First, I slice the cabbage into wedges, keeping the core in each piece so they hold together. I drizzle them with olive oil, then season with salt and pepper. Roasting brings out a natural sweetness that makes every bite delicious.
I place the wedges on a baking sheet and roast them in a preheated oven at 425°F (220°C) for about 20 minutes. The edges become crispy while the centers stay soft. This caramelization is what makes roasted cabbage so addictive.
While the cabbage roasts, I melt butter in a small pan, sauté the onions until translucent, and stir in Dijon mustard, maple syrup, and water. I let it simmer for a few minutes until thick and glossy. The sauce is tangy, slightly sweet, and perfectly complements the roasted cabbage.
I drizzle the warm onion Dijon sauce over the roasted cabbage wedges right before serving. It clings to every edge, giving a rich flavor in every bite.
