I’m Obsessed With The Crust On This Whole Roasted Cauliflower
Did you know that you can roast a whole cauliflower head without cutting it apart? I love roasted cauliflower florets, but this whole roasted cauliflower feels truly special in a way that florets can’t match. Here’s why:
- It looks impressive, as a main dish or a side – This dish looks special enough to be be a vegetarian main, but personally I often serve it as a side.
- Tender inside with a golden garlic parmesan crust – I usually prefer to roast veggies in smaller pieces for all the caramelized edges, but what roasted whole cauliflower lacks in that department, it makes up for in flavor and texture contrast! The herby garlic parmesan sauce is totally irresistible. And if you’ve made and liked my roasted broccoli and cauliflower, the crust here is similar.
- Quick and easy – A.k.a. the kind of recipe I love making. The prep takes just 10 minutes, with almost no chopping, and no watching it as it cooks! Whole baked cauliflower makes a stunning addition to a special dinner (like Christmas or Thanksgiving), but simple enough to enjoy any night of the week.
In other words, this whole roasted cauliflower recipe can pretty much do it all. Make it with me!
Ingredient & Substitutions
Here I explain the best ingredients for my baked full cauliflower recipe, what each one does, and substitution options. For measurements, see the recipe card.
- Cauliflower – I based the amounts of the other ingredients on a medium whole head of cauliflower. If yours is large, I recommend increasing the amounts of the oil, cheese, and seasonings by 1.5X, and you’ll need to bake it for longer.
- Grated Parmesan Cheese – It crisps up on the whole roasted cauliflower, almost like breadcrumbs. You can try other cheeses, but only parmesan gets this amazing texture. Feel free to mix in some actual breadcrumbs — I’ve done this with gluten-free panko.
- Garlic – I chose crushed garlic rather than minced because it doesn’t burn as easily. You can substitute 1/2 teaspoon garlic powder, but fresh tastes best here.
- Seasonings – I used dried basil, parsley, thyme, sea salt, and black pepper. You can use an equivalent amount of Italian seasoning instead of individual herbs to save time. If you have fresh herbs instead of dried, just triple the amount, as they’re less concentrated.
- Olive Oil – Ghee or avocado oil works, too. I don’t recommend butter here, which will burn.

