  • 8 bone in pork shoulder
  • adobo sprinkled all over roast

Mojo Seasoning

  • heads garlic peeled
  • 1 tbsp oregano
  • 2 tbsp white vinegar
  • 2 tbsp vegetable oil
  • 1 tsp cumin
  • ½ tsp crushed red pepper
  • 1 tsp ground pepper

Red Onion Topping (Optional)

  • 2 red onions sliced
  • 1-2 limes or lemons


  • Add all the ingredients to a blender or food chopper for the mojo seasoning until well blended and forms a paste.
  • Rinse the pernil.
    Place in a roasting pan.
  • Score the top of the skin with a knife and also make a few slits underneath skin about an inch and a half deep.
    Make a few more slits all over pork shoulder, top bottom and sides.
  • Using your hands, rub the garlic paste all over pork shoulder including inside all the slits you have made.
  • Sprinkle the whole roast with adobo.
    Cover the roast with aluminum foil and refrigerate overnight.

Cook Pernil

  • Preheat oven to 325 degrees.
  • Take the pernil out of the refrigerator and let it sit on counter for 30 minutes before roasting.
    Add a cup of water to bottom of roasting pan.
  • For each pound of roast, cook pork shoulder covered 35-40 minutes per pound.
    Example: for my 8 pound pernil, I cooked it for 4.5 hours.
  • Increase oven to 450 degrees.
  • In the last 40 minutes of cooking, uncover pork and crisp skin until bubbly. (Keep a close eye on it that it doesn't burn)
  • Once pork is cooked, remove from oven and let it sit for 20 minutes before carving.
    Transfer pork to a cutting board and remove skin.
  • Cut skin into pieces.
    Cut pork and return pieces to roasting pan.
    Let it sit in pan juices to soak up all the flavors.
    (Note: The pork will fall apart and almost resemble shredded pork.

Red Onions (Optional)

  • Slice the red onions and place in a saucepan with juice from one lemon or lime.
  • Cook onions over medium heat until soft but still a little crunchy.
  • Place cooked onions in a bowl and serve beside pork when serving pernil asado.
