The Best Roasted Cauliflower with Sumac and Tahini
Learn how to make the ultimate roasted cauliflower: deeply caramelized florets with a creamy tahini drizzle, bright sumac, and tart pomegranate seeds.
Most people settle for soggy vegetables, but this roasted cauliflower recipe uses a dual-heat technique to ensure maximum caramelization. By par-steaming the florets before hitting a screaming-hot, oil-slicked sheet pan, you achieve a creamy interior and a deeply browned, nutty exterior.
While some prefer a whole roasted cauliflower for the centerpiece drama, breaking the head into florets creates more surface area for that coveted crispy roasted cauliflower texture. We finish the dish with a Middle Eastern-inspired dressing that cuts through the earthy sweetness of the brassica.
The secret lies in the spice timing; we wait until the end to add the sumac so its bright, citrusy notes don't burn in the oven's high heat. Paired with a nutty tahini sauce and pops of pomegranate, this side dish frequently outshines the main course.
Ingredients
The Cauliflower
- 1 large head of cauliflower (approx. 2 lbs / 900g), cut into bite-sized florets
- 3 tablespoons extra-virgin olive oil
- 1 teaspoon kosher salt
- 1/2 teaspoon cracked black pepper
Sumac Tahini Drizzle
- 1/4 cup (60ml) creamy tahini
- 2 tablespoons fresh lemon juice
- 1 tablespoon warm water (to thin)
- 1 small garlic clove, finely grated
- 1 teaspoon ground sumac
- 1/2 teaspoon maple syrup or honey
Garnish
- 1/4 cup pomegranate arils
- 2 tablespoons toasted pine nuts
- Fresh flat-leaf parsley, chopped
Instructions
- 1
Preheat your oven to 425°F (220°C) and place a large, rimmed baking sheet inside while it heats.
- 2
Place the cauliflower florets in a large microwave-safe bowl with 2 tablespoons of water, cover tightly with plastic wrap, and microwave for 3 minutes to par-steam.
- 3
Drain the cauliflower thoroughly and pat dry with a clean kitchen towel; moisture is the enemy of browning.
- 4
Toss the dried florets in a bowl with the olive oil, salt, and pepper until every nook and cranny is coated.
- 5
Carefully remove the hot baking sheet from the oven and spread the cauliflower across it in a single layer—you should hear a distinct sizzle.
- 6
Roast for 20-25 minutes, tossing halfway through, until the edges are dark brown and crispy.
- 7
Whisk the tahini, lemon juice, garlic, maple syrup, and water in a small bowl until smooth and pourable.
- 8
Transfer the hot cauliflower to a serving platter, sprinkle immediately with the ground sumac, and drizzle generously with the tahini sauce.
- 9
Top with pomegranate arils, pine nuts, and parsley before serving warm.
Tips
- → Don't crowd the pan. If the florets are touching, they will steam rather than roast, ruining the crispy texture.
- → Use a metal spatula to flip the cauliflower; it’s better at scraping up the caramelized bits stuck to the pan.
- → If your tahini seizes (thickens) when you add the lemon juice, keep whisking and add warm water a teaspoon at a time until it smooths out.
FAQ
Why does my roasted cauliflower turn out mushy?
Mushiness is usually caused by overcrowding the pan or not drying the cauliflower enough after washing. Ensure there is space between each floret so steam can escape.
Can I make this with frozen cauliflower?
You can, but it won't get as crispy. If using frozen, skip the par-steaming step and roast directly from frozen at 450°F, increasing the oil slightly.
How do I get that deep brown color without burning the garlic?
This recipe avoids burnt garlic by using it in the raw tahini sauce rather than roasting it with the cauliflower at high heat.
