• ¼ cup cornstarch – Essential for thickening the sauce to that perfect glossy, sticky consistency.
• ½ cup apple cider vinegar – Provides the crucial tangy note that defines classic sweet and sour.
• 1 tbsp minced garlic – Adds an aromatic depth that complements the sweetness and acidity. Freshly minced is always best!
• ⅓ cup ketchup – Contributes to the vibrant color and a foundational sweet-savory base for the sauce.
• 2 tbsp low sodium soy sauce – For umami depth without excessive saltiness. Adjust to taste if using regular soy sauce.
• ½ cup brown sugar – Balances the tartness of the vinegar and ketchup, creating the “sweet” in sweet and sour.
• 1 ½ lbs chicken breast, cubed into bite-sized pieces for even cooking. Chicken thighs can also be used for richer flavor.
• 1 red bell pepper, cubed for color and a sweet, mild crunch.
• 1 green bell pepper, cubed, offering a slightly more bitter contrast and vibrant green.
• 1 yellow onion, cubed, for a foundational sweetness that mellows beautifully during slow cooking.
• 1-2 cups Cooked white rice , (for serving at the end – Jasmine or Basmati work wonderfully)
• 10 oz canned pineapple chunks , (remember to reserve ½ cup of the juice for the sauce!)

1. Prepare the Irresistible Sweet and Sour Sauce: Begin by creating the heart of this dish – the flavorful sauce. In a small mixing bowl, combine the cornstarch and apple cider vinegar. Whisk these two ingredients thoroughly until the cornstarch is completely dissolved and no lumps remain. This cornstarch slurry is crucial for thickening the sauce later. Next, add in the minced garlic, ketchup, low sodium soy sauce, brown sugar, and the reserved ½ cup of pineapple juice. Whisk everything together until the sauce is smooth and all ingredients are well incorporated. Take a moment to savor the aroma; this is where the magic begins!
2. Combine and Cook in the Slow Cooker: Pour the freshly prepared sweet and sour sauce directly into your slow cooker. Add the cubed chicken breast, red and green bell peppers, and the cubed yellow onion. Stir all the ingredients together gently, ensuring that the chicken and vegetables are evenly coated with the luscious sauce. This ensures every piece absorbs the delicious flavors as it cooks. Cover your slow cooker and set it to cook on LOW for 4-5 hours, or on HIGH for approximately 3 hours. Cook until the chicken is tender, thoroughly cooked through, and easily shredded with a fork. The vegetables should be tender-crisp, not overly soft, retaining a pleasant texture.
3. Add Pineapple and Serve: About 15-20 minutes before serving, gently stir in the canned pineapple chunks (drained, after reserving the juice). The pineapple will warm through and infuse the dish with its tropical sweetness without breaking down too much. We highly recommend serving this delightful sweet and sour chicken generously over a bed of fluffy cooked white rice. Don’t forget to spoon plenty of the rich, sticky sauce over the top – it’s truly the best part! For an extra touch of freshness and color, consider garnishing with a sprinkle of chopped green onions or sesame seeds.
