How to Use a Caja China: Cuban Lechón Recipe with Mojo (Video)
Few dishes are more iconic to Cuban culture than lechón asado. Whether it's Christmas Eve, Noche Buena, a family reunion, or a backyard celebration, a whole roasted pig cooked in a Caja China has become a tradition for generations of Cuban families.
If you've never used a Caja China before, don't worry. It's one of the easiest ways to cook a whole pig or large cuts of pork while achieving juicy meat and crispy skin. In this guide and video, we'll walk you through the basics and show you how we use Mucho Mojo™ Cuban Garlic Citrus Marinade & Dip to bring authentic Cuban flavor to every bite.
What Is a Caja China?
A Caja China, or "Chinese Box," is a roasting box commonly used throughout Cuba, Miami, and Latin America to cook whole pigs and large cuts of meat. The design is simple: the meat cooks inside an enclosed box while charcoal burns on a tray above it.
This method creates incredibly even heat, allowing the meat to stay moist while developing the crispy skin that Cuban lechón is famous for.
Today, Caja Chinas are used for everything from whole hogs and pork shoulders to chicken, turkey, and brisket.

How to Marinate Pork for a Caja China
The secret to great Cuban lechón is mojo.
Traditionally, Cuban mojo combines garlic, citrus juice, olive oil, oregano, cumin, and spices. The marinade is injected deep into the meat and allowed to work overnight, creating the bold flavor that makes Cuban roast pork so memorable.
Mucho Mojo™ makes this process easy by combining those traditional flavors into a ready-to-use marinade.
Generously season your pork with salt and inject or rub Mucho Mojo throughout the meat. For best results, refrigerate overnight and allow the flavors to fully penetrate the pork.
If you're short on time, even a few hours will add plenty of flavor. Plus, we actually love having a side of mojo for dipping for even more flavor!
Step-by-Step Caja China Tutorial
Step 1: Prepare the Pork
Remove the pork from the refrigerator about an hour before cooking.
Pat the skin dry and season lightly with salt. Dry skin is one of the keys to achieving crispy crackling later in the cook.
Step 2: Set Up the Caja China
Place the pork inside the roasting rack according to the manufacturer's instructions.
Secure the rack and place it inside the Caja China.
Step 3: Start the Fire
Fill the charcoal tray with the recommended amount of charcoal on your Caja China.
Most Caja China cooks follow a schedule where charcoal is added periodically throughout the cook to maintain consistent heat.
Step 4: Cook Low and Slow
Allow the pork to roast until it reaches the proper internal temperature.
Avoid opening the box unnecessarily, as this releases heat and extends cooking time.
Step 5: Crisp the Skin
Once the meat is nearly finished cooking, flip the pig and focus on crisping the skin.
This is the moment everyone waits for.
Properly cooked lechón should have crispy golden skin that crackles when sliced.
Step 6: Rest and Serve
Remove the pork and allow it to rest for about 45 minutes before carving.
Serve with additional Mucho Mojo drizzled over the meat for an extra burst of garlic-citrus flavor.
How Long Does It Take to Cook a Pig in a Caja China?
Cooking times vary based on the size of the pig and weather conditions.
As a general guideline:
- Small pig (40–60 lbs): 4-5 hours
- Medium pig (60–90 lbs): 5-6hours
- Large pig (90–120 lbs): 6–8 hours
Always cook to internal temperature rather than relying solely on time.
For pork, aim for an internal temperature of at least 195–203°F in the shoulder area for tender, pull-apart meat.
Tips for Crispy Cuban Lechón
If there's one thing Cuban families debate more than politics, it's how to get the perfect cuero.
Here are a few tips:
- Dry the skin thoroughly before cooking.
- Salt the skin generously.
- Avoid excess moisture on the surface.
- Follow your charcoal schedule carefully.
- Give the skin dedicated time to crisp at the end of the cook.
The combination of juicy pork, crispy skin, and mojo is what makes lechón one of Cuba's most beloved dishes.
