Chicken and Broccoli Stir-fry

Ingredients

1 pound chicken breast (about 2 breasts), cubed
3 scallions, whites only, thinly sliced on a bias
2 tablespoons sugar
1 tablespoon dark sesame oil
1 tablespoon dry sherry
1 tablespoon soy sauce
2 cloves garlic, minced
1-inch piece peeled fresh ginger, minced
1 tablespoon, plus 1 teaspoon cornstarch
Kosher salt and freshly ground black pepper
About 1/3 cup water
3 tablespoons vegetable oil
5 to 6 cups broccoli florets and sliced stalks (keep the 2 cuts separate)
3/4 to 1 teaspoon red chili flakes, optional
1 tablespoon hoisin sauce
Toasted sesame seeds, for serving, optional
Jasmine rice, for serving, optional

Directions

In a medium bowl, toss the chicken with the scallion whites, sugar, sesame oil, sherry, soy sauce, about half the garlic, half the ginger, 1 teaspoon of the cornstarch and 1 teaspoon salt. Marinate at room temperature for 15 minutes. Mix the remaining 1 tablespoon cornstarch with 1/3 cup water in a small bowl and reserve.

Heat a large nonstick skillet over high heat. Add 1 tablespoon of the vegetable oil and heat. Add the broccoli stems and stir-fry for 30 seconds. Add the florets and the remaining garlic and ginger, 2 tablespoons water, 1/4 teaspoon salt and some black pepper. Stir-fry until the broccoli is bright green but still crisp, about 2 minutes. Transfer to a plate.

Get the skillet good and hot again, and then heat the remaining 2 tablespoons vegetable oil. Add the chicken and red pepper flakes if using. Stir-fry until the chicken loses its raw color and gets a little brown, about 3 minutes. Add the hoisin sauce, return the broccoli to the pan and toss to heat through. Stir in the reserved cornstarch mixture and bring to a boil to thicken. Add more water if need to thin the sauce, if necessary. Taste and season with salt and pepper, if you like.

Mound the stir-fry on a serving platter or divide among 4 plates and garnish with sesame seeds; serve with rice.
