Why This Recipe Works

Roasting fresh tomatoes, onions, red pepper, and garlic cloves before pureeing them with vegetable broth brings depth to this simple soup. The unpeeled garlic turned creamy and mellow in the oven, and it was easy to squeeze the roasted cloves from their skins before adding them to the blender. A couple tablespoons of butter pureed with the vegetables added richness and body. To garnish the soup, we made cheesy croutons by creating a layer of crispy cheddar frico on both sides of two slices of bread and then cutting them into 1-inch pieces.
