Step‑by‑Step Instructions for Wild Mushroom, Caramelized Onion, and Kale Soup
Step 1: Heat the Oil
Begin by heating 2 tablespoons of extra-virgin olive oil in a large pot over medium heat. Allow the oil to warm for about a minute until it shimmers slightly, signaling readiness for cooking. This will set the stage for a rich flavor base that brings out the best in the Wild Mushroom, Caramelized Onion, and Kale Soup.
Step 2: Caramelize the Onions
Add 1 sliced sweet onion to the pot and sauté it gently for 10 to 15 minutes, stirring occasionally. Watch as the onions turn golden brown and become sweetly aromatic; the caramelization process will enrich the soup’s depth of flavor. Be patient, as this step is key to achieving that lovely sweetness.
Step 3: Add Garlic and Spices
Once the onions are beautifully caramelized, stir in 3 minced garlic cloves along with a pinch of sea salt and freshly cracked black pepper. Cook for another 1 to 2 minutes, stirring often, until the garlic becomes fragrant and lightly golden. This step enhances the aromatic profile of your Wild Mushroom, Caramelized Onion, and Kale Soup.
Step 4: Incorporate the Mushrooms
Next, add 8 ounces of whole shiitake mushrooms and 8 ounces of baby bella or cremini mushrooms to the pot. Cook these for 5 to 7 minutes, stirring frequently, until they soften and start turning golden brown. This step allows the mushrooms to release their moisture and intensify their flavors, making the soup even heartier.
Step 5: Pour in the Broth
Carefully pour in 4 cups of organic chicken or vegetable broth, bringing it to a gentle boil over medium-high heat. Stir well to combine all the ingredients, allowing the soup’s wonderful aromas to fill your kitchen. This rich broth forms the delicious base for your Wild Mushroom, Caramelized Onion, and Kale Soup, setting the stage for the next ingredients.
Step 6: Add the Kale
Once boiling, toss in 2 cups of chopped kale leaves, ensuring they are submerged in the broth. Reduce the heat to low, cover the pot, and let it simmer for about 20 minutes. This allows the flavors to meld beautifully while keeping the kale vibrant and retaining its tender texture for the perfect soup outcome.
Step 7: Stir in Coconut Milk
After the simmering time, stir in 1 cup of coconut milk or coconut cream, allowing the mixture to heat gently for 3 to 5 minutes. This step adds a luscious creaminess to your Wild Mushroom, Caramelized Onion, and Kale Soup, balancing the earthy flavors with a touch of richness. Taste and adjust seasoning as needed for an extra burst of flavor.

Expert Tips for Wild Mushroom, Caramelized Onion, and Kale Soup

Caramelization Time: Be patient with onions; they need 20-30 minutes over low heat to deepen in flavor and sweetness. Rushing this step leads to a less flavorful soup.
