Sauté the aromatics: Heat 1–2 tablespoons olive oil in a large pot over medium heat. Add diced onion and a pinch of salt.
Cook until soft and translucent, about 5–6 minutes. Stir in garlic and jalapeño, and cook 1 minute until fragrant.
Bloom the spices: Add cumin, chili powder, smoked paprika, and a few grinds of black pepper. Stir for 30 seconds to wake up the spices without burning them.
Add the base: Pour in chicken broth and add crushed or diced tomatoes.
If using tomato paste, whisk in 1 tablespoon for a richer broth. Bring to a gentle simmer.
Build the body: Stir in black beans and corn. Simmer 10–12 minutes to meld the flavors.
Taste and adjust salt as needed.
Add the chicken: Stir in shredded chicken and simmer another 5–7 minutes, just until heated through and tender. Avoid boiling hard so the chicken stays juicy.
Finish with freshness: Turn off the heat. Stir in fresh lime juice and chopped cilantro.
This brightens the soup and balances the spices.
Serve with crunch: Ladle into bowls. Top with tortilla strips, avocado, sour cream, cheese, and anything else you like. Serve extra lime wedges on the side.
