Preheat your oven to 400 degrees Fahrenheit. This ensures that your roasted broccolini gets that perfect crispy edge while remaining tender on the inside.
Line a baking sheet with parchment paper. This will prevent the broccolini from sticking and make cleanup a breeze.
Lay the broccolini on the baking sheet in a single layer. Give each stalk enough space to roast evenly without overcrowding.
In a small bowl, combine the olive oil, lemon juice, minced garlic, grated parmesan, and a sprinkle of salt and pepper. Whisk them together until well mixed.
Pour the mixture over the laid-out broccolini. Take your time to ensure each piece is coated evenly.
Using your hands, gently rub the mixture into the broccolini to ensure it’s well coated with the flavorful marinade.
Slide the baking sheet into the preheated oven and let it roast for about 10 to 15 minutes. Keep an eye on it; you want the broccolini to be tender yet crisp.
After roasting, check for doneness. The broccolini should be bright green and lightly charred. If it needs a bit more time, let it bake for an extra couple of minutes.
Once done, remove the baking sheet from the oven and let the broccolini cool slightly before serving. This resting time allows the flavors to settle.
Serve immediately as a side to your favorite main dishes. Enjoy the harmony of flavors!
