Heat the olive oil in a large pot or Dutch oven over medium heat.
Add the diced onion and sauté for about 5 minutes until it becomes translucent.
Add the minced garlic and cook for another 1-2 minutes until fragrant.
Cut the chicken breasts into bite-sized pieces and add them to the pot. Cook until they are no longer pink, about 5-7 minutes.
Stir in the diced green chilies, chicken broth, cumin, chili powder, paprika, salt, and black pepper. Bring the mixture to a boil.
Reduce heat and let it simmer for 20 minutes. If using white beans, add them during the last 5 minutes of cooking.
Once cooked, stir in the heavy cream to add creaminess to the chili. Adjust seasoning as needed.
Serve hot, garnished with fresh cilantro and sliced jalapeños if desired.
