Before you start

Before you begin, ensure your workspace is clean and you have all your ingredients measured and ready to go. Dice the green bell pepper and onion into uniform pieces so they cook evenly in the base of the slow cooker.

If you are using a pre-marinated mojo pork loin, check the packaging to confirm it does not require additional seasoning. If the pork is not pre-marinated, rub it thoroughly with a blend of garlic, cumin, oregano, and citrus zest before placing it in the cooker. Having everything prepped makes the assembly process fast and seamless.

Ingredients at a glance (8)
  • 2 cans black beans, rinsed
  • 1 green bell pepper, diced
  • 1 onion, diced
  • 3.5 lb mojo-spiced pork loin
  • 1 cup orange-lime garlic juice
  • 1/2 cup broth
  • 2 cups saffron yellow rice, for serving
  • 2 lime wedges, for serving

Instructions

Layering the base

  1. Assemble the base
    Place the rinsed black beans, diced green bell pepper, and diced onion into the bottom of the slow cooker ceramic insert. Stir these ingredients briefly to ensure they are evenly distributed, creating a flavorful foundation for the pork loin.
    Look for The vegetables and beans should form an even layer covering the bottom of the pot.
    Tip Rinsing the black beans removes excess starch and sodium, leading to a cleaner flavor.

At the end of this phase, the bottom of your slow cooker should be covered with a vibrant mixture of black beans, diced bell peppers, and onions. The colors should be bright and the ingredients should be evenly distributed across the surface, providing a stable foundation that will support the pork loin and prevent it from sticking to the ceramic insert during the long cooking process.

Adding the protein

  1. Add pork and liquids
    Place the mojo-spiced pork loin directly on top of the bean and vegetable mixture. Pour the orange-lime garlic juice and broth evenly over the pork to ensure the meat stays moist and absorbs the citrus aromatics during the cooking process.
    Look for The liquid should partially submerge the beans while the pork sits elevated on the vegetable bed.
    Tip If the pork loin is very long, feel free to cut it in half to fit comfortably in the slow cooker.

Once the pork loin and liquids are added, the slow cooker should look full but not crowded. The citrus-garlic juice should begin to settle into the bean mixture, creating a fragrant aroma immediately. Check that the pork loin is resting securely on top of the vegetables. The liquid should not be overflowing, and the lid should fit snugly to ensure proper steam retention for the upcoming slow-cooker cycle.

Slow simmering

  1. Slow cook and serve
    Cover the slow cooker and cook on the low setting for 6 hours. Once the time is up, use a meat thermometer to ensure the pork has reached an internal temperature of at least 145°F (63°C). Allow the pork to rest for 5 minutes before slicing it into thick pieces and serving over saffron yellow rice with lime wedges.
    Look for The pork should be tender enough to slice effortlessly and the beans should be thick and stew-like.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Letting the meat rest ensures the juices redistribute throughout the loin, keeping every slice succulent.

After six hours, the kitchen should be filled with the deep, savory scent of garlic and citrus. The pork should appear opaque and tender, showing signs of slight shredding when poked with a fork.

The black beans should have absorbed most of the liquid, transforming into a thick, glossy stew that is ready to be plated. Ensure the meat is fully cooked through and the juices have thickened appropriately before serving.

Common mistakes

A common mistake is lifting the slow cooker lid too frequently, which allows heat to escape and significantly increases the total cooking time. Keep the lid closed for the duration of the six hours to maintain a consistent environment.

Another potential issue is using too much liquid; the pork and vegetables will release their own juices, so avoid adding extra water or broth beyond the amount specified, as this can result in a watery bean mixture rather than a rich, concentrated stew.

How to tell it’s done

The pork loin is perfectly done when it is tender enough to slice without resistance and reaches an internal temperature of at least 145°F (63°C). Using a reliable digital meat thermometer is the best way to confirm safety and quality.

The beans should have thickened into a rich, stewed consistency, and the vegetables should be completely soft. If the pork seems firm, cook for an additional 30 minutes, as slow-cooker temperatures can vary slightly between different models and ceramic pot thicknesses.