How To Roast A Whole Cauliflower Head
I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card.
- Prep the cauliflower. Roasting a head of cauliflower whole requires removing the core while leaving the head intact. To do this, remove the outer leaves, then cut off the bottom and remove some of the core, so that it’s flat. My picture below shows what it should look like when done.
- Make the sauce. In a small bowl, stir together the olive oil, garlic, parmesan, herbs, salt, and pepper.
- Season the cauliflower. Place the cauliflower head upside down (core side up) in a Dutch oven (this one is the perfect size). Drizzle half of the sauce over it and let it drip down the core. Turn the cauliflower over and drizzle with the remaining sauce. Use a basting brush to spread it all over.
- Cover and roast in the oven. It’s done when it’s fork tender — I just pierce the roasted cauliflower head with a knife or fork to check.
- Brown the outside. Sprinkle more parmesan cheese on top, then place under the broiler until the cheese is browned. I like to garnish my whole roasted cauliflower with fresh parsley, or sometimes even extra parm.
My Recipe Tips
- Be careful not to cut too far when cutting away the core. You want to remove the woody center, but removing too much can make your whole baked cauliflower fall apart.
- Ensure that the entire head of cauliflower gets coated in sauce. You can use a spoon to help distribute it evenly, but I prefer a silicone brush like this.
- Do you have to use a Dutch oven? No, but it creates the best texture. I have several, and this is my favorite. You can make this recipe in a cast iron skillet or a regular pot instead, but using a skillet would require you to boil the cauliflower first, whereas a pot just doesn’t distribute heat as evenly.
- Make extra sauce if you want some for drizzling. The garlic parmesan sauce soaks into the whole roasted cauliflower, so there isn’t really any extra. If you want more for serving, I recommend making a double batch. My tahini sauce or lemon butter sauce are also amazing drizzled on top.
- Here’s how I serve it: Carefully lift the cauliflower out of the Dutch oven and onto a cutting board or serving platter. I use two large forks and lift from underneath. Then, you can slice it into “steaks” (large circles — see a visual in my cauliflower steaks post) or cut it into thin wedges, kind of like a pie (like I did in the pictures here).
- Leftover ideas: While you can certainly reheat whole roasted cauliflower, I prefer to repurpose the leftovers by blending then into my creamy cauliflower soup, turn them into a cheesy cauliflower casserole, or add them to my roasted vegetable salad.
Whole Roasted Cauliflower
By
My whole roasted cauliflower has an impressive parmesan crust with garlic and herbs, but it's so easy to make, with simple ingredients.
Instructions
[ See step photos See my tips ]Tap on the times in the instructions to start a kitchen timer.
-
Preheat the oven to 400 degrees F (204 degrees C).
-
Rinse the cauliflower head and pat dry. Remove the outer leaves. Carefully cut off the bottom so that it's flat and most of the woody stem is removed, being careful not to cut off so much that it falls apart. Be sure the head stays intact.
-
In a small bowl, make the garlic Parmesan sauce. Stir together the olive oil, minced garlic, 2 tablespoons (28.3 grams) grated Parmesan (half of the total amount), basil, parsley, thyme, sea salt, and black pepper.
-
Place the trimmed cauliflower head upside down (core side up) onto a 6-quart (5.6 liters) dutch oven. Drizzle 1/2 of the sauce over the cauliflower, tilting it to let it drip down the core and all around. Flip over and drizzle the remaining sauce over the top. Use a pastry brush to brush on any that had dripped down to the pan or didn't spread well.
-
Cover the dutch oven with a lid and bake for 35-45 minutes, until the cauliflower is tender and pierces easily with a skewer, knife or fork.
-
Remove the lid. Sprinkle the top of the cauliflower with the remaining 2 tablespoons grated Parmesan cheese. Place the cauliflower under the broiler and broil for about 5 minutes, until the cheese is browned.

Maya’s Recipe Notes
Serving size: 1/4 head of cauliflower
- Tips: Check out my recipe tips above to help you prevent the whole cauliflower head from falling apart, ensure the whole thing is full of flavor, alternatives and recommendations if you don’t have a Dutch oven, how to serve this dish, and my favorite leftover ideas.
- Storage: Store leftovers in an airtight container in the fridge for up to 4 days.
- Meal prep: I like to prep the whole cauliflower head and mix the garlic parmesan sauce in advance, but store them separately.
- Reheat: Cover in foil and bake at 350 degrees F. I recommend adding fresh parmesan on top before reheating. The microwave works in a pinch, but the texture is best with the oven method.
- Freeze: You can freeze the roasted cauliflower head whole, or cut into slices or wedges before freezing. It will keep in the freezer for up to 3 months. Thaw in the fridge overnight before reheating.

Whole Roasted Cauliflower
Serving Ideas
I usually serve whole roasted cauliflower as a main dish, with one of the proteins below. You can pick one of my healthy side dishes or salads to go with it if you prefer to make it your centerpiece.
- Steak – My most popular options are filet mignon (the one I love the most), sirloin steak (the one I make the most), and New York strip (the one I save for company).
- Chicken – Try my baked chicken legs for a simple, flavorful dinner. For a richer main dish, I love Tuscan chicken, creamy mushroom chicken, or chicken Cacciatore — all these sauces are delicious drizzled over the cauliflower, too.
- Pork – Try my baked pork tenderloin for something simple, or stuffed pork chops for comfort food.
- Seafood – My go-to options are baked cod or baked salmon. For special meals or date night, I recommend sea bass, lobster tails, or pan seared halibut.

