Black Bean Soup with Roasted Poblano Chiles

Preparation

1. Step 1

   Preheat broiler. Broil poblano chiles on a foil-lined baking sheet, turning occasionally, until blackened, 8–10 minutes. Transfer to a bowl, cover with plastic wrap, and let steam 15 minutes. Peel, seed, and finely chop.

   Step 2

   Meanwhile, toast seeds in a small dry skillet over medium-high heat, tossing occasionally, until golden, about 5 minutes; transfer to a plate. Toast pasilla chile in same skillet until slightly darkened and pliable, about 1 minute; transfer to plate.

   Step 3

   Heat oil in a medium saucepan over medium-high heat. Add onion and garlic and cook, stirring occasionally, until onion is soft and golden brown, 8–10 minutes. Transfer to a blender, add tomatoes and pasilla chile, and blend until smooth.

   Step 4

   Return tomato mixture to saucepan and cook over medium-high heat, stirring often, until thick, 6–8 minutes. Stir in broth; season with salt. Bring to a boil, reduce heat, and simmer until soup is slightly thickened, 10–15 minutes. Stir in black beans and poblano chiles. Cook, stirring occasionally, until warmed through, about 5 minutes.

   Step 5

   Serve soup topped with queso fresco and pumpkin seeds, with lime wedges alongside.

   Step 6
