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 Onions: Heat the extra-virgin olive oil in a large pot over medium heat. Add the sliced sweet onion and sauté, stirring occasionally, until the onions are golden brown and caramelized, about 10-15 minutes. This step enhances the natural sweetness of the onions and builds the soup’s foundational flavor.
  2. Sauté Garlic and Seasonings: Stir in the finely chopped garlic, sea salt or pink salt, and freshly cracked black pepper. Cook for 1-2 minutes until the garlic is fragrant, taking care not to burn it, which adds depth to the soup.
  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 soften and develop a golden color, intensifying their umami flavor.
  4. Add Broth and Kale: Pour in the chicken or vegetable broth, stirring to combine with the mushroom mixture. Bring 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, then taste and adjust seasoning with additional salt and pepper if needed. The coconut adds a creamy richness that balances the savory soup beautifully.

Notes

  • For a vegan and vegetarian option, use vegetable broth.
  • You can substitute kale with spinach or Swiss chard if preferred.
  • Using coconut cream instead of milk will result in a richer, creamier soup.
  • Ensure to simmer gently to avoid breaking down the kale too much, preserving its texture.
  • For extra texture, garnish with toasted nuts or seeds before serving.
