This vibrant black bean soup with roasted poblano chillies is a deeply flavoured vegetarian dish that brings a touch of Mexican warmth to the table. By charring the peppers and toasting dried chillies, you create a complex, smoky base that perfectly complements the creamy texture of the black beans. The addition of fire-roasted tomatoes adds a subtle sweetness, while a squeeze of fresh lime juice right before serving cuts through the richness for a perfectly balanced bowl.
Ideal for a nutritious midweek dinner or a weekend lunch, this soup is both comforting and heart-healthy. You can easily prepare the base up to two days in advance, making it a brilliant option for those who enjoy batch cooking. Garnish with salty feta or queso fresco and crunchy pumpkin seeds to add a delightful contrast in texture and flavour. Serve with warm corn tortillas or crusty bread for a complete, satisfying meal.

How to make Black Bean Soup with Roasted Poblano Chillies
Back to contentsPreheat grill. Grill poblano chillies 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.
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 chilli in same skillet until slightly darkened and pliable, about 1 minute; transfer to plate.
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 chilli, and blend until smooth.
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 chillies. Cook, stirring occasionally, until warmed through, about 5 minutes.
Serve soup topped with queso fresco and pumpkin seeds, and with lime wedges alongside.
DO AHEAD: Soup can be made 2 days ahead. Cover and chill.
