01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper.
02 - Cut the cabbage into 8 equal wedges, keeping the core intact so the wedges hold together.
03 - Arrange the wedges in a single layer on the prepared baking sheet.
04 - Brush both sides of each wedge with olive oil. Sprinkle evenly with salt, pepper, garlic powder, and smoked paprika.
05 - Roast for 20-25 minutes, flipping the wedges halfway through, until the edges are crisp and browned and the centers are tender.
06 - Remove from the oven. Drizzle with lemon juice and sprinkle with chopped parsley before serving.
