Whole Roasted Lemon Tahini Cauliflower
November 10, 2015

One of the things I always tell clients about vegan Thanksgiving is that many of the side dishes, including mashed potatoes, green beans, roasted squash and other root veggies, and cranberry sauce, can easily be made vegan. This means that, even if you attend a family gathering that features traditional turkey as a main dish, you’ll probably still have quite a few things to eat–especially if you chat with friends or family about veganizing the sides in advance. Still, it’s nice to have at least one dish that feels like a “main”–something substantial and eye-catching, a centerpiece in its own right.

This whole roasted lemon tahini cauliflower is the best of both worlds. It’s as quick and as easy to prepare as a side dish: really, you just whip up the lemon tahini sauce, baste the cauliflower, and let it roast till tender. But, for a dish that’s so simple to prepare, it’s effortlessly impressive and attention-grabbing. Which means that you can confidently offer it up as a table centerpiece at any gathering.

There are many different approaches to preparing whole roasted cauliflower. Some are as simple as giving the cauliflower head a rub of oil, salt and pepper–even herbs are optional. Other methods are a little more complex; I love Jamie Oliver’s whole roasted cauliflower, for instance.

For this dish, I wanted a super streamlined approach, because let’s face it, preparing for the holidays involves enough details! So, I used as a flavor base a lemon tahini sauce that’s similar to many others I’ve shared in the past: a tried-and-true blend of tahini, garlic, lemon, smoked paprika (which complements cauliflower really nicely), and a touch of harissa powder. You make a lot of it–more than you think you need–but then you use just less than half of it to baste the cauliflower, and the rest for serving. No juggling separate gravies or sauces or toppings for this dish!

As you can see, the cauliflower takes on a beautiful, golden hue as it roasts, and the garlic, lemon, and tahini flavors seep right into the vegetable. You can baste it a few times as it cooks if you like, but I just slathered it in the tahini sauce and let it cook. Because you serve the cauliflower with extra sauce at the end, you can take a hands-off approach while it cooks, trusting that the finished product will be very flavorful.

In preparing this dish, I realized that it’s not just suitable for gatherings or holidays, even though the presentation is a little fancy. It’s also a really simple way to prepare cauliflower–easier in a lot of ways than chopping the cauliflower up ahead of time. And it creates such an incredibly tender vegetable: you can see how easily I sliced into the center, to make serving wedges.

To serve, I’d simply pair your cauliflower wedges with the sauce and–if you want to get festive–a sprinkle of pomegranate seeds or fresh herbs. That’s it. With a dish this arresting, you don’t need a lot of fancy garnish.

One note about the cooking process: you’ll want to pick a medium sized head of cauliflower for it (about 6-7 inches in diameter). If you choose a really huge one, it may take too long to cook, in which case the crust could burn before the vegetable is tender. If you’re serving more than 6 folks, I’d simply recommend doubling the recipe. Also note that you’ll probably have a bit of tahini sauce leftover, which you can easily use as a dip or dressing or sandwich condiment in the days after your feast. Better to have a little extra on hand, trust me, than to run out!

Whole Roasted Lemon Tahini Cauliflower and Sauce

Author - Gena Hamshaw
Prep Time: 10 minutes
Cook Time: 45 minutes
Total Time: 55 minutes
Yields: 6 servings

Ingredients

  • 1 medium head cauliflower 6-7 inches in diameter
  • 1/2 cup tahini
  • 1/2 cup warm water
  • 2 cloves garlic crushed
  • 1/4 cup lemon juice
  • 3/4 teaspoon salt
  • 1/2 teaspoon smoked paprika
  • 1/4 teaspoon harissa powder optional
  • Pomegranate seeds for garnish (optional)
  • Fresh chopped parsley or cilantro for garnish (optional)

