Lentil Soup Ingredients

How Do You Make Lentil Soup From Scratch?

• Reduce the heat to low, cover and simmer until the lentils become tender. Remove from the heat and season to taste. Stir in the lemon juice.
• To make the soup creamier without the use of any cream, you can puree some of the soup using an immersion blender, or using a regular blender, blend about 2 cups of the soup until smooth. Return the pureed soup to the pot and stir to combine. If the soup is too thick, add additional broth until it reaches your desired consistency.

Is Eating Lentil Soup Good For You?

The answer is absolutely yes! Lentils are healthy, nutritious and a great source of plant protein, fiber, vitamins and minerals. Lentils are naturally gluten-free and low in calories.

What Type Of Lentils Is Best For Lentils Soup?

You can make homemade lentil soup with any type of lentils, but for this lentil soup recipe I prefer using dry brown or green lentils. Green and brown lentils have a mild, hearty and earthy flavor and although they hold their shape, brown lentils tend to be a bit creamy as a few always seem to break apart just a bit. Red lentils break apart easily and become mushy if cooked for more than 15 minutes. French lentils are great in salads and side dishes as they hold their shape and are firmer.

Storing

This soup recipe will keep in the refrigerator for 4-5 days in an airtight container. Cool the soup completely before storing it.

Freezing

You can freeze lentil soup for up to 3 months. Store the soup in a freezer safe container or resealable bag. I like to store the soup in smaller individual portions for convenience.

Reheating

Place the soup in a pot and reheat over medium-low heat until warm through. If the soup seems too thick, add a little bit of broth. Smaller portions can be reheated in the microwave.

Frozen lentil soup should be thaw out in the refrigerator overnight.
