Ingredients

Scale

For the Caramelized Onions:

  • 2 tablespoons olive oil
  • 2 large yellow onions, thinly sliced
  • 1 teaspoon sugar (optional, for faster caramelization)
  • Pinch of salt

For the Soup:

  • 2 tablespoons butter (or olive oil for vegan)
  • 3 garlic cloves, minced
  • 8 ounces wild mushrooms (shiitake, cremini, or oyster), sliced
  • 1 teaspoon thyme (fresh or dried)
  • 1/2 teaspoon smoked paprika (optional, for depth)
  • 1/4 cup dry white wine (optional)
  • 6 cups vegetable or chicken broth
  • 2 cups kale, stems removed and leaves chopped
  • 1/2 cup heavy cream or coconut milk (optional, for creaminess)
  • Salt and pepper, to taste

Optional Garnishes:

  • Crusty bread or croutons
  • Grated Parmesan or nutritional yeast
  • Chopped fresh parsley

Instructions

  1. Caramelize the Onions:
    • Heat olive oil in a large skillet over medium-low heat.
    • Add the sliced onions, pinch of salt, and sugar (if using).
    • Cook, stirring occasionally, for 20-25 minutes, or until the onions are golden brown and caramelized.
    • Remove from heat and set aside.
  2. Sauté the Mushrooms:
    • In a large pot, melt butter (or heat olive oil) over medium heat.
    • Add the garlic and sauté for 1 minute, until fragrant.
    • Add the mushrooms, thyme, and smoked paprika (if using).
    • Cook for 5-7 minutes, stirring occasionally, until the mushrooms are browned and tender.
    • Deglaze the pot with white wine (if using), scraping up any browned bits. Allow the wine to simmer for 2 minutes.
  3. Build the Soup:
    • Add the caramelized onions and broth to the pot with the mushrooms.
    • Bring to a simmer and cook for 10 minutes to allow the flavors to meld.
    • Stir in the kale and cook for another 5 minutes, until the kale is tender.
  4. Add Creaminess (Optional):
    • If using heavy cream or coconut milk, stir it in during the last 2 minutes of cooking.
    • Season with salt and pepper to taste.
  5. Serve:
    • Ladle the soup into bowls and garnish with crusty bread, grated Parmesan, or fresh parsley.
    • Serve warm and enjoy!
