Preheat oven to 425°F
Line a baking sheet with heat-resistant parchment paper.
Wash and trim the cauliflower, leaving the stem in place.
Slightly cut the bottom of the stem to allow the cauliflower to stand up.
Placing the stem on a cutting board, slice the cauliflower in half. Cut each half in half again, for a total of four equal pieces. There will be florets in addition to the steaks.
Place the steaks on the baking sheet in a single layer. Distribute the florets around the steaks.
Spray the cauliflower with olive oil spray. Sprinkle with half of the garlic and Italian seasoning. Salt and pepper as desired.
Bake for 30 minutes
If you are using any optional toppings, prepare them and set aside.
Remove partially cooked cauliflower steaks from the oven.
Spray the cauliflower and sprinkle with the remaining garlic powder and Italian seasoning.
Return to the oven and bake for another 15 minutes. Remove from the oven.
Spread the cauliflower steaks with marinara sauce.
Add toppings, if desired.
Top with cheese and bake for 10 to 15 minutes or until the cheese is melted and the cauliflower is fork tender.
You can eat the roasted florets plain or top them with sauce and cheese like the steaks.
