Ingredients

Here’s what you’ll need to make perfectly roasted cauliflower:

  • Cauliflower – A medium head, cut into florets. Try to keep the pieces similar in size so they roast evenly.
  • Olive oil – Just enough to coat the florets and help them crisp up.
  • Salt & pepper – The basics! Don’t skip the salt—it brings out the natural sweetness of the cauliflower.
  • Optional extras – Add garlic powder, smoked paprika, or even a pinch of cumin for extra flavor. A sprinkle of Parmesan or nutritional yeast is also delicious once it comes out of the oven.

How to roast cauliflower

Start by preheating your oven to 400ºF (200ºC) and lining a large baking tray with parchment paper.

Prepare the cauliflower: Remove the outer leaves and trim the base. Then cut the cauliflower into florets—slicing where they naturally branch off the core. For even roasting, break up any large florets into smaller, bite-sized pieces.

Season: Spread the florets on the baking sheet and drizzle with olive oil. Add salt, pepper, and any spices you’re using. Toss everything together (or mix with your hands) until well coated.

Roast: Arrange the cauliflower in a single layer , leaving space between pieces so they roast, not steam. Roast for 25–30 minutes , flipping halfway through, until golden with crisp edges and fork-tender centers.

Tip: If your florets are on the smaller side, start checking at around 20 minutes.

Finish and Serve: Once your roasted cauliflower is done, you can squeeze a little lemon juice over the top, sprinkle with parsley or Parmesan, and serve immediately. I love it with a side of tahini sauce , but it also pairs beautifully with grains, salads, or roasted proteins.

Make-Ahead & Storage

  • Make-ahead: Cut the cauliflower into florets up to 3 days in advance and keep them in the fridge until you’re ready to roast.
  • Leftovers: Let the roasted cauliflower cool completely, then store in an airtight container in the fridge for up to 4 days .
  • To reheat: Use the air fryer or oven to crisp it back up. The microwave works too, though the cauliflower will be softer.

It’s also great for meal prep—just add it to bowls, wraps, or lunchboxes as a simple veggie side.

My tips for the best roasted cauliflower

  • Cut florets evenly so they roast at the same time
  • Don’t overcrowd the pan —use two trays if needed to avoid steaming
  • Toss halfway through for even golden edges
  • Cut to create flat sides —more surface contact means more caramelization
  • Use high heat (425ºF / 220ºC) to crisp without drying
