Ingredients
1 tablespoon extra-virgin olive oil
1 small onion, chopped
2 garlic cloves, smashed and peeled
Coarse salt and ground pepper
1 teaspoon ground cumin
1/2 teaspoon ground coriander
4 cups Whole Roasted Tomatoes
1/2 teaspoon sugar
1 tablespoon unsalted butter
Fresh cilantro leaves, for serving
Red-pepper flakes, for serving
Preparation
In a medium saucepan, heat oil over medium. Add onion and garlic and season with salt and pepper. Cook, stirring occasionally, until onion is soft, about 12 minutes. Add cumin and coriander; cook, stirring, until fragrant, about 30 seconds. Add tomatoes, sugar, and 1 cup water and cook until warmed through, about 5 minutes. In batches, puree soup in a blender until smooth (use caution when blending hot liquids). Strain through a fine-mesh sieve. Stir in butter and season with salt and pepper. Serve soup with cilantro and red-pepper flakes.
