Add the chopped onion to the bottom of the slow cooker. Then, place the pork chops on top.
Cover the pork chops with chopped red and yellow bell peppers.
In a medium bowl, add brown sugar, orange juice, garlic, red pepper flakes, ground ginger, ketchup, and soy sauce. Mix until well combined, and pour sweet and sour sauce over everything.
Cover and cook on high for 2½-3½ hours or on low for 4½-5½ hours.
Thirty minutes before cook time is up, remove pork chops. Add pineapple juice from the can and cornstarch to a small bowl. Whisk together until there are no lumps. Pour into the Crock-Pot and mix until well combined. Dump pineapple chunks on top. Cover and continue to cook for thirty minutes.
Serve over rice and garnish with diced green onion.
Notes
Sear the pork chops: To lock in the juices and add even more flavor, you may sear the pork chops in a skillet before you add them to the crock pot.
Don’t add the pineapple too early: Ensure that you hold off on adding the pineapple chunks. If they cook too long, they become very mushy.
Layer the pork if needed: Depending on the size of your crock pot, you may need to layer the pork. This is just fine! Keep an eye on it to make sure they cook thoroughly.
