How to Make Whole Roasted Cauliflower

Let me show you how easy it is to make this impressive Whole Roasted Cauliflower:

Prep Cauliflower and Oven

1. First, I preheat my oven to 400ºF (200°C).
2. I prepare the cauliflower by trimming the very bottom of the stem and removing all the outer green leaves, ensuring the head stays intact without breaking apart.
3. I give the whole head a quick rinse under cold water and pat it thoroughly dry with paper towels.

Par-Boil the Cauliflower

1. I place the whole, trimmed cauliflower head in a large pot where it fits comfortably.
2. I pour in enough vegetable or chicken stock to cover the cauliflower (about 4 cups, maybe more or less depending on size).
3. I add the fresh thyme sprigs and the bay leaf to the stock.
4. I bring the stock to a boil over medium-high heat, then reduce the heat to maintain a gentle simmer.
5. I simmer the cauliflower for about 12 minutes. This par-boiling step helps ensure the inside becomes tender.

Roast and Baste

1. Carefully, using tongs or large slotted spoons, I drain the cauliflower well and transfer the whole head to a cast-iron skillet or any oven-proof pan or baking dish.
2. I ladle a little (maybe ¼ cup) of the flavorful cooking stock over the cauliflower in the skillet.
3. Then, I drizzle the melted butter generously all over the top of the cauliflower head.
4. I sprinkle it with fresh thyme leaves (plucked from the sprigs, if desired) and fresh cracked black pepper (and salt, if needed, considering the stock's saltiness).
5. I place the skillet in the preheated oven and roast for 10-15 minutes, depending on the size of my cauliflower, until it's beautifully golden brown on top.
6. During the roasting time, I like to baste the cauliflower with the buttery cooking juices from the bottom of the pan a couple of times. This adds flavor and helps with browning.
7. I check for doneness by inserting a knife into the thickest part of the core - if it slides in easily, then it's cooked.
8. Optional: If I want a bit more color on top, I turn on the broiler for an extra 2 minutes at the very end, but I watch it very closely so it doesn't burn!

Serve

1. Remove from oven
2. Garnish
3. Slice and Serve

Tips and Tricks for the BEST Roasted Cauliflower

Here are my secrets for making perfect Whole Roasted Cauliflower:

• Trim Carefully: Remove leaves and the tough bottom stem, but keep the core intact so the head doesn't fall apart.
• Par-Boiling: Don't skip the initial simmering in broth! It ensures the dense cauliflower cooks through evenly and infuses it with flavor.
• Basting: Basting with the buttery pan juices during roasting adds flavor and helps achieve a nice golden color.
• Use a Meat Thermometer (Optional): For ultimate precision, the internal temperature near the core should be around 200-210°F (93-99°C) when fully tender.
• Cast Iron Skillet: While not required, roasting in a cast-iron skillet helps create a beautifully browned bottom.

How to Serve

This Whole Roasted Cauliflower is a showstopper! Serve it warm:

• As a Centerpiece: Carve it into wedges at the table like a roast.
• As a Side Dish: Serve wedges alongside roasted chicken, fish, steak, or lamb.
• Vegetarian Main: Serve larger wedges as a main course, perhaps over quinoa or lentils, drizzled generously with the pan juices.
• With Sauce: Drizzle with the buttery cooking juices from the pan. It's also delicious with pesto, chimichurri, or a tahini sauce.

Garnish with extra fresh thyme leaves before serving.

Make Ahead and Storage

• Make Ahead: You can par-boil the cauliflower up to a day ahead. Cool completely, store covered in the refrigerator. Proceed with the roasting step just before serving (it might need a few extra minutes in the oven).
• Storage: Store leftover roasted cauliflower in an airtight container in the refrigerator for up to 3 days.  
• Reheating: Reheat slices gently in the oven at 350°F (175°C) or in an air fryer until warmed through. Microwaving can make it slightly softer.

FAQs about Whole Roasted Cauliflower

• Can I skip the par-boiling step?
  • You can, but roasting from raw will take significantly longer (likely over an hour), and the outside might brown too much before the inside is fully tender. Par-boiling ensures even cooking.
• What other seasonings can I use?
  • Get creative! Smoked paprika, garlic powder, onion powder, cumin, coriander, or curry powder would all be delicious additions sprinkled on before roasting.
• Can I make this vegan?
  • Yes! Use vegetable broth and substitute the butter with a good quality olive oil or vegan butter for basting.

Enjoy this impressive, flavorful, and surprisingly easy Whole Roasted Cauliflower With Butter Sauce! It's a fantastic way to elevate a simple vegetable.
