How to Make Slow Cooker Sweet and Sour Chicken Recipe

Step 1: Coat and Brown the Chicken

Start by placing half of the chicken thighs in a large zippered plastic bag. Sprinkle with 2 tablespoons of cornstarch, seal the bag, and shake to coat the chicken evenly. Next, heat 1 tablespoon of vegetable oil in a large nonstick skillet over medium-high heat. Add the coated chicken and cook for about 3 minutes per side until each piece develops a delightful lightly browned crust. This browning step not only adds beautiful color but enhances flavor by locking in the juices. Transfer this first batch to your slow cooker. Repeat the same process with the remaining chicken, cornstarch, and vegetable oil—your slow cooker will soon be full of golden goodness.

Step 2: Prepare the Sweet and Sour Sauce

Drain the pineapple chunks, reserving the juice for extra flavor in the sauce. In a medium bowl, combine the finely chopped onion, rice vinegar, ¼ cup of the reserved pineapple juice, ketchup, honey, soy sauce or tamari, grated ginger, minced garlic, and salt. Whisk until smooth and aromatic. Pour this vibrant sauce mixture over the browned chicken in the slow cooker, making sure every piece is well-coated. This sauce is the heart of your dish, marrying sweet, sour, salty, and savory notes harmoniously.

Step 3: Slow Cook the Chicken

Cover your slow cooker and set it to HIGH for 3 hours or LOW for 6 hours, depending on your schedule and time. Cooking on low longer will yield extra tender chicken, but either way, you’re in for juicy, flavorful results. During this time, the chicken soaks up the sauce flavors and breaks down into a mouthwatering texture.

Step 4: Add Bell Peppers and Pineapple Chunks

After the chicken has cooked tender, stir in the chopped bell peppers and spoon the reserved pineapple chunks over the top. These additions provide a delightful pop of fresh crunch and juicy sweetness that contrast beautifully with the cooked chicken. Cover again and cook on HIGH for another 30 minutes until the bell peppers soften just enough to be fork tender but still maintain a pleasant bite.

FAQs

Can I use chicken breasts instead of thighs?

Yes, you can substitute chicken breasts; however, thighs tend to stay juicier and more tender during slow cooking. If using breasts, keep an eye on cooking time to avoid drying them out.

Is this recipe gluten free?

Absolutely! Using tamari instead of regular soy sauce makes the sauce gluten free without sacrificing flavor.

Can I skip browning the chicken before slow cooking?

While browning adds flavor and color, it’s optional. You can skip this step for a quicker prep, though the finished dish will have a slightly different texture and depth.

How spicy is this sweet and sour chicken?

This recipe is mild with a balance of sweet and tangy flavors. You can easily add chili flakes or a dash of hot sauce if you like a bit of heat.

Can I prepare this in an Instant Pot instead of a slow cooker?

Yes, you can! Use the sauté function to brown the chicken, then pressure cook on high for about 10 minutes and finish by adding the peppers and pineapple for a few minutes on the sauté setting.
