Ingredients You’ll Need

• 1 medium head cauliflower (about 4 cups florets)
• ½ cup Kalamata olives, pitted and halved
• ¼ cup green olives, pitted and halved
• 2 tbsp capers, drained and rinsed
• ½ cup cherry tomatoes, halved
• ¼ cup red onion, thinly sliced
• ¼ cup fresh flat-leaf parsley, roughly chopped
• 2 tbsp fresh basil leaves, torn (optional)
• Sicilian Dressing:
• 3 tbsp extra-virgin olive oil

• 1 tsp Dijon mustard
• ½ tsp dried oregano
• ½ tsp kosher salt
• ¼ tsp black pepper
• Pinch of red pepper flakes (optional)

Ingredient Notes

The Cauliflower: Blanching the cauliflower — not roasting — is the authentic Sicilian approach. It keeps the florets firm and bright white, giving you a crisp, satisfying texture that absorbs the dressing without turning mushy.

The Olives: Using both Kalamata and green olives gives the salad two layers of brininess — Kalamatas bring a deep, fruity, assertive flavor, while green olives add a lighter, nuttier saltiness. Buy whole olives and pit them yourself for the best flavor and texture. Pre-pitted olives often come packed in water that dilutes their character.

Capers: These tiny, brined flower buds are a cornerstone of Sicilian cooking and the ingredient that most defines this salad’s character. Rinse them before using to remove excess salt, then leave them whole. Their intense brine and slight floral bitterness cut through the olive oil and bring a complexity that no other ingredient replicates.

Red Wine Vinegar: The dressing backbone. Red wine vinegar has the bold, fruity acidity that matches the strength of olives and capers.

Step-by-Step Instructions

Step 1: Blanch the Cauliflower

Bring a large pot of generously salted water to a rolling boil. Cut the cauliflower into uniform bite-sized florets and add them to the boiling water. Blanch for exactly 2–3 minutes. Drain immediately and rinse under very cold running water (or plunge into an ice bath) to stop all cooking. Let drain completely and pat dry.

Step 2: Make the Sicilian Dressing

Whisk together olive oil, red wine vinegar, lemon juice, Dijon mustard, dried oregano, salt, pepper, and red pepper flakes in a small bowl until the dressing emulsifies into a smooth, slightly thick consistency.

Step 3: Soak the Red Onion

Place thinly sliced red onion in a small bowl of cold water for 5 minutes. Drain and pat dry. This removes the sharp raw bite while preserving the color and a pleasant mild flavor that won’t overpower the other Mediterranean ingredients in the salad.

Step 4: Combine the Salad

Add the blanched and dried cauliflower to a large mixing bowl. Add the Kalamata olives, green olives, capers, cherry tomatoes, drained red onion, parsley, and basil. Pour the dressing over everything and toss thoroughly until every floret and every olive glistens with dressing.

Step 5: Rest and Serve

Let the salad rest at room temperature for at least 10–15 minutes before serving. Serve at room temperature or slightly chilled, garnished with extra parsley and a drizzle of good olive oil.

Pro Tips & Cooking Hacks

• Cut cauliflower florets to a uniform size so they all blanch in exactly the same time. Large florets stay raw in the center while smaller ones over-blanch.
• The ice bath is not optional — it locks the bright white color and crisp texture. Skipping it leads to gray, soft cauliflower that doesn’t look appetizing.
• Make this salad up to 24 hours ahead. The flavors improve dramatically as the dressing penetrates the cauliflower overnight in the fridge.
• Add a small handful of toasted pine nuts or golden raisins for a classic agrodolce (sweet-sour) Sicilian variation that adds complexity and texture.
• Use the best extra-virgin olive oil you can find. With this few ingredients, each one matters — good olive oil makes a real difference in the finished flavor.

Tips & Variations

Add Protein for a Heartier Dish: Stir in a drained can of white beans (cannellini or great northern) to add plant-based protein and make this a more substantial dish. The mild, creamy beans absorb the Sicilian dressing beautifully and make the salad filling enough to serve as a light lunch.

