How to Make Slow Cooker Mongolian Chicken Recipe

Step 1: Prep and Toss the Chicken

Start by cutting your chicken breasts into bite-sized cubes. Toss them gently in a large mixing bowl with cornstarch, baking soda, salt, red pepper flakes, and black pepper. This combination ensures your chicken ends up perfectly tender and coated, giving the dish that luscious, thick sauce everyone craves.

Step 2: Mix the Flavorful Sauce

In a separate bowl, whisk together water, rice wine vinegar, chili garlic sauce, hoisin sauce, brown sugar, minced garlic, sliced ginger, diced onions, and sweet red peppers. This rich, aromatic mixture will infuse the chicken with those iconic Mongolian flavors.

Step 3: Combine and Slow Cook

Pour the sauce over the coated chicken, toss until well combined, then transfer everything into your slow cooker. Set it on low and let it work its magic for 4.5 hours, slowly tenderizing the meat and melding the flavors into something truly mouthwatering.

Step 4: Add Broccoli and Finish Cooking

Once the initial cooking time is up, stir in the broccoli florets. Switch the slow cooker to high and let everything cook for an additional 30 minutes. This method keeps the broccoli bright and crisp-tender, balancing the soft chicken and sauce wonderfully.

Step 5: Garnish and Serve

For a restaurant-quality finish, sprinkle sliced red chili peppers and sesame seeds on top. These garnishes add contrast in color, a hint of heat, and delightful texture, making your Slow Cooker Mongolian Chicken Recipe look as good as it tastes.

Make Ahead and Storage

Storing Leftovers

Your leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. The flavors actually deepen overnight, making it perfect for next-day lunches or quick dinners. Just make sure to cool it completely before refrigerating to keep the texture intact.

Freezing

This recipe freezes wonderfully. Portion your slow cooker Mongolian chicken into freezer-safe containers or bags and freeze for up to 3 months. Thaw overnight in the fridge before reheating to preserve the tender chicken and fresh vegetable texture.

Reheating

Reheat gently on the stove over medium-low heat or in the microwave until warmed through. If the sauce has thickened too much, add a splash of water or broth to loosen it up. Stir in fresh broccoli or garnish after reheating if you prefer the veggies less cooked.

FAQs

Can I use chicken thighs instead of chicken breast?

Absolutely! Chicken thighs will add even more juiciness and richness to the dish. Adjust the cooking time slightly if using bone-in thighs, but boneless thighs work perfectly with the same timing.

Is this recipe spicy?

The Slow Cooker Mongolian Chicken Recipe has a mild to medium heat level thanks to the red pepper flakes and chili garlic sauce. You can easily adjust the spice by using less chili sauce or adding extra chili peppers if you like it hotter.

Can I make this recipe gluten-free?

Yes! Make sure you use gluten-free hoisin sauce and chili garlic sauce, as some brands may contain wheat. Most other ingredients are naturally gluten-free, making this dish easy to adapt.

What if I don’t have a slow cooker?

You can prepare this dish on the stovetop by simmering the chicken in the sauce for about 20-30 minutes until tender and cooked through, then adding broccoli at the end to steam until crisp-tender.

Can I substitute the broccoli?

Definitely! Green beans, snap peas, or even bok choy make excellent alternatives that complement the flavors and add a fresh crunch to the dish.
