Step‑by‑Step Instructions for Wild Mushroom, Caramelized Onion, and Kale Soup
Step 1: Sauté the Onions
Begin by heating 2 tablespoons of extra-virgin olive oil in a large pot over medium heat. Once the oil is shimmering, add 1 sliced sweet onion and sauté for about 10-15 minutes, stirring occasionally until the onions are golden brown and caramelized. This process enhances their sweetness, creating a flavorful base for your Wild Mushroom, Caramelized Onion, and Kale Soup.
Step 2: Add Garlic and Seasoning
Next, stir in 3 cloves of freshly chopped garlic along with 1 teaspoon of sea salt and ½ teaspoon of freshly cracked black pepper. Cook for about 1-2 minutes, allowing the garlic to become fragrant. This aromatic mixture will deepen the savory notes of the soup, setting the stage for the addition of mushrooms.
Step 3: Incorporate the Mushrooms
Introduce 8 ounces of whole shiitake mushrooms and 8 ounces of baby bella mushrooms to the pot. Sauté the mushrooms for about 5-7 minutes until they soften and develop a beautiful golden color. This step is crucial; it enhances the umami flavor that makes your Wild Mushroom, Caramelized Onion, and Kale Soup both hearty and delightful.
Step 4: Pour in the Broth
Pour in 4 cups of chicken or vegetable broth, stirring to combine all the ingredients. Increase the heat to bring the mixture to a boil. Once boiling, add 4 cups of chopped kale to the pot, stirring it in gently to mix. The broth will infuse the kale and mushrooms, enriching the flavors of your soup.
Step 5: Simmer and Meld Flavors
Reduce the heat to low, cover the pot with a lid, and let the soup simmer for about 20 minutes. This allows the flavors of the caramelized onions, mushrooms, and kale to meld beautifully, creating a comforting and rich base for your hearty soup.
Step 6: Finish with Coconut Milk
After simmering, stir in 1 cup of coconut milk or cream, ensuring it blends well with the soup. Heat through for an additional 5 minutes, adjusting the seasoning if necessary. The addition of coconut milk will give your Wild Mushroom, Caramelized Onion, and Kale Soup a creamy texture and a touch of richness, perfect for those chilly evenings.

Make Ahead Options
Preparing Wild Mushroom, Caramelized Onion, and Kale Soup in advance is a game-changer for busy weeknights! You can sauté the onions and mushrooms up to 24 hours before serving and store them in the fridge, allowing the flavors to develop beautifully. Additionally, chop the kale and keep it refrigerated for up to 3 days; this ensures it stays fresh and vibrant. When you’re ready to enjoy your soup, simply combine the prepped ingredients with the broth and coconut milk, and simmer until heated through. This method not only saves time but also guarantees your soup will be just as delicious and nourishing as if freshly made!

Expert Tips for Wild Mushroom, Caramelized Onion, and Kale Soup
-
Patience with Onions: Allow your sweet onions to caramelize slowly over medium heat. Rushing this step can lead to bitterness instead of the lovely sweetness that enhances the soup’s flavor.

Right Time for Kale: To keep the kale’s vibrant color and texture, add it in the last 5 minutes of cooking. Overcooking it can turn it mushy and unappetizing.
-
Avoid Steaming Mushrooms: Sauté mushrooms in batches if your pot is crowded. A hot pan is crucial for achieving a deep golden color and rich umami flavor in your Wild Mushroom, Caramelized Onion, and Kale Soup.
-
Flavor Intensification: For an extra flavor boost, let the soup rest in the fridge overnight. The flavors deepen and become even more satisfying after a day!
-

-
Experiment with Broth: Homemade broth makes a notable difference in flavor. If using store-bought, opt for low-sodium varieties to better control seasoning.