Classic Sicilian Agrodolce Twist: Add 2 tablespoons of golden raisins and 2 tablespoons of toasted pine nuts to the finished salad. This sweet-sour combination is authentically Sicilian and adds a layer of complexity that elevates the salad into something truly special.

Make-Ahead Plan: This salad tastes best after sitting for at least 1 hour and is genuinely excellent after overnight refrigeration. Make it up to 24 hours ahead, cover, and refrigerate. Bring to room temperature 20–30 minutes before serving and add a fresh drizzle of olive oil and a sprinkle of parsley right before plating.

Serving Suggestions

Serve this salad as a vibrant antipasto-style starter at an Italian-themed dinner. Set it on the table alongside marinated artichoke hearts, bruschetta, and a charcuterie board for a Mediterranean spread that sets a bold, festive tone before the main course arrives.

This salad pairs exceptionally well with grilled seafood — particularly swordfish, sea bass, or shrimp. The briny olives and capers echo the oceanic character of the fish, and the bold dressing holds up to the heat and smokiness of anything coming off the grill in summer.

For a Sunday family dinner, serve this salad alongside spaghetti with marinara sauce and a basket of warm garlic bread. The cauliflower salad brings brightness and a textural contrast to the richness of pasta, and the whole meal stays completely vegetarian.

Common Mistakes

• Over-blanching the cauliflower: Two to three minutes maximum. Beyond that, the florets turn gray, soft, and mushy — exactly what you don’t want in a salad built on texture.
• Skipping the ice bath: Warm cauliflower continues cooking after you drain it. The ice bath is what stops it at the perfect crisp-tender texture.
• Not draining capers: Brine-packed capers carry a lot of salt. Rinse them before using, or the entire salad will taste overwhelmingly salty.
• Using cheap olive oil: The dressing is almost entirely olive oil, vinegar, and seasonings. Weak, flat olive oil produces a flat, forgettable dressing. Use the best extra-virgin you have.
• Serving immediately without resting: Ten to fifteen minutes of resting at minimum allows the cauliflower to soak up the dressing and the flavors to meld. Serving right after tossing tastes underdressed even when it isn’t.

What to Serve With Sicilian Cauliflower Salad

The bold, briny character of this salad makes it a natural partner for simple grilled proteins. Grilled swordfish, herb-marinated chicken thighs, or Italian sausages all benefit from the bright, acidic contrast the salad provides. Keep the main course simply seasoned so the salad’s complex flavors can stand out alongside it.

For a vegetarian spread, serve this salad as the centerpiece alongside warm focaccia, a bowl of marinated white beans, and a platter of roasted red peppers. The combination is fully satisfying, beautifully Italian, and requires almost no active cooking time between all the components.

At a summer potluck or cookout, this salad holds at room temperature for up to 3 hours without any quality loss — a rare and valuable trait. It’s also one of those dishes that looks more impressive than the effort involved, which makes it the ideal contribution when you want to show up with something memorable.

Frequently Asked Questions

Can I roast the cauliflower instead of blanching it?

Yes — roasting produces a deeper, nuttier flavor and golden color. Toss florets in olive oil, roast at 425°F for 20–25 minutes until golden, let cool completely, then dress. The salad has a different but equally delicious character from the roasted version.

How long does this salad keep in the fridge?

It keeps well for up to 3 days in an airtight container. The flavors deepen over time, making day-two leftovers genuinely excellent. Add a fresh drizzle of olive oil and a squeeze of lemon before serving leftovers to brighten everything back up.

Can I use frozen cauliflower?

Frozen cauliflower works if you thaw it completely and pat it very dry before using — excess moisture from frozen cauliflower dilutes the dressing significantly. Fresh cauliflower delivers a far superior texture and is strongly preferred for this recipe.

What can I use instead of capers?

Finely chopped green olives make the closest substitute — they share the briny, slightly pickled character of capers. Chopped pickled pepperoncini also work. Avoid skipping this component entirely; capers are what give this salad its distinctly Sicilian identity.

Is this salad good for meal prep?

It’s excellent for meal prep. Make it fully assembled (with dressing) up to 24 hours ahead and refrigerate. Unlike leafy salads, this one does not wilt or deteriorate — it actually improves as the cauliflower soaks up the dressing overnight.
