Let’s break down what makes this sauce so good…

Ingredients for Slow Cooker Sweet and Sour Chicken

• 1.5 lbs boneless skinless chicken breasts or thighs, cut into 1-inch pieces
• 2 bell peppers (one red, one green), cut into chunks
• 1 small yellow onion, cut into chunks
• 1 cup pineapple chunks (canned in juice, reserve the juice)
• 1/2 cup pineapple juice (from the can)
• 1/4 cup apple cider vinegar
• 1/4 cup ketchup
• 2 tablespoons soy sauce
• 1/4 cup brown sugar, packed
• 2 cloves garlic, minced
• 1 teaspoon fresh ginger, minced
• 2 tablespoons cornstarch
• 2 tablespoons cold water

To make this recipe, you’ll want a 6-quart slow cooker and I also recommend using slow cooker liners for easy cleanup.

How to Make Slow Cooker Sweet and Sour Chicken

Place the chicken pieces, bell peppers, onion, and pineapple chunks into the slow cooker.

In a medium bowl, whisk together the pineapple juice, apple cider vinegar, ketchup, brown sugar, soy sauce, garlic, and ginger until the sugar is dissolved and the sauce is well combined.

Pour the sauce over the ingredients in the slow cooker and stir to ensure everything is evenly coated.

Cover the slow cooker and cook on low for 3 to 4 hours or on high for 1.5 to 2 hours, until the chicken is tender and cooked through.

Now here’s where the sauce transforms…

In a small bowl, whisk the cornstarch and cold water together until smooth to create a slurry.

Stir the slurry into the slow cooker and cook on high for an additional 20 to 30 minutes until the sauce has thickened to your liking.

Serve the chicken and vegetables warm over a bed of white or brown rice.

Slow Cooker Tips

Brown any chicken briefly in a hot skillet for 1–2 minutes per side if you want a deeper flavor and better texture. This step is optional but helps seal juices and adds color.

Use fresh ginger and garlic when you can. They give brighter, cleaner flavor than powdered versions.

Adjust vinegar and sugar to your taste; add a splash more vinegar for tang or a tablespoon more sugar for sweetness.

Don’t overcook veggies. Add bell pepper in the last 60–90 minutes on LOW so it stays slightly crisp.

If the sauce is too thin, make and add a little more cornstarch slurry. Taste once before serving and tweak salt, soy sauce, or pineapple juice.

Serving and Storage Suggestions

Best Dishes to Pair With

Serve the sweet and sour chicken over steamed white rice, jasmine rice, or brown rice for a filling plate. For lower carbs, use cauliflower rice or serve with steamed broccoli and snap peas instead of rice.

Offer pickled cucumber or a simple slaw for contrast. Sprinkle with toasted sesame seeds and chopped green onions for color and crunch.

If you want takeout-style texture, serve with crispy egg rolls or potstickers on the side.

Don’t skip this part if you’re planning for leftovers…

How to Store and Reheat Leftovers

Cool the chicken to room temperature no longer than two hours after cooking, then transfer to airtight containers. Store in the fridge for up to 4 days or freeze for 2–3 months.

When reheating from the fridge, warm a single portion in a microwave-safe bowl for 1–2 minutes, stirring halfway, until the center reaches 165°F (74°C).

On the stove, reheat gently in a skillet over medium-low heat with a splash of water or broth to loosen the sauce.

For frozen portions, thaw overnight in the fridge before reheating.

If reheating from frozen, use a covered skillet over low heat and add 2–3 minutes more than usual; check temperature. Do not refreeze thawed leftovers.

Creative Leftover Ideas

Leftover sweet and sour chicken works well in quick meals later in the week.

Spoon it over fresh rice or noodles, tuck it into wraps, or add it to a simple fried rice with extra vegetables.

The sweet and tangy sauce also pairs well with roasted broccoli or stir-fried cabbage for an easy next-day dinner.

You can prep the sauce and chop vegetables up to 48 hours ahead and store them separately in the fridge. Keep raw chicken in its own container until you’re ready to assemble to avoid cross-contamination.

For a true dump-and-go meal, combine sauce, veggies, and chicken in the slow cooker insert the night before, cover, and refrigerate.

In the morning, bring the insert to room temperature for 30 minutes before starting the cooker to promote even cooking.

If you plan to freeze a full meal, assemble in freezer-safe bags: remove as much air as possible, label with date, and freeze flat. Thaw in the fridge and cook on low for 4–6 hours or until chicken reaches 165°F (74°C).
