Tips & Tricks

Preparation tips

You can tweak this recipe depending on your personal preference. Some people like to use cremini mushrooms while others choose button mushrooms since they’re cheaper. If you have cheese at home, you may use it as a topping along with the sliced mushrooms. Using grass-fed butter instead of regular butter will make your soup taste better.
