Preheat oven to 425 degrees F and line two baking sheets with foil.
Slice carrots, onion and tomatoes in circles. Lay tomatoes in one pan and the rest of the veggies in the other. Toss in garlic cloves with the peel on.
Drizzle olive oil and sprinkle brown sugar and a pinch of salt evenly and give the veggies a toss. The brown sugar will help the veggies caramelize and bring out the sweetness.
Bake for 35-40 minutes. The tomatoes take a little more time so take out the pan with the carrots, onions and garlic early if they look nice and roasted.
In a pot oven medium heat, melt butter.
Next, squeeze out the roasted garlic pulp out of the husk and stir for a few seconds.
Next add tomato paste and crushed chili and stir for a few seconds to bring everything together.
Tip all the roasted veggies into the pan. Scrape using a spoon if they are stuck to the foil. The charred bits are the best! Make sure you don't accidentally add in the foil as you scrape.
Add in basil leaves along with chicken stock. Let simmer gently for 3-4 minutes to allow the flavors to infuse together.
Now puree everything until smooth. If you have an immersion blender, that will work beautifully!
Now pour the pureed soup back into the saucepan, add in cream, a few basil leaves and stir.
let the soup simmer for another 5 minutes
Pour your tomato basil soup into bowls and top with a basil leaf and serve alongside a slice of baguette.
