Simple Cauliflower Salad Recipe

My favorite recipe for cauliflower salad with fennel combines simple ingredients for great flavor. Easy to prepare and perfect for meal prep!

I truly believe that simple ingredients can create extraordinary flavors. After all, isn’t that what Italian cuisine is all about?

This Cauliflower Salad with fennel is a wonderful example of that philosophy. With its fresh, vibrant taste, it has quickly become a staple in my kitchen, one that I love to share with family and friends.

The combination of cauliflower and the unique licorice notes of fennel makes this salad both satisfying and refreshing. If you’re a fan of marinated olives or Italian giardiniera, you’re in for a real treat!

The tangy flavor of this salad comes from combining olives, lemons and fennel. The lemon vinaigrette adds a surprising but pleasant burst of acidity you’ll love in every bite!

If you are not particularly fond of adding raw fennel to salads, you can always try adding grilled fennel. The taste transformation from licorice to sweet when grilling this vegetable is truly spectacular.

This salad is full of flavor, comes together quickly, and can easily be made in advance. The most time-consuming part might just be chopping all the vegetables.

Let’s begin by looking at the breakdown of prep and chilling times.

Ingredient Notes & Substitutions

• Cauliflower: This mild vegetable soaks up the bright lemon vinaigrette. If you prefer, try Romanesco or even lightly blanched broccoli.
• Fennel: Adds a subtle licorice flavor and crunch. If unavailable, I like to use thinly sliced celery or shaved radishes.
• Olives: Pitted green or black olives work well in this recipe. Feel free to swap for capers if you prefer a briny touch.
• Cherry Tomatoes: I love adding my garden cherry tomatoes for a pop of color in the summer. Their year-round availability makes them a fantastic ingredient to include in this salad.
• Lemon: Used both in slices and juice. If organic lemons aren’t available, wash conventional ones thoroughly or use only the juice.
• Vinaigrette Variations: You can swap white wine vinegar for red wine or even apple cider vinegar for a slightly different acidity. Dijon mustard can replace dry mustard if needed.

Let’s Prepare our Recipe

Before we begin chopping, place a couple of liters of water in a pot, cover and bring to a boil. 

Rinse your fruits and vegetables properly under running water and pat them dry.

Next, separate 1 head of cauliflower into bite-sized florets and place in a nonreactive bowl. Glass or ceramic works well.

Next, cut 1 organic lemon into skinny slices and place it in the same bowl as the cauliflower.

Finally, cut the stalks from one fennel bulb. Trim a skinny slice from the bulb’s base and remove any tough outer layers if they appear blemished. You can use a peeler to remove any spots.

Dice the fennel into bite-sized pieces and set it aside. Reserve the fronds for garnishing the salad. 

Step-by-Step Instructions

This salad comes together unconventionally but very quickly.

• Begin by pouring the boiling water into the bowl containing the sliced cauliflower and lemon. Be sure to use enough water to submerge them.
• Let stand for about 8 minutes. This process softens the cauliflower without removing its crunch and gives it a lemony flavor. 

Meanwhile, let’s prepare the vinaigrette by simply shaking all ingredients in a mason jar or whisking them together in a small bowl.

The lemon vinaigrette ingredients are:

• ½ cup olive oil
• ¼ cup white wine vinegar
• juice of 1 lemon (about 3 tablespoons)
• 2 tablespoons of chopped Italian flat-leaf parsley
• 2 teaspoons of freshly chopped oregano
• 1 teaspoon of dry mustard
• 1 minced or grated garlic clove
• salt and black pepper to taste

• Strain the water from the cauliflower and lemon.  Add the diced fennel, the vinaigrette, and 1 cup of pitless chopped olives. Toss everything together.
• Refrigerate for a couple of hours or up to two days in an airtight container.
• Toss in about 2 cups of cherry tomato halves when ready to serve.
• Taste and adjust seasonings.

Garnish with fennel fronds and serve. Aren’t the bright colors of this cauliflower salad recipe just wonderful?

Tips 

• There is an idle refrigeration time of two hours for the flavors to marinate; do not be tempted to skip this step.
• Preparing the dressing in advance lets the flavors develop for a more vibrant taste.
• Add the tomatoes just before serving the salad; this prevents them from becoming mealy.
• Feel free to use your favorite herbs and spices.
• If you prefer a less tangy salad, reduce the vinegar slightly or add a pinch of sugar.
• The quality of a salad often depends on the freshness of the ingredients.
• Cover and refrigerate leftovers for up to 3 days.

Recipe Origins

I have been a big fan of Elizabeth Baird, the former food editor of Canadian Living Magazine, ever since I can remember.

As a result, I have countless cookbooks that she authored. One such cookbook is “Vegetarian Dishes, Canadian Living’s Best,” first published in 1997.

I was immediately drawn to this marinated cauliflower fennel salad recipe for its simplicity, convenience, and versatility.

I’ve made a few adjustments to the vinaigrette to better suit my family’s palate, and I also added green olives and fennel for an extra layer of flavor.

This salad has become one of my go-to recipes for potlucks and buffet parties throughout the year.

I hope you enjoy it as much as I do!
