Preheat the oven: Set to 425°F (220°C). Place a large sheet pan inside to heat while you prep.
A hot pan helps with browning.
Prep the broccoli: Dry the florets well. Moisture prevents crisping. Cut large pieces so they roast evenly but still have some bite.
Make the seasoning: In a bowl, whisk neutral oil, sesame oil, soy sauce, rice vinegar, honey, garlic, ginger, and red pepper flakes.
Toss to coat: Add broccoli to the bowl and toss until every floret is glossy.
Sprinkle with 1 tablespoon sesame seeds and toss again. Season lightly with salt and pepper.
Roast: Carefully remove the hot sheet pan and spread the broccoli in a single layer, cut sides down when possible. Don’t crowd the pan.
Cook time: Roast 15–18 minutes, stirring once around the 10-minute mark.
You’re aiming for browned edges and a tender stem with a little snap.
Finish: Sprinkle the remaining sesame seeds over the hot broccoli. Taste and adjust with a squeeze of lemon, a pinch of salt, or an extra drizzle of sesame oil.
Serve: Enjoy right away while it’s at peak crispness.
