Heat the olive oil in a large pot over medium heat. Add the diced onion and sauté for about 5 minutes until softened.
Stir in the minced garlic and cook for an additional 1 minute, until fragrant.
Add the chicken pieces to the pot, and season with cumin, chili powder, smoked paprika, salt, and pepper. Cook for about 5-7 minutes, stirring occasionally until the chicken is browned.
Pour in the chicken broth and bring the mixture to a simmer. Allow it to cook for 10-12 minutes, until the chicken is fully cooked and tender.
Stir in the black beans, corn, and heavy cream. Simmer for an additional 5-7 minutes, letting the flavors meld together. Adjust seasoning to taste.
Serve the soup hot in bowls, garnished with crispy tortilla strips, chopped cilantro, and a squeeze of lime juice.
For added spice, consider adding diced jalapeños or a pinch of cayenne pepper.
This soup can be made ahead of time and refrigerated; just be sure to store the tortilla strips separately to keep them crispy.
Feel free to top with shredded cheese or avocado for extra richness.
