I developed this recipe during a busy week when I needed a meal that was both nutritious and filling without requiring extensive prep.

The salad's foundation is perfectly cooked lentils and roasted beets, tossed with fresh herbs and a bright lemon-tahini dressing that ties everything together. What makes this dish special is its versatility—serve it as a hearty main course with crusty bread or as a side to complement grilled meats and fish.

The combination of flavors and textures ensures every bite is satisfying, while the nutritional benefits make it a standout choice for health-conscious meals.

By the time you assemble this salad, you'll have a dish that's as visually appealing as it is delicious—deep pink beets, earthy brown lentils, and fresh greens create a striking contrast.

The dressing adds a creamy, tangy element that enhances the natural sweetness of the beets and balances the earthiness of the lentils. This salad is perfect for meal prep, as it keeps well in the refrigerator for up to four days, making it an ideal option for busy weeknights.

The best part? This recipe is packed with fiber, plant-based protein, and essential nutrients, making it a complete meal that’s both wholesome and flavorful. Whether you're looking for a new vegan main dish or a nutrient-dense side, this beetroot lentil salad delivers on both fronts. Let's get started!

Ingredients for beetroot lentil salad

Simple, nutrient-packed ingredients that shine when roasted and tossed together.

The beets are the star here—pick medium-sized ones for even roasting. Whole Foods or Trader Joe's usually carry the pre-washed baby beets, but regular beets work too if you peel and cube them. For the lentils, green or brown work best—they hold their shape better than red. If you're short on time, pre-cooked canned lentils (rinsed well) save 20 minutes. The tahini? Look for 100% sesame paste—no additives—and store it in the fridge after opening. Walnuts are optional but add that satisfying crunch—Costco sells them in bulk for great prices.

No tahini? Substitute with extra olive oil and a splash of lemon—just skip the maple syrup. Fresh herbs missing? Dried parsley or mint at half the amount works in a pinch. The red onion adds bite, but if you're sensitive to raw onions, quick-pickle them in vinegar for 10 minutes to mellow the flavor. For the dressing, blend everything until smooth—no lumps! If it's too thick, add a splash of water. The maple syrup balances the tangy lemon perfectly, but agave or date syrup works too. Want extra protein? Add cooked chickpeas or quinoa to the mix.

This salad keeps beautifully—4-5 days in the fridge sealed in a container. The dressing separates slightly, so just give it a quick stir before serving. For meal prep, I portion mine into glass jars with dressing on the bottom—keeps everything fresh. The beets and lentils reheat well if you're making this ahead, but the arugula stays best raw. Store the walnuts separately if you're worried about them getting soggy. Freezing isn't recommended—textures suffer—but the dressing freezes well for up to 3 months if you make extra.

Step-by-step instructions for beetroot lentil salad

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

Preheat your oven to 400°F and line a baking sheet with parchment paper. Peel the 2 whole medium beets, then cut them into 1-inch cubes. Toss the beet cubes with 0.25 cup extra-virgin olive oil and 0.75 tsp salt until evenly coated.

Spread the beets in a single layer on the prepared baking sheet, leaving space between each piece for even browning. Roast for 30-35 minutes until the edges are deep golden brown and the beets can be pierced easily with a fork. The beets should be tender but still hold their shape—overcooking turns them mushy. Let them cool slightly before handling.

While the beets roast, rinse the 1 cup dried green lentils under cold water to remove any debris. In a medium saucepan, combine the lentils with 3 cups water, 0.75 tsp salt, and 0.25 tsp black pepper. Bring to a boil over high heat, then reduce the heat to medium-low and simmer uncovered for 20-25 minutes.

You'll know the lentils are done when they're tender but still hold their shape—like tiny, firm marbles. Drain any remaining water and let them cool completely before mixing with other ingredients. The lentils should be at room temperature to prevent the salad from becoming watery.

