Ingredients

Why this recipe works

The slow cooker environment is ideal for lean cuts like pork tenderloin because the low, moist heat prevents the meat from drying out.

As the pork cooks, it releases juices that mingle with the pineapple juice and teriyaki sauce, creating a complex, savory-sweet braising liquid that seasons the meat deeply throughout the entire cooking cycle.

Additionally, this method allows the bell peppers to soften and absorb the teriyaki glaze, turning them into a sweet, tender accompaniment that pairs perfectly with the pork.

The slow-cooking process also allows the sugars in the pineapple juice and teriyaki sauce to concentrate, resulting in a naturally glossy, sticky finish that coats the meat beautifully once sliced.

Notes and substitutions

Select high-quality pork tenderloin for the best results, as this cut is naturally lean and benefits from the gentle cooking method.

If the tenderloins vary significantly in size, tuck the thinner ends under to create a uniform thickness, which ensures that the entire piece of meat reaches the safe internal temperature at the same time.

When choosing a slow cooker, ensure it is the appropriate size for the amount of meat being prepared. If the cooker is too large, the sauce may evaporate too quickly; if it is too full, it may not cook evenly. Always use a digital meat thermometer to confirm the pork has reached 145°F (63°C) before removing it from the heat.

• pineapple juice: orange juice provides a similar citrus sweetness that balances the saltiness of the teriyaki sauce.
• teriyaki sauce: a mixture of soy sauce, ginger, garlic, and brown sugar can be used as a homemade alternative.
