Oven Roasted CauliflowerOven Roasted Cauliflower

Making cauliflower is the perfect vegetable if you are looking to go low carb. I love using it as a substitute in certain recipes like swapping with potatoes in my Loaded Cauliflower Mash, or for rice for Cauliflower Fried Rice, and even as a pasta substitute in my Cauliflower Mac and Cheese.

Roasting cauliflower really brings out its’ nutty flavor and I love how it caramelizes the edges. This recipe is so easy to prepare. I just toss it with garlic, lemon juice and olive oil and top it with freshly grated Parmesan cheese and some lemon zest when it comes out of the oven.

I can eat a whole bowl of this for lunch, but I usually make this as a side. You can serve it with steaks, pork chops or chicken. An irresistible side dish, even for people who don’t like cauliflower.

Hope you enjoy!

Roasting cauliflower brings out its nuttiness flavor and caramelizes the edges. This is such an easy way to prepare it, I toss it with garlic, lemon juice and olive oil and top it with freshly grated Parmesan cheese and some lemon zest when it comes out of the oven.


  • 6 1/2 cups uncooked cauliflower florets, about 1 large cut small
  • 3 garlic cloves, chopped
  • 2 tbsp olive oil
  • kosher salt and fresh pepper
  • juice of 1/4 lemon
  • 2 tbsp Parmigiano Reggiano, freshly grated


  • Preheat oven to 450°F.
  • Combine cauliflower, olive oil, lemon juice, garlic, salt and pepper well so all the florets are coated and seasoned.
  • Place in a large shallow roasting pan and place in the center of the oven.
  • Roast for about 25-35 minutes, turning florets occasionally so they are evenly cooked.
  • Remove from oven and top with cheese and some lemon zest and additional salt and pepper if needed.

  1. Best roasted Cauliflower I have ever tried! It’s delicious. I didn’t flip the cauliflower and it caramelized beautifully. So good, it tasted like a protein. I could see putting this on top of a salad instead of chicken or salmon for a change.

  2. Just delicious…..highly recommend

  3. This is one of our all time favorite side dish recipes of yours. Do you think it would be good in the air fryer?

  4. Easy and so delicious! Cant wait to make this again!! Everyone loved it.

  5. How many servings does this make? Thanks!

  6. Way exceeded my expectations! Simple ingredients and easy preparation result in something truly delicious and healthy. This would also be great as an appetizer with an aioli dipping sauce.

  7. I also add some siraracha sauce!

  8. I made it it’s cooking right now as a matter of fact. I broke it up into Flourz. And I also added some fresh brussels sprouts Habs to it little bit of olive oil pepper flakes and garlic salt. I’m cooking it at 400 until it’s golden brown

  9. My family turned their noses up at the sound of this…but one taste quickly changed their minds. Another delicious recipe. I LOVE finding fun recipes that encourage my kids to eat their veggies! Thanks!

  17. I sprinkle cayenne pepper, harissa or garam masala on  the cauliflower. 

  18. Absolutely delicious – Add some sliced onion rings (separated) when cooking is near complete,  sprinkle cashew or walnut pieces over al and warm — This is absolutely THE best — I love to sprinkle with a bit of tabasco too or feta cheese — OhMyGosh it’s delicious whatever you do!!

  19. Had this for dinner tonight. I can attest that even those who do not like cauliflower love this! 

  20. I love cauliflower. Thank you for sharing the recipe

  21. To those who suggest boiling before roasting….NO! Never boil cauliflower- anyway- always steam. Use fresh cauli for roasting, and go easy on the condiments. 😀

  22. I made roasted cauliflower and the chicken picatta from this site for dinner tonight and the combo was awesome

  23. I made cauliflower Alfredo sauce last week. After reading this, I know that I'm going to make the sauce using this method. Yummy! !!

