Ingredients for beetroot lentil salad

Simple, vibrant ingredients that pack protein and earthy sweetness for a salad that lasts.

The beets are the star here—look for medium-sized ones with deep red color, not green shoulders. Whole Foods or Trader Joe's usually carry the pre-washed, ready-to-roast kind, which saves time. If you're buying whole beets, scrub them well and roast until fork-tender. Green lentils are ideal—they hold shape better than brown—but any dry lentils work. Bob's Red Mill or store-brand organic are both great choices. Toast the walnuts in a dry pan for 3-4 minutes until fragrant—they add incredible crunch that keeps for days.

No red wine vinegar? Apple cider vinegar works just as well. Short on maple syrup? Agave nectar or date syrup are perfect swaps. The garlic can be roasted with the beets for a sweeter flavor—just toss it in the roasting pan with the beets and olive oil. For extra protein, add cooked quinoa or chickpeas. If you're prepping ahead, roast the beets and cook the lentils a day in advance—they actually taste better after flavors meld. The parsley is optional but adds freshness; dried works at one-third the amount if you're in a pinch.

Store roasted beets and cooked lentils separately in airtight containers for up to 5 days. The walnuts stay crisp for 1 week if kept in a sealed container. Assemble the salad right before serving to keep those crunchy textures. This keeps beautifully for 4 days in the fridge—perfect for meal prep. Portion into containers with the dressing on the side if you're taking it to work, so the greens stay crisp.

Step-by-step instructions for beetroot lentil salad

Here's how to assemble this vibrant, protein-rich salad with perfectly roasted beets and tender lentils.

Preheat your oven to 400°F. Scrub the 2 whole medium beets clean, leaving the skins on, then wrap each tightly in aluminum foil. Place them directly on the oven rack or on a baking sheet.

Roast for 45-50 minutes until completely tender when pierced with a fork. The skins should be soft enough to peel easily with your fingers. Let them cool slightly before peeling—this makes the skins slip right off. Cut into ½-inch cubes and set aside.

In a medium saucepan, combine the 1 cup dry green lentils with the 2.5 cups water and bring to a boil over medium-high heat. Reduce heat to medium-low and simmer for 20-25 minutes until the lentils are tender but still hold their shape.

Drain any remaining liquid through a fine-mesh strainer and rinse the lentils under cold water to stop the cooking process. Spread them on a baking sheet to cool completely before assembling the salad. This prevents them from becoming mushy when mixed with other ingredients.

In a small bowl, whisk together the 0.5 cup extra-virgin olive oil, 0.25 cup red wine vinegar, 0.25 cup fresh lemon juice, 1 tbsp maple syrup, 1.5 tsp diamond crystal kosher salt, and 0.5 tsp freshly ground black pepper. Add the 2 minced garlic cloves and mix until fully combined.

Taste and adjust the balance of sweetness, acidity, and saltiness. The dressing should coat the back of a spoon but still allow you to see through it slightly. Let it sit for 5 minutes to allow the flavors to meld before using.

In a large mixing bowl, combine the cooled roasted beets, cooked lentils, thinly sliced red onion, and 0.5 cup toasted walnuts. Gently fold everything together until evenly distributed. The texture should be a mix of tender beets, firm lentils, and crunchy walnuts.

Drizzle the dressing over the salad and toss gently to coat all ingredients evenly. Add the 0.25 cup chopped fresh parsley just before serving to maintain its vibrant color and fresh flavor. Let the salad sit for 10 minutes before serving to allow the flavors to meld together.

Divide the salad among 4 serving plates, garnishing each with an additional sprinkle of chopped parsley and a few extra toasted walnuts for visual appeal. Serve immediately while the beets are still warm from roasting and the lentils maintain their perfect texture.

This salad pairs beautifully with grilled proteins or as a standalone meal. The earthy sweetness of the beets complements the hearty lentils, while the tangy dressing and crunchy walnuts add texture and depth to every bite.

Perfect pairings for beetroot lentil salad

Crunchy Add-Ons

Toasted walnuts add a satisfying crunch that balances the tender lentils and beets. For extra texture, try pumpkin seeds or pecans—both toast beautifully in a dry pan for 3-4 minutes until fragrant. I like toasting them right before assembling the salad to keep them crisp. 🥜

Protein Boosters

This salad is already packed with 18g protein per serving from the lentils, but you can boost it further. Add ½ cup cooked quinoa for a nutty, gluten-free grain or ½ cup chickpeas for extra fiber.

For a smoky twist, toss in ¼ cup crumbled tempeh after pan-frying it with a pinch of smoked paprika.

Garnish Game-Changers

Fresh herbs elevate this salad instantly. Beyond parsley, try chopped dill for a bright, tangy note or thinly sliced radishes for a peppery crunch. A sprinkle of everything bagel seasoning adds a savory kick, while toasted sesame seeds bring an Asian-inspired depth.

I often add pickled red onions for a tangy contrast that cuts through the richness.

Bread Pairings

Serve this salad alongside crusty sourdough or warm naan to soak up the dressing. For a heartier option, try garlic focaccia or rosemary flatbread. The crusty texture contrasts perfectly with the soft lentils and beets. I love pairing it with whole-grain crackers for a lighter, portable option.

Dessert Contrast

Balance the earthy flavors with a sweet finish. A scoop of vanilla bean ice cream or lemon sorbet cools the palate after each bite. For a lighter option, serve with honey-drizzled figs or dark chocolate-covered strawberries. The natural sweetness of the beets makes this pairing surprisingly harmonious. 🍓

Beverage Pairings

A crisp sparkling rosé or dry Riesling complements the salad’s acidity and sweetness. For non-alcoholic options, try iced hibiscus tea or sparkling water with a splash of pomegranate juice. The effervescence cleanses the palate between bites, enhancing the salad’s vibrant flavors.
