Preheat oven to 400°F. Liberally spray a large baking sheet with cooking spray or brush with oil.
Trim stem of cabbage to level. Cut cabbage into 1 inch slices from top to bottom, around the core, leaving internal core intact. (You can cut out the core but, it helps the leaves stay together while slicing.)
In a small bowl mix together oil, salt, onion powder, black pepper, red pepper flakes, parsley and garlic. Mix well.
Brush liberally on all sides of cabbage steaks. Sprinkle tops with grated Parmesan cheese.
Bake for 20 minutes, rotate pan. Continue to roast another 15-20 minutes until golden, lightly charred and fork tender. You can broil for a few minutes to char further, if desired.
Serve immediately.
Notes
Cooking Spray: To lighten-up the calories in this dish a bit, you could use cooking spray or an oil spritzer in place of olive oil.
Brush with Bacon Drippings: You could also brush the cabbage with bacon grease for a smoky flavor and then top it with the crispy bacon or cooked turkey bacon.
Garlic: There's a generous amount of garlic in this dish as we're huge garlic fans. You can use more, or less, according to your personal taste and that of your family. You could also use garlic powder, instead.
Use a Combination of Oil and Butter: The amount of oil can be adapted to your personal taste or dietary needs.You can use half melted butter mixed with the olive oil. I don't recommend using butter alone for this Southern baked cabbage recipe due to its smoke point.
