Prep the tortilla strips: Preheat your oven to 400°F (200°C). Toss the tortilla strips with a light spray or drizzle of oil and a pinch of salt. Spread on a baking sheet and bake for 6–10 minutes, stirring once, until crisp and lightly golden.
Set aside.
Sauté the aromatics: Warm 1 tablespoon olive oil in a large pot over medium heat. Add the onion and cook 4–5 minutes until softened. Stir in garlic and jalapeño, cook 30 seconds until fragrant.
Bloom the spices: Add cumin, chili powder, smoked paprika, salt, and pepper.
Stir for 30–60 seconds. This unlocks the spices’ flavor.
Build the base: Stir in the tomato paste (if using), then add fire-roasted tomatoes, green chiles, and chicken broth. Bring to a gentle boil.
Cook the chicken: Nestle the chicken breasts into the pot.
Reduce heat to a steady simmer, cover, and cook 12–16 minutes, or until the chicken is just cooked through and reaches 165°F (74°C).
Shred the chicken: Transfer chicken to a plate and shred with two forks. Return the chicken to the pot.
Add the beans and corn: Stir in black beans and corn. Simmer uncovered for 5–10 minutes to meld flavors.
Adjust salt and pepper to taste.
Finish bright: Turn off heat. Stir in lime juice and cilantro. Taste and add more lime or salt if needed.
Serve: Ladle into bowls.
Top with a handful of crispy tortilla strips and any extras you like—avocado, a dollop of Greek yogurt, a sprinkle of cheese, and more cilantro.
