Cuban Pork Loin Recipe: Moist Oven-Roasted with Celery Salt Crunch

This Cuban pork loin recipe delivers perfectly moist, tender meat with a signature celery salt crunch that makes every bite unforgettable. 🌟 After years of testing oven techniques, I've perfected a method that keeps the pork juicy while creating that crispy exterior—no dry slices here.

The secret lies in slow-roasting with citrus and garlic, then finishing with a celery salt crust that adds texture without overpowering the natural flavors.

What sets this recipe apart is the balance of Cuban flavors—bright citrus, aromatic garlic, and the signature celery salt topping. I use a simple marinade of orange juice, garlic, and spices that infuses the meat while keeping prep straightforward.

The oven method ensures even cooking, with foil tenting that locks in moisture as the pork roasts to perfection.

By the time you serve this dish, you'll have a centerpiece that's tender on the inside, crisp on the outside, and bursting with Cuban-inspired flavors. The pork practically falls apart when sliced, making it ideal for sandwiches, tacos, or serving alongside black beans and rice.

This is restaurant-quality comfort food that belongs in your home kitchen.

Whether you're cooking for a family dinner or meal prepping for the week, this recipe delivers consistent results. The method is foolproof, and the flavors are undeniably satisfying—exactly what you'd find in a Cuban home kitchen. Let's get started on creating this showstopper.

Ingredients for cuban pork loin recipe oven

Six ingredients plus a few pantry staples—this is your Cuban pork loin shortcut.

The pork loin is non-negotiable here. Center-cut is key—it stays juicy while roasting. Grab one from the butcher counter at Whole Foods or your local market if you can, but the regular supermarket cut works too. Look for a piece that's about 1.5 inches thick—thinner slices dry out faster. I always ask for bone-in (the flavor!), but boneless works if that's all you've got. For the celery salt, Lawry's is the gold standard, but any brand with real celery flavor will do—skip the pre-mixed stuff with anti-caking agents.

No fresh orange juice? Bottled works in a pinch, but the real stuff makes all the difference. The garlic can be roasted whole in the marinade (peel after toasting) for a sweeter flavor. Running low on olive oil? Avocado oil is a great swap—same high smoke point. For the celery salt crust, don't skip the lemon juice at the end—it cuts through the richness and makes the celery salt sing. Fresh parsley is ideal, but dried parsley at one-third the amount gets you close if you're in a bind. Pro tip: toast your cumin seeds in a dry pan for 30 seconds before grinding for maximum flavor.

Marinate the pork for at least 2 hours—overnight is even better. The roasted garlic marinade keeps for 3 days in the fridge, so make extra for sandwiches. After roasting, the pork stays juicy for 3 days wrapped tightly in foil. For meal prep, slice and store in portions—it reheats beautifully. The celery salt crust gets soggy if stored, so add it fresh before serving. Leftovers? Shred and toss with black beans and rice for a Cuban-inspired bowl.

Step-by-step instructions for Cuban pork loin

Here's how to make juicy, flavor-packed Cuban pork loin with a crispy celery salt crust.

In a large bowl, combine the 1 cup fresh orange juice, 6 cloves minced garlic, 0.25 cup olive oil, 1.5 tsp salt, 0.5 tsp ground black pepper, 1 tsp dried oregano, and 0.5 tsp ground cumin. Whisk until everything is well mixed and the oil is emulsified—this creates a flavor-packed marinade that tenderizes the meat.

Place the 3 lb bone-in pork loin in a resealable plastic bag and pour the marinade over it. Seal the bag and massage the marinade into the meat, making sure it coats all sides evenly. Let it marinate in the refrigerator for at least 4 hours (overnight is even better). This step is crucial for keeping the pork moist and infusing it with those bright citrus and spice flavors.

Preheat your oven to 350°F. Remove the pork from the marinade (reserve the marinade for later) and pat it dry with paper towels—this helps create that crispy celery salt crust. Place the pork on a rack set inside a roasting pan to allow air to circulate around it.

In a small bowl, mix together the 0.5 cup celery salt with 1 tbsp fresh lemon juice. This creates a dry rub that will give your pork that signature Cuban crunch. Rub this mixture all over the pork, pressing it into the surface so it sticks well. Let the pork sit at room temperature for 30 minutes before roasting—this ensures even cooking.

Roast the pork in the preheated oven for 1 hour and 15 minutes (or until the internal temperature reaches 145°F when measured with a meat thermometer). The celery salt crust should be golden brown and crispy, and the pork should be juicy and tender when pierced with a knife.

Here's the thing—don't open the oven door during cooking. Every time you peek, you lose heat and moisture. Instead, trust your cooking time and thermometer. If you're worried, use an oven thermometer to ensure your oven is actually at 350°F—many ovens run hot or cold.

Once the pork reaches 145°F, remove it from the oven and transfer it to a cutting board. Let it rest for 15-20 minutes before slicing. This resting period is what keeps the pork moist and juicy—it allows the juices to redistribute throughout the meat instead of running out when you cut into it.

Use a sharp carving knife to slice the pork into ½-inch thick slices. Garnish each slice with 0.25 cup chopped fresh parsley for a pop of color and freshness. Serve the pork with the reserved marinade (simmered for 5 minutes to thicken) drizzled over the top for extra flavor.

Storing and reheating your leftovers

Refrigerator Storage

Your cooked Cuban pork loin stays fresh and juicy in the refrigerator for up to 3 days when stored properly. Let it cool completely before wrapping tightly in heavy-duty aluminum foil—this preserves moisture better than plastic.

I like to portion it into ½-inch thick slices and store them in an airtight container with a splash of reserved marinade at the bottom. This keeps the meat from drying out and adds extra flavor when reheating. 🥩

Freezer Prep Tips

For longer storage, freeze the pork in 1-2 day portions using freezer-safe containers or heavy-duty freezer bags. Lay slices flat between parchment paper to prevent sticking, then seal tightly, squeezing out excess air. Label with the date—it keeps quality for up to 3 months.

The celery salt crust gets soggy when frozen, so save that for fresh serving. Thaw overnight in the fridge for best texture.

Reheating Methods

My go-to method is the stovetop: place slices in a skillet over medium-low heat with 1 tbsp reserved marinade per serving. Cover and heat for 5-7 minutes, stirring occasionally, until warmed through.

For microwave reheating, cover slices with a damp paper towel and heat on 50% power for 1-2 minutes, then check—this prevents drying.

Oven Refresh

For a restaurant-style reheat, preheat oven to 325°F and place pork slices on a baking sheet. Drizzle with marinade, cover loosely with foil, and bake for 10-12 minutes.

The foil traps moisture while the oven gently reheats. This method works perfectly for meal prep—just slice and store portions before cooking.

Crispy Crust Revival

Want that signature celery salt crunch back? After reheating, sprinkle slices with 1 tsp celery salt and ½ tsp lemon juice, then broil for 1-2 minutes until lightly toasted. This quick step restores that satisfying texture without overcooking the meat. Perfect for serving over rice or in sandwiches! 🌟
