Pollo alla Romana (Chicken Braised with Peppers in Tomato Sauce)

Pollo alla Romana is a Roman-style chicken braise where bone-in thighs cook slowly with sweet peppers, onion, garlic, rosemary, white wine and tomato passata. Browning the chicken first gives the sauce a deeper savoury base, while gentle simmering keeps the meat tender and lets the peppers soften into the rich tomato juices. The dish is rustic, aromatic and practical: substantial enough for dinner, but made in one pot with a sauce that asks for crusty bread, polenta, rice or another simple starch to soak it up.

Why this recipe works

  • Deep savoury base: Browning the chicken and then deglazing with white wine pulls the caramelised pan juices into the tomato sauce.
  • Gentle braising: A slow simmer keeps the chicken tender while the peppers soften and sweeten into the sauce.
  • Rich, spoonable sauce: Passata, rosemary and the chicken juices create a generous sauce that works well with bread, potatoes, rice or polenta.

Authenticity notes

  • Roman-style braise: This dish follows the familiar Roman pairing of chicken, peppers and tomato, cooked as a rustic home-style main rather than a refined restaurant plate.
  • Built for the table: The chicken is usually served directly with its peppers and sauce, making bread or a simple starch an important part of the meal.

Ingredient notes

  • Use bone-in thighs: Bone-in, skin-on thighs stay moist through the braise and add body to the sauce as they simmer.
  • Choose good passata: Because the sauce is simple, a smooth, well-balanced passata makes a noticeable difference to the final flavour.
  • Rosemary matters: Fresh rosemary gives the cleanest herbal flavour, but dried rosemary can work if added with the garlic so it has time to soften.

Common mistakes

  • Crowding the chicken: Brown the thighs in batches if needed; overcrowding traps steam and prevents the skin from taking on colour.
  • Simmering too hard: Keep the sauce at a gentle simmer so it reduces steadily without catching on the base of the pot.
  • Submerging the skin fully: Nestle the chicken mostly into the sauce but leave the skin exposed to help preserve a better texture.

Make-ahead tips

  • Good the next day: The sauce develops well after resting, making this a useful make-ahead dinner.
  • Reheat gently: Warm in a covered pot over low heat until piping hot, adding a splash of water if the sauce has thickened too much.
  • Freezer suitable: Cool completely before freezing, then defrost overnight in the fridge before reheating gently.

  1. Slice the onion and peppers, and thinly slice the garlic. Strip the rosemary leaves from the sprigs and keep the sprigs to one side.
  2. Pat the chicken dry, then season all over with the salt and pepper. Heat the olive oil in a Dutch oven over medium-high heat.
  3. Brown the chicken, skin-side down first, until deeply golden, 5–7 minutes per side. Work in batches if needed so the pan is not crowded, then transfer the chicken to a plate.
  4. Lower the heat to medium and add the onion and peppers to the pot. Cook, stirring, for 8–10 minutes until softened and lightly caramelised.
  5. Stir in the garlic and rosemary leaves and cook for 1 minute until fragrant. Pour in the wine and simmer for 2–3 minutes, scraping up any browned bits from the base of the pot.
  6. Add the passata and the reserved rosemary sprigs, then bring to a gentle simmer. Nestle the chicken back into the sauce, skin-side up, so it sits mostly submerged but the skin stays exposed.
  7. Cover and simmer gently for 30 minutes, then uncover and continue to simmer for 15 minutes until the chicken is tender and the sauce is thick enough to coat the back of a spoon. Taste and adjust seasoning with a little more salt and pepper if needed.
  8. Rest off the heat for 5 minutes, then discard the rosemary sprigs. Serve hot with plenty of sauce spooned over the chicken and peppers.

Tips

  • Keep the simmer gentle so the sauce reduces without catching; if it starts to stick, lower the heat and stir more often.
  • For a richer finish, spoon a little of the sauce over the chicken skin just before serving to glaze it, while keeping most of the skin above the liquid during braising.

Substitutions

  • Replace Dry White Wine with the same amount of water for an alcohol-free version; simmer it a little longer uncovered to concentrate the sauce.
  • Replace Fresh rosemary with 1 tsp dried rosemary, added with the garlic.

Storage

  • Refrigerate up to 3 days
  • Cool completely, then refrigerate in a sealed container for up to 3 days. Reheat gently in a covered pot over low heat until piping hot, adding a splash of water if the sauce has thickened too much; freeze for up to 2 months and defrost overnight in the fridge before reheating.
