Whole roasted cauliflower is a sight to behold and never fails to delight, especially when it’s topped with a verdant blend of herbs and pistachios. This version delivers a browned cauliflower that ends up soft enough — custardy almost — to serve with a spoon. And it all comes together in one pan, with water added right to the skillet to steam and soften the cauliflower while it roasts over caramelized onions. Sprinkling some Parmesan on top is a nice way to finish this dish.

Preparation

  1. Step 1

    Make the cauliflower: Position a rack in the center of the oven and heat oven to 400 degrees. Trim the cauliflower, making sure the stem is cut flush with the head so it sits flat. Heat a 10-inch cast-iron or other heavy ovenproof skillet on the stove over medium heat. Add 1 tablespoon oil, the onions and ¼ teaspoon salt and cook, stirring, until translucent and turning golden on the edges, 7 to 10 minutes. Stir in ¾ cup water and remove from the heat.

  2. Step 2

    Rub the cauliflower with the remaining tablespoon oil then with the pepper and remaining ½ teaspoon salt. Clear the center of the skillet and place the cauliflower in it. Cover the pan tightly with foil and place in the center of the oven. Bake until a paring knife meets no resistance when inserted into the cauliflower, 20 to 30 minutes.

  3. Step 3

    Meanwhile, make the pesto: Reserve a bit of lemon zest for garnish. Place the rest in a food processor, along with the herbs, oil, pistachios, garlic, salt and pepper. Pulse until well combined.

  4. Step 4

    Turn oven to 450 degrees on the regular setting or, if you have a convection option, 425 degrees. Uncover the cauliflower and baste with some of the pan juices. Cook, basting occasionally and adding ¼ cup of water to the pan if it threatens to dry out, until nicely browned, 20 to 30 minutes more. Spoon the pesto over top, sprinkle with reserved lemon zest and more herbs, and serve.

Cooking Notes

If you're trying to cut down on your use of foil, the initial cauliflower cooking can be done in a Dutch oven. Works beautifully.

Loved this recipe. Made two adjustments: 1. I used dry white wine to deglaze the pan on the first go, instead of the 3/4 cup water (but I did add in a bit of water during roasting to keep things balanced). Onions turned out super jammy at the center and had crispy caramelized edges. So flipping good. 2. 10 min before finish, I sprinkled finely grated parm on the cauliflower. It made a golden crust and dialed up the flavor. Both have that nutty base and it was just ::chef’s kiss::

Any suggestions to replace pistachios? Pine nuts? Almonds? Allergies to pistachios

This dish turned out great last night with some modifications: 4 Onions instead of 2 as it become a delicious "jam" when done White wine instead of water for cooking (We had a 2.5 pound organic cauliflower from Costco so cooking time was longer) For the pesto: A combination of basil and flat leaf parsley 4 garlic cloves instead of 1 (1 clove for an entire cauliflower, seriously???) Juice of whole lemon

Mona M, you ask what to substitute for the cilantro in the pesto. You could use basil as you suggest. But I think it might work well for this recipe, in particular if being served as part of the Seder menu using the other dishes in the set here, to use a combination of parsley and fresh mint. They play well with the others of pistachios and lemon peel.

I would add a third onion - they sort of melt down to nothing

Yes, this is a very uninteresting pesto recipe, because it leaves out a crucial ingredient: grated parmesan. Add 60 grams of grated parmesan, and make that 2 cloves of garlic, and it will be worth eating. I also agree that 100% flat-leaf/Italian parsley is better than a Cilantro mix.

I halved the cauliflower, cut down total oven time to 30 min, 10 min uncovered. Instead of the pesto I mixed capers, grated garlic, zest and juice of half a lemon, parsley and olive oil. The kids devoured it, we ate the crumbs

Arugula is also a good substitute for cilantro in pesto recipes.

I don’t know why this wasn’t done in a Dutch Oven or heat proof pot. Why fiddle around with aluminum foil? The pesto was very tasty. I used pepper flavored and salted pistachios and he’d off on additional seasoning. The pesto basically made the dish. It took a longtime to achieve the end result of a cooked cauliflower. Overall a bit of a fun experiment in cooking.

