Why You’ll Love Sausage and Lentil Soup Recipe
This soup delivers plenty of flavor without requiring complicated preparation. Browning the Italian sausage first creates a savory foundation, while sautéed leeks, celery, carrots, mushrooms, and red pepper add layers of flavor and texture.
Lentils make the soup filling and substantial, and spinach adds freshness without overpowering the other ingredients. The combination of oregano, parsley, crushed red pepper, and black pepper gives the broth a warm, gently spiced finish.
It’s also an easy one-pot recipe. Everything comes together in a Dutch oven, which means fewer dishes and a straightforward cooking process. Better still, the leftovers reheat beautifully, making this soup ideal for meal prep.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
- 2 lbs sweet Italian sausage
- 2 leeks, chopped
- 2 celery stalks, chopped
- 2 medium carrots, chopped
- 5 oz baby bella mushrooms
- 10 cups chicken broth
- 1/4 cup tomato paste
- 1 red pepper, chopped
- 1 cup lentils
- 4 oz spinach
- Juice of 1/2 lemon
- 2 bay leaves
- 1 tsp salt
- 1 tsp oregano
- 1 tsp parsley
- 1/2 tsp crushed red pepper
- 1/2 tsp black pepper
- 2 tbsp olive oil
Directions
1. Brown the Sausage
Place a large Dutch oven over medium-high heat. Add the sweet Italian sausage and allow it to sear undisturbed for 2–3 minutes. Break the sausage into smaller pieces and continue cooking for about 5 minutes, or until browned.
Use a slotted spoon to transfer the browned sausage to a plate and set it aside. Leave the flavorful browned bits in the pot.
2. Sauté the Leeks and Celery
Reduce the heat to medium and add the olive oil. Stir in the chopped celery and leeks. Sauté for about 5 minutes, stirring occasionally, until the vegetables begin to soften.
Add the oregano, parsley, black pepper, and crushed red pepper. Stir until the vegetables are evenly coated with the seasonings.
3. Add the Remaining Vegetables
Stir in the baby bella mushrooms, carrots, and chopped red pepper. Continue sautéing for approximately 5 minutes, or until the mushrooms begin to brown and the vegetables start to soften.
4. Caramelize the Tomato Paste
Add the tomato paste and stir thoroughly to coat the vegetables. Allow the mixture to cook for about 3 minutes. Cooking the tomato paste directly in the pot helps deepen its flavor and adds richness to the finished broth.
5. Add the Broth and Sausage
Pour in the chicken broth and add the bay leaves. Bring the soup to a boil, then reduce the heat to maintain a gentle simmer.
Return the browned sausage to the Dutch oven and simmer for 15 minutes.
6. Cook the Lentils
Stir the lentils into the soup. Continue simmering for approximately 25 minutes, or until the lentils are tender. Cooking time can vary slightly depending on the type and age of the lentils, so check them toward the end of the cooking time.
7. Finish With Spinach and Lemon
Stir in the spinach, cover the Dutch oven, and allow it to cook for about 3 minutes, just until wilted.
Remove the lid and discard the bay leaves. Stir in the fresh lemon juice. Taste the soup and adjust the salt or pepper as needed before serving hot.
Servings and timing
Servings: 8
Prep time: Approximately 15 minutes
Cook time: Approximately 45 minutes
Total time: 1 hour
This recipe makes a large pot of soup suitable for about eight servings. The exact cooking time may vary slightly depending on how quickly the vegetables are chopped and how long the lentils need to become tender.
Variations
Use Spicy Italian Sausage
Replace the sweet Italian sausage with hot Italian sausage for a noticeably spicier soup. You can also use a combination of sweet and hot sausage for balanced heat.
Try Turkey or Chicken Sausage
For a lighter variation, substitute Italian-style turkey or chicken sausage. Because leaner sausage may release less fat, you might need a little additional olive oil when sautéing the vegetables.
Add More Vegetables
This soup is easy to customize with vegetables you already have. Chopped zucchini, kale, diced tomatoes, green beans, or additional mushrooms can all work well.
Make It Extra Spicy
Increase the crushed red pepper or add a pinch more immediately before serving. This lets you increase the heat without changing the other flavors significantly.
Substitute Kale for Spinach
Chopped kale makes an excellent alternative to spinach. Add it a little earlier so the tougher leaves have enough time to become tender.
Add Parmesan
A sprinkle of grated Parmesan over each serving adds a salty, savory finish. A Parmesan rind can also be simmered in the broth and removed before serving for additional flavor.
Make It More Brothy
Lentils continue absorbing liquid as the soup sits. If you prefer a thinner consistency, add additional chicken broth until it reaches your desired texture.
Storage/Reheating
Allow leftover Sausage and Lentil Soup to cool before transferring it to airtight containers. Store it in the refrigerator for up to 3–4 days.
The lentils may absorb some of the broth during storage, making the soup noticeably thicker the next day. Stir in a splash of chicken broth or water when reheating if you want to restore its original consistency.
For stovetop reheating, place the desired amount in a saucepan and warm over medium-low heat, stirring occasionally, until heated through. Individual portions can also be reheated in the microwave, stirring partway through to encourage even heating.
For longer storage, freeze cooled soup in freezer-safe containers, leaving some room for expansion. Freeze for up to 3 months for the best quality. Thaw overnight in the refrigerator before reheating. If possible, fresh spinach and lemon juice can be added after reheating for an especially fresh finish.
FAQs
1. What kind of lentils are best for Sausage and Lentil Soup?
Brown or green lentils are excellent choices because they become tender while generally maintaining their shape. Red lentils cook much faster and tend to break down, producing a thicker, softer soup.
2. Do I need to cook the lentils before adding them?
No. The dry lentils cook directly in the chicken broth, where they absorb the savory flavors of the sausage, vegetables, and seasonings.
3. Do lentils need to be soaked before making this soup?
Most brown and green lentils don’t require soaking. Simply sort through them for any debris and rinse them thoroughly under cool water before adding them to the soup.
4. Can I make Sausage and Lentil Soup ahead of time?
Yes. This soup is well suited to making ahead because its flavors continue to develop during storage. Keep it refrigerated in an airtight container and reheat only the amount you plan to serve.
5. Why did my lentil soup become so thick?
Lentils naturally absorb liquid during cooking and continue absorbing broth as the soup cools. Simply add extra chicken broth or water when reheating until you reach your preferred consistency.
6. Can I use canned lentils instead?
Yes, but canned lentils are already cooked and shouldn’t simmer for the full 25 minutes. Drain and rinse them, then add them toward the end of cooking and simmer only long enough to heat them through.
7. Can I substitute something for the leeks?
Yes. Yellow or white onion makes a convenient substitute. The flavor will be slightly different, but onions still provide an excellent aromatic base for the soup.
8. How can I tell when the lentils are done?
The lentils should be tender all the way through without being hard or crunchy in the center. Ideally, brown or green lentils will remain mostly intact rather than completely falling apart.
9. Why is lemon juice added at the end?
Fresh lemon juice provides acidity that balances the rich sausage, earthy lentils, and savory broth. Adding it at the end preserves its bright, fresh flavor.
10. Can Sausage and Lentil Soup be frozen?
Yes. Let the soup cool completely before portioning it into freezer-safe containers. Freeze for up to 3 months for the best quality, then thaw in the refrigerator and reheat gently on the stovetop or in the microwave.
Conclusion
