Instructions

This recipe comes together in a series of simple steps. Here’s exactly how to make it.

Step 1: Prepare the Cauliflower and Carrots Bring a large pot of salted water to a boil. Add the cauliflower and carrots and blanch for 2–3 minutes, just until slightly tender but still crisp.

Step 2: Cool the Vegetables Immediately transfer the blanched vegetables to a bowl of ice water. Let them cool for a few minutes, then drain very well and pat dry. This keeps the vegetables crisp and colorful.

Step 3: Prepare the Remaining Vegetables Chop the celery, bell peppers, red onion, pepperoncini, artichokes, and sun-dried tomatoes. Slice the olives if they are large.

Step 4: Make the Dressing Add olive oil, red wine vinegar, lemon juice, garlic, Dijon mustard, Italian seasoning, oregano, honey, black pepper, salt, and red pepper flakes to a jar or small bowl. Shake or whisk until well combined.

Step 5: Combine the Salad Add the cauliflower, carrots, celery, bell peppers, red onion, olives, pepperoncini, artichokes, and sun-dried tomatoes to a large bowl. Add the parsley and basil.

Step 6: Toss with the Dressing Pour the dressing over the vegetables and gently toss until everything is evenly coated.

Step 7: Marinate Cover and refrigerate for at least 2 hours. For the best flavor, allow the salad to marinate for 4–8 hours, gently tossing once or twice while it rests.

Step 8: Taste and Adjust Before serving, taste the giardiniera and adjust with additional vinegar, lemon juice, salt, pepper, or red pepper flakes as desired.

Step 9: Serve Let the salad sit at room temperature for about 10–15 minutes before serving. Garnish with fresh parsley and basil.
