# Hearty Lentil Soup: Best Simple Italian Seasoning Recipe - Link: https://lifeandwork.blog/italian-lentil-soup/ - Published: 2026-09-04T07:10:08-05:00 - Author: Bert Swope Hearty lentil soup is a practical Italian-inspired meal made with inexpensive ingredients, dried lentils, vegetables, herbs, and broth. It has a savory flavor, satisfying texture, and enough substance to serve as a main course. This simple Italian seasoning recipe relies on oregano, basil, thyme, rosemary, garlic, and bay leaf rather than a long list of specialized ingredients. The soup is naturally high in plant protein and fiber, and it can be prepared in one pot with modest effort.

Sauté the vegetables before adding liquid, then season with Italian herbs, garlic, and bay leaf. Simmer until the lentils are tender, then add salt and acid to taste. Store leftovers in the refrigerator for up to five days. ## Hearty Lentil Soup With Simple Italian Seasoning ### Ingredients Serves 6 * 2 tablespoons olive oil (30 mL) * 1 medium yellow onion, diced, about 1 1/2 cups (225 g) * 2 medium carrots, diced, about 1 cup (130 g) * 2 celery stalks, diced, about 1 cup (100 g) * 4 garlic cloves, minced, about 1 tablespoon (15 g) * 1 1/2 cups dried brown or green lentils (about 285 g), rinsed and picked over * 1 can diced tomatoes, 14.5 ounces (411 g), with juices * 6 cups vegetable or chicken broth (1.4 L) * 1 teaspoon dried oregano (1 g) * 1 teaspoon dried basil (1 g) * 1/2 teaspoon dried thyme (0.5 g) * 1/2 teaspoon dried rosemary (0.5 g), crushed * 1 bay leaf * 1/2 teaspoon freshly ground black pepper (1 g) * 1 teaspoon kosher salt, plus more to taste (5 g) * 2 cups chopped kale or spinach, optional (about 60 g) * 1 tablespoon lemon juice or red wine vinegar (15 mL) * Grated Parmesan cheese, optional, for serving ### Preparation 1. Warm the olive oil in a large Dutch oven or heavy pot over medium heat. Add the onion, carrots, and celery. Cook for 7 to 9 minutes, stirring occasionally, until the vegetables soften and the onion becomes translucent. 2. Add the garlic, oregano, basil, thyme, rosemary, black pepper, and salt. Stir for about 30 seconds, just until the garlic becomes fragrant. Briefly heating the herbs helps release their aroma into the oil. 3. Add the rinsed lentils, diced tomatoes, broth, and bay leaf. Stir well, then bring the mixture to a gentle boil. 4. Reduce the heat to low. Partially cover the pot and simmer for 30 to 40 minutes, stirring every 10 minutes. The lentils should be tender but not falling apart. Cooking time varies according to the lentils’ age and moisture content. 5. Remove the bay leaf. Stir in the kale or spinach, if using, and cook for 2 to 4 minutes, until the greens wilt. Add the lemon juice or red wine vinegar. Taste and adjust the salt, pepper, and acidity. 6. Ladle the soup into bowls. Add a small amount of grated Parmesan, if desired, and serve with crusty bread. ## Why This Seasoning Works ![Illustration of Hearty Lentil Soup: Best Simple Italian Seasoning Recipe](https:// i0.wp.com/lifeandwork.blog/wp-content/uploads/hearty-lentil-soup-best-simple-italian- seasoning-recipe-imag-1788094849.png?fit=1024%2C1536&ssl=1) Italian seasoning is effective in lentil soup because its herbs complement the earthy flavor of legumes without covering it. Oregano contributes a peppery, slightly bitter note. Basil adds a gentle sweetness, while thyme supplies a woodsy flavor that helps connect the vegetables and broth. Rosemary should be used in moderation because its flavor is strong and can become dominant. Garlic provides savory depth, and bay leaf adds a subtle herbal quality during cooking. Lemon juice or vinegar is added near the end because acid brightens the soup after the lentils and vegetables have simmered. Without a small acidic element, the finished dish may taste flat even when it contains enough salt. ## Choosing and Preparing Lentils Brown and green lentils are the best choices for soup because they retain their shape and produce a pleasantly thick broth. Red and yellow lentils cook faster and break down more readily. Red or yellow lentils are suitable if you prefer a smooth, porridge-like texture, but the cooking time should be reduced to about 20 to 25 minutes. Dried lentils do not require soaking. Spread them on a plate or tray before rinsing to remove small stones, damaged lentils, or other debris. Rinse them under cool water until the water runs mostly clear. This step removes dust and helps prevent excess foam during cooking. Salt can be added during the initial simmer, although some cooks prefer to add most of it near