In a spacious pot, heat the olive oil over medium heat, allowing it to warm up for about 1-2 minutes.
Add the finely diced onion to the pot and sauté for 3-4 minutes, stirring occasionally, until it turns soft and translucent.
Introduce the minced garlic, diced carrots, and celery to the mix. Continue to sauté for an additional 5 minutes, allowing the vegetables to soften and become aromatic.
Add the cubed butternut squash to the pot, cooking for about another 3 minutes, until it begins to soften.
Pour in the vegetable broth and add the rinsed wild rice along with the dried thyme, sage, bay leaf, and season with salt and pepper to your preference.
Increase the heat until the mixture reaches a gentle boil. Once boiling, reduce the heat to low, cover the pot, and allow it to simmer for approximately 45 minutes or until the wild rice is tender and has expanded.
About 10 minutes before the soup is finished, incorporate the chopped kale and stir in the fresh lemon juice for brightness and acidity.
Before serving, remove the bay leaf and adjust the seasoning with additional salt and pepper if desired. Serve hot in bowls.
Notes
Ladle the vibrant soup into bowls and sprinkle with freshly chopped parsley for a lovely burst of color. Accompany the soup with warm, crusty bread for a perfect autumn meal.
