📝 About This Recipe

Pernil is the soul of Puerto Rican celebratory cooking, a labor of love that transforms a humble pork shoulder into a masterpiece of tender meat and shatteringly crisp skin. Marinated in a pungent, garlicky 'mojito' of herbs and spices, the pork slow-roasts for hours until it falls apart at the touch of a fork. The crowning glory is the 'cuerito'—the golden-brown crackling skin that is often the most coveted part of the feast.

🥗 Ingredients

The Roast

  • 8-10 pounds Bone-in Pork Shoulder (Picnic Ham) (skin-on is essential for the crackling)

The Marinade (Adobo Mojito)

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

Aromatics for the Pan

  • 1 large Yellow Onion (thickly sliced)
  • 1 cup Water (to prevent pan drippings from burning)

👨‍🍳 Instructions

  1. 1

    Rinse the pork shoulder under cold water and pat it extremely dry with paper towels. A dry surface is key for the marinade to stick.

  2. 2

    Using a sharp knife, carefully lift the layer of skin and fat from the meat, leaving it attached at one side so you can peel it back like a blanket. Do not remove it completely.

  3. 3

    Using a small paring knife, stab deep 1-inch wide slits all over the meat (under the skin) and on the bottom side of the roast. These 'pockets' will hold the marinade.

  4. 4

    Prepare the marinade: In a mortar and pestle (pilon) or a small food processor, crush the garlic, salt, peppercorns, and oregano into a thick paste. Stir in the olive oil, vinegar, sazón, and adobo.

  5. 5

    Rub the marinade generously into the deep slits you created, then coat the entire surface of the meat. Flip the skin back over the meat and rub only a little oil and salt on top of the skin (keep the garlic paste away from the top of the skin to prevent burning).

  6. 6

    Place the pork in a large roasting pan, cover tightly with plastic wrap, and refrigerate for at least 24 hours. 48 hours is even better for deep flavor penetration.

  7. 7

    Remove the pork from the refrigerator 1 hour before cooking to take the chill off. Preheat your oven to 300°F (150°C).

  8. 8

    Add the sliced onions and 1 cup of water to the bottom of the pan. Cover the roasting pan tightly with heavy-duty aluminum foil, ensuring no steam escapes.

  9. 9

    Roast in the oven for about 5 to 6 hours (roughly 35-40 minutes per pound). The meat should be fork-tender and beginning to pull away from the bone.

  10. 10

    Remove the foil and increase the oven temperature to 425°F (220°C). This is the critical stage for the 'cuerito'.

  11. 11

    Roast uncovered for another 20-35 minutes. Watch it closely! The skin will puff up and become hard and golden brown. Tap it with a spoon; it should sound like knocking on wood.

  12. 12

    Remove the roast from the oven and let it rest for at least 30 minutes before carving. This allows the juices to redistribute so the meat stays moist.

  13. 13

    To serve, remove the crispy skin entirely and crack it into pieces. Shred or slice the meat and serve with the skin pieces on top.

💡 Chef's Tips

Never cover the pork with foil once you start the high-heat browning phase, or the skin will turn rubbery. Always use a bone-in shoulder; the bone provides much more flavor and moisture during the long roast. If the skin isn't crisping evenly, you can use the broiler for the last 2-3 minutes, but stay right there—it burns in seconds. Save the pan drippings! Strain them and pour over the shredded meat for an extra flavor punch. Avoid using a boneless loin; it is too lean and will dry out during the long cooking process.

🍽️ Serving Suggestions

Arroz con Gandules (Rice with Pigeon Peas) is the traditional and essential partner for Pernil. Serve with a side of sweet fried maduros (ripe plantains) to balance the salty, savory pork. A simple green salad with a light lime vinaigrette helps cut through the richness of the fat. Pair with a cold Medalla beer or a refreshing glass of Parchita (passion fruit) juice. Leftovers are legendary when pressed into a 'Cubano' style sandwich the next day.
