Step‑by‑Step Instructions for Wild Mushroom, Caramelized Onion and Kale Soup
Step 1: Sauté Onions
In a large pot, heat 2 tablespoons of extra-virgin olive oil over medium heat. Add 1 sliced sweet onion and sauté, stirring occasionally, until the onions turn golden brown and fragrant, about 10 to 15 minutes. The goal is to achieve that perfect caramelization—watch for a rich, warm hue and a sweet aroma wafting through your kitchen.
Step 2: Add Garlic
Next, stir in 4 cloves of finely chopped garlic, along with 1 teaspoon of sea salt and freshly cracked black pepper to taste. Cook this mixture for an additional 1 to 2 minutes until the garlic is fragrant and starts to soften. You want to evoke the warm, savory scents that blend beautifully with the caramelized onions.
Step 3: Cook Mushrooms
Now, add 1 cup each of shiitake and baby bella mushrooms to the pot. Increase the heat slightly and cook for about 5 to 7 minutes, stirring occasionally, until the mushrooms have softened and begun to brown. This step enhances the umami flavor of your Wild Mushroom, Caramelized Onion and Kale Soup, creating a rich, savory base.
Step 4: Combine Ingredients
Pour in 4 cups of organic chicken or vegetable broth and bring the mixture to a gentle boil. Once boiling, add 4 cups of chopped kale leaves. Reduce the heat, cover the pot, and let the soup simmer for 20 minutes. This allows the flavors to meld together, and the kale will wilt beautifully, adding color and nutrients to your bowl.
Step 5: Finish Soup
After simmering, stir in 1 cup of coconut milk or cream, blending until the soup is uniformly creamy and warmed through, about 2 to 3 minutes. Taste your Wild Mushroom, Caramelized Onion and Kale Soup and adjust the seasoning if needed. The result should be a comforting, rich blend, perfect for cozy evenings.

Wild Mushroom, Caramelized Onion, and Kale Soup Recipe FAQs
How do I select the best mushrooms for this soup?
Absolutely! When choosing your mushrooms, look for firm, plump ones with smooth, unblemished caps. Shiitake mushrooms should be free from dark spots, while baby bellas should have a rich brown color. If the mushrooms have started to dry out or show signs of slime, it’s best to seek fresher options.
What’s the best way to store leftover soup?
Very! For best results, transfer your Wild Mushroom, Caramelized Onion, and Kale Soup into an airtight container and refrigerate it for up to 5 days. If you want to make it ahead for meal prep, freezing is a great choice as well.
Can I freeze this soup for later?
Absolutely, you can! To freeze your soup, let it cool completely, then ladle it into freezer-safe, airtight containers. Leave about an inch of space at the top for expansion, and label them with the date. Your soup will stay fresh for up to 3 months. To reheat, simply thaw in the fridge overnight, and then warm gently on the stove, adding a splash of broth if necessary.
What should I do if the soup is too salty?
No worries, this happens to the best of us! If your soup turns out too salty, try adding a peeled, quartered potato to the pot and simmering for about 20 minutes. The potato absorbs some of the saltiness, and you can remove it before serving. Alternatively, adding a splash of coconut milk can help balance the flavors.
Is this soup safe for gluten-intolerant individuals?
Absolutely! Just be sure to use gluten-free broth as your base. Many store-bought broths contain gluten, so double-check the labels to ensure they meet your dietary needs. This way, everyone can enjoy your hearty Wild Mushroom, Caramelized Onion, and Kale Soup without worry!
What types of greens can I add besides kale?
Very! You can easily swap kale for other leafy greens like spinach or Swiss chard. Just remember to add them in the last few minutes of cooking to retain their vibrant color and nutritional benefits. This flexibility allows you to customize your soup according to what you have on hand!
