Pre-heat oven to 400F (200 C). Line a baking sheet with parchment paper or lightly oil.
In a large bowl toss together the cauliflower, olive oil, salt and garlic, then place on baking sheet, bake for approximately 25 minutes (stir after 15 minutes and continue to bake).
In a small bowl mix together parmesan cheese, breadcrumbs and parsley. Remove cauliflower from oven top with parmesan cheese mixture and broil for 3 - 5 minutes. Serve immediately. Enjoy!
Notes
How to Store Leftovers?
Store leftover roasted cauliflower Parmesan in the refrigerator in an airtight container for up to 5 days. The crispy cauliflower won’t be as crispy, but will still taste great! I love to reheat mine in the oven or air fryer to get crispy again. I would not freeze this dish as it will change texture.
