2 tablespoons chipotle in adobo sauce, or to taste
1 (28-ounce) can whole peeled tomatoes
2 teaspoons salt, or to taste
2 teaspoons black pepper, or to taste
¼ cup heavy whipping cream
Directions
Make the stock: Combine the chicken, celery, carrot, onion, and oregano in a large pot. Cover with 8 cups water.
Bring to a simmer and cook until the chicken is pull-apart tender, about 30 minutes. Do not boil.
Remove the chicken from the pot. Remove the skin, shred, and reserve the meat.
Strain the remaining stock through a fine mesh strainer, pressing down on the solids. Reserve the stock.
Make the bisque: Melt the butter in a large pot over medium heat.
Add the diced onion, garlic, and bell pepper and cook until softened, about 5 minutes.
Sprinkle with the flour and stir until a paste forms. Do not burn.
Slowly whisk in the reserved chicken stock until no lumps remain.
Add the chipotle in adobo, tomatoes, salt, and pepper.
Bring to a boil, then reduce the heat and simmer for 20 minutes.
Add the heavy cream and transfer the soup to a blender, working in batches, as needed. Cover the blender opening with a towel and blend until smooth. Alternatively, use an immersion blender.
Pour the blended soup through a chinois strainer into a pot, using a ladle to push the soup through.
Return the shredded chicken to the soup to warm it through.
To serve, garnish with cilantro and tortilla strips, if desired.
