Romanesco is a stunning chartreuse-spired cruciferous veggie in the same family as broccoli and cauliflower. Here we’ve roasted it with shallots, garlic and lemon zest and served with Italian Salsa Verde and Calabrian Chilies.

What is Romaneso?

Think of Romanesco as the handsome Italian cousin of broccoli and cauliflower. Originating in the 1500s, near Rome as the name suggests, it’s a hybrid of cauliflower and broccoli and a stunning display of fractual design.

But please don’t be intimidated by Romanesco’s good looks or fame- it loves to be treated simply like you would broccoli or cauliflower.

And most importantly, do not think for an instant that you are not worthy of this beauty- or couldn’t do it justice (my attitude for years).

It just wants to be experienced.

Today we’ve roasted it in a hot oven until tender-crisp, preserving its beautiful chartreuse hue along with slivers of garlic and shallots and Italian Salsa Verde.

Serving it with a sauce allows you to customize the flavor profile pairing it with what you are already making. Here we are featuring Italian Salsa Verde and Calabrian Chilies. But you can take this in many directions- see embellishments below!

Ingredient Notes

  • Romanesco – Typically chartreuse in color, but purple and orange varieties can also be found. Try to seek out ones will similar-sized spires- for even cooking. Use all parts of the Romanesco- leaves and stems.
  • Shallot and Garlic– Fresh sliced garlic and shallots enhance Romanesco’s flavor.
  • Seasonings– salt, pepper, chili flakes.
  • Optional additions: lemon zest, parmesan, depending on your flavor profile.
  • A tasty Sauce: Gremolata, Italian Salsa Verde, Green Tahini Sauce, Szechuan Sauce, Zhoug Yogurt

Expert Tips

  • Don’t toss the leaves or stem! Romanesco can be pricey- try to use every part of the veggie- stem, leaves and all- see process photos.
  • Don’t cut the florets– pull them apart with your fingers, to preserve their symmetry. Plus this is the fun part.
  • Don’t overcook. Lightly steam, roast or saute- to preserve Romanesco’s vibrant color!

How to Prepare Romanesco

Prepping romanesco.
Start by removing the leaves & stems and trimming off any discolored edges. Slice the leaves and stems in half lengthwise.
Prepping romanesco, pulling off the spires.
Gently pull the buds or spires off the stem, using your fingers rather than using a knife. This will preserve their shape.

ROMANSECO FAQS

Is Romanesco healthy?

Yes! Romanesco is related to broccoli and cauliflower and contains similar health benefits to cruciferous veggies. Cruciferous vegetables contain sulforaphane a compound that supports our liver, prevents DNA damage, and prevents cancer and/or its spread. It protects the brain, reduces allergies, inflammation and helps manage diabetes. Rich in fiber, Romaneso is considered a prebiotic and feeds our healthy gut bacteria.

What is the difference between Romanesco and Cauliflower?

They are similar in nutrients and flavor but are very different in appearance. Cauliflower is white with rounded florets; Romanesco is chartreuse with pointed fractual spires.

How do you eat Romanesco?

Romanesco can be eaten raw, roasted, steamed, fried, or sauteed.

What is the best way to cook Romanesco?

Because Romanesco is so uniquely colorful- cook it in a way that highlights and preserves its vibrant color. Lightly steam it until bright green, roast it on high heat until tender-crisp, or saute it lightly. My favorite way is to roast it.

Can you eat Romanseco raw?

Yes, like broccoli and cauliflower, raw Romanesco is actually good for the gut- a healthy prebiotic that feeds our good bacteria. It is also high in fiber.

Can you roast Romanesco whole?

Yes, though I would caution to par-steam it first until just tender and bright green, drizzle with olive oil and season, and then roast it. Steaming it first will help preserve its color.

Description

Roasted Romanesco!  Romanesco is a stunning chartreuse-spired cruciferous hybrid of broccoli and cauliflower. Roast it with shallots, garlic & lemon- a simple recipe that takes 15 mins of hands-on time! 


Ingredients

Units Scale
  • 1 head Romanesco- choose one that has similar-sized spires for most even cooking.
  • 1-2 tablespoons olive oil
  • 46 fat garlic cloves, each sliced into 45 slices lengthwise.
  • 2 Shallots- cut into 1/2 inch wedges.
  • 12 tablespoons lemon zest- from one small lemon (optional, leave out if adding Asian flavors)
  • 1/2 teaspoon chili flakes, more to taste (Aleppo or Urfa Biber is nice here)
  • 1/2 teaspoon salt, more to taste
  • 1/2 teaspoon pepper, more to taste
  • optional- 1/4 cup shredded parmesan

Italia Salsa Verde (Optional- or see other sauces in post) 

  • 1 cup Italian parsley (packed, tender stems ok) feel free to sub part basil
  • 2 garlic cloves
  • 2 tablespoons lemon juice
  • 2 tsp lemon zest
  • 2 tablespoons capers
  • 1 tablespoon caper “juice” from the jar
  • 12 anchovies (optional)
  • 1/31/2 cup olive oil
  • 1/4 teaspoon salt and pepper, or to taste

Instructions

  1. Preheat oven to 425F
  2. Prep Romanesco: Remove the leaves and stems off the Romanesco, and trim off any discolored ends. Slice the leaves in half lengthwise to create strips. Cut the stem in half, then in 1/4-1/2 inch thick strips. Carefully, starting from the bottom of the bud, pull off the spires with your fingers, keeping them intact.
  3. Season: Place all in a big bowl. Drizzle with olive oil, add the sliced garlic, shallots, zest, salt, pepper and chili flakes and toass to coat well.
  4. Bake: Place on a parchment-lined sheet pan, not overlapping.  Bake for 15 minutes, stir in parmesan if using, and bake for 5-10 more minutes, until tender-crisp, yet still vibrant in color. Taste and adjust salt, pepper, and chili flakes- I usually add more of all. 
  5. While it is roasting, make your choice of sauce. 
  6. To make Salsa Verde: Place everything in a food processor and pulse until uniformly chopped and combined. Add more olive oil to loosen it if you like.  (You can also finely mince everything by hand and stir in a small bowl.) 
  7. To serve, place a few tablespoons of Salsa Verde on a large plate or platter, place the roasted romanesco over the top, with tips pointing up and out-along with all the toasty bits. Then add a few more spoonfuls Salsa Verde over and around. For color and heat, Calabrian chilies are a nice and punchy. 

Notes

Leftovers will keep up to 3 days in the fridge- feel free to reheat- in a sauce pan, in the oven or microwave.

  1. LOVE THIS! Have made this following each of my trips to the farmer’s market recently. Used some green sauce I made a batch of àla McFadden … & yes – added capers & anchovies in at the end!

  2. Perfect timing for this recipe. Had a head of romanesco in my CSA box this week and wasn’t sure what to do with it. Used the salsa verde recipe with it and OMG it was all so good. I almost licked my plate when no one was looking!
