Ingredients
  

  • 2 tablespoons butter
  • 3 cups onion sliced
  • 1 pound cremini mushrooms
  • 2 cloves garlic chopped
  • ¼ cup white wine chardonnay is great in soups
  • 4 cups low sodium beef broth
  • 2 cups low  sodium chicken broth
  • 3 sprigs fresh thyme or ½ teaspoon dried thyme
  • 4 slices bacon or ¼ pound pancetta
  • ¾ cup heavy whipping cream
  • salt and pepper to taste

Instructions
 

  • Melt butter in a large pot. Add onions, reduce heat, and cook slowly until they turn a deep caramel color, stirring frequently.
  • Add sliced mushrooms to the onions and sauté until softened.
  • Stir in garlic and cook for another minute.
  • Pour in the white wine and simmer until mostly evaporated.
  • Add chicken broth, beef broth, and thyme. Cover and let simmer for about 10 minutes.
  • Cook the bacon or pancetta until crispy, while the soup simmers.
  • Transfer the soup to a blender, reserving about 1 cup of the chunky onions and mushrooms. Blend until smooth.
  • Return the blended soup to the pot with the reserved chunks. Stir in the cream, season with salt and pepper, and garnish with crumbled bacon or pancetta.

Notes

Chef Jenn’s Tips

  • Caramelizing onions takes time, so you can do this step ahead and store them in the fridge.
  • They add more flavor than white mushrooms. If using portobellos, remove the gills to avoid discoloration.
  • Combining chicken and beef broth gives a balanced flavor.
  • When blending hot soup, remove the center lid plug and cover with a towel to avoid splatters.
