Preheat oven to 425 degrees F. Clean broccolini and cut off ends and trim leaves.

Add broccolini to a baking sheet and drizzle with 2 tablespoons olive oil. Season with ½ teaspoon salt and ¼ teaspoon black pepper. Toss to combine.

Roast broccolini in pre-heated oven for 12 to 14 minutes until ends just start to char but not burn.

Meanwhile, add 3 tablespoons gochujang paste, 1½ tablespoons rice vinegar, 1 tablespoon sesame oil and 1 tablespoon maple syrup to a bowl. Whisk together until everything is well incorporated.

For serving, spoon Gochujang Sauce onto a platter. Place roasted broccolini on top and garnish with zest of 1 lemon and toasted sesame seeds. Serve.
