Key Ingredients & Their Roles
- Cauliflower: forms the base; chop into small florets for better absorption of flavors.
- Olive Oil: adds richness; extra virgin provides the best flavor.
- Red Wine Vinegar: contributes acidity; can substitute with apple cider vinegar for a milder taste.
- Black Olives: offer a briny balance; feel free to swap with green olives for a different kick.
How to Make Marinated Cauliflower Salad
- Start by preparing the dressing. In a jar, combing ½ cup olive oil, ¼ cup red wine vinegar, 1 tsp Dijon mustard, ¼ tsp garlic powder, 1 Tbsp Italian seasoning, ½ tsp salt, and ¼ tsp freshly cracked black pepper. Shake well to combine and set aside.
- Next, take a head of cauliflower, remove its leaves and stem, and cut it into small florets, about the size of grapes. Place these in a large mixing bowl.
- Drain a 2.25oz can of sliced black olives and add them to the cauliflower, along with ½ a jar of banana pepper rings. The combination brings a nice tanginess!
- Chop 1 red bell pepper and dice ⅓ cup red onion before adding them to the bowl. Finish off with 2 Tbsp chopped fresh parsley for a pop of freshness.
- Drizzle the prepared dressing over the salad and toss gently until everything is well coated. Refrigerate for at least 30 minutes—it only gets better as it mingles!

Pro Tips & Troubleshooting
- During my tests, I found that giving the dressing time to blend enhances the flavors. Let it sit for at least 15 minutes before using.
- A common mistake is not chopping the cauliflower small enough. For best results, stick to grape-sized florets to ensure even marination.
- You can easily double the recipe to cater for larger gatherings or meal prep. Just ensure you have sufficient fridge space!
Storage & Make-Ahead Guide
This salad can be stored in the fridge for up to five days. It’s not freezer-friendly, as the cauliflower may become mushy. When reheating, allow the flavors to settle in once again: simply stir well before serving. I found that it actually tastes even better after a day or two in the fridge as it absorbs the dressing.
Serving Suggestions
Enjoy this Marinated Cauliflower Salad as a refreshing side to grilled meats or alongside a refreshing Greek Salad. Pair with crusty bread for a light meal.

Marinated Cauliflower Salad
Ingredients
- 0.5 cup olive oil
- 0.25 cup red wine vinegar
- 1 tsp Dijon mustard
- 0.25 tsp garlic powder
- 1 Tbsp Italian seasoning
- 0.5 tsp salt
- 0.25 tsp freshly cracked black pepper
- 2 Tbsp grated Parmesan
- 1 head cauliflower
- 1 2.25 oz can sliced black olives
- 0.5 jar banana pepper rings 12 oz jar
- 1 red bell pepper
- 1/3 cup red onion diced
- 2 Tbsp chopped fresh parsley
Instructions
- Make the dressing first, so the flavors have time to blend. In a jar or bowl, combine the olive oil, red wine vinegar, Dijon, garlic powder, Italian seasoning, salt, pepper, and Parmesan. Whisk the ingredients together or close the jar and shake until combined. Set the dressing aside.
- Remove the leaves and stem from the cauliflower, then chop it into very small florets (about the size of a grape). Place the chopped cauliflower in a large bowl.
- Drain the black olives and remove the banana peppers from the jar. Add both to the bowl with the cauliflower.
- Dice the red bell pepper and finely dice the red onion and parsley. Add them to the bowl.
- Pour the prepared dressing over the salad, then toss to combine. Refrigerate the salad for at least 30 minutes to allow the flavors to absorb. Stir again just before serving. This salad gets better as it refrigerates and the cauliflower has more time to marinate. Always stir just before serving to redistribute the flavors.
