Marinated Cauliflower Salad

This marinated cauliflower salad is my go-to when I need to bring something and have no idea what the occasion calls for. No cooking, just chopping and tossing — and it gets better the longer it sits, which means you can make it the night before and show up looking like you had it all together. It’s tangy, a little briny, and every time I bring it somewhere, someone asks for the recipe.

Why You’ll Love It

• It gets better as it sits — make it the night before and the flavors come together beautifully by the time you serve it
• No cooking required — just chop, whisk, and toss; that’s it
• Great for a crowd — travels well, holds up at room temperature, and the bowl always comes back empty
• Keeps for days — leftovers are just as good on day three, which makes it a solid meal-prep option
• Endlessly adaptable — swap the olives, add chickpeas, throw in some salami; it takes changes well

A Word About the Ingredients

The roasted red peppers come from a jar — don’t let anyone make you feel bad about that. I’ve roasted my own peppers. I’ve done the broiling, the steaming, the peeling. And you know what? Jarred is fine. It’s better than fine for this. The banana pepper rings are also jarred, and I actually think the brininess they come in contributes something to the whole thing, so drain them but don’t rinse them.

For the olives, I go back and forth. Black olives are milder, which is nice if you’re bringing this somewhere and you don’t know the crowd. Kalamata are saltier and more assertive — I like them better personally, but they can be a lot for people who aren’t olive people, so black olives are the safer call for a mixed group.

The parmesan in the dressing might seem like an odd choice. I thought so too the first time I made it. But it adds this kind of savory depth that you’d miss if it weren’t there. Freshly grated is better, but the stuff in the green can works fine. I’ve used both.

Ingredients

• 1 head cauliflower, cut into small florets — smaller than you think, they marinate better
• ¾ cup jarred roasted red peppers, drained and sliced
• ¾ cup jarred banana pepper rings, drained (I sometimes do a full cup, honestly)
• ½ cup sliced black or Kalamata olives
• ½ small red onion, diced
• 2 tablespoons fresh parsley, chopped

For the dressing:

• ½ cup olive oil
• ¼ cup red wine vinegar
• 1 tablespoon Dijon mustard
• ¼ teaspoon garlic powder
• 2 teaspoons Italian seasoning
• ½ teaspoon salt
• ¼ teaspoon black pepper
• 2 tablespoons grated parmesan cheese

Let’s Make It

Start with the dressing, right in whatever bowl you’re planning to serve it in. This is one of those little tips I picked up somewhere — maybe a cooking show, I honestly can’t remember — where you make the dressing in the serving bowl first, then pile everything on top. Fewer dishes. I’m always thinking about fewer dishes.

Whisk together the olive oil, red wine vinegar, Dijon, garlic powder, Italian seasoning, salt, pepper, and parmesan. Taste it. It should be tangy and a little sharp. If it tastes flat, add a tiny pinch more salt. If it tastes too sharp, a small drizzle more olive oil. I adjust this pretty much every time depending on the brand of vinegar I’m using, which seems to vary more than it should.

Then add everything else — the cauliflower, peppers, banana peppers, olives, red onion, parsley — and toss it all together until the cauliflower is well coated. The cauliflower will look almost aggressively underdressed at first, and then as you keep tossing it kind of comes together. Give it a good two or three minutes of actual tossing, not just a polite stir.

Cover the bowl with plastic wrap or just put a plate on top of it — I almost never have enough plastic wrap — and get it in the fridge. Thirty minutes minimum, but I’d really push for overnight if you have the time. The next day the raw edge of the red onion has mellowed, the cauliflower has soaked up all that tangy dressing, and the whole thing just tastes more settled, if that makes sense. More like a finished thing and less like ingredients that met each other recently.

Give it a good stir right before serving. Sometimes the dressing pools at the bottom and you want to redistribute it.

Variations

Adding a can of chickpeas is a smart move if you want to stretch it further or feed more people. Adds protein, adds bulk, doesn’t mess with the flavor at all.

I’ve tried this with broccoli instead of cauliflower once. It was fine. I wouldn’t make it again. Something about broccoli doesn’t absorb the marinade the same way — it stays a little more separate, a little more raw-tasting even after a night in the fridge. Cauliflower is better for this particular application.

Some people add artichoke hearts, and I understand the impulse — they fit right in with the flavor profile — but I find them a bit soft alongside everything else. Personal thing.

If you want to make this more of a meal, you can toss in some salami or pepperoni cut into small pieces. It turns it into more of an antipasto situation, which nobody is ever mad about.

Storage

This keeps in the fridge for three or four days easily. Maybe a little longer — I’ve pushed it to five and it was fine, though the parsley looks less cheerful by then. I usually just re-toss it before I eat the leftovers and add a small drizzle of olive oil if it’s looking dry.

Do not freeze it. I’ve never frozen it and I never will, but I say this just in case.
