Crispy bite-sized chicken tossed in a sticky, sweet and savory soy glaze. This easy Mongolian chicken recipe is ready in just 25 minutes. I shallow-fry the cornstarch-coated chicken and let the crust set before flipping so it stays crispy.
Jump to:
Mongolian chicken is a Chinese-American restaurant-style dish made with crispy chicken tossed in a sweet and savory brown sauce with aromatics.
Despite its name, it's not from Mongolia. The dish is associated with Mongolian barbecue, a quick stir-fry style that originated in Taiwan in the 1950s.
I first tried it at a downtown Chinese takeout restaurant and loved the sweet, sticky sauce so much that I ran home to recreate it.
When I make this dish for dinner, I fry the chicken in small batches to maintain the oil temperature so it browns evenly and stays crispy. Finally, I toss the chicken in the thickened sauce just before serving to keep the coating from softening too quickly.
Ingredients & Substitutes
Exact ingredient amounts are listed in the recipe card at the bottom of this page.
- Chicken Thighs: Use boneless, skinless chicken thighs because their higher fat content keeps them juicy during frying. Chicken breast also works but requires a shorter cooking time since it's leaner and more prone to drying out.
- Cornstarch: Creates a light, crispy coating on the chicken. Potato starch also works. Avoid tapioca or arrowroot starch, as they can cause the chicken to stick together.
- Vegetable Oil: Or use a neutral oil with a high smoke point, such as canola or refined avocado oil.
- Garlic: Freshly minced garlic offers the best flavor, but jarred minced garlic also works.
- Red Chili Pepper: I prefer Korean red chili peppers, but any red chili pepper works. For milder heat, remove the seeds before chopping. For a non-spicy version, use finely diced red bell pepper instead.
- Fresh Ginger: Adds a warm, slightly peppery flavor that balances the sweetness of the glaze.
- Hoisin Sauce: Gives the glaze its sweet, savory flavor. Find it at Asian grocery stores. Do not substitute oyster sauce, as it has a different flavor profile.
- Regular Soy Sauce: Adds a savory, salty flavor that balances the sweetness of the hoisin sauce and brown sugar. Light soy sauce or low-sodium soy sauce also works.
- Brown Sugar: Sweetens the glaze and balances the salty soy sauce. Light brown sugar works best, but dark brown sugar also works for a deeper molasses flavor.
- Toasted Sesame Oil: Adds a rich, nutty flavor to the glaze.
- Green Onion
Cornstarch Slurry
- Cornstarch: Thickens the sauce into a glossy glaze that clings to the chicken. Potato starch or tapioca starch also works.
- Cold Water
Note: Asian ingredients are typically available at most Asian grocery stores or online.
Expert Tips
- Use a cooking thermometer to keep the oil at 325-350°F for a crispy, evenly fried coating.
- For extra crispiness, press the cornstarch onto the chicken so the coating adheres evenly during frying.
- Coat the chicken just before frying to prevent moisture from softening the cornstarch coating.
- Shake off loose cornstarch to prevent excess starch from falling into the oil and burning.
- Remove browned bits between batches to prevent leftover cornstarch from burning and giving the chicken a bitter taste.
- Toss with sauce just before serving to prevent the crispy coating from absorbing moisture and softening.
Instructions
Below are step-by-step instructions on how to make Mongolian chicken:
- Make the slurry: In a small bowl, whisk together all the cornstarch slurry ingredients until the cornstarch is fully dissolved. Set aside.
- Dice the chicken: Dice the chicken thighs into uniform 1.5-inch pieces. Do not pat the chicken dry, as the moisture helps the cornstarch stick.
- Coat the chicken: Transfer the chicken to a large mixing bowl and add the cornstarch for coating. Toss until evenly coated. If any areas remain uncoated, add 1-2 tablespoons more cornstarch as needed.
- Fry the chicken: Heat vegetable oil in a large, heavy-bottomed pan over medium-high heat to 350°F. Fry the chicken in a single layer, working in batches if needed, for about 5-7 minutes per batch. Leave the chicken undisturbed until the bottom is golden and the crust has set before flipping. Continue frying until the internal temperature reaches 165°F. Transfer to a wire rack to keep it crispy.
- Make the sauce: Remove the excess frying oil, leaving 2 teaspoon (10 ml) in the pan. Reduce heat to medium. Stir-fry the ginger, garlic, and half of the red chilies for 10 seconds. Add the hoisin sauce, soy sauce, brown sugar, and toasted sesame oil. Stir to combine. Stir the cornstarch slurry again, then pour it in. Simmer until thickened and glossy.
- Sauce and serve: Add the chicken and toss to coat evenly. Remove from heat, garnish with the remaining red chilies and green onions, and serve immediately.
Storage & Reheating
- Refrigerator: Store leftover Mongolian chicken in an airtight container in the refrigerator for up to 3 days.
- Freezer: Let leftover Mongolian chicken cool, then transfer it to a freezer-safe bag and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating. The coating will soften after thawing.
- Reheating: Reheat in the microwave in 1-minute intervals, stirring between intervals, or in a pan over medium-low heat for about 4-5 minutes, stirring occasionally, until heated through.
Pairing Suggestions
Serve crispy Mongolian chicken stir-fry with:
- Steamed Jasmine Rice: Fluffy rice absorbs the sweet and savory sauce.
- Garlic Green Beans: Crisp-tender green beans add freshness and balance the rich glaze.
- Egg Drop Soup: A light, savory soup that complements the crispy chicken.
FAQ
Yes! Lightly spray the air fryer basket with oil. Arrange the cornstarch-coated chicken in a single layer, working in batches if needed, and spray the chicken with oil. Air fry each batch at 400°F for about 10-14 minutes, without flipping, until golden and crispy and the internal temperature reaches 165°F. Prepare the sauce as directed in the recipe card, then toss with the air-fried chicken. Serve immediately.
Yes! Substitute regular soy sauce with gluten-free tamari and use gluten-free hoisin sauce. Make sure all other packaged ingredients are certified gluten-free.
Yes! Diced bell peppers or sliced carrots work well. Stir-fry the vegetables until crisp-tender, then add the aromatics and continue with the sauce as directed.

