Cauliflower: Choose a medium-sized head with tight, creamy white florets and minimal browning for even roasting.
Olive oil: Extra virgin works best for drizzling and roasting, providing that rich fruity base flavor.
Turmeric: Adds warmth and a gorgeous golden color—don’t skip it, it’s subtle but important.
Cumin seeds: Toasting these during roasting releases their nutty, fragrant aroma that complements cauliflower wonderfully.
Sea salt: I love flaky Maldon salt for finishing—it adds crunch and a burst of salinity.
Tahini: The star of the sauce, creamy sesame paste adds richness and a slight nuttiness that balances the roasted cauliflower.

Tweak to Your Taste

This recipe is a canvas, so I encourage you to experiment! Whether you’re someone who likes a little heat or someone who adores bright herbs, tuning it to your palate makes it your own. I switch up garnishes and spice levels depending on the mood—and you can too.

Add Heat: I sometimes toss a pinch of chili flakes or a drizzle of harissa in the tahini sauce when I want a little fire—super easy to do and adds a lovely kick.
Make it Vegan & Nut-Free: This recipe is naturally vegan, and you can skip the pistachios or swap with toasted sunflower seeds if nuts are an issue.
Seasonal Twist: Roasting cauliflower with a sprinkle of sumac or za’atar in place of turmeric gives it a slightly different zing that’s perfect for fall or winter dinners.

Step-by-Step: How I Make Roasted Cauliflower with Tahini Sauce Recipe

Step 1: Prep and Blanch the Cauliflower

First off, preheat your oven to 450ºF. Then rinse your cauliflower well and slice a small piece off the bottom of the core so it sits flat and steady. This little trick stops it from wobbling while roasting, which means more even cooking. I also trim away any big leaves covering the sides but leave a few—those roast up crisp and tasty!

Next, bring a pot with about 3 inches of water to boil. Carefully stand the cauliflower head-up in the pot, cover it, and simmer for 8 minutes. This softens the inside and cuts down on roasting time, plus it gives you that lovely tender texture we all want.

Step 2: Dry, Oil, and Spice

Lift the cauliflower from the water carefully with a slotted spoon and place it stem-side down on a parchment-lined baking sheet—ideally on a wire rack so moisture can escape. Let it sit until dry to the touch, about 15 minutes (you can prep it up to a couple hours ahead—bonus!).

Remove the rack, then drizzle 2 tablespoons of olive oil over the cauliflower, rubbing it in to coat all the nooks and crannies. Sprinkle turmeric, sea salt, and cumin seeds evenly over the top, then drizzle a bit more olive oil (but don’t rub this time)—this double-oil step helps with that gorgeous golden-brown roast.

Step 3: Roast to Perfection

Pop the cauliflower in the oven and roast for around 40 to 45 minutes. You’re aiming for tender florets with a little char and deep golden edges. Every oven is different, so keep a close eye—poke with a knife at 40 minutes to check tenderness. That charred flavor really brings the whole dish to life.

Step 4: Whip Up the Tahini Sauce

While the cauliflower roasts, mix up your sauce. In a bowl, combine the tahini, fresh lemon juice, grated garlic, olive oil, and a pinch of kosher salt. Whisk in 1/4 cup of ice-cold water until the sauce is smooth and lighter in color—add more water if you want it thinner. This makes the sauce silky and easy to drizzle, kind of like magic.

Step 5: Serve and Garnish Like a Pro

Let your roasted cauliflower cool a few minutes before transferring it to a pretty platter. Drizzle it generously with your tahini sauce, then sprinkle on chopped fresh mint, parsley, and pistachios for freshness and crunch. Finish with a pinch of flaky salt for bursts of flavor. Serve with extra tahini on the side because you’re going to want more!

Pro Tips for Making Roasted Cauliflower with Tahini Sauce Recipe

Don’t Skip the Blanch: Simmering the cauliflower first ensures it cooks evenly inside and out, avoiding dry or tough sections.
Use a Wire Rack: Roasting the cauliflower on a rack keeps it from steaming in its own juices and helps you get those crispy edges.
Adjust Tahini Sauce Consistency: Add water gradually to get a smooth, pourable sauce—too thick makes drizzling tricky, too thin loses richness.
Watch Your Oven: Oven temps vary so check early to avoid burning, and embrace some char—it’s flavor gold.

How to Serve Roasted Cauliflower with Tahini Sauce Recipe

Garnishes

I’m all about fresh bright garnishes here—fresh mint and parsley add a lovely pop of color and freshness. The pistachios bring a buttery crunch that contrasts beautifully with the creamy tahini. A sprinkle of flaky Maldon salt right before serving is the finishing touch that brings all the flavors alive. If you’ve got pomegranate seeds on hand, they’re a stunning, juicy addition too!

Side Dishes

This roasted cauliflower shines as a showstopper side dish. I love pairing it with a cozy grain like fluffy couscous or herbed quinoa to soak up any extra tahini sauce. It also complements grilled meats or roasted chicken perfectly, and for a full vegetarian meal, serve it alongside a fresh Greek salad or warm flatbreads.

Creative Ways to Present

For a dinner party, I’ve served the whole roasted cauliflower right on a large wooden board surrounded by bowls of tahini sauce and fresh herbs so guests can help themselves. It also looks gorgeous cut into wedges drizzled with extra sauce and sprinkled with seeds and nuts for texture. Fun fact: adding edible flowers on top makes it absolutely Instagram-worthy!

Make Ahead and Storage

Storing Leftovers

Leftovers? No worries. I usually store the cauliflower and tahini sauce separately in airtight containers in the fridge for up to four days. This keeps the cauliflower from getting soggy and the sauce fresh tasting. When it’s time for leftovers, just drizzle the sauce over again right before serving.

Freezing

Freezing roasted cauliflower isn’t my go-to because the texture can get a bit mushy after thawing. But if you want to, make sure to cool it completely, wrap tightly in plastic, then freeze for up to 2 months. Thaw overnight in the fridge and reheat on the stove or in the oven for best results.

Reheating

To reheat, I prefer using a skillet over medium-low heat—it keeps the cauliflower from drying out and helps revive a bit of crispiness. Just add a splash of water to avoid sticking. You can also microwave leftovers gently, but avoid overcooking to keep the tahini sauce from breaking or drying out.

FAQs

Can I make Roasted Cauliflower with Tahini Sauce Recipe gluten-free?

Absolutely! This recipe is naturally gluten-free as it revolves around cauliflower and a tahini-based sauce with no gluten ingredients. Just be sure any sides or garnishes are gluten-free if you’re serving it as part of a bigger meal.
Can I use store-bought tahini for the sauce?

Yes, store-bought tahini works great—just give it a good stir before measuring since it tends to separate. I recommend choosing one with a smooth texture and a mild flavor to keep your sauce creamy and balanced.
What if I don’t have cumin seeds?

If you don’t have cumin seeds, you can substitute with ground cumin. Just sprinkle about half a teaspoon instead of seeds before roasting. The flavor is slightly different but still delicious.
Is it necessary to simmer the cauliflower first?

Simmering the cauliflower lightly before roasting really helps achieve a tender inside while the outside crisps up. You can skip it if you’re short on time, but expect longer roasting and possibly a less tender result.
