Method
- In a large pot, melt the butter and olive oil over medium-low heat. Add the shallots and cook, stirring occasionally, until they soften, about 4 minutes. Stir in the garlic and cook for an additional minute. Sprinkle the flour over the mixture and cook for 1 minute, stirring and scraping the bottom of the pot.
- Add the mushrooms and beef Better Than Bouillon; cook for 3 minutes or so, stirring occasionally until mushrooms begin to release their liquid. Pour in the cognac and deglaze the pot, using a wooden spoon to scrape up any bits while letting the alcohol cook off, about 1-2 minute(s).
- Add Dijon mustard, Parmesan rind, chicken broth, salt, and pepper; bring to a boil, then lower the heat and simmer, uncovered, for 20 minutes, until the mushrooms are tender.
- Add sour cream to a medium-sized bowl. Slowly whisk in 1 cup of broth until incorporated into the sour cream. Don't worry if there are mushrooms in the broth.
- Remove from heat. Stir in the half and half, Parmigiano Reggiano, thyme, sage, and dill. Add tempered sour cream and whisk until incorporated. Bring to a low-simmer and cook for a few more minutes. Taste; adjust seasoning, if necessary.
- OPTIONAL: Using an immersion blender, purée the soup until you reach your desired consistency. Sometimes I do this and other times, I leave the soup as is. It depends on what mushrooms I'm using and how small I've cut the pieces.
- Ladle into bowls and top with fresh herbs (optional). This soup will keep in the fridge for up to 3 days.
