Get your oven nice and hot by preheating it to 425°F. This high heat will help get those lovely golden edges on the cauliflower.

Grab a 9x13 inch stoneware casserole dish and toss your cauliflower florets with olive oil until well-coated. Sprinkle with Italian herbs, sea salt, and black pepper, then spread everything out into a single layer.

Pop the dish in the oven and let the cauliflower roast for about 25 minutes. Give it a gentle toss halfway through. You'll know it's ready when the florets are tender and getting those delicious golden spots. Keep the oven on after you take it out!

Pour the marinara sauce evenly over your roasted cauliflower. Next, sprinkle a generous layer of shredded mozzarella all over. Finally, arrange those pepperoni slices on top just like you would on a pizza.

Return the casserole to your hot oven for another 10-15 minutes, until the cheese gets all melty, bubbly, and develops those irresistible golden spots.