the end. Modern lentils generally soften properly in salted water, but tomatoes and acidic ingredients can slow softening. For that reason, this recipe adds tomatoes at the beginning but reserves the final adjustment of salt and acid until the lentils are tender. ## Adjustments for Texture and Flavor For a thicker soup, use the back of a spoon to crush some lentils against the side of the pot. You can also blend one or two cups of the soup and stir it back into the pot. This method thickens the broth without adding cream. For a thinner soup, add warm broth or water in 1/2-cup increments. Lentils continue absorbing liquid as they cool, so leftovers often require additional liquid when reheated. A small diced potato can replace part of the lentils or be added with them. Chopped zucchini, mushrooms, or green beans also work well. If using frozen vegetables, add them during the final 10 minutes so they retain some texture. For a richer flavor, substitute part of the broth with water and add a Parmesan rind during simmering. Remove the rind before serving. A spoonful of tomato paste, cooked with the vegetables for one minute, gives the broth a deeper tomato flavor. ## Storage and Reheating ![Additional Illustration of Hearty Lentil Soup: Best Simple Italian Seasoning Recipe]( https://i0.wp.com/lifeandwork.blog/wp-content/uploads/hearty-lentil-soup-best-simple- italian-seasoning-recipe-imag-1788094872.png?fit=1024%2C1536&ssl=1) Cool the soup promptly and place it in a covered container. Refrigerate it for up to five days. For longer storage, freeze it in individual portions for up to three months. Leave room in each container for expansion. For general guidance on preparing and storing lentil soup, see this [slow-cooker lentil soup guide](https://www.spendwithpennies.com/slow-cooker-lentil-soup/). Reheat the soup gently on the stovetop or in a microwave-safe bowl. Add broth or water as needed because the lentils thicken the soup during storage. Taste the reheated portion before serving and correct the seasoning with salt, pepper, or a few drops of lemon juice. ## Frequently Asked Questions ### Do lentils need to be soaked before making soup? No. Brown and green lentils cook well without soaking. Rinse them and remove any debris before adding them to the pot. ### Can canned lentils be used? Yes. Replace the dried lentils with about four 15-ounce cans, or 1.7 kg total, of drained and rinsed lentils. Reduce the broth to about 4 cups, or 950 mL, and simmer the soup for 20 minutes so the flavors can combine. ### Can this soup be made vegetarian? Use vegetable broth and omit Parmesan, or choose a vegetarian Parmesan-style cheese. The soup is otherwise vegetarian when prepared with olive oil and plant-based ingredients. ### Is lentil soup gluten-free? The ingredients listed are naturally gluten-free, but packaged broth and spice blends may contain gluten or be processed in facilities that handle wheat. Read the product label when a gluten-free meal is required. ### Why are my lentils still firm? Old lentils can take longer to soften. Acidic ingredients, such as tomatoes, may also extend the cooking time. Continue simmering with additional broth until the lentils are tender. If the problem persists, the lentils may be too old for a satisfactory texture. ### What should be served with hearty lentil soup? Crusty bread, a simple green salad, roasted vegetables, or a small portion of cooked rice pairs well with the soup. A spoonful of plain yogurt or grated Parmesan can provide a cool or salty contrast. ### Share this: * [ Print ](https://lifeandwork.blog/italian-lentil-soup/#print?share=print) * [More](https://lifeandwork.blog/italian-lentil-soup/#) * [[ * [Share on Tumblr](https://www.tumblr.com/share) * [ Email ](https://lifeandwork.blog/italian-lentil-soup/?subject=%5BShared%20Post%5D%20Hearty%20Lentil%20Soup%3A%20Best%20Simple%20Italian%20Seasoning%20Recipe&body=https%3A%2F%2Flifeandwork.blog%2Fitalian-lentil-soup%2F&share=email) * [Tweet](https://twitter.com/share) * [ Telegram ](https://lifeandwork.blog/italian-lentil-soup/?share=telegram) * [ WhatsApp ](https://lifeandwork.blog/italian-lentil-soup/?share=jetpack-whatsapp) * [ Reddit ](https://lifeandwork.blog/italian-lentil-soup/?share=reddit) * [ Threads ](https://lifeandwork.blog/italian-lentil-soup/?share=threads) * [ Mastodon ](https://lifeandwork.blog/italian-lentil-soup/?share=mastodon) * [ Nextdoor ](https://lifeandwork.blog/italian-lentil-soup/?share=nextdoor) * [Post](https://x.com/share) * [ Bluesky ](https://lifeandwork.blog/italian-lentil-soup/?share=bluesky) ### _Related_
