Tomato Lentil Soup with Sausage is a thick, hearty, whole meal soup that's easy to make in the Instant Pot. It has four main ingredients and six spices. You don't need any soup stock or broth for this one. Brown the meat a little, dump everything else in, set it, and forget it!
I've been making this soup regularly since we moved into our motorhome full time. It's a wonderful, complete meal that seems like it's been simmering for hours - perfect for a weeknight dinner! Serve it with Gluten Free Garlic Bread Sticks or Seed Crackers, if you wish.
Tomato Lentil Soup is suitable for gluten free, dairy free, and nut free diets. It's a very budget-friendly dish, too! For more money-saving ideas, read The Affordable Gluten Free Diet.
- Sausage - I prefer to use Sweet Italian sausage, but if you like more heat try a hot one!
- Crushed Tomatoes - Crushed tomatoes don't have seeds in them, so they're nice for dishes like this one.
- Sweet Potatoes - If you don't have any sweet potatoes on hand, butternut squash works just as well here. I recommend the frozen cubes, so you don't have to cut up the squash. Carrots will also work.
- Paprika - I love the depth of flavour that smoked paprika adds to this dish.
See recipe card for quantities.
Set the Instant Pot to SAUTE and brown the sausages.
Cut the sausages into chunks, add the other ingredients, and set the Instant Pot to PRESSURE cook.
Allow a slow release for 15 minutes for the flavours to blend.
This recipe is designed to make an easy weeknight dinner. There are plenty of options for substitutions in case you don't have the exact ingredients on hand.
- Sausage - Instead of sweet Italian, you can use other types of sausage, or even ground beef. If you use bulk sausage or ground beef, you'll be able to eliminate the step of cutting up sausage links.
- Sweet Potatoes - Use cubes of butternut squash or carrot, if that's what you have available. I recommend frozen butternut squash, because it's so much easier than cutting up a fresh one.
I like the convenience of making tomato and lentil soup in my Instant Pot. If you don't have a pressure cooker, you could use a large pot on the stovetop. The procedure will not be much different, except that you'll need to stay with it and watch it closer.
Leftovers store nicely, covered, in the refrigerator for a few days, or in the freezer for a month or two.
Recipe Tips and FAQ's
Unlike beans, you don't have to soak lentils before cooking. Lentils are the easy legume to work with! Green lentils will cook in about 20 minutes. Red lentils cook even faster!
Lentil soup is the ideal way to consume these nutritious legumes. Next to soybeans, lentils have more protein than any other beans. They are also an inexpensive source of fibre, potassium, folate, and iron.
You can still make tomato soup with lentils if you don't have an Instant Pot. Using a large pot on the stovetop, follow the instructions in a similar way. The main difference will be that you need to stay with it to keep an eye on it more.
After you've added all of the ingredients to the pot, cover it and bring the liquid to a boil. Then, reduce the heat. Stirring occasionally, allow the soup to simmer until the lentils and sweet potatoes are soft, about 30 minutes or so.
