Step 1

Rinse the mushrooms under cold water and immediately pat them dry with a paper towel. Pull out the stems and then slice the mushrooms.

Step 2

Heat the olive oil in a large skillet over medium-high heat. Once the pan is hot, add the mushrooms and cook for 3-5 minutes, stirring often, until they start to soften and brown. Don't stir them too often, as you want them to get a nice golden sear on the sides for maximum flavor.

Step 3

Add the chopped shallot and cook, stirring often, for 1 minute.

Step 4

Add the garlic and balsamic vinegar and cook, stirring often, for 1 minute. Season with salt and pepper, to taste. Serve, garnished with chopped fresh parsley or thyme, if desired.
