Step‑by‑Step Instructions for Wild Mushroom, Caramelized Onion and Kale Soup
Step 1: Sauté the Onions
In a large pot, heat 2 tablespoons of olive oil over medium heat. Once the oil shimmers, add 1 large sliced onion, stirring occasionally. Cook for about 10-15 minutes until the onions turn a rich golden brown, releasing their sweetness. This caramelization will create a flavor foundation for your Wild Mushroom, Caramelized Onion, and Kale Soup.
Step 2: Add Garlic and Mushrooms
Stir in 3 minced garlic cloves, along with a pinch of salt and pepper to taste. Next, add 8 ounces of sliced wild mushrooms, stirring to combine. Continue cooking for another 5-7 minutes until the mushrooms soften and turn golden. This enhancement of flavors will elevate your soup’s profile, ensuring every spoonful bursts with umami.
Step 3: Pour in the Broth
Now it’s time to pour in 6 cups of vegetable broth, raising the heat to high. Bring the mixture to a gentle boil, watching the bubbles break the surface. This step will meld all the flavors together, creating a savory base for your soup. Once it reaches a boil, reduce the heat to low and prepare for the final touches.
Step 4: Add the Kale
Add 4 cups of chopped kale to the pot, stirring gently. Cover the pot and let it simmer on low heat for 20 minutes. During this time, the kale will wilt beautifully, infusing the soup with vibrant nutrients and a slight bitterness that perfectly balances the sweetness of the caramelized onions.
Step 5: Finish with Coconut Milk
Finally, stir in 1 cup of creamy coconut milk for a luscious finish. Let the soup simmer uncovered for an additional 5 minutes, allowing the flavors to meld. Taste and adjust the seasoning with salt and pepper if needed. Your Wild Mushroom, Caramelized Onion, and Kale Soup is now ready to be served, comforting and delicious!
