Simple Pernil: Puerto Rican Roast Pork

Crispy edges, garlicky mojo vibes, and fork-tender pork that feeds a crowd. This pernil is approachable, forgiving, and absolutely worth the slow roast. The only catch is giving a big shoulder the time it needs to get truly tender.

Pernil is one of those dishes that makes your kitchen smell like you know what you are doing. It is Puerto Rican style slow-roasted pork shoulder, seasoned boldly with garlic, oregano, citrus, and enough salt to make the whole thing sing. You get the best of both worlds: juicy, shreddable meat inside and crisp, crackly bits outside.

This is the simple pernil recipe I reach for when I want big results without a million moving parts. We keep ingredients accessible, instructions clear, and we lean on time and smart seasoning to do the heavy lifting. If you can stir together a garlicky paste and turn on your oven, you are in business.

Why It Works

  • Deep flavor, not complicated flavor. A simple garlic and herb rub plus citrus hits all the right notes, especially after an overnight rest.
  • Juicy and tender texture. Low and slow roasting gives you sliceable meat that can also be pulled apart with a fork.
  • Crisp edges on demand. A quick blast of high heat at the end creates those browned, crunchy bits everyone fights over.
  • Flexible serving styles. Serve it as a holiday centerpiece, tuck it into sandwiches, or pile it over rice with the pan juices.

Storage Tips

Refrigerate: Cool pernil to room temp (no more than 2 hours), then store in an airtight container for up to 4 days. Pour a little of the pan juices over the meat before sealing. That is your anti-dryness insurance.

Freeze: Freeze shredded or sliced pork in freezer bags or containers for up to 3 months. Add a splash of broth or pan juices before freezing if you have them.

Reheat (best method): Warm in a covered skillet with a few spoonfuls of water, broth, or reserved juices over medium-low until hot. Uncover at the end to crisp edges. You can also reheat in a 325°F oven covered with foil.

Pro tip: If you want that fresh-roast vibe, spread reheated pork on a sheet pan and broil for 2 to 4 minutes to re-crisp the top. Watch it closely.

Common Questions

Do I have to marinate pernil overnight?

You do not have to, but it is the easiest way to level it up. Even 6 hours helps. Overnight gives the garlic and oregano time to mellow and sink in.

What cut of pork is best for pernil?

Pork shoulder is the friendly choice. Look for bone-in if possible for extra flavor and a little moisture insurance. In many stores it is labeled pork shoulder, picnic shoulder, or Boston butt. Any well-marbled shoulder roast works.

How long does a 7 to 9 lb pernil take to cook?

Plan on about 45 to 60 minutes per pound at 325°F when roasting covered, because you are not just “cooking it through,” you are breaking down collagen. For a 7 to 9 lb bone-in shoulder, that is often 5 1/2 to 7 hours, plus the final crisping time and rest. Always cook to tenderness and temperature, not the clock.

How do I get crispy skin or crispy edges?

If your roast has skin, keep it dry, salt it well, and finish with high heat. If there is no skin, you can still get crispy edges by uncovering and roasting at 450°F for the last 15 to 25 minutes, then broiling briefly if needed.

My pernil seems tough. What happened?

It probably just needs more time. Pork shoulder gets tender when collagen breaks down, and that happens closer to 195 to 205°F internal temp. Keep roasting covered until it is fork-tender.

Can I make this in advance?

Yes. Pernil is a make-ahead hero. Roast it a day early, chill with juices, then reheat covered at 325°F until hot and finish with a quick high-heat crisp.

The first time I made pernil, I treated it like any other roast and expected it to be done when the thermometer said “safe.” It was safe, sure. It was also stubborn and chewy. The next time I let it go low and slow until it practically sighed when I poked it, and suddenly I understood the hype. Now it is one of my favorite ways to feed people because it feels a little dramatic when it hits the table, but the work is mostly just patience and tasting the seasoning paste like you are the boss of the kitchen.
