Preheat your oven to 400 degrees
Wash and dry all vegetables.
Coat the potatoes with extra virgin olive oil and place them on a large rimmed tray in the oven for 15 minutes.
After 15 minutes, add the peppers to the tray and set the timer for 20 minutes.
After 20 minutes, turn the vegetables over and add cut tomatoes. Roast for an additional 30 minutes.
Remove the tray from the oven. Place the peppers in a bowl and cover with plastic wrap to sweat for easy skin removal.
Once cooled, remove the charred skin from the peppers using a paper towel and season with salt and pepper.
Sauté onions in olive oil in a dutch oven over medium heat for about 5 minutes until translucent. Add garlic and cook for about 1 minute.
Add bay leaf, broth, lovage, roasted potatoes, tomatoes, peppers, and their juices. Simmer for 20 minutes.
Remove from heat, discard the bay leaf, and blend the soup to a smooth consistency with a blender or immersion blender.
Ladle into bowls, and top with torn basil leaves. Enjoy!
