Step‑by‑Step Instructions for Roasted Cabbage with Amazing Onion Dijon Sauce
Step 1: Preheat the Oven
Begin by preheating your oven to a sizzling 450°F (232°C). While it’s heating, prepare a baking sheet by lining it with parchment paper or a silicone mat to ensure easy cleanup and prevent sticking. This initial step sets the stage for perfectly roasted cabbage with caramelized edges.
Step 2: Prepare the Cabbage
Next, slice the cabbage into thick wedges, aiming for about 1-inch thickness to ensure even cooking. Place the wedges on the prepared baking sheet and generously brush them with olive oil, making sure to coat both sides. Season with salt and pepper to enhance the flavor of your roasted cabbage.
Step 3: Roast the Cabbage
Transfer the baking sheet into the preheated oven and roast the cabbage for 10-12 minutes. After this initial time, flip the wedges to ensure even browning and roast for an additional 8-10 minutes. You’re looking for that delightful dark brown and crispy appearance on the edges, which indicates they are perfectly caramelized.
Step 4: Make the Sauce
While the cabbage is roasting, prepare the amazing onion Dijon sauce. In a small saucepan over medium heat, melt butter (or dairy-free margarine) until bubbly. Add the minced onion and garlic, sautéing until they become fragrant and the onion is translucent, about 3-4 minutes. This will create the aromatic base for the sauce.
Step 5: Combine Sauce Ingredients
Once the onion and garlic are ready, whisk in the Dijon mustard and season to taste with salt and pepper. Allow the sauce to heat through for another 2-3 minutes, stirring continuously to create a smooth and creamy ingredient. This rich sauce will bring an incredible tanginess to your roasted cabbage.
Step 6: Serve with a Flourish
Now that the roasted cabbage is golden and the sauce is ready, it’s time to serve. Arrange the crispy cabbage wedges on a platter and generously drizzle with your amazing onion Dijon sauce. If desired, garnish with chopped chives or parsley to add a pop of color and an extra layer of flavor to your dish. Enjoy the transformation of cabbage in this delightful recipe!
