1. Prep the Cauliflower Head

The first thing to know about how do you roast a whole cauliflower is that prep matters more than you’d think.

Then slice off the bottom of the stem so the head sits flat on your baking sheet or in a cast-iron skillet.
 
Give the whole thing a good rinse and pat it completely dry, because any leftover water will steam the cauliflower instead of roasting it.
 
This drying step is a small detail that makes a big difference when you’re learning how do you roast a whole cauliflower.
 

2. Oil and Season the Whole Head

Next in how do you roast a whole cauliflower is coating it generously with oil.
 
Olive oil works great, but avocado oil holds up even better at high heat.
 
Rub the oil all over the cauliflower with your hands, getting into the crevices so every part roasts evenly.
 
Then season it well with salt, black pepper, and any spices you love.
 
For a classic flavor, garlic powder and smoked paprika are excellent choices.
 
If you want a Mediterranean twist, cumin with a squeeze of lemon at the end is fantastic.
 
The key when you roast a whole cauliflower is to season boldly, because the inside is mild and needs that punch of flavor.
 

3. Roast at the Right Temperature

A big part of how do you roast a whole cauliflower is getting the oven temperature just right.
 
Preheat your oven to 400°F (200°C) and place the cauliflower on a lined baking sheet or in a heavy skillet.
 
Roast it for about 45 to 60 minutes, depending on the size of the head.
 
Cover it loosely with foil for the first 30 minutes so the inside steams and cooks through, then remove the foil so the outside browns and caramelizes.
 
You’ll know it’s done when a knife slides easily into the center with no resistance.
 
That contrast, a deep golden crust outside and a buttery, tender interior, is exactly what you’re after when you roast a whole cauliflower.
