1) Preheat oven to 475°.
2) Toss broccoli with avocado oil (or other high-heat oil), salt, and pepper in a bowl to distribute oil well. Avoid using extra virgin olive oil as it does not handle this high heat well. Olive oil without an indication that its extra virgin can also work.
3) Place broccoli on a rimmed extra-large baking sheet prepared with parchment paper or a silicone mat. Keep some space between broccoli spears, so they roast rather than steam.
4) Roast until tender and browned, 15 – 20 minutes. Enjoy!