In a small bowl, whisk together the 0.25 cup tahini, 0.5 cup fresh lemon juice, 0.5 cup water, 1 tbsp maple syrup, 2 cloves minced garlic, 0.5 tsp salt, and 0.25 tsp black pepper. The dressing should be smooth but still slightly thick—if it's too thick, whisk in an additional 1-2 tablespoons of water.

Taste and adjust the balance of flavors: add more lemon juice for brightness, more maple syrup for sweetness, or more salt for depth. This dressing is the heart of the salad, so don't rush this step. The tahini will emulsify as you whisk, creating a creamy, nutty base that ties everything together.

In a large bowl, combine the cooled roasted beets, cooked lentils, 2 cups arugula, 0.5 whole red onion thinly sliced, 0.5 cup chopped toasted walnuts, 0.25 cup chopped fresh parsley, and 0.25 cup chopped fresh mint leaves. Gently toss everything together just until the arugula is wilted and the ingredients are evenly distributed.

Here's the thing—don't overmix. You want the arugula to stay vibrant and the beets and lentils to retain their texture. The salad should look colorful and inviting, with pockets of each ingredient visible. This is where the beauty of the dish comes together.

Drizzle the tahini-lemon dressing over the salad and toss gently to coat everything evenly. The dressing should cling to the lentils and beets without making the salad soggy. Taste and adjust seasoning one final time—you might need a pinch more salt or a squeeze of lemon to balance all the flavors.

Serve immediately while the arugula is still crisp and the beets are warm from roasting. This salad shines when eaten fresh, with the contrast of warm lentils and beets against the peppery arugula. Garnish with additional chopped parsley or mint if desired, and enjoy with crusty bread or as a light main course.

Best sauces and condiments for beetroot lentil salad

Tahini-Lemon Dressing

This creamy, nutty dressing is the star of your beetroot lentil salad. The tahini provides rich depth, while fresh lemon juice adds brightness that cuts through the earthy beets and lentils.

I blend 0.25 cup tahini, 0.5 cup lemon juice, 0.5 cup water, 1 tbsp maple syrup, 2 minced garlic cloves, 0.5 tsp salt, and 0.25 tsp black pepper until smooth. For extra richness, add 1 tsp olive oil at the end. 💛

Balsamic Glaze

Add a tangy-sweet contrast with a homemade balsamic glaze. Simmer 0.25 cup balsamic vinegar in a small saucepan over medium heat for 5-7 minutes until reduced by half. Let it cool, then drizzle 1 tbsp over the assembled salad.

The deep caramelized notes enhance the roasted beets beautifully. For a quicker option, use store-bought reduced balsamic from brands like Annie's.

Yogurt-Herb Sauce

For a lighter option, blend 0.5 cup plain Greek yogurt, 1 tbsp lemon juice, 1 tbsp chopped dill, 1 tsp honey, and 0.25 tsp salt. This creamy sauce adds a refreshing contrast to the hearty salad.

I like to fold it in just before serving to keep the arugula crisp. If you're vegan, use coconut yogurt instead. The herbs brighten up the earthy flavors perfectly. ✨

Spicy Harissa Dressing

For heat lovers, mix 2 tbsp harissa paste (like Bella brand), 2 tbsp tahini, 3 tbsp water, and 1 tsp lemon juice. Adjust spice level with salt or maple syrup. Drizzle over the salad and toss gently.

The smoky, spicy kick pairs wonderfully with the sweet beets and nutty lentils. Start with 1 tbsp and add more to taste—this is one of my go-to dressings for bold flavor. 🌶️

Mustard-Dijon Vinaigrette

A classic Dijon mustard vinaigrette elevates this salad effortlessly. Whisk 2 tbsp Dijon mustard, 3 tbsp olive oil, 1 tbsp lemon juice, 1 tsp maple syrup, and 0.5 tsp salt. The mustard adds a sharp, tangy note that balances the salad's richness.

For extra depth, add 1 tsp grated ginger or 1 minced shallot. This dressing keeps well in the fridge for 5 days, making it perfect for meal prep. 💡
