Prepare the Ingredients
Wash all vegetables thoroughly.
Dice the onion, carrots, celery, zucchini, and bell pepper into similar-sized pieces so they cook evenly.
Rinse the lentils under cold running water until the water runs clear.
Inspect them for any small stones or debris before cooking.
Sauté the Vegetables
Heat olive oil in a large soup pot over medium heat.
Add the onion, carrots, and celery.
Cook for about 5–6 minutes until softened.
Stir in the garlic and cook for another minute until fragrant.
Next, add the zucchini and bell pepper.
Cook for an additional 3–4 minutes.
The vegetables should begin to soften while maintaining a bit of texture.
Add the Seasonings
Sprinkle in the thyme, oregano, paprika, salt, and black pepper.
Add the bay leaf.
Stir everything together for about one minute.
Cooking the herbs briefly helps release their natural aromas and deepens the soup’s flavor.
Add the Lentils
Pour the rinsed lentils into the pot.
Stir them together with the vegetables.
Add the canned diced tomatoes along with their juices.
Pour in the vegetable broth.
Mix everything well.
Increase the heat until the soup begins to boil.
Once boiling, reduce the heat to low.
Cover the pot and let it simmer gently for about 35–40 minutes.
The lentils should become tender while still holding their shape.
Finish the Soup
Once the lentils are fully cooked, stir in the fresh spinach.
Cook for another 2–3 minutes until wilted.
Remove the bay leaf.
Squeeze in the fresh lemon juice.
Taste and adjust seasoning if needed.
The lemon juice brightens the flavors and balances the richness of the soup.

Tips for the Best Lentil Vegetable Soup
Rinse Lentils Well
Always rinse dried lentils before cooking to remove dust and debris.
Don’t Overcook
Overcooked lentils become mushy.
Check for tenderness after 35 minutes.
Cut Vegetables Evenly
Uniform pieces ensure even cooking.
Add Spinach Last
Fresh spinach only needs a few minutes to wilt.
Adding it too early causes it to lose color and nutrients.
Finish with Lemon
A squeeze of lemon transforms the soup by adding freshness and enhancing every ingredient.
