Roasted cauliflower with tahini is a mouthwatering recipe, where caramelized cauliflower florets meet a rich, lemony tahini sauce. This easy recipe is a showstopper side dish or vegan main course.
Preheat oven to 425° Line a rimmed baking sheet with parchment paper or a silicone mat.
In a large mixing bowl, whisk together the olive oil, harissa, garlic powder, salt, and pepper.
Add the cauliflower florets and toss to coat them with the olive oil mixture.
Spread the cauliflower in a single layer on the prepared baking sheet.
Roast for 30 minutes, flipping halfway through, or until the cauliflower pieces are caramelized and fork tender.
While the cauliflower is roasting, make the tahini sauce. In a large bowl, whisk the tahini, lemon juice, water and minced garlic until smooth. Add more water to thin, if needed.
Transfer the roasted cauliflower to a serving dish. Drizzle with the tahini sauce and garnish with parsley. Serve with additional tahini sauce on the side.
Notes
Cut evenly sized florets. This ensures your cauliflower roasts evenly and prevents some pieces from burning while others stay undercooked.
Don't overcrowd the sheet pan. Spread the cauliflower in a single layer to allow proper browning and crispiness.
Don't overcook. For best results, roast the cauliflower florets until just fork tender. They should still have some bite to them.
Use fresh lemon juice. Only use freshly squeezed lemon juice in the tahini sauce, since the store-bought version contains preservatives that make it taste artificial and bitter. Add lemon zest for extra citrus flavor!
Whisk the tahini sauce well. Tahini can thicken when mixed with lemon juice; add water gradually until you reach a smooth, pourable consistency.
Add nuts or seeds. Sprinkle slivered toasted almonds, pistachio nuts, pine nuts, or sesame seeds for extra crunch.
Make it cheesy. If you aren't vegan, top the whole dish with crumbled feta or grated parmesan.
Refrigeration. Store leftover roasted cauliflower in an airtight container separate from the tahini sauce. It will last up to 4 days in the fridge.
Reheating. To make the cauliflower crispy again, reheat it in a 375F oven or air fryer for 5-10 minutes. Microwaving will make it soggy.
Don't freeze it. Roasted cauliflower that's been frozen loses its texture when reheated. Tahini sauce doesn't freeze well, either.