Instructions

  • Preheat your oven to 375F. Wash the cauliflower and trim its bottom stem. Pat it very dry.
  • Whisk together the tahini, warm water, garlic, lemon juice, salt, paprika, and harissa, if using. You should end up with about 1 1/3 cups tahini sauce. Put aside about 1/2 cup of the sauce, and use a brush or your hands to baste the cauliflower generously.
  • Line a Dutch oven *or* a baking sheet with foil or parchment. Place the cauliflower on top. If using a Dutch oven, bake the cauliflower, covered, for 25 minutes. Remove lid and bake for another 20 minutes, or until browning and very tender through the center. If using a baking sheet, simply bake for 45-50 minutes, or until tender and browning.
  • Cut cauliflower into six wedges. Serve with all of the remaining tahini sauce (and use any additional leftover for salads or as a dip through the week--it'll keep for about 5 days in an airtight container!). Sprinkle with pomegranate seeds and fresh herbs, if desired.

Notes

Leftover cauliflower will keep in an airtight container in the fridge for up to three days.

One important nutritional note about this recipe: while it makes a fabulous presentation, it’s not super high in protein. So, if you like, pair the cauliflower with a dish that features some legumes, a simple side of grilled tofu or tempeh, or your favorite Tofurkey roast. The nutritionist in me is always focused on dietary macronutrient balance, so I thought it was worth a mention!

And needless to say, there’s no reason to wait for Thanksgiving (or another holiday) to enjoy this tender and healthful dish. Paired with a soup and/or a grain salad, it would make for a wonderful weekend supper.

I hope you’ll enjoy it as much as I do. A very happy Tuesday to you all!

  1. I love this too, but 400 degrees cooks it in about 25 minutes and it’s golden brown. Instead of salt I used 1 Tbs. white miso – YUMMY!

    Cooking time is way off! 1.75 hrs later and it is still not done at 375. Even checked the oven temp on this Wolf oven and now I’m boosting it to 400.

    • I boil my cauliflower head for 10 minutes prior to baking. Cuts the baking process in half and comes out perfectly tender.

  3. Hi Gena, I am a new visitor to your site, but after making this I will definitely return again. I LOVE this cauliflower; I could bathe in your lemon tahini dressing. Thank you for this deliciousness!!!

    I made this last night and it came out pretty good but I probably should have let it cook longer than 45 minutes. I was really hungry though, haha! The flavors were excellent, I had it with a green salad and crusty bread. I’m already thinking about trying it again but with a miso based sauce.

  5. Looks like a great version! I’ve made a few variations of whole roasted cauliflower and i was most successful with the recipe from bon appetite where the whole cauliflower is first boiled partially (which makes sure the inside isn’t raw) and then baked on a high heat in the oven for a shorter period of time.

  6. what a lovely looking dish:) I love roasted cauliflower, but usually use simply oil, herbs and seasoning – but I’m going to try this, maybe for Christmas dinner, with spicy polenta as a base to sit it on. Thanks for the idea:)

  7. oh gena you’ve stopped me in my tracks – what an awesome method for cauliflower. i just adore how the flavors seep in while cooking – it looks so inviting. the spices here are some of my favorites. beautiful and festive!

    Made this tonight, amazing!! Super easy to whip up dressing in a blender and the taste is just astounding. Glad I have left overs. Even the hubby ate the cauliflower! Roasted with a bit of dressing but served with dressing drizzled on top. Would be great on anything!

    • This is such great news, Mikelle! I’m thrilled it turned out so well. I had a bunch of leftovers, too, and I actually ended up pulling apart some of the cauliflower and serving it in soft tacos, along with black beans — delicious.

  9. Gena, this is such a beautiful, brilliant main dish! I have been trying to plan a perfect Thanksgiving menu and I’m definitely adding this! Thank you 🙂 🙂

  10. Gena, what a wonderful treatment for whole roasted cauliflower! Thanksgiving or not, I would enjoy this any day of the week.I I like your tip about choosing a medium sized cauliflower–I once chose a large one and had the kind of problem you describe. And I agree it wouldn’t be a problem to have this wonderful sauce left over–it’s a version of my favorite salad dressing! Thanks!! xoxo
