How to Make Lentil Soup

Heat the oil: In a large pot over medium heat, warm the extra-virgin olive oil until shimmering. This will create a rich base for your soup.

Lentil Soup Recipe FAQs

How do I select the best lentils for making Lentil Soup?
Absolutely! For lentil soup, I recommend using dry green or brown lentils as they maintain their shape and texture beautifully. Avoid canned lentils, as they can lead to a mushy consistency. When choosing, look for lentils that are whole and free of debris or dark spots.

How should I store leftover Lentil Soup?
Very! Ensure you store your leftover lentil soup in airtight containers in the fridge. It will stay fresh for up to 4 days. Let the soup cool completely before sealing the containers to preserve its flavor and texture.

Can I freeze Lentil Soup and how?
Of course! You can freeze your lentil soup for up to 3 months. To do this, allow the soup to cool completely, then transfer it into airtight containers or freezer bags. If using freezer bags, lay them flat for easier storage. When you’re ready to enjoy it, thaw overnight in the fridge before reheating.

What should I do if my soup is too thick after cooking?
No worries! If you find your lentil soup has thickened more than you’d like, simply add a splash of vegetable broth or water, then stir well over medium-low heat until it reaches your desired consistency.

Are there any dietary considerations I should be aware of?
Absolutely! This lentil soup is naturally vegan and gluten-free, making it a fantastic option for those with dietary restrictions. However, always check your seasonings and broth to ensure they meet your specific needs. It’s also wise to inform guests if you’ve included optional ingredients like grated Parmesan or spice toppings, as these can be common allergens.

How can I enhance the flavors of my Lentil Soup?
The more the merrier! To elevate the flavor of your lentil soup, consider adding a bay leaf during simmering, or experiment with additional herbs such as rosemary or basil. You can also adjust the spices based on your taste preference—adding more cumin or even a hint of smoked paprika can add a great depth of flavor.
