Prep the chicken: Pat the chicken pieces dry and season with salt, pepper, paprika, thyme, and rosemary.
Brown the chicken: Heat olive oil or butter in the pot over medium-high heat. Sear chicken pieces until golden brown on all sides. Remove and set aside.
Cook the vegetables: In the same pot, sauté onions, garlic, carrots, celery, and bell pepper until softened (about 5–7 minutes).
Deglaze the pot: Pour in white wine (if using) and scrape the bottom to lift any browned bits. Let it simmer for 2 minutes.
Add chicken and stock: Return the chicken to the pot, add chicken stock, and toss in the bay leaf. Bring to a gentle boil.
Simmer: Reduce heat to low, cover, and simmer for 45–60 minutes, until the chicken is tender and fully cooked. Stir occasionally.
Check seasoning: Taste the sauce and adjust salt and pepper as needed.
Serve: Garnish with fresh parsley and serve hot with rice, mashed potatoes, or crusty bread.
