1head garlicabout ¼-inch cut off top to expose cloves
1medium yellow onionchopped
3tablespoonstomato paste
2cans(14 ounces each) low-sodium chicken broth
1teaspoonkosher salt
½teaspoonfreshly ground pepper
Instructions
Heat oven to 425°F. In a rimmed baking sheet, liberally brush eggplant and tomatoes with oil; arrange eggplant cut side down and tomatoes cut side up. Brush cut side of garlic head with oil and wrap in foil-nestle on the pan next to the other vegetables.
Roast vegetables and garlic until vegetables are tender and browning in spots, about 45 minutes. Let stand until eggplant is cool enough to handle, about 20 minutes; peel eggplant and discard skin.
Meanwhile in a large pot, heat oil over medium-low heat. Add onion and cook until softened, 10 to 12 minutes. Stir in tomato paste and cook 2 minutes. Add eggplant and tomatoes. Squeeze roasted garlic from skins into vegetables; stir to combine. Stir in broth, salt and pepper; bring to a simmer and cook 5 minutes. Purèe using an immersion blender or a food processor.
Notes
Roast the eggplant fully. Eggplant should be deeply caramelized and completely tender before blending. If it’s pale or under-roasted, the soup won’t have the same smoky depth or creamy texture.
