Meanwhile, in 5-quart Dutch oven, heat oil over medium high-heat. Add 2 cloves garlic, the onion and baguette. Cook 1 to 2 minutes, stirring occasionally, until vegetables are slightly softened. In blender, place 2 cups broth, the baguette mixture, 1/4 cup pumpkin seeds and the sugar. Cover; blend on medium speed, stopping blender frequently to scrape down sides, until pureed.
