Can you freeze lentil soup? Yes! This easy, one-pot, hearty lentil soup can be made in large batches and frozen in freezer bags, ice-cube trays, or freezer-safe containers. If you have picky eaters in your family, this Freezer-Friendly Lentil Soup Recipe will be a hit for sure! Feel free to sneak in extra vegetables like kale, tomatoes, and celery so you can be sure that they are getting all the nutrients.
Heat oil in a large pot over medium heat.
Add garlic and the onions and cook for about 2 minutes.
Add the celery and carrots and cook until softened and the onion starts to caramelize. This should take about 7-10 minutes.
Add lentils, tomatoes, and stock to the bot, bringing everything to a boil. Lower the heat to medium-low and let the mixture simmer for about 20 minutes.
Add all remaining ingredients (cumin, coriander, bay leaves) except lemon and salt, stir, and cover the pot with a lid. Leave for about 20 minutes or so, until the lentils get soft but not mushy.
Using an immersion blender or a stick blender, do 2 or 3 quick whizzes to thicken the soup. You can also transfer 2 cups of cooled soup to a blender, blend, then transfer it back to the pot. Feel free to add water or more stock if you want to adjust the soup consistency.
Check the flavors and season to taste with salt and pepper.
Add the zest of a lemon and add a squeeze of lemon juice and garnish with finely chopped kale.
