    What to Serve with Tomato and Lentil Soup

    Tomato lentil soup makes for an excellent vegetarian meal, but it also can easily be served as a side dish! 

    Serve it as an entree with a side of Garlic Bread or Garlic Twists, Roasted Asparagus, or a chunk of crusty bread. 

    Serve it as a side dish next to a grilled cheese sandwich, Savory Pork Chops, or Sunday Meatloaf.

    Variations and Substitutions

    • Make it creamy. This soup really doesn’t need anything else, but if you’re looking for something a little more creamy feel free to add a splash of heavy cream of half-and-half. Keep in mind that it won’t freeze as well once dairy is added.
    • Add more veggies. Feel free to cook other veggies along with the onion and garlic to boost the nutrition of your soup. Celery and carrots, spinach, or kale would all be delicious additions!
    • Spice it up. Give your tomato and lentil soup a kick of heat with a sprinkle of red pepper flakes or cayenne pepper.
    • Add a grain. Mix in cooked quinoa or rice to bulk the soup up even more. If you do this you may want to add a little bit of broth so the soup doesn’t get way too thick.

    Storage Instructions

    Leftover lentil soup will last in an airtight container in the fridge for up to 5 days. 

    To reheat, warm in the microwave or on low in a pan on the stove until heated through. Be sure to stir periodically so the soup heats evenly and fully! 

    Can I Freeze Lentil Soup?

    Yes! This soup freezes beautifully. Simply let it cool completely, then store it in an airtight container in the freezer for 3-4 months.

    When you’re ready to serve, thaw in the fridge or warm from frozen on low in a pot until heated all the way through.

    Do Canned Lentils Taste Good?

    Definitely. While dried lentils are great, the prep for this soup just wouldn’t be as quick. And canned lentils work perfectly in my opinion. 

    Quick and easy, and they taste good!

      hmmm I think this might be whats tomorrow nights dinner!! thanks!

    2. I love tomatoes and the information from David is very interesting.

    3. I love lentil soup, so I’ll have to look into this recipe. I’ve grown fonder of tomatoes over the years (raw), so this might be good. Funnily enough, I’ve grown less fond of pizza sauce over the years; my palate must be changing.

    4. If I add quinoa to this recipe can I pressure can the soup or leave out the quinoa?
