Preheat the oven to 400°F (200°C).

Slice the cabbage into thick rounds, about 1 to 2 inches wide, and arrange them on a large baking sheet lined with parchment paper.

Drizzle olive oil over the cabbage rounds and add minced garlic, salt, and pepper. Toss to ensure even coating.

Roast in the preheated oven for about 35 minutes until edges are golden-brown and center is tender.

Remove from oven, sprinkle grated Parmesan cheese over cabbage rounds, and broil for an additional 2-3 minutes until the cheese is melted and bubbly.

Let cool for a minute, then slice cabbage into wedges and serve warm.
