There’s something deeply comforting about the scent of sweet and sour sauce bubbling away in the kitchen—like a warm hug after a long day. I still remember the first time I tried to recreate that perfect balance of tangy vinegar, sticky-sweet sugar, and tender chicken at home. It was a rainy Tuesday evening, I was juggling work calls with a toddler’s dinner requests, and takeout felt like both a treat and a necessity. That’s when my Crockpot Sweet and Sour Chicken was born: minimal hands-on time, maximum flavor, and no guilt about late-night delivery fees.
Whether you’re a slow-cooker novice or a seasoned crockpot queen (or king), this recipe is designed to simplify your weeknight routine. You’ll start with basic pantry staples—cornstarch, eggs, sugar, vinegar, ketchup—and end up with bite-sized chicken morsels coated in a glossy, tangy sauce, studded with crisp bell peppers and juicy pineapple. The slow cooker does the heavy lifting, freeing you to tackle whatever life throws your way: homework help, evening dog walks, or just kicking back with a good book.
Over the years, I’ve experimented with every shortcut and tweak imaginable—skipping the sear (it still works, but a quick skillet brown makes all the difference), swapping pineapple for mandarin oranges (fun, but not the same!), and even adding a splash of sriracha for a cheeky kick. Today, I’m sharing my favorite version, complete with tips to adapt it to your pantry and spice preferences.
Ready to dive in? Let’s gather our ingredients, fire up the skillet, and get that slow cooker humming.
STEPS
Prep the Chicken
Cut 1½ pounds of boneless, skinless chicken breasts into bite-sized pieces—about 1½ inch cubes.
Set up a simple dredging station: one shallow bowl with 1 cup of cornstarch, and another with 2 beaten eggs.
Working in batches, coat each piece of chicken in cornstarch (shake off the excess), then dip into the egg. This double layer helps the chicken develop a light, crispy exterior that holds onto the sauce beautifully.
Sear for Flavor
Heat ¼ cup of vegetable oil in a large skillet over medium-high heat.
Add the chicken pieces in a single layer—don’t overcrowd the pan. Sear each side for about 1–2 minutes until lightly golden. You’re not cooking them through; you just want a quick crust.
Transfer the browned chicken to your crockpot as you go, keeping the skillet on the heat for the sauce.
Mix the Signature Sauce
In a medium bowl, whisk together:
1 cup granulated sugar
½ cup apple cider vinegar
¼ cup ketchup
2 tablespoons soy sauce
1 teaspoon garlic powder
Taste—and if you crave extra tang, add a splash more vinegar; for more sweetness, another teaspoon of sugar. This is your chance to nail the balance.
Assemble & Set to Slow Cook
Pour the sauce straight over the chicken in the crockpot, giving it a gentle stir to coat every piece.
Cover and cook on Low for 4 hours or High for 2 hours. The chicken will simmer away, absorbing the sweet and sour notes while you tackle the rest of your evening.
Adding Color, Flavor, and Finishing Touches
When that slow cooker timer pings, you’ll be greeted by the mouthwatering aroma of tangy sauce and tender chicken—but we’re not quite done yet. In this section, we’ll bring in the vibrant bell peppers and juicy pineapple, learn how to achieve the perfect sauce consistency, and explore a few simple tweaks to tailor this dish to your tastes. Trust me, these final steps are where the magic happens.
STEPS
Midway Mix-In
At the halfway point (about 2 hours on Low or 1 hour on High), remove the lid and stir in:1 red bell pepper, chopped into bite-sized pieces
1 green bell pepper, likewise chopped
1 cup pineapple chunks, drained if canned or patted dry if fresh
These add-ins not only boost color and freshness, but also lend a contrasting crunch and tang that keeps every bite interesting. Give everything a gentle stir—don’t worry if a little sauce drips down the sides of the crockpot; it’ll all come together just fine.
Final Simmer & Sauce Check
Replace the lid and continue cooking for the remaining time. As the peppers soften and the pineapple releases its juices, the sauce will gradually turn glossy and thick. If you peek and find the sauce still a bit runny, mix 1–2 teaspoons of cornstarch with an equal amount of cold water to form a slurry, then stir it into the crockpot. Replace the lid and let it cook another 10–15 minutes until the sauce coats the chicken pieces in a rich glaze.Taste & Adjust
Before serving, scoop out a piece of chicken and a few peppers to taste. You might find you want:More tang: Add a splash (1–2 teaspoons) of apple cider vinegar or rice vinegar.
More sweetness: Stir in an extra tablespoon of granulated sugar or a drizzle of honey.
A spicy kick: Sprinkle in red pepper flakes, a dash of cayenne, or swirl in sriracha.
Serving Suggestions
Spoon the sweet and sour chicken over a bed of steaming white rice, jasmine rice, or even quinoa for a protein-packed twist. Garnish with thinly sliced green onions or a sprinkle of toasted sesame seeds to elevate both the presentation and the flavor profile. Don’t forget to have extra napkins on hand—this sauce is irresistibly sticky!Make-Ahead & Storage Tips
Overnight Prep: If mornings are your jam, you can prep the chicken, dredge, and sear it the night before. Store everything in an airtight container in the fridge; in the morning, transfer to the crockpot, whisk and add the sauce, then set it on Low before you leave.
