This Quick & Easy Mongolian Chicken with Spicy Broccoli is your new weeknight go-to when you want bold flavor without a ton of effort. Crispy fried chicken thighs are tossed in a rich, garlicky hoisin-soy glaze, while the roasted broccoli packs a punch with garlic, ginger, and a touch of heat from sambal oelek. It’s a fast, satisfying meal that feels like your favorite takeout, but made right at home.

The chicken gets that crave-worthy crispy texture thanks to a quick cornstarch coating and pan-fry. The sauce is thick, sticky, and savory with just a bit of sweetness. Paired with spicy, caramelized broccoli, it’s a balanced dish that checks all the flavor boxes.
Helpful Tips
- Fry in batches: Don’t crowd the pan or the chicken won’t crisp up properly.
- Use fresh aromatics: Garlic and ginger are key to both the chicken and broccoli sauces – fresh really makes a difference.
- Crank the oven for the broccoli: High heat helps it char and caramelize for extra flavor.

- Toss the fried chicken back into the pan and toss to coat in the sauce. Remove from heat. Garnish with red chilis and green onions.
For the broccoli:

what cornstarch slurry? the leftover cornstarch from when you dredged the chicken pieces? why do ingredients say chopped red chilis for garnish but then they are put into the sauce?
Lower down in the ingredient list it calls for 1 tablespoon of corn starch and 1 tablespoon of water. That will make the cornstarch slurry that will thicken the sauce. As to the red chilies, we just used them as garnish. You could stir them into the sauce if you want the heat.
