How do you make mushroom steak sauce?

This sauce starts with plenty of fresh sliced mushrooms, which are cooked in butter until golden brown. Garlic is added for flavor, and flour is used for the thickening agent. The next step is to add beef broth, Worcestershire sauce and pan drippings from your cooked steak. After the sauce has thickened, stir in a little more butter, then pour it over your steak and enjoy.

Tips for mushroom steak sauce

I cut my mushrooms into thick slices because I find them easier to eat that way, but you can cut your mushrooms in half if you prefer. Just be sure to adjust the cooking time accordingly.
The mushrooms will release a lot of liquid as they cook. If you wait patiently, that liquid will evaporate off and when that happens, the mushrooms will get that great caramelized and browned exterior.
I add the garlic towards the end of the cooking time so that it doesn’t burn.
I typically add a sprinkling of fresh parsley to garnish my mushroom sauce, but other great options are dill, chives or thyme leaves.
This recipe calls for button mushrooms, but you can substitute other types of mushrooms such as cremini, portobello, shiitake or oyster.

HOW DO YOU CLEAN MUSHROOMS?

The best way to clean mushrooms is to use a damp paper towel to gently rub the dirt off of each mushroom. You can also rinse your mushrooms in a colander, but be sure to rinse them briefly; do not soak them in water.
