📝 About This Recipe

Transport your kitchen to the heart of Andalusia with this luxurious Rabo de Toro, a traditional Spanish oxtail stew that transforms a humble cut into a melt-in-your-mouth masterpiece. By utilizing the Instant Pot, we achieve a deep, complex reduction of red wine, aromatics, and collagen-rich beef in a fraction of the traditional simmering time. The result is a silky, bone-clinging sauce and tender meat that tastes like it spent all day on a wood-fired hearth.

🥗 Ingredients

The Meat

  • 3.5 pounds Oxtail (cut into 2-inch segments, trimmed of excess outer fat)
  • 2 teaspoons Kosher Salt (more to taste)
  • 1 teaspoon Black Pepper (freshly cracked)
  • 1/2 cup All-purpose Flour (for dredging)
  • 3 tablespoons Extra Virgin Olive Oil (Spanish oil preferred)

The Aromatics & Base

  • 1 large Yellow Onion (finely diced)
  • 2 large Carrots (peeled and sliced into rounds)
  • 1 large Leek (white and light green parts only, cleaned and sliced)
  • 1 Red Bell Pepper (seeded and diced)
  • 6 cloves Garlic (smashed and minced)

The Braising Liquid & Spices

  • 2 cups Dry Red Wine (Tempranillo or Rioja is best)
  • 1.5 cups Beef Bone Broth (low sodium)
  • 2 tablespoons Tomato Paste (double concentrated)
  • 1 teaspoon Smoked Paprika (Pimentón) (sweet or bittersweet)
  • 2 pieces Bay Leaves (dried)
  • 2 pieces Whole Cloves (optional, for authentic depth)

👨‍🍳 Instructions

  1. 1

    Season the oxtail segments generously with salt and pepper. Dredge each piece in flour, shaking off any excess so only a thin coating remains.

  2. 2

    Select the 'Sauté' function on your Instant Pot and set it to 'High'. Add the olive oil and wait until it is shimmering.

  3. 3

    Working in batches to avoid crowding, brown the oxtail pieces on all sides until a deep, golden-brown crust forms (about 3-4 minutes per side). Remove meat and set aside on a plate.

  4. 4

    In the remaining fat, add the onion, carrots, leek, and red pepper. Sauté for 5-6 minutes until the vegetables begin to soften and the onion turns translucent.

  5. 5

    Stir in the garlic and tomato paste. Cook for 2 minutes, stirring constantly, until the paste turns a dark brick red and smells toasted.

  6. 6

    Pour in the red wine. Use a wooden spoon to scrape the bottom of the pot vigorously to release all the 'fond' (browned bits)—this is where the flavor lives!

  7. 7

    Add the beef broth, smoked paprika, bay leaves, and cloves. Stir to combine.

  8. 8

    Return the browned oxtail and any accumulated juices back into the pot, ensuring the meat is mostly submerged in the liquid.

  9. 9

    Secure the lid and set the valve to 'Sealing'. Cancel the Sauté function and select 'Pressure Cook' (or Manual) on High for 45 minutes.

  10. 10

    Once the timer beeps, allow the pressure to release naturally for 15 minutes before manually releasing any remaining steam.

  11. 11

    Carefully remove the oxtail pieces to a serving platter. Discard the bay leaves and cloves.

  12. 12

    Optional: For a silky restaurant-style finish, use an immersion blender to blend the sauce and vegetables until smooth, or simply simmer the sauce on 'Sauté' for 5-10 minutes to thicken it further.

  13. 13

    Taste the sauce and adjust salt and pepper if needed. Pour the rich gravy over the oxtails and serve immediately.

💡 Chef's Tips

Don't skip the dredging step; the flour on the meat helps thicken the sauce naturally during pressure cooking. If the sauce feels too greasy, use a fat separator or chill the stew overnight to easily lift off the solidified fat cap. For the best flavor, make this a day in advance; the spices and gelatinous textures develop beautifully after a night in the fridge. Always use a wine you would actually drink—a cheap, sour wine will result in a sour sauce. If your oxtail pieces are exceptionally large, add 5-10 minutes to the pressure cooking time.

🍽️ Serving Suggestions

Serve over a bed of creamy mashed potatoes or buttery polenta to soak up the rich sauce. Pair with a side of crispy 'Patatas Fritas' (thick-cut fries) for a truly traditional Spanish presentation. A crusty baguette is essential for cleaning every drop of gravy off the plate. Balance the richness with a glass of bold Spanish Rioja or Ribera del Duero red wine. Garnish with fresh flat-leaf parsley and a sprinkle of lemon zest to brighten the deep flavors.
