The Secret Ingredient: Unlocking Unforgettable Flavor with Pasta Sauce
What if we told you the secret to this soup’s incredible depth of flavor lies in an unexpected pantry staple? Yes, it’s pasta sauce! When creating this recipe, I found myself without standard canned tomato products, but plenty of ready-made pasta sauce jars. A chunky Marinara sauce was my first choice, and the result was nothing short of spectacular. The rich blend of tomatoes, herbs, and sometimes even a hint of sweetness or spice in a quality pasta sauce provides an immediate, complex flavor base that would otherwise take hours to develop from scratch.
This clever hack saves time and elevates the soup’s profile significantly. Imagine the robust flavor of slow-cooked Italian herbs and ripe tomatoes, all integrated seamlessly into your lentil soup. The second time I made it, I used a roasted garlic pasta sauce, and it was equally divine, adding another layer of aromatic complexity. Feel free to experiment with your favorite type of pasta sauce – be it a classic marinara, a spicy arrabbiata, or a creamy tomato-based sauce – to personalize your soup’s character.
Choosing Your Sausage: Flavor, Texture, and Versatility
For this Italian Lentil Sausage Soup, I highly recommend using Aidells Italian Chicken Sausage. We adore their rich, smoky flavor and the fact that they’re made from chicken, offering a lighter alternative without compromising on the hearty, satisfying taste. These sausages are pre-cooked and smoked, which means they infuse the soup with a wonderful depth quickly, requiring less cooking time than raw sausage. Their Italian seasoning perfectly complements the tomato and lentil base, creating a cohesive and mouth-watering experience.
However, the beauty of this recipe lies in its adaptability. If you prefer, you can easily substitute the chicken sausage with your favorite pork sausage (mild or spicy Italian), or even a plant-based sausage for a vegetarian-friendly option. If opting for raw pork sausage, ensure it’s fully cooked and browned before adding other ingredients to develop maximum flavor and proper texture. For a completely meat-free version, simply omit the sausage – the soup remains incredibly flavorful and hearty thanks to the lentils and rich broth, making it a fantastic vegetarian lentil soup.
Mastering the Seasoning: A Pinch of Perfection
Seasoning is key to any great soup, and this Italian Lentil Sausage Soup is no exception. Given that ingredients like sausage, broth, and especially prepared pasta sauce can vary significantly in their sodium content, it’s crucial to adjust your salt levels carefully. I always recommend starting with just 1/2 teaspoon of kosher salt while sautéing the vegetables. This allows you to build flavor without over-salting early on.
Once the lentils are nearly cooked and the soup has simmered for a while, taste it! This is your moment to adjust. Add more salt, a dash more pepper, or even a pinch of red pepper flakes for a subtle kick, if desired. Only when you’re satisfied with the seasoning should you add the spinach. This iterative approach ensures your soup is perfectly balanced and bursting with flavor, tailored to your preference.
Versatile Cooking: Stove Top & Instant Pot Options
Whether you prefer the classic, steady simmer of a stove-top pot or the speed and convenience of an Instant Pot, this lentil and sausage soup recipe is designed to work beautifully both ways. The original recipe provides detailed instructions for stove-top cooking, emphasizing the traditional method of building layers of flavor. However, recognizing the popularity of modern kitchen appliances, we’ve also included comprehensive Instant Pot instructions to make this delicious soup accessible to everyone, no matter their preferred cooking style.
While the overall flavor profile remains consistent, the Instant Pot offers a quicker cooking time, making it ideal for busy weeknights. The stove-top method, on the other hand, allows for a more hands-on approach, letting you savor the aromas as they develop. Both methods yield a wonderfully hearty and flavorful soup that will warm you from the inside out.
Serving Suggestions & Pairings for Your Italian Lentil Sausage Soup
This hearty Italian Lentil Sausage Soup is a meal in itself, but a few thoughtful accompaniments can elevate it to an extraordinary dining experience. For a truly authentic touch, serve it with generous slices of crusty Italian bread or a warm baguette, perfect for soaking up every last drop of the rich broth. A sprinkle of freshly grated Parmesan or Pecorino Romano cheese adds a salty, umami finish that beautifully complements the soup’s robust flavors.
Consider pairing it with a simple, crisp side salad dressed with a light vinaigrette to cut through the richness. For a complete Italian-inspired meal, a glass of medium-bodied red wine, such as a Chianti or Sangiovese, would be a delightful pairing. Don’t forget a fresh garnish! A scattering of fresh parsley or basil can add a pop of color and a fresh herbaceous note right before serving.

Pin Recipe
Equipment
-
Dutch Oven or large heavy-bottomed pot
-
Instant Pot (for pressure cooking method)
Ingredients
- 2 links Aidells Italian Chicken Sausage chopped into bite-sized pieces; can substitute with pork sausage or vegetarian sausage.
- 6 cups chicken or vegetable broth preferably low sodium, allowing for better salt control.
- 1 large carrot peeled and finely diced for quick cooking and even texture.
- 2 stalks celery diced, contributing to the aromatic base.
- 1/2 large onion, white or yellow diced, a foundational flavor for many soups.
- 1 cup dried lentils, French sorted and rinsed thoroughly to remove any debris; French lentils hold their shape well.
