Make It Your Way

I love how flexible this Lentil Sausage Soup Recipe is—you can easily tailor it to your taste or pantry. I sometimes swap out the sausage for ground turkey when I want something lighter or toss in a handful of spinach right at the end for a boost of greens.

Variation: Once, I added chopped kale during the last 5 minutes, which gave the soup a wonderful earthiness and a nice pop of color — highly recommend trying it!
For lower sodium: Using low-sodium broth helps you control the saltiness since sausage already has plenty.
Milder version: Swap hot sausage for mild if you prefer less spice, or adjust hot sauce to your liking.
Slow cooker method: Perfect for busy days when you want to set it and forget it. I’ll walk you through that below.

Step-by-Step: How I Make Lentil Sausage Soup Recipe

A bowl of thick soup filled with small chunks of light brown lentils, beige-colored meat pieces, and diced red tomatoes, all mixed in a warm, orange-brown broth with visible green herb bits scattered throughout. The soup has a slightly creamy texture with some small soft bits of onion and other vegetables. A silver spoon rests inside the bowl, which is white with tiny black speckles, placed on a white marbled surface with a soft off-white cloth beside it. photo taken with an iphone --ar 2:3 --v 7

Step 1: Cook the Sausage with Care

Start by removing the casings if you bought sausage links — that’s key to getting a nice crumbly texture for your soup. I like to preheat my pot over medium heat before adding the sausage. Cook it halfway uncovered so it browns well, then cover partially and stir occasionally to cook through evenly without drying out. It usually takes about 10-12 minutes. Set the cooked sausage aside on a paper towel-lined plate to drain off extra fat, but don’t toss the drippings — you’ll use a tablespoon of that to kick off the soup base.

Step 2: Sauté the Veggies for Flavor

Add the reserved drippings back to the pot along with a little butter, then toss in your diced onions, celery, and carrots. Cook them for about 4 minutes until they start softening and getting fragrant. Garlic goes in last, cooking about a minute so it doesn't burn but releases its aroma.

Step 3: Build the Soup Base

Sprinkle in the flour and tomato paste and cook, stirring for 2 minutes to get rid of that raw flour taste and deepen the tomato flavor. Then, slowly add the chicken and beef broths in splashes, scraping the bottom to lift those tasty browned bits — this is soup magic! Next, stir in Worcestershire sauce, hot sauce, lentils, bay leaf, and your dried herbs and spices. Bring everything to a boil, then lower the heat to a gentle simmer, covering the pot partially. Let it cook for about 45 minutes, stirring occasionally so the lentils don't stick.

Step 4: Finish with Sausage and Tomatoes

Toss the cooked sausage and drained diced tomatoes back into the pot, simmering for another 10 minutes. If you want a thinner broth, a splash of water or extra broth works wonders here. Taste and adjust your seasoning — sometimes a little extra salt or pepper can make all the difference before serving.

Top Tip

From my experience, letting the soup simmer gently and patiently is the key to success. Rushing this soup often results in lentils that are either mushy or undercooked and a broth that hasn’t fully developed its rich flavor.

Don't skip rinsing lentils: Brown lentils sometimes have a powdery coating that can muddy your soup’s flavor — a quick rinse fixes this.
Low heat simmer: Maintaining a low, steady simmer lets flavors meld and the lentils cook evenly without breaking apart too much.
Reserve sausage drippings: Using the fat from cooking the sausage to sauté the vegetables adds unmatched depth — it’s an easy way to boost flavor without extra ingredients.
Don’t stir too often: While occasional stirring is good, over-stirring lentil soup can break down the lentils, making your soup overly thick or mushy.

Lentil Sausage Soup - Serving Suggestion

Garnishes

I like to finish my bowls with a sprinkle of fresh parsley or a small handful of grated Parmesan. It adds just the right fresh brightness and a touch of savory saltiness that complements the hearty soup beautifully.

Crusty bread or a simple green salad pairs perfectly here. When I want a little extra comfort, I grab a rustic baguette to soak up the broth — trust me, it’s a total game-changer.

For a dinner party, try serving this Lentil Sausage Soup Recipe in mini bread bowls — it looks stunning and feels extra cozy. I’ve also ladled it over cooked farro or rice for a heartier meal that doubles as a stew.

Make Ahead and Storage

Storing Leftovers

I store leftover soup in airtight containers in the fridge, and it usually lasts about 3-4 days. Lentil soups tend to thicken as they chill, so I just add a splash of broth or water before reheating.

Freezing

This recipe freezes beautifully! Portion into freezer-safe containers, leaving some space at the top. When I thaw it out, I like to heat it gently on the stove, which helps retain the soup’s texture and flavor.

Reheating

I usually reheat the soup gently on the stovetop, stirring occasionally and adding a splash of broth or water to loosen it up. The slow warming helps keep the lentils tender and the flavors fresh.

Frequently Asked Questions:

Can I use canned lentils for this soup?

Canned lentils aren’t ideal for this recipe because they tend to become mushy and don’t hold their shape well during cooking. Dry brown lentils work best as they cook evenly and keep a nice texture.

Can I make this soup in a slow cooker?

Yes! You can brown the sausage separately and then add all ingredients to a slow cooker. Cook on low for 7-8 hours or high for 4-5 hours. It’s an easy way to let flavors meld without watching the pot.

What if I want a vegetarian version?

You could swap the sausage for plant-based sausage or omit it entirely. Use vegetable broth instead of chicken and beef broth and consider adding extra veggies or smoked paprika for a smoky depth.

How spicy is this soup?

While it includes hot sausage and a bit of hot sauce, the heat is very mild and balanced by the richness of the broth and lentils. If you prefer less spice, use mild sausage and skip the hot sauce, or add it gradually to taste.