1/4 cup each- a total of 1/2 cup

Hi Cheryl- You could sub any nut here- walnuts, almonds, pine nuts would be fine!

Found this to be very good. After reading some reviews, I did add 1/4c parmesan, 2Tbs fresh lemon juice & 1TBS more cilantro & parsley to pesto mixture. Pesto is great and key to making this really good. Not removing thick stalk in center of cauliflower keeps it from getting that desired "custardy" texture unless you up covered cooking time to at least 45 minutes while keeping uncovered time the same. Suggest using pesto on each serving instead of covering whole head. Will increase pesto amount.

This is similar to Julie Moskin's whole roasted cauliflower with almond-herb sauce that is also on this site. I frequently just cut up the cauliflower, add some olive oil and roast it. This is a big time saver, although the presentation might be lacking! I serve the sauce on the side and the sauce typically keeps a few days and is great on other vegetables or a salad.

Deglaze with wine Add more garlic to pesto Add basil and parsley for pesto Add parmesan in the end Add more onion

This recipe is perfect. I made just a few alterations. I subbed the cilantro with sage. I subbed the cauliflower with chicken. I subbed the pistachios with brazil nuts. I subbed ramps for the onions. I encased everything in clay in lieu of aluminum foil and roasted it in my neighbor's fire pit while they were sleeping.

whew - the "orange " ( ? ) cauliflower really blew my mind ... organic

Nicer to look at than eat. Next time I will double the onions and pesto as there's not enough flavor for me in the recipe as written.

I rarely think a recipe in the NYT falls short, but this fell through the floor. By essentially steaming the cauliflower the texture is all but eviscerated by becoming more mush than munch. The additional cooking time with the foil removed does indeed result in a gorgeous browned crown, but beneath that is more mush. As methods go, this isn't a good one. Lose the foil, baste as needed, and you'll have a roasted cauliflower, flavor and crunch intact. And yep, add more onions for that jammy base.

This was a big hit at Passover. I used a dutch oven, added more onions and added some turmeric to the oil before rubbing it on the cauliflower.

This is one of my favorites! So easy and yet such an upgrade from the usual. I love a new way to present vegetables! I used wine vinegar to de glaze, a whole head of garlic, an additional large handful of arugula in the parsley, cilantro pesto to make an adequate dose of greens. So delicious!! Next time I will more than double the onions. They add an amazing dynamic to this dish.

This presentation, while pretty, results in a lot of trapped moisture between the florets. The end product is then kind of soggy. This would be better prepared with texture and moisture in mind: separate florets, toss in oil and salt and roast on a sheet pan. The onions could be cut into large wedges and given the same treatment. Then dollop on the pesto.

Delicious and very easy to make. I think the pesto is fantastic and am confused by the comments describing it as bland. We served as our main dish with rice pilaf on the side and have tons of leftovers (for two people). Looking forward to having more tomorrow!

I made this last night for our Seder. Everyone loved it. Was very confused about the cooking time with all of the comments; however, it was perfect. Will definitely make again.

Loved this idea. My mods were lime juices as well as the zest, and a little rice wine vinegar. It was really good and not as expensive as the traditional pine nut version with basil.

Loved this, but like others felt the pesto needed lemon, then it was phenomenal. Only disappointment was that the outside of the cauliflower was brown but not crispy. Should I have basted less?

The trick is really making sure the cauliflower is soft enough before you turn the heat up. Then it is heaven, and perfect if you’re serving people who require dairy-free and gluten-free food (though there are many variations you can imagine with cheese).

I agree with all the notes, this recipe is delicious with needed tweaks. I liked the basic idea of double the onions, keep adding water and/or use sherry, double or triple the garlic, try basil or all parsley, add Parmesan, use a Dutch oven. I recommend quartering the cauliflower to better remove the slightly bitter which keeps the presentation and reduces the cook time. I recommend reading others notes to get more detail. I’d make it again.

I love the pesto recipe as is. No parm makes it suitable for a meal with meat or chicken, if you keep kosher.

It’s rare I don’t like the recipes I find on the app, but this one was a miss for me. It was just too bland for my taste, the pesto was bitter and lacked « depth ». Maybe parmesan would have helped, but I won’t be making it again to find out.
