Before you start

Before starting, ensure your slow cooker insert is clean and dry. Pat the pork loin roast completely dry with paper towels to help the sweet glaze adhere better to the surface of the meat.

Measure out your pineapple chunks and your prepared sweet glaze so everything is ready to be assembled quickly in the slow cooker. Having these simple ingredients prepped and within reach ensures a smooth and efficient assembly process before you turn on the machine.

Ingredients at a glance (3)
  • 3 lb boneless pork loin roast
  • 20 oz pineapple chunks
  • 1 cup sweet glaze, store-bought or made ahead

Instructions

Prep and Assemble

  1. Arrange the Meat and Fruit
    Place the boneless pork loin roast into the center of the slow cooker insert. Arrange the pineapple chunks evenly around the sides of the meat.
    Look for The pork roast should sit flat in the slow cooker with the pineapple chunks surrounding it.
    Tip Ensure the pork loin fat cap is facing upward to help baste the meat as it cooks.

The pork loin sits snugly in the center of the slow cooker insert, surrounded by a vibrant ring of golden pineapple chunks. The raw meat is prepped and ready to absorb the rich flavors of the glaze. The ingredients are neatly arranged, and the sweet glaze is poured evenly over the top, coating the entire surface of the roast before the cooking process begins.

Slow Cooking

  1. Pour the Glaze
    Pour the sweet glaze evenly over the pork loin and pineapple chunks in the slow cooker.
    Look for The glaze should coat the top of the pork and pool at the bottom of the slow cooker.
    Tip Pour slowly to ensure the entire surface of the meat is covered with a thin layer of glaze.
  2. Slow Cook and Rest
    Cover the slow cooker with its lid. Cook on the low setting for 4 to 5 hours. Verify that the pork loin is fully cooked by checking that it reaches an internal temperature of 145°F (63°C) on a meat thermometer. Transfer the pork to a clean cutting board, cover it loosely with foil, and let the meat rest for at least 3 minutes to lock in the juices.
    Look for The pork loin should be tender, and a thermometer inserted into the thickest part must read 145°F (63°C).
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Avoid opening the slow cooker lid during cooking, as this releases valuable steam and heat.

The slow cooker emits a warm, sweet aroma of caramelized sugars and pineapple. The pork loin is tender, and the internal temperature reads 145°F (63°C). The meat is resting under foil, keeping all its savory juices locked inside. The glaze has bubbled and combined with the natural juices of the meat and fruit, creating a rich, flavorful liquid at the bottom of the pot.

Slice and Serve

  1. Slice and Serve
    Slice the rested pork loin into thick, tender slices using a sharp carving knife. Arrange the slices on a serving platter, border them with the warm pineapple chunks, and spoon the warm, sticky glaze from the slow cooker generously over the meat before serving.
    Look for The pork slices should look moist, glistening under a thick layer of the sweet glaze.
    Tip Use a very sharp knife to get clean slices without tearing the tender pork meat.

The sliced pork loin is glistening, perfectly coated in the warm, sticky glaze and surrounded by the tender pineapple chunks. The meat is beautifully arranged on a serving platter, ready to be enjoyed.

Each slice is moist and tender, showing a perfect glaze on the outside and a juicy interior that promises a delicious combination of sweet and savory flavors in every bite.

Common mistakes

The most common mistake is cooking the pork loin on the high setting for too long. Pork loin is a lean cut of meat, and high heat can quickly cause it to become dry and rubbery. Always opt for the low setting on your slow cooker for a gentler cook.

Additionally, do not skip the resting period; slicing the pork immediately after cooking will cause all the flavorful juices to run out onto the cutting board. Another mistake is lifting the lid frequently, which releases heat and extends the cooking time.

How to tell it’s done

The pork loin is perfectly done when a digital meat thermometer inserted into the thickest part of the roast registers 145°F (63°C). At this temperature, the meat remains juicy, tender, and slightly pink in the center.

After reaching this temperature, transfer the roast to a cutting board and let it rest for at least 3 minutes before slicing to allow the juices to redistribute. If you slice the meat too soon, all the delicious juices will run out onto the board, leaving the pork dry.

  • Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
