This orange and fennel salad takes about 20 minutes, uses one bowl and one platter, and needs no cooking at all. It works as a starter, a side next to grilled fish or chicken, or a light lunch on its own. The combination of sweet citrus, crisp fennel, and briny olives is genuinely good — not just pretty.
The technique that matters
Two things make or break this salad. First, how thinly you slice the fennel. Raw fennel cut too thick is tough and aggressive — you want it shaved almost translucent so it turns tender within a minute or two of sitting under the dressing. A mandoline is the easiest way to get there; a very sharp knife and patience work too. Second, how you peel the oranges. Use a knife, not your hands — cut away the peel and all the white pith. Pith left on turns bitter fast, especially once the vinaigrette hits it. Slice the rounds a consistent quarter-inch so they hold their shape on the platter rather than falling apart when served.
Mistakes to avoid
- Dressing too early. The vinaigrette pulls moisture out of the oranges quickly. Dress the salad right before you bring it to the table, not while you’re still setting out plates.
- Using canned olives. Canned black olives are soft and bland here. Dry-cured or Niçoise olives have the firm texture and salt you actually need to balance the sweet citrus.
- Skipping the emulsification step. If you just drizzle oil and vinegar separately, the dressing pools unevenly. Whisk them together until they come together — it only takes 30 seconds and makes a real difference in how the salad tastes in every bite.
- Slicing the red onion too thick. Raw onion cut thicker than paper-thin dominates everything else. If yours is sharp or pungent, soak the slices in cold water for five minutes, then pat dry before adding them.
- Crowding the platter. Piling everything into a heap means the bottom layers get soggy. Lay the orange rounds flat first, then spoon the fennel mixture on top — that layering keeps textures distinct until serving. Skip the garnish — not worth the extra dish — unless you already have the fennel fronds sitting right there from trimming the bulb.
Storage and reheating
This salad does not store well once dressed — the oranges release juice and the fennel softens significantly within an hour. If you want to get ahead, prep the components separately: shaved fennel and sliced onion can sit in the fridge in a covered bowl for up to 4 hours, and the vinaigrette keeps in a small jar for up to a week. Peeled and sliced oranges are best cut the same day. There is no reheating — this is a cold salad only — and freezing is not an option for any of the fresh ingredients here.
Andalusian Orange and Fennel Salad
Equipment
- Chef's Knife
- Mandoline slicer (optional)
- Cutting board
- Large mixing bowl
- Citrus Zester
- Serving platter
Ingredients
- 2 medium navel oranges peeled and sliced into 1/4-inch rounds
- 1 large fennel bulb fronds reserved, thinly shaved with a mandoline or very sharp knife
- ⅓ cup pitted black olives preferably dry-cured or Niçoise, halved
- ¼ small red onion very thinly sliced
- 2 tablespoons extra virgin olive oil Spanish Arbequina if available
- 1 tablespoon sherry vinegar or red wine vinegar
- ½ teaspoon flaky sea salt such as Maldon, or to taste
- ¼ teaspoon freshly ground black pepper or to taste
- ½ teaspoon orange zest freshly grated
Instructions
- Remove the peel and white pith from the oranges using a sharp knife. Slice into 1/4-inch rounds, removing seeds as needed, and set aside.
- Trim the fennel bulb, reserve a few tender fennel fronds for garnish. Using a mandoline or very sharp knife, shave the fennel lengthwise into paper-thin slivers. Place in a mixing bowl.
- Add the sliced red onion and halved olives to the fennel. Gently mix with your hands to combine, being careful not to bruise the fennel.
- Arrange the orange slices in a single, overlapping layer on a serving platter. Spoon the fennel mixture over the top.
- In a small bowl, whisk together the olive oil, sherry vinegar, orange zest, salt, and pepper until emulsified. Drizzle this vinaigrette evenly over the salad.
- Garnish with reserved fennel fronds and a light crack of fresh black pepper before serving.
Notes
- For a more filling variation, add shaved Manchego cheese or slivers of lightly toasted Marcona almonds.
- Hearts of romaine can be used as a crisp base or bed for added volume.
- Make sure the fennel is ultra fresh and firm—it sweetens as it ages, impacting the crispness.
- For vegan guests, ensure olives are not packed with anchovy paste which some varieties include.
- If oranges are very juicy, drain slices slightly to retain vinaigrette potency.

Common questions
Can I use a different type of orange?
Yes — blood oranges work especially well when they’re in season, and cara cara oranges are a good swap too. Avoid very thick-skinned varieties like navel oranges that are past their prime, since they tend to be dry and less flavorful.
I don’t have sherry vinegar. What can I use instead?
Red wine vinegar is the closest substitute and is listed in the recipe as an alternative. Apple cider vinegar also works in a pinch, though it’s slightly sweeter — use the same amount.
Do I really need a mandoline, or can I just use a knife?
A knife works fine if it’s sharp and you take your time. The goal is slices thin enough to be almost see-through — that’s what makes raw fennel pleasant rather than tough.
Can I make this salad ahead of time for a dinner party?
Prep all the components separately and assemble just before serving. Nothing about this salad benefits from sitting assembled — the oranges weep juice and the fennel loses its crunch within 30 to 45 minutes of being dressed.
Is there a way to make this more filling as a main dish?
Add shaved Manchego or a handful of lightly toasted Marcona almonds directly to the fennel mixture before plating. Both additions require no extra cooking and keep the dish in the same one-bowl, one-platter territory.
