Heat 1 tablespoon olive oil in a large ovenproof skillet over medium-high heat. Add 4 cabbage wedges and cook until deeply browned on both sides, about 5 minutes per side. Transfer to a plate and season both sides with ⅛ teaspoon salt and ⅛ teaspoon pepper.

Repeat the same process with 1 more tablespoon olive oil, the remaining cabbage wedges, and ⅛ teaspoon each salt and pepper. Transfer browned wedges to the same plate.

Reduce heat to medium. Add the remaining 2 tablespoons olive oil to the same skillet. Add sliced onion, garlic, Italian seasoning, and crushed red pepper. Cook, stirring often, until onion is softened and lightly browned, 2-3 minutes.

Mix cornstarch and water in a small bowl until smooth. Whisk this slurry into the skillet. Remove skillet from heat and whisk in ½ cup grated Parmesan until fully melted.

Return cabbage wedges to the skillet, overlapping them as needed. Transfer to the oven and bake, turning once, until very tender and the sauce is thickened, about 50 minutes.

Let the dish rest for 5 minutes. Sprinkle the remaining ½ cup Parmesan over the cabbage wedges and garnish with chopped parsley if desired before serving.
