I make roasted cauliflower almost every week. It’s SO simple, it’s healthy, and it’s absolutely delicious. The florets come out of the oven with crisp, golden brown edges and a rich, nutty flavor. They’re perfect for serving as a side dish, tossing into a salad, a grain bowl, or a pasta…or eating straight off the baking sheet.

You’ll find my go-to roasted cauliflower recipe below, along with my best tips and tricks for cooking it perfectly every time. I’ve also shared a few of my favorite ways to serve roasted cauliflower. Yes, this roasted veggie is great on its own, but with a little lemon zest, fresh herbs, or a sprinkle of Parmesan cheese, it’s even better.

How to Roast Cauliflower

To make this roasted cauliflower recipe, you’ll just need 4 ingredients: olive oil, salt, pepper, and a head of cauliflower.

  • Start by preheating the oven to 425°F. Don’t go any lower with the oven temperature here – a hot oven helps the florets crisp up and caramelize as they cook.
  • Then, break the cauliflower into bite-sized florets. I like to break mine with my hands rather than cutting it with a knife. This way, I get prettier florets!

 

  • Next, season the cauliflower. Toss the cauliflower florets with plenty of olive oil, salt, and pepper. Don’t skimp on them! A generous drizzle of olive oil and a big pinch of salt are crucial for making really flavorful roasted cauliflower.

  • Then, bake! Spread the florets in an even layer on a parchment-lined rimmed baking sheet, leaving a little space around each one. Roast for 25 to 35 minutes, or until the florets are tender and browned around the edges.
  • Finally, season to taste with salt and pepper. Enjoy the roasted cauliflower straight off the sheet pan, serve it as a side dish, or add it to salads, grain bowls, pastas, and more.

Roasted Cauliflower Recipe Tips

  • Use convection bake if you have it. If your oven has a convection setting, now’s the time to use it! Similar to an air fryer, a convection oven circulates air constantly. This helps the cauliflower brown beautifully and cook quickly. In a convection oven, it could be ready in as little as 20 minutes, so start checking it early!
  • Leave some space between the florets. If they’re too crowded, they’ll steam and soften in the oven instead of getting brown and crisp around the edges. If you need more space, use two baking sheets.
  • Break the florets into similar sizes. That way, they’ll cook evenly. You don’t want to small florets to burn before bigger ones are tender!
  • Don’t toss the core and greens. Waste not, want not, right? Chop the core into bite-sized pieces and roast them along with the florets, turn them into cauliflower rice, or boil and blend them into a creamy sauce or soup! If your cauliflower has good greens attached, you can cook those too. Toss them with olive oil, salt, and pepper, and roast them on a separate baking sheet until the leaves are lightly browned and crisp.

Roasted Cauliflower Serving Suggestions

Lightly crisp and browned around the edges, oven roasted cauliflower is a fantastic addition to salads, pastas, tacos, and grain bowls. It’s also a delicious side dish on its own! Serve it simply, with sea salt and black pepper, or try one of these variations for a fun twist:

  • Toss it with lemon zest and fresh herbs such as chopped parsley, fresh thyme, or minced rosemary.
  • In the last few minutes of baking, remove the cauliflower from the oven and sprinkle it with grated Parmesan and minced garlic. Bake for about 2 minutes more, until the cauliflower is crisp and the cheese is melted.
  • Sprinkle the baked florets generously with vegan Parmesan.
  • Spice it up! When the cauliflower has just come out of the oven, toss it with your favorite spices while it’s still warm. I like mine with chili powder, curry powder, or za’atar.
  • Or add a sauce. Drizzle the roasted cauliflower with pesto, romesco sauce, tahini sauce, chipotle honey vinaigrette, or chipotle ranch dressing. Regular chipotle sauce would be great too!

    Do you wash the cauliflower? Or you just break it into Florets and put it in the oven? Thanks 😊

    Can I prep this for salads before hand or will the cauliflower go soggy?

    Have loved the ‘humble’ cauliflower since childhood but am only now, on ‘the other side’ coming to relish it baked ! Your lesson is welcome add. yes – garlic and herbs do come into the equation – loved the post . . .

  5. Do you have any suggestions for a substitute to the oil

      Hi Bella, I like to roast veggies with a bit of olive oil, even a small drizzle will do.

    I am amazed by what roasting does to cruciferous vegetables. I like cauliflower, but I especially like it roasted. The best way I’ve ever had Brussels sprouts is roasted, and that is now the only way I cook them. Yum! Broccoli also roasts up well.
