Wild Mushroom, Caramelized Onion, and Kale Soup Recipe
Introduction
This Wild Mushroom, Caramelized Onion and Kale Soup is a comforting and flavorful dish perfect for chilly days. Combining earthy mushrooms, sweet caramelized onions, and nutritious kale, it’s a hearty soup that’s both nourishing and delicious.

Ingredients
- 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
- 1/2 cup coconut milk or coconut cream
Instructions
- Step 1: 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.
- Step 2: 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.
- Step 3: Add the whole shiitake mushrooms and the sliced baby bella or cremini mushrooms to the pot with the sautéed onions, garlic, and seasoning. Cook for about 5-7 minutes, stirring occasionally, until the mushrooms are softened and begin to turn golden.
- Step 4: Pour in the chicken or vegetable broth, stirring to combine with the sautéed mushroom mixture. Bring everything to a boil, then add the loosely chopped kale leaves. Reduce the heat to low, cover the pot, and let it simmer for 20 minutes so the flavors meld and the kale becomes tender.
- Step 5: Uncover the pot and stir in the coconut milk or coconut cream. Let the soup heat through for a minute or two. Taste and season with additional salt and pepper if needed before serving.
Tips & Variations
- For a richer flavor, use coconut cream instead of coconut milk when finishing the soup.
- Try adding a splash of white wine when cooking the mushrooms for added depth.
- Substitute kale with spinach or Swiss chard if preferred for a different leafy green texture.
- Serve with crusty bread or a sprinkle of fresh herbs like thyme or parsley for added freshness.
Storage
Store any leftover soup in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove over low heat, stirring occasionally. If the soup thickens too much when cooled, add a splash of broth or water to reach desired consistency before warming.

FAQs
Can I make this soup vegan?
