I had a house full of sickos this weekend. A pretty serious cold hit our house and it hit hard. I had light symptoms but everyone else was miserable, so what to do? I spent the entire weekend in the kitchen recipe testing and I came up with a couple of delicious dinner ideas that I think you guys are really going to love.

Feed a cold, starve a fever? Well, definitely feed a cold!

Of course, they’re all feeling better today and the darn thing hit me like a truck yesterday. So, this morning I’m snuggled under a blanket watching The Today Show with the pups at my side and thought I’d share the results one of my recipe tests this weekend.

I love trying new things in the slow cooker just to see if I can make it work and this Slow Cooker Sweet and Sour Chicken works spectacularly.

The sticky, sweet sauce is reminiscent of the takeout version and I was so impressed by the texture of the chicken. It cooks just until it is perfectly fork tender but still holds its shape.

The first step is to whip up the sauce which consists of some of the reserved pineapple juice from a can of pineapple chunks, chopped onion, rice vinegar, ketchup, honey, soy sauce, fresh ginger, garlic, and salt.

You’ll save those pineapple chunks from your can of pineapple for the very last step in this recipe.

Ingredient Tip

Store unpeeled fresh ginger root in a small resealable plastic freezer bag in your freezer. Peel and use a microplane zester or cheese grater to grate the frozen ginger root for recipes, when needed. Ginger root will keep well in the freezer for about a month.

I used boneless, skinless chicken thighs for this recipe. They are super economical but also have more flavor than boneless breasts and get SO tender in the slow cooker. They are halved and coated in cornstarch and do a quick turn in a non-stick skillet with just a little oil to get that lightly golden brown texture we are after. The cornstarch also helps to thicken the sauce as it cooks.

Brown the chicken in batches and transfer it to your slow cooker.

Sauce is poured over the top of the chicken in the slow cooker.

Pour the flavorful sauce over the top and cover and cook on HIGH for 3 hours or on LOW for 5 to 6 hours or until the chicken is fork tender but not falling apart.

Colorful bell peppers are added to the slow cooker.

At this point, add some chopped bell peppers. A variety of colors makes this a gorgeous dish.

Chunks of pineapple are added to the slow cooker.

Stir the bell peppers down into the sauce and add the pineapple chunks right over the top. Cover and cook on HIGH for an additional 30 minutes, or until the bell peppers are tender.

It’s during this last cook that you can get your rice started.

With the help of the cornstarch coated chicken, the sauce cooks down to the perfect consistency.

Ingredients 

  • 3 pounds boneless, skinless chicken thighs, trimmed of excess fat and sliced in half
  • 4 tablespoons cornstarch, divided
  • 2 tablespoons vegetable oil, divided
  • 8 ounces pineapple chunks in pineapple juice (not syrup)
  • ½ cup finely chopped white or yellow onion
  • ½ cup rice vinegar
  • ¼ cup ketchup
  • ¼ cup honey
  • 2 tablespoons low sodium soy sauce, or tamari for gluten free
  • 2 teaspoons grated fresh ginger root
  • 2 teaspoons minced garlic
  • ¾ teaspoon salt
  • 2 to 3 bell peppers, assorted colors, seeded and chopped
  • 3 green onions, thinly sliced

Instructions 

  • Place half of the chicken thighs in a large zippered plastic storage bag and sprinkle with 2 tablespoons cornstarch. Seal the bag and shake until chicken is evenly coated.
  • Heat 1 tablespoon of oil in a large nonstick skillet over MEDIUM-HIGH. Add the coated chicken and cook 3 minutes on each side or until lightly browned. Transfer the browned chicken to a 5 to 6 quart slow cooker.
  • Repeat the coating and browning process with the remaining chicken, cornstarch, and oil.
  • Drain and reserve the juice from the can of pineapple chunks. Cover and refrigerate the drained pineapple chunks for later.
  • Combine the finely chopped onion, rice vinegar, ¼ cup of the reserved pineapple juice, ketchup, honey, soy sauce (or tamari), ginger, garlic, and salt in a medium bowl. Pour the sauce over chicken in slow cooker. Cover and cook on HIGH for 3 hours or on LOW for 6 hours, until chicken is tender and cooked through. Stir the chopped bell pepper into the chicken and sauce and spoon the reserved pineapple chunks over the top. Cover and cook on HIGH for an additional 30 minutes, or until the bell pepper is fork tender.
  • Serve over rice garnished with green onions.

  1. Karen says:

    5 stars
    Amazing! Everyone I served loved it! I added some crushed red pepper to add a kick the last couple hours!

  2. Dgould says:

    4 stars
    Maybe half a can of pineapple, felt like there was as much as chicken. Flavor was great, cornstarch thickened it perfectly. I might seat my chicken next time, but very good recipe!

  3. Kelly J says:

    5 stars
    I have made this recipe almost a dozen times it is my family’s absolute favorite. I seldom do fresh garlic and ginger and it has never sacrificed the taste. I made it once with chicken breast because that is what I had at the time and it was pretty good still! Thighs are better though, much more tender and juicy. I like to add extra bell peppers of all colors!

  4. Ed says:

    Can chopped up rotissere chicken be uses

    1. Valerie Brunmeier says:

      No. Cooked chicken would not work in this recipe.

  5. Rhonda C says:

    I can’t wait to try this! Looks soo good. Could I use ginger paste instead of ginger?

    1. Valerie Brunmeier says:

      Absolutely! Just sub an equal amount of paste. I’m ALL about kitchen shortcuts. 🙂

  6. Lorraine Fuller says:

    I want to make this but only have boneless skinless chicken breasts. How can I make that work or should I get the thighs the next time I go to the grocery store?

    1. Valerie Brunmeier says:

      Hi Lorraine. I haven’t made this recipe with boneless chicken breast and although I do think it’s better with thighs, it should work ok. Let me know how it works out for you!

      1. Mark says:

        Can you use pork instead of chicken

        1. Valerie Brunmeier says:

          I think it should work fine. Let me know how it turns out for you if you try it. 🙂

  7. Laura Donahue says:

    Wow this was delicious! I omitted the onions just due to personal preference and used boneless chicken breasts since that’s what I had on hand. Amazing flavor and love that there wasn’t sugar in the recipe.

  8. Corey says:

    5 stars
    Oh my gosh, this is so good! I love trying new recipes, but am not really to successful with the final product. This was so easy, so delicious – was looking forward to left overs, but my very picky eater beat me to them. A big win in our house! I look forward to trying more of your recipes!!

  9. Betty says:

    Can you use flour for the cornstarch?

    1. Valerie says:

      I wouldn’t recommend using flour. The cornstarch works really well to crisp up the chicken and thicken the sauce without clumping.
