Lentil Salad with Mustard Vinaigrette (Printable)

Hearty lentils paired with fresh tomatoes, cucumber, and a tangy mustard dressing for a nutritious bite.

# What Goes In:

→ Lentils

01 - 1 cup dried green or brown lentils, rinsed
02 - 3 cups water
03 - 1 bay leaf
04 - ½ teaspoon salt

→ Vegetables

05 - 1 cup cherry tomatoes, halved
06 - 1 cup cucumber, diced
07 - ¼ cup red onion, finely chopped
08 - ¼ cup fresh parsley, chopped

→ Mustard Vinaigrette

09 - 3 tablespoons extra virgin olive oil
10 - 1½ tablespoons red wine vinegar
11 - 1 teaspoon Dijon mustard
12 - 1 teaspoon honey or maple syrup (optional)
13 - 1 small garlic clove, minced
14 - ¼ teaspoon salt
15 - ¼ teaspoon black pepper

# How to Make It:

01 - Combine lentils, water, bay leaf, and ½ teaspoon salt in a saucepan. Bring to a boil, then reduce heat and simmer uncovered for 20 to 25 minutes until lentils are tender yet firm. Drain, discard bay leaf, and let cool to room temperature.
02 - In a large bowl, mix the cooled lentils with halved cherry tomatoes, diced cucumber, finely chopped red onion, and chopped parsley.
03 - Whisk together olive oil, red wine vinegar, Dijon mustard, honey or maple syrup if using, minced garlic, salt, and black pepper in a small bowl or jar until emulsified.
04 - Pour the vinaigrette over the lentil and vegetable mixture. Toss gently to coat evenly. Taste and adjust seasoning if necessary.
05 - Refrigerate the salad for 15 to 30 minutes to develop flavors. Serve chilled or at room temperature.

# Expert Advice:

01 -
  • It tastes even better the next day when the vinaigrette has settled into every lentil.
  • You can make it on Sunday and eat from it all week without getting bored.
  • It's genuinely filling enough to be the main event, not just a side dish.
02 -
  • Don't oversalt the cooking water or the salad will taste briny—the vinaigrette adds its own salt, which is something I learned by accident the first time.
  • If the salad tastes flat after sitting, it's never the lentils; it's always just missing one more pinch of salt or a squeeze more vinegar, so taste before you serve.
03 -
  • Cook your lentils the day before and keep them separate from the vegetables; this way you can assemble the salad fresh each morning if you want maximum crispness.
  • Make the vinaigrette in a jar so you can shake it back together if the oil and vinegar separate—there's something satisfying about that vigorous moment right before you pour.
