Next, stir in the minced garlic, sliced carrots, and chopped celery. Cook this mixture for another 5 minutes, allowing the vegetables to soften and the flavors to meld, becoming fragrant.
Incorporate the diced butternut squash and potato into the pot. Stir everything together to ensure the vegetables are well mixed.
Pour in the vegetable broth, then sprinkle in the dried thyme, ground cumin, along with a pinch of salt and freshly cracked black pepper. Increase the heat to bring the mixture to a gentle boil, then reduce the heat to a simmer.
Cover the pot and let the soup simmer for 20-25 minutes, or until the butternut squash and potato pieces are fork-tender.
Once the vegetables have softened, fold in the chopped kale, cooking for an additional 5 minutes until the kale is tender and has wilted.
Remove the pot from heat, then squeeze in the fresh lemon juice. Taste the soup, adjusting seasoning with more salt and pepper if needed.
For a creamy texture, use an immersion blender to puree the soup to your desired consistency. For a chunkier texture, you may leave it as is for added bite.
Notes
Serve in warmed bowls with fresh parsley and lemon juice for added brightness.
