For the Sweet and Sour Sauce
- 1/2 cup pineapple juice
- 1/3 cup brown sugar, packed
- 1/4 cup rice vinegar
- 1/4 cup soy sauce
- 1 tablespoon fresh ginger, minced
- 2 cloves garlic, minced

Equipment / Tools Needed

- Chef’s knife
- Cutting board
- Small mixing bowl
- Whisk
- Tongs
Step-by-Step Instructions
Step 1: Prepare the Ingredients
Start by washing and chopping your bell peppers, onion, and chicken breasts into uniform, bite-sized pieces. Aim for pieces that are roughly one inch in size so that they cook evenly and maintain a pleasant texture during the long cook time.
Step 2: Combine in the Slow Cooker
Place the chicken chunks, chopped peppers, onions, and pineapple pieces into the base of your slow cooker. Arrange them so they are evenly distributed, ensuring the chicken is nestled beneath the vegetables to soak up the juices as they cook.
Step 3: Whisk the Sauce
In a separate small mixing bowl, whisk together the pineapple juice, brown sugar, rice vinegar, soy sauce, minced ginger, and minced garlic. Pour this mixture over the contents of the slow cooker, using a spoon to gently coat the chicken and vegetables.
Step 4: Cook the Dish
Cover the slow cooker with its lid and set to low heat for 3 to 4 hours, or until the chicken is cooked through and tender. If you prefer a faster approach, you can set it to high for 2 hours, though low heat remains the best method for maintaining the structural integrity of the chicken.
Step 5: Thicken and Serve
Once the cooking time is complete, stir in the cornstarch slurry. Cover and cook on high for an additional 15 minutes to allow the sauce to bubble and thicken into a glossy, translucent glaze that coats everything perfectly.

Tips & Tricks
To achieve the best texture, avoid overcooking the bell peppers; if you prefer them with a slight crunch, add them to the slow cooker during the last hour of cooking. For an extra punch of flavor, garnish the finished dish with toasted sesame seeds or freshly sliced green onions before serving.
Serving Suggestions
This dish is best served over a bed of fluffy jasmine rice or brown rice to soak up the excess sauce. For a lighter alternative, consider serving it alongside stir-fried snap peas or cauliflower rice. It makes an excellent main course for family gatherings or meal-prepped lunches throughout the week.
Variations / Substitutions
If you prefer a spicier profile, add a teaspoon of chili garlic sauce or red pepper flakes to the sauce mixture. You can also substitute the pineapple chunks with mango slices for a different tropical twist, or use chicken thighs if you prefer a richer, darker meat that stays exceptionally moist during slow cooking.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm the chicken gently in a skillet over low heat, adding a splash of water or extra pineapple juice if the sauce has thickened too much in the fridge. Avoid microwaving for long periods as this can toughen the chicken.
