Ingredients Needed to Make Lentil Soup (Italian Vegetable)

To make this delicious and hearty Lentil Soup (Italian Vegetable), you’ll need a mix of pantry staples, fresh produce, and a few flavor boosters that come together for that irresistible Italian flair. Below is a breakdown of each ingredient, why it matters, and how to make smart swaps if you’re short on something. Whether you’re making this soup for the first time or batch cooking it for the week, these Lentil Soup ingredients are the building blocks of a soul-warming meal.

• Olive Oil – 2 tablespoons
  This is where the magic begins. A couple of tablespoons of extra virgin olive oil gives the base of your soup a silky, rich start. It helps caramelize the onions and carrots just enough to pull out their natural sweetness. If you’re looking to try other dishes that start with this flavorful base, check out our Creamy Mushroom Chicken Soup for another warm, oil-sautéed favorite.
• Carrots – 1½ cups, diced (about 3 medium carrots)
  Carrots add color, crunch, and a gentle sweetness that balances the acidity from the tomatoes. Dice them small so they soften properly and distribute evenly in every spoonful. Bonus? Carrots are packed with vitamin A, which makes this Lentil Soup not just comforting, but also nourishing.
• Yellow Onion – 1½ cups, diced (1 medium onion)
  You really can’t skip the onion. It’s the aromatic foundation that brings the entire Lentil Soup (Italian Vegetable) together. Yellow onions are best for this recipe thanks to their mellow, slightly sweet flavor that deepens as they cook.
• Garlic – 1½ tablespoons, minced (about 4 cloves)
  Garlic adds that bold, unmistakably Italian flavor we all crave. Don’t skimp here. Minced garlic infuses the soup with a warm, savory backbone that complements the herbs and lentils beautifully. Pro tip: sauté it just until fragrant to avoid bitterness.
• Vegetable Broth – 4 cans (14.5 oz each)
  This is the liquid gold that brings everything together. Vegetable broth keeps the soup vegetarian and adds layers of depth. If you’re not strictly plant-based, you can use chicken broth for a more robust flavor. Either way, it’s the key to creating a comforting broth that lets the lentils shine.

• Diced Tomatoes – 2 cans (14.5 oz each)
  Canned diced tomatoes add acidity, color, and body. They help break down and meld with the broth to create that signature Italian-style tomato base. If you like a chunkier soup, keep them as-is. Prefer smoother? Give them a quick pulse in the blender before adding.
• Brown Lentils – 1¼ cups, rinsed and picked over
  These little gems are the star of the show. Brown lentils are hearty, protein-rich, and hold their shape well during cooking—perfect for this rustic Italian soup. Be sure to rinse and check them for small stones (yes, it happens!). Looking for another veggie-rich soup with hearty ingredients? Our German Cabbage Soup is another great meatless option.
• Dried Basil – 1½ teaspoons
  Basil brings that sweet, earthy Italian flavor you love in pasta sauce right into your soup bowl. If you’re using fresh basil instead, toss it in at the end of cooking for the best flavor.
• Dried Oregano – ½ teaspoon
  Oregano adds depth with just a touch of bitterness and a peppery edge that balances the soup’s sweetness. It’s subtle but essential to rounding out those classic Italian flavors.
• Dried Thyme – ½ teaspoon
  Thyme offers an herbaceous note that elevates everything around it. It’s like background music for your soup—quiet, but you’d miss it if it weren’t there.
• Salt & Freshly Ground Black Pepper – to taste
  Seasoning is key. Lentils absorb flavor as they cook, so taste your soup as it simmers and adjust the salt and pepper along the way. Don’t wait until the end—layer it in.
• Zucchini – 1½ cups, diced (1 medium zucchini)
  This soft, slightly sweet squash rounds out the veggie lineup and adds a delicate texture. Add it toward the end so it doesn’t overcook. For another recipe that uses zucchini beautifully, check out our Italian Chicken and Autumn Veggie Soup.
• Kale or Spinach – 2 cups packed, chopped
  A good Lentil Soup needs a leafy green for both color and nutrition. Kale holds up well if you’re making the soup ahead, while spinach wilts beautifully if you’re serving it right away. Just be sure to add spinach in the final minutes of cooking to avoid over-softening it.
• Fresh Lemon Juice – 1 tablespoon
  It may seem like a tiny detail, but lemon juice is what brightens the entire dish. Just a tablespoon added at the end lifts the earthy lentils and makes the flavors pop. It’s that “hmm, what is that?” ingredient that keeps people coming back for another bowl.
• Parmesan Cheese – Optional, for serving
  Shaved, shredded, or grated—Parmesan cheese adds a salty, umami-rich finish that melts beautifully over the top of a warm bowl. It’s optional, but if you’re not dairy-free, highly recommended. You could even pair this with our cheesy Hamburger Noodle Soup if you’re in a hearty comfort food mood.

These ingredients work together to create a warm, balanced Lentil Soup (Italian Vegetable) that’s both satisfying and good for you. And the beauty of it? Most of these are kitchen staples, which means you’re probably already halfway to a pot of homemade comfort. Ready to get cooking?

