Author Notes

French green lentils and black lentils hold up well to long, slow cooking without becoming mushy. Save the rinds from used-up blocks of Parmesan in a resealable plastic bag or tightly sealed container in the refrigerator. They give broth for soups a rich, savory flavor.

1 Very disappointing recipe. Even after 8 hours in slow cooker on low and 2 hours in instant pot on high, the ingredients are not integrated - it's like a salty broth with unappealing dark lumps of veggies.

I was so excited to make this soup, but unfortunately it fell flat. Lack of depth in flavor and after cooking for several hours, the beautiful vibrant vegetables were quite dull.

Simple to make, but yields amazing depth of flavor. Recommend using veg stock for added depth.
