Line a rimmed baking sheet with foil and spray it with olive oil.
Remove the cabbage’s damaged outer leaves. Cut the cabbage in half, remove any damaged outer leaves, and cut into 1/2 inch wedges as you can see in the picture. LEAVE the core in – if you cut it out the wedges will fall apart.
Place the cabbage wedges in a single layer onto the prepared baking sheet.
Mix all the seasoning ingredients in a small bowl.
Generously brush the cabbage wedges with olive oil. Season the seasoning mixture on BOTH sides.
Roast the cabbage wedges until golden brown and fork-tender, about 25-30 minutes.
Serve immediately garnished with red pepper flakes, freshly chopped parsley, and lemon on the side.
