup into serving bowls, add the garnish and serve immediately.