1Hi, Tried your recipe tonight as I daily cook for my 86 year old Mom, and at times, My daughter. We all really loved this. Even Mom who doesn’t care for cauliflower commented on how good it was! Daughter said it had a Greek Flair. I followed the recipe , but as I like to do early prep,I put the mixture in the fridge, until ready to use…..which made it thick. Added a splash more olive oil and was perfect and did not drip. I used a foil lined small pan and covered it with foil. Was perfect at 35 min.then broiled with extra Parm. Thank you for an easy, great tasting recipe for Cauliflower!
Robin
1We enjoyed this recipe. I remember the first I made it I thought my husband would not enjoy. Surprise surprise he did enjoy more than anyone. He would ask for me to make it. So today I am making it as part of dinner. It is so delicious. Thank you Maya for the delicious recipes and ideas for dinner. God bless you.
Gwen
1I took a chance buying cauliflower, a vegetable my family isn’t used to having. I followed your recipe and it came out great! I cut it in slices (which I’ve never seen done before). There were no leftovers and my family said they loved it.
Denise ward Lee
1If I could give more than 5 stars, I would as this recipe is absolutely delicious, this is going to be done on a regular basis as it’s very impressive.

0I’m glad you liked it, Robin! Thanks for giving it a try!
Lorene
0I did not use cheese as I am allergic to dairy. I used 1 tablespoon dried Italian herb mix. I parboiled cauliflower in 2 quarts + 1/4 cup sea salt for 5 minutes stem down and 3 minutes stem up. Then removed some of the stem after I drained it for 10 minutes. Then, I drizzled the sauce all over the cauliflower and baked it for 45 minutes at 400 degrees F. The addition of the Italian herbs and garlic was a game changer for me because I normally just used pepper…fragrant and delicious. Will make it again. Served with baked halibut.

0This was an easy and delicious way to roast cauliflower. Very flavorful.
Tara Mendoza
0I cooked for 45 minutes at 400°F and it was not fork tender. What happened? How much longer do I cook it?
Maya | Wholesome Yum
0Sorry to hear that, Tara! It might be oven differences or that your cauliflower head was very large. I would keep checking on it every 5-10 minutes until tender.
Rebecca P
0This roasted whole cauliflower is soooo good. I paired it with roast pork. I have leftovers and I honestly look forward to them. Thanks for such a great recipe. I did double the cheese but I love cheese.
Regina
0I love this recipe. The dish can be used in every season ?
Raymond
0I’m so excited about your recipes. So looking to make healthier food choices. Aloha
Maris
0I made this recipe twice! Well because the first one failed because my cauliflower fell apart. But of course, I’m not one to easily give up lol! This time, I followed the tip to be careful when removing the core. The cauliflower turned out perfectly tender on the inside with a golden crust on the outside. And it really looked fancy!
Lisa
0This roasted cauliflower had such a unique texture! The outside was golden and crispy, while the inside was soft and tender. So good!
Jean
0My whole family really enjoyed this recipe. It’s super flavorful and hearty enough to be a good main dish when paired with a salad, or a simple side. I’ve always wanted to try a whole roasted cauliflower dish but have been a little intimidated at how to do it. Your guide was perfect and the seasonings made it delicious.
Gretchen
0I love the flavor of this recipe! This is one of my family’s favorite sides. Who would’ve thought a cauliflower could be so delicious.
Natalie Paladio
0I love a whole roasted cauliflower and this does not disappoint. Super tasty and a cinch to make.
Deena
0Instead of parmesan cheese could I use Nutritional Yeast instead? It looks so delicious and would like to give it a try.
Maya | Wholesome Yum
0Hi Deena, I haven’t tried that, but I think it would work. Let me know how it goes if you try it!
ECS
0This was a delicious recipe. I had a very large cauliflower and needed to add more oil to coat properly but not a problem. I cooked for 35 minutes but I will cut that down to 30 minutes next time, because it was falling apart. Still tasted great!
Donna
0I made this for my son and his family. We all loved it. It is delicious, easy to make and keto. Perfect!
