Getting started with this slow cooker sweet and sour chicken is as easy as it gets. Begin by gathering and prepping all your ingredients to keep things smooth and fun. This recipe keeps prep time to just 10 minutes, perfect for a quick start.

Place the chicken, onion, tomato puree, light soy sauce, garlic, ginger, honey, white wine vinegar, salt, pepper, and the juice from the pineapple can into the slow cooker.
Cook on high for 3 hours or low for 5-6 hours. Remember to save the pineapple chunks for later to keep their texture just right.
In a small bowl or mug, mix the cornflour with enough liquid from the slow cooker to make a smooth paste, called a slurry, then pour it back in.

Return to the slow cooker on high for 30 minutes or transfer to the hob and cook for 15 minutes until the sauce thickens and the peppers soften slightly.

FAQs: Frequently Asked Questions About Slow Cooker Sweet And Sour Chicken

How do I thicken the sauce for Slow Cooker Sweet and Sour Chicken without lumps?

To thicken the sauce smoothly, mix cornflour (cornstarch in the US) with a small amount of the cooking liquid from the slow cooker to form a paste before stirring it back into the sauce. This prevents lumps from forming, which can happen if you add cornflour directly to the dish. Allow the sauce to cook for 10–15 minutes after adding the paste to reach the desired thickness.

Can I prepare Sweet and Sour Chicken on the stove instead of a slow cooker?

Yes, Sweet and Sour Chicken can be made on the stovetop. Use the same ingredients and follow similar cooking times, adjusting heat to a gentle simmer to allow flavors to meld without overcooking. Browning the chicken pieces before combining them with the sauce enhances flavor and texture.

What is the best way to brown chicken when using a slow cooker for this recipe?

To brown chicken before slow cooking, use a pan compatible with your heat source. Many slow cooker inserts work on gas or electric stovetops, allowing you to sear chicken directly in the slow cooker pot or a separate skillet. Browning seals in juices and adds a richer flavor to the finished dish.

How long should I cook Sweet and Sour Chicken in a slow cooker?

Cook Sweet and Sour Chicken on low for 4 to 6 hours, or on high for 2 to 3 hours. Cooking on low yields tender chicken and well-developed flavors but take care not to overcook, as the chicken can become dry or stringy.

Can I add vegetables to the Slow Cooker Sweet and Sour Chicken? Which ones work best?

Yes, adding vegetables is a great way to increase nutrition and flavor. Bell peppers, pineapple chunks, onions, and carrots work well. Add firmer vegetables like carrots at the start of cooking and more delicate ones, such as bell peppers, during the last hour to avoid over-softening.
