Key Ingredients

Cucumbers – Choose firm, fresh cucumbers and slice them thinly so they stay crisp and soak up the dressing just enough without becoming soggy.
Pickled mustard seeds – These small, tangy bursts add a gentle heat and bright acidity, taking the salad from ordinary to extraordinary.
Red onion – Thinly sliced to add a mild bite that balances the sweetness and acidity of the dressing.
Fresh herbs – Dill or parsley adds a fragrant, herbaceous note that lifts the flavors of the salad beautifully.
Olive oil – A light drizzle of extra virgin olive oil enriches the salad and binds the dressing to the cucumber slices.
White wine vinegar – Provides a gentle acidity that balances the sweetness of the cucumbers and complements the pickled mustard seeds.

Prepare the Ingredients: Wash the cucumbers, then slice them thinly using a sharp knife or mandoline for even, delicate slices. Peel and thinly slice the red onion, then add it to the cucumber for a subtle, slightly sweet bite.

Make the dressing: In a small bowl, whisk together olive oil, white wine vinegar, a pinch of salt, and freshly ground black pepper. Taste and adjust the acidity or seasoning as needed. In a large bowl, gently toss the cucumber and onion slices with the dressing until evenly coated.

Finish with the Toppings – Sprinkle the pickled mustard seeds over the salad, ensuring each bite has a pop of tangy flavor. Chop fresh dill or parsley and sprinkle over the top just before serving for brightness and color. Find the recipe for pickled mustard seeds here.

Let it rest: Allow the salad to sit for 10–15 minutes to let the flavors meld, or serve immediately for maximum crunch.

From my Kitchen (Chef’s Notes)

Thin slicing is key: Using a mandoline or very sharp knife ensures even slices that absorb the dressing evenly while staying crisp.
Pickled mustard seeds: These can be store-bought or made at home; they add a unique texture and subtle heat that elevates the salad.
Balance flavors: Taste as you go—adjust the vinegar, salt, or a pinch of sugar to find the perfect balance between tangy, sweet, and savory.
Serving suggestions: This salad pairs beautifully with grilled meats, smoked fish, sandwiches, or as a bright side on any plate.
Make ahead: You can prepare this salad a few hours in advance; the cucumbers may soften slightly but will still retain plenty of crunch and flavor.
