How to Make Pernil al Horno

Step 1: Prepare the Pork

Pat the pork shoulder dry with paper towels.

Using a sharp knife, score the skin in a crosshatch pattern without cutting deeply into the meat.

Make several small slits throughout the meat so the marinade can penetrate more deeply.

Step 2: Prepare the Marinade

In a bowl, combine:

• Garlic
• Olive oil
• Lime juice
• Orange juice
• Apple cider vinegar
• Oregano
• Cumin
• Smoked paprika
• Salt
• Black pepper
• Crushed red pepper flakes (if using)
• Thyme or rosemary (optional)

Mix until well combined.

Step 3: Marinate

Rub the marinade generously over the entire pork shoulder, working it into the slits and under any loose areas of the skin whenever possible.

Cover tightly and refrigerate for at least 8 hours, preferably overnight, for maximum flavor.

Step 4: Roast the Pork

Remove the pork from the refrigerator about 30–45 minutes before roasting to allow it to come closer to room temperature.

Preheat the oven to 325°F (163°C).

Place the pork shoulder skin-side up in a roasting pan.

Cover loosely with aluminum foil.

Roast for approximately 35–40 minutes per pound, or until the meat becomes tender and reaches an internal temperature of 195–205°F (90–96°C) for pull-apart texture.

Step 5: Crisp the Skin

Remove the foil during the final 30–40 minutes of cooking.

Increase the oven temperature to 450°F (230°C) and roast until the skin becomes deeply golden and crisp.

Watch carefully to prevent burning.

Step 6: Rest and Serve

Transfer the roast to a cutting board.

Allow it to rest for 20–30 minutes before slicing or shredding.

Serve with the crispy skin alongside the juicy pork.

For exceptional results:
