Step‑by‑Step Instructions for Savory Roasted Cauliflower with Parmesan and Pesto
Step 1: Preheat and Prepare
Begin by preheating your oven to 425°F (220°C). While the oven heats, line a baking sheet with parchment paper to prevent sticking. This simple preparation paves the way for perfectly roasted cauliflower. The parchment paper will also help maintain crispiness while enhancing the flavors of your Savory Roasted Cauliflower with Parmesan and Pesto.
Step 2: Toss the Cauliflower
In a large mixing bowl, toss the cauliflower florets with olive oil, garlic powder, salt, and black pepper. Use your hands or a wooden spoon to ensure each floret is evenly coated with the seasonings. This step is crucial, as it provides the foundation of flavor for your dish. Once fully coated, the cauliflower will be ready for roasting, bringing you closer to that delicious Savory Roasted Cauliflower with Parmesan and Pesto.
Step 3: Spread and Roast
Spread the seasoned cauliflower florets onto the prepared baking sheet in a single layer. Make sure they have some space in between to allow for even roasting. Place the baking sheet in the preheated oven and roast for 20 minutes. Watch for the florets to start turning golden and becoming tender, signaling that they’re on their way to being the star of your side dish!
Step 4: Add Parmesan
After 20 minutes, carefully remove the baking sheet from the oven. Sprinkle the grated Parmesan cheese generously over the roasted cauliflower. The cheese will melt and create a beautiful, savory crust as it continues to cook. Pop the baking sheet back in the oven for an additional 10 minutes or until the edges of the cauliflower are golden brown and the cheese is bubbly.
Step 5: Final Touches
Once the roasting time is complete, transfer your perfectly roasted cauliflower to a serving platter. Drizzle the vibrant basil pesto over the top for an extra burst of flavor. This step elevates your dish and vibrant color, signaling that your Savory Roasted Cauliflower with Parmesan and Pesto is ready to shine.
Step 6: Garnish and Serve
To finish, sprinkle fresh lemon zest, toasted pine nuts, and chopped parsley over the roasted cauliflower. This adds an appealing crunch and freshness to each bite. The beautiful combination of colors and flavors makes this dish irresistible. Now, your Savory Roasted Cauliflower with Parmesan and Pesto is ready to be enjoyed by family and friends!
