The Best Lentil Soup
Lentil and spinach soup recipe with green lentils, diced tomatoes and lots of Parmesan cheese I got from my Italian neighbour back in 2014 and improved upon with a few spices.
This healthy soup is cheap, easy and fast weeknight dinner or all weekend lunch + dinner (make once, eat five times – I am good at that).
Are Lentils Good for You?
With about 30% of their calories from protein, green lentils have the third-highest level of protein of any legume or nut, after soybeans and hemp. Lentils are also full of fiber, folate, vitamin B1 and a good source of iron. They help lower cholesterol levels and reduce the risk of heart disease. Their soluble fiber traps carbohydrates and stabilizes blood sugar levels – an example how complex carbs are healthy vs. simple carbs.
Lentils are also low in calories and dare me to say help with weight loss. 1 cup contains 230 calories but leaves you full and satisfied for long.
Lentil and Spinach Soup Ingredients
- Green lentils – Both brown and green lentils retain their shape well, so consistency of the soup won’t change. You can use red lentils but because they are split, they tend to almost disintegrate in the soup.
- Diced tomatoes – Low sodium are the best. You can also use tomato sauce.
- Veggies – Onion, carrot and celery.
- Spices and low sodium vegetable broth
- Fresh or frozen spinach – We buy 3 boxes at a time and freeze 2. Once you add spinach to hot soup it wilts right away anyways.
FAQ About Lentils
- Are lentils same as beans? Lentils are legumes just like beans but are relatively quick and easy to prepare. That’s why you rarely see canned lentils in stores.
- Do I need to soak lentils? No, just like you don’t have to soak split peas, just FYI. It is a good idea to rinse lentils and then they should take about 30 minutes to cook. Other than that lentils do not require soaking like beans which makes them convenient for quick night vegetarian meals like green lentil curry.

How to Make Lentil Spinach Soup
Full recipe card is located below.
- Sauté veggies with spices until veggies are translucent and spices fragrant.
- Add lentils and sauté for another 3 minutes, stirring here and there.
- Add liquids and spices and cook for 30 minutes or until lentils are tender.
- Add spinach and garnishes: It is enough to let fresh or frozen spinach wilt in hot soup in order “to cook” it.
- Serve hot: Garnished with Parmesan cheese and a side of baby kale salad or crustless spinach quiche for a full meal.
How to Store and Freeze
Storing soup leftovers: Lentil soup will stay fresh for up to 5 days in the fridge. Reheat desired amount by simmering on low in a small pot.
Freezing soup leftovers: Lentil soup freezes beautifully. I usually transfer leftovers to a large glass container leaving some room for soup to expand, and freeze for up to 3 months.
Thawing lentil soup: To thaw, just remove frozen soup from the freezer the night before and defrost in the fridge overnight. Chances are it still will be somewhat frozen after 24 hours, so I put it on a counter for a few hours. And if I remove soup from the freezer in the morning and would like to reheat for lunch, I just thaw it on the counter. It won’t spoil.
