Step‑by‑Step Instructions for Easy Roasted Cabbage with Amazing Onion Dijon Sauce
Step 1: Preheat the Oven
Begin by preheating your oven to 450°F (232°C). While the oven heats, prepare a baking sheet by lining it with parchment paper or a silicone mat. This will prevent sticking and ensure easy cleanup. The goal here is to create an ideal environment for roasting, where your cabbage will develop beautifully crispy edges.
Step 2: Prepare the Cabbage Wedges
Next, take a medium green cabbage (about 1½ pounds) and slice it into four equal wedges. Using a brush, generously coat each wedge with olive oil, ensuring both sides are well covered for enhanced flavor. Sprinkle salt and pepper to taste on the wedges, distributing it evenly for a perfectly seasoned layer that complements the natural sweetness of the cabbage.
Step 3: Roast the Cabbage
Place the cabbage wedges on the prepared baking sheet, making sure they are spaced out for even cooking. Roast in the preheated oven for 10-12 minutes until the edges begin to brown and crisp up. After this initial time, carefully flip the wedges over and roast for another 8-10 minutes. Keep an eye on them; you want them to be nicely browned with some deliciously crispy edges.
Step 4: Prepare the Onion Dijon Sauce
While the cabbage is roasting, it’s time to whip up the amazing onion Dijon sauce. In a small saucepan, melt butter over medium heat. Once melted, add minced fresh onion, minced garlic, salt, and pepper. Stir the mixture gently for about 3-4 minutes, allowing the onions to become translucent and fragrant. Then, stir in the Dijon mustard, mixing well for a rich flavor.
Step 5: Serve the Roasted Cabbage
After the cabbage has achieved a beautiful golden-brown exterior, remove it from the oven and transfer the wedges to a serving platter. Give the sauce one final whisk to ensure it’s well combined, then drizzle it generously over the hot roasted cabbage. For a pop of color and fresh flavor, sprinkle chopped chives or parsley on top as a finishing touch, making this easy roasted cabbage dish truly stand out.

Make Ahead Options
These Easy Roasted Cabbage with Amazing Onion Dijon Sauce are perfect for busy weeknights! You can prepare the cabbage wedges up to 24 hours in advance by cutting and seasoning them, then storing them in an airtight container in the refrigerator. The onion Dijon sauce can also be made ahead and stored for up to 3 days; just refrigerate it in a separate container. To maintain quality, reheat the cabbage in the oven at 425°F (220°C) for about 10 minutes before serving, then drizzle the whisked sauce over the top. With these make-ahead tips, you’ll have a delicious side dish ready with minimal effort!