Oh my gosh, this was so easy! The taste was like we got it from a restaurant. Cannot wait to make it again! Thank you Christie for helping us make tasty Asian dishes at home!!!!

Yummy! I couldn’t find red peppers so I substituted red pepper flakes. I will try air frying the chicken as suggested next time to improve the healthfulness. Quick and easy. Thanks so much for sharing.

Thanks so much for making my recipe, Tracy! Glad you enjoyed it!

Great taste good Dish except the directions are a little sketchy on the corn starch. It almost sounds like you are supposed to put the cornstarch slurry with the chicken. That is not the case, you are to coat chicken with corn starch. This measurement is not mentioned in the ingredients list.
christieathome
Apologies for the confusion! I've just revised the recipe instructions. I appreciate you flagging this and for making my recipe.
Bethany Hunter
I loved it!! The only problem I had was that the recipe was a little confusing with the cornstarch. First, I did it correctly by adding the cornstarch directly to the chicken, then, the next step says to make a slurry which confused me so I added water to the cornstarch coated chicken. I then realized that you meant that the slurry was for the sauce and the quarter cup was for the chicken and ended up adding more cornstarch to the slurried chicken. It ended up delicious but I bet it’s even more delicious don’t correctly.
That being said, it ended up so so so delicious! Thank you!

Thank you so much for your comment and for making my recipe! I also appreciate you flagging this. I've revised the instructions again so they are more clearly written. Have a great day, Bethany!

We loved this recipe but could not figure out where the green onions mentioned in the first section went with the recipe. We ended up throwing them in with the aromatics, but the recipe is not clear.
christieathome
Thanks for making my recipe and for flagging that! I've corrected the recipe, the green onions are just for garnish.

Deliciously sweet and spicy.
My first time making this but it’s definitely not a 25 min meal. I prepped the ingredients (added carrots, peppers and onions) and began frying. It took time working in small batches. I’ll be trying the air fryer next time.

Hoisin sauce and sugar? Is this dish too much sweet?
Patryk
Hoisin sauce is generally sweet, wouldn't adding sugar make a dish bland and too sweet?
christieathome
Not in my experience with this dish and I haven't received that feedback from the many others who made this dish through my other social platforms. But if you feel it's too sweet, omit it and you can always add it later to the sauce.

Recipe as-is is great. Very nice flavor and the Corn Starch crisped chicken was just right. Wife didn't want it with rice so I used some Chinese egg noodles (like Lo Mein Noodles but just a little thicker). Cooked them most of the way first then rinsed under cold water and set aside. After cooking everything I added the noodles into my wok and mixed it well and cooked everything together a little longer. The sauce clung to the noodles nicely and it turned out great....And then...my wife said she would have liked some other vegetables in it... sometimes, you just can't win.
This recipe results in a very good Mongolian chicken, with what tastes like an authentic sauce and the perfect texture on the chicken.

Thanks so much for making my recipe and for this kind review, Dan! So glad you enjoyed it! Egg noodles are a great pairing with this dish!

I've made this recipe twice but I still can't manage to get the chicken crispy. Any tips? Thanks!
christieathome
Hi there! Thank you so much for making my recipe! Here are some tips to get that chicken crispy:
1) If there is a lot of moisture on the chicken, pat it dry with a clean paper towel. The excess moisture can attribute to a less crispy crust.
2) When coating the chicken with starch, do not overmix. If you overmix, this can create moisture in the starch. Once I pour the starch onto the chicken, I use kitchen tongs and twist it 3-4 x and this evenly distributes the starch. Alternatively, instead of pouring the starch onto the chicken, you can dredge each piece of chicken into the starch to avoid overmixing.
3) Fry the chicken for a couple minutes longer until the crust is crispier. Because it's chicken thigh, this cut is more forgiving and if you do cook it for longer, it won't dry out like breast.
Hope these tips help!
