What is Mongolian Chicken?

Similar to its Mongolian beef counterpart, Mongolian chicken is a Chinese-American favorite; hence, why you’ll find it on every Chinese restaurant menu. Whether chicken or beef, the Mongolian sauce brings flavorful life to the entire dish.

While traditional Mongolian chicken dishes call for one vegetable (green onions), adding others such as broccoli, bell pepper, or even sliced carrots has become common. It’s also familiar to pan fry it; however, it turns out just as flavorful in the slow cooker.

What do I serve with this?

Steamed white rice is often a go-to choice when ordering this dish from a Chinese restaurant. You could also go for fried rice.
Kung Pao noodles – Having many of the same ingredients as the Mongolian chicken, these noodles make a great pair to complete this dish. Not to mention, the sour-sweet soy sauce adds an extra kick.
Sesame noodles – If you’re looking for a side that won’t overpower the flavor of the Mongolian chicken, then adding a helping of sesame noodles is an ideal choice.
Stir fry veggies – Since there’s already broccoli in this recipe, adding more stir-fry-style veggies would go perfectly. These veggies often include bell peppers, sugar snap peas, baby corn, and onions.

Variations

A little more heat: If you’d like to increase the heat to your slow cooker Mongolian chicken recipe, try 3-4 tablespoons of Asian sweet chili sauce and 1-2 teaspoons of sriracha. Use more or less of each ingredient according to the amount of heat you want.
Tweak the flavor: Adding brown sugar will give your dish a sweeter taste, while adding Asian sweet chili sauce will give it a sweeter and spicier kick. Siracha adds pure spice.
Add more veggies: Besides the broccoli, you can add just about any veggie your heart desires. Stir fry veggies offer a good combination, or you could go all out with zucchini, mushrooms, asparagus, and/or cauliflower.
