Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 large cauliflower, leaves removed and stem trimmed
3 to 4 tablespoons olive oil
3 cloves garlic, finely minced
½ teaspoon ground cumin
½ teaspoon onion powder
1 teaspoon paprika (smoked or sweet)
½ teaspoon chili flakes (optional)
Salt, to taste
Black pepper, to taste
¼ cup grated Parmesan cheese or nutritional yeast (optional)
Fresh parsley or mixed fresh herbs, finely chopped, for garnish
Lemon wedges, for serving
Directions
Preheat the oven to 400°F (200°C).
Bring a large pot of well-salted water to a boil. Carefully add the whole cauliflower and parboil for 8 to 10 minutes, until just tender when pierced with a knife.
Remove the cauliflower from the water, drain thoroughly, and pat completely dry with paper towels.
In a small bowl, combine olive oil, minced garlic, paprika, cumin, onion powder, chili flakes, salt, and black pepper. Mix well.
Place the cauliflower on a baking sheet or oven-safe dish. Brush the seasoned oil generously over the entire surface, making sure to coat the crevices.
Roast uncovered for 35 to 45 minutes, basting once or twice with pan juices, until the outside is deeply golden and crisp.
Sprinkle Parmesan cheese or nutritional yeast over the cauliflower if using, and return to the oven for an additional 5 minutes.
Remove from the oven, garnish with fresh herbs, and serve hot with lemon wedges on the side.

FAQs
Can I skip the parboiling step?
Parboiling helps ensure the cauliflower becomes tender inside before the outside browns. Skipping it may result in a raw center.
How do I know when the cauliflower is done?
The cauliflower should be easily pierced with a knife and deeply golden on the outside.
Can I use frozen cauliflower?
Frozen whole cauliflower is not recommended for this recipe, as it releases too much moisture and won’t roast properly.
Is this recipe vegan?
It is vegan if you use nutritional yeast instead of Parmesan cheese.
Can I make this ahead of time?
You can parboil and season the cauliflower up to one day ahead, then roast just before serving.
What can I serve with whole roasted cauliflower?
It pairs well with rice, quinoa, roasted potatoes, salads, or flatbread.
Can I air-fry this recipe?
Due to the size of a whole cauliflower, air frying is only possible if your air fryer is large enough. Cooking times may vary.
How can I make it extra crispy?
Make sure the cauliflower is completely dry before roasting and baste lightly to avoid excess oil pooling.
Can I cut the cauliflower into pieces instead?
Yes, but roasting times will be shorter, around 25 to 30 minutes.
Is this good as a main dish?
Yes, it works beautifully as a vegetarian main dish, especially when served with grains or sauces.
