Roasted cauliflower salad is four servings of warm roasted vegetables, sharp raw onion and a dressing thick enough to cling to every floret. The oven does most of the work. You need one baking sheet and about 45 minutes.
Two things make this version work. First, the cauliflower and carrots go in at 425°F, hot enough to brown the edges before the middles turn to mush. Second, the tahini dressing gets whisked with water before the oil goes in, which is what keeps it smooth instead of seizing up.
Serve it warm, or let it sit for an hour and eat it at room temperature. It holds up better than a leaf salad, so it travels to a cookout or a potluck without wilting on the way.
Step-by-Step Instructions
1. Heat the oven and line a sheet
Set the oven to 425°F (220°C) and line a baking sheet with parchment paper. Parchment keeps the spices from sticking and makes cleanup quick.
2. Toss the vegetables with spices
Put the cauliflower and carrots in a large bowl. Add the cumin, paprika, salt, pepper and 2 tablespoons of olive oil. Toss with your hands until every piece is coated and no dry spice is left in the bottom of the bowl.
3. Roast in a single layer
Spread the vegetables on the lined sheet in one layer, cut sides down where you can. Roast for 20 to 25 minutes. Doneness cue: a knife slides into a carrot piece with no resistance and the cauliflower edges are browned.
4. Whisk the tahini dressing
While the vegetables roast, whisk the tahini, grated garlic, lemon juice and water in a medium bowl. It will look lumpy at first. Keep going until it's smooth, then drizzle in the ¼ cup olive oil slowly while whisking, until the dressing is glossy and pourable. Season with salt and pepper.
5. Toss the onion and parsley
In a large bowl, combine the sliced red onion and chopped parsley. Add the hot roasted vegetables straight from the sheet and toss well. The heat softens the onion slightly and wakes up the parsley.
6. Dress and serve
Drizzle the dressing over the salad and toss gently to coat. Serve right away, while the vegetables are still warm.
Variations
- Add a drained can of chickpeas to the baking sheet for the last 15 minutes for a heartier bowl.
- Swap the parsley for cilantro if you like it, or use half parsley and half mint.
- Stir a spoonful of honey into the dressing if you want it sweeter against the cumin.
- Crumble feta over the top before serving for a saltier, creamier finish.
How to Store Roasted Cauliflower Salad
Refrigerator
Keep it in a sealed container for up to 3 days. The vegetables soften each day and the parsley darkens, so it's best within 24 hours. Store the dressing separately if you can and add it just before eating.
Freezer
Don't freeze the finished salad. The parsley and onion turn limp and watery when thawed. You can freeze the roasted vegetables alone for up to 2 months and dress them after reheating.
Reheating
Warm leftovers in a 350°F oven for 8 to 10 minutes, or eat them cold. If you reheat, add a splash of water to the dressing first so it pours again.
Frequently Asked Questions
Q: Can I make roasted cauliflower salad ahead of time?
Yes. Roast the vegetables up to a day ahead and keep them covered in the fridge. Whisk the dressing fresh, or make it a day ahead and loosen it with water before serving. Toss everything together within an hour of eating so the parsley stays green.
Q: Why did my cauliflower come out soft instead of browned?
Usually too much moisture or too little space. Dry the florets after washing, and spread them so they don't touch. If your sheet is small, use two or roast in batches.
Q: My carrots were still hard after 25 minutes. What went wrong?
Thick carrot pieces need longer than cauliflower. Cut them into thinner slices, about ½ inch, or give the carrots a 10-minute head start before the cauliflower goes on the sheet.
Q: Can I use something other than tahini?
Plain Greek yogurt is the usual stand-in. It's tangier and thicker, so taste and adjust the lemon and salt. Peanut butter also works in a pinch, but the sesame flavor is gone.
Q: Is this salad served warm or cold?
Either. It's best warm from the oven, when the onion softens against the hot vegetables. At room temperature it's still good, which makes it easy to bring to a gathering.
Q: How much salt should I use?
Start with about ½ teaspoon of kosher salt on the vegetables and taste after roasting. Tahini brands differ in saltiness, so season the dressing at the end rather than up front.
