Ingredients for Slow Cooker Sweet and Sour Chicken

I have made this recipe more times than I can count, and these are the exact ingredients I reach for every single time. Using the right balance here makes the difference between a sauce that truly sings and one that falls flat.

• 1½ lbs chicken breasts (cut into uniform, bite-size pieces)
• 1 medium onion (peeled and cut into large pieces)
• ½ cup ketchup I always use a quality ketchup here since it forms the backbone of the sauce
• 3 tbsp soy sauce
• 2 cloves garlic (minced, or 2 tsp minced garlic from a jar)
• ½ tsp ground ginger Pro tip: freshly grated ginger gives a brighter flavor if you have it on hand
• ½ cup honey
• ½ cup white wine vinegar In my experience, do not swap this for plain white vinegar, the flavor difference is very noticeable
• 3 tbsp cornstarch
• ¼ cup cold water Must be cold for a lump-free slurry
• 1 red bell pepper (cut into large pieces)
• 1 green bell pepper (cut into large pieces)
• 1 yellow bell pepper (cut into large pieces)
• 15 oz pineapple chunks in juice (reserve the juice for the sauce, do not drain it)

Step-by-Step Instructions

I recommend reading through all the steps once before you begin. This recipe is genuinely easy from start to finish, and knowing the full flow makes the process feel completely stress-free.

Step 1: Add the chicken pieces and onion directly into your slow cooker. Pour in the ketchup, soy sauce, minced garlic, ground ginger, honey, white wine vinegar, and the juice from the pineapple can. Give everything a quick stir to combine.

Step 2: Place the lid on and cook on low for 6 to 8 hours, or on high for 3 to 4 hours, until the chicken is fully cooked through and tender. Avoid lifting the lid during cooking as this releases heat and extends the cook time.

Step 3: About 40 minutes before serving, whisk together the cornstarch and cold water in a small bowl until completely smooth with no lumps. This step is critical, never add dry cornstarch directly into the slow cooker or it will clump.

Step 4: Stir the cornstarch slurry into the slow cooker along with the bell peppers and pineapple chunks. Cover and cook on high for 30 to 40 minutes until the sauce has thickened and the peppers are just tender but still have a slight bite. If the sauce is still too thin after 40 minutes, whisk an extra tablespoon of cornstarch into a tablespoon of cold water and stir it in, then cook for another 10 minutes.

Step 5: Serve warm over rice and top with sliced green onions and sesame seeds.

What to Serve with Slow Cooker Sweet and Sour Chicken

The bold tangy-sweet flavors of this dish pair best with sides that are neutral, slightly savory, or lightly textured. Here are my favorite combinations.

Steamed White Rice: The classic choice and the one my family reaches for every time. Fluffy white rice soaks up every drop of that glossy sauce and turns this into a complete, satisfying meal. For a protein-packed rice bowl twist, take a look at this Sweet Chili Chicken Bowl with Coconut Lime Drizzle for flavor inspiration.

Brown Rice: A heartier, nuttier option that adds extra fiber and holds up beautifully to the saucy chicken. It is a great way to add a little more nutrition without changing the flavor of the dish at all.

Garlic Fried Rice: For something more indulgent, serve this over a simple garlic fried rice for a full takeout-style dinner at home. This High Protein Crispy Garlic Chicken Fried Rice is a great base for ideas.

Zucchini Noodles: A light, low-carb swap that still delivers satisfying texture. If you enjoy zucchini-based dishes alongside chicken, this Chicken Zucchini Bake pairs beautifully as a complementary side.

Asian Slaw: A crunchy, refreshing contrast to the warm, saucy chicken. This Asian Slaw is one of my go-to sides when I want something cool and crisp alongside a slow cooker meal.

Beef Stir Fry Vegetables: If you want to bulk up the vegetable side of the meal, a simple stir-fried vegetable mix works really well here. This Beef Stir Fry with Fresh Vegetables has great technique tips for getting vegetables perfectly cooked.

Chicken and Rice Meal Prep Bowls: Turning this into a weekly meal prep? These Chicken and Rice Meal Prep Bowls offer a great system for portioning and storing your meals efficiently through the week.

Storage & Serving Tips

Store any leftovers in an airtight container in the refrigerator for up to 5 days. The sauce actually deepens and improves overnight, making this one of those rare dishes that tastes even better the next day. I recommend storing the chicken and sauce separately from the rice to keep the texture from getting mushy.

To reheat, warm the chicken gently in the microwave or on the stovetop over medium-low heat until fully heated through. Pro tip: add a small splash of water or chicken broth when reheating if the sauce has thickened too much in the fridge.

This dish also freezes well. Let it cool completely before transferring to freezer-safe containers. Freeze for up to 3 months and thaw overnight in the refrigerator before reheating. For an easy weeknight meal later in the month, this slow cooker sweet and sour chicken is one of the best make-ahead options in my kitchen. You might also enjoy this Crockpot Creamy Chicken and Noodles as another great slow cooker freezer-friendly option to have in your rotation.
