prep the cauliflower: preheat the oven to 425°f and line a baking sheet with parchment paper. remove the leaves from the cauliflower and trim the stem, keeping the head intact.

cut the cauliflower into 1-inch thick u0022steaks.u0022 you should get about 4 good steaks from the center of the head. smaller florets will naturally fall off, and you can roast those separately.

season and roast: brush both sides of the cauliflower steaks with avocado oil and season with garlic powder, italian seasoning, salt, and black pepper. place the steaks on the baking sheet and roast in the oven for 25 minutes, flipping halfway through, until golden and tender.

add the toppings: remove the cauliflower steaks from the oven and spoon marinara sauce on top of each steak. sprinkle shredded vegan mozzarella cheese generously over the marinara.

melt the cheese: return the steaks to the oven and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly.

garnish and serve: top with fresh basil, parsley or red pepper flakes for a pop of flavor. serve immediately and enjoy your pizza-inspired cauliflower steaks!
