Wholesome Ingredients for This Cheesy Roasted Cabbage

Each ingredient was chosen with both flavor and nutrition in mind. Here are the key players:

Green cabbage: Cabbage is low in calories but high in nutrients like vitamin C, vitamin K, and antioxidants. To choose a great cabbage, look for one that’s firm and heavy for its size.
Sweet onion: Caramelizing onions brings out their natural sweetness, adding depth to the dish. Swap for yellow onions if needed, but the sweetness of a Vidalia or similar variety works best here.
Gruyère cheese: Known for its nutty, creamy flavor, Gruyère melts beautifully over the roasted cabbage for an indulgent finish. If you prefer, swap it for mozzarella or a dairy-free shredded cheese to meet dietary needs.
Extra-virgin olive oil: A heart-healthy fat that enhances the cabbage’s caramelization while keeping it tender. Use high-quality olive oil for the best results.

Tip: Fresh thyme is a flavor-enhancing hero here, but if you’re out, dried thyme works as a substitute (just use less, as dried herbs are more concentrated).

Ingredients for Cheesy Roasted Cabbage

1 large head green cabbage, cut into 8 wedges with core intact
5 tablespoons extra-virgin olive oil, divided
½ teaspoon garlic powder
½ teaspoon salt
½ teaspoon ground pepper, divided, plus more for garnish
1 large sweet onion, halved and thinly sliced
2 teaspoons chopped fresh thyme, plus fresh thyme leaves for garnish
1½ teaspoons reduced-sodium soy sauce
¼ cup reduced-sodium vegetable broth
1 tablespoon sherry vinegar or cider vinegar
1 cup shredded Gruyère cheese

How to Make Cheesy Roasted Cabbage

Preheat your oven to 425°F and coat a large rimmed baking sheet with cooking spray.
Place the cabbage wedges on the prepared sheet in an even layer.
In a small bowl, whisk 3 tablespoons olive oil, garlic powder, salt, and ¼ teaspoon pepper. Brush the mix evenly over the cut sides of the cabbage.
Roast the cabbage for approximately 20 minutes until golden-brown on the edges. Flip the wedges and continue roasting for another 20 minutes, or until crisp-tender.
Meanwhile, heat the remaining 2 tablespoons olive oil in a skillet over medium heat. Add the onions and cook, stirring occasionally, until softened (about 5 minutes).
Stir in thyme, soy sauce, and the remaining pepper. Lower heat to medium-low and continue cooking the onions, stirring occasionally, until golden-brown (15–20 minutes).
Add broth and vinegar to the onion mixture. Use a spoon to scrape up any browned bits at the bottom of the pan, then cook for 1–2 minutes, or until the onions are glossy and most of the liquid is absorbed.
Top each roasted cabbage wedge with caramelized onions, using about 1 heaping tablespoon per wedge.
Sprinkle cheese evenly over the wedges, then return the tray to the oven and roast for 3 minutes, or just until the cheese is melted and bubbling.
Garnish with fresh thyme leaves and a sprinkle of black pepper. Serve immediately!
