Heat 3 tablespoon extra virgin olive oil until shimmering but not smoking. Add onions, carrots and garlic. Cook 3 to 4 minutes, stirring regularly. Add spices and bay leaves. Cook for a few seconds till fragrant, keep stirring so spices don't burn.
Add crushed tomatoes, broth, lentils. Season
with kosher salt. Bring to a boil, then lower heat to simmer for 15 to 20 minutes, until lentils are fully cooked.
Remove from heat. If you have the time, let soup cool a bit before using an immersion blender to puree. Pulse a few times till you reach the creamy consitency you are looking for.
Return soup to heat, and stir to warm through. Add lemon zest, lemon juice, and fresh parsley.
Transfer soup to serving bowls.
