Sausage Lentil Soup with Kale

Why You’ll Love Sausage Lentil Soup

Before we get into the details, this is one of those recipes that proves why soup deserves a regular spot at the dinner table. With protein, fiber-rich lentils, vegetables, and greens all simmered together in one pot, it really is a full meal in a bowl. If you already love cozy lentil soups like my lentil and brown rice soup or red lentil tortilla soup—or heartier options like my lasagne soup—this one fits right into that dinner rotation.

Lentils are one of the most approachable legumes around. They’re easy to digest, naturally high in fiber and protein, and cook beautifully without soaking (or you can use fully cooked lentils to make this especially weeknight-friendly). Paired with sausage, vegetables, and greens, this soup checks every box and is especially good served with something simple like quinoa cornbread, crusty bread, or a green salad.

Ingredients You’ll Need

• Olive oil: The base for building flavor and browning the sausage.
• Italian sausage or chorizo: Pork sausage adds richness, poultry sausage keeps things lighter, and vegan sausage works well if you’re eating plant-based. Sweet sausage keeps the soup mellow, while spicy sausage adds more heat and depth.
• Onion, carrots, and celery: A classic aromatic trio that creates balance and body.
• Garlic: Brings warmth and savory backbone to the soup.
• Sea salt and black pepper: Essential for seasoning as you go.
• Dried Italian seasoning: Adds gentle herb flavor without overpowering the soup.
• Crushed red pepper flakes or Calabrian chiles (optional): For a little heat if you like it.
• Brown lentils or cooked lentils: Brown or green lentils work best here since they hold their shape; red lentils will cook too quickly and become soft.
• Bay leaves: Add subtle background flavor as the soup simmers.
• Crushed or diced tomatoes: I prefer jarred tomatoes here for a cleaner, brighter tomato flavor.
• Water or stock: Vegetable, chicken, or turkey stock all work. A splash of red wine adds depth if you have it.
• Kale or cabbage: Adds color, texture, and freshness at the end.
• Parmesan or infused olive oils: Optional but delicious for serving!

How to Make This Sausage Lentil Soup

Step 1: Heat the olive oil in a large pot over medium heat. Add the sausage and break it up with a wooden spoon or potato masher. Let it brown well, about 5 minutes — this step builds a lot of the soup’s flavor. Add the onion, carrots, celery, garlic, a pinch of salt, Italian seasoning, and red pepper flakes if using. Cook with the sausage until the vegetables begin to soften, about 5 minutes.

Step 2: Stir in the lentils, bay leaves, tomatoes, water or stock, and black pepper. Bring to a simmer and cook until the lentils are tender but still hold their shape, about 40 minutes. If you’re using cooked lentils, reduce the liquid slightly and simmer just until the vegetables are tender and the flavors have melded.

Step 3: Add the kale or cabbage and cook for 3-5 minutes, just until tender. Remove the bay leaves, taste, and adjust seasoning as needed. Serve hot with grated Parmesan, chili-infused olive oil, or garlic-infused olive oil if you like.

If you make this, I’d love to hear how you adapt it. This is one of those soups that really welcomes personal tweaks and different ways of eating.
