Ingredients You’ll Need
The foundation is simple: one pound of bulk Italian sausage, one diced yellow onion, sliced carrots, sliced celery, and three minced garlic cloves. Together, these ingredients create the aromatic base that carries the entire soup.
Use one cup of dried green or brown lentils. Rinse them well and pick them over before cooking, since dried lentils can occasionally contain small stones or debris; soaking is not necessary.
A 14- to 15-ounce can of diced tomatoes, including the juices, brings acidity and color. Six cups of chicken broth or stock provide enough liquid for the lentils to simmer until tender while leaving you with a spoonable soup.
For seasoning, use one teaspoon of Italian seasoning, one-half teaspoon of black pepper, and one-half teaspoon of salt, adding more salt to taste at the end. Olive oil is optional and should be used only if the sausage is very lean, while two cups of baby spinach or chopped kale can be added near the finish.
- Sausage: Mild or hot bulk Italian sausage both work well.
- Lentils: Green or brown varieties hold their shape best.
- Greens: Spinach wilts quickly, while chopped kale stays a little more substantial.
- Acidic finish: Red-wine vinegar or lemon juice adds a bright contrast.
How to Make It Step-by-Step
Step 1: Rinse the lentils under cool running water, then spread them through your fingers or inspect them in a shallow bowl. Remove any small stones, shriveled pieces, or debris, and set the cleaned lentils aside; there is no need to soak them.
Step 2: Set a large Dutch oven or soup pot over medium-high heat. Add the bulk sausage and cook for 6 to 8 minutes, breaking it into small pieces with a wooden spoon, until it is browned and cooked through; if there is a large amount of rendered fat, carefully drain the excess before continuing.
Step 3: Add the diced onion, sliced carrots, and sliced celery to the browned sausage. Cook the vegetables for about 5 minutes, stirring from time to time, until the onion starts to turn translucent and the carrots and celery begin to soften.
Step 4: Stir in the minced garlic and Italian seasoning. Let them cook for 30 to 60 seconds, just until fragrant, taking care not to let the garlic scorch on the bottom of the pot.
Step 5: Add the rinsed lentils, diced tomatoes with their juices, chicken broth, one-half teaspoon of salt, and one-half teaspoon of black pepper. Stir well, scraping up any flavorful browned bits from the bottom, and bring the liquid to a boil.
Step 6: Reduce the heat to maintain a gentle simmer and partially cover the pot. Simmer for 25 to 35 minutes, stirring occasionally, until the lentils are tender; the exact timing varies slightly with the age and type of lentils.
Step 7: If you are adding greens, stir in two cups of baby spinach or chopped kale during the final 2 to 3 minutes. Taste the soup carefully and adjust the salt and pepper before ladling it into bowls.
Chef Tips for the Best Soup
Give the sausage enough time to brown before adding broth. Browning develops deeper flavor and makes it easier to remove excess fat, so resist the urge to rush this first cooking stage.
Green and brown lentils are the best choice when you want the finished soup to have clearly defined lentil pieces. Red lentils break down much faster and create a thicker, less chunky texture, which is delicious but different from the standard version of this recipe.
Keep the pot partially covered while the lentils simmer. This helps maintain the liquid level while still allowing the soup to reduce slightly and concentrate its savory flavor.
Salt gradually rather than heavily seasoning at the beginning. Sausage and chicken broth can both vary in saltiness, so the final taste-and-adjust step is important.
For a bright finish, add a small splash of red-wine vinegar or lemon juice directly to each serving. The acidity cuts through the richness of the sausage and makes the tomato-based broth taste more lively.

Serving Suggestions
Ladle the hot soup into wide bowls so the sausage, lentils, and vegetables are easy to see in every serving. A few grinds of black pepper on top are all you need, although a small amount of chopped fresh herbs can also add color if you have them available.
Crusty bread is especially good for dipping into the broth, while garlic toast brings an extra savory note. A simple green salad makes a crisp side dish and keeps the overall dinner fresh and balanced.
If you added spinach or kale, serve the soup as soon as the greens are tender and vibrant. For a slightly brighter bowl, pass red-wine vinegar or lemon wedges at the table so everyone can adjust the acidity to taste.
This soup can be the first course of a larger dinner as well. Pair it with easy baked chicken tacos for a casual spread, or keep the soup as the main dish for a simpler weeknight meal.
Storage, Reheating, and Make-Ahead Notes
Let leftovers cool promptly, then transfer them to covered containers and refrigerate them. The lentils may continue to absorb broth as the soup rests, so the next-day texture can be a little thicker than when freshly made.
Reheat the soup gently in a saucepan over medium-low heat, stirring occasionally until it is hot throughout. If it has thickened more than you prefer, loosen it with a little additional chicken broth or stock while reheating.
When preparing the soup ahead, reserve the final salt adjustment and any vinegar or lemon juice until serving. This gives you a better opportunity to balance the broth after it has rested and lets each diner choose a brighter or more savory finish.
