In a large pot or Dutch oven, heat the olive oil over medium heat.
Add the diced onion and sauté for about 3-4 minutes until softened.
Stir in the minced garlic and cook for an additional 1 minute.
Add the ground turkey to the pot and cook, breaking it apart with a spoon, until browned (approximately 5-6 minutes).
Incorporate the diced bell pepper, carrots, and celery into the mixture, cooking for another 5-6 minutes until the vegetables soften.
Stir in the kidney beans, black beans, crushed tomatoes, chili powder, cumin, smoked paprika, salt, and black pepper. Mix well to combine.
Pour in the chicken broth, stirring to combine everything. If you prefer a thinner consistency, add more broth as needed.
Bring the chili to a boil, then reduce the heat to low. Cover and let simmer for 30 minutes, stirring occasionally.
Taste and adjust seasoning if necessary. Add optional toppings before serving, if desired.