  26. Good stuff!!

  27. I make roasted cauliflower at least once a week. It's a guaranteed way to get veggies into my picky kids!!

  28. Love this! And it works even better when the cauliflower is sliced thin…like chips.

  29. This is simply amazing! I have made it and even my 6 year old LOVES it. Hooray for not having to force feed veggies! She also loves your macaroni and cheese with "leaves" (spinach). Thanks for having such awesome recipes! 🙂

  30. We love it with red pepper flakes. Cooked the same way but sprinkle with pepper flakes before roasting, no cheese or lemon. Yum yum!

  31. yummy!! simple yet delicious 🙂


  32. At first glance I thought it was popcorn! lol…looks delicious and worth a try. Thank you for sharing!

  33. I love, love, love roasted cauliflower, right to the point where it has quite a lot of colour (for that nuttiness). It takes on spices so well, too, e.g. some cumin and coriander seed, yum!

  34. Mmmm you can get far using a little parmesan ^ ^ This sounds amazing 😀 x

  35. Cauliflower might just be my all-time FAVORITE roasted veggie. I've never tried it with the lemon, thanks for another genius idea Gina!

  36. That looks so good! Nothing beats roasted veggies, yum!

  37. I love roasted anything and I'm sure I'll love this! Thanks for the recipe!

    xo Rachel

  38. One of my favourite side dishes! It converts anyone into a cauliflower lover!

  39. Such a great idea!! I never ever buy cauliflower, but this post makes me think that I should 🙂

  40. I love roasting veggies but had never thought of cauliflower!
    I will definitely be giving this a try!

  41. I actually made something similar last night. I added asparagus (chopped to about 2 inch sections). Gave it a bit of color and included another vegetable that roasts well.

  42. Thanks for sharing here with us

  43. Saw the recipe, cooked it, about to try it out now with my grilled tilapia and green salad. I hope it's yummy!!

  44. YUM! You can skip the cheese, it doesn't need it. Toss in more garlic, keep them whole or cut once or twice (not small pieces). Roasted garlic adds a lot of flavor to this dish.

  45. Wow, that was delish!

  46. I making this tonight but threw in some zucchinni with it as well. I'm making it as a side to the rosemary salmon, which is my absolute favorite! I love you, Gina! Marry me!!! (in a totally non-lesbian way). Not that there's anything wrong with lesbians, I'm just not one. lol.

  47. Finally tried this and it was so good I could NOT STOP MUNCHING on it while the rest of dinner finished! One thing I will stipulate is to pay attention to how much cauliflower you're actually getting out of one head. Once my recipe cooked up, I was left with only 2 one-cup servings, which takes this from 3 Points+ to 8 for a cup! Eeek!

  48. I made this with the Grilled chicken with spinach and mozzarella. Yum!

  49. Has anyone eaten cold? Looking for different lunch snack ideas that don't need to be heated.

    • I've eaten this leftover the next day cold and it's so good! Sometimes I actually prefer it that way to when it't hot. 🙂

  50. Make sure to boil the cauliflower first; it makes such a difference. I used a large pot with 1/4 water and salt and boil covered for 4 minutes. This dish is perfect!!

  51. OMG.. This is so Delicioso!! I made it last night with the Cheesy Jalapeno Popper Baked Stuffed Chicken.. Great meals. Thank You

  52. I thought veggies were 0 points on WW? Are the points due to the olice oil and cheese?

  53. This is a great recipe, I have a new one to add into the rotation.

  54. This was SOOOO good. My husband kept commenting on the great taste every bite he took! I may have to go buy some more cauliflower tomorrow! YUM!

  55. When I first looked at the picture, I thought you had breaded it and it immediately made me think of tempura from a Chinese restaurant! I'm going to prepare this either tonight or tomorrow night. Can't wait!

  56. I had a bag of raw cut cauliflower and broccoli, so used that mixture. Both were delicious and it was so easy to prepare especially since I didn't have to cut up a head of cauliflower. Delishhhhh. Served as a side with the chicken rollitini w/ prosciutto and provelone.

