📝 About This Recipe

Pernil is the undisputed crown jewel of Puerto Rican holiday feasts, celebrated for its succulent, fall-apart meat and its legendary 'cuerito'—the shatteringly crisp, golden skin. This recipe centers on a deep, garlic-heavy marinade known as 'mojito' that permeates the pork over 24 hours, ensuring every bite is infused with citrus and spice. Slow-roasted to perfection, it fills your home with an aroma that defines Caribbean comfort and hospitality.

🥗 Ingredients

The Pork

  • 8-10 pounds Bone-in Pork Shoulder (Picnic Cut) (skin-on is essential for the cuerito)
  • 2 tablespoons Lime juice (to clean the meat)

The Adobo Mojito (Marinade)

  • 15-20 pieces Garlic cloves (peeled and crushed)
  • 2 tablespoons Dried Oregano (preferably Puerto Rican or Mexican oregano)
  • 1 tablespoon Black Peppercorns (freshly cracked)
  • 3 tablespoons Kosher Salt (adjust slightly based on pork weight)
  • 1/4 cup Olive Oil (extra virgin)
  • 2 tablespoons White Vinegar (helps tenderize the meat)
  • 2 packets Sazón with Culantro y Achote (for color and depth)
  • 1 tablespoon Adobo Seasoning (all-purpose dry seasoning)

👨‍🍳 Instructions

  1. 1

    Rinse the pork shoulder with cold water and lime juice, then pat it thoroughly dry with paper towels. A dry surface is key for the skin's texture later.

  2. 2

    Using a sharp knife, carefully lift the layer of skin and fat away from the meat, leaving it attached at one side like a 'flap' or 'blanket.' Do not remove it completely.

  3. 3

    Using a small paring knife, poke deep 1-inch wide slits all over the meat (under the skin flap) and on the bottom of the roast. These are 'pockets' for your marinade.

  4. 4

    In a mortar and pestle (pilon), mash the garlic cloves, salt, peppercorns, and oregano into a thick paste. Stir in the olive oil, vinegar, Sazón, and Adobo seasoning until well combined.

  5. 5

    Rub the marinade generously into the deep slits you poked earlier. Ensure the meat under the skin flap is well-coated, but do NOT put the marinade on top of the skin itself (salt on the skin is fine, but garlic will burn).

  6. 6

    Lay the skin flap back over the meat and rub the skin only with a light coating of salt and a touch of oil. This helps it crisp up without burning the spices.

  7. 7

    Place the pork in a large roasting pan, cover tightly with plastic wrap, and refrigerate for at least 24 hours. This patience is what separates good pernil from great pernil.

  8. 8

    Remove the pork from the refrigerator 1 hour before cooking to bring it to room temperature. Preheat your oven to 300°F (150°C).

  9. 9

    Cover the roasting pan tightly with heavy-duty aluminum foil, ensuring no steam escapes. Roast in the center of the oven for about 4 to 5 hours (roughly 35-40 minutes per pound).

  10. 10

    Remove the foil. The meat should be tender. Increase the oven temperature to 400°F (200°C) to crisp the skin.

  11. 11

    Roast uncovered for another 30-45 minutes. Watch closely! You are looking for the skin to bubble and turn into hard, crunchy 'cuerito.' It should sound hollow when tapped with a knife.

  12. 12

    Once the skin is perfect, remove the pan from the oven. Let the meat rest for at least 20-30 minutes before carving. This allows the juices to redistribute.

  13. 13

    Remove the crisp skin entirely and crack it into pieces. Shred or slice the succulent meat underneath, and serve each portion with a piece of the golden cuerito.

💡 Chef's Tips

Never cover the pork with foil during the final high-heat stage, or the skin will turn rubbery instead of crispy. Always use a bone-in shoulder; the bone acts as a heat conductor and adds incredible flavor to the surrounding meat. If the skin isn't crisping evenly, you can carefully use the broiler for 2-3 minutes at the very end, but stay focused—it burns in seconds. Avoid putting citrus juice in the marinade for a long soak, as it can turn the meat mushy; stick to vinegar for the overnight sit. Save the pan drippings! Skim the fat and pour the 'jus' over the shredded meat for extra moisture.

🍽️ Serving Suggestions

Serve with Arroz con Gandules (Rice with Pigeon Peas) for the most authentic Puerto Rican experience. A side of sweet fried plantains (maduros) provides a perfect sugary contrast to the salty pork. Fresh avocado slices and a simple green salad help cut through the richness of the fat. Pair with a cold Medalla beer or a refreshing glass of Parcha (passion fruit juice). Leftovers are legendary when used for 'Cubano' style sandwiches the next day.
