I melt the butter in the pot, then add onion and chopped poblano with half of the seasoning blend. I sauté them for about 5–6 minutes until they’re soft and lightly browned.
Next, I stir in the shredded chicken, black beans, frozen corn, chicken broth, and remaining seasoning blend. I bring it up to a simmer over medium-high heat and let it simmer (uncovered) for about 15 minutes to let flavors meld.
Once the simmer has done its job, I lower the heat and stir in the heavy cream and shredded cheese until melted and smooth. I bring it back to a gentle simmer, then let it cook for another 15 minutes so everything blends.
Just before serving, I squeeze in fresh lime juice, taste and adjust salt/pepper. Then I ladle into bowls, top with chopped cilantro (and extra cheese or tortilla strips if I’m feeling fancy).