  57. Tried this today. Totally scrumptious!!!

  58. Wow! Best cauliflower I have ever had!!!

  59. This was so easy to prepare and even my kids liked it!


  61. Just made this tonight – delicious! Thanks for another awesome recipe!

  62. Can I use just a metal 9 x 13 pan for this or would a cookie sheet work better? I do not own a roasting pan.

  63. I just stumbled upon your website yesterday by looking for roasted cauliflower. I made your recipe last night and I fell in love with it. I am also counting calories and adore the fact that you have both the actual serving size with measurement and calories. Thanks so much for your work I'll be sharing your website with my family.

  64. Have you ever made this with brocolli and cauliflower? I am thinking of trying it that way!

  65. Another yummy way for cauliflower is EEOV, salt, pepper and chopped fresh rosemary. roast until caramelized. I make a whole head and then eat the rest for lunch.

  66. i tried cauliflower with olive oil and a packet of sazon (a portuguese seasoning) and baked it, DELISH. i can't believe i ate CAULIFLOWER and LOVED it..trying this recipe tonight!!

    i'm in love with this website!! thank you!!

  67. This sounds so good. Can you combine it with the roasted broccoli recipe?

  68. you can use any good parmesan or romano.

    I may have to try this with pasta and sausage!!

  69. I roast caulifower, chicken sausage, garlic and a little olive oil and toss with whole wheat pasta… my family devours it!

  70. Absolutely DELICIOUS!

  71. ok what can i substitute if i cant find parmigiano reggiano because its not that readliy available in my area?

  72. Thumbs up! I've tried to roast cauliflower before and it just didn't measure up. The parmesan is the ticket!

  73. Soooooo good! Perfect as it is written. Thank you again for another wonderful recipe 🙂

  74. It's in the oven as we speak! I can't wait – made your sauteed brussells sprouts last week – delish! Thanks for sharing your awesome recipes!

  75. Isn't it wonderful! Especially as the weather cools.

  76. I just made this and WOW is all I can say…thanks so much Gina…I have lost 42# and have a long way to go, but with things like this to eat it is going to make it much more flavorful and enjoyable to get there and stay there. YOU ARE AWESOME!

  77. Let me know the verdict!

  78. well since everyone elses non-vegetable eating husbands loved this recipe, i'm totally trying this on my boyfriend tomorrow. Been looking for a good way to make cauliflower anyways, this looks great!

  79. This is sooo delicious!! I had to stop myself from eating the entire thing!!

  80. I've NEVER been a fan of cauliflower but after reading the above responses (and trying several of your other receipes) I knew I would enjoy it. I made it tonight and this dish was absolutely delicious! It was so simple and easy to make. Thank you so much for creating such wonderfully delicious and healthy meals. I've hooked many a friend to your site!

  81. Thanks for noticing my typo, it's 126.

  82. Another tasty recipe! We loved it!


  83. I'm looking right above the list of ingredients. I see the calories listed twice… Let me copy and paste:
    "Oven Roasted Cauliflower
    Gina's Weight Watcher Recipes
    Servings: 6 • Serving Size: 1 cup • Calories: 94 • Old Po gints: 3 pts • Points+: 3 pts
    Calories: 126 • Fat: 10.5 g • Carbs: 5.9 g • Fiber: 2.5 g • Sugar: 0 • Protein: 2.8 g "
    But it is 126 calories then?

  84. I don't follow, where are you looking that you see 94 calories?

  85. The nutrition facts say it's 94 calories. But on the line below, it says 126… ?

  86. Kirby, just added the nutritional info and I still get 3 points plus per serving. 4 tbsp of heart healthy olive oil may seem like a lot, but for 6 servings it's really not.

