How to make butternut squash lentil soup

This butternut squash lentil soup is filled with nutrient-rich foods like lentils, butternut squash, leeks, and chard. It’s also very, very tasty — it got rave reviews from friends and family alike. In fact, it just might rival our current favorite, Italian White Bean Soup. The only time consuming part of this soup recipe is the chopping. It requires quite a bit of vegetable chopping: garlic, carrot, leek, butternut squash, and kale. As a time saver, you could chop all the veggies in advance and refrigerate until making the soup: this could make it a 30 minute meal. Another option is to use frozen cubed butternut squash, which can shave off quite a bit of time.

How to cut butternut squash

The hardest part of making this butternut squash lentil soup is cutting the butternut squash! How to cut butternut squash? Here’s what Alex and I do: First, slice off top of the squash, then the entire straight neck of the squash. Peel it and peel the round base. Cut the base in half and remove the seeds from each half with a spoon. Slice the neck into strips and then cubes. Then do the same with the rounded bottom part of the squash: slice it into strips and then cubes.

How to cut leeks

Except…for how to cut leeks! Cutting leeks can also be a source of confusion. Here’s how we cut leeks: first, we chop off the dark green stems of the leeks and the bottom root, then slice them in half length-wise. Then we place each leek half cut-side down on the cutting board and chop it into thin slices, resulting in half-moon shapes. Here’s the important part: rinse the sliced leeks thoroughly in a colander to remove any dirt. Because leeks are roots, there’s typically a lot of dirt in the bulb portion!

Think local: see if you can find some of these ingredients at your local farmer’s market, depending on the season!  We picked these up at Indy Winter Farmer’s Market.

This hearty butternut squash lentil soup is a comforting and nutrient dense superfood soup, featuring lentils, kale, and leeks.


  • 3 cloves garlic
  • 3 carrots
  • 3 large leeks or 1 large yellow onion (or a combination; 1 leek and 1 yellow onion works well)
  • 1 medium butternut squash (4 to 5 cups diced; use frozen diced as a time saver)
  • 1 bunch Tuscan kale or Swiss chard
  • 2 tablespoons olive oil
  • 1 teaspoon kosher salt
  • 8 cups vegetable stock (we used 6 cups broth and 2 water)
  • 1 1/2 cups brown or green lentils
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • Fresh ground pepper
  • 1 tablespoon lemon juice (optional)


  1. Mince the garlic. Peel and chop the carrots into half moons.
  2. Chop the leeks: chop off the dark green stems and the bottom roots, then slice each in half length-wise. Place each leek half cut-side down on the cutting board, then chop it into thin slices (resulting in half-moon shapes). Rinse thoroughly in a colander to remove any dirt.
  3. Chop the butternut squash: cut the butternut squash in half and scoop out the seeds. Peel the halves with a vegetable peeler, then chop them into small pieces.
  4. Wash the kale or chard, destem it, and chop the leaves into bite-sized pieces. (You can also wait to do this while the soup simmers in Step 6.) 
  5. In a large pot over medium heat, heat the olive oil; add the leeks or onions and sauté until softened, about 4 to 5 minutes. Add carrots and garlic and sauté for 3 to 4 minutes until softened.
  6. Add the squash, vegetable broth, lentils, thyme, oregano, and kosher salt, and bring to a boil. Reduce heat and simmer for about 20 minutes until the lentils and butternut squash are soft (taste test a few). In the last few minutes, add the chopped chard and simmer until tender. Add additional salt and pepper to taste. If desired, stir in the lemon juice.
