After a long day, nothing comforts you like a bowl of steaming soup that’s both nourishing and quick to make.

The recipe stays in a single pot, so cleanup is minimal, and the flavors deepen as they simmer together. Perfect for a wholesome supper, it delivers protein, fiber, and a burst of green goodness without any fuss.

4 cups vegetable broth Low‑sodium for better control of salt.
2 cups fresh spinach Baby spinach works best; roughly chopped.
1 medium onion, diced Adds sweetness and body.
3 cloves garlic, minced Fresh garlic gives the soup its aromatic heart.
2 tbsp olive oil For sautéing aromatics; can substitute avocado oil.
1 tsp dried thyme Earthy note; fresh thyme works too.
2 tbsp fresh parsley, chopped Adds brightness at the end.
1 tbsp lemon juice Finishes the soup with a fresh pop.
Salt & pepper to taste Season gradually; broth may already contain salt.

Instructions

1

Sauté aromatics

Heat olive oil in a large pot over medium heat. Add diced onion and cook 4‑5 minutes until translucent. Stir in minced garlic and thyme; cook another minute until fragrant, careful not to brown.

Pro Tip: Keep the heat moderate to avoid burning garlic, which can turn bitter.
2

Add lentils & broth

Stir in the rinsed red lentils, then pour in the vegetable broth. Increase heat to bring the mixture to a gentle boil, then reduce to a simmer, stirring once to prevent sticking.

Pro Tip: Skim any foam that rises; it keeps the broth clear.
3

Simmer the soup

Cover partially and let the lentils cook for 15‑20 minutes, or until they break down and the broth thickens. Stir occasionally; the soup should have a creamy texture without being dry.

Pro Tip: If the soup becomes too thick, add a splash of water or extra broth.
4

Add spinach & herbs

Fold in the fresh spinach and chopped parsley. Cook 2‑3 minutes, just until the leaves wilt and integrate. Taste and adjust salt and pepper as needed.

Pro Tip: Adding herbs at the end preserves their bright flavor.
5

Finish & serve

Stir in lemon juice for a fresh lift. Ladle the soup into bowls, drizzle a drizzle of olive oil if desired, and serve hot with crusty bread.

Pro Tip: A pinch of smoked paprika on top adds a subtle smoky aroma.

Expert Tips

Tip #1: Rinse lentils

Rinsing removes dust and excess starch, preventing the soup from turning gummy and ensuring a clean, silky texture.

Tip #2: Control thickness

If you prefer a thinner broth, add extra broth or water during simmering; for a heartier stew, let it reduce uncovered.

Tip #3: Make ahead

Cool the soup completely, store in airtight containers, and refrigerate up to four days; reheat gently, adding a splash of broth if needed.

Frequently Asked Questions
