Lentil & Chicken Spring Salad

The first time I made this salad, I was trying to use up leftover roasted chicken from Sunday dinner and a random bag of lentils that had been sitting in my pantry for months. It was one of those thrown together Tuesday meals that ended up surprising me completely. The peppery arugula hit against the creamy lentils, and that tangy mustard dressing tied everything together in a way that made me forget I was just cleaning out the fridge. My husband took one bite and asked me to write down exactly what I did, which never happens with my improvisations.

Last spring, I brought this to a potluck when I was running late and panicked about what to make. The bowl was empty before I even made it to the buffet line, and three people texted me afterward for the recipe. Something about the combination of warm, earthy lentils and bright, acidic dressing makes people keep coming back for seconds without realizing how healthy they are eating.

Ingredients

• 1 cup dry green or brown lentils: I have found that green lentils hold their shape better than red ones, giving you those satisfying little pops of texture instead of turning into mush
• 2 cups cooked shredded roasted chicken:Use whatever you have left over, even a store bought rotisserie chicken works beautifully here
• 4 cups fresh arugula: The peppery bite cuts through the rich dressing and adds this gorgeous contrast to the earthy lentils
• ½ cup pickled red onions:These bring this bright acidic punch that wakes up the whole bowl
• 3 tbsp extra virgin olive oil: A really good quality olive oil makes a noticeable difference in the dressing
• 1½ tbsp Dijon mustard: This creates that creamy emulsion without any mayonnaise
• 1 tbsp white wine vinegar: Adds just enough sharpness to balance the honey
• 1 tsp honey: Takes the edge off the mustard and vinegar naturally

Instructions

Cook the lentils until perfectly tender:

Place lentils in a saucepan with 3 cups water, bring to a boil, then reduce heat and simmer uncovered for 20 to 25 minutes until they are tender but still hold their shape, then drain them well

Whisk together your zesty dressing:

In a small bowl, combine olive oil, Dijon mustard, vinegar, honey, garlic, salt, and pepper, whisking until the mixture becomes thick and creamy

Combine everything in a large bowl:

Mix the cooked lentils, shredded chicken, arugula, pickled onions, cherry tomatoes, and cucumber together gently

Dress and toss the salad:

Pour the mustard dressing over the salad and toss with tongs until everything is lightly coated

Plate and enjoy:

Divide among four plates and serve right away while the arugula is still crisp

This salad has become my go to for new moms and friends recovering from surgery because it feels substantial but still so fresh and light. Something about putting real food on the table that happens to be good for you feels like an act of care.

Making It Your Own

I have swapped roasted turkey or grilled tofu for the chicken when I was cooking for vegetarians, and both worked beautifully. The lentils are really the backbone here, so as long as you keep those and that mustard dressing, you can play with almost everything else.

Timing Everything Right

The trick is letting the lentils cool just enough so they do not wilt the arugula when you toss them together, but not so much that they become cold and unappealing. I usually start the dressing while the lentils are draining, which gives them about five minutes to reach that perfect warm but not hot stage.

Serving Suggestions

Some crusty bread on the side makes this feel like a complete meal, especially if you want to soak up any extra dressing at the bottom of the bowl. I have also added crumbled feta or goat cheese when I wanted something extra creamy.

• Add a handful of fresh herbs like parsley or dill for even more brightness
• Toast some nuts like walnuts or pine nuts for crunch on top
• Keep the dressing on the side if you are packing this for lunch the next day

Every time I make this now, I think about that random Tuesday when I was just trying to clean out the fridge and ended up with something I have made dozens of times since. Sometimes the best recipes find you when you are not even looking.

Recipe FAQs

→ Can I make this ahead of time?

Yes, cook lentils and prepare dressing up to 2 days ahead. Store separately and toss with fresh ingredients just before serving to maintain texture and prevent sogginess.

→ What can I substitute for the chicken?

Roasted turkey breast works well as a direct replacement. For vegetarian options, try grilled tofu, chickpeas, or hard-boiled eggs. Adjust cooking times accordingly.

→ How do I make quick pickled onions?

Thinly slice one red onion and soak in equal parts vinegar and warm water with 1 tablespoon each sugar and salt. Let sit 30 minutes minimum, though overnight yields best results.

→ Can I use canned lentils instead?

Absolutely. Rinse and drain one 15-ounce can of lentils to replace cooked dry lentils. This reduces prep time significantly, though texture may be slightly softer.

→ How long does the dressing stay fresh?

The mustard dressing keeps refrigerated in an airtight container for up to one week. The vinegar acts as a natural preservative. Whisk briefly before using to recombine.

→ Is this salad gluten-free?

Yes, as written this dish is naturally gluten-free. Always verify packaged ingredients like Dijon mustard and pickled onions are certified gluten-free if you have severe sensitivities.
