Creamy Chicken Poblano Soup is loaded with smoky roasted poblano peppers, tender chicken, fire-roasted corn and black beans in a rich, velvety broth. Inspired by the Chicken Poblano Soup at Chicken Salad Chick, this easy homemade version is hearty, flavorful and perfect for a cozy weeknight dinner.
Arrange the poblano peppers on a baking sheet and place under the broiler. Broil for 4-5 minutes per side, turning as needed, until the skins are blistered and charred.
Transfer the hot peppers to a bowl and cover. Let them steam for 10 minutes, then peel away the loosened skin. Remove the stems and seeds, then dice the peppers.
Heat the olive oil and butter in a large Dutch oven or stockpot over medium heat. Add the onion and cook for 4-5 minutes, until softened and translucent. Stir in the garlic and cook for about 30 seconds, until fragrant.
Sprinkle the flour over the onions and stir constantly for 1 minute. Slowly whisk in the chicken stock until smooth.
Stir in the roasted poblanos, cumin, smoked paprika, salt, black pepper and cayenne, if using. Bring to a gentle simmer and cook for 8-10 minutes.
Reduce the heat to medium-low. Stir in the half-and-half and milk and heat gently until the broth is creamy and steaming. Do not allow the soup to come to a hard boil.
Stir in the cooked chicken, fire-roasted corn and black beans. Continue to simmer gently for 8-10 minutes, until everything is heated through and the broth has thickened slightly.
Remove the pot from the heat. Stir in the lime juice, lime zest and cilantro, if using. Taste and adjust the salt and pepper.
Ladle into bowls and serve hot. Garnish with cilantro, sliced poblano, tortilla strips or lime wedges, if desired.
Notes
• Poblanos vary in heat. Most are mild, but occasionally you'll get a spicier pepper. Leave out the cayenne if you want to keep the soup especially mild.• Rotisserie chicken is my favorite shortcut. Leftover roasted, grilled or poached chicken works just as well.• For a thicker soup, increase the flour to 1/3 cup or reduce the chicken stock to approximately 3 1/2 cups.• For an extra-creamy texture without adding more dairy, blend about 1 cup of the finished soup until smooth and stir it back into the pot.• If you can't find fire-roasted corn, regular frozen corn works perfectly. For more smoky flavor, quickly char it in a dry skillet before adding it to the soup.• Once the dairy has been added, keep the soup at a gentle simmer rather than a full boil to help the broth stay smooth.• Store leftovers in an airtight container in the refrigerator for up to 3-4 days.• Freeze cooled soup for up to 2 months. Thaw overnight in the refrigerator and reheat gently, whisking if needed to bring the creamy broth back together.
