Description

This Wild Mushroom Caramelized Onion and Kale Soup is rich, cozy, and full of deep savory flavor. Sweet caramelized onions, earthy mushrooms, and tender kale simmer together in a creamy coconut broth for a comforting, nourishing soup that’s perfect for busy weeknights or slow weekends.


Ingredients

Scale

For the soup base:

  • 2 tablespoons extra-virgin olive oil

  • 1 large sweet onion, sliced ½-inch thick

  • 4 cloves garlic, finely chopped

  • 1 teaspoon sea salt or pink salt

  • ½ teaspoon freshly cracked black pepper

  • 2 cups whole shiitake mushrooms

  • 2 cups baby bella or cremini mushrooms, sliced

  • 4 cups organic chicken broth or vegetable broth (gluten-free)

  • 2 cups loosely chopped kale leaves

For finishing:

  • ½ cup coconut milk or coconut cream


Instructions

  1. Heat the olive oil in a large pot over medium heat. Add the sliced onion and sauté, stirring occasionally, until deeply golden and caramelized, about 10–15 minutes.

  2. Stir in the garlic, salt, and black pepper. Cook for 1–2 minutes until fragrant, being careful not to burn the garlic.

  3. Add the shiitake and cremini mushrooms. Cook for 5–7 minutes, stirring occasionally, until softened and lightly golden.

  4. Pour in the broth and stir well. Bring to a gentle boil, then add the chopped kale.

  5. Reduce heat to low, cover, and simmer for 20 minutes until the kale is tender and flavors are well combined.

  6. Stir in the coconut milk or coconut cream. Heat through for 1–2 minutes, taste, and adjust seasoning if needed. Serve warm.

Notes

Coconut cream creates a richer, creamier soup, while coconut milk keeps it lighter.

Let the onions caramelize fully—this is where the depth of flavor really shines.

For a thicker texture, blend 1–2 cups of the soup and stir it back in.

Leftovers taste even better the next day as the flavors continue to develop.
