Ingredients

Scale

For the 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

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, until the onions are golden brown and caramelized, about 10-15 minutes. This step brings out the natural sweetness of the onions.
Sauté garlic and season: Stir in the finely chopped garlic, sea salt or pink salt, and freshly cracked black pepper. Continue to cook for 1-2 minutes until the garlic becomes fragrant, being careful not to let it burn.
Cook mushrooms: Add the whole shiitake mushrooms and sliced baby bella or cremini mushrooms to the pot with the onions, garlic, and seasoning. Cook for 5-7 minutes, stirring occasionally, until the mushrooms soften and develop a slight golden color for extra flavor.
Add broth and kale, simmer: Pour in the chicken or vegetable broth, stirring to combine with the mushroom mixture. Bring to a boil, add the chopped kale leaves, then reduce heat to low. Cover and let simmer gently for 20 minutes, allowing flavors to meld and kale to soften.
Finish with coconut milk: Uncover the pot and stir in the coconut milk or coconut cream. Heat through for another 1-2 minutes. Taste and adjust seasoning with additional salt and pepper if needed before serving.

Notes

For a vegan version, use vegetable broth and coconut cream.
You can swap kale with other hearty greens like spinach or Swiss chard if preferred.
Using coconut cream instead of milk enriches the soup and adds a silkier texture.
The caramelization of onions is key to developing a deep, sweet flavor base.
Sea salt or pink salt is recommended for a cleaner, less processed salt taste.
The soup is gluten-free if you use gluten-free broth and ingredients.
