Warm the pot: Heat oil in a large pot or Dutch oven over medium heat until shimmering.
Soften the aromatics: Add onion, bell pepper, and jalapeño. Cook 5–6 minutes, stirring, until softened and lightly golden.
Add garlic and spices: Stir in garlic, chili powder, cumin, smoked paprika, and oregano.
Cook 30–60 seconds until fragrant.
Brown the chicken: Add ground chicken. Break it up with a spoon and cook 6–8 minutes until no longer pink. Season with salt and pepper.
Build the base: Stir in tomato paste and cook 1 minute to caramelize slightly.
Simmer: Add crushed tomatoes, chicken broth, cocoa powder (if using), and apple cider vinegar.
Bring to a gentle simmer.
Reduce and thicken: Lower heat and simmer uncovered 20–25 minutes, stirring occasionally, until thickened to your liking.
Taste and adjust: Add more salt, pepper, or chili powder as needed. If it’s too thick, splash in extra broth. If you want more tang, add a squeeze of lime.
Finish: Stir in chopped cilantro if using.
Ladle into bowls and add toppings like cheddar, sour cream, avocado, and green onions.
