How To Make Mongolian Chicken In The Slow Cooker
Prepare the chicken: Pat the chicken breast dry with a paper towel and chop into bite-sized pieces. Place it into a large Ziploc bag along with the cornstarch and shake until the chicken is fully coated before adding it to the bottom of your slow cooker.
Whisk the sauce: In a medium-sized mixing bowl, add the sesame oil, garlic, ginger, hoisin sauce, water, brown sugar, and red pepper. Whisk until there are no longer any lumps. Then, pour over the chicken.
Cover and cook: Add the bell pepper and carrot to the top of the chicken. Then add the lid to the top and cook on HIGH for 2½ to 3½ hours or on LOW for 4-5 hours.
Add the vegetables: 30 minutes before the cooking time is up, stir in the broccoli and cook until tender.
Garnish and serve: Ladle over rice or noodles and garnish with sesame seeds and green onions. Enjoy!
- Shaking the chicken with cornstarch will help the sauce to coat it evenly and prevent it from clumping together.
- Adding the vegetables in towards the end of cooking will help them to retain their color, texture, and nutrients.
- Instead of water, try using chicken broth to add additional flavor to the sauce.
- Ensure that the chicken pieces are all cut to the same size to evenly cook.
Variations & Substitutions
- Can't find hoisin sauce? Try using oyster sauce, teriyaki sauce, or BBQ sauce as a substitute.
- Kick up the heat. Double the amount of red pepper flakes or add in a diced jalapeño when you whisk the sauce together.
- Use other types of veggies in this dish including snow peas, green beans, or bok choy.
- Instead of chicken breast, you can use chicken thighs, shrimp, or even thinly sliced beef.
- Try using other types of sweeteners instead of brown sugar such as honey or maple syrup.
Storing & Freezing
Storing: Once cooled, leftovers can be stored in an airtight container in the fridge for 3-4 days.
Reheating: Reheat individual portions in the microwave or heat leftovers up in a saucepan on the stove over medium heat until warm.
Freezing: Add cooled leftover Mongolian chicken to a freezer-safe bag or container and store in the freezer for up to 3 months. Keep in mind that the vegetables may change their texture and become softer.
Shaking the chicken with cornstarch before adding it to the crock pot will help to create a barrier between the sauce and the chicken so that it doesn't dry out.
Mongolian chicken is often served over steamed rice or noodles, but it can also be paired with cauliflower rice, steamed vegetables, or a simple salad.
To make this crock pot Mongolian chicken vegetarian or vegan, simply substitute the chicken for extra firm tofu, tempeh, or seitan. You can also add in more vegetables such as mushrooms, zucchini, or eggplant.
