Preheat oven to 425°F/220°C
Line baking sheet with parchment paper
Toss broccoli florets with olive oil and sea salt. You can do this in a separate bowl, or save yourself the extra dishwashing and do it right on the baking sheet. Spread the broccoli florets in a single layer on the baking sheet.
Roast at 425°F for 15 minutes until broccoli is charred on the bottom, then flip the florets. Roast for additional 10 minutes until charred on the other side.
