Instructions
Step 1) - First of all, to make Italian lentil soup recipe, start by preparing the vegetables. Wash and peel the carrot and celery. Peel the onion. On a cutting board make small pieces of carrot, celery and onion. Finally peel and cut the potatoes into cubes, not too small. Otherwise they will split during cooking.
Step 2) - Pour the oil into a high-sided saucepan. Add the vegetables and a peeled clove of garlic. Sauté over medium heat for about 3 minutes.
Step 3) - Add the chopped potatoes. Stir and cook for 3-4 minutes. Then add the lentils. If you soaked the lentils, drain them well from the water. If not, rinse them quickly and add them to the vegetables and stir.
Step 4) - Then cover the lentils with the hot vegetable broth, about 1 liter of broth.
Step 5) - Add a bay leaf, a twig of rosemary, a spoonful of tomato paste and a drizzle of extra virgin olive oil.

Tips
- SOAKING THE LENTILS: Most commonly used are dried lentils. Best cooking instructions can usually be found on the package. Unlike other legumes, lentils do not always require soaking before cooking. Typically, larger lentils are soaked overnight (about 6-8 hours). Small lentils (such as the Castelluccio di Norcia lentils that we used in our recipe) do not need to be soaked in water.
- RINSE: Dried lentils, whether sold loose or unopened in their package, are still a product of the earth. For this reason, even if you choose not to soak them, you should rinse them thoroughly before use. They may even contain some pebbles or soil residue. This way you will avoid any nasty surprises under your teeth!
- HULLED LENTILS: These types of lentils are sold to us "hulled", that is, with the skins removed. They are mainly small, red or orange lentils that have had their skins removed mechanically. This process makes them more digestible, quicker to cook and suitable for those with digestive problems. This type of lentil is NOT suitable for soups, but is ideal for velvety creams and meatballs.
- CANNED LENTILS: Canned lentils do not require soaking because they are precooked and stored in their own water. They are ready to use.
- ADDING SALT: You may have noticed that we suggest adding salt only at the end of cooking. This tip is very important. Salt prevents the lentils from reaching a tender texture. If you salt too soon, you risk finding the legumes hard and raw under your teeth or having to prolong the cooking time by a lot.
- LENTIL QUALITY: Another tip is not to mix different qualities of lentils. They differ in color and size and also in texture. Each one has different cooking times and liquid absorption capacity. This would result in a soup with unevenly cooked lentils. Some still hard and some possibly overcooked.
Variations
Italian lentil soup is a one-pot dish, traditional to Mediterranean cuisine. We have shown you the classic version of lentil soup, the completely vegetarian one. For an even lighter soup, you can omit the addition of potatoes.
Like many dishes of traditional Italian cucina povera, there are many variations.
- VEGETABLES: We can add as many vegetables as we want, such as fresh spinach, diced squash, or mushrooms. The important thing is that the lentils remain the protagonists, both in terms of taste and quantity.
- CHILI PEPPER: For a touch of spiciness we can add a chopped chili pepper to the soffritto.
- PORK RIND: In ancient traditional recipes it was customary to add pork rind to the legume soup to give it more flavor and substance.
- PANCETTA: We can also add diced pancetta to the soffritto. Your lentil soup will be even more irresistible!
- HAM SHANK: In Tuscany it's customary to add pieces of ham shank.
- PARMIGIANO CHEESE: To make the soup even tastier, we can also add a generous sprinkling of grated Parmigiano cheese to the soup already on the plate.
- PASTA OR RICE: You can also add small pasta, usually tubetti or ditalini, or rice. You can do it in two ways. Cook the pasta or rice together with the lentils, adding them about halfway through cooking. In this case you will need to keep the lentil soup much more runny. Or you can boil and drain the pasta or rice separately and then add them to the soup. Pasta and Lentils or Rice and Lentils are traditional classic dishes of ancient Italian cucina povera.