Instructions to Make Lentil Soup (Italian Vegetable)

Making Lentil Soup (Italian Vegetable) is incredibly simple when you follow this step-by-step guide. Whether you’re new to soup-making or just want a dependable recipe, these directions walk you through each stage in a way that’s easy to follow — and leaves plenty of room for personal flair. We’ll also highlight helpful kitchen tips and connect you to related recipes and preparation tricks along the way, so you feel supported from the first chop to the final spoonful.

Let’s get cooking — step by step!

Step 1: Sauté the Aromatics

Start by heating 2 tablespoons of olive oil in a large heavy-bottomed pot or Dutch oven over medium-high heat. Once the oil shimmers (but isn’t smoking), add 1½ cups of diced carrots and 1½ cups of diced yellow onions.

Cook these for about 2 minutes, stirring occasionally, until the onions start to soften and turn translucent. Then stir in 1½ tablespoons of minced garlic (about 4 cloves) and cook for another 2 minutes, just until the garlic is fragrant.

Tip: Don’t let the garlic brown—it can turn bitter fast. Want more garlic tips? Visit our guide on common flavor boosters that add depth to soups and stews.

Step 2: Add the Broth, Tomatoes, and Lentils

Pour in 4 cans (14.5 oz each) of vegetable broth and 2 cans of diced tomatoes (also 14.5 oz each), juice and all. Stir to combine.

Next, add 1¼ cups of rinsed brown lentils, along with 1½ teaspoons of dried basil, ½ teaspoon oregano, and ½ teaspoon thyme. Season with salt and freshly ground pepper to taste.

Bring everything to a gentle boil, then reduce the heat to medium-low and cover the pot.

Step by step tip: If you don’t have each dried herb individually, you can substitute 1 tablespoon of Italian seasoning—it works just as well and saves time. See our full substitution guide for more quick swaps.

Step 3: Simmer and Let the Flavors Develop

Now comes the “let it do its thing” phase.

Let the soup simmer for 35 minutes, covered. Stir occasionally to prevent the lentils from sticking to the bottom. During this time, the lentils will begin to soften and soak up all that tomato-herb goodness.

Step 4: Add the Vegetables

Once the lentils are tender but not mushy, stir in 1½ cups of diced zucchini and 2 cups of chopped kale or spinach.

Let the soup simmer for another 10 minutes if you’re using kale—it needs a little more time to soften. If you’re going with spinach, stir it in during the last 2 minutes of cooking so it just wilts without overcooking.

Step 5: Add Freshness and Adjust Consistency

Once the veggies are tender, stir in 1 tablespoon of fresh lemon juice. This small step adds a bright, zesty kick that elevates the whole dish.

As the soup cools, the lentils will continue to absorb liquid, thickening the broth. If it’s looking too thick, add up to 1 cup of water or more vegetable broth to reach your desired consistency.

Pro tip: Let the soup sit for 10 minutes off the heat before serving—it gives the flavors time to mingle. Looking for more brothy goodness? You’ll love our Hamburger Rice Soup Recipe too.

Step 6: Serve and Customize

Ladle the finished Lentil Soup (Italian Vegetable) into warm bowls. If you’re feeling fancy, top with a sprinkle of parmesan cheese or a drizzle of extra virgin olive oil.

Serve with crusty Italian bread or homemade garlic toast to soak up every last drop. Want something extra comforting on the side? Try pairing this with our crowd-favorite Chicken Pot Pie Soup.

What to Serve with Lentil Soup (Italian Vegetable)

A big bowl of Lentil Soup (Italian Vegetable) is a meal all on its own, but if you want to level it up, serve it with some crusty Italian bread or a slice of garlic toast for dipping. A simple green salad with balsamic vinaigrette balances the warmth with a fresh crunch. For a heartier combo, try it alongside a grilled cheese (pro move: use mozzarella and basil).

Key Tips for Making Lentil Soup (Italian Vegetable)

• Stick with brown or green lentils. Red lentils cook too fast and turn mushy.
• Don’t skip the lemon juice. It might seem small, but it adds that pop of freshness.
• No veggie broth? Chicken broth works too.
• Chop your veggies evenly. This helps them cook at the same rate (and makes it look pretty).
• Use what you have. Sub kale for spinach, or add celery, sweet potatoes, or even leftover green beans.

Storage and Reheating Tips for Lentil Soup (Italian Vegetable)

This soup stores like a dream. Let it cool, then pop it into airtight containers. It keeps in the fridge for up to 5 days and freezes well for up to 3 months. To reheat, just pour it into a pot and warm it over medium heat, stirring occasionally. If it’s too thick (because lentils love to soak up liquid), add a splash of broth or water until it’s just right. Microwave? Totally fine—heat it in 1-minute intervals, stirring in between.

FAQs

Q: Can I use red lentils instead of brown?
A: Red lentils cook much faster and break down into a mushier texture. You can use them, but reduce the simmer time and expect a thicker soup.

Q: Can I make this in a slow cooker?
A: Absolutely. Sauté the onions, garlic, and carrots first, then toss everything into the slow cooker. Cook on low for 6–7 hours or high for 3–4.

Q: Is this soup vegan?
A: Yep—just skip the parmesan or use a dairy-free version.

Q: Can I freeze it?
A: 100%. Freeze in individual portions for easy grab-and-reheat lunches.

Q: What if I don’t have kale?
A: Spinach, chard, or even finely chopped cabbage work just fine.
