Ingredients & Instructions
Ingredients
- 2 tbsp extra-virgin olive oil
- 1 large sweet onion, sliced ½ inch thick
- 4 garlic cloves, 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 chicken or vegetable broth
- 2 cups loosely chopped kale leaves
- ½ cup coconut milk or coconut cream
Step-by-Step Instructions (with practical tips)
1. Caramelize the Onions
Heat olive oil in a large pot over medium heat. Add the sliced onions and sauté gently for 10–15 minutes, stirring occasionally.
Tip: Give them time to brown slowly—this builds the soup’s sweetness and depth.
2. Add Garlic and Seasoning
Stir in garlic, salt, and pepper. Cook 1–2 minutes until the garlic smells aromatic.
Tip: Lower heat slightly if needed to prevent burning.
3. Sauté the Mushrooms
Add both shiitake and cremini mushrooms. Cook 5–7 minutes, stirring occasionally, until they soften and begin to brown.
Tip: Let them sit undisturbed for a minute between stirs for optimal browning.
4. Simmer with Broth and Kale
Pour in the broth and mix well. Bring to a boil, then add kale leaves. Reduce heat to low, cover, and simmer for 20 minutes.
Tip: Cooking the kale low and slow keeps it tender instead of chewy.
5. Finish with Coconut Milk
Uncover the pot, stir in the coconut milk, and let the soup warm through for 1–2 minutes.
Taste and adjust seasoning before serving.
