Step 1: Prepare the Broccoli
Wash the head of broccoli thoroughly and pat it completely dry. Moisture is the enemy of a good sear, as it will steam the broccoli instead of frying it. Cut the large head into small, uniform, bite-sized florets. Don’t discard the stalk! Peel the tough outer layer with a vegetable peeler, and slice the tender inner stalk into thin, coin-shaped pieces. Set the prepared broccoli aside.

Step 2: Create the Stir-Fry Sauce
In a small bowl or liquid measuring cup, combine all the sauce ingredients: the ¼ cup of low-sodium soy sauce, 2 tablespoons of toasted sesame oil, 1 tablespoon of rice vinegar, and 1 tablespoon of honey or maple syrup. Whisk until the honey/maple syrup is fully dissolved. In a separate tiny bowl, whisk together the 1 teaspoon of cornstarch and 2 tablespoons of water until no lumps remain. Add this cornstarch slurry to the main sauce bowl and whisk everything together. Set the prepared sauce next to your stove.

Step 3: Prepare the Aromatics
Mince or thinly slice your garlic and grate your ginger. Keep them in a small bowl together, also next to the stove. If you’re using them, slice your scallions and have your toasted sesame seeds ready for garnish.

Step 4: Heat the Pan
Place a large skillet or a wok over high heat. Let the pan get very hot—this is one of the most important steps for achieving a true stir-fry texture. You’ll know it’s ready when a drop of water flicked into the pan sizzles and evaporates almost instantly.

Step 5: Stir-Fry the Broccoli
Add the 2 tablespoons of high-smoke-point oil to the hot pan. It should shimmer immediately. Carefully add the prepared broccoli florets and stalks to the pan, spreading them in a single layer. Let them cook undisturbed for 2-3 minutes to allow the bottoms to get a nice char. Then, begin to stir-fry, tossing the broccoli frequently for another 3-4 minutes. The broccoli should turn a vibrant bright green and be “crisp-tender”—tender enough to pierce with a fork, but still with a definitive bite.

Step 6: Add the Aromatics
Push the broccoli to the sides of the pan to create a small clearing in the center. Add the minced garlic and grated ginger to this clearing and sauté for 30-45 seconds, stirring constantly until they become intensely fragrant. Be very careful here, as garlic can burn quickly over high heat. Once fragrant, toss the garlic and ginger together with the broccoli.

Step 7: Add the Sauce
Give your prepared sauce a final quick whisk (the cornstarch can settle) and pour it all over the broccoli in the pan. Continue to stir and toss everything together. The sauce will hit the hot pan and begin to bubble and thicken almost immediately, thanks to the cornstarch. Cook for just 1-2 minutes, until the sauce has reduced slightly and beautifully coats every piece of broccoli in a glossy glaze.

Step 8: Garnish and Serve
Immediately remove the pan from the heat to prevent the broccoli from overcooking. Transfer the sesame broccoli to a serving platter. Garnish generously with the 1 tablespoon of toasted sesame seeds and the optional sliced scallions. Serve hot.
