Instructions

Prep the vegetables

Dice carrots, parsnip, sweet potato, and onion into uniform ½‑inch pieces. Mince garlic. Rinse lentils under cold water, discarding any debris. This uniform size ensures even cooking and a consistent texture throughout the soup.

Pro Tip: If you’re short on time, use pre‑cut frozen root veg; just add them directly to the pot.

Sauté aromatics

Heat olive oil in a large pot over medium heat. Add onion and garlic, stirring until translucent and fragrant, about 3‑4 minutes. This step builds the flavor foundation without burning the garlic.

Pro Tip: Keep the heat moderate; a splash of water prevents sticking.

Add liquids and lentils

Stir in the rinsed lentils, vegetable broth, thyme, and bay leaves. Increase heat to bring the mixture to a rolling boil, then reduce to a gentle simmer. This initial boil activates the lentils’ starches for a creamy texture.

Pro Tip: Skim any foam that rises to keep the broth clear.

Simmer with root vegetables

Add carrots, parsnip, sweet potato, and onion to the pot. Cover and simmer for 30‑35 minutes, stirring occasionally, until lentils are tender and vegetables are soft but not mushy. The broth will naturally thicken.

Pro Tip: For a smoother texture, blend half the soup and return to the pot.

Finish and store

Remove bay leaves, stir in apple cider vinegar, and season with sea salt to taste. Let the soup cool to room temperature before transferring to airtight containers. Refrigerate up to 5 days or freeze for up to 3 months.

Pro Tip: Reheat gently; avoid boiling to preserve the fresh herb aroma.

Expert Tips

Tip #1: Toast the lentils

Dry‑toast lentils in the pot for 2 minutes before adding liquid; this adds a nutty depth without extra ingredients.

Tip #2: Use low‑sodium broth

Controlling salt early lets you finish with a precise flavor balance and keeps the soup heart‑healthy.

Tip #3: Add greens at the end

A handful of spinach or kale tossed in just before serving boosts nutrients without overcooking the leaves.

Tip #4: Adjust thickness

If the soup is too thick, stir in a splash of water or extra broth; if too thin, simmer uncovered for 5‑10 minutes.

Storage & Variations

Cool the soup completely before sealing; it keeps 5 days in the fridge and 3 months frozen. For a spicy twist, stir in a pinch of cayenne or a dash of hot sauce. Swap lentils for chickpeas or add a swirl of coconut milk for a creamy, dairy‑free version.

Frequently Asked Questions

Red lentils cook faster and break down more, giving a creamier texture. If you use them, reduce the simmer time to 20‑25 minutes and add them after the broth reaches a boil.

The recipe is already vegan; just ensure the vegetable broth contains no animal products. For extra richness, stir in a tablespoon of nutritional yeast or a splash of coconut milk at the end.

Yes. Freeze in airtight containers once cooled. When reheating, add a little extra broth or water to restore the original consistency, as lentils may absorb some liquid during storage.
