Season the chicken: Pat the thighs dry with paper towels. Sprinkle all over with salt, pepper, and smoked paprika. This helps the skin crisp and flavors the meat throughout.
Brown the chicken: Heat olive oil in a large Dutch oven over medium-high.
Place the thighs skin-side down and sear 6–8 minutes until deeply golden. Flip and cook 2–3 minutes more. Transfer to a plate.
Don’t rush this step; color equals flavor.
Build the aromatics: Reduce heat to medium. Add the onion and a pinch of salt. Cook 3–4 minutes until softened, scraping brown bits from the pot.
Stir in the garlic and cook 30–45 seconds until fragrant.
Tomato base: Add tomato paste and red pepper flakes. Cook, stirring, 1–2 minutes to caramelize the paste slightly; it should darken a shade.
Deglaze: Pour in the white wine. Simmer 1–2 minutes, scraping the bottom to release any fond.
If not using wine, use broth and add a squeeze of lemon at the end for brightness.
Simmer the sauce: Stir in crushed tomatoes, chicken broth, oregano, thyme, and the bay leaf. Bring to a gentle simmer. Taste and add a little sugar or honey if the sauce is very acidic.
Return the chicken: Nestle the thighs back into the pot, skin-side up.
The skin should sit mostly above the liquid so it stays somewhat crisp. Reduce heat to low, cover, and cook 30 minutes.
Finish uncovered: Remove the lid and simmer another 10–15 minutes to thicken the sauce and finish cooking. Internal temperature should reach 175–185°F for tender, juicy thighs.
Optional richness: Stir in butter to finish the sauce.
Adjust salt and pepper. Remove the bay leaf. Add a squeeze of lemon if you like a brighter finish.
Serve: Sprinkle with chopped basil or parsley.
Serve over polenta, mashed potatoes, rice, or crusty bread. Spoon plenty of sauce on top.
