Creating Crockpot Orange Chicken is simple if you follow these easy steps:

1. Prepare the Chicken: Place the chicken thighs in the bottom of the crockpot.
2. Mix the Sauce: In a bowl, combine orange juice, soy sauce, honey, rice vinegar, garlic, ginger, sesame oil, and red pepper flakes (if using). Stir until well mixed.
3. Add the Sauce: Pour the sauce over the chicken in the crockpot, ensuring the chicken is well coated.
4. Cook: Cover the crockpot and cook on low for 4-6 hours or on high for 2-3 hours, until the chicken is tender and cooked through.
5. Thicken the Sauce: About 30 minutes before serving, mix cornstarch and water in a small bowl to create a slurry. Stir this mixture into the crockpot to thicken the sauce.
6. Shred the Chicken: Once cooked, shred the chicken using two forks and stir it back into the sauce.
7. Serve: Allow the chicken to sit for a few minutes to absorb the flavors before serving.

These clear steps will guide you in creating this incredible dish effortlessly.
