2 tbsp olive oil For sautéing aromatics.

1 large onion, diced Yellow or white works fine.

2 carrots, sliced Adds natural sweetness.

2 celery stalks, diced Provides aromatic depth.

3 garlic cloves, minced Or 1 tsp garlic powder.

6 cups low‑sodium vegetable broth Can use chicken broth if preferred.

3 cups fresh spinach, packed Baby spinach works best.

½ cup Greek yogurt (plain) For creaminess; optional.

1 tsp smoked paprika Adds subtle warmth.

Salt & pepper to taste Adjust after simmering.

Instructions

Sauté the aromatics

Heat olive oil in a large pot over medium heat. Add diced onion, carrot, and celery. Cook, stirring occasionally, until vegetables soften and the onion becomes translucent, about 5‑6 minutes. Add minced garlic and smoked paprika; sauté another minute until fragrant.

Pro Tip: Do not brown the garlic; it turns bitter quickly.

Add lentils and broth

Stir in the rinsed green lentils, then pour in the low‑sodium vegetable broth. Increase heat to bring the mixture to a gentle boil, then reduce to a simmer. Cover partially and let cook for 20‑25 minutes, or until lentils are tender but still hold shape.

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

Incorporate spinach

Add the packed spinach leaves to the pot. Stir continuously; the leaves will wilt quickly, about 2‑3 minutes. This step preserves the bright green color and maximizes nutrient retention.

Pro Tip: If using frozen spinach, thaw and squeeze out excess water first.

Finish with yogurt

Remove the pot from heat. Temper the Greek yogurt by whisking a ladle of hot soup into it, then stir the mixture back into the pot. This prevents curdling and creates a silky finish. Season with salt and pepper to taste.

Pro Tip: For a dairy‑free version, substitute with a plant‑based yogurt.

Serve or store

Ladle the soup into bowls, garnish with a drizzle of olive oil or extra yogurt if desired. Cool completely before transferring to airtight containers. Refrigerate up to 4 days or freeze for up to 3 months; reheat gently on the stovetop.

Pro Tip: Reheat only once to maintain texture.

Expert Tips

Tip #1: Toast the lentils

Dry‑toast lentils for 2 minutes before adding broth; this deepens their nutty flavor without extra fat.

Tip #2: Adjust thickness

If you prefer a thicker soup, blend half of it with an immersion blender, then stir back in.

Tip #3: Spice it up

Add a pinch of cayenne or a dash of hot sauce at the end for a warming kick on cold days.

Storage & Variations

Store the soup in glass jars; it keeps 4 days in the fridge and 3 months frozen. For a heartier version, stir in cooked quinoa or barley before serving. To make it vegan, replace Greek yogurt with coconut yogurt and add a splash of lemon juice for brightness.

Frequently Asked Questions

Yes. Use a no‑salt‑added broth and season with herbs, lemon juice, or a splash of vinegar instead of extra salt. The smoked paprika still provides depth without sodium.
