Ingredients for beetroot lentil salad

Earthy beets and protein-rich lentils meet vibrant herbs and citrus for a restaurant-quality salad.

The beets are the heart of this dish—golden or red varieties work equally well, but golden roasts slightly faster. Whole Foods Market and Trader Joe's carry pre-washed baby beets, which save time, but regular beets from the produce section are just as good. Look for firm, vibrant beets with smooth skins; avoid any with soft spots or wilted leaves. For the lentils, French green lentils hold their shape beautifully, but brown or beluga lentils also work. Rinse them well before cooking to remove any debris, and don't skip the thorough rinsing—it makes a noticeable difference in texture. The tahini should be 100% sesame paste with no additives; Kirkland Signature or Soom Tahini are reliable brands.

No tahini? Substitute with a mix of olive oil and a pinch of garlic powder, though the flavor won't be identical. Fresh herbs can be swapped—cilantro or dill work well if you're out of parsley or mint, but the brightness changes slightly. For the dressing, apple cider vinegar can replace red wine vinegar, though it adds a slightly different tang. If you're using dried herbs, reduce the amount to one-third of what's called for in fresh form. The walnuts can be omitted if you're avoiding nuts, but the salad will lose some of its satisfying crunch. For extra protein, add avocado slices or chickpeas—both pair beautifully with the earthy flavors.

The roasted beets and cooked lentils keep well in the fridge for 5 days when stored separately in airtight containers. Assemble the salad just before serving to maintain crispness in the greens. The dressing can be made up to 3 days in advance and stored in a sealed jar in the refrigerator. If you're prepping for meal prep, store the components separately and toss with dressing just before eating. The walnuts stay fresh for 2 weeks in a sealed container, but toasting them fresh adds an extra layer of flavor. For a make-ahead option, roast the beets and cook the lentils a day ahead—they reheat beautifully and taste even better after flavors meld.

Step-by-step instructions for beetroot lentil salad

This vibrant salad balances earthy roasted beets with protein-rich lentils and bright tahini dressing.

Preheat your oven to 400°F. Toss the 2 whole medium beets (peeled and cubed) with 1 tablespoon of the extra-virgin olive oil until evenly coated. Spread them on a baking sheet in a single layer, ensuring they don't overlap. Roast for 25-30 minutes until tender when pierced with a fork and developing a caramelized exterior.

Here's the thing—don't cut corners on roasting time. Undercooked beets will taste raw and gritty, while overcooked ones turn mushy. You'll know they're done when they yield easily to gentle pressure and have developed a rich, deep color. Let them cool completely before assembling the salad—this prevents the dressing from turning watery.

In a medium saucepan, combine the 1 cup French green lentils with 3 cups water and bring to a boil. Reduce heat to medium-low and simmer for 20-25 minutes until the lentils are tender but still hold their shape. Drain any remaining water and transfer them to a bowl to cool slightly.

The key to perfect lentils is maintaining their texture. Overcooking turns them mushy, while undercooking leaves them chalky. You want them firm enough to hold their shape but still tender enough to eat. Once cooled, they'll absorb the dressing beautifully, creating a cohesive salad texture.

In a small bowl, whisk together the 0.33 cup tahini, 2 tablespoons red wine vinegar, 2 tablespoons fresh lemon juice, 1 tablespoon maple syrup, and 1.5 teaspoons diamond crystal kosher salt. Slowly drizzle in the remaining 2 tablespoons extra-virgin olive oil while continuing to whisk until the dressing is smooth and emulsified.

This dressing is the heart of your salad—don't rush the emulsification. The tahini can be thick, so take your time incorporating the oil. If it separates, simply whisk vigorously to recombine. The balance of sweet maple syrup, tangy vinegar, and nutty tahini creates a complex flavor that complements the earthy beets and lentils perfectly.

In a large bowl, combine the 4 cups fresh baby spinach, roasted beets, cooked lentils, 0.5 cup thinly sliced red onion, and 0.5 cup toasted walnuts. Pour the tahini dressing over the top and toss gently but thoroughly to coat all ingredients evenly. Fold in the 0.25 cup chopped fresh parsley and 0.2 cup chopped fresh mint leaves just before serving to preserve their vibrant colors.

The order of assembly matters here. Adding the herbs last keeps their bright flavors and colors intact. Tossing gently ensures the spinach remains wilted but not broken down. Let the salad sit for 10 minutes before serving to allow all the flavors to meld together—this is when the magic happens.

Flavor customization for beetroot lentil salad

Sweet & Tangy Twist

Swap the maple syrup for 1 tbsp honey or agave nectar and add 1 tsp grated fresh ginger to the dressing for a zesty kick. The ginger brightens the earthy beets while the honey deepens the caramel notes.

I love this variation when serving with spicy dishes—it balances heat beautifully. 🌶️

Smoky Chipotle Heat

Infuse the dressing with smoky depth by adding ½ tsp adobo sauce (from canned chipotles) or ¼ tsp smoked paprika. This works especially well with golden beets, as the smokiness complements their natural sweetness.

For extra heat, add ½ tsp cayenne pepper—just be mindful of spice sensitivity in your group.

Citrusy Zest Boost

Double the lemon juice to 4 tbsp and add zest from 1 lemon for a brighter, more vibrant flavor profile. The zest adds aromatic complexity that pairs wonderfully with the mint.

For a tropical twist, substitute 1 tbsp lime juice and ½ tsp lime zest instead. The acidity cuts through the richness of the tahini perfectly.

Creamy Avocado Addition

Add 1 ripe avocado, diced, to the salad just before serving for a luscious, creamy texture. The healthy fats from the avocado enhance the tahini dressing while adding a buttery contrast to the earthy beets.

For extra richness, mash ½ avocado into the dressing instead of using some of the tahini. 🥑

Herb Swap Variations

Replace the parsley and mint with ¼ cup chopped dill for a fresh, slightly bitter note that works beautifully with the beets. For a Mediterranean flair, use 2 tbsp chopped oregano and 2 tbsp chopped basil.

The oregano adds an earthy depth, while basil brings a sweet, aromatic brightness. Experiment with combinations—your taste buds will thank you!

Spiced Walnut Crunch

Toast the walnuts with ½ tsp cinnamon and ¼ tsp cayenne for a warm, slightly spicy crunch. This works especially well with the sweet-tangy dressing and adds a cozy, autumnal quality to the salad.

For a sweeter touch, toss the toasted walnuts with 1 tsp maple syrup while they cool—they'll caramelize slightly for extra flavor. 🍂
