How to Pick the Best Zucchini 

When it comes to picking out zucchini at the store, make sure that they’re firm and without any bruising or blemishes. Small to medium-sized zucchini are typically better in flavor, as the larger ones have a much higher water content. Always rinse and pat dry your zucchini before cooking.

This Sweet and Savory Sauce Shines 

What makes this dish so delicious is the soy sauce “slurry,” which is a combination of cornstarch and liquid. As the slurry cooks, it will gradually thicken. This mixture helps subtly thicken the stir-fry, while also providing a ton of flavor from the soy sauce, garlic, ginger, and toasted sesame oil. A couple teaspoons of sugar in the slurry adds a touch of sweetness to balance out the acidity and pungency of some of the other ingredients.

Simple Tip!

Because the soy sauce is salty, you probably won’t need to season the dish with any additional salt, but always taste the final product to decide if it needs any additional seasoning. Remember, you can always add salt, but you can’t take it away.

Delicious Variations 

  • Use any variety of summer squash. 
  • Zhush it up! Garnish it with crushed peanuts or sliced scallions.

  2. Cook the zucchini: 

    Heat the remaining 1 tablespoon sesame oil in a large skillet or wok over medium heat. 

    Sauté the onions until fragrant and softened, 3 to 4 minutes. Increase the heat to medium-high and add zucchini and prepared sauce. Toss with a rubber spatula and cook, stirring occasionally, until the sauce is thickened and the zucchini is softened, about 7 minutes.

    If you notice any deep browning on the bottom of the skillet, turn your heat down slightly and add a splash of water to help deglaze those browned bits.
