Before you start
Before beginning, ensure that your work surface is clean and your knife is sharp to make cubing the pork loin safe and efficient. Prepare all your ingredients by washing the bell peppers thoroughly, removing the seeds and stems, and cutting them into uniform cubes.
Open your pineapple and measure out the sauce so that assembly can happen quickly. Having everything measured and ready to go before you start makes the layering process seamless and prevents any unnecessary delays once the slow cooker is ready to be loaded.
Ingredients at a glance (4)
- 1 lb pork loin, cut into cubes
- 2 cups green bell peppers, chopped
- 1 cup pineapple chunks
- 1 cup sweet and sour sauce
Instructions
Layering the Base
- Prepare the Slow CookerPlace the cubed pork loin into the bottom of the slow cooker basin. Ensure the pieces are spread out in an even layer to promote consistent cooking throughout the process.Look for The pork should cover the bottom of the cooker.Tip Trim any excess fat from the pork loin before cubing to ensure a cleaner flavor.
The pork loin cubes should be arranged in a single layer at the bottom of the slow cooker. This provides a stable foundation for the other ingredients and ensures the meat cooks evenly. Ensure the power cord is clear of any water or heat sources.
Adding Aromatics and Sauce
- Layer the IngredientsScatter the chopped green bell peppers over the pork, then add the pineapple chunks on top. Finally, pour the sweet and sour sauce evenly over the entire mixture to coat the ingredients.Look for All ingredients should be layered and coated with the sauce.Tip Do not stir the ingredients; layering allows the flavors to meld slowly.
The bell peppers, pineapple, and sauce are layered on top of the pork. The sauce should be distributed evenly to ensure that every piece of meat and vegetable is lightly coated. The slow cooker is now ready to be covered and turned on.
Slow Cooking and Resting
- Cook and RestCover the slow cooker and cook on low for 4 to 6 hours or high for 2 to 3 hours. Once the pork reaches an internal temperature of 145°F (63°C), turn off the cooker. Let the pork rest for 5 minutes before serving.Look for The pork is tender and the sauce has thickened slightly.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Check the temperature at the thickest part of the meat.
The pork is cooked until it reaches 145°F (63°C). The kitchen should smell savory and slightly sweet. After turning off the heat, allow the meat to rest for 5 minutes, which allows the sauce to thicken and the flavors to settle before serving.
Common mistakes
A common mistake is overcrowding the slow cooker, which can prevent the sauce from circulating properly and lead to uneven cooking. Always ensure the ingredients are spread out in a single layer if possible.
Another error is cutting the pork into pieces that are too small, which can cause them to become dry or disintegrate during the long cooking time. Aim for uniform one-inch cubes.
Finally, avoid lifting the lid frequently during the cooking process, as this releases heat and moisture, significantly increasing the total cooking time required.
How to tell it’s done
The pork is done when it is tender enough to be easily pierced with a fork and has reached a safe internal temperature of 145°F (63°C). Because the pork loin is a lean cut, it is important not to overcook it, as this can lead to a stringy texture.
Use a digital meat thermometer inserted into the thickest piece of pork to verify the temperature. After reaching this point, allow the meat to rest for at least 3 minutes, which helps the juices redistribute and ensures the meat remains moist.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
