Crockpot Sweet and Sour Chicken is the dinner that gets requested by name in this house, mostly because pineapple chunks showing up in a savory dinner always feels like a treat. Chicken breasts cook with bell peppers and pineapple in a tangy ketchup-and-vinegar sauce until everything’s tender, then a cornstarch slurry pulls it into a glossy glaze.

The vinegar is what actually earns this dish its name. Where our other Asian-style crockpot chickens lean sweet, this one balances real tang against the sweetness from the ketchup, brown sugar, and pineapple juice, which is the genuine sweet-and-sour profile, not just a sweet sauce with a misleading name.

Pineapple and bell peppers also make this one of the most visually distinct dishes in the whole cluster: bright chunks of fruit and colorful pepper strips instead of just glossy shredded chicken.

Why You’ll Love This Recipe

• Actually tangy, not just sweet. Real vinegar balances the sweetness, matching the dish’s actual name.
• Pineapple makes it feel special. Bright fruit and colorful peppers give it a genuinely different look and bite.
• Dump-and-go simple. Everything, including the pineapple, goes in the pot together.
• A kid-favorite by request. The sweet-tangy sauce and fun pineapple chunks are an easy sell at the table.

Crockpot Sweet and Sour Chicken Ingredients

• 2 lbs boneless, skinless chicken breasts, cut into chunks
• 1 (20 oz) can pineapple chunks, with juice
• 1 bell pepper, cut into strips
• 1/3 cup ketchup
• 1/4 cup brown sugar
• 3 tbsp rice vinegar
• 2 tbsp low-sodium soy sauce
• 3 cloves garlic, minced
• 2 tbsp cornstarch + 2 tbsp water

Recipe Variations

• Chicken thighs work in place of breasts and stay a little juicier over the cook.
• No fresh bell pepper? Frozen pepper strips work, just add them for the last hour of cooking rather than the full time.
• For a version closer to the restaurant-style deep-fried texture, pan-fry the sauced chicken in a hot skillet for a few minutes after saucing to crisp the edges slightly.

How to Make Crockpot Sweet and Sour Chicken

1. Combine the sauce: In the crockpot, whisk together the pineapple juice (reserved from the can), ketchup, brown sugar, rice vinegar, soy sauce, and garlic.
2. Add the chicken: Add the chicken chunks and stir to coat in the sauce.
3. Cook: Cover and cook on low for 5 hours or high for 2.5 hours, until the chicken is tender and reaches 165°F.
4. Add the pineapple and peppers: Stir in the pineapple chunks and bell pepper strips. Cover and cook on high for another 30-45 minutes, until the peppers are tender-crisp.
5. Thicken the sauce: Whisk the cornstarch and water together, stir into the pot, and cook on high, uncovered, for 5-10 minutes until glossy and thick.

Recipe FAQs

Can I Use Fresh Pineapple Instead of Canned?

Yes, though you’ll need to add 3/4 cup of pineapple juice or extra broth to replace what the canned version provides for the sauce base.

Do I Need to Add the Bell Peppers at the Start?

No, and it’s better not to. Adding them with the pineapple in the last 30-45 minutes keeps them from turning mushy over the full cook.

Can I Make This Ahead?

The chicken-and-sauce stage keeps well for a few days in the fridge. The peppers soften a bit more on reheating but the flavor holds up well.

Why Is My Sauce Too Thin?

The cornstarch slurry is what thickens it, so make sure that step happens after the pineapple and peppers go in, not before. If it’s still thin, whisk in another tablespoon of cornstarch and water.

What Should I Serve This With?

Steamed white rice is the classic pairing. It doubles fine in a 6-quart or larger crockpot; add the fruit and vegetables in the same late-stage window.

Cooking Tips

• Reserve the pineapple juice from the can rather than draining it away, it’s a key part of the sauce.
• Cut the chicken and bell peppers into similar-sized pieces so everything cooks evenly.
• Don’t skip the vinegar. It’s what keeps this tasting like sweet and sour instead of just sweet.

Storage and Freezing

To store: Keep in an airtight container in the fridge for up to 4 days.

To freeze: Freeze for up to 3 months, though the peppers and pineapple will soften more on thawing. Thaw overnight in the fridge.

To reheat: Warm in a skillet over medium-low heat, stirring occasionally, or microwave in 30-second bursts.
