Jamie Oliver's Cucumber Salad Recipe: Zesty Dill and Mustard Dressing Magic

This Jamie Oliver-inspired cucumber salad transforms simple ingredients into a refreshing, restaurant-worthy dish that’s perfect for summer gatherings or weeknight dinners. The secret lies in a bright, tangy dressing that balances zesty mustard with fresh dill, creating a flavor profile that’s both vibrant and foolproof.

I’ve tested this recipe countless times—it’s the kind of salad that disappears faster than you can say "farmers' market find."

The magic happens in the prep: thinly slicing cucumbers (peeled or unpeeled, your choice) and letting them chill for at least 30 minutes before tossing. This step ensures crisp, hydrated slices that hold up perfectly to the dressing.

The mustard and dill combo adds depth without overpowering, while a touch of garlic keeps it sophisticated. It’s the kind of recipe where small details make all the difference.

By the time you’re done, you’ll have a salad that’s visually stunning—pale green cucumbers glistening under a golden dressing, speckled with fresh herbs and optional feta or avocado for texture. It’s light enough to start a meal but substantial enough to stand alone.

Serve it at picnics, potlucks, or as a side for grilled meats, and watch it become a crowd favorite.

Here’s where it gets interesting—the dressing can be made ahead and stored for up to 3 days, while the cucumbers stay crispest when prepped last minute. That means you can assemble this salad in under 15 minutes, even on busy evenings. Let’s get started!

Ingredients for jamie oliver cucumber salad

Bright, tangy ingredients that come together in 15 minutes for a crowd-pleasing summer salad.

The cucumbers are the star—Persian cucumbers stay crispest, but any variety works. Grab them from the farmers' market if possible, or the produce section at Whole Foods for the freshest. Look for ones that are firm, not wrinkled, and store them in the fridge until ready to slice. The dressing ingredients are all pantry staples, but fresh dill and high-quality olive oil make the difference between good and restaurant-worthy. I always snag the dill in bunches and chop it fresh—it keeps for 5 days in the fridge if wrapped in damp paper towels.

No Dijon mustard? Yellow mustard works in a pinch, but you’ll lose some depth. The garlic can be roasted for a sweeter flavor—just toss whole cloves in olive oil and roast at 400°F for 10 minutes. Short on feta? Skip it or use goat cheese for a tangier bite. The avocado is optional but adds creaminess—add it last so it doesn’t turn brown. For extra crunch, toss in toasted pine nuts or chopped walnuts. The dressing keeps for 3 days in the fridge, so make extra for another use.

Prep the cucumbers last minute—they soften fast once sliced. Store any leftover dressing in a sealed jar in the fridge for up to 3 days. The salad itself keeps for 2 days, but the avocado and feta will get softer over time. To reheat: toss with a splash of water and microwave for 20 seconds. This is the kind of recipe that tastes even better the next day—flavors meld beautifully.

Step-by-step instructions for Jamie Oliver's cucumber salad recipe

This bright, tangy salad comes together in minutes—crisp cucumbers meet her signature zesty dressing.

Slice the 2 whole Persian cucumbers into thin rounds—about ⅛-inch thick. I like to peel them first for a cleaner texture, but leave the peel on if you prefer a rustic look. Transfer the slices to a large mixing bowl.

While you work, slice the 1 whole avocado into ¼-inch thick pieces. Set these aside—they'll add creamy richness when we add them later. The avocado should be ripe but not mushy, so press gently before slicing to check for give.

In a small bowl, combine the 0.25 cup red wine vinegar, 1 tbsp Dijon mustard, 1 tbsp granulated sugar, 0.5 tsp sea salt, and 0.25 tsp black pepper. Whisk vigorously for about 30 seconds until the sugar dissolves completely and the mixture is smooth.

Next, add the 0.5 cup extra-virgin olive oil in a slow stream while whisking continuously. You're looking for an emulsified dressing—it should thicken slightly and look like mayonnaise when finished. If it separates, whisk in another splash of vinegar.

Mince the 3 cloves garlic cloves and add them to the dressing along with the 0.5 cup chopped fresh dill. Stir gently to combine—you want the garlic to infuse the dressing without overpowering it. Let this mixture sit for 5 minutes while you finish prepping the salad.

Here's the thing—fresh dill makes all the difference. If you're using dried dill, reduce the amount to 1 tbsp and toast it lightly in a dry pan for 30 seconds first to intensify the flavor. The dressing should smell bright and herby when you're done.

Pour the dressing over the cucumber slices and toss gently to coat evenly. Let it marinate for 10 minutes at room temperature—this allows the flavors to meld and the cucumbers to soften slightly without getting mushy. You'll know it's ready when the dressing clings to the cucumbers and they look glistening.

Just before serving, fold in the 0.5 cup crumbled feta cheese and the sliced avocado. The avocado should be added last so it stays fresh and creamy. Toss everything together one final time, being careful not to overmix so the avocado stays intact.

Let the salad sit for another 5 minutes before serving. This resting time ensures the flavors are perfectly balanced and the dressing has time to fully coat the ingredients. The cucumbers should be tender-crisp, the dressing tangy with just the right amount of sweetness, and the feta adding a salty contrast.

Serve immediately while the avocado is at its peak texture. This salad pairs beautifully with grilled meats, fresh bread, or as a standalone summer dish. The key to success is timing—don't make it too far ahead or the avocado will oxidize and turn brown.

Swap the feta for crumbled halloumi and add ¼ cup chopped Kalamata olives for a briny, salty contrast. I love using lemon-thyme olive oil instead of plain olive oil—just infuse ½ cup olive oil with 2 tbsp lemon zest and 1 tbsp fresh thyme for 10 minutes before using.
