Garlic Parmesan Roasted Cauliflower

Garlic parmesan roasted cauliflower is the easy weeknight side dish I make when the main course needs a vegetable that takes no attention. Cauliflower florets roast on one sheet pan with olive oil, garlic, and paprika until tender with golden, caramelized edges, then get a layer of melted Parmesan cheese for the last 15 minutes. There is no breading and no extra pan, and it’s ready in 40 minutes.

Key Ingredients

All ingredients and their amounts are listed in the recipe card at the bottom of this post.

Cauliflower: One large whole head of cauliflower, cut into florets about 1 to 2 inches wide, gives you roughly 6 to 8 cups. Readers have told me that bigger florets needed up to 15 extra minutes, so I recommend cutting them evenly so everything finishes at the same time. If you want to save time, feel free to use pre-cut cauliflower florets too.

Paprika: Regular sweet paprika gives the florets color and a mild warmth. Readers have told me smoked paprika works well too, and one reader used an Italian seasoning blend when she ran out of paprika.

Parmesan Cheese: I recommend freshly grated Parmesan from a wedge, grated with the small holes of a box grater. It melts into a thin layer on the florets, while dry, coarse pregrated cheese tends to slide off onto the pan.

Pro Tip: Grate the cheese just before you sprinkle it on. A fine, fluffy pile melts faster and clings better than a packed one.

How to Make Roasted Cauliflower Recipe

Preheat the oven to 400ºF (204ºC) and line a baking sheet with parchment paper or foil.

1. Dry the florets. Make sure the cauliflower is fully dry after washing. Any water left on the florets turns to steam in the oven, and steam is what stops them from browning.

2. Season in a bowl. Add the florets, extra virgin olive oil, salt, pepper, garlic, and paprika to a large bowl and toss well. I season in the bowl instead of on the pan so every floret is coated evenly and the garlic doesn’t pool in one spot.

2. Roast for 15 minutes. Spread the florets on the prepared pan in a single layer. Crowded florets trap steam and turn soft instead of golden, so use two pans if you need to.

3. Flip and add the Parmesan. Turn the florets over, sprinkle with the Parmesan, and roast 15 more minutes. Flipping browns the second side, and adding the cheese now lets it melt without overbrowning.

4. Check and serve. The cauliflower is done when a fork slides in easily and the edges are golden. Garnish with parsley and serve hot.

Olivia’s Recipe Tips

Scrape the toasted cheese back on. Any Parmesan that slides onto the pan browns into crisp little bits. Scoop them up with a spatula and sprinkle them over the florets before serving.

Fix a dry batch with a finish. One reader found hers a little dry and drizzled on melted butter. A drizzle of olive oil, a squeeze of lemon juice and some lemon zest after roasting works too, and other readers have added lemon pepper for brightness.

Turn it into dinner. One reader tossed hers with brown rice and white beans, and I loved that idea. It makes a filling meatless meal.

Steam first for softer florets. A reader whose kids don’t like firm cauliflower steamed it briefly before seasoning. She said it shortened the oven time and meant no flipping halfway.

Frozen cauliflower is untested. I haven’t made this with frozen florets, so I can’t promise the result. Frozen cauliflower releases a lot of water, which works against roasting.
