Why This Beetroot and Lentil Salad Just Works

Basic Ingredients, Big Flavor

Here’s the thing about lentils: they’re humble, but they pull serious weight. With around 18 grams of protein per cup, they’re one of the best meat-free ways to actually stay full. Now pair that with roasted beets sweet, earthy, and packed with antioxidants and you’ve got a combo that doesn’t just hit the nutrition checklist it genuinely tastes incredible.

But let’s be honest the real magic is in the mustard vinaigrette. It’s tangy, sharp, and just sweet enough thanks to a splash of maple syrup. That brightness cuts right through the heartiness of the lentils and wakes up the beets in the best way. When I’m meal-prepping for the week, I’ll usually roast extra beets while tossing together something like my cucumber chickpea salad it’s all part of the flow, and everything ends up tasting like it belongs on the same table.

Ingredients You’ll Need

Here’s what goes into the bowl. It’s simple, clean, and totally flexible.

For the Salad:

• 3 medium beets, roasted and diced
• 1 ½ cups cooked green or French lentils (about ¾ cup dry)
• ½ red onion, thinly sliced
• ¼ cup chopped parsley
• ¼ cup chopped fresh mint (optional)
• ⅓ cup crumbled vegan feta (optional)

How to Make Beetroot and Lentil Salad (Step by Step)

1. Roast the Beets
Preheat your oven to 400°F (200°C). Wrap each beet in foil and roast on a baking tray for 45–60 minutes until tender when pierced. Let them cool, peel, and dice.

2. Cook the Lentils
Rinse lentils under cold water, then simmer in a pot of salted water for about 20–25 minutes. They should be tender but not mushy. Drain and cool.

3. Whisk the Dressing
In a small bowl, whisk together mustard, vinegar, maple syrup, olive oil, salt, and pepper until smooth and creamy.

4. Toss the Salad
Combine lentils, beets, red onion, parsley, and mint in a large mixing bowl. Pour over the dressing and toss gently.

5. Add the Feta
If using vegan feta, fold it in or sprinkle on top just before serving.

6. Chill or Serve
You can eat it right away, but it tastes even better after chilling for at least 30 minutes. Store any leftovers in the fridge for up to 4 days.

Variations & Flavor Twists

Get Creative with Add-Ins
This salad plays well with others. Try tossing in:

• Toasted walnuts or sunflower seeds for crunch

• Shaved fennel or cucumber for fresh crunch
• Avocado slices or tahini drizzle for creaminess

Switch Up the Dressing
Feeling bold? Try a tahini lemon dressing instead. Or add cumin or smoked paprika for a warm, earthy kick. You can even thin the mustard vinaigrette with a splash of water and stir in tahini for something creamy and clingy.

These small swaps give your beetroot and lentil salad a new feel every time. That’s why it never gets boring.
