Sausage and Lentil Soup
This tasty Sausage and Lentil Soup has roasted red pepper, and I love how spicy Italian Sausage adds flavor to this soup! And this recipe doesn’t use many lentils so it’s lower in carbs than you might think!
Right now the entire east coast of the U.S. is snowed in, so it seems like soup is a good menu choice for lots of people. And even though there’s not snow at my house I’m glad I just updated the photos and I have some of this Sausage and Lentil Soup in the freezer!
I did change the recipe slightly for this update, using a whole package (19.5 oz.) of turkey Italian sausage which makes this a more carb-conscious recipe. Lentils are high in fiber too, so I think this soup would be a good choice for some low-carb eaters with that change, although it’s probably not suitable for people who are strictly limiting carbs. And more sausage, mmm. I love all the flavors in this soup, hope you enjoy.
What ingredients do you need for this recipe?
- turkey or pork Italian Sausage
- olive oil
- brown lentils
- chicken broth or homemade chicken
- ground fennel (affiliate link), do not leave out
- Dried Thyme (affiliate link)
- Dried Sage (affiliate link)
- Roasted Red Peppers in a jar (affiliate link)
What kind of red pepper can you use?
I use roasted red pepper from a jar, which made this soup quick and easy to get on the table! You can also use diced fresh red bell peppers, and add them a bit earlier in the cooking time.
Can you use red lentils for this soup?
I love red lentils in soup and if you wanted to use them in this recipe they would cook a bit more quickly than the brown ones.
