Tip: Add cheese during the last 10 minutes of roasting to prevent it from burning.
Quantities: This recipe can easily be halved or doubled.
Make-ahead: steam, smash, and do the first roast up to 2 days in advance, and store in the fridge. When you’re ready to serve, add the cheese and roast again until melted and crispy.
Storage: Leftover cheesy smashed broccoli can be refrigerated in an airtight container for up to 5 days or frozen for up to 3 months.
