Step‑by‑Step Instructions for Thanksgiving Cauliflower
Step 1: Preheat the Oven
Start by preheating your oven to 400°F (200°C). This temperature is ideal for achieving that perfect golden-brown crust on your Thanksgiving cauliflower. While the oven warms, you can gather your ingredients and prepare your baking sheet with parchment paper for easy cleanup later.
Step 2: Prepare the Cauliflower
Trim the leaves from the cauliflower, making sure to leave the core intact for stability. Steam the cauliflower for about 10 minutes until it is just tender but still holds its shape. This step ensures that your cauliflower will roast evenly, turning beautifully golden while maintaining a perfect texture during your Thanksgiving feast.
Step 3: Season the Cauliflower
Once steamed, carefully place the cauliflower on the prepared baking sheet. Brush the entire surface with melted butter, ensuring an even coating for flavor and browning. Generously season it with kosher salt and freshly ground black pepper, enhancing its natural taste. The initial seasoning sets the stage for a delicious, savory Thanksgiving cauliflower.
Step 4: Roast the Cauliflower
Roast the cauliflower in the preheated oven for 30 to 40 minutes. Be sure to baste it halfway through the cooking time with the melted butter to achieve an even darker and more flavorful crust. Keep an eye on it; the goal is a tender interior surrounded by a crispy, golden exterior that looks inviting as the star of your Thanksgiving table.
Step 5: Make the Gravy
While your Thanksgiving cauliflower roasts, melt additional butter in a skillet over medium heat. Add finely chopped onions and cremini mushrooms to the skillet, sautéing for about 5 to 7 minutes until they soften. This mixture will create a flavorful base for your rich vegetarian gravy that perfectly complements the roasted cauliflower.
Step 6: Thicken the Gravy
Once the onions and mushrooms are tender, sprinkle in flour and let it cook for one minute to eliminate the raw taste. Gradually whisk in low-sodium vegetable broth, allowing it to thicken as it heats. Stir continuously to prevent lumps, ensuring a smooth, savory gravy ready to elevate your Thanksgiving cauliflower dish to new heights.
Step 7: Final Herb Infusion
After the gravy has thickened, stir in freshly chopped sage, rosemary, and thyme to enhance the herbal notes. Taste your gravy and adjust the seasoning as necessary, balancing with additional salt or pepper if desired. This rich, herby gravy is the perfect finishing touch that ties together your Thanksgiving cauliflower and adds festive flavors.
Step 8: Serve and Enjoy
Remove the roasted cauliflower from the oven once it is beautifully browned and tender. Place the whole cauliflower on a serving platter and generously pour the made gravy over it. This stunning Thanksgiving centerpiece promises to wow your guests, inviting them to share in the warmth and flavor of your holiday meal.
