Preheat your oven to 400°F (200°C). Ensure the oven rack is in the middle position for even roasting.
Toss the broccoli florets with olive oil, salt, and pepper in a mixing bowl. Make sure each floret is lightly coated so they roast evenly.
Spread the broccoli on a baking sheet, leaving space between each piece. Use a single layer to promote browning rather than steaming. If you have parchment paper, line the sheet for easier cleanup.
Roast for 15-20 minutes until tender and lightly charred. Check at 12 minutes if your florets are small — you want a bit of golden color and slightly crisp tips.
Remove from the oven and smash the broccoli with a fork or potato masher to your desired consistency. Press gently for large, rustic breaks or more firmly for nearly mashed florets. Taste and adjust seasoning.
Notes
For extra flavor, add a squeeze of lemon juice or a sprinkle of grated Parmesan right after smashing. Avoid over-salting early; season gradually and taste after smashing.
