Step-by-Step Preparation of Wild Mushroom Caramelized Onion and Kale Soup
Are you ready to immerse yourself in a warm bowl of wild mushroom, caramelized onion and kale soup? This comforting dish is packed with flavor and nutrients, making it perfect for any day of the week. Follow these simple steps to create a soup that is both delicious and nourishing.
Caramelize the Sweet Onion
Start by heating 2 tablespoons of extra-virgin olive oil in a large pot over medium heat. Once the oil shimmers, add your sliced sweet onions in an even layer. Patience is key here—slowly caramelizing the onions over 10 to 15 minutes allows their natural sugars to develop, giving your soup a rich flavor.

Sauté Garlic and Season
Once your onions are golden-brown and fragrant, add in 4 finely chopped garlic cloves. Sprinkle 1 teaspoon of sea salt and ½ teaspoon of freshly cracked black pepper into the mix. Stir it all together and let the garlic sauté for about 1–2 minutes, just until it becomes aromatic. Be careful not to overdo it; burnt garlic can leave a bitter taste.
Add the Wild Mushrooms
Now, let’s introduce our star ingredient: the mushrooms. Toss in 2 cups of whole shiitake mushrooms along with 2 cups of sliced baby bella or cremini mushrooms. Give them a good stir so they get coated in that onion-garlic goodness.
Cook the mushrooms for 5–7 minutes. They’ll release some moisture, and as they start to brown, you’ll witness how much depth they add to the soup. If you're interested in exploring different mushroom varieties, see this guide on Creamy Mushroom Soup for fascinating substitutions.
Incorporate the Broth and Kale
Next, it’s time to pour in 4 cups of organic chicken or vegetable broth. Stir everything to combine, ensuring to scrape up those brown bits on the pot’s bottom, as they hold intense flavor. Then, add in 2 cups of loosely chopped kale. If you're not a kale fan, feel free to swap it with spinach or swiss chard, which can also work beautifully in this wild mushroom soup.
Cover the pot and let it simmer on low for about 20 minutes. This step allows all the flavors to meld together.
Finish with Coconut Milk
Your soup will be smelling incredible by now! To add a velvety finish, stir in ½ cup of coconut milk or coconut cream. Warm it through for just a minute or two—this addition enriches the soup's texture and balances the earthy flavors beautifully. Don’t forget to taste before serving; you might want to adjust with a pinch more salt or cracked black pepper!
Enjoy this nutrient-rich wild mushroom soup hot and steamy, perfect for a cozy night in! Want to kick it up a notch? A sprinkle of red pepper flakes adds a nice little kick. What’s stopping you from crafting this delicious dish today?

Variations on Wild Mushroom Caramelized Onion and Kale Soup
Vegan Alternative with Different Greens
For those seeking a vegan twist, simply swap the chicken broth with vegetable broth and replace the coconut milk with a nut-based cream or blend of silken tofu for a creamy texture. Instead of kale, try using collard greens or Swiss chard for a different flavor profile. Collards stand up beautifully to simmering, while Swiss chard adds a subtle sweetness to this earthy wild mushroom soup.
Adding Legumes for Protein
If you're looking to boost the protein content of your soup, consider adding canned beans or lentils. Chickpeas or white beans blend seamlessly with the robust flavors of mushrooms and caramelized onions. Just toss them into the pot during the last 10 minutes of cooking, allowing them to heat through. This small addition not only enhances nutrition but provides a hearty, satisfying meal perfect for busy weeknights. Don't forget to check out our guide on plant-based protein sources for more ideas!