  87. Is it really 1/4 cup of olive oil? That much oil is 14 points and if you add in the cheese as well it comes up as 7 pts per serving in the recipe builder. If the oil is 2 Tbsp it would be 2 pts per serving

  88. Try this without the cheese and instead add fresh thyme. This is a favorite in our family.

  89. This was so good!!! I think I just accidentally ate all 6 servings…

  90. You are the best!!!

  91. This recipe is now 3 points per serving.

  92. Absolutely wonderful, I think this is my new favorite!

  93. I just found your webpage and absolutely love your recipes. The photo's are outstanding too.
    Thanks for making cooking and eating FUN again, without the guilt.

  94. Garlic makes everything better 🙂

  95. I made this last night to go with grilled pork chops. It was OK fresh out of the oven. I wasn't really all that blown away with it, but liked it enough to bring it for lunch today. OMGoodness! It was so much better today!! The flavors blended so good. I wonder if I just ate too fast last night because dinner was late and I was simply STARVED by the time we ate. 😉 Regardless, I will be making this again. It's a nice change from the regular boiled or steamed cauliflower. Thanks so much for your website, Gina!!!

  96. Gina…These were AWESOME!! My husband, who is a NOT a veggie eater, couldn't get enough of them!! I also tried this recipe with broccoli and they turned out fantastic too!! I didn't have lemon or the cheese for either time and they still came out amazing!! Thank you so much for yet another amazing recipe!! I also LOVE your cauliflower soup…the 0pt one. It's great!! 🙂 This has totally turned me into eating veggies in a whole new way!! I've lost almost 20lbs following WW and thanks to you it's been easy with your recipes to follow!! Thanks again!!


  98. Great recipe, loved it!!

  99. I know, when I make this, my family who doesn't like cauliflower as much as I do, eat it with no problem. Thanks for your comment!

  100. wow-what a fantstic way to get the other half to eat cauliflower (he will only eat cauliflower cheese, made in a cheese sauce, topped with cheese, and although very yummy, its very bd for my W.W!) it was absolutly delicious, and my toddler loved her ''white trees''! thank you. BTW only just discovered this blog-AMAZING! well done gina, you have done so fantastically well with this, its so hard to find weight watchers recipes with points and pictures too! love it!

  101. This was super easy and really tasty! I am not a big cauliflower lover but this was really good! Thanks for sharing!

  102. Do I boil the cauliflower first to soften it or just roast it raw?

  103. YUMMMM!!!!! I wanted to find a veggie side to go with spaghetti and this definitely hit the spot! Thank you!!

  104. This recipe is simple and delicious. Our family doesn't really eat cauliflower until I began using this recipe. Now a required appetizer for our get togethers.
    Thank you.

  105. This was a great recipe — even my 6 year old ate it!

  106. I love cauliflower, but am finding that just boiled is getting bland. This is a great way to change it up and keep healthy. Another 30 pounds to go.

  107. Roasted is the only way I like cauliflower. I just use spray oil and some s&p. I am definitely going to try your way with garlic & parmesan. Yummers!

  108. Can't wait to try this… would it be okay point wise to substitue Parm Asiago/Romano…? I live in a small town and our supermarket doesn't have the parmigiano reggiano.

  109. Good for anyone following WW or not. Just tried mashed cauliflower, and it was great.

  110. It looks great! I really need to try this. I've oven roasted asparagus, fennel and many other veggies.

  111. This is one of my favorite ways to prepare cauliflower! Even my 7 year old loves it!

  112. What a great side…or even dinner! I could eat just that and be content!

  113. Pinenuts sound great! I also like to add capers sometimes.

  114. I love roasted cauliflower…makes me think of fall. Sometimes I add pinenuts instead of the parmesan.

  115. I really suggest you use fresh, not frozen. But if you must use frozen, I would probably let it thaw before I prepare it and cut the cooking time down a bit.

    • Thaw and remove excess moisture by wrapping in a towel. I have had to use frozen once or twice and found it turns out better for a variety of frozen veggies.

  116. How would you suggest making this with a bag of frozen cauliflower florets?

  117. Oven rosted is my favorite. This is a delicious recipe…thanks
