Tomato Lentil Soup

You're looking at one of our favorite vegetarian soup recipes.

The flavor is rich and dreamy, with a hint of smokiness from the paprika and an umami bomb from the Manzanilla olives.

Tender lentils make this soup hearty enough to call dinner.

We usually like to serve soup with a slice of buttered bread on the side, but this one is so rich and filling that it makes a meal all on its own.

Why we love European olives

The Manzanilla olives we use in this recipe are stuffed with pimientos, buttery soft, and have the most beautiful, delicate flavor.

They're also incredibly versatile and we love snacking on them as much as we love cooking with them. It's a good thing they're so healthy!

Did you know that in Canada, one out of every two olives eaten comes from Spain, including these Manzanilla olives used in this tomato lentil soup recipe?

How to make tomato lentil soup

  1. Sauté minced onion, garlic, celery, and carrots until they begin to caramelize.
  2. Add the spices to the veggies and cook them for a moment to bring out their flavor.
  3. Add the lentils, stock, and canned diced tomatoes to the pot and simmer until the lentils are nice and soft.
  4. Now stir in a little cream, some spinach, and the best part, chopped Manzanilla olives.
