Method
 

Prep the Broccoli 🥦
  1. Cut broccoli into even florets.
  2. Dry thoroughly using a kitchen towel (moisture prevents proper roasting).
Preheat the Oven & Sheet Pan 🔥
  1. Set oven to 425°F (218°C) and place a baking sheet inside.
  2. Preheating the pan ensures immediate caramelization.
Season the Broccoli 🧂
  1. Toss broccoli in a bowl with olive oil, salt, pepper, and garlic.
  2. Ensure every piece is evenly coated.
Roast the Broccoli 🍽️
  1. Carefully spread broccoli on the hot baking sheet in a single layer.
  2. Roast for 15–20 minutes, without stirring, to develop crispy edges.
Check for Doneness ⏳
  1. At 8 minutes, florets should be bright green with edges beginning to brown.
  2. At 12 minutes, check for sizzling and caramelization.
  3. By 15–20 minutes, broccoli should have deep golden spots with a nutty aroma.
Serve Immediately ✅
  1. Optionally, add lemon zest, Parmesan, or pine nuts for extra flavor.
  2. Enjoy while crispy!
