Ingredients & Instructions
Ingredients
- 2 tbsp extra-virgin olive oil
- 1 large sweet onion, sliced ½ inch thick
- 4 cloves garlic, finely chopped
- 1 tsp sea salt or pink salt
- ½ 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
- 2 cups loosely chopped kale leaves
- ½ cup coconut milk or coconut cream
Step-by-Step Instructions
1. Caramelize the Onions
Heat the olive oil in a large pot over medium heat. Add the thick-sliced onions and cook slowly, stirring occasionally, for 10–15 minutes. They should turn golden and soft—this step builds the foundation of the soup’s rich, sweet flavor. Don’t rush it; low and slow is key.
2. Add Garlic & Seasoning
Stir in the finely chopped garlic along with the salt and black pepper. Cook for 1–2 minutes, just until fragrant. Avoid browning the garlic so it doesn’t turn bitter.
3. Cook the Mushrooms
Add both the shiitake mushrooms and sliced baby bellas. Let them soften and release their moisture, cooking for 5–7 minutes. They should develop a slight golden color and deepen in flavor.
4. Add Broth & Kale
Pour in the broth and stir everything together. Bring the pot to a gentle boil, then add the chopped kale. Reduce heat to low, cover the pot, and simmer for 20 minutes so the kale softens and the flavors meld together.
5. Finish with Coconut Milk
Remove the lid and stir in the coconut milk or coconut cream. This creates a silky finish and balances the earthy mushrooms with subtle richness. Warm the soup for another minute or two—not boiling—to preserve the creamy texture. Taste and adjust seasoning if needed.
Serve warm and enjoy the comforting aroma and deep, savory flavors.
Cooking Tips & Variations
1. Intensify Flavor
- Use a mix of wild mushrooms (oyster, chanterelle, maitake) for an elevated depth.
- Add a splash of white wine after caramelizing onions for acidity and dimension.
2. Make It Creamier or Lighter

- For a lighter version, use light coconut milk or reduce the amount.
3. Add Protein for a Complete Meal

- Shredded chicken works well if you’re using chicken broth.
4. Enhance with Herbs & Spices

- Leave everything chunky for a rustic finish.
