Preheat oven to 375F

Cut cabbage in half, core, then cut into quarters, then eighths- so you have 8 equal-sized wedges.

Heat oil in an extra-large (12-inch) oven-proof skillet or braiser (you’ll need a lid). Sprinkle ½ teaspoon salt, and ½ teaspoon pepper to the oil. Add a pinch of chili flakes, and swirl over medium-high heat. Sear the wedges of cabbage in batches, setting to the side on a plate, when lightly browned.

Add a little more olive oil, and lower the heat to medium. Add the onions and garlic to the empty pan and stir, then sauté until fragrant, about 2 minutes. Add the wine and bring to a simmer, scraping up any browned bits. Stir the remaining salt, bay leaves, & thyme. Nestle in the cabbage and add the broth- you want it to come halfway up the cabbage.

Drizzle the cabbage with the optional vinegar. Bring to a simmer, cover tightly and place in the oven for 30-35 minutes. Check to see if it is fork-tender, and continue cooking covered until it is. Spoon some of the flavorful pan juices over the cabbage before serving.

Make the optional  Gremolata, and set it aside. Spoon the Gremolata over the top.
