Red Lentil Tomato & Sausage Soup

If you ask me, soup season is pretty much here, but you’d never know based on the looks outside as I write this blog! It’s sunny and as warm as it could be for a mid-September day, and as much as I live for weather like this, I know that fall is creeping in. The dip in temperatures at night is undeniably colder than it was just a few weeks ago. In about a week, it will be the fall solstice, and honestly, I’m not mad about it. Our bodies start moving differently as the cold comes in, our cravings change, and I love that feeling. 

I love a good soup, and I promise to deliver on creating more delicious one pot meals to make life a little easier as we head into colder days. Soups are a wonderfully delicious and relatively inexpensive meal to make. I love that you can clear out your fridge and freezer and have a nutrient dense, protein rich meal (or meals if you live alone) on the table in approximately 30-45 minutes. As most of us know, the longer a soup sits, the tastier it gets, so double batch, triple batch, throw some in the freezer, and definitely have a bowl the next day!

What Does Tomato Lentil Soup Taste Like?

Lentil tomato soup is earthy, subtly sweet, and deeply savoury, especially when paired with sausage and warming spices. The lentils break down slightly, giving the soup a creamy, rich consistency without needing cream. The combination of crushed tomatoes, fresh heirlooms, and a touch of tomato paste gives it a sweet, tangy backbone that ties everything together. And let’s not forget the sausage, it adds a peppery, spiced depth that transforms this into the best tomato and lentil soup recipe you’ll try all season!

Red Lentil Tomato & Sausage Soup Ingredients

This recipe makes use of fridge staples, pantry heroes, and a few fresh favourites:

  • Olive oil: Provides a rich base for sautéing the aromatics and adds a smooth, silky texture to the soup.
  • Chilli flakes: Add subtle heat and depth to the overall flavour without overpowering the dish.
  • Onion: Brings sweet, savoury flavour and forms part of the essential soup base.
  • Carrots: Add natural sweetness and contribute to the hearty texture of the broth.
  • Celery: Balances the sweetness of the carrots and onion while adding aromatic depth.
  • Garlic: Offers a warm, pungent aroma that deepens the savoury base of the soup.
  • Sausage: Use your sausage of choice, Italian, vegan, whatever you desire! Each sausage will deliver a rich, meaty flavour with a touch of spice that enhances the body of the soup.
  • Tomato paste: Concentrates tomato flavour and adds a slight tang that sharpens the broth.
  • Heirloom tomatoes: Provide freshness and acidity, helping to build a well-rounded tomato profile. These babies are all over the farmers’ markets right now. Get them fresh!
  • Crushed tomatoes: Create the bulk of the soup’s tomato base, adding body and richness.
  • Dried thyme: Offers earthy, slightly minty notes that balance the acidity of the tomatoes.
  • Dried oregano: Brings a familiar Mediterranean flavour that complements both the tomato and sausage.
  • Red lentils: Cook quickly and melt into the broth, providing protein, fibre, and a creamy texture without the need for dairy.
  • Vegetable or chicken stock: Forms the flavorful liquid backbone of the soup and carries all the ingredients together.
  • Parmigiano rind (optional): Infuses the soup with a salty, nutty complexity as it simmers.
  • Kale: Adds a vibrant pop of green and an earthy bite, plus a boost of nutrients just before serving.

How to Make Red Lentil Tomato Soup

Making this soup is quick and easy. Packed with pantry staples, this soup comes together in under an hour and serves 6. Let’s get into it!

Sauté the Aromatics

Start by heating a generous drizzle of olive oil in your large Dutch oven over medium heat. Add the onion, carrots, celery, and a pinch of chilli flakes. Stir frequently, cover the pot with a lid, and let the vegetables soften and sweat. This step helps develop the base flavour of your soup.

Build the Flavour

Once the veggies are tender, stir in the garlic until fragrant. Add the sausage to the pot, breaking it apart with a spatula as it browns. Stir in the tomato paste and toast it for about a minute, then mix in the chopped fresh tomatoes and the can of crushed tomatoes.

Simmer the Soup

Add in the dried thyme, oregano, and rinsed red lentils. Pour in the stock (or water), toss in the Parmigiano rind, and season everything with salt and pepper. Cover and simmer the soup for 15 to 20 minutes until the lentils are soft and the flavours are well developed.

Finish with Greens and Serve

Once the lentils are tender, stir in the chopped kale and let it wilt down into the soup. Taste and adjust the seasoning if needed. Ladle the soup into bowls and top with freshly shaved Parmigiano or Pecorino for a cozy, hearty finish.

How to Customize This Homemade Tomato Soup

This easy sausage soup recipe is incredibly flexible and can be adjusted to suit your pantry or dietary needs. It’s super vegan friendly, all you need to do is skip the parmigiano rind and use your choice of sausage. Try adding chickpeas or a veggie ground to beef up the soup. Craving more heat? Add a spoonful of harissa or an extra pinch of chilli flakes to turn up the spice. And if you desire more texture and staying power, stir in cooked grains like quinoa or farro near the end of cooking. This soup is truly adaptable to what you have on hand and your personal preferences!

Want to Make This Tomato Soup Creamy?

This soup is already creamy thanks to the lentils, but if you’re craving even more creaminess, try blending half the soup with an immersion blender and stirring it back in. You can also add a splash of coconut milk or cream at the end for a luxurious twist.

How to Store and Reheat This Homemade Lentil Tomato Soup

Leftovers are your best friend with this recipe.

  • Storage: Transfer cooled soup to an airtight container and refrigerate for up to 5 days.
  • Freezing: It freezes beautifully—just leave out the Parmigiano rind if you’re freezing the whole batch.
  • Reheating: Warm gently on the stove over medium-low heat or microwave in 1–2 minute intervals, stirring in between.
