Step 1: Prep the Chicken
Season: Generously season the chicken thighs with salt and pepper on both sides.
Brown the Chicken: Heat 2 tablespoons of olive oil in a large skillet or Dutch oven over medium-high heat. Add the chicken, skin side down, and sear until golden brown (about 5-6 minutes per side). Remove the chicken and set it aside.
Step 2: Sauté the Vegetables
Cook the Aromatics: In the same skillet, add the chopped onion, garlic, carrot, celery, and bell pepper. Cook for about 5-7 minutes until softened, stirring occasionally.
Deglaze with Wine: Pour in the white wine (or chicken broth) to deglaze the pan, scraping up any flavorful brown bits stuck to the bottom.
Step 3: Build the Sauce
Add Tomatoes and Herbs: Stir in the crushed tomatoes, tomato paste, oregano, bay leaf, and optional chili flakes. Mix everything together to combine.
Simmer: Return the browned chicken to the skillet, skin side up, and add the chicken broth. Bring the sauce to a simmer, then reduce the heat to low. Cover the pan and let the chicken cook for about 30-35 minutes, until it’s fully cooked through and tender.
Step 4: Finishing Touches
Adjust the Seasoning: Taste the sauce and add more salt, pepper, or chili flakes as needed. Remove the bay leaf.
Garnish: Sprinkle with fresh parsley before serving.
