How was your weekend? Did you get up to anything fun? Say hi in the comments and share something you enjoyed! I’m about to eat this red lentil curry by Pinch of Yum!
My weekend was terribly uneventful. I’m still trying to get over the flu, so I’ve been resting a lot more than usual, going on walks, and generally overthinking my life (but what else is new on that front, ha ha?). I haven’t been super interested in cooking or creatively inspired, but don’t fear: I have lots of recipes left to share before I shift to creating spring recipes. Recipes like this soup, for instance!
I created this southwestern lentil, kale, and butternut squash soup a few months ago when the craving for something warm, smoky, and satisfying struck. Soup paired with bread and cheese or avocado is often my answer when we need a stick-to-your-ribs meal fast, and this creation of mine was a big hit with the fam jam!
This soup has a southwestern flavour profile, but the lentils are a nice departure from the black beans you would normally find in a southwestern soup. There are also crimini mushrooms in here, which provide a bit of depth and meatiness. And the spices! I think you’ll fall in love with the flavour profile of this soup thanks to the cumin, smoked paprika, chili powder, coriander, and cayenne.

to make this soup, you’ll:
- Saute onions and garlic in some oil. Add quartered mushrooms, salt, pepper, smoked paprika, cumin, coriander, chili powder, cayenne, butternut squash, lentils, and tomato paste.
- Add the vegetable broth and bring to a low boil. Simmer over medium heat until squash is tender, about 25 minutes. Add chopped kale and cook just until wilted. Add the lime juice and serve soup topped with fresh cilantro.

As I mentioned earlier, this soup pairs very well with avocado toast or simple bread and cheese.

I hope you love it! If you make it, let me know how you liked it by leaving a comment and rating below, and share a photo to Instagram and tag @upbeet.kitchen and #upbeetkitchen!

Served this soup with grilled cheese sandwiches for supper. Really tasty, and perfect spice combo. I like that it wasn’t too tomato-ey also, since it’s easier on my stomach. Great recipe.
