Creamy Roasted Tomato Soup with Garlic and Basil

This silky Roasted Tomato Soup is made from oven-roasted, herb-scented tomatoes finished with a splash of cream and served with a simple cheesy bread. The roasted tomato and thyme soup is velvety, bright, and comforting—perfect for cool, rainy days.

Lately there hasn’t been much baking, just the occasional lemon drizzle cake and a few cookies, but fall is settling in and soups are back on the table. Roasting tomatoes concentrates their sweetness and adds a subtle smokiness that transforms a basic tomato soup into something special.

On a rainy afternoon, with the sky grey and the mood wanting color, I roasted a batch of tomatoes with onion, garlic, thyme, a touch of sugar, and olive oil. While those flavors caramelized in the oven, I warmed stock and finished the soup with a little cream for silkiness. A thick slice of sourdough was toasted in butter, topped with torn fresh mozzarella, and broiled until bubbly and golden. The result was a bowl of sunset-red soup crowned by melty cheese and fresh chives—simple, satisfying, and memorable.

This roasted tomato soup is closely related to a roasted tomato sauce, but with a creamier finish and a looser, spoonable texture. The roasting step brings out concentrated tomato flavor and a touch of sweetness; the thyme and roasted garlic add herbal depth and a faint savory smoke. The cheesy toast gives each spoonful a delightful contrast of crisp, oozy, and herb-fresh notes.

To prepare the soup, halve ripe tomatoes and quarter an onion, leave the garlic cloves in their skins with the tops trimmed, and scatter everything on a baking tray with fresh thyme. Sprinkle a little sugar to encourage caramelization, season with salt and pepper, drizzle with olive oil, and roast until the tomatoes are reduced and syrupy. Pulse or blend the roasted vegetables until smooth, then warm the mixture in a saucepan with stock and a splash of cream until it reaches the desired consistency.

For the cheese-topped bread, heat a cast-iron or oven-safe skillet, butter the bread and toast both sides until golden, then top with torn fresh mozzarella and finish under a hot broiler until the cheese is bubbling and browned. Float the cheesy toast on the hot soup and finish with chopped chives for a bright, oniony lift.

Serve the warm soup in bowls with the cheesy bread perched on top. The texture is creamy and velvety, with a natural sweetness from the roasted tomatoes and a whisper of smokiness from the garlic. The mozzarella-topped toast adds richness and a satisfying bite. This recipe makes about two generous servings, but it scales well—double or triple the ingredients when you want to feed more or save leftovers.
