Remove the outer leaves and cut the cabbage into wedges, leaving a bit of the core attached so the wedges stay together. Slice into eighths if the cabbage is very large.
Bring a large pot of salted water or vegetable broth to a boil and season generously with salt.
Add the cabbage and return the water to a simmer.
Cook for 8–15 minutes, until just tender. A knife inserted into the stem should slide in easily when it’s done.
Drain the cabbage in a colander set over the pot, or lay a few paper towels on a sheet pan and place the cabbage on top to absorb excess moisture.
Finish with melted butter, salt, and black pepper. Sprinkle with parsley.
Notes
Storage and Reheating: Store cooled leftover cabbage in an airtight container in the refrigerator for up to 4 days.Reheat gently in a covered skillet over medium-low heat with a little butter or olive oil. Add a splash of water if the cabbage seems dry.
