Sun-Dried Tomato Lentil Salad with Red Onion and Fresh Herbs

Lentil salad with sun-dried tomatoes, red onion, and fresh herbs—a savory, satisfying dish that’s easy to make and loved by many.

I favor Le Puy lentils for salads because they hold their shape and don’t turn mushy while cooking. When preparing a lentil salad, look for a variety that keeps a firm texture after boiling.

Don’t worry that the red onion will dominate the salad. Letting thinly sliced onion sit with vinegar softens it and mellows its bite, bringing out a subtle sweetness that complements the other ingredients.

Use delicious sun-dried tomatoes.

Choose dry-packed sun-dried tomatoes rather than ones already preserved in oil. Dry-packed tomatoes will absorb a dressing more readily and develop better flavor when soaked briefly in olive oil and balsamic vinegar. Start soaking them early so they plump and take on the marinade.

If time permits: make sun-dried tomatoes at home

If you prefer to make your own, oven-dried Roma tomatoes are simple to prepare:

  • Preheat the oven to 275°F. Quarter fresh Roma tomatoes.
  • Arrange the quarters skin-side down on a parchment-lined baking sheet.
  • Drizzle with a couple tablespoons of olive oil and two tablespoons of balsamic vinegar, and sprinkle generously with salt.
  • Roast for about 1–1½ hours, until they are semi-dry but still slightly tender.
  • Let cool before using in the lentil salad.

This salad is nutrient-dense and hearty—serve it as a main with steamed rice or roasted vegetables for a fully vegan meal, or as a side to roast meats.

Helpful tips for ingredients

Le Puy lentils: Small, grey-green lentils that keep their texture and don’t require soaking.

Sun-dried tomatoes: Buy vacuum-packed or dry-packed tomatoes (whole or sliced) and rehydrate them in olive oil and balsamic before adding to the salad.

Balsamic vinegar: Adds balanced sweetness and helps mellow the red onion’s acidity.

Red wine vinegar: A good alternative for a sharper tang that pairs well with lentils.

Red onion: Choose firm, unbruised onions and slice very thinly for quick pickling with vinegar.

Maldon sea salt: Flaky finishing salt gives texture—use in place of regular table salt for a better mouthfeel.

Fresh herbs: Parsley, chives, and dill bring brightness and depth. Avoid substituting dried herbs if you want the freshest flavor.

Garlic: Crushed garlic releases essential oils and works beautifully with balsamic.

Olive oil: Use a light, mild olive oil so it doesn’t overpower the other flavors.

Equipment

A few useful tools make preparation easier:

  • Sharp knife for chopping tomatoes and herbs.
  • Mandoline or very sharp knife for thinly slicing red onion.
  • Small bowls for marinating the sun-dried tomatoes and onions.
  • Large bowl for tossing and serving the salad.

Cooking tips

This recipe is made in two parts: cooking the lentils and preparing the dressing/marinades so the ingredients infuse with flavor.

  • Slice the sun-dried tomatoes into large pieces and mix them with balsamic, olive oil, and salt. Let them sit while you prepare the rest so they soften and absorb flavor.
  • Very thinly slice the red onion, toss with red wine vinegar and salt, and let it rest to mellow and soften.
  • Cook the lentils in boiling water for 20–30 minutes until tender but still firm. Drain well and transfer while warm to the bowl with the marinated onions. Add olive oil, crushed garlic, and pepper, then let cool slightly.
  • Chop the herbs while the lentils cook, then toss everything together once the lentils have cooled a bit so the herbs retain their freshness.

Pro tips

  • Avoid overcooking the lentils; they should be tender but not mushy to keep the salad’s texture.
  • This salad stores well and is ideal for meal prep—assemble or toss the components just before serving for best texture.

Storage

Store the salad in the refrigerator; it keeps well and the flavors often deepen after resting overnight. Bring to room temperature before serving for best flavor.

Variations and substitutions

Customize the salad by adding thinly sliced red bell pepper, lemon zest, or pitted green olives. Swap parsley for finely chopped mint for a brighter note, or add crumbled feta and a splash of lemon for a non-vegan variation that’s equally delicious.

Serve the salad as a side to roasted or grilled chicken for a complete meal.

Using leftover herbs

To extend the life of fresh herbs, wash and dry them thoroughly, then store in a sealed jar once dry. You can also chop and mix them with salt and pepper to make an easy rub or seasoning blend.