Leftovers: Cool completely, then refrigerate in a sealed container for up to 3 days. Reheat gently—either in the microwave (covered, with a splash of water to prevent drying) or in a skillet over medium heat until warmed through.
Variations to Try
Pineapple Swap: Use mandarin orange segments for a mellower citrus note.
Protein Variation: Shrimp cooks even faster—add peeled, deveined shrimp in the last 30–45 minutes on Low.
Veggie Boost: Stir in thinly sliced zucchini or snap peas at the same time you add the peppers.
Gluten-Free Option: Substitute tamari for soy sauce and rice vinegar for apple cider vinegar; double-check that your ketchup is gluten-free.
Frequently Asked Questions
1. Can I skip browning the chicken to save time?
Absolutely. If you’re in a rush, you can skip the skillet step and dump the cornstarch-coated chicken straight into the crockpot. You’ll still get tender, flavorful results, though you’ll miss a bit of that extra crust and caramelized flavor that searing provides.
2. How do I keep the bell peppers from turning mushy?
The key is adding them halfway through the cook time. If you prefer them crisper, stir them in even later—say, with 45 minutes left on High or 90 minutes on Low. This shorter cooking window lets them soften just enough without losing their bite.
3. What’s the best way to make this gluten-free?
Swap traditional soy sauce for tamari or a gluten-free soy alternative. Double-check that your ketchup and cornstarch are labeled gluten-free, and you’re all set. The flavor remains just as delicious, with none of the worry.
4. Can I freeze leftovers?
Yes! Allow the chicken to cool completely, then pack it into freezer-safe containers or heavy-duty zip-top bags. It will keep for up to 2 months. Thaw overnight in the fridge, then reheat gently on the stovetop over low heat or in the microwave, adding a splash of water or extra pineapple juice if the sauce seems too thick.
5. How can I turn up the heat?
If you love spice, stir in ½ to 1 teaspoon of crushed red pepper flakes or cayenne powder along with the sauce ingredients. For a more pronounced chili flavor, swirl in a tablespoon of sriracha just before serving. Taste as you go to avoid over-spicing.
6. What sides pair well with sweet and sour chicken?
Steamed white or jasmine rice is classic, but feel free to branch out: quinoa, cauliflower rice, or even coconut rice all work beautifully. A side of simple stir-fried greens—like bok choy or snap peas—adds color, crunch, and a hit of freshness to balance the sweetness.
7. My sauce didn’t thicken—what happened?
If the sauce stays thin, it may need more cornstarch. Mix 1–2 teaspoons of cornstarch with cold water to form a slurry, then stir it into the crockpot. Let it cook an additional 10–15 minutes with the lid on, and it should reach that perfect, cling-to-the-chicken consistency.
Conclusion
There you have it: a foolproof, crowd-pleasing slow-cooker recipe that delivers all the best parts of takeout—tangy sauce, tender chicken, crisp peppers, and juicy pineapple—without ever leaving your house. Whether you’re feeding a family of four or meal-prepping for the week, this Crockpot Sweet and Sour Chicken adapts to your schedule, your spice tolerance, and your pantry inventory.
Give it a whirl, and don’t be shy about making it your own. Swap in different veggies, experiment with heat, or even double the sauce for extra dipping potential. When you do, come back and let me know how it went: Did the kiddos request seconds? Did you pair it with coconut rice? I can’t wait to hear about your flavor adventures. Happy cooking!

Description
This Crockpot Sweet and Sour Chicken is a delicious, hassle-free version of a classic takeout favorite. With tender chicken chunks, a tangy homemade sauce, and vibrant bell peppers and pineapple, this dish is full of flavor and perfect for busy weeknights. The slow cooker does all the hard work while you enjoy a hearty, comforting meal with minimal effort.
Ingredients
For the chicken:
1 ½ lbs boneless, skinless chicken breasts, cut into bite-sized pieces
1 cup cornstarch
2 eggs, beaten
¼ cup vegetable oil
For the sauce:
1 cup granulated sugar
½ cup apple cider vinegar
¼ cup ketchup
2 tbsp soy sauce
1 tsp garlic powder
Add-ins:
1 red bell pepper, chopped
1 green bell pepper, chopped
1 cup pineapple chunks (canned or fresh, drained if canned)
Instructions
Coat the chicken pieces in cornstarch, then dip them into the beaten eggs.
Heat the oil in a skillet over medium-high heat. Brown the chicken pieces for 1-2 minutes on each side, working in batches if necessary. Do not cook through — this step is just to sear the outside.
Transfer the browned chicken to the crockpot.
In a medium bowl, whisk together the sugar, apple cider vinegar, ketchup, soy sauce, and garlic powder. Pour the sauce over the chicken in the crockpot.
Cover and cook on low for 4 hours or on high for 2 hours. At the halfway mark, add the chopped bell peppers and pineapple chunks. Stir gently to combine.
Once the chicken is tender and the sauce has thickened slightly, serve it hot over cooked white rice or your favorite grain.
Notes
To make this recipe even easier, you can skip browning the chicken, though it adds extra flavor and texture. For a spicier version, add a pinch of red pepper flakes or a drizzle of sriracha to the sauce. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheat well in the microwave or on the stovetop.