- 1/2 jar prepared, chunky pasta sauce approximately 1 1/4 cups; this is our secret ingredient for depth and richness.
- 2 cups spinach frozen, or equivalent fresh spinach; adds nutrients and vibrant color.
- 1/2 tsp thyme dried, a classic herb that pairs wonderfully with lentils and tomatoes.
- 1/2 tsp salt, kosher start with this amount and adjust to taste; see notes for guidance.
- 1/2 tsp pepper freshly ground black pepper for best flavor.
- 2 leaves bay adds a subtle, aromatic depth; remember to remove before serving.
- 2 cloves garlic minced or chopped, essential for Italian flavor.
- 1-2 tbsp olive oil for sautéing vegetables.
Instructions
Stove top
-
In a large Dutch oven or heavy-bottomed pot, heat 1 tablespoon of olive oil over medium heat. Add more if needed to coat the bottom of the pot.
-
Add the diced carrots, celery, and onion to the hot oil. Sauté for about 5-7 minutes, stirring occasionally, until the vegetables begin to soften and the onion becomes translucent. Stir in the minced garlic, kosher salt, and black pepper, and cook for another minute until fragrant.
-
Pour in the chicken broth, add the chopped sausage, dried thyme, sorted and rinsed lentils, bay leaves, and the chunky pasta sauce. Stir everything together to combine.
-
Bring the soup to a gentle boil, then reduce the heat to low, cover, and let it simmer for approximately 30 minutes. During this time, the lentils should become tender but still hold their shape. Before adding the spinach, taste the soup and adjust the seasoning as needed, adding more salt or pepper if desired. Remember to consider the sodium content of your broth, sausage, and pasta sauce.
-
Stir in the frozen spinach. Continue to cook for another 5 to 10 minutes, or until the spinach is fully wilted and the lentils are perfectly tender. Remove the bay leaves before serving.
Instant pot
-
Combine all ingredients (chopped sausage, chicken broth, diced carrots, celery, onion, minced garlic, lentils, pasta sauce, thyme, salt, pepper, and bay leaves) into the Instant Pot insert. Stir well to ensure everything is evenly distributed.
-
Secure the lid on the Instant Pot and ensure the sealing valve is set to the “Sealing” position. Select the “Soup/Broth” setting and set the cooking time to 12 minutes on high pressure.
-
Once the cooking cycle is complete, carefully perform a manual (quick) release of the pressure by turning the sealing valve to “Venting.” Stand clear of the steam.
-
After all the steam has been released and the float valve has dropped, indicating it’s safe to open, remove the lid. Add the frozen spinach to the hot soup.
-
Replace the lid (no need to seal again) and let the soup sit for about 5 minutes. The residual heat will effectively wilt the frozen spinach. If using fresh spinach, simply stir it in until it wilts, which will happen almost instantly. Remove the bay leaves before serving.
-
Serve hot, topped with grated Parmesan cheese and a side of crusty bread for dipping. Enjoy your quick and hearty Instant Pot Italian Lentil Sausage Soup!
Notes
Salt Adjustment: Always taste and adjust salt at the end. Different brands of broth, sausage, and pasta sauce contain varying amounts of sodium, so starting low and adding more as needed prevents an overly salty soup.
Lentil Varieties: While French lentils are recommended for their ability to hold shape, you can use brown or green lentils. Red lentils tend to break down and become mushy, altering the texture of the soup.
Vegetarian Option: For a delicious vegetarian lentil soup, simply omit the chicken sausage and use vegetable broth. You can also add more vegetables like diced zucchini or chopped kale for extra bulk and nutrition.
Spicy Kick: If you enjoy a bit of heat, add a pinch of red pepper flakes along with the other seasonings.
Storage: Leftover soup can be stored in an airtight container in the refrigerator for up to 3-4 days. It also freezes well for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stove or in the microwave.

Tips for Success & Creative Variations
To ensure your Italian Lentil Sausage Soup is consistently amazing, here are a few extra tips and ideas for customization:
Enhancing Flavor and Texture:
- Herbs & Spices: Don’t limit yourself to just thyme. A pinch of dried oregano or Italian seasoning can further boost the “Italian” profile. For a fresher taste, stir in fresh basil or parsley at the very end.
- Umami Boost: A teaspoon of balsamic vinegar or a squeeze of lemon juice stirred in just before serving can brighten all the flavors.
- Creaminess: For a richer, creamier soup, stir in a splash of heavy cream, coconut milk (for a dairy-free option), or a swirl of plain Greek yogurt after cooking.
- Adding Vegetables: This soup is incredibly forgiving. Feel free to add other quick-cooking vegetables like diced bell peppers, zucchini, or even a handful of chopped kale or Swiss chard along with the spinach.
Making it Your Own:
- Spicier Version: If you love heat, add a pinch of red pepper flakes with the garlic, or use a spicy Italian sausage.
- Different Proteins: Experiment with different types of sausage, such as turkey sausage for a leaner option, or even ground beef or turkey that’s browned and crumbled. For a vegetarian version, consider adding a can of drained and rinsed chickpeas for extra protein.
- Broth Variations: While chicken or vegetable broth is standard, you could use beef broth for a deeper, more robust flavor if using pork or beef sausage.
