Brown the Chicken (Don’t Skip This!)
Pat chicken dry and season generously with salt and pepper.
Heat olive oil in a large Dutch oven or deep skillet over medium-high heat.
Add chicken skin-side down and cook 5–6 minutes per side, until deeply golden.
Remove chicken and set aside.
Build the Flavor Base
Lower heat to medium. Add onions and celery to the same pan.
Cook 4–5 minutes until softened and lightly golden.
Stir in bell peppers and garlic. Cook 2 minutes until fragrant.
Sprinkle in red pepper flakes.
Deglaze with Red Wine
Pour in red wine, scraping up all those browned bits.
Let simmer 3–4 minutes until slightly reduced.
Simmer the Sauce
Add crushed tomatoes, tomato paste, oregano, thyme, and bay leaf.
Stir well and bring to a gentle simmer.
Braise the Chicken
Nestle chicken back into the sauce, skin-side up.
Cover and simmer on low 35–45 minutes, until chicken is tender.
Uncover for the last 10 minutes to thicken the sauce.
Finish and Taste
Remove bay leaf.
Taste and adjust seasoning with salt and pepper.
Sprinkle with parsley and basil.
