Roasting cauliflower at high heat is one of the best methods to prepare it in my not so humble opinion. The florets soften inside while the edges dry out and take on color, creating contrast without needing batter or deep frying (although I am not against fried cauliflower either). Parmesan helps that process along, forming a delicious, umami-packed crust that clings to the surface rather than melting away.
This version uses simple pantry spices and dried herbs, keeping the preparation super-straightforward. The key is spacing: the cauliflower needs room on the pan so moisture can escape. Crowding turns it soft and pale, which defeats the point. Served with a simple marinara or another sharp dip that you like, it works as a side dish or something to snack on straight from the tray.
How to Make Parmesan Herb-Roasted Cauliflower and Marinara Dip
The oven is heated to 425°F (220°C). Two baking sheets are lined with foil and lightly coated with nonstick spray. 
Parmesan, dried garlic, onion powder, oregano, red pepper flakes, black pepper, and garlic salt are mixed together in a medium bowl.
The cauliflower florets are placed in a separate bowl and tossed with olive oil until evenly coated.
The Parmesan mixture is scattered over the cauliflower and pressed lightly onto the surface of the florets so it adheres rather than falling off during roasting.
The cauliflower is arranged in a single layer across the prepared baking sheets, leaving space between pieces.
The trays are placed in the oven and roasted for 15 minutes. The cauliflower is tossed, rotated, and returned to the oven for another 15 minutes, until tender with darkened edges and visible browning.
The cauliflower is removed from the oven and, while still hot, finished with an extra pinch of Parmesan if desired. It is served warm with marinara or another dipping sauce.

- If you don’t have dried herbs, you can substitute 1 tablespoon of fresh chopped herbs (a mix of oregano, parsley, and thyme would work well).

Frequently Asked Questions
Why is it important to space the cauliflower florets on the baking sheets?
Spacing the cauliflower florets allows moisture to escape during roasting, ensuring they become nicely browned and crispy instead of soft and pale.
Can I use fresh herbs instead of dried herbs in the Parmesan mixture?
Yes, you can use fresh herbs, but you’ll need to increase the amount since dried herbs are more concentrated; about three times the amount of fresh herbs should suffice.
What type of marinara sauce works best with this dip?
A simple, sharp marinara sauce complements the roasted cauliflower’s flavor well; you can also experiment with spicy or herb-infused marinara for added depth.
