Costillas de Cerdo a la Riojana (Rioja-Style Pork Ribs with Peppers)

Rioja-style pork ribs are a slow-simmered Spanish stew of bone-in pork, sweet peppers, tomato and paprika, cooked until the meat turns tender and the sauce becomes glossy and concentrated. The dish has the generous, rustic character of casserole cooking: browned ribs give depth, softened onion and red pepper melt into the juices, and sherry vinegar sharpens the rich, smoky finish. It is the kind of savoury main that suits simple accompaniments best, especially potatoes or crusty bread for catching the peppery tomato sauce.

Why this recipe works

  • Layered savoury base: Browning the ribs first creates depth, while softened onion, pepper, garlic, tomato and smoked paprika build a rich Spanish-style sauce.
  • Slow, gentle braise: A covered simmer gives the bone-in ribs time to become tender while the cooking juices flavour the sauce.
  • Bright finish: Sherry vinegar added at the end cuts through the richness and keeps the tomato-pepper sauce lively.
  • One-pot depth: The ribs, vegetables and sauce cook in the same pot, so the browned bits are folded back into the braise instead of being lost.

Authenticity notes

  • Rioja-style flavour base: This style leans on peppers, tomato, garlic and paprika for a rustic sauce that suits pork and slow braising.
  • Home-style serving: The saucy finish is meant for simple sides such as potatoes or crusty bread rather than elaborate accompaniments.

Ingredient notes

  • Use smoked paprika carefully: Smoked paprika gives the sauce its warm, smoky character, but it should be stirred in briefly so it blooms without turning bitter.
  • Add vinegar at the end: Sherry vinegar works best as a finishing note, brightening the sauce once the ribs are tender and the glaze has reduced.
  • Ripe tomatoes help the sauce: Ripe tomatoes break down more easily and give the braise a fuller, rounder base.

Common mistakes

  • Do not scorch the paprika: Add the paprika after the vegetables have softened and keep it moving briefly before the tomatoes and stock go in.
  • Avoid a hard boil: A vigorous boil can toughen the ribs and make the sauce catch; keep the braise at a low, steady simmer.
  • Reduce the sauce uncovered: If the sauce is still loose once the ribs are tender, simmer uncovered until it lightly coats the meat.

Make-ahead tips

  • Good made ahead: The braise holds well overnight, and the sauce often tastes rounder after resting in the fridge.
  • Reheat gently: Warm in a covered pan over low heat with a splash of water if the sauce has thickened too much.
  • Freezes well: Cool completely before freezing, then defrost in the fridge before reheating until piping hot.

  1. Cut the ribs into individual pieces if needed. Slice the onion and peppers, and roughly chop the tomatoes. Peel and thinly slice the garlic.
  2. Heat the olive oil in a large casserole over medium-high heat. Season the ribs with the salt and black pepper, then brown in batches for 6 to 8 minutes, turning, until well coloured. Transfer to a plate.
  3. Lower the heat to medium and add the onion and peppers to the pot. Cook for 8 to 10 minutes, stirring, until softened and starting to take on colour. Stir in the garlic for 1 minute until fragrant.
  4. Stir in the smoked paprika and cook for 20 seconds so it blooms without burning. Add the tomatoes and cook for 5 minutes, stirring, until they begin to break down. Pour in the chicken stock and add the bay leaves, scraping up any browned bits.
  5. Return the ribs and any juices to the pot and bring to a gentle simmer. Cover and cook on low for 60 minutes, stirring once or twice, until the ribs are tender. If it looks dry at any point, add a splash of water to keep it saucy.
  6. Uncover and simmer for 10 to 15 minutes until the sauce reduces and lightly glazes the ribs. Stir in the sherry vinegar and simmer for 1 minute, then taste and adjust seasoning if needed. Rest off the heat for 2 minutes before serving.

Tips

  • Keep the simmer gentle so the ribs turn tender without the sauce catching on the base of the pot.
  • If you prefer a smoother sauce, lift out the ribs once tender, blend the sauce, then return the ribs to glaze for the final simmer.
  • For vulnerable groups, ensure the pork is cooked until piping hot throughout and the meat is tender and pulling from the bone.

Substitutions

  • Replace Sherry vinegar with red wine vinegar for a similar tang.
  • Replace Chicken stock with vegetable stock for a lighter, less meaty base.

Storage

  • Refrigerate up to 3 days
  • Cool completely, then refrigerate in a sealed container for up to 3 days. Reheat gently in a covered pan over low heat with a splash of water until piping hot. Freeze for up to 2 months; defrost overnight in the fridge before reheating.
