Ingredients

Scale

Soup Base

  • 2 tbsp extra-virgin olive oil
  • 1 large sweet onion, sliced 1/2 inch thick
  • 4 cloves garlic, finely chopped
  • 1 tsp sea salt or pink salt
  • 1/2 tsp 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

  • 1/2 cup coconut milk or coconut cream

Instructions

  1. Caramelize the Onions: Heat the extra-virgin olive oil in a large pot over medium heat. Add the sliced sweet onion and sauté, stirring occasionally, for about 10-15 minutes until they are golden brown and caramelized. This step intensifies the sweetness and depth of flavor in the soup.
  2. Sauté Garlic and Season: Stir in the finely chopped garlic, sea salt or pink salt, and freshly cracked black pepper. Cook for 1-2 minutes until the garlic becomes fragrant, making sure it does not burn to maintain a balanced flavor.
  3. Cook Mushrooms: Add the whole shiitake mushrooms and sliced baby bella or cremini mushrooms to the pot. Cook for 5-7 minutes, stirring occasionally, until the mushrooms have softened and some pieces turn golden to enhance the umami flavor.
  4. Add Broth and Kale: Pour in the chicken or vegetable broth and stir well to combine. Bring the mixture to a boil, then add the loosely chopped kale leaves. Reduce heat to low, cover the pot, and let it simmer for 20 minutes to meld flavors and tenderize the kale.
  5. Finish with Coconut Milk: Uncover the pot and stir in the coconut milk or coconut cream. Heat through for 1-2 minutes. Taste the soup and adjust seasoning with additional salt and pepper if necessary before serving.

Notes

  • You can substitute the chicken broth with vegetable broth to make the soup fully vegetarian or vegan.
  • Using coconut cream instead of coconut milk will create a richer texture.
  • For a more robust mushroom flavor, allow mushrooms to brown slightly instead of just softening.
  • This soup pairs well with crusty gluten-free bread for a complete meal.
