Ingredients

Scale

Main Ingredients:

  • 3 cups sliced onions
  • 1 pound (454 grams) cremini mushrooms
  • 4 cups (946 milliliters) low sodium beef broth
  • 2 cups (473 milliliters) low sodium chicken broth

Protein and Fat Components:

  • 4 slices bacon or 1/4 pound (113 grams) pancetta
  • 2 tablespoons (30 milliliters) butter
  • 3/4 cup (177 milliliters) heavy whipping cream

Seasoning and Flavor Enhancers:

  • 2 cloves garlic, chopped
  • 1/4 cup (59 milliliters) white wine (chardonnay is great in soups)
  • 3 sprigs fresh thyme or 1/2 teaspoon dried thyme
  • Salt and pepper to taste

Instructions

  1. Gently melt butter in a spacious skillet, introducing sliced onions and reducing heat to transform them into a luxurious caramel-hued delicacy through patient, attentive stirring.
  2. Integrate sliced mushrooms with caramelized onions, allowing them to soften and release their rich, earthy essence.
  3. Introduce minced garlic, infusing the mixture with aromatic depth for approximately one minute.
  4. Elevate the flavor profile by deglazing the pan with white wine, letting the liquid reduce and concentrate its essence.
  5. Pour chicken and beef broths into the skillet, accompanied by fresh thyme sprigs, then cover and allow the mixture to gently simmer for ten minutes.
  6. Simultaneously crisp bacon or pancetta in a separate pan until achieving a perfect golden-brown texture.
  7. Carefully transfer the soup mixture to a blender, reserving a portion of chunky onions and mushrooms, and puree until achieving a velvety, smooth consistency.
  8. Return the pureed soup to the original pot, reuniting it with the reserved chunky components, and bring to a gentle simmer.
  9. Finish the soup by swirling in heavy cream, seasoning with salt and pepper, and crowning the dish with crispy crumbled bacon or pancetta before serving.

Notes

  • Caramelize onions slowly on low heat to develop deep, rich flavor without burning, stirring frequently to prevent sticking.
  • Slice mushrooms uniformly for even cooking and consistent texture throughout the soup.
  • Use a combination of chicken and beef broth to create a more complex, layered taste profile that enhances the overall depth of the dish.
  • For a vegetarian version, substitute vegetable broth and replace bacon with crispy roasted mushroom bits or toasted nuts as a crunchy topping.
