Red Lentil Vegetable Stew with Sourdough

lentil soup with sourdough

If you are looking for a hearty and healthy stew to eat with your sourdough bread, then this red lentil vegetable stew might be for you! It is perfect for a weeknight meal because it takes less than an hour from start to finish because red lentils cook relatively fast compared to most other types of lentils. This recipe can easily be modified to include other vegetables and spices as well. Squash and sweet potatoes are great additions to this recipe, although they will need to cook a bit longer. I recommend topping this stew with toasted sourdough or sourdough crackers. For sourdough recipes, check out my other posts, such as my Basic Sourdough recipe or Sourdough with Flax and Chia.

This recipe is adapted and inspired by Smitten Kitchen’s Stewed Lentils and Tomatoes. I first tried Smitten Kitchen’s recipe during grad school (until then, I had actually never tried lentils before!) Over the years, I’ve modified the recipe to use red lentils (instead of French green lentils) and different seasonings, as well as added kale. I like to add red pepper flakes when I make this recipe because we enjoy spicy food. However, I suggest omitting them if you are sensitive to spicy foods. I enjoy making this recipe on a Sunday and eating it for easy lunches and dinners during the week. It also freezes well.

Some notes:

The vegetable broth can be substituted with water, although you will likely need to add more salt. I would suggest adding the spices cautiously, then adjusting to your preference. I used canned whole peeled tomatoes, but canned diced tomatoes would work too. Also, this recipe is vegan if you omit the Parmesan cheese.
