How to Make Simple Wild Mushroom, Caramelized Onion And Kale Soup

1. Heat 2 tablespoons of olive oil in a large pot over medium heat. Add the sliced onions and cook slowly, stirring occasionally, for about 20 minutes until deeply golden and caramelized.
2. Add the garlic and thyme to the caramelized onions and cook for 1 minute until fragrant.
3. In a separate pan, heat the remaining 1 tablespoon of olive oil and sauté the wild mushrooms over medium-high heat for 5-7 minutes until browned and tender. Add these mushrooms to the pot with the onions.
4. Sprinkle the flour over the mushroom and onion mixture and stir well to coat; cook for 1-2 minutes to remove the raw flour taste, stirring constantly. (Skip this step if you prefer a thinner broth.)
5. Pour in the broth, bring the soup to a simmer, then add the chopped kale. Cook for another 10 minutes until the kale is tender but still bright green.
6. Stir in the butter (if using), salt, and pepper. Taste and adjust seasonings as needed.
7. Ladle the soup into bowls and garnish with extra thyme or a drizzle of olive oil if desired. Serve warm with crusty bread.

Tips for the Best Results

• Use a mix of wild mushrooms for a deeper, more complex flavor.
• Caramelize onions slowly over medium-low heat to develop natural sweetness.
• Remove kale stems before chopping to avoid bitterness and tough texture.
• Adjust seasoning at the end since broth and mushrooms can vary in saltiness.
• If you want a creamier texture, blend half the soup and then mix it back in.

Storage and Reheating

Store leftover soup in an airtight container in the refrigerator for up to 4 days. When ready to eat, gently reheat on the stovetop over low heat, stirring occasionally until warmed through.

This soup also freezes well. Portion it into freezer-safe containers or bags and freeze for up to 3 months. Thaw overnight in the fridge before reheating on the stove.

Frequently Asked Questions

Can I use other greens instead of kale?

Yes, you can substitute spinach, Swiss chard, or collard greens if you prefer. Just add them toward the end of cooking as they tend to cook faster than kale.

Is it necessary to caramelize the onions?

Caramelizing the onions adds a rich sweetness that balances the earthiness of the mushrooms and bitterness of the kale. However, if you’re short on time, you can soften them quickly but the flavor won’t be as deep.

Can I make this soup vegan?

Absolutely! Use vegetable broth and omit the butter or replace it with a vegan alternative to keep the soup fully plant-based.

How do I store leftover soup to keep it fresh?

Cool the soup completely before refrigerating. Store it in airtight containers and consume within 4 days. For longer storage, freeze in portions and thaw before reheating.
