Roasted romanesco is a simple way to enjoy this spiky cruciferous vegetable that's a fun cross between cauliflower and broccoli. A simple creamy turmeric tahini sauce is perfect to serve alongside!

I remember when I first discovered romanesco about 8 years ago.

In fact, I even created this crispy curry broccoflower recipe with it, I just happened to call it by its other name. More on that in a bit.

I don’t know if not encountering romanesco until I was 30 is evidence of a pretty sheltered produce life up to that point or, if stores have just gotten that much better about carrying a more wide variety.

Let’s go with the latter for my ego.

But these days, this weird vegetable that looks like a mix between little piles of Christmas trees and the back of a dinosaur is pretty easily found.

And if you’ve never tried it, I highly suggest picking one up!

whole romanesco


Technically, it’s a member of the brassica family. Aka a cruciferous vegetable.

You may know that term more familiarly as cauliflower, broccoli, cabbage, kale and Brussels sprouts to name a few.

Kohlrabi is another and I love this roasted kohlrabi dish equally as much as this romanesco side dish!

While it looks almost exactly like a mix of cauliflower and broccoli, romanesco is its own veggie. Those crazy fractal pattern florets definitely distinguish it as such!

From a flavor perspective, it has a slightly nutty flavor. It’s less bitter than broccoli and a bit “heartier” tasting than cauliflower.

It can be a confusing one to identify as romanesco goes by quite a few names!

You may see it referred to as cauliflower romanesco, Roman cauliflower, broccoli romanesco or, like I called it originally, broccoflower.

There seems to be a bunch of conflicting information as to the accuracy of all those “other” names so it’s best to just go with romanesco and leave it at that!

romanesco cut into florets


Like almost any vegetable, roasting is my favorite way to enjoy romanesco.

Particularly when it comes to cruciferous vegetables, roasting just brings out the best in a vegetable.

It’s also the easiest and least messy cooking method so that’s always a win!

That said, you could also air fry it like this air fryer frozen broccoli recipe using the same approach for a similar crispy outcome.


  1. Preheat oven to 400°F. If you have a convection setting, I always like to use that for roasting all vegetables. If you don’t have a convection setting, I recommend roasting at 425°F.
  2. Break the romanesco into florets and place in a large bowl.
  3. Whisk together avocado oil, minced garlic, juice and zest from the lemon with salt and pepper.
  4. Pour the mixture into the bowl and toss until every floret is coated.
  5. Spread the romanesco out onto a baking sheet.
  6. Roast for 10 minutes, stir/toss and return to the oven for another 10 minutes until crispy and starting to turn golden brown around the edges.
creamy turmeric garlic and lemon tahini sauce to serve with roasted romanesco


While I can happily enjoy a full plate of roasted vegetables all alone, a delicious sauce to drizzle over them or dunk into never hurts!

This creamy turmeric tahini sauce comes together in just minutes and becomes the perfect tasty topper for roasted romanesco.

To make the turmeric tahini sauce you’ll need:

  • creamy tahini (I recommend a good quality tahini like this one)
  • lemon juice
  • extra virgin olive oil
  • maple syrup (or honey)
  • minced garlic
  • ground turmeric
  • ground ginger
  • Kosher salt
  • water

Mix all the ingredients except for the water in a bowl and stir until smooth.

Slowly add the water and whisk or stir together until you reach the desired consistency.

If you want to drizzle the sauce on the roasted romanesco, you may want it a little thinner than if dipping the romanesco into the sauce.

If you love the sound of this tahini sauce, make sure to check out this Blueberry White Bean Salad with Tahini Turmeric Dressing as it’s quite similar!

crispy roasted romanesco

I often don’t blog these simple roasted vegetable recipes because, well, they’re just so simple it almost seems ridiculous to!

But, similar to the baked white acorn squash, roasted brussels sprouts on the stalk and roasted purple sweet potatoes, I seem to be embracing simplicity lately with my recipes.

It’s how we actually eat in my house 90% of the time so it seems to only make sense to share it.

Especially if you’re like me, see fun things (like this romanesco) at the grocery store, buy them and then get home and just google: “fun thing” + recipe.

If that’s you – I hope this roasted romanesco recipe does the trick!

Usually when I’m making roasted vegetables as a side dish for dinner, I keep the rest of the meal simple as well.

Main dishes like this Pistachio Crusted Flank Steak, Simple Skillet Pork Chops or Tart Cherry Glazed Salmon are all good options.

Sheet Pan Piri Piri Chicken and Five Spice Cream Cheese Chicken are great chicken options.

And, if you don’t want to roast the romanesco, you can try this romanesco cauliflower pasta or this romanesco soup instead.

In fact, since I love this creamy broccoli soup and this creamy brussels sprouts soup so much I’m eager to try that romanesco soup soon.

Yield: 4 servings
Prep Time: 5 minutes
Cook Time: 20 minutes
Total Time: 25 minutes

Romanesco is a fun cruciferous vegetable closely related to broccoli and cauliflower. Enjoy it simply roasted with turmeric tahini sauce.


For the Romanesco

  • 1 head romanesco, broken into florets
  • 2 tablespoons avocado oil
  • 1 tablespoon minced garlic
  • zest from half a lemon
  • juice from half a lemon
  • salt and pepper to taste

For the Tahini Sauce

  • 1/4 cup creamy tahini
  • 2 tablespoons lemon juice
  • 1 teaspoon extra virgin olive oil
  • 1 teaspoon maple syrup (or honey)
  • 1/2 teaspoon minced garlic
  • 1/2 teaspoon turmeric
  • 1/4 teaspoon ground ginger
  • 1/4 teaspoon Kosher salt
  • 3 tablespoons water


  1. Preheat oven to 400°F.
  2. Place the romanesco florets in a large bowl.
  3. Whisk together the remaining ingredients for the romanesco in a small bowl then pour into the bowl with the florets. Toss to combine.
  4. Spread out onto a baking sheet in a single layer and roast for 10 minutes. Stir to toss the romanesco on the pan and roast for an additional 10 minutes. You can broil on high for the last 1-2 minutes for extra crispy edges if desired.
  5. While the romanesco roasts, make the tahini sauce by combining all the ingredients except water in a bowl. Whisk until smooth then drizzle the water in slowly while whisking until a sauce-like consistency results. It should be drippable but not too thin. Add or subtract water as necessary for desired result.
  6. Serve the roasted romanesco with the tahini sauce while hot.

I bought a head of romanesco having never heard of it and thinking it was gorgeous and I'd find something delicious to do with it. And so this evening I sat down and searched for recipes. I was lucky enough to have found this one. I'm not one for following recipes to the letter, so I was just looking for ideas and cooking methods/times more than anything.

I didn't have avocado oil or olive oil so I used peanut oil in each part of the recipe. I didn't have lemons, but I had fresh lemon juice, so I just omitted the zest. I couldn't find my ground Ginger, so I found my Fiji Ginger Syrup and used that instead of ground Ginger and maple syrup. I likely put too much turmeric and I decided to use ground sumac berries because I came across them in my search for the ground Ginger. I put the ground sumac berries in both the coating for the romanesco and the tahini sauce. I used very little salt.

Also, I measured none of the ingredients. I just flew by the seat of my pants on all that.

And WOW! It was amazing! This review is for anyone who thinks they have to have all the exact ingredients and all the perfect measurements.

Also, to the author, thank you for giving me the basis on which I could create. It was fantastic. I sat and ate the whole head of romanesco with the tahini sauce as my entire dinner. Delicious!
