Equipment for this slow cooker sweet and sour chicken recipe:
- Crockpot I used a 2.5 quart casserole crockpot in this recipe and it was a tad on the small side, which is why I recommend using a 3-4 quart crockpot. *note if using a larger crockpot the cubed chicken may cook a little faster too.
- Sauce pan a small saucepan is handy for whipping up a sauce such as this sweet and sour sauce.
- Cutting board I like to use a plastic cutting board that is dish washer friendly when cubing chicken and chopping veggies. *tip: be sure to clean the cutting board with hot water and soap between cubing the chicken and chopping the vegetables, to avoid spreading bacteria onto the veggies and pineapple.
- Chef’s knife A large chef’s knife makes the chopping and cubing process so much easier and also faster!

Ingredients needed: Pineapple chunks, chicken breast, mini bell peppers, brown sugar, pineapple juice, apple cider vinegar, ketchup, cornstarch, soy sauce, garlic powder and ground ginger. Optional ingredients: spring/green onions and sesame seeds.
Substitutions:
You can also use roughly 1 cup diced, regular sized bell peppers. Yellow or red bell peppers will be sweeter, but green bell peppers can also be used.
You can also saute diced white or yellow sweet onions with the peppers instead of adding spring onions for garnish.

Step 1: Create the sauce by combining all the sauce ingredients except the cornstarch. Create a slurry of cornstarch and water, then bring the combined ingredients in the saucepan to a boil and whisk in the cornstarch slurry. Cook until the sauce is thickened and clear (the sauce should return to its original dark color).
Note*
The first time I tried sweet and sour chicken in the slow cooker I added the sauce with cornstarch without cooking it prior. The slow cooker does not cook hot enough (unless it happens to have a boil setting) to cook the corn starch properly and I ended up with a gritty, weird textured chicken mixture (I may have gagged a few times). So, please be sure to cook the sauce and cornstarch together before adding it to the crockpot to get the sauce nice and smooth.

Step 2: Place the cubed, sweet and sour chicken into a 2.5-4 quart crockpot and pour the sauce over top. Cook on low for 2-3 hours.
Note*
Be sure to avoid over cooking the cubed chicken, which will cook a lot faster than whole breasts and will have a dry/gummy texture if overcooked. My chicken is usually done right around 2 1/2 hours, but if you are using a crockpot that is larger than a 2.5 quart, it may cook faster. As soon as the chicken reaches 165 degrees Fahrenheit, it is ready to enjoy.

Step 3: Saute the peppers separately, then add to the cooked, sweet and sour chicken along with the pineapple chunks.
Note*
Cooking the peppers with the chicken in the crockpot can add a strong pepper flavor to the sweet and sour sauce and the chicken. Which is why I prefer to saute the peppers separately. If you do not mind a strong pepper flavor in the sweet and sour chicken, you can skip the sauteeing step and add the peppers into the crockpot with the raw chicken, or at the last hour of cooking for more crisp-tender peppers.

Step 3 continued: Combine the chicken, pineapple chunks and sauteed peppers, then the sweet and sour chicken is ready to serve.
