Lentils are a very healthy addition to your eating plan. They are high in fiber and many other nutrients with very little fat. They also have plenty of plant-based protein in them.

This recipe is simple and uses basic ingredients you can find in any grocery store. In fact, you may already have all the ingredients you need at home.

FAQs

Can I Use Different Types Of Lentils?

You can, but you’ll need to adjust the cooking time. This recipe calls for brown lentils.

Green lentils, if used, will take about 20-25 minutes longer to cook and may need more liquid as a result.

Red lentils can be used but require a shorter cooking time, so you’ll need to be sure your vegetables get cooked fully in that time. They only need about 20-25 minutes of cooking time at most, especially if they are split.

Please note that older lentils take longer to cook.

Are There Any Substitutes For The Spinach?

You can use any dark, leafy greens you prefer. Or you can omit the green completely. Your choice.

Can I Used Canned Lentils Instead Of Dried Lentils?

This should work if you cook everything else in the broth first, stirring in the lentils in the last 5 minutes of cooking just to warm them up.

Do I Need To Soak The Lentils Before Cooking Them?

You can if that’s your standard practice, but it’s not required for this recipe. Soaking may shorten the cooking time a bit, so keep an eye on it if you do.

Can I Make This In An Instant Pot Or Slow Cooker?

You could, but this is such a simple stovetop recipe that it seems kind of pointless to do that.

Can I Blend The Soup For A Smoother Texture?

You can blend the soup once everything is cooked. Blend until it reaches your desired texture.

Does This Spinach Lentil Soup Work For The Mediterranean Diet?

Yes, it does. While the flavor profile is not Mediterranean, the recipe itself fits perfectly for this style of eating.

Can I Make This Spinach Lentil Soup Spicy?

You can. Add some cayenne pepper or crushed red chili flakes to the soup with the other spices. Start small and taste to adjust.

My Soup Turned Out Too Thick. How Can I Thin It Out?

This can happen if the lentils soak up extra liquid in storage or if you cook the soup for too long, cooking down the broth. To remedy this, simply add more vegetable broth when you heat the soup.

What Kind Of Texture Does This Spinach Lentil Soup Have?

It’s a hearty, chunky soup that is soft and tender in texture.

Storage

Store leftovers in an airtight container in the fridge for up to 4 or 5 days.

Freezing

This can be frozen for up to 6 months without affecting the texture of the soup. I recommend freezing in individual portions for easy meals.

Reheating

From frozen – Thaw in the fridge for a full 24 hours, or defrost in a microwave.

From fridge – Reheat in a pot on the stove or in a microwave-safe bowl in the microwave.
