Crunchy low calorie vegetable, high in fiber and vitamin C, some protein too.
Olive oil is healthy fat, helps absorb vitamins and gives silky richness.
Lemon brings bright tang, its juice wakes flavors and adds vitamin C.
Garlic gives savory punch, it’s aromatic and has allicin for immune help.
Smoked paprika gives smoky warmth and mild heat, colors the roast nicely.
Parmesan: salty umami kick, adds protein and calcium, don’t overdo it though.
Parsley freshens things up, little bitter, lots of vitamin K and color.
Cumin lends earthy, slightly citrusy depth, use small amounts for balance.
Broth adds steam and moisture, helps keep cauliflower tender and flavorful.

Ingredient Quantities

1 large head cauliflower (about 2 to 2.5 lb), core intact, outer leaves removed

3 tbsp extra virgin olive oil (or neutral oil like canola)

1 1/2 tsp kosher salt

1/2 tsp freshly ground black pepper

1 tsp garlic powder (or about 2 cloves garlic, minced if you prefer)

1 tsp smoked paprika

1/2 tsp ground cumin (optional)

1 lemon, zested and juiced (about 1 tbsp juice)

1/4 tsp red pepper flakes (optional)

How to Make this

1. Preheat oven to 400°F (200°C). This only takes a minute or two, and the whole prep should be about 5 minutes anyway.

2. Remove outer leaves from the cauliflower but keep the core intact so it holds together. Trim the stem so it sits flat, you can cut a tiny X into the bottom of the core if it seems lopsided.

3. In a small bowl whisk together 3 tbsp olive oil, 1 1/2 tsp kosher salt, 1/2 tsp black pepper, 1 tsp garlic powder (or your 2 minced garlic cloves), 1 tsp smoked paprika, and 1/2 tsp ground cumin if using. Add the lemon zest and about half the lemon juice to this mix.

4. Pat the cauliflower dry, then rub the oil-spice mix all over the head, getting into crevices as best you can. Use your hands, even if it gets a little messy.

5. Put the cauliflower stem-side down in a small roasting pan or ovenproof skillet. Pour 1/2 cup vegetable or chicken broth into the pan around (not over) the cauliflower to keep the bottom from drying and to add flavor. Sprinkle 1/4 tsp red pepper flakes around if you want heat.

6. Cover tightly with foil or a lid and roast for about 30 to 35 minutes. This steams it so the center gets tender without burning the outside.

7. Remove the foil, spoon some pan juices over the cauliflower, then roast uncovered another 15 to 25 minutes until a knife goes easily into the center and the outside is golden and a little charred in spots. If using Parmesan, sprinkle 1/4 cup grated cheese over during the last 5 minutes so it melts and browns.

8. Once done, squeeze the rest of the lemon juice over the cauliflower, sprinkle 2 tbsp chopped parsley and a bit more salt or pepper if needed. Let it rest 5 minutes so it firms up and the juices settle.

9. Slice into wedges to serve, spoon pan juices over each piece, and enjoy. It looks fancy but was stupidly easy.

Equipment Needed

1. Oven set to 400°F
2. Small roasting pan or ovenproof skillet big enough for a whole cauliflower
3. Aluminum foil or a tight fitting lid
4. Small bowl and a whisk or fork for the oil spice mix
5. Measuring spoons and a 1/2 cup measure
6. Chef knife and cutting board to trim the stem and zest the lemon
7. Large spoon or silicone brush for basting and spooning pan juices
8. Oven mitts and a serving knife or spatula to slice and plate

FAQ

Q: How long and at what temperature should I roast the whole cauliflower? A: Roast at 400°F (200°C) for about 45 to 60 minutes for a 2 to 2.5 lb head. Check with a knife or skewer in the center – it should slide in easily. If the outside browns too fast, loosely tent with foil for part of the time.

Q: The center looks underdone while the outside is browned, how do I fix that? A: Try one of these – steam or parboil the whole head 5 to 7 minutes before roasting, roast stem-side down so heat reaches the core, or add 1/2 cup broth to the roasting pan and cover for the first 30 minutes to help steam it through. Also you can cut a small X in the base of the core to let heat penetrate.

Q: Can I make this recipe vegan or dairy free? A: Yes. Skip the Parmesan and use nutritional yeast, toasted breadcrumbs, or a drizzle of tahini for savory richness. Use vegetable broth instead of chicken broth and you’re good to go.

Q: How do I get a crispier, more caramelized exterior? A: Make sure the cauliflower is very dry before oiling, use a high oven temp (425°F) for the first 10 to 15 minutes or finish under the broiler for 2 to 3 minutes, and sprinkle Parmesan or panko in the last 5 to 10 minutes. Don’t overcrowd the pan, and baste once or twice during roasting.

Q: How do I store and reheat leftovers? A: Refrigerate in an airtight container up to 3 to 4 days. Reheat in a 350°F oven for 12 to 20 minutes or in an air fryer 8 to 12 minutes to get some of the crisp back. Microwaving works but it gets softer.

Q: Can I use a slow cooker or Instant Pot instead of the oven? A: You can steam a whole head in the Instant Pot 10 to 12 minutes on high pressure then flash under the broiler to brown. Slow cookers will make it very soft and not browned, so not ideal if you want that roasted crust.

Whole Roasted Cauliflower Recipe Substitutions and Variations

3 tbsp extra virgin olive oil — swap for avocado oil or grapeseed oil 1:1 for neutral high-heat cooking, or melted butter/ghee for a richer, nuttier finish (use same amount).
1 tsp garlic powder — use about 2 cloves fresh garlic, minced (more pungent) or 1 tsp garlic paste; if using fresh, rub it into the cauliflower or mix with the oil.
1 tsp smoked paprika — substitute sweet/regular paprika 1:1, or use 1/2 tsp chipotle powder for smokiness and heat; cayenne works too but use much less.
1/4 cup grated Parmesan — swap with nutritional yeast for a vegan “cheesy” vibe (same volume), or use Pecorino Romano if you want sharper, saltier flavor; panko breadcrumbs add crunch if you prefer texture.

Pro Tips

– Let it warm up a bit before it goes in the oven. Cold cauliflower takes longer to cook through, so pull it out of the fridge 20 to 30 minutes first, and score the bottom just a little so it sits flat and heat can get into the core easier.

– If you want more golden crust, use a preheated cast-iron or heavy skillet so the outside sears the moment it hits the pan, and cut back on the liquid to a few tablespoons. Or, for quick extra char, pop it under the broiler for 2 to 4 minutes at the very end but dont walk away, it goes from perfect to burned fast.

– For even doneness skip guesswork: stick a long skewer or probe thermometer into the center. When it slides in with only mild resistance the inside is tender. If you want a crunchy topping, mix panko with the Parmesan and press it on the surface in the last few minutes so it browns without getting soggy.

– Dont toss the leaves and core trims. Roast them on a sheet tray for snacks, or blend them into soups, sauces or a quick chimichurri. And leftovers reheat best in a hot oven or toaster oven so they keep some texture, not in the microwave which makes them limp.
