Heat olive oil in a large pot over medium heat. Add onion and garlic, and sauté for 3–4 minutes until soft and fragrant.
Add diced jalapeños, chili powder, cumin, and smoked paprika. Cook for another minute to toast the spices.
Pour in the fire-roasted tomatoes, chicken broth, black beans, and corn. Stir to combine.
Add shredded chicken and bring to a simmer. Let cook for 15–20 minutes.
Optional: Use an immersion blender to partially blend for a thicker texture.
Stir in fresh lime juice. Taste and adjust seasoning with salt and pepper.
Serve hot with tortilla strips and your favorite toppings.
